Möbius (crater)
Möbius is a Lunar craters, lunar impact crater that is located on the Moon's Far side (Moon), far side, beyond the eastern limb and northeast of the Mare Marginis. It lies less than one crater diameter to the northwest of the larger, 90-km-diameter Hertz (crater), Hertz, and just to the southeast of Popov (crater), Popov. To the north of Mobius is the crater chain designated Catena Dziewulski, which takes its name from the crater Dziewulski (crater), Dziewulski to the north-northwest. This is a moderately worn crater formation, with a smaller crater intruding into the western rim and a small crater cutting across the rim at the southern end. The rim is relatively low and the interior is marked only by a few tiny craterlets and some higher-albedo markings in the southwestern quadrant. Prior to naming in 1970 by the International Astronomical Union, IAU, this crater was known as ''Crater 196''. References * * * * * * * * * * * * {{DEFAULTSORT:Mobius Impact crat ...

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dziewulski (crater)
Dziewulski is a lunar impact crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim and the interior floor. The northern rim is also heavily disrupted, and several small crater lie along the southeast rim. The interior floor and surrounding terrain Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word ... has been resurfaced. Beginning at the southern edge, a chain of craters forms a linear formation running to the southeast past Popov. This feature is named Catena Dziewulski.

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.

Albedo
Albedo (; ) is the measure of the diffuse reflection of sunlight, solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of Radiosity (radiometry), radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popov (crater)
Popov is a Impact crater, crater on the Far side (Moon), far side of the Moon, just beyond the eastern limb. It measures approximately in diameter and is located along the very edge of the area of surface that is sometimes brought into view of the Earth during periods of favorable libration and illumination. However even at such times it is not prominent and can only be viewed edge-on. Description This crater lies due south of Dziewulski (crater), Dziewulski, and the crater chain designated Catena Dziewulski passes just to the northeast of Popov's outer rim. Just to the southeast of Popov lies Möbius (crater), Möbius, and the two are joined together by a smaller crater that lies along the south-southeast rim of Popov. To the southwest lies the crater Ginzel (crater), Ginzel and Mare Marginis. Popov is a worn crater with a damaged outer rim that is little more than a circular, jumbled series of ridges in the surface. Several small craterlets lie along the rim and inner wall, ...

August Ferdinand Möbius
August Ferdinand Möbius (, ; ; 17 November 1790 – 26 September 1868) was a German mathematician and theoretical astronomer. Early life and education Möbius was born in Schulpforta, Electorate of Saxony, and was descended on his mother's side from religious reformer Martin Luther. He was home-schooled until he was 13, when he attended the college in Schulpforta in 1803, and studied there, graduating in 1809. He then enrolled at the University of Leipzig, where he studied astronomy under the mathematician and astronomer Karl Mollweide.August Ferdinand Möbius, The MacTutor History of Mathematics archive History.mcs.st-andrews.ac.uk.

Hertz (crater)
Hertz is a lunar impact crater that lies on the far side of the Moon, just behind the eastern limb. Due to libration this feature can sometimes be observed from the Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surfa ... under favorable lighting conditions. It is located to the west-southwest of the larger crater Fleming and north-northeast of the smaller Moiseev. Moiseev is joined to Hertz by the satellite crater Moiseev Z, and the three form a short crater chain. This is a somewhat worn crater formation with a wide inner wall. There is a pear-shaped crater along the northern inner wall. The interior floor is relatively featureless, with only a small ridge offset to the southwest of the midpoint. The crater was named after the German physicist Heinrich Rudolf Hertz in 1961 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
