California Academy of Sciences
–
The California Academy of Sciences is a natural history museum in San Francisco, California, that is among the largest museums of natural history in the world, housing over 26 million specimens. Completely rebuilt in 2008, the building covers 400,000 square feet and is among the newest natural history museums in the United States, the primary building in Golden Gate Park reopened on September 27,2008. The Academy Fellows are, in turn, ominated by their colleagues, underlying these operations is a staff of hundreds of employees who operate the day-to-day functions without which the Academy could not offer its programs. The operations branch of the Academy is divided into three departments, Building Operations, Guest Operations, and IT Services, in fact, unbeknownst to most patrons, research and administrative facilities occupy nearly 50% of the Academys physical structure. Prior to being replaced, the old Academy building attracted approximately half a million each year. As has been the case from the start, the main thrust of the exhibits is natural history, Morrison Planetarium - features the worlds largest completely digital planetarium dome measuring in at 27. There also is an emphasis on environmental concerns, with all the various departments collaborating closely to focus on systematic biology. Academy researchers study life around the world, a 2011 expedition to the Philippines discovered an estimated 300 species new to science, the Academy publishes the peer-reviewed journal Proceedings of the California Academy of Sciences, as well as Occasional Papers, Memoirs, and Special Publications. The California Academy of Natural Sciences was founded in 1853, only three years after California joined the United States, becoming the first society of its kind in the Western US. Its stated aim was to undertake a systematic survey of every portion of the State. It was renamed as the more inclusive California Academy of Sciences in 1868, in 1892, Alice Eastwood, a botanist, was hired by the Academy and worked there until she retired in 1949. Fortunately, the 1905-1906 scientific collecting expedition to the Galápagos Islands already was underway, in 1916, the Academy moved to the North American Hall of Birds and Mammals in Golden Gate Park, the first building on the site that was to become its permanent home. In 1923, the Steinhart Aquarium was added, followed in 1934 by the Simson African Hall, the post-war years saw a flurry of new construction on the site, the Science Hall was added in 1951, followed by the Morrison Planetarium in 1952. The Morrison Planetarium was the seventh major planetarium to open in the United States and featured a one-of-a-kind star projector, the Academy Projector produced a remarkably natural-looking star field. It projected irregularly shaped stars, rather than the circular stars projected by many optical star projectors, the irregular shapes were created by placing variously sized grains of silicon carbide onto the glass star plates by hand, then aluminizing the plates, and brushing away the silicon carbide grains. In 1959, the Malliard Library, Eastwood Hall of Botany, in 1969, another new building, Cowell Hall, was added to the site. In 1976, several new galleries were opened, and the year, in 1977. Prior to the old building being torn down in 2005, there was a Life through Time gallery, housing a display on evolution

Los Angeles, officially the City of Los Angeles and often known by its initials L. A. is the cultural, financial, and commercial center of Southern California. With a census-estimated 2015 population of 3,971,883, it is the second-most populous city in the United States, Los Angeles is also the seat of Los Angeles County, the most populated county in the United States. The citys inhabitants are referred to as Angelenos, historically home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California. The city was founded on September 4,1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence, in 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, thereby becoming part of the United States. Los Angeles was incorporated as a municipality on April 4,1850, the discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California, nicknamed the City of Angels, Los Angeles is known for its Mediterranean climate, ethnic diversity, and sprawling metropolis. Los Angeles also has an economy in culture, media, fashion, science, sports, technology, education, medicine. A global city, it has been ranked 6th in the Global Cities Index, the city is home to renowned institutions covering a broad range of professional and cultural fields, and is one of the most substantial economic engines within the United States. The Los Angeles combined statistical area has a gross metropolitan product of $831 billion, making it the third-largest in the world, after the Greater Tokyo and New York metropolitan areas. The city has hosted the Summer Olympic Games in 1932 and 1984 and is bidding to host the 2024 Summer Olympics and thus become the second city after London to have hosted the Games three times. The Los Angeles area also hosted the 1994 FIFA mens World Cup final match as well as the 1999 FIFA womens World Cup final match, the mens event was watched on television by over 700 million people worldwide. The Los Angeles coastal area was first settled by the Tongva, a Gabrielino settlement in the area was called iyáangẚ, meaning poison oak place. Gaspar de Portolà and Franciscan missionary Juan Crespí, reached the present site of Los Angeles on August 2,1769, in 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. The Queen of the Angels is an honorific of the Virgin Mary, two-thirds of the settlers were mestizo or mulatto with a mixture of African, indigenous and European ancestry. The settlement remained a small town for decades, but by 1820. Today, the pueblo is commemorated in the district of Los Angeles Pueblo Plaza and Olvera Street. New Spain achieved its independence from the Spanish Empire in 1821, during Mexican rule, Governor Pío Pico made Los Angeles Alta Californias regional capital

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Science museum
–
A science museum is a museum devoted primarily to science. Older science museums tended to concentrate on static displays of objects related to history, paleontology, geology, industry and industrial machinery. Modern trends in museology have broadened the range of subject matter, many if not most modern science museums — which increasingly refer to themselves as science centers or discovery centers — also emphasize technology, and are therefore also technology museums. The mission statements of science centers and modern museums vary, but they are united in being places that make science accessible and they are an integral and dynamic part of the learning environment, promoting exploration from the first Eureka. As early as the Renaissance, many aristocrats collected curiosities for display to their family, universities and particularly medical schools also maintained study collections of specimens for their students. Scientists and collectors displayed their finds in private cabinets of curiosities, such collections were the predecessors of modern natural history museums. The first purpose-built museum covering natural philosophy and open to the public from 1683 was the original Ashmolean museum in Oxford, the first dedicated science museum was the Museo de Ciencias Naturales, in Madrid, Spain. Opened in 1752, it almost disappeared during the Franco regime, the Utrecht University Museum, among others, still displays an extensive collection of 18th-century animal and human rarities in its original setting. Another line in the genealogy of science museums came during the Industrial Revolution, for example, the Great Exhibition in The Crystal Palace eventually gave rise to Londons Science Museum. In America, various Natural History Societies established collections in the early 19th century, notable was the early New England Museum of Natural History, which opened in Boston in 1864. The Academy of Science of Saint Louis was founded in 1856 as the first scientific organization west of the Mississippi, the modern interactive science museum appears to have been pioneered by Munich’s Deutsches Museum in the early 20th century. This museum had moving exhibits where visitors were encouraged to push buttons, the concept was taken to the US by Julius Rosenwald, chairman of Sears, Roebuck and Company, who visited the Deutsches Museum with his young son in 1911. He was so-captivated by the experience that he decided to build a museum in his home town. Chicagos Museum of Science and Industry opened in phases between 1933 and 1940, in 1959 the Museum of Science and Natural History was formally created by the Academy of Science of Saint Louis, featuring many interactive science and history exhibits. In August 1969, Frank Oppenheimer dedicated his new Exploratorium in San Francisco almost completely to interactive science exhibits, the Exploratorium published the details of their own exhibits in Cookbooks that served as an inspiration to many other museums around the world. Opened in September 1969, the Ontario Science Centre continued the trend of featuring interactive exhibits rather than static displays, in 1973, the first Omnimax theater opened as the Reuben H. Fleet Space Theater and Science Center in San Diegos Balboa Park, the tilted-dome Space Theater doubled as a planetarium. The Science Center was an Exploratorium-style museum included as a part of the complex

Science centers connect people with science, give science a presence in the community and offer people of all ages and backgrounds the opportunity to ask questions, discuss, Science centers provide firsthand experience and an opportunity to develop intuitions about the natural world. Many schools rely on science centers for field trips and auditorium programs, hands-on curriculum, science kits. In the words of Frank Oppenheimer, founder of San Franciscos Exploratorium, “No one flunks a museum. ”For some, the interests awakened by science center experiences have turned into a passion for science, and the beginning of a lifetime devoted to teaching or research. ASTC’s goal is to support efforts of science centers and museums, in addition to their staff, visitors. Some ASTC member institutions also participate in ASTC’s Passport Program, more than 300 institutions in over a dozen countries are currently participating in the Passport Program. ASTC provides professional development opportunities for those who work in science centers, ASTC provides CoPs with resources and support for connecting with colleagues, convening meetings, and organizing workshops, among other activities. They work with partners to support sharing of knowledge and experience, and assist with planning, marketing, ASTC Connect is a learning and resource-sharing area for the informal science education community. Discussion forums, online workshops, and self-paced tutorials are hosted in collaboration with partners throughout the field. The YOUmedia Network is a group of libraries, museums and community-based organizations that invite people to create, learn. There are currently 24 Learning Lab sites operating across the country with programs that are driven by youth interests and connect learning directly back to school, careers, and other realms. This program was inspired by President Obama and other world leaders’ commitment to strengthening the science, technology, engineering, to date, more than 100 science centers have joined the challenge. ExhibitFiles is a community of exhibit practitioners building a shared collection of exhibition records. Its a place to connect with colleagues, find out about exhibits, exhibitFiles was developed to preserve and share experiences and materials that are often unrecorded, temporary, and hard to locate. Visitors to the site can search for, and post exhibitions rentals. ASTC and the National Writing Project received a grant from the National Science Foundation to design a program that will integrate science, through this program, ten partnerships will be created between NWP sites and ASTC-member science centers and museums to develop innovative programs for educators and youth

