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 ...

Polygon
In geometry, a polygon () is a plane figure made up of line segments connected to form a closed polygonal chain. The segments of a closed polygonal chain are called its '' edges'' or ''sides''. The points where two edges meet are the polygon's '' vertices'' or ''corners''. 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. More precisely, the only allowed intersections among the line segments that make up the polygon are the shared endpoints of consecutive segments in the polygonal chain. A simple polygon is the boundary of a region of the plane that is called a ''solid polygon''. The interior of a solid polygon is its ''body'', also known as a ''polygonal region'' or ''polygonal area''. In contexts where one is concerned only with simple and solid polygons, a ''polygon'' may refer only to a simple polygon or to a solid polygon. A polygonal chain may cross over itself, creating star polyg ... [...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 it was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities, spacecraft developments, and newly released space-related data. McDowell's report occasionally corrects NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States ...'s official web sites, or provides additional data on classified launches that are not available elsewhere ...

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. Macrobius is a crater of Lower (Early) Imbrian age. |
Simon Newcomb
Simon Newcomb (March 12, 1835 – July 11, 1909) was a Canadians, Canadian–Americans, 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 B.S. 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, Wallace, Nova Scotia. His parents were John Burton Newcomb and his wife Emily Prince.

Römer (crater)
Römer is a Lunar craters, lunar impact crater that is located to the north of the Sinus Amoris 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 large central peak at the midpoint. Römer has a ray system, and due to these rays, it is mapped as part of the Copernican period, Copernican System.The geologic history of the Moon, 1987, Donald Wilhelms, Wilhelms, Don E.; with sections by ...
