Meggers (crater)
Meggers is an impact crater that lies 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 physicist William F. Meggers. The rim of Meggers is roughly circular in form, with slight outward bulges to the southeast and northeast. The crater merges with a comparably sized formation to the northwest, and the intervening rim is somewhat irregular in form. The interior floor of Meggers is slightly irregular. Nearby craters of note include Olcott to the southwest, Innes, and Seyfert farther away to the northwest. To the east lies Vernadskiy. To the west is the crater Meggers S, a formation almost as large as Meggers itself. It has a rough interior and a tiny crater lies across the southern rim. Satellite craters By conventio ...

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 ...

William Frederick Meggers
William Frederick Meggers (July 13, 1888 – November 19, 1966) was an American physicist specialising in spectroscopy. Born in Clintonville, Wisconsin, he had to combine his early schooling with working on the family farm, but earned a scholarship to Ripon College, receiving a bachelor's degree in physics in 1910 and working as a research assistant. After a few years at the Carnegie Institute of Technology (now Carnegie Mellon University) in Pittsburgh, Pennsylvania, in 1914 he joined the National Bureau of Standards, and while working there earned his PhD from Johns Hopkins University. His work in spectrochemistry is generally credited to have sparked interest in the field in the United States, leading to him being dubbed ''the Dean of American spectroscopists''. In 1947 he received the Frederic Ives Medal. He was awarded the Elliott Cresson Medal in 1953. Since 1970, the Optical Society of America has awarded the William F. Meggers Award for outstanding work in spectroscopy ... [...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 ...

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] |
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] |
Innes (crater)
Innes is a Lunar craters, lunar impact crater on the Moon's Far side (Moon), far side. It is located less than a crater diameter to the east-southeast of the prominent crater Seyfert (crater), Seyfert. To the southeast of Innes is the crater Meggers (crater), Meggers, and to the west-southwest lies Polzunov (crater), Polzunov. This crater has not been significantly worn due to impact erosion, and the features remain well-defined. The shape is roughly circular with a slight outward bulge along the western edge. The inner walls have slumped somewhat, and some slight wiktionary:terrace, terracing has occurred. The interior floor is relatively featureless, and is marked only by a few tiny craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Innes.

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 ...

Vernadskiy (crater)
Vernadskiy is a lunar impact crater on the far side of the Moon, behind the visible eastern limb. It lies to the west-northwest of the smaller crater Siedentopf. To the south is Gavrilov, and much farther to the west is Meggers. This is a formation that has seen better days. The outer rim has been bombarded by a myriad of lesser impacts, producing an eroded and irregular edge. Attached to the outer rim to the northeast is the crater Florensky, an equally worn crater. The interior floor of Vernadskiy is also marked by a number of small impacts, although in general it is more level than the uneven terrain that surrounds the crater. In some sources the name is spelled as Vernadskyy, Vernadskij, or Vernadsky. The spelling followed in this article is that adopted by the IAU in 1970.

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 ...