Expo Park/USC station
–
Expo Park/USC is an at-grade light rail station in the Los Angeles County Metro Rail system. It is located at Exposition Boulevard and Trousdale Parkway, directly between the USC campus and Exposition Park, in the University Park neighborhood of Los Angeles and it also serves the Los Angeles Memorial Coliseum and the under construction Banc of California Stadium. This station is served by the Expo Line, Expo Line service hours are approximately from 4 AM to 12,30 AM daily. Service resumed Saturday, April 28,2012, regular scheduled service resumed Monday, April 30,2012. Expo Park/USC Station is located in the median of Exposition Boulevard, on the east side of Trousdale/Exposition, the stations entrance is on the east side of Trousdale/Exposition. The stations platforms slope down slightly toward the east, in order to accommodate the lines descent into a tunnel passes under Figueroa Street. The stations art was created by artist Robbert Flick, the untitled installation includes sequences of photographs taken on the boulevards near the station, creating a document of the local people and places as they were when the station was built. The USC main campus occupies the area to the north of the station, to the south is Exposition Park, which includes several popular L. A. Many stakeholders cited the importance of the station, citing the convenient access it would provide the USC students/employees, the administration of USC opposed at-grade light-rail along Exposition Boulevard, claiming that light-rail would separate the campus from Exposition Park. USC President Steven Sample, in particular, was opposed to the project, dr. Sample said he feared the line would create physical and psychological barriers between USC, Exposition Park, and the local community, and would be dangerous for pedestrians. However, general sentiment of students and neighbors was in support of the line, the Coliseum Commission took a strong position in support of this station, and the USC Student Senate also passed a resolution. The report also recommended a tunnel segment under the impacted intersections of Exposition/Figueroa. Once the FEIR had been approved, Expo worked to secure the funds for this station, one other issue remaining to be resolved was USC’s request for special architecture for the three stations serving the campus. Ultimately, USC did not contribute toward the cost of the station, Expo also abandoned any considerations for special architecture requested by USC. On September 19,2007, the board of Metro approved funding for the cost of the station and this allowed the station to be built along with the rest of Phase 1. It was completely rebuilt for the opening of the Expo Line from little more than a stop marker. Regular scheduled service resumed Monday, April 30,2012 and it is the last former station stop of the Santa Monica Air Line to be re-opened. The Expo line travels north on a new right-of-way along Flower street from this stop, the original Air line right-of-way remains owned by Metro and continues east to the Blue line tracks, however no plans are in place for its use

California executive branch
–
The California executive branch consists of elected officers and other offices and officers. The elected executive officers are, Total number of employees is 227,536 excluding California State Universities, in 2004, there were 4,462 job classifications, many of which had no employees occupying the position, as a workaround for certain hiring practices. As part of a civil service reform initiative beginning in 2013,700 job titles were eliminated, two agencies, the California Department of Human Resources and the California State Personnel Board, oversee the states civil service system. The duties which apply to one agency versus the other is not always entirely clear, in the 1980s, a recommendations to decentralize hiring to departments was implemented. In 2012, the California Government Operations Agency was created under Governor Jerry Brown and its director, Marybel Batjer, launched an initiative of civil service reform intended to make state employment more attractive to talented employees relative to the private sector. In 2015, the first engagement survey of employees was conducted using a sample of 5,000. In 2016, the state rolled out a new hiring website, unusually, it was programmed by state employees rather than an external contractor. Agencies under the direction of a secretary that report directly to the Governor are cabinet-level agencies, some agencies such as the California State Controller, Attorney General of California, and California Insurance Commissioner and are headed by independent elected officials. The state auditor is the California Bureau of State Audits which is appointed by the governor with confirmation by the legislature, one relatively new top-level agency, California Government Operations Agency, was created in 2012 to help modernize the government. Exceptions include the head of the Department of the California Highway Patrol, notable exceptions include the California Public Utilities Commission and the California Department of Industrial Relations, which are both headquartered in San Francisco. Other defunct statewide elected offices that no longer exist include the Comptroller, the Surveyor General, in June 2012, Governor Jerry Brown obtained approval from the Legislature to proceed with a reorganization plan.

Space Shuttle Endeavour
–
Space Shuttle Endeavour is a retired orbiter from NASAs Space Shuttle program and the fifth and final operational shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135, Atlantis became the last shuttle to fly. The United States Congress authorized the construction of Endeavour in 1987 to replace Challenger, structural spares built during the construction of Discovery and Atlantis were used in its assembly. NASA chose, on cost grounds, to build Endeavour from spares rather than refitting Enterprise or accepting a Rockwell International proposal to build two shuttles for the price of one. The orbiter is named after the British HMS Endeavour, the ship which took Captain James Cook on his first voyage of discovery and this is why the name is spelled in the British English manner, rather than the American English. This has caused confusion, including when NASA itself misspelled a sign on the pad in 2007. The Space Shuttle carried a piece of the wood from Cook’s ship inside the cockpit. The name also honored Endeavour, the Command Module of Apollo 15, Endeavour was named through a national competition involving students in elementary and secondary schools. Entries included an essay about the name, the story behind it and why it was appropriate for a NASA shuttle, Endeavour was the most popular entry, accounting for almost one-third of the state-level winners. The national winners were Senatobia Middle School in Senatobia, Mississippi, in the division and Tallulah Falls School in Tallulah Falls, Georgia. They were honored at ceremonies in Washington, D. C. including a White House ceremony where then-President George H. W. Bush presented awards to each school. Endeavour was delivered by Rockwell International Space Transportation Systems Division in May 1991 and first launched a year later, in May 1992, Rockwell International claimed that it had made no profit on Space Shuttle Endeavour, despite construction costing US$2.2 billion. On its first mission, it captured and redeployed the stranded INTELSAT VI communications satellite, the first African-American woman astronaut, Mae Jemison, was brought into space on the mission STS-47 on September 12,1992. Endeavour flew the first servicing mission STS-61 for the Hubble Space Telescope in 1993, in 1997 it was withdrawn from service for eight months for a retrofit, including installation of a new airlock. In December 1998, it delivered the Unity Module to the International Space Station, Endeavours last Orbiter Major Modification period began in December 2003 and ended on October 6,2005. Morgan was the backup for Christa McAuliffe who was on the ill-fated mission STS-51-L in 1986, as it was constructed later, Endeavour was built with new hardware designed to improve and expand orbiter capabilities. Most of this equipment was incorporated into the other three orbiters during out-of-service major inspection and modification programs. Endeavour’s upgrades include, A 40-foot diameter drag chute that reduced the orbiters rollout distance by 1,000 to 2,000 feet, the plumbing and electrical connections needed for Extended Duration Orbiter modifications to allow up to a 28-day mission

IMAX
–
IMAX is a motion picture film format and a set of cinema projection standards developed in Canada by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. IMAX has the capacity to record and display images of far greater size, since 2002, some feature films have been converted into IMAX format for displaying in IMAX theatres and some have also been partially shot in IMAX. IMAX is the most widely used system for special-venue film presentations, as of June 2016, there were 1,102 IMAX theatres in 69 countries. The desire to increase the impact of film has a long history. In 1929, Fox introduced Fox Grandeur, the first 70 mm film format, in the 1950s, the potential of 35 mm film to provide wider projected images was explored in the processes of CinemaScope and VistaVision, following multi-projector systems such as Cinerama. While impressive, Cinerama was difficult to install, during Expo 67 in Montreal, the National Film Board of Canadas In the Labyrinth and Fergusons Man and the Polar Regions both used multi-projector, multi-screen systems. Each encountered technical difficulties led them to found a company called Multiscreen. As it became clear that a single, large-screen image had more impact than multiple smaller ones and was a viable product direction. An IMAX 3D theatre also is in operation near the former Expo 67 site at the Montreal Science Centre in the Port of Old Montreal, tiger Child, the first IMAX film, was demonstrated at Expo 70 in Osaka, Japan. The first permanent IMAX installation was built at the Cinesphere theatre at Ontario Place in Toronto and it debuted in May 1971, showing the film North of Superior. The installation is still in place, however, Ontario Place is on hiatus for redevelopment, during Expo 74 in Spokane, Washington, an IMAX screen that measured 27 m ×20 m was featured in the US Pavilion. It became the first IMAX Theatre to not be partnered with any brand of movie theaters. About five million visitors viewed the screen, which covered the total visual field when looking directly forward. This created a sensation of motion in most viewers, and motion sickness in some, much to the dismay of the majority of Spokane and the disapproval of the IMAX Corporation itself, it will be demolished to make way for a parking lot. Another IMAX 3D theater was built in Spokane, not too far from where the original was. However, its screen-size is less than half that of the original, due to protests, the IMAX Corporation has been able to remodel the area with the city, and turn the U. S. Pavilion itself into the first permanent outdoor IMAX screen, the first permanent IMAX Dome installation, the Eugene Heikoff and Marilyn Jacobs Heikoff Dome Theatre at the Reuben H. Fleet Science Center, opened in San Diegos Balboa Park in 1973, the first permanent IMAX 3D theatre was built in Vancouver, British Columbia for Transitions at Expo 86, and was in use until September 30,2009

Climbing wall
–
A climbing wall is an artificially constructed wall with grips for hands and feet, usually used for indoor climbing, but sometimes located outdoors. Some are brick or wooden constructions, but on most modern walls, recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to lead climbing or bouldering. Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed onto the wall, with manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete, in addition to the textured surface and hand holds, the wall may contain surface structures such as indentions and protrusions, or take the form of an overhang, underhang or crack. Some grips are formed to mimic the conditions of outdoor rock, including some that are oversized, the earliest artificial climbing walls were typically small concrete faces with protrusions made of medium-sized rocks for hand holds. Schurman Rock in Seattle, WA is believed to be the first artificial climbing structure in the United States, the modern artificial climbing wall began in the UK. The first wall was created in 1964 by Don Robinson, a lecturer in Physical Education by inserting pieces of rock into a corridor wall, the first commercial wall was built in Sheffield, traditionally Englands centre for climbing due to its proximity to the Peak District. The first indoor climbing gym in the U. S. was established by Vertical World in Seattle, the simplest type of wall is of plywood construction, known colloquially in the climbing community as a woody, with a combination of either bolt-on holds or screw on holds. Bolt-on holds are fixed to a wall with iron bolts which are inserted through the hold, which will have specific bolt points, screw-on holds are, by contrast, usually much smaller, owing to the nature of their fixing. These holds are connected to the wall by screws which may be fastened anywhere on the walls surface, holds come in different colours, those of the same colour often being used to denote a route, allowing routes of different difficulty levels to be overlaid on one another. Coloured tape placed under climbing holds is another way that is used to mark different climbing routes. The grade of the route is usually a decision between the setter of the route and the first few people who climb the route. Many indoor climbing walls have people who are assigned to set these different climbing routes and these people are called route setters or course setters. As indoor climbing walls are used to check the development of climbers ability.

