Vostok Rupes is an escarpment on Mercury. The scarp is a surface manifestation of a thrust fault, which formed when the planet contracted as its interior cooled. [2]
Vostok Rupes cuts across the crater Guido d'Arezzo and across a larger, unnamed crater to the northwest.
Vostok Rupes is named after Russian ship Vostok, which led the First Russian Antarctic Expedition in 1819–1821, commanded by Fabian Gottlieb von Bellingshausen. [1]
Vostok refers to east in Russian but may also refer to:
Discovery Rupes is an escarpment on Mercury approximately 650 kilometers (400 mi) long and 2 kilometres (6,562 ft) high, located at latitude 56.3 S and longitude 38.3 W. It was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time. The scarp cuts through Rameau crater. It was discovered by Mariner 10.
Antoniadi Dorsum is a ridge on Mercury at 25.1°N 30.5°W, and it is approximately 359 km in length. In 1976, it was named by the International Astronomical Union after Eugène Michel Antoniadi.
Sobkou Planitia is a large basin on the planet Mercury. It is named after the ancient Egyptian messenger deity Sobkou. He was associated by the Egyptians with the planet Mercury.
Rameau is a crater on Mercury. It was named by the IAU in 1976, after French composer Jean Philippe Rameau.
Beethoven is a crater at latitude 20°S, longitude 124°W on Mercury. It is 630 km in diameter and was named after Ludwig van Beethoven. It is the eleventh largest named impact crater in the Solar System and the third largest on Mercury.
The Discovery quadrangle lies within the heavily cratered part of Mercury in a region roughly antipodal to the 1550-km-wide Caloris Basin. Like the rest of the heavily cratered part of the planet, the quadrangle contains a spectrum of craters and basins ranging in size from those at the limit of resolution of the best photographs to those as much as 350 km across, and ranging in degree of freshness from pristine to severely degraded. Interspersed with the craters and basins both in space and time are plains deposits that are probably of several different origins. Because of its small size and very early segregation into core and crust, Mercury has seemingly been a dead planet for a long time—possibly longer than the Moon. Its geologic history, therefore, records with considerable clarity some of the earliest and most violent events that took place in the inner Solar System.
Victoria Rupes is an escarpment in the Victoria quadrangle of Mercury. The quadrangle was named after this escarpment, and the escarpment itself was named after the Victoria, a ship used on the famous expedition of Ferdinand Magellan. Its name was adopted by the International Astronomical Union (IAU) in 1976.
Beagle Rupes is an escarpment on Mercury, one of the highest and longest yet seen. It was discovered in 2008 when MESSENGER made its first flyby of the planet. It has an arcuate shape and is about 600 km long. The scarp is a surface manifestation of a thrust fault, which formed when the planet contracted as its interior cooled.
Sveinsdóttir is a large impact crater on Mercury. Its dimensions are 220 × 120 km.
Izquierdo is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2009, for the Mexican painter María Izquierdo. The floor of Izquierdo is smooth, the result of having been partially filled with volcanic lava. Circular outlines of the rims of “ghost craters” – smaller, older craters that have been largely buried by the lavas that infilled the basin – are visible in a few places on Izquierdo's floor. The remnants of a buried inner ring are also barely discernible in spots, and it is one of 110 peak ring basins on Mercury. There have been more recent impacts into the floor of Izquierdo, resulting in some small, sharply defined craters.
Glinka is a pit-floored crater on Mercury, which was discovered in 1974 by Mariner 10 spacecraft. It was named by the IAU in 2008, after Russian composer Mikhail Glinka.
Hero Rupes is an escarpment on Mercury more than 300 kilometres long located in the southern hemisphere of Mercury. Discovered by the Mariner 10 spacecraft in 1974, it was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time.
Vostok was a 28-gun sloop-of-war of the Imperial Russian Navy, the lead ship of the First Russian Antarctic Expedition in 1819–1821, during which Fabian Gottlieb von Bellingshausen and Mikhail Lazarev circumnavigated the globe, discovered the continent of Antarctica and twice circumnavigated it, and discovered a number of islands and archipelagos in the Southern Ocean and the Pacific.
Mirny was a 20-gun sloop-of-war of the Imperial Russian Navy, the second ship of the First Russian Antarctic Expedition in 1819–1821, during which Fabian Gottlieb von Bellingshausen and Mikhail Lazarev circumnavigated the globe, discovered the continent of Antarctica and twice circumnavigated it, and discovered a number of islands and archipelagos in the Southern Ocean and the Pacific.
Guido d'Arezzo is a crater on Mercury. It has a diameter of 58 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Guido d'Arezzo is named for the Italian music theorist Guido of Arezzo, who lived from 990 to 1050.
Leopardi is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1976. Leopardi is named for the Italian writer Giacomo Leopardi, who lived from 1798 to 1837.
Ghost craters on the planet Mercury have tectonic features such as graben and wrinkle ridges. These features were formed by extensional and contractional forces originating in tectonic processes such as uplift and global contraction. The combination of graben and wrinkle ridges inside ghost craters found on Mercury has not been observed on any of the other terrestrial planets.
Enheduanna is a crater on Mercury. It has a diameter of 105 kilometers. Its name was suggested by Gagan Toor from India in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Enheduanna is named for the Sumerian poet Enheduanna. The craters Carolan, Kulthum, Karsh, and Rivera were also named as part of the contest.
