Bredikhin (crater)
Bredikhin is a lunar impact crater that is located on the far side of the Moon. It lies just to the west of the crater Mitra, and northeast of Raimond. This is a worn crater formation with features that have been dusted by material from the ray system of Jackson, about three crater diameters to the northwest. The rim is overlaid by a small crater along the west-northwest, and by a formation of craterlets along the southwest. The most prominent feature within the interior is the crater which overlays much of the northwest floor, including the midpoint. Bredikhin lies within the Dirichlet-Jackson Basin. 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 Bredikhin.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 campaign ...

Jackson (crater)
Jackson is a prominent lunar impact crater that is located in the northern hemisphere on the far side of the Moon. Less than one crater to the northeast is the crater Mineur, and to the south-southwest lies McMath. This crater created a large ray system. A skirt of higher-albedo material covers the surface within one crater diameter, with a slightly darker band along the outer ramparts. Beyond that radius, the rays form wide sections that grow increasingly diffuse and wispy with distance. The largest sections lie in roughly 90° arcs to the northeast and southwest, while a narrower arc projects to the south-southeast. The rays continue for hundreds of kilometers across the surface. The rim of the crater is well-defined and not significantly worn. The edge is somewhat polygonal in shape, with the southeastern rim being more rounded. The inner walls display some terracing. The interior floor is generally level with some irregularities in the northeastern part. Parts of the floor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fedor Aleksandrovich Bredikhin
Fyodor Aleksandrovich Bredikhin (russian: Фёдор Александрович Бредихин, 8 December 1831 – 14 May 1904 ( O.S.: 1 May)) was a Russian astronomer. His surname is sometimes given as Bredichin in the literature, and non-Russian sources sometimes render his first name as Theodor. Information In 1857 he joined the staff of the observatory at Moscow University, becoming its director in 1873. In 1890 he became director of Pulkovo Observatory (until 1894) and in the same year became a member of the Russian Academy of Sciences. He studied the theory of comet tails, and also studied meteors and meteor showers. The asteroid 786 Bredichina and the crater Bredikhin on the Moon are named after him.

Ray System
A ray system comprises radial streaks of fine ''ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter of their originating crater, and are often accompanied by small secondary craters formed by larger chunks of ejecta. Ray systems have been identified on the Moon, Earth (Kamil Crater), Mercury, and some moons of the outer planets. Originally it was thought that they existed only on planets or moons lacking an atmosphere, but more recently they have been identified on Mars in infrared images taken from orbit by '' 2001 Mars Odyssey''s thermal imager. Rays appear at visible, and in some cases infrared wavelengths, when ejecta are made of material with different reflectivity (i.e., albedo) or thermal properties from the surface on which they are deposited. Typically, visible rays have a higher albedo than the surrounding surface. More rar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raimond (crater)
Raimond is a lunar impact crater that lies on the Moon's far side. Less than one crater diameter to the northeast is Bredikhin, and farther to the west is McMath. To the north-northwest lies the prominent crater Jackson, which is surrounded by a large ray system. Raimond is almost completely covered by this ray material, and a pair of prominent rays cross the northeastern and southwestern portions of the crater. This crater is slightly elongated along the east–west axis, giving is a slightly oblong appearance. The rim edge is moderately worn, although no significant impacts lie across the edge. The interior is relatively featureless, with only a few small craterlets and the ray material from Jackson crater to mark the surface. Raimond lies near the center of the Dirichlet-Jackson Basin. 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 Raimond. See also * 1450 Raim ...
