Lunar Rover
A lunar rover or Moon rover is a space exploration Rover (space exploration), vehicle designed to move across the surface of the Moon. The Apollo program's Lunar Roving Vehicle was driven on the Moon by members of three American crews, Apollo 15, Apollo 16, 16, and Apollo 17, 17. Other rovers have been partially or fully autonomous robots, such as the Soviet Union's Lunokhods, Chinese ''Yutu (rover), Yutus'', Indian ''Pragyan (Chandrayaan-3), Pragyan'', and Japan's Smart Lander for Investigating Moon#Rovers, LEVs. Five countries have had operating rovers on the Moon: the Soviet Union, the United States, China, India, and Japan. Variations in design Lunar rover designs have varied in several ways. Size and speed Lunokhod rovers were in length. The LRVs were long with a wheelbase, and achieved a top speed of during Apollo 17. Power The Lunokhod rovers, and others, used photovoltaic solar power. The LRV rovers were battery powered. Lunokhod and the Chinese ''Yutu'' rovers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar South Pole
The lunar south pole is the southernmost point on the Moon. It is of interest to scientists because of the lunar water, occurrence of water ice in Crater of eternal darkness, permanently shadowed areas around it. The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior. Such craters are cold trap (astronomy), cold traps that contain fossil records of hydrogen, water ice, and other volatiles dating from the Formation and evolution of the Solar System, early Solar System. In contrast, the lunar north pole region exhibits a much lower quantity of similarly sheltered craters. Geography The lunar south pole is located on the center of the polar Antarctic Circle (80°S to 90°S).Lunar South Pole. NASA. 2017. Accessed on 16 July 20 ...

Luna 21
''Luna 21'' (Ye-8 series) was an uncrewed space mission, and its spacecraft, of the Luna program, also called ''Lunik 21'', in 1973. The spacecraft landed on the Moon and deployed the second Soviet lunar rover, '' Lunokhod 2''. The primary objectives of the mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study mechanical properties of the lunar surface material. Mission ''Luna 21'' carried the second successful Soviet lunar rover, ''Lunokhod 2'', and was launched less than a month after the last Apollo lunar landing. The Proton-K/ D launcher put the spacecraft into Earth parking orbit followed by translunar injection. On 12 January 1973, ''Luna 21'' was braked into a 90 × 100 km orbit about the Moon, at a 60° inclination. On 13 and 14 January, the perilune ...

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a List of human spaceflight programs, human spaceflight program to serve as a commander or crew member of a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and space tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek ). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Standard Chinese, Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Object
An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. In astronomy, the terms ''object'' and ''body'' are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial ''object'' is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures. Examples of astronomical objects include planetary systems, star clusters, nebulae, and galaxies, while asteroids, moons, planets, and stars are astronomical bodies. A comet may be identified as both a body and an object: It is a ''body'' when referring to the frozen nucleus of ice and dust, and an ''object'' when describing the entire comet with its diffuse coma and tail. History Astronomical objects such as stars, planets, nebulae, aster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luna 17
''Luna 17'' (Ye-8 series) was an uncrewed space mission of the Luna program, also called ''Lunik 17''. It deployed the first robotic rover onto the surface of the Moon. Launch ''Luna 17'' was launched from an Earth parking orbit towards the Moon and entered lunar orbit on 15 November 1970. The spacecraft softly landed on the Moon in the Mare Imbrium (Sea of Rains). The spacecraft had dual ramps by which the payload, ''Lunokhod 1'', descended to the lunar surface. ''Lunokhod 1'' was a lunar vehicle formed of a tub-like compartment with a large convex lid on eight independently powered wheels. ''Lunokhod 1'' was equipped with a cone-shaped antenna, a highly directional helical antenna, four teleray spectrometer, an x-ray telescope, cosmic-ray detectors, and a laser retro-reflector (supplied by France) was also included. The vehicle was powered by a solar cell array mounted on the underside of the lid. ''Lunokhod 1'' was intended to operate through three lunar days but act ...

Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains") is a vast lunar mare, lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a Protoplanet, proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant Impact crater, crater to form the flat volcanic plain seen today. The basin's age has been estimated using Uranium–lead dating, uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of Lunar mare, mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it would have originally been when it first formed as a result of later events that have altered its surface. Origin Mare Imbrium formed when a proto-planet ...

Moon Landing
A Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon, including both crewed and robotic missions. The first human-made object to touch the Moon was Luna 2 in 1959. In 1969 Apollo 11 was the first crewed mission to land on the Moon. There were List of Apollo missions#Crewed missions, six crewed landings between 1969 and 1972, and numerous uncrewed landings. All crewed missions to the Moon were conducted by the Apollo program, with the last departing the lunar surface in December 1972. After Luna 24 in 1976 there were no Soft landing (aeronautics), soft landings on the Moon until Chang'e 3 in 2013. All soft landings took place on the near side of the Moon until January 2019, when Chang'e 4 made the first landing on the far side of the Moon. Uncrewed landings Government landings Six government space agencies, Interkosmos, NASA, China National Space Administration, CNSA, Department of Space, DOS, JAXA and European Space Agency, ESA, ha ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Lunokhod Program
Lunokhod ( rus, Луноход, p=lʊnɐˈxot, "Moonwalker") was a series of Soviet robotic lunar rovers designed to land on the Moon between 1969 and 1977. Lunokhod 1 was the first roving remote-controlled robot to land on an extraterrestrial body. The 1969 Lunokhod 1A (Lunokhod 0, Lunokhod No. 201) was destroyed during launch, the 1970 ''Lunokhod 1'' and the 1973 ''Lunokhod 2'' landed on the Moon, and ''Lunokhod 3'' (Lunokhod No. 205, planned for 1977) was never launched. The successful missions were in operation concurrently with the Zond and Luna series of Moon flyby, orbiter and landing missions. The Lunokhods were primarily designed to support the Soviet human Moon missions during the Moon race. Instead, they were used as remote-controlled robots for exploration of the lunar surface and returning pictures, after the Apollo human lunar landings and cancellation of the Soviet human Moon programme. The Lunokhods were transported to the lunar surface by Luna sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