Motion simulator
–
A motion simulator or motion platform is a mechanism that encapsulates occupants and creates the effect/feelings of being in a moving vehicle. A motion simulator can also be called a base, motion chassis or a motion seat. The movement is synchronous with visual display and is designed to add an element to video gaming, simulation. When motion is applied and synchronized to audio and video signals, the result is a combination of sight, sound, all full motion simulators move the entire occupant compartment and can convey changes in orientation and the effect of false gravitational forces. These motion cues trick the mind into thinking it is immersed in the environment and experiencing kinematic changes in position, velocity. The minds failure to accept the experience can result in motion sickness, Motion platforms can provide movement on up to six degrees of freedom, three rotational degrees of freedom and three translational or linear degrees of freedom. Motion simulators can be classified according to whether the occupant is controlling the vehicle, or whether the occupant is a passive rider, common examples of occupant-controlled motion simulators are flight simulators, driving simulators, and auto racing games. Other occupant-controlled vehicle simulation games simulate the control of boats, motorcycles, rollercoasters, military vehicles, ATVs, or spacecraft, among other craft types. Examples of passive ride simulators are theme park rides where an entire theater system, an enhanced motion vehicle moves the motion base along a track in a show building. See Simulator ride and the Ride simulator section of article for more details on passive motion simulators. Historically, motion platforms have varied widely in scale and cost, modern motion platforms have become complicated machines, but they have simpler roots. Many of the early motion platforms were flight simulators used to train pilots, one of the first motion platforms, the Sanders Teacher, was created in 1910. The Sanders Teacher was an aircraft control surfaces fitted to the ground by a simple universal joint. When wind was present, the pilot in training was able to use the surfaces to move the simulator in the three rotational degrees of freedom. Around 1930, an advance in motion platform technology was made with the creation of the Link Trainer. The Link Trainer used the stick and external motors to control organ bellows located under the simulator. The bellows could inflate or deflate, causing the simulator to rotate with three degrees of freedom, in 1958 the Comet IV was designed using a three-degrees-of-freedom hydraulic system. After the Comet IV both the range of motion and the degrees of freedom exhibited by motion platforms was increased, the most expensive motion platforms utilize high-fidelity six-degrees-of-freedom motion, often coupled with advanced audio and visual systems

Smithsonian Affiliations
–
Any 5013 nonprofit or publicly operated educational entity can apply to become a Smithsonian Affiliate. The Smithsonian Affiliations program was established in 1996 by Smithsonian Secretary I. C, in 1993, the “Commission on the Future of the Smithsonian Institution” introduced the first proposal for initiatives promoting strategic, collections-based partnerships at the Institution. To Educate More of the Nation’s People, “Build collaborative partnerships with other museums, research centers, significant emphasis was placed on the benefits that partnerships with outside museums would create for the Institution. In 1996, during his year as Secretary, Heyman observed several challenges facing the Institution. In addition, the Institution began to see increased interest from outside museums for partnerships, Heyman responded to these challenges by creating the Smithsonian Affiliations program to oversee and manage collections-based partnerships with other museums. As stated by the minutes from the Smithsonian Board of Regents meeting housed in the Smithsonian Institution Archives, there is no value in being just the largest if we do not share the Smithsonian with as many people as possible. It means making sure those who travel to Washington can somehow experience and enjoy the Smithsonian. ”Michael Heyman “ challenge is extending the reach of our collections to communities, museums. The Board of Regents in September strengthened the policy to share our collections with others. ”Michael Heyman The program was received by museums across the country. The end of the fiscal year 1997 recognized 21 organizations as Affiliates, as of 2014 there are nearly 200 Affiliates. On October,21,2016, The National Civil Rights Museum in Memphis, Smithsonian Affiliations considers membership proposals from organizations that will advance the Smithsonian Institutions mission and strategic plan. Successful applicants are non-profit or publicly operated organizations whose missions are directed toward advancing research, knowledge, and education in science, history, and the arts. To qualify as an Affiliate, an organization must prove that it is able to care for, protect. Strong applicants are organizations that are fiscally sound and capable of developing, installing, Affiliates are also responsible for maintaining an annual membership fee. To become an Affiliate, organizations must submit an application package to Smithsonian Affiliations, applicants are required to provide documentation that confirms IRS status as a 5013 entity and a narrative detailing how the agreement will be mutually beneficial. Applications must also include a copy of the mission statement, an organizational chart, an annual report. Once approved, Affiliates are required to sign a Smithsonian Affiliations Agreement form and are assigned a National Outreach Manager to oversee loans, all loan agreements are set for defined period of time. Affiliate organizations participate in a number of training, outreach. Smithsonian Affiliations Visiting Professional Program, Professionals of Affiliate organizations receive training from Smithsonian officials while visiting and working in Washington, the Smithsonian Affiliations program supports, develops, and organizes a number of collaborative programs to promote education in science, art, history, and culture

Aquarium
–
An aquarium is a vivarium of any size having at least one transparent side in which water-dwelling plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles such as turtles, the term, coined by English naturalist Philip Henry Gosse, combines the Latin root aqua, meaning water, with the suffix -arium, meaning a place for relating to. An aquarist owns fish or maintains an aquarium, typically constructed of glass or high-strength acrylic, cuboid aquaria are also known as fish tanks or simply tanks, while bowl-shaped aquaria are also known as fish bowls. Size can range from a glass bowl to immense public aquaria. Specialized equipment maintains appropriate water quality and other characteristics suitable for the aquariums residents, in the Roman Empire, the first fish to be brought indoors was the sea barbel, which was kept under guest beds in small tanks made of marble. Introduction of glass panes around the year 50 AD allowed Romans to replace one wall of marble tanks, leonhard Baldner, who wrote Vogel-, Fisch- und Tierbuch in 1666, maintained weather loaches and newts. In 1832, Jeanne Villepreux-Power, a pioneering French marine biologist, in 1836, soon after his invention of the Wardian case, Dr. Nathaniel Bagshaw Ward proposed to use his tanks for tropical animals. In 1841 he did so, though only with aquatic plants, however, he soon housed real animals. In 1838, Félix Dujardin noted owning a saltwater aquarium, though he did not use the term, in 1846, Anne Thynne maintained stony corals and seaweed for almost three years, and was credited as the creator of the first balanced marine aquarium in London. English chemist Robert Warington experimented with a 13-gallon container, which contained goldfish, eelgrass and he published his findings in 1850 in the Chemical Societys journal. The keeping of fish in an aquarium became a popular hobby, in the United Kingdom, it became popular after ornate aquaria in cast-iron frames were featured at the Great Exhibition of 1851. In 1853, the craze was launched in England by Philip Henry Gosse who created and stocked the first public aquarium in the London Zoo which came to be known as the Fish House. Gosse coined the word aquarium, opting for this term in 1854 in his book The Aquarium, in this book, Gosse primarily discussed saltwater aquaria. In the 1850s, the became a fad in the United Kingdom. Tank designs and techniques for maintaining water quality were developed by Warington, edward Edwards developed these glass-fronted aquaria in his 1858 patent for a dark-water-chamber slope-back tank, with water slowly circulating to a reservoir beneath. Germans soon rivaled the British in their interest, in 1854, an anonymous author had two articles published about the saltwater aquaria of the United Kingdom, Die Gartenlaube entitled Der Ocean auf dem Tische. However, in 1856, Der See im Glase was published, discussing freshwater aquaria, during the 1870s, some of the first aquarist societies were appearing in Germany. Published in 1858, Henry D. Butlers The Family Aquarium was one of the first books written in the United States solely about the aquarium

Ecosystem
–
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles, as ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces. Energy, water, nitrogen and soil minerals are other essential components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun and it generally enters the system through photosynthesis, a process that also captures carbon from the atmosphere. By feeding on plants and on one another, animals play an important role in the movement of matter and they also influence the quantity of plant and microbial biomass present. Ecosystems are controlled both by external and internal factors, other external factors include time and potential biota. Ecosystems are dynamic entities—invariably, they are subject to disturbances and are in the process of recovering from some past disturbance. Ecosystems in similar environments that are located in different parts of the world can have different characteristics simply because they contain different species. The introduction of species can cause substantial shifts in ecosystem function. Internal factors not only control ecosystem processes but are controlled by them and are often subject to feedback loops. Other internal factors include disturbance, succession and the types of species present, although humans exist and operate within ecosystems, their cumulative effects are large enough to influence external factors like climate. Biodiversity affects ecosystem function, as do the processes of disturbance, classifying ecosystems into ecologically homogeneous units is an important step towards effective ecosystem management, but there is no single, agreed-upon way to do this. The term ecosystem was first used in 1935 in a publication by British ecologist Arthur Tansley, Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment. He later refined the term, describing it as The whole system, including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment. Tansley regarded ecosystems not simply as natural units, but as mental isolates, Tansley later defined the spatial extent of ecosystems using the term ecotope. G. Raymond Lindeman took these ideas one step further to suggest that the flow of energy through a lake was the driver of the ecosystem. Most mineral nutrients, on the hand, are recycled within ecosystems. Ecosystems are controlled both by external and internal factors, external factors, also called state factors, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem

Polar regions of Earth
–
The polar regions of Earth, also known as Earths frigid zones, are the regions of Earth surrounding its geographical poles. These regions are dominated by Earths polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica. The Arctic has various definitions, including the north of the Arctic Circle, or the region north of 60° north latitude. The Antarctic is usually defined as south of 60° south latitude, the 1959 Antarctic Treaty uses the former definition. The axial tilt of the Earth has an effect on climate of the polar regions. Since the polar regions are the farthest from the equator, they receive the least amount of sunlight and are therefore frigid, the large amount of ice and snow also reflects a large part of what little sunlight the Polar regions receive, contributing to the cold. There are many settlements in Earths north polar region, countries with claims to Arctic regions are, the United States, Canada, Denmark, Norway, Finland, Sweden, Iceland, and Russia. Arctic circumpolar populations often share more in common with other than with other populations within their national boundaries. As such, the polar region is diverse in human settlements. The southern polar region has no permanent human habitation, mcMurdo Station is the largest research station in Antarctica, run by the United States. Other notable stations include Palmer Station and Amundsen–Scott South Pole Station, Esperanza Base and Marambio Base, Scott Base, while there are no indigenous human cultures, there is a complex ecosystem, especially along Antarcticas coastal zones. Coastal upwelling provides abundant nutrients which feeds krill, a type of marine crustacea, other planets and natural satellites in the solar system have interesting quirks about their polar regions. Earths Moon is thought to contain deposits of ice in deep craters in its polar regions. Mars, like Earth, has ice caps. Meanwhile, on Uranus, the tilt of the planets axis leads to the poles alternately pointing almost directly at the Sun.

