Fermi (crater)
Fermi is a large Lunar craters, lunar impact crater of the category named a walled plain. It was named after Italian-American physicist and Nobel laureate Enrico Fermi. It lies on the Far side (Moon), far side of the Moon and can not be viewed from the Earth. Thus this feature must be viewed from an orbiting spacecraft. The most notable aspect of Fermi is that the large and prominent crater Tsiolkovskiy (crater), Tsiolkovskiy intrudes into its southeastern rim. Unlike Tsiolkovskiy, however, the interior of Fermi is not covered by dark basaltic lava, and so it is barely distinguishable from the surrounding rugged and battered terrain. If it were located on the near side of the Moon, however, this would be one of the largest visible craters, with a dimension roughly equal to the crater Humboldt (crater), Humboldt, lying several hundred kilometers to the west-southwest. This formation has been significantly eroded and damaged by subsequent impacts, and several notable craters lie a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Orbiter 3
The Lunar Orbiter 3 was a spacecraft launched by NASA in 1967 as part of the Lunar Orbiter program, Lunar Orbiter Program. It was designed primarily to photograph areas of the Moon, lunar surface for confirmation of safe landing sites for the Surveyor program, Surveyor and Apollo program, Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a cislunar trajectory and injected into an elliptical near-equatorial lunar orbit on February 8 at 21:54 UT. The orbit was with an inclination of 20.9 degrees and a period of 3 hours 25 minutes. After four days (25 orbits) of tracking the orbit was changed to . The spacecraft acquired photographic data from February 15 to 23, 1967, and readout occurred through March 2, 1967. The film advance mechanism showed erratic behavior during this period resulting in a decision to begin readout of the frames earlier than planned. The frames were r ...

Humboldt (crater)
Humboldt is a large lunar impact crater that is located near the eastern limb of the Moon. Due to foreshortening this formation has an extremely oblong appearance. The actual shape of the crater is an irregular circle, with a significant indentation along the southeastern rim where the prominent crater Barnard intrudes. To the north-northwest of Humboldt is the large crater Hecataeus. Phillips is attached to the western rim. The rim of Humboldt is low, worn, and irregular in outline. The central peak forms a range on the crater floor. The floor surface contains a network of rilles forming a pattern of radial spokes and concentric arcs. There are also some dark patches located near the walls to the northeast, northwest, and southeast. There is a chain of craters leading from the northwest crater rim to a distance almost as long as the crater is wide. This formation is designated Catena Humboldt. Due to its location near the lunar limb, little detail was known about this crater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalmbach Books
Kalmbach Media (formerly Kalmbach Publishing Co.) is an American publisher of books and magazines, many of them railroad-related, located in Waukesha, Wisconsin. History The company's first publication was ''The Model Railroader'', which began publication in the summer of 1933 with a cover date of January 1934. A press release announcing the magazine appeared in August 1933, but did not receive much interest. In 1940, business was good enough for Kalmbach to launch another magazine about railroads in general with the simple title of ''Trains Magazine''. From its first issue dated November 1940, it grew quickly from an initial circulation of just over 5,000. Kalmbach became exclusively a publisher when it discontinued its printing operations in 1973, opting to contract production from other printers. In 1985, Kalmbach purchased AstroMedia Corporation, adding its four magazines: ''Astronomy'', ''Deep Sky'', the children's science magazine ''Odyssey'' and ''Telescope Making'' ...

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 campaigne ...

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 ...

Litke (crater)
Litke is a lunar impact crater that lies within the large walled plain Fermi, near the north-northwestern inner rim. Less than one crater diameter to the west-northwest is the slightly larger Delporte. Litke is located on the far side of the Moon and cannot be viewed directly from the Earth. The rim of Litke is circular to the east and south, but the northern and western rims have been pushed inward somewhat. The west rim is irregular and broken through by a pair of worn depressions. Along the northern side slumped deposits form a pile along the base of the inner wall. A small craterlet lies along the southern rim and a small crater is attached to the exterior along the eastern side. The interior floor of litke has a low scarp that is nearly concentric with the eastern and southern sides. There is a small crater located on the interior floor just to the east of the midpoint.
