Newcomb (lunar Crater)
Newcomb is a lunar impact crater that is located in the rugged Montes Taurus mountain range, to the east of the Mare Serenitatis. It lies to the northeast of the prominent crater Römer, and north-northwest of Macrobius. This crater has a sharp-edged and somewhat irregular rim that appears polygonal more than circular. There are terraces along the inner sides, with some slumping along the northern and western inner edge. The south-southwestern part of the rim is overlaid by the smaller crater Newcomb A. The interior floor is uneven, particularly near the rim of Newcomb A. Just to the south-southeast of the crater is the satellite crater Newcomb J. This feature is named after the American astronomer Simon Newcomb. 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 Newcomb.

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...

Polygon
In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed ''polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two together, may be called a polygon. The segments of a polygonal circuit are called its '' edges'' or ''sides''. The points where two edges meet are the polygon's '' vertices'' (singular: vertex) or ''corners''. The interior of a solid polygon is sometimes called its ''body''. An ''n''-gon is a polygon with ''n'' sides; for example, a triangle is a 3-gon. A simple polygon is one which does not intersect itself. Mathematicians are often concerned only with the bounding polygonal chains of simple polygons and they often define a polygon accordingly. A polygonal boundary may be allowed to cross over itself, creating star polygons and other self-intersecting polygons. A polygon is a 2-dimensional example of the more general polytope in any number ... [...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 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 ...

855 Newcombia
855 Newcombia ('' prov. designation:'' ''or'' ) is a stony background asteroid from the inner regions of the asteroid belt. It was discovered on 3 April 1916, by astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula. The S-type asteroid has a notably short rotation period of 3.0 hours and measures approximately in diameter. It was named after Canadian–American astronomer Simon Newcomb (1835–1909). Orbit and classification ''Newcombia'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the inner main-belt at a distance of 1.9–2.8 AU once every 3 years and 8 months (1,326 days; semi-major axis of 2.36 AU).

Macrobius (crater)
Macrobius is a prominent lunar impact crater located to the northwest of the Mare Crisium. Its diameter is 63 km. It was named after ancient Roman writer Macrobius. It lies on the southeast edge of the Lacus Bonitatis, a small lunar mare. The somewhat smaller crater Tisserand lies just to the east. The outer wall of Macrobius has a multiply terraced inner surface, with some slumping along the top of the rim. The small satellite crater Macrobius C lies across the western rim, but the wall is otherwise relatively free of significant wear. In the center of the floor is a central mountain complex. There is a low ridge in the western interior, but the remainder of the floor is relatively level. 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 Macrobius. The following craters have been renamed by the IAU. * Macrobius A — ''See'' Carmichael. * Macrobius B — ''See' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simon Newcomb
Simon Newcomb (March 12, 1835 – July 11, 1909) was a Canadian–American astronomer, applied mathematician, and autodidactic polymath. He served as Professor of Mathematics in the United States Navy and at Johns Hopkins University. Born in Nova Scotia, at the age of 19 Newcomb left an apprenticeship to join his father in Massachusetts, where the latter was teaching. Though Newcomb had little conventional schooling, he completed a BSc at Harvard in 1858. He later made important contributions to timekeeping, as well as to other fields in applied mathematics, such as economics and statistics. Fluent in several languages, he also wrote and published several popular science books and a science fiction novel. Biography Early life Simon Newcomb was born in the town of Wallace, Nova Scotia. His parents were John Burton Newcomb and his wife Miriam Steeves. His father was an itinerant school teacher, and frequently moved in order to teach in different parts of Canada, particularly in N ...

Römer (crater)
Römer is a lunar impact crater that is located to the north of the Sinus Amoris Sinus Amoris (Latin ''sinus amōris'' "Bay of Love") extends northward from the northeast end of the Mare Tranquillitatis. It is located at selenographic coordinates 19.9° N, 37.3° E, and lies within a diameter of 190 km. To the north of ... in the northeast section of the Moon. It was named after Danish astronomer Ole Rømer. It lies in the southwestern part of the mountainous region named the Montes Taurus. It was unofficially named as Atatürk by astronomer Hugh Percy Wilkins in his lunar map, possibly due to the fact that the Montes Taurus (or Toros Dağları in Turkish language, Turkish) are located in Turkey. To the west-northwest is the crater-bay Le Monnier (crater), Le Monnier, on the eastern edge of Mare Serenitatis. The rim of Römer has relatively high walls with a wiktionary:terrace, terraced inner surface. There is a small craterlet on the north part of the floor, and a larg ...