Space Shuttle external tank
–
A Space Shuttle External Tank was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three Space Shuttle Main Engines in the orbiter, the ET was jettisoned just over 10 seconds after MECO, where the SSMEs were shut down, and re-entered the Earths atmosphere. Unlike the Solid Rocket Boosters, external tanks were not re-used and they broke up before impact in the Indian Ocean, away from shipping lanes and were not recovered. The ET was the largest element of the shuttle. The ET was the backbone of the shuttle during launch, providing support for attachment with the Space Shuttle Solid Rocket Boosters. The tank was connected to each SRB at one forward attachment point and one aft bracket, in the aft attachment area, there were also umbilicals that carried fluids, gases, electrical signals and electrical power between the tank and the orbiter. Electrical signals and controls between the orbiter and the two rocket boosters were also routed through those umbilicals. Although the external tanks were discarded, it could have been possible to re-use them in orbit. Plans for re-use ranged from incorporation into a station as extra living or research space, as rocket fuel tanks for interplanetary missions. Another concept was to use the ET as a carrier for bulky payloads. One proposal was for the mirror of a 7-meter aperture telescope to be carried with the tank. Another concept was the Aft Cargo Carrier, over the years, NASA worked to reduce the weight of the ET to increase overall efficiency. For each pound of weight reduction, the capability of the shuttle spacecraft was increased almost one pound. The original ET is informally known as the Standard Weight Tank and was fabricated from 2219, a high-strength aluminum–copper alloy used for many aerospace applications. The first two, used for STS-1 and STS-2, were painted white to protect the tanks from ultraviolet light during the time that the shuttle spends on the launch pad prior to launch. After STS-4, several hundred pounds were eliminated by deleting the anti-geyser line and this line paralleled the oxygen feed line, providing a circulation path for liquid oxygen. This reduces accumulation of oxygen in the feed line during prelaunch tanking. After propellant loading data from tests and the first few space shuttle missions were assessed

Solar System
–
The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets, of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury. The Solar System formed 4.6 billion years ago from the collapse of a giant interstellar molecular cloud. The vast majority of the mass is in the Sun. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being composed of rock. The four outer planets are giant planets, being more massive than the terrestrials. All planets have almost circular orbits that lie within a flat disc called the ecliptic. The Solar System also contains smaller objects, the asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptunes orbit lie the Kuiper belt and scattered disc, which are populations of trans-Neptunian objects composed mostly of ices, within these populations are several dozen to possibly tens of thousands of objects large enough that they have been rounded by their own gravity. Such objects are categorized as dwarf planets, identified dwarf planets include the asteroid Ceres and the trans-Neptunian objects Pluto and Eris. In addition to two regions, various other small-body populations, including comets, centaurs and interplanetary dust clouds. Six of the planets, at least four of the dwarf planets, each of the outer planets is encircled by planetary rings of dust and other small objects. The solar wind, a stream of charged particles flowing outwards from the Sun, the heliopause is the point at which pressure from the solar wind is equal to the opposing pressure of the interstellar medium, it extends out to the edge of the scattered disc. The Oort cloud, which is thought to be the source for long-period comets, the Solar System is located in the Orion Arm,26,000 light-years from the center of the Milky Way. For most of history, humanity did not recognize or understand the concept of the Solar System, the invention of the telescope led to the discovery of further planets and moons. The principal component of the Solar System is the Sun, a G2 main-sequence star that contains 99. 86% of the known mass. The Suns four largest orbiting bodies, the giant planets, account for 99% of the mass, with Jupiter. The remaining objects of the Solar System together comprise less than 0. 002% of the Solar Systems total mass, most large objects in orbit around the Sun lie near the plane of Earths orbit, known as the ecliptic

Douglas DC-8
–
The Douglas DC-8 is a four-engine long-range narrow-body jet airliner built from 1958 to 1972 by the Douglas Aircraft Company. The DC-8s design allowed it a larger cargo capacity than the 707. After World War II Douglas had a position in the commercial aviation market. Boeing had pointed the way to the modern all-metal airliner in 1933 with its Model 247, Douglas produced a succession of piston-engined aircraft through the 1930s, 1940s, and 1950s. When de Havilland flew the first jet airliner, the Comet, in 1949, all three companies were working on a new generation of piston-engined designs, with an eye to turboprop conversion in the future. De Havillands pioneering Comet entered airline service in 1952, initially it was a success, but it was grounded after several fatal crashes in 1953 and 1954. The understanding of metal fatigue that the Comet investigation produced would play a part in the good safety record of later types like the DC-8. In 1952 Douglas remained the most successful of the aircraft manufacturers. They had almost 300 orders on hand for the piston-engined DC-6 and its successor, the DC-7, the Comet disasters, and the airlines subsequent lack of interest in jets, seemed to show the wisdom of their staying with propeller-driven aircraft. Boeing took the step of starting to plan a pure-jet airliner as early as 1949. Boeings military arm had gained experience with large, long-range jets through the B-47 Stratojet, with thousands of jet bombers on order or in service, Boeing had developed a close relationship with the US Air Forces Strategic Air Command. Boeing also supplied the SACs refueling aircraft, the piston-engined KC-97 Stratofreighters, the B-52, in particular, had to descend from its cruising altitude and then slow almost to stall speed to work with the KC-97. Believing that a requirement for a tanker was a certainty. As an airliner it would have seating capacity to the Comet. First presented in 1950 as the Model 473-60C, Boeing failed to any interest at the airlines. Boeing remained convinced that the project was worthwhile, and decided to press ahead with a prototype, after spending $16 million of their own money on construction, the Dash-80 rolled out on May 15,1954, and flew the next month. Boeings plans became obvious, despite the older model number. Douglas secretly began jet transport project studies in mid-1952

Lockheed F-104 Starfighter
–
The Lockheed F-104 Starfighter is a single-engine, supersonic interceptor aircraft which later became widely used as an attack aircraft. It was originally developed by Lockheed for the United States Air Force, but became used by US Allies around the world. One of the Century Series of fighter aircraft, it was operated by the air forces of more than a dozen nations from 1958 to 2004. Its design team was led by Kelly Johnson, who went on to lead or contribute to the development of the Lockheed SR-71 Blackbird, the F-104 set numerous world records, including both airspeed and altitude records. The poor safety record of the Starfighter also brought the aircraft into the public eye, Fighter ace Erich Hartmann was forced to retire from the Luftwaffe due to his outspoken opposition to selection of the F-104. The ultimate production version of the model was the F-104S, an all-weather interceptor designed by Aeritalia for the Italian Air Force. An advanced F-104 with a wing, known as the CL-1200 Lancer, was considered. In 2018 a privately owned Starfighter is scheduled to launch a group of small cubesat satellites into low orbit by carrying the rocket aloft. Clarence Kelly Johnson, the engineer at Lockheeds Skunk Works, visited Korea in December 1951. At the time, the U. S. pilots were confronting the MiG-15 with North American F-86 Sabres, the pilots requested a small and simple aircraft with excellent performance. Armed with this information, Johnson immediately started the design of such an aircraft on his return to the United States. In March, his team was assembled, they studied several designs, ranging from small designs at 8,000 lb. The engine chosen was the new General Electric J79, an engine of dramatically improved performance in comparison with contemporary designs, the small L-246 design powered by a single J79 remained essentially identical to the L-083 Starfighter as eventually delivered. The design was presented to the Air Force in November 1952, although all were interesting, Lockheed had an insurmountable lead, and was granted a development contract in March 1953 for two prototypes, these were given the designation XF-104. Work progressed quickly, with a ready for inspection at the end of April. Meanwhile, the J79 engine was not ready, both prototypes were designed to use the Wright J65 engine, a licensed-built version of the Armstrong Siddeley Sapphire. The first prototype was completed by early 1954 and first flew on 4 March at Edwards AFB, the total time from contract to first flight was less than a year. When the USAF revealed the existence of the XF-104, they gave a vague description of it

Lockheed A-12
–
The Lockheed A-12 was a reconnaissance aircraft built for the United States Central Intelligence Agency by Lockheeds Skunk Works, based on the designs of Clarence Kelly Johnson. The aircraft was designated A-12, the 12th in a series of internal design efforts for Archangel and it competed in the CIAs Oxcart program against the Convair Kingfish proposal in 1959, and won for a variety of reasons. CIAs representatives initially favored Convairs design for its smaller radar cross-section, the companies respective track records proved decisive. Convairs work on the B-58 had been plagued with delays and cost overruns, whereas Lockheed had produced the U-2 on time, in addition, it had experience running a “black” project. The A-12 was produced from 1962 to 1964, and operated from 1963 to 1968, the A-12s final mission was flown in May 1968, and the program and aircraft retired in June. The program was revealed in the mid-1990s. A CIA officer later wrote, OXCART was selected from a random list of codenames to designate this R&D, the aircraft itself came to be called that as well. The crews named the A-12 the Cygnus, suggested by pilot Jack Weeks to follow the Lockheed practice of naming aircraft after celestial bodies, under Project Gusto the designs were nicknamed Archangel, after the U-2 program, which had been known as Angel. As the aircraft designs evolved and configuration changes occurred, the internal Lockheed designation changed from Archangel-1 to Archangel-2 and these names for the evolving designs soon simply became known as A-1, A-2, etc. The CIA program to develop the aircraft to the U-2 was code-named Oxcart. These designs had reached the A-11 stage when the program was reviewed, the A-11 was competing against a Convair proposal called Kingfish, of roughly similar performance. However, the Kingfish included a number of features that reduced its radar cross-section. Lockheed responded with an update of the A-11, adding twin canted fins instead of a single right-angle one. On 26 January 1960, the CIA ordered 12 A-12 aircraft, because the A-12 was way ahead of its time, many new technologies had to be invented specifically for the Oxcart project, some still in use today. One of the biggest problems that engineers faced at that time was working with titanium, the Russians never had an inkling of how they were actually contributing to the creation of the airplane being rushed into construction to spy on their homeland. After development and production at the Skunk Works, in Burbank, California, on 25 April 1962 it was taken on its first flight with Lockheed test pilot Louis Schalk at the controls. The first official flight took place on 30 April and subsequent supersonic flight on 4 May 1962. The first five A-12s, in 1962, were flown with Pratt & Whitney J75 engines capable of 17,000 lbf thrust each

