Voyager 2

Voyager 2 is a space probe launched by NASA on August 20, 1977, to study the outer planets. Part of the Voyager program, it was launched 16 days before its twin, Voyager 1, on a trajectory that took longer to reach Jupiter and Saturn but enabled further encounters with Uranus and Neptune, it is the only spacecraft to have visited either of these two ice giant planets. Voyager 2 is the fourth of five spacecraft to achieve the Solar escape velocity, which will allow it to leave the Solar System, its primary mission ended with the exploration of the Neptunian system on October 2, 1989, after having visited the Uranian system in 1986, the Saturnian system in 1981, the Jovian system in 1979. Voyager 2 is now in its extended mission to study the outer reaches of the Solar System and has been operating for 42 years, 6 months and 8 days as of February 29, 2020, it remains in contact through the NASA Deep Space Network. On November 5, 2018, at a distance of 122 AU from the Sun, moving at a velocity of 15.341 km/s relative to the Sun, Voyager 2 left the heliosphere, entered the interstellar medium, a region of outer space beyond the influence of the Solar System, joining Voyager 1 which had reached the interstellar medium in 2012.

Voyager 2 has begun to provide the first direct measurements of the density and temperature of the interstellar plasma. In the early space age, it was realized that a periodic alignment of the outer planets would occur in the late 1970s and enable a single probe to visit Jupiter, Saturn and Neptune by taking advantage of the then-new technique of gravity assists. NASA began work on a Grand Tour, which evolved into a massive project involving two groups of two probes each, with one group visiting Jupiter and Pluto and the other Jupiter and Neptune; the spacecraft would be designed with redundant systems to ensure survival through the entire tour. By 1972 the mission was scaled back and replaced with two Mariner-derived spacecraft, the Mariner Jupiter-Saturn probes. To keep apparent lifetime program costs low, the mission would include only flybys of Jupiter and Saturn, but keep the Grand Tour option open; as the program progressed, the name was changed to Voyager. The primary mission of Voyager 1 was to explore Jupiter and Saturn's moon, Titan.

Voyager 2 was to explore Jupiter and Saturn, but on a trajectory that would have the option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1. Upon successful completion of Voyager 1's objectives, Voyager 2 would get a mission extension to send the probe on towards Uranus and Neptune. Constructed by the Jet Propulsion Laboratory, Voyager 2 included 16 hydrazine thrusters, three-axis stabilization and celestial referencing instruments to maintain pointing of the high-gain antenna toward Earth. Collectively these instruments are part of the Attitude and Articulation Control Subsystem along with redundant units of most instruments and 8 backup thrusters; the spacecraft included 11 scientific instruments to study celestial objects as it traveled through space. Built with the intent for eventual interstellar travel, Voyager 2 included a large, 3.7 m parabolic, high-gain antenna to transceive data via the Deep Space Network on the Earth. Communications are conducted over the S-band and X-band providing data rates as high as 115.2 kilobits per second at the distance of Jupiter, ever-decreasing as the distance increased, because of the inverse-square law.

When the spacecraft is unable to communicate with Earth, the Digital Tape Recorder can record about 64 megabytes of data for transmission at another time. Voyager 2 is equipped with 3 Multihundred-Watt radioisotope thermoelectric generators; each RTG includes 24 pressed plutonium oxide spheres, provided enough heat to generate 157 W of electrical power at launch. Collectively, the RTGs supplied the spacecraft with 470 watts at launch, will allow operations to continue until at least 2020; because of the energy required to achieve a Jupiter trajectory boost with an 1,819-pound payload, the spacecraft included a propulsion module made of a 2,476-pound solid-rocket motor and eight hydrazine monopropellant rocket engines, four providing pitch and yaw attitude control, four for roll control. The propulsion module was jettisoned shortly after the successful Jupiter burn. Sixteen hydrazine MR-103 thrusters on the mission module provide attitude control. Four are used to execute trajectory correction maneuvers.

