Probe Ridge
Probe Ridge () is a prominent, snow-free, terraced ridge forming part of the north flank of Viking Valley, situated in the southeast portion of Alexander Island, Antarctica. The ridge was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1993 after the space probe which surveyed the planet Mars in 1976.

Viking Valley
Viking Valley () is a valley lying on the east side of Mars Glacier containing a braided stream which feeds into Secret Lake, situated in the southeast corner of Alexander Island, Antarctica. This area was the prime research site of the 1992-93 Mars Glacier field party led by D. D. Wynn-Williams. The feature was named by the United Kingdom Antarctic Place-Names Committee in 1993 in association with nearby Mars Glacier. The name "Viking" stems from the Viking Lander project of NASA which first searched for life on Mars in 1976.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Leda Ridge
Leda Ridge () is a ridge running in a northeast–southwest direction lying on the west side of the Ganymede Heights, east of Jupiter Glacier, on the east side of Alexander Island, Antarctica. The ridge was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and was mapped from the photographs by the Falkland Islands Dependencies Survey in 1960. It was named by the UK Antarctic Place-Names Committee after Leda, a satellite of the planet Jupiter, in association with nearby Jupiter Glacier.

Polarstar Ridge
Polarstar Ridge () is a jagged ridge, 4 nautical miles (7 km) long, trending southwest from The Obelisk in the Staccato Peaks, situated in the southern portion of Alexander Island, Antarctica. The ridge was named by the Advisory Committee on Antarctic Names (US-ACAN) after the Polar Star, the low-wing monoplane from which Lincoln Ellsworth, with pilot Herbert Hollick-Kenyon, discovered and photographed this ridge and the Staccato Peaks on November 23, 1935.