Bell X-1
–
Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 miles per hour in 1948. A derivative of this design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time. In 1942, the United Kingdoms Ministry of Aviation began a top secret project with Miles Aircraft to develop the worlds first aircraft capable of breaking the sound barrier. The project resulted in the development of the prototype turbojet-powered Miles M.52, designed to reach 1,000 miles per hour in level flight, and to climb to an altitude of 36,000 ft in 1 min 30 sec. By 1944, design of the M.52 was 90% complete, later that year, the Air Ministry signed an agreement with the United States to exchange high-speed research and data. Unknown to Miles, Bell had already started construction of a supersonic design of their own. Bell was battling the problem of control due to blanking the elevators. A variable-incidence tail appeared to be the most promising solution, the Miles, meanwhile, on 16 March 1945, the U. S. The X-1 was, in principle, a bullet with wings, its shape resembling a Browning. 50-caliber machine gun bullet. The shape was followed to the extent of seating its pilot behind a sloped, framed window inside a confined cockpit in the nose, after the rocket plane experienced compressibility problems during 1947, it was modified with a variable-incidence tailplane following technology transfer with the United Kingdom. The rocket engine was a design built by Reaction Motors. This rocket burned ethyl alcohol diluted with water with a liquid oxygen oxidizer and its thrust could be changed in 1,500 lbf increments by using just additional chambers. The fuel and oxygen tanks for the first two X-1 engines were pressurized with nitrogen, but the rest used gas-driven turbopumps, the all-important fuel turbopumps were necessary to increase the chamber pressure and thrust while making the engine lighter. The color of the X-1 #46-062, the Glamorous Glennis, is International Orange, not all subsequent models were painted with the same shade. Bell Aircraft chief test pilot Jack Woolams became the first person to fly the XS-1 and he made a glide-flight over Pinecastle Army Airfield, in Florida, on 25 January 1946. These were performed at Muroc Army Air Field near Palmdale, California, after Woolams death on 30 August 1946, Chalmers Slick Goodlin was the primary Bell Aircraft test pilot for the X-1-1. He made 26 successful flights in both X-1s from September 1946 through June 1947, the Army Air Forces was unhappy with the cautious pace of flight envelope expansion and Bell Aircrafts flight test contract for airplane #46-062 was terminated. The test program was acquired by the Army Air Force Flight Test Division on 24 June after months of negotiation, Goodlin had demanded a US$150,000 bonus for exceeding the speed of sound

The Right Stuff (film)
–
The Right Stuff stars Ed Harris, Scott Glenn, Sam Shepard, Fred Ward, Dennis Quaid and Barbara Hershey. Levon Helm is the narrator in the introduction and elsewhere in the film, in 2013 the film was selected for preservation in the United States National Film Registry by the Library of Congress as being culturally, historically, or aesthetically significant. In 1947, the Muroc Army Air Field in California has test pilots fly high-speed aircraft such as the rocket-powered Bell X-1, but they die as a result. After another pilot, Slick Goodlin, demands $150,000 to attempt to break the sound barrier, war hero Captain Chuck Yeager receives the chance to fly the X-1. While on a ride with his wife Glennis, Yeager collides with a tree branch and breaks his ribs. Worried that he not fly the mission, Yeager confides in friend. Six years later, Muroc, now Edwards Air Force Base, Yeager and friendly rival Scott Crossfield repeatedly break the others speed records. They often visit the Happy Bottom Riding Club run by Pancho Barnes, gordon Gordo Cooper, Virgil Gus Grissom and Donald Deke Slayton, captains of the United States Air Force, are among the pudknockers who hope to also prove that they have the Right Stuff. The tests are no secret, as the military soon recognizes that it needs good publicity for funding. Coopers wife, Trudy, and other wives are afraid of becoming widows, in 1957, the launch of the Russian Sputnik satellite alarms the United States government. Politicians such as Senator Lyndon B. Johnson and military leaders demand that NASA help America defeat the Russians in the new Space Race, the search for the first Americans in space excludes Yeager because he lacks a college degree. Although many early NASA rockets explode during launch, the ambitious astronauts all hope to be the first in space as part of Project Mercury. Although engineers see the men as passengers, the pilots insist that the Mercury spacecraft have a window, a hatch with explosive bolts, however, Russia beats them on April 12,1961 with the launch of Vostok 1 carrying Yuri Gagarin into space. The seven astronauts immediately decide to start the Mercury program, Shepard is the first American to reach space on the 15-minute sub-orbital flight of Mercury-Redstone 3 on May 5. After Grissoms similar flight of Mercury-Redstone 4 on July 21, the capsules hatch blows open, Grissom escapes, but the spacecraft, overweight with seawater, sinks. Many criticize Grissom for possibly panicking and opening the hatch prematurely, Glenn becomes the first American to orbit the Earth on Mercury-Atlas 6 on February 20,1962, surviving a possibly loose heat shield, and receives a ticker-tape parade. While testing the new Lockheed NF-104A, Yeager attempts to set a new record at the edge of space but is nearly killed in a high-speed ejection when his engine fails. Though seriously burned, after reaching the ground Yeager gathers up his parachute and walks to the ambulance, on May 15,1963, Cooper has a successful launch on Mercury-Atlas 9, ending the Mercury program

Wright Glider
–
The Wright brothers designed, built and flew a series of three manned gliders in 1900–1902 as they worked towards achieving powered flight. They also made preliminary tests with a kite in 1899, in 1911 Orville conducted tests with a much more sophisticated glider. Neither the kite nor any of the gliders was preserved, the 1899 kite, which Wilbur flew near his home in Dayton, Ohio had a wingspan of only 5 feet. The Wrights burned the craft along with trash in 1905. The 1900 Wright Glider was the brothers first to be capable of carrying a human and its overall structure was based on Octave Chanutes two-surface glider of 1896. Its wing airfoil was derived from Otto Lilienthals published tables of aerodynamic lift, the glider was designed with wing-warping capability for full-size testing of the concept first tried on the 1899 Wright Kite. The glider was first flown as a kite on October 5,1900 near Kitty Hawk. Next, Wilbur rode as pilot while men on the ground held tether ropes attached to the airborne craft, subsequently, Wilbur made about a dozen free flights on a single day, concluding the seasons test efforts. The brothers abandoned the glider when they broke camp on 23 October, the fabric covering of the wing components were given to the wife of helper Bill Tate, whose family Wilbur first stayed with at Kitty Hawk in 1900. Mrs. Tate allegedly used the material to make dresses for her daughters, the 1901 Wright Glider was the second of the brothers experimental gliders. They tested it over the Kill Devil Hills, four miles south of Kitty Hawk, the glider was similar to the 1900 version, but had larger wings. It first flew on July 27,1901, and was retired on August 17, during this time it made between 50 and 100 free flights, in addition to tethered flights as a kite. The wing ribs flexed under the weight of the pilot, distorting the airfoil shapes of the wings, the brothers fixed the trouble, but the wings still produced much less lift than expected, and wing-warping sometimes made the glider turn opposite the intended direction. After testing concluded, the brothers stored the glider in their camp shed, the shed and glider were badly damaged later by windstorms. The wing uprights were salvaged for the 1902 Glider, but the rest was abandoned, as a result of lift and drift measurements taken with the tethered glider, the brothers concluded that Lilienthals data were inaccurate. Upon returning to Dayton, they designed and built a wind tunnel to collect their own data. The 1902 Wright Glider was the third free-flight glider built by the brothers and this was their first glider to incorporate yaw control by use of a rear rudder, and its design led directly to the powered 1903 Wright Flyer. The brothers designed the 1902 glider during the winter of 1901/02, the wing design was based on data from extensive tests of miniature airfoils in their homemade wind tunnel

Velie Monocoupe
–
The Velie Monocoupe was an American general aviation aircraft manufactured from 1927-1929 by the Mono-Aircraft Corp, a division of Velie Motors Corporation. The Velie Monocoupe was a framed, doped fabric-covered monoplane. In an era of big, costly, lumbering, open-cockpit biplanes, in all there were 350 Velie Monocoupes produced under the approved type certificate number 22. Upon W. L. Velies death, his son had planned to continue production of the aircraft, the company, and design, survived, however. Mono Aircraft would continue to produce the Monocoupe, in various versions—ultimately changing its name to Monocoupe Corp, the company producing the Monocoupe line changed ownership and location several times from 1926 to the early 1950s. There is a Monocoupe on display at the California Science Center, on loan from the National Air, another example exists at Old Rhinebeck Aerodrome, and is being restored to airworthiness. Another in private hands in Texas has been restored and is flown regularly

