Polzunov (crater)
Polzunov is a lunar impact crater that is located just to the south-southeast of the larger crater Seyfert, on the far side of the Moon. It was named after Russian heat engineer Ivan I. Polzunov. About one crater diameter to the west-southwest lies Deutsch Deutsch or Deutsche may refer to: *''Deutsch'' or ''(das) Deutsche'': the German language, in Germany and other places *''Deutsche'': Germans, as a weak masculine, feminine or plural demonym *Deutsch (word), originally referring to the Germanic ve ..., and somewhat farther to the south-southeast is Olcott. This crater has a worn and eroded outer rim, although it is marked only by a few small craterlets. Along the southwestern exterior is the satellite crater Polzunov N, a relatively fresh crater with a prominent central peak. The interior of Polzunov is marked only by an uneven region near the northern end of the crater. There is no central peak to speak of, and the remainder of the floor is relatively level and marked onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 16
Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's " J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to E ...

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Seyfert (crater)
Seyfert is a prominent lunar impact crater that is located on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It was named after American astronomer Carl Keenan Seyfert. It lies behind the eastern limb of the Moon, to the east of the crater Espin. Just to the north of Seyfert is the crater Harriot and equally close to the south is Polzunov. The outer rim of this crater is slightly elongated to the north, and the northeastern rim is overlain by the satellite crater Seyfert A. This overlapping impact crater has a central ridge on its interior floor. There is a low ridge near the midpoint of Seyfert, but it is less prominent. The inner wall of Seyfert is wider along the northern edge, west of Seyfert A. Several small craters lie along the rim and in ...

Far Side (Moon)
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Soviet Luna 3 space probe. The Soviet Academy of Sciences published the ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsch (crater)
Deutsch is a lunar impact crater on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It lies to the southwest of the larger crater Seyfert. About one crater to the east-northeast is Polzunov. Its name comes from Armin Joseph Deutsch, an American astronomer and science-fiction author. This crater has a relatively low, eroded rim that is heavily damaged along the southeastern section. This portion is overlain by Deutsch F along the east and Deutsch L to the south, with an irregular region between these two formations. The interior floor of Deutsch is relatively level, but is marked by a number of small impacts. A ray from Giordano Bruno to the north-northwest passes along the western edge of Deutsch. Satellite craters By convention these features ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olcott (crater)
Olcott is a relatively fresh crater on the far side of the Moon. It was named after American astronomer William Tyler Olcott. It lies to the south-southeast of the craters Seyfert and Polzunov, and to the north of Kostinskiy. This crater lacks any significant appearance of erosion from subsequent impacts, and its features are relatively well-defined. The rim edge is generally circular, with a slight outward bulge to the northeast and a larger bulge to the south. It has an outer rampart and some terraces and slumped edges along the inner wall. Several low ridges lie near the interior midpoint, with the western pair near the center and the eastern peaks offset towards the eastern rim. The satellite craters Olcott M and Olcott L form an overlapping pair along the southern outer rampart of Olcott, with the smaller member of the pair Olcott L overlapping Olcott M. The satellite crater Olcott E is partly overlain by the eastern rim of Olcott. Prior to naming in 1970 by the IAU ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...
