A space station known as an orbital station or an orbital space station, is a spacecraft capable of supporting a human crew in orbit for an extended period of time that lacks major propulsion or landing systems. Stations must have docking ports to allow other spacecraft to dock to transfer crew and supplies; the purpose of maintaining an orbital outpost varies depending on the program. Space stations have most been launched for scientific purposes, but military launches have occurred; as of 2019, one operational and permanently inhabited space station is in low Earth orbit: the International Space Station, used to study the effects of long-term space flight on the human body as well as to provide a location to conduct a greater number and length of scientific studies than is possible on other space vehicles. China, India and the U. S. as well as Bigelow Aerospace and Axiom Space, are all planning other stations for the coming decades. The first mention of anything resembling a space station occurred in Edward Everett Hale's 1869 "The Brick Moon".

The first to give serious, scientifically grounded consideration to space stations were Konstantin Tsiolkovsky and Hermann Oberth about two decades apart in the early 20th century. In 1929 Herman Potočnik's The Problem of Space Travel was published, the first to envision a "rotating wheel" space station to create artificial gravity. Conceptualized during the Second World War, the "sun gun" was a theoretical orbital weapon orbiting Earth at a height of 8,200 kilometres. No further research was conducted. In 1951, Wernher von Braun published a concept for a rotating wheel space station in Collier's Weekly, referencing Potočnik's idea. However, development of a rotating station was never begun in the 20th century. During the latter half of the 20th century, the Soviet Union developed and launched the world's first space station, Salyut 1; the Almaz and Salyut series were joined by Skylab and Tiangong-1 and Tiangong-2. The hardware developed during the initial Soviet efforts remains in use, with evolved variants a considerable part of the ISS space station orbiting today.

Each crew member stays aboard the station for weeks or months, but more than a year. Starting with the ill-fated flight of the Soyuz 11 crew to Salyut 1, all recent human spaceflight duration records have been set aboard space stations; the duration record for a single spaceflight is 437.75 days, set by Valeri Polyakov aboard Mir from 1994 to 1995. As of 2016, four cosmonauts have completed single missions of over a year, all aboard Mir; the last military-use space station was the Soviet Salyut 5, launched under the Almaz program and orbited between 1976 and 1977. Early stations were monolithic designs that were constructed and launched in one piece containing all their supplies and experimental equipment. A crew would be launched to join the station and perform research. After the supplies had been used up, the station was abandoned; the first space station was Salyut 1, launched by the Soviet Union on April 19, 1971. The earlier Soviet stations were all designated "Salyut", but among these there were two distinct types: civilian and military.

The military stations, Salyut 2, Salyut 3, Salyut 5, were known as Almaz stations. The civilian stations Salyut 6 and Salyut 7 were built with two docking ports, which allowed a second crew to visit, bringing a new spacecraft with them; this allowed for a crew to man the station continually. The American Skylab was equipped with two docking ports, like second-generation stations, but the extra port was never utilized; the presence of a second port on the new stations allowed Progress supply vehicles to be docked to the station, meaning that fresh supplies could be brought to aid long-duration missions. This concept was expanded on Salyut 7, which "hard docked" with a TKS tug shortly before it was abandoned; the Salyuts may reasonably be seen as a transition between the two groups. Unlike previous stations, the Soviet space station Mir had a modular design; this method allows for greater flexibility in operation, as well as removing the need for a single immensely powerful launch vehicle. Modular stations are designed from the outset to have their supplies provided by logistical support craft, which allows for a longer lifetime at the cost of requiring regular support launches.

Modules are still being developed based on the design and capabilities of Mir. China's first space laboratory, Tiangong-1 was launched in September 2011; the uncrewed Shenzhou 8 successfully performed an automatic rendezvous and docking in November 2011. The crewed Shenzhou 9 docked with Tiangong-1 in June 2012, the crewed Shenzhou 10 in 2013. A second space laboratory Tiangong-2 was launched in September 2016, while a plan for Tiangong-3 was merged with Tiangong-2. In May 2017, China informed the United Nations Office for Outer Space Affairs that Tiangong-1's altitude was decaying and that it would soon reenter the atmosphere and break up; the reentry was projected to occur in late March or early April 2018. According to the China Manned Space Engineering Office, Tiangong-1 reentered over the South Pacific Ocean, northwest of Tahiti, on 2 April 2018 at 00:15 UTC. In July 2019 the China Manned Space Engineering Office announced that it was planning to deorbit Tiangong-2 in the near future, but no specific date was given.

The station subsequently made a controlled reentry on 19 July and burned up over the South Pacif

Ras Siyyan or Ras Siyan is a peninsula in the Obock Region of Djibouti, on the Bab-el-Mandeb strait, about 20 km southwest of Perim Island. The peninsula consists of a reddish volcanic hill about 1.2 by 0.5 km and 138 m high, connected towards to the mainland by a low sandy strip that stretches south by about 5 km while widening from 500 to 800 m. The Ras Siyyan volcano is inactive but young, having erupted through a 21,000-year-old coral reef formation. To the west of Ras Siyyan there is a shallow marshy bay or lagoon, about 2.5 km wide, protected on the north side by shallow coral banks. The bay is fringed in spite of the little input of freshwater. Abundant sea grasses form large beds in the bay, Sharks breed there in October. An isolated white rock, Rocher Siyyan, lies in the bay about 800 m southwest of the volcanic hill; the hill of Ras Siyyan is sometimes considered the seventh of the Seven Brothers islands.

The Attalla Downtown Historic District is a historic district in Attalla, Alabama. The city was founded in 1870 along the Chattanooga Railroad, it developed into a major iron ore export hub. After fires in 1887 and 1891, most of the frame buildings downtown were replaced with brick structures; the oldest buildings in the district, which date from the 1880s and 1890s, are built in Folk Victorian styles, with corbelled cornices and other decorative elements. Buildings are in more plain Commercial Brick styles, while others were built in more academic styles, including the Art Moderne Etowah Theatre and the Colonial Revival Post Office building; the district was listed on the Alabama Register of Landmarks and Heritage in 2011 and the National Register of Historic Places in 2013

Pinguk River is a waterway located on the Seward Peninsula in the U. S. state of Alaska. The river runs in a northwesterly direction for 34 miles and flows into the Arctic Lagoon about 30 miles northeast of Cape Prince of Wales; the river flows over a length of 34 miles in a zigzag course. Before the river joins the sea, at about 10 miles upstream it forms two branches; the York River rises on the eastern flanks of Brooks Mountain, the highest point in the York Mountains, in the central part of the Teller Quadrangle. It flows in a northeast direction and confluences with the McKillop River; the river flows through a valley formation of 200–300 feet width. The geological formation reported in the valley consists of slate and is exposed in some stretches of the river; the river bed is strewn with gravel and pebbles of limestone. The gravel and pebbles have their origin in the Kuzitrin series; the limestones are derivatives of the Port Clarence limestones. The McKillop branch has its source in the limestone hills, which are an eastern arm of the York Mountains.

The geological formation in this river valley is made up only of limestones and belongs to the Port Clarence formation. The York River, a branch of the Pinguk River, which rises in the Brooks Mountain, is reported to be rich in tin deposits in its head reaches in the mountains; the river bed is strewn with pebbles and granites, an indication that tin was embedded in granite contact zone in granite formations in the hills. However, no gold has been found in this river valley; this article incorporates text from a publication now in the public domain: A. J.