Northrop T-38 Talon
–
The Northrop T-38 Talon is a two-seat, twin-engined supersonic jet trainer. It was the worlds first supersonic trainer and is also the most produced, the T-38 remains in service as of 2017 in several air forces. The United States Air Force operates the most T-38s, in addition to training USAF pilots, the T-38 is used by NASA. The U. S. Naval Test Pilot School is the principal US Navy operator, pilots of other NATO nations fly the T-38 in joint training programs with USAF pilots. As of 2015, the T-38 has been in service for over 50 years with its original operator, in 1952 Northrop began work on a fighter project, the Fang, with shoulder-mounted delta wing and a single engine. The proposed General Electric J79 engine, weighing two tons, meant the resulting aircraft would be large and expensive. Schmued and chief engineer Welko Gasich decided on a small twin-engine hot-rod fighter, Northrop began its N-156 project in 1954, aiming for a small supersonic fighter jet capable of operating from the US Navys escort carriers. In the mid-1950s the USAF issued a General Operating Requirement for a supersonic trainer, Northrop officials decided to adapt the N-156 to this competition. The only other candidate was the version of the North American F-100 Super Sabre. However, Northrop officials convincingly presented life-cycle cost comparisons which could not be ignored, the first flew on 10 March 1959. The type was adopted and the first production examples were delivered in 1961, officially entering service on 17 March that year. When production ended in 1972,1,187 T-38s had been built, since its introduction, it is estimated that some 50,000 military pilots have trained on this aircraft. The USAF remains one of the few armed flying forces using dedicated supersonic final trainers, as most, such as the US Navy, the T-38 is of conventional configuration, with a small, low, long-chord wing, a single vertical stabilizer, and tricycle undercarriage. The aircraft seats a student pilot and instructor in tandem, and has intakes for its two engines at the wing roots. Its nimble performance has earned it the nickname white rocket, in 1962 the T-38 set absolute time-to-climb records for 3,000,6,000,9,000 and 12,000 meters, beating the records for those altitudes set by the F-104 in December 1958. The wings of both the T-38 and the F-5 family use conventional skin over spar-rib structure, in 2015,504 T-38s were still operational with the USAF, with many more in operation around the world. Most of the USAF variant aircraft have been converted to the T-38C through an upgrade program. Improvements include the addition of a HUD, GPS, INS, most jets have also received PMP

Northrop F-20
–
The Northrop F-20 Tigershark was a privately financed light fighter, designed and built by Northrop. Compared with the F-5E, the F-20 was much faster, gained beyond-visual-range air-to-air capability, with these improved capabilities, the F-20 became competitive with contemporary fighter designs such as the General Dynamics F-16 Fighting Falcon, but was much less expensive to purchase and operate. Much of the F-20s development was carried out under a US Department of Defense project called FX, FX sought to develop fighters that would be capable in combat with the latest Soviet aircraft, but excluding sensitive front-line technologies used by the United States Air Forces own aircraft. The development program was abandoned in 1986 after three prototypes had been built and a partially completed. A number of designs were studied, including versions of the Lockheed F-104 Starfighter and Vought F-8 Crusader. On 23 April 1962, the United States Air Force informed the United States Secretary of Defense that the N-156F had been selected, under the designation F-5,847 F-5s of various early marks would be produced. As the Mikoyan-Gurevich MiG-21 became more common, the U. S. Air Force initiated the International Fighter Aircraft program to provide an equivalent to allies. The USAF desired a light fighter with competitive performance to the MiG, inexpensive when purchased in large numbers. Although numerous companies entered designs, Northrops existing F-5 put them in a leading position and they submitted an upgrade, the F-5E Tiger II, with the AN/APQ-153 radar and other changes to allow the AIM-9 Sidewinder missile to be fired from wing-tip rails. On 20 November 1970, Northrops entry was announced as the IFA winner, Northrop produced a total of 1,399 F-5E/F Tiger IIs by the time manufacturing ended in 1986. In the late 1970s, the Republic of China Air Force started looking for an aircraft to match improvements made in mainland Peoples Republic of China s air force. In particular, they wanted a capable of firing the AIM-7 Sparrow long-range missile. At the time, the US was in the process of opening up ties with the Peoples Republic of China after President Nixons famous visit in 1972, China considered US support of Taiwan against their interests, and the US State Department wanted to tread carefully. They blocked export of all of the AIM-7 capable aircraft, even otherwise outdated early models of the McDonnell Douglas F-4 Phantom II, the State Department suggested the Israeli IAI Kfir instead, however, it was rejected. Taiwan was already producing the F-5E under license, so the Department of Defense asked Northrop to study adding an AIM-7 capable radar to the Tiger II as an alternative and this effort became the first of several F-5G studies. In the spring of 1977, Jimmy Carters administration had announced a new military policy that limited sales of front line designs to countries within NATO, along with Australia. Carter stated at the time that the U. S. could not be both the champion of peace and the worlds leading supplier of the weapons of war. Previously, there was no coherent export policy, fueling concerns that the USs latest technologies might quickly end up in Soviet hands, South Koreas F-16 order was initially blocked under this policy, but later allowed in the context of strengthening relations

McDonnell Douglas F/A-18 Hornet
–
The McDonnell Douglas F/A-18 Hornet is a twin-engine supersonic, all-weather carrier-capable multirole combat jet, designed as both a fighter and attack aircraft. Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latters YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of other nations and, since 1986, by the U. S. Navys Flight Demonstration Squadron. The F/A-18 has a top speed of Mach 1.8 and it can carry a wide variety of bombs and missiles, including air-to-air and air-to-ground, supplemented by the 20-mm M61 Vulcan cannon. It is powered by two General Electric F404 turbofan engines, which give the aircraft a high thrust-to-weight ratio, the F/A-18 has excellent aerodynamic characteristics, primarily attributed to its leading edge extensions. The fighters primary missions are fighter escort, fleet air defense, Suppression of Enemy Air Defenses, air interdiction, close air support, the Hornet first saw combat action during the 1986 United States bombing of Libya and subsequently participated in the 1991 Gulf War and 2003 Iraq War. The F/A-18 Hornet provided the design for the Boeing F/A-18E/F Super Hornet, its larger. In August 1973, Congress mandated that the Navy pursue a lower-cost alternative to the F-14, grumman proposed a stripped F-14 designated the F-14X, while McDonnell Douglas proposed a naval variant of the F-15, but both were nearly as expensive as the F-14. That summer, Secretary of Defense Schlesinger ordered the Navy to evaluate the competitors in the Air Forces Lightweight Fighter program, the Air Force competition specified a day fighter with no strike capability. On 2 May 1975, the Navy announced its selection of the YF-17, since the LWF did not share the design requirements of the VFAX, the Navy asked McDonnell Douglas and Northrop to develop a new aircraft from the design and principles of the YF-17. On 1 March 1977, Secretary of the Navy W. Graham Claytor announced that the F-18 would be named Hornet. Northrop had partnered with McDonnell Douglas as a contractor on NACF to capitalize on the latters experience in building carrier aircraft. On the F-18, the two agreed to evenly split component manufacturing, with McDonnell Douglas conducting final assembly. McDonnell Douglas would build the wings, stabilators, and forward fuselage, while Northrop would build the center and aft fuselage and vertical stabilizers. McDonnell Douglas was the contractor for the naval versions. The F-18, initially known as McDonnell Douglas Model 267, was modified from the YF-17. For carrier operations, the airframe, undercarriage, and tailhook were strengthened, folding wings and catapult attachments were added, and the landing gear widened. To meet Navy range and reserves requirements, McDonnell increased fuel capacity by 4,460 pounds, by enlarging the dorsal spine, a snag was added to the wings leading edge and stabilators to prevent an Aeroelastic flutter discovered in the F-15 stabilator

Mercury-Redstone 2
–
Mercury-Redstone 2 was the penultimate test flight of the Mercury-Redstone Launch Vehicle prior to the first manned American space mission in Project Mercury. It was launched at 16,55 UTC on January 31,1961 from LC-5 at Cape Canaveral, Mercury spacecraft No.5 carried Ham the Chimp, a chimpanzee, on a suborbital flight, landing in the Atlantic Ocean 16 minutes and 39 seconds after launch. The previous Mercury-Redstone mission, MR-1A, flew a trajectory that was too steep with accelerations too high for a human passenger, MR-1A had climbed to its programmed apogee of about 130 miles and landed 235 miles downrange. Mercury-Redstone 2 would follow a more flattened trajectory and its planned flight path was an apogee of 115 miles and a range of 290 miles. The six chimps were trained in Mercury simulators for three weeks, the day before the flight, two chimps were chosen for the mission, one primary, Ham, and one backup, a female chimp named Minnie. The competition was fierce, but Ham was full of energy, Ham was named in honor of Holloman Aerospace Medical Center. Ham was from Cameroon, Africa, and was purchased by the USAF July 9,1959 and he was 3 years 8 months old at launch. At 12,53 UTC, January 31,1961, Ham was inserted into the spacecraft, the countdown was then delayed almost four hours because of a hot inverter, and several other minor problems. At 16,55 UTC the MR-2 lifted off, computers reported one minute after launch, the flight path angle was at least one degree too high and rising. At two minutes, the computers predicted a 17 g acceleration, at 2 minutes 17 seconds into the flight, the liquid oxygen supply was depleted. The closed-loop abort system sensed a change in engine chamber pressure when the LOX supply was depleted and fired the launch escape system, the abort signaled a Mayday message to the recovery forces. The high flight angle, and the abort, caused the maximum velocity of the spacecraft to be 7,540 ft/s instead of the planned 6,465 ft/s. The retrorockets had been jettisoned during the abort and therefore could not be used to slow down the spacecraft, all of this added up to an overshoot of the planned landing area by 130 miles and an apogee of 157 miles instead of 115 miles. Another problem occurred at 2 minutes and 18 seconds into the flight and this malfunction was traced later to the air inlet snorkel valve. Vibrations had loosened a pin in the valve and allowed the valve to open. Ham was safe in his own couch spacesuit and did not suffer any ill effects from the loss of cabin pressure and his couch spacesuit pressure remained normal, and suit temperature stayed well within the 60 to 80 degrees Fahrenheit optimum range. Because of over-acceleration of the vehicle and the boost from the escape rocket. At apogee Hams spacecraft was 48 miles farther downrange than planned, Ham was weightless for 6.6 minutes instead of the 4.9 minutes that were planned

