Jarvis (crater)
Jarvis is a crater that lies on the far side of the Moon. It is located within the walled plain Apollo, and lies in the eastern half of this basin within the interior ring. Jarvis has a low, somewhat worn outer rim that is generally circular. There is a wide break in the south-southeastern portion of the rim where is it partly overlain by the crater McNair. The latter is younger than Jarvis, since its rim still survives where it intersects the interior of Jarvis. The interior of the crater is otherwise undistinguished, being marked only by tiny craters and some low ridges along the ramparts of McNair. The crater name was approved by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach ... in 1988 in honor of Gregory Jarvis, killed in the Space Shuttle ''Challenger'' disaster ...

Lunar Orbiter 5
Lunar Orbiter 5, the last of the " Lunar Orbiter series", was designed to take additional Apollo and Surveyor landing site photography and to take broad survey images of unphotographed parts of the Moon's far side. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data and was used to evaluate the Manned Space Flight Network tracking stations and Apollo Orbit Determination Program. Mission Summary The spacecraft was placed in a cislunar trajectory and on August 5, 1967 was injected into an elliptical near polar lunar orbit with an inclination of 85 degrees and a period of 8 hours 30 minutes. On August 7 the perilune was lowered to , and on August 9 the orbit was lowered to a , 3 hour 11 minute period. The spacecraft acquired photographic data from August 6 to 18, 1967, and readout occurred until August 27, 1967. A total of 633 high resolution and 211 medium resolution frames at resolution down to were acquired, bringing the cumulati ...

McNair (crater)
McNair is a small lunar impact crater on the far side of the Moon. It lies within the double-ringed Apollo basin, inside the eastern part of the interior ring. It has partly merged with the crater Jarvis, and the two share a common rim. To the south of McNair lies Borman. This is a bowl-shaped feature with a somewhat worn outer rim. There are some tiny craterlets along the southern rim, and a narrow cut through the edge to the south-southwest. The interior floor is relatively featureless. The crater name was approved by the IAU in 1988 in honor of Ronald McNair, killed in the Space Shuttle ''Challenger'' disaster on January 28, 1986.

Gregory Jarvis
Gregory Bruce Jarvis (August 24, 1944 – January 28, 1986) was an American engineer and astronaut who died during the destruction of the Space Shuttle ''Challenger'' on mission STS-51-L, where he was serving as payload specialist for Hughes Aircraft. Education Jarvis graduated from Mohawk Central High School (later renamed to Gregory B. Jarvis High School, which eventually became the Gregory B. Jarvis Middle School in his honor), in Mohawk, New York, in 1962. He received a Bachelor of Science degree in electrical engineering from the State University of New York at Buffalo in 1967, and a Master of Science degree in the same discipline from Northeastern University in 1969. Jarvis joined the United States Air Force the same year and served until 1973, when he was honorably discharged as a Captain. Thereafter he worked for Hughes Aircraft. Space Shuttle ''Challenger'' disaster In June 1984, Jarvis was one of two Hughes Aircraft employees selected as candidates for the Space Sh ...

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] |
Apollo (crater)
Apollo is an enormous impact crater located in the southern hemisphere on the far side of the Moon. This formation dwarfs the large crater Oppenheimer that is located next to the western rim. The crater Barringer lies across the northern wall. To the southeast is the crater Anders, and Kleymenov is just to the east of the rim. Apollo is a double-ringed walled plain (or basin) whose inner ring is roughly half the diameter of the outer wall. Both the outer wall and the interior have been heavily worn and eroded by subsequent impacts, so that significant parts of the outer and inner walls now consist of irregular and incised sections of mountainous arcs. The interior floor is covered in a multitude of craters of various sizes, some of which have been named for people associated with the Apollo program or other NASA projects. Sections of Apollo's interior have been resurfaced with lava, leaving patches of the floor with a lower albedo than the surroundings. There is a large pat ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Challenger Disaster
On January 28, 1986, the broke apart 73 seconds into its flight, killing all seven crew members aboard. The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. EST (16:39 UTC). It was the first fatal accident involving an American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the orbiter and the twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit, in addition to taking school teacher Christa McAuliffe into space. The latter resulted in a higher than usual media interest and coverage of the mission; the launch and subsequent disaster were seen live in many schools across the United States. The cause of the disaster was the failure of the two O-ring seals in a joint in the shuttle's right solid rocket booster (SRB). The record-low temperatures of the launch had stiffened the rubb ...

Borman (crater)
Borman is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies across the southeast section of the mountainous inner ring, within the walled basin named Apollo. The rim of Borman remains sharp-edged, although a smaller crater lies across its northwestern rim. The interior is rough but relatively flat. Borman L is an older and much more worn crater that is attached to the southern rim of Borman. Borman crater is named after the American astronaut Frank Borman. In 1968, Borman and his Apollo 8 crewmates became the first humans to orbit the Moon. Two nearby craters are named after the other crew members, William Anders ( Anders crater) and Jim Lovell ( Lovell crater). 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 Borman. The following craters have been renamed by the IAU. * Borman A — ''See'' McNair (crater). * Borma ... [...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 m ...
