Katchalsky (crater)
Katchalsky is a crater that lies on the far side of the Moon. It was named after scientist Aharon Katzir-Katchalsky Aharon Katzir (Aharon Katzir-Katchalsky) (September 15, 1914 – May 30, 1972) was an Israeli pioneer in the study of the electrochemistry of biopolymers. Biography Born 1914 in Łódź, Poland, he moved to Mandatory Palestine in 1925, where he .... It lies to the southeast of the larger crater Lobachevskiy, and to the west of the prominent King. Less than a half-crater diameter to the southeast of Katchalsky is Viviani. The outer rim of Katchalsky is not quite circular, with outward bulges to the east and north, giving it a flat side along the northeastern edge. The rim is not markedly eroded, and the interior contains only a few tiny craterlets.

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 retu ...

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 ...

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 publi ...

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lobachevskiy (crater)
Lobachevskiy is a lunar impact crater that is located on the far side of the Moon, beyond the eastern limb. It was named after Russian mathematician Nikolai Lobachevsky in 1961. This crater lies to the southeast of the larger crater Fleming. Less than a crater diameter to the east-northeast lies Guyot. This is a well-formed crater with features that have not been significantly eroded since Lobachevskiy was first formed. The rim and inner wall are nearly free of significant overlapping impacts, although the satellite crater Lobachevskiy M is attached to the southern outer rim. The inner walls display terrace features, along with some slumping along the upper edge. Near the midpoint of the interior floor is a pair of central peaks, with one to the southeast and the other to the northwest of the middle. To the east of these peaks is a relatively bright, high- albedo patch that is most likely the result of a recent small impact. Two dark ribbons of material apparently emanate ...

King (crater)
King is a prominent lunar impact crater that is located on the far side of the Moon, and can not be viewed directly from Earth. The crater was named after Arthur Scott King and Edward Skinner King in 1970. Prior to that, this crater was known as ''Crater 211''. It forms a pair with Ibn Firnas, which is only slightly larger and is attached to the northeast rim of King. To the northwest is the crater Lobachevskiy, and Guyot is located an equal distance to the north-northwest. Description The outer rim of King is roughly circular but with a slightly irregular appearance, particularly at the northern end. The crater displays little appearance of wear. The inner walls are terraced, particularly along the eastern side. Within the walls is a somewhat uneven interior floor. The interior is irregular and ridged, particularly in the eastern half. The elongated, Y-shaped central rise is part of a ridge that runs to the southern rim. Due to its prominent rays, King is mapped as part of t ...

Viviani (crater)
Viviani is a small lunar impact crater that lies on the far side of the Moon. It was named after Italian mathematician and physicist Vincenzo Viviani. It is located due west of the prominent crater King, and just to the southeast of Katchalsky. This is a roughly circular, bowl-shaped crater with a well-defined rim edge and an inner wall that is wider along the southeastern half. A small crater has cut into the southern rim edge, and another small crater is attached to the exterior along the east. The inner walls are simple slopes that run down to the relatively level and featureless floor. 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 Viviani. In popular culture Viviani, along with another crater, Bingham, is referenced in the Midsomer Murders ''Midsomer Murders'' is a British crime drama television series, adapted by Anthony Horowitz and Douglas Watkinson from t ...

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 m ...

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaig ...