Ham (chimpanzee)
–
Ham, also known as Ham the Chimp and Ham the Astrochimp, was a chimpanzee and the first hominid launched into space, on 31 January 1961, as part of Americas space program. Hams name is an acronym for the lab which prepared him for his historic mission — the Holloman Aerospace Medical Center, Ham was born in 1956 or 1957 in Cameroon, captured by animal trappers and sent to Rare Bird Farm in Miami, Florida. He was purchased by the United States Air Force and brought to Holloman Air Force Base in 1959, there were originally 40 chimpanzee flight candidates at Holloman. After evaluation, the number of candidates was reduced to 18, then to 6, officially, Ham was known as No.65 before his flight, and only renamed Ham upon his successful return to Earth. This was reportedly because officials did not want the bad press that would come from the death of a named chimpanzee if the mission were a failure, among his handlers, No.65 had been known as Chop Chop Chang. On January 31,1961, Ham was secured in a Project Mercury mission labeled MR-2 and launched from Cape Canaveral, Florida, Ham had his vital signs and tasks monitored using computers on Earth. The capsule suffered a loss of pressure during the flight. Hams lever-pushing performance in space was only a fraction of a slower than on Earth. Hams capsule splashed down in the Atlantic Ocean and was recovered by a rescue ship later that day and he only suffered a bruised nose. His flight was 16 minutes and 39 seconds long, after the flight, Ham lived for 17 years in the National Zoo in Washington, D. C. before joining a small group of captive chimps at North Carolina Zoo. After his death in 1983, Hams body was turned over to the Armed Forces Institute of Pathology for necropsy, following the necropsy, the plan was to have him stuffed and placed on display at the Smithsonian, following Soviet precedent with pioneering space dogs Belka and Strelka. However, this plan was abandoned after a public reaction. Hams remains, minus the skeleton, were buried at the International Space Hall of Fame in Alamogordo, colonel John Stapp gave the eulogy at the memorial service. The skeleton is held in the collection of the National Museum of Health, Hams backup, Minnie, was the only female chimpanzee trained for the Mercury program. She was the last surviving astro-chimpanzee and died at age 41 on March 14,1998, the 1961 animated television series Tales of the Wizard of Oz featured two flying monkeys named Ham and Baker. The film mentions that the chimpanzee became the first American to cross into outer space, a 2001 film titled Race to Space, was a fictionalized version of Hams story about sending chimpanzees to space. The chimpanzee in the movie was named Mac, in series 1, episode 1 of The Ricky Gervais Show, Karl Pilkington tells his version of Hams mission in his Monkey News segment. The 2006 song Monkey 61 by Irish band Bell X1 was based on Ham the Chimp, in 2007, a French documentary was made in association with Animal Planet called Ham - Astrochimp #65, which tells the story of Ham as witnessed by Jeff

Hominidae
–
Several revisions in classifying the great apes have caused the use of the term hominid to vary over time. Its original meaning referred only to humans and their closest non-extant relatives and that restrictive meaning has now been largely assumed by the term hominin, which comprises all members of the human clade after the split from the chimpanzees. The current, 21st-century meaning of hominid includes all the great apes including humans, the most recent common ancestor of all Hominidae lived roughly 14 million years ago, when the ancestors of the orangutans speciated from the ancestral line of the other three genera. Those ancestors of the family Hominidae had already speciated from the family Hylobatidae, in the early Miocene, about 22 million years ago, there were many species of arboreally adapted primitive catarrhines from East Africa, the variety suggests a long history of prior diversification. Fossils at 20 million years ago include fragments attributed to Victoriapithecus, the most recent of these far-flung Miocene apes is Oreopithecus, from the fossil-rich coal beds in northern Italy and dated to 9 million years ago. Species close to the last common ancestor of gorillas, chimpanzees and humans may be represented by Nakalipithecus fossils found in Kenya and Ouranopithecus found in Greece. Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the split off from the line leading to the humans. Human DNA is approximately 98. 4% identical to that of chimpanzees when comparing single nucleotide polymorphisms, the earliest fossils argued by some to belong to the human lineage are Sahelanthropus tchadensis and Orrorin tugenensis, followed by Ardipithecus, with species Ar. kadabba and Ar. ramidus. The classification of the apes has been revised several times in the last few decades. The original meaning of the referred to only humans and their closest relatives—what is now the modern meaning of the term hominin. And the meaning of the taxon Hominidae changed gradually, leading to a different usage of hominid that today all the great apes including humans. A hominid is a member of the family Hominidae, the apes, orangutans, gorillas, chimpanzees. A hominine is a member of the subfamily Homininae, gorillas, chimpanzees, a hominin is a member of the tribe Hominini, Chimpanzees and humans. A homininan is a member of the subtribe Hominina of the tribe Hominini, a human is a member of the genus Homo, of which Homo sapiens is the only extant species, and within that Homo sapiens sapiens is the only surviving subspecies. For each clade it is indicated approximately when newer extant clades emerged, some texts will refer to Homonini as the Hominina branch. Many scientists, including paleoanthropologists, continue to use the term hominid to mean humans, as mentioned, Hominidae was originally the name given to the family of humans and their close relatives, with the other great apes all being placed in a separate family, the Pongidae. However, that eventually made Pongidae paraphyletic because at least one great ape species proved to be more closely related to humans than to other great apes. Most taxonomists today encourage monophyletic groups—this would require, in this case, thus, many biologists now assign Pongo to the family Hominidae

Gemini 11
–
Gemini 11 ) was the ninth manned spaceflight mission of NASAs Project Gemini, which flew from September 12 to 15,1966. It was the 17th manned American flight and the 25th spaceflight to that time, astronauts Charles Pete Conrad, Jr. and Richard F. Gordon Jr. Gordon also performed two extra-vehicular activities for a total of 2 hours and 41 minutes. Williams, Jr. John W. Young Alan L. Bean Mass,8,374 pounds Highest orbit and this would simulate a Lunar Module rendezvous with the Command/Service Module after a lunar landing. Use the Agena rocket engine to put the craft in a high-apogee elliptical orbit. Demonstrate passive attitude stabilization of the two connected by a tether, and create artificial gravity by spinning the combined craft. Perform a computer-controlled atmospheric reentry to a precision splashdown point, Gemini 11 used the rocket on its Agena target vehicle to raise its apogee to 850 miles, the highest Earth orbit ever reached by a manned spacecraft. The perigee was 179 miles, and maximum velocity was 17,967 miles per hour, the apogee record stands as of March 2016, even though men have achieved greater distances from Earth by flying to the Moon in the Apollo program. The maximum operational altitude of the Space Shuttle was lower, at 600 miles, the crew docked and undocked four times, and still had sufficient Gemini maneuvering fuel for an unplanned fifth rendezvous. They did not remain in the orbit, but changed it back to a near-circular one at 184 miles. Gordons first EVA, planned to last for two hours, involved fastening a 100-foot tether, stored in the Agenas docking collar, to the Geminis docking bar for the passive stabilization experiment, the passive stabilization experiment proved to be a bit troublesome. Conrad and Gordon separated the craft in a position, but found that the tether would not be kept taut simply by the Earths gravity gradient. However, they were able to generate an amount of artificial gravity, about 0.00015 g. Gordon successfully performed a second EVA standing up with his head and shoulders out of the hatch to photograph the Earth, clouds and this was not tiring, and lasted more than two hours.

Viking program
–
The Viking program consisted of a pair of American space probes sent to Mars, Viking 1 and Viking 2. Each spacecraft was composed of two parts, an orbiter designed to photograph the surface of Mars from orbit. The orbiters also served as communication relays for the landers once they touched down, the Viking program grew from NASAs earlier, even more ambitious, Voyager Mars program, which was not related to the successful Voyager deep space probes of the late 1970s. Viking 1 was launched on August 20,1975, and the craft, Viking 2, was launched on September 9,1975. Viking 1 entered Mars orbit on June 19,1976, with Viking 2 following suit on August 7, the Viking 1 lander touched down on the surface of Mars on July 20,1976, and was joined by the Viking 2 lander on September 3. The orbiters continued imaging and performing other operations from orbit while the landers deployed instruments on the surface. The project cost roughly 1 billion USD in 1970s dollars, equivalent to about 11 billion USD in 2016 dollars and it was highly successful and formed most of the body of knowledge about Mars through the late 1990s and early 2000s. Each orbiter, based on the earlier Mariner 9 spacecraft, was an octagon approximately 2.5 m across, the fully fueled orbiter-lander pair had a mass of 3527 kg. After separation and landing, the lander had a mass of about 600 kg, the total launch mass was 2328 kg, of which 1445 kg were propellant and attitude control gas. The eight faces of the structure were 0.4572 m high and were alternately 1.397 and 0.508 m wide. The overall height was 3.29 m from the attachment points on the bottom to the launch vehicle attachment points on top. There were 16 modular compartments,3 on each of the 4 long faces, four solar panel wings extended from the axis of the orbiter, the distance from tip to tip of two oppositely extended solar panels was 9.75 m. The main propulsion unit was mounted above the orbiter bus, propulsion was furnished by a bipropellant liquid-fueled rocket engine which could be gimballed up to 9 degrees. The engine was capable of 1,323 N thrust, translating to a change in velocity of 1480 m/s, attitude control was achieved by 12 small compressed-nitrogen jets. An acquisition Sun sensor, a cruise Sun sensor, a Canopus star tracker, two accelerometers were also on board. Communications were accomplished through a 20 W S-band transmitter and two 20 W TWTAs, an X band downlink was also added specifically for radio science and to conduct communications experiments. A two-axis steerable parabolic dish antenna with a diameter of approximately 1.5 m was attached at one edge of the base. Two tape recorders were each capable of storing 1280 megabits, a 381-MHz relay radio was also available

