Onizuka (crater)
Onizuka is a small lunar impact crater that lies within the inner ring of the walled plain Apollo. The central portion of Apollo has been covered by dark basaltic lava, and Onizuka lies at the southern edge of this plain. To the southeast of Onizuka is the crater Borman Borman is a surname. Notable people with the surname include: * Danleigh Borman (born 1985), South African soccer player *Frank Borman (1928–2023), American astronaut **The Frank Borman Expressway in Indiana named after him * Geoffrey D. Borman, ..., and to the west-southwest is Chaffee. Onizuka is a circular, bowl-shaped crater with a sharp edge. The inner walls are simple slopes down to the interior floor, although piles of talus lie at the base of some sections of the wall. There is a small central peak at the midpoint of the interior floor. A fine groove in the surface begins at the northern rim of Onizuka and leads away across the floor of Apollo to the east.

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.

Ellison Onizuka
was an American astronaut, engineer, and USAF test pilot from Kealakekua, Hawaii, who successfully flew into space with the Space Shuttle ''Discovery'' on STS-51-C. He died in the destruction of the Space Shuttle ''Challenger'', on which he was serving as Mission Specialist for mission STS-51-L. He was the first Asian American and the first person of Japanese origin to reach space. Early life Born on June 24, 1946, Onizuka was the oldest son and second-youngest child of Masamitsu and Mitsue Onizuka. He was a Buddhist. He had two older sisters, Shirley and Norma, and a younger brother, Claude, who became the family spokesman after the ''Challenger'' disaster. Growing up, Ellison was an active participant in FFA, 4-H, and the Boy Scouts of America, where he reached the level of Eagle Scout. Onizuka graduated from Konawaena High School in 1964. He received a Bachelor of Science degree in Aerospace Engineering in June 1969, and a Master of Science degree in that field in Dece ...

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 ...

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 patch ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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). * Borman X ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chaffee (crater)
Chaffee is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies within the huge walled plain Apollo, and is one of several craters in that formation named for astronauts and people associated with the Apollo program. This basin is a double-ringed formation, and the crater Chaffee is situated across the southwest part of the inner ring. The ridge from this ring extends northward from the northern rim of Chaffee. This is a circular crater with an outer rim that has an uneven form due to multiple small outward bulges. The perimeter is only slightly worn, and retains a sharp rim that projects above the surroundings. Two notable craters are attached to the outer rim: Chaffee F to the west and Chaffee W along the northwest. Chaffee actually intrudes somewhat into the former crater, and the two share a common rim. There is also a tiny craterlet exactly on the rim to the south-southeast. The inner walls of Chaffee do not have a well-form ...

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

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 ...
