Sampson (crater)
Sampson is a relatively tiny lunar impact crater located near the central part of the Mare Imbrium. It was named after British astronomer Ralph Allan Sampson. To the northeast is the crater Landsteiner and to the southeast lies Timocharis. East of this crater is the Dorsum Grabau, a wrinkle ridge in the mare A mare is an adult female horse or other equine. In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than fo ....

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] |
Lunar Mare
The lunar maria (; singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient asteroid impacts on the far side on the Moon that triggered volcanic activity on the opposite (near) side. They were dubbed , Latin for 'seas', by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features (Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Procellarum ...

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 ...

Wrinkle Ridge
A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created after the lava cooled and solidified. They frequently outline ring structures buried within the mare, follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called ''veins'' due to their resemblance to the veins that protrude from beneath the skin. Wrinkle ridges are named with the Latin designation ''dorsum'' (plural ''dorsa''). The standard IAU nomenclature uses the names of people (generally scientists) to identify wrinkle ridges on the Moon. For example, the Dorsa Burnet are named for Thomas Burnet, and the Dorsum Owen is named after George Owen of Henllys. Wrinkle ridges can also be found on Mars, for example in Chryse Planitia, on several of the asteroids that have been visited by sp ...

Ralph Allan Sampson
Ralph Allan (or Allen) Sampson FRS FRSE LLD (25 June 1866 – 7 November 1939) was a British astronomer. Life Sampson was born in Schull, County Cork in Ireland, then part of the UK. He was the fourth of five children to James Sampson, a Cornish-born metallurgical chemist, and his wife, Sarah Anne Macdermott. The family moved to Liverpool and Sampson attended the Liverpool Institute and then graduated from St. John's College, Cambridge in 1888. In 1891 he was awarded a scholarship to carry out astronomical research at Cambridge University. (He had been a student of astronomer John Couch Adams, and helped to edit and publish Part I of the second volume of Adams' papers in 1900). In 1893, Sampson was made Professor of Mathematics at Durham College of Science in Newcastle-on-Tyne and was elected Professor of Mathematics at Durham University in 1895. In December 1910, he became Astronomer Royal for Scotland (until 1937) and Professor of Astronomy at the University of Edinburgh. ...

Timocharis (crater)
Timocharis is a prominent lunar impact crater located on the Mare Imbrium. It was named after ancient Greek astronomer Timocharis. The closest crater of comparable dimensions is Lambert to the west. The smaller craters Feuillée and Beer lie to the east of Timocharis. The rim of Timocharis has a somewhat polygonal outline, with an outer rampart that extends over 20 kilometers in all directions. The interior wall is slumped and sharply terraced. The center of the floor is occupied by a craterlet that lies on a slight rise. This impact has almost completely removed the original central peak. The crater may have a minor ray system that extends for over . The crater is likely to have been formed in the Eratosthenian, between 3.2 and 1.1 Billion years ago, as it lacks a prominent ray system, but has not been significantly eroded by impacts.