Pioneer 10
–
Pioneer 10 is an American space probe, launched in 1972 and weighing 258 kilograms, that completed the first mission to the planet Jupiter. Thereafter, Pioneer 10 became the first spacecraft to escape velocity from the Solar System. This space exploration project was conducted by the NASA Ames Research Center in California, Pioneer 10 was assembled around a hexagonal bus with a 2.74 meters diameter parabolic dish high-gain antenna, and the spacecraft was spin stabilized around the axis of the antenna. Its electric power was supplied by four radioisotope thermoelectric generators that provided a combined 155 watts at launch and it was launched on March 2,1972, by an Atlas-Centaur expendable vehicle from Cape Canaveral, Florida. Between July 15,1972, and February 15,1973, photography of Jupiter began November 6,1973, at a range of 25,000,000 kilometers, and a total of about 500 images were transmitted. The closest approach to the planet was on December 4,1973, radio communications were lost with Pioneer 10 on January 23,2003, because of the loss of electric power for its radio transmitter, with the probe at a distance of 12 billion kilometers from Earth. An advocacy group named the Outer Space Panel and chaired by American space scientist James A. Van Allen, NASA Goddard Spaceflight Center put together a proposal for a pair of Galactic Jupiter Probes that would pass through the asteroid belt and visit Jupiter. These were to be launched in 1972 and 1973 during favorable windows that occurred only a few weeks every 13 months, Launch during other time intervals would have been more costly in terms of propellant requirements. Approved by NASA in February 1969, the spacecraft were designated Pioneer F and Pioneer G before launch, later they were named Pioneer 10. They formed part of the Pioneer program, a series of United States unmanned space missions launched between 1958 and 1978 and this model was the first in the series to be designed for exploring the outer Solar System. More than 150 scientific experiments were proposed for the missions, the experiments to be carried on the spacecraft were selected in a series of planning sessions during the 1960s, then were finalized by early 1970. NASA Ames Research Center, rather than Goddard, was selected to manage the project as part of the Pioneer program, the Ames Research Center, under the direction of Charles F. Hall, was chosen because of its previous experience with spin-stabilized spacecraft. The requirements called for a small, lightweight spacecraft which was magnetically clean and it was to use spacecraft modules that had already been proven in the Pioneer 6 through 9 missions. In February 1970, Ames awarded a combined $380 million contract to TRW for building both of the Pioneer 10 and 11 vehicles, bypassing the usual bidding process to save time, B. J. OBrien and Herb Lassen led the TRW team that assembled the spacecraft. Design and construction of the spacecraft required an estimated 25 million man-hours, to meet the schedule, the first launch would need to take place between February 29 and March 17 so that it could arrive at Jupiter in November 1974. The encounter trajectory for Pioneer 10 was selected to maximize the information returned about the environment around Jupiter. It would come within three times the radius of the planet, which was thought to be the closest it could approach. The trajectory chosen would give the spacecraft a good view of the sunlit side, the Pioneer 10 bus measured 36 centimeters deep and with six 76-centimeter long panels forming the hexagonal structure

Mariner IV
–
Mariner 4 was the fourth in a series of spacecraft intended for planetary exploration in a flyby mode. It was designed to conduct closeup scientific observations of Mars and to transmit these observations to Earth, launched on November 28,1964, Mariner 4 performed the first successful flyby of the planet Mars, returning the first pictures of the Martian surface. It captured the first images of another planet ever returned from space, their depiction of a cratered. On December 21,1967 communications with Mariner 4 were terminated, the Mariner 4 spacecraft consisted of an octagonal magnesium frame,127 cm across a diagonal and 45.7 cm high. Four solar panels were attached to the top of the frame with a span of 6.88 meters. A116.8 cm diameter parabolic antenna was mounted at the top of the frame as well. An omnidirectional low-gain antenna was mounted on a seven foot, four inch tall mast next to the high-gain antenna, the overall height of the spacecraft was 2.89 meters. The octagonal frame housed the equipment, cabling, midcourse propulsion system. A trapped radiation detector, mounted on the body with counter-axes pointing 70° and 135° from the direction, to measure the intensity. A cosmic ray telescope, mounted inside the body pointing in direction, to measure the direction and energy spectrum of protons. A solar plasma probe, mounted on the body pointing 10° from the solar direction, a cosmic dust detector, mounted on the body with microphone plate approximately perpendicular to the plane of orbit, to measure the momentum, distribution, density, and direction of cosmic dust. A television camera, mounted on a platform at the bottom center of the spacecraft. This subsystem consisted of 4 parts, a Cassegrain telescope with a 1. 05° by 1. 05° field of view, a rechargeable 1200 W·h silver-zinc battery was also used for maneuvers and backup. Monopropellant hydrazine was used for propulsion, via a four-jet vane vector control motor, with 222-newton thrust, the space probes attitude control was provided by 12 cold nitrogen gas jets mounted on the ends of the solar panels and three gyros. Solar pressure vanes, each with an area of 0.65 square meter, were attached to the tips of the solar panels. Positional information was provided by four Sun sensors, and a sensor for either the Earth, Mars, or the star Canopus, during this flight, both the Earth and Mars would be too dim to lock onto. Another bright source at an angle away from the Sun was needed. Subsequently, Canopus was used as a point in many following missions

Pioneer Venus project
–
The Pioneer Venus project was part of the Pioneer program consisting of two spacecraft, the Pioneer Venus Orbiter and the Pioneer Venus Multiprobe, launched to Venus in 1978. The program was managed by NASAs Ames Research Center, the Pioneer Venus Orbiter entered orbit around Venus on December 4,1978, and performed observations to characterize the atmosphere and surface of Venus. It continued to transmit data until October 1992, the Pioneer Venus Multiprobe deployed four small probes into the Venusian atmosphere on December 9,1978. All four probes transmitted data throughout their descent to the surface, one probe survived landing and transmitted data from the surface for over an hour. The Pioneer mission consisted of two components, launched separately, an orbiter and a multiprobe, the orbiter was launched on 20 May 1978 with an Atlas-Centaur rocket. The orbiters mass was 517 kg, the Pioneer Venus Orbiter was inserted into an elliptical orbit around Venus on December 4,1978. The Pioneer Venus Multiprobe was launched on August 8,1978 on an Atlas-Centaur rocket and it consisted of a 290 kg bus which carried one large and three small atmospheric probes. The large probe was released on November 16,1978 and the three small probes on November 20, all four probes entered the Venus atmosphere on December 9, followed by the bus. The Pioneer Venus large probe was about 1.5 m in diameter, after deceleration from initial atmospheric entry at about 11.5 km/s, a parachute was deployed at 47 km altitude.8 m in diameter and 90 kg each small probe. The small probes were each targeted at different parts of the planet, They had no parachutes, the Pioneer Venus bus also carried two experiments, a neutral mass spectrometer and an ion mass spectrometer to study the composition of the atmosphere. With no heat shield or parachute, the bus made measurements only to about 110 km altitude before burning up, Pioneer Venus specifications at NASA The Pioneer Venus Orbiter,11 years of data. Results published in May 1,1990

Terracotta
–
Terracotta, terra cotta or terra-cotta, a type of earthenware, is a clay-based unglazed or glazed ceramic, where the fired body is porous. The term is used to refer to the natural, brownish orange color, of most terracotta. This article covers the senses of terracotta as a medium in sculpture, as in the Terracotta Army and Greek terracotta figurines, asian and European sculpture in porcelain is not covered. Glazed architectural terracotta and its version as exterior surfaces for buildings were used in Asia for some centuries before becoming popular in the West in the 19th century. In archaeology and art history, terracotta is used to describe objects such as figurines not made on a potters wheel. An appropriate refined clay is formed to the desired shape, after drying it is placed in a kiln or atop combustible material in a pit, and then fired. The typical firing temperature is around 1,000 °C, though it may be as low as 600 °C in historic and archaeological examples. In some contexts, such as Roman figurines, white-colored terracotta is known as pipeclay, as such clays were later preferred for tobacco pipes, fired terracotta is not watertight, but surface-burnishing the body before firing can decrease its porousness and a layer of glaze can make it watertight. It is suitable for use below ground to carry pressurized water, for garden pots or building decoration in many environments, most other uses, such as for tableware, sanitary piping, or building decoration in freezing environments, require the material to be glazed. Terracotta, if uncracked, will ring if lightly struck, painted terracotta is typically first covered with a thin coat of gesso, then painted. It has been widely used but the paint is only suitable for indoor positions and is much less durable than fired colors in or under a ceramic glaze. Terracotta sculpture was rarely left in its raw fired state in the West until the 18th century. Terracotta/earthenware was the known type of ceramic produced by Western and pre-Columbian people until the 14th century. Terracotta has been used throughout history for sculpture and pottery as well as for bricks, in ancient times, the first clay sculptures were dried in the sun after being formed. They were later placed in the ashes of open hearths to harden, however, only after firing to high temperature would it be classed as a ceramic material. Terracotta female figurines were uncovered by archaeologists in excavations of Mohenjo-daro, along with phallus-shaped stones, these suggest some sort of fertility cult and a belief in a mother goddess. The Burney Relief is a terracotta plaque from Ancient Mesopotamia of about 1950 BC. In Mesoamerica, the majority of Olmec figurines were in terracotta

Ranch
–
A ranch is an area of land, including various structures, given primarily to the practice of ranching, the practice of raising grazing livestock such as cattle or sheep for meat or wool. The word most often applies to livestock-raising operations in Mexico, the Western United States and Canada, people who own or operate a ranch are called ranchers, cattlemen, or stockgrowers. Ranching is also a used to raise less common livestock such as elk, American bison or even ostrich, emu. Ranches generally consist of areas, but may be of nearly any size. In the western United States, many ranches are a combination of owned land supplemented by grazing leases on land under the control of the federal Bureau of Land Management. If the ranch includes arable or irrigated land, the ranch may also engage in an amount of farming, raising crops for feeding the animals, such as hay. Ranches that cater exclusively to tourists are called guest ranches or, colloquially, most working ranches do not cater to guests, though they may allow private hunters or outfitters onto their property to hunt native wildlife. Ranching is part of the iconography of the Wild West as seen in Western movies, the person who owns and manages the operation of a ranch is usually called a rancher, but the terms cattleman, stockgrower, or stockman are also sometimes used. If this individual in charge of management is an employee of the actual owner. A rancher who primarily raises young stock sometimes is called an operator or a cow-calf man. This person is usually the owner, though in cases, particularly where there is absentee ownership. The people who are employees of the rancher and involved in handling livestock are called a number of terms, including cowhand, ranch hand, people exclusively involved with handling horses are sometimes called wranglers. Ranching and the tradition originated in Spain, out of the necessity to handle large herds of grazing animals on dry land from horseback. During the Reconquista, members of the Spanish nobility and various military orders received large land grants that the Kingdom of Castile had conquered from the Moors and these landowners were to defend the lands put into their control and could use them for earning revenue. When the Conquistadors came to the Americas in the 16th century, followed by settlers, they brought their cattle, huge land grants by the Spanish government, part of the hacienda system, allowed large numbers of animals to roam freely over vast areas. A number of different traditions developed, often related to the location in Spain from which a settlement originated. For example, many of the traditions of the Jalisco charros in central Mexico come from the Salamanca charros of Castile, however, there were cattle on the eastern seaboard. Deep Hollow Ranch,110 miles east of New York City in Montauk, New York, claims to be the first ranch in the United States, the prairie and desert lands of what today is Mexico and the western United States were well-suited to open range grazing
