Lane (crater)
Lane is a lunar impact crater. It lies on the far side of the Moon, just to the west of the crater Ten Bruggencate. To the west of Lane is Perepelkin, and to the northwest lies Love. This crater is not heavily eroded, but the rim is somewhat disrupted at the northern and southern ends. To the south the rim has a prominent outward bulge that extends an extra 5–10 km. The interior is somewhat uneven, with low central ridges near the midpoint. The crater was named after American astrophysicist Jonathan Homer Lane 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 1970.

Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans (astronaut), Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a Fe, Fi, Fo, Fum, and Phooey, biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample Lunar highlands, lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent Volcano, volcanic activity. They therefore selected Taurus– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonathan Homer Lane
Jonathan Homer Lane (August 9, 1819 – May 3, 1880) was an American astrophysicist and inventor. Biography Lane's parents were Mark and Henrietta (née Tenny) Lane and his education was at the Phillips Exeter Academy in Exeter, New Hampshire. He graduated from Yale University in 1846. While at Yale, Lane studied under astronomer Denison Olmsted. Olmsted’s interest in meteorology, particularly his support for James P. Espy’s thermodynamic model of storms, appear to closely parallel Lane’s later scientific interests and may have influenced him in that direction. Lane worked for the U.S. Patent Office, and became a principal examiner in 1851, continuing in that position until forced out by a change of political administrations in 1857. From 1860 to 1866, he lived with his brother, a blacksmith, in Franklin, Pennsylvania. During that time, he actively worked on developing an improved "cold apparatus" with which he hoped to reach temperatures as low as -345 °F (-209 ...

Lane Crater AS13-60-8620
In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median. Some roads and bridges that carry very low volumes of traffic are less than wide, and are only a single lane wide. Vehicles travelling in opposite directions must slow or stop to pass each other. In rural areas, these are often called country lanes. In urban areas, alleys are often only one lane wide. Urban and suburban one lane roads are often designated for one-way traffic. History For much of human history, roads did not need lane markings because most people walked or rode horses at relatively slow speeds. However, when auto ...

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 ...

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] |
Ten Bruggencate (crater)
Ten Bruggencate is a lunar impact crater that lies on the far side of the Moon from the Earth, just to the east of the younger crater Lane. To the southeast of Ten Bruggencate is Chauvenet. This is a worn and eroded formation, with the satellite crater Ten Bruggencate H overlapping part of the side to the east-southeast. There are several small craters along the inner wall and the edges of the interior floor. The crater is otherwise relatively featureless and unremarkable. The crater was named after German astronomer Paul ten Bruggencate 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 1970.

Perepelkin (lunar Crater)
Perepelkin is a lunar impact crater that is located just to the south of the similar crater Love. Attached to the exterior of its southern rim is the smaller Shirakatsi. Less than one crater diameter to the east-northeast is Lane, and to the west-southwest are the co-joined Danjon and D'Arsonval. The rim of this crater is relatively heavily eroded, and is similar in appearance to Love to the north. Along the western inner wall is an odd, pear-shaped crater that is probably a merge of two impacts. There is a short chain of small craters along the southwestern inner wall. The floor is pitted by tiny impacts, but is relatively level compared to the surrounding terrain. There is a small central peak at the midpoint that has a ridge extension to the southeast. The crater was named after Soviet astrophysicist Yevgeny Perepyolkin by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation wit ...

Love (crater)
Love is an impact crater on the far side of the Moon. It was named after British mathematician and geophysicist Augustus Edward Hough Love. It is located just to the north of the crater Perepelkin. Prager Prager (variants: Praeger, Preger) is a surname, which may refer to: Prager * David Prager (born 1977), American TV producer and blogger * Dennis Prager (born 1948), U.S. conservative radio talk show host, columnist and public speaker ** PragerU, ... nearly touches the northeastern rim. To the northwest is Bečvář. This is an eroded crater formation with several smaller craters along the rim. A chain of three small craters lies across the western rim and inner wall, and a crater cuts across the eastern rim. The inner walls have been worn and their features softened by impacts and possibly ejecta from other craters. The northern portion of the interior floor contains a considerable number of small and tiny craterlets that nearly form a continuous carpet in places. The southe ...

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 ...