Only one branch of attitude control thrusters is needed at any time. Thrusters are supplied by a single 28-inch diameter spherical titanium tank, it contained 230 pounds of hydrazine at launch, providing enough fuel until 2034. For more details on the Voyager space probes' identical instrument packages, see the separate article on the overall Voyager Program; the Voyager 2 probe was launched on August 20, 1977, by NASA from Space Launch Complex 41 at Cape Canaveral, aboard a Titan IIIE/Centaur launch vehicle. Two weeks the twin Voyager 1 probe was launched on September 5, 1977. However, Voyager 1 reached both Jupiter and Saturn sooner, as Voyager 2 had been launched into a longer, more circular trajectory. Voyager 1's initial orbit had an aphelion of 8.9 AU, just a little short of Saturn's orbit of 9.5 AU. Voyager 2's initial orbit had an aphelion of 6.2 AU, well short of Saturn's orbit. In April 1978, a complication arose when no commands were transmitted to Voyager 2 for a period

High Sheriff of Somerset

The Office of High Sheriff of Somerset, until 1974 called Sheriff of Somerset, is an ancient shrievalty, in existence for over one thousand years. On 1 April 1974, under the provisions of the Local Government Act 1972, the office of Sheriff of Somerset was retitled as High Sheriff of Somerset; the position of Sheriff was once a powerful one, the holders being responsible for collecting taxes and enforcing law and order in Somerset, a county in South West England. In modern times the sheriff has become a ceremonial officer of the Crown, attending or presiding over many public events; until 1567 the Sheriff of Somerset was Sheriff of Dorset. In England and Northern Ireland the high sheriff is theoretically the Sovereign's judicial representative in the county, while the Lord Lieutenant is the Sovereign's personal representative, their jurisdictions, the "shrieval counties", are no longer co-terminous with administrative areas, representing a mix between the ancient counties and more recent local authority areas.

The post is unpaid, except for a small court attendance allowance, the general expenses of the office are borne by the holder. Eligibility for nomination and appointment of High Sheriffs is controlled by the Sheriffs Act of 1887. C1061 Godwine 1066-1068 Tovid or Tofig 1083-1086 William de Moyon oooo

Hoodoo Peak

Hoodoo Peak is a 8,464-foot mountain summit located in the Methow Mountains, a sub-range of the North Cascades in Washington State. It is protected by the Lake Chelan-Sawtooth Wilderness within the Okanogan National Forest; the nearest higher peak is 0.93 miles to the south. Precipitation runoff on the west side of the mountain drains into Buttermilk Creek, whereas the east side of the mountain drains into Libby Creek. Lying east of the Cascade crest, the area around Hoodoo Peak is a bit drier than areas to the west. Summers can bring occasional thunderstorms. With its impressive height, Hoodoo Peak can have snow on it in late-spring and early-fall, can be cold in the winter; the North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks and deep glacial valleys. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences; these climate differences lead to vegetation variety defining the ecoregions in this area.

The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch. With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted. In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago. During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating scoured the landscape leaving deposits of rock debris; the "U"-shaped cross section of the river valleys are a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.

Pazeh people

The Pazeh people, including the Kaxabu, are the descendants of the Pazeh-speaking indigenous people from Taichung and Miaoli areas of Taiwan. Due to the processes of acculturation and cultural assimilation, the majority of Taiwanese who identify themselves as Pazeh reside in the Ai-lan district in the central city of Puli, Nantou. Christian missionaries arrived in Taiwan in 1865, the Pazeh people in the area were converted to the religion by 1871; the current Pazih community is located around the Ai-lan Taiwanese Presbyterian Church, which provides support for the Pazeh cultural revival and political mobilization. Presbyterian minister Rev. Daxawan Lai built a museum for Pazeh artifacts and to be a center for Pazeh language learning and cultural activities; the Ai-lan Pazih are petitioning Taiwan's government for official status as a recognized Taiwanese Aboriginal ethnic group.

Duke of Bronte (1800 ship)

Duke of Bronte ) was launched in 1793 in India, under another name. She was renamed in 1800 in London, she made two voyages as a slaver before a French privateer captured her in 1804. Duke of Bronti was admitted to the Registry of Great Britain on 17 November 1800, she first appears in Lloyd's Register in the supplemental pages to the 1800 volume. Her master is R. Beal, her owner Morton, her trade London−Africa, she first appears in the Register of Shipping in 1801, with R. Beale, T. Morton, owner. Captain Richard P. Beale sailed her to Sierra Leone in 1801, she took the slaves. In 1803 Beale sailed Duke of Bronte on her second, what would be her last, slaving voyage. Between the voyages, T. Moreton had sold her to Anthony Calvert, of Camden and King, it is not clear where Beale and Duke of Bronte gathered her slaves, but she delivered them to Jamaica. On 3 February 1804, Lloyd's List reported that Duke of Bronti, bound for London, had to put back to Jamaica. On 22 June, Lloyd's List reported that a French privateer had captured Duke of Bronti as she was sailing from Jamaica to London and took her into Santiago de Cuba.
