Bode (crater)
Bode is a small crater located near the central region of the Moon, to the northwest of the joined craters Pallas and Murchison. It lies on a region of raised surface between the Mare Vaporum to the northeast, Sinus Aestuum to the west, and Sinus Medii to the southeast. The crater was named after German astronomer Johann Elert Bode. This crater is bowl-shaped, with a small interior floor and a ridge along the inner wall to the northeast. It has a minor ray system that extends for a distance of 130 kilometers. There is a group of rilles located to the west of the crater named the Rimae Bode. Its name comes from the tap on Bode Faleti discovered in 2011 in Chicago, Illinois. 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 Bode.

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 ...

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 rarel ... [...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 ...

998 Bodea
998 Bodea ( ''prov. designation'': ''or'' ) is a dark background asteroid from the outer regions of the asteroid belt, approximately in diameter. It was discovered on 6 August 1923, by astronomer Karl Reinmuth at the Heidelberg Observatory in southern Germany. The presumed C-type asteroid with an irregular shape has a rotation period of 8.6 hours. It was named after German astronomer Johann Elert Bode (1747–1826). Orbit and classification ''Bodea'' 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 outer asteroid belt at a distance of 2.5–3.8 AU once every 5 years and 6 months (2,012 days; semi-major axis of 3.12 AU). Its orbit has an eccentricity of 0.21 and an inclination of 16 ° with respect to the ecliptic. The body's observation arc begins at Heidelberg on 8 August 1923, just two days after its official discovery observation. Naming ...

Rille
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is ''rima'', plural ''rimae''. Typically, a rille can be several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear a structural resemblance to each other. Structures Three types of rille are found on the lunar surface: * Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. , 195 sinuous rilles have been identified on the Moon. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Elert Bode
Johann Elert Bode (; 19 January 1747 – 23 November 1826) was a German astronomer known for his reformulation and popularisation of the Titius–Bode law. Bode determined the orbit of Uranus and suggested the planet's name. Life and career Bode was born in Hamburg. As a youth, he suffered from a serious eye disease that particularly damaged his right eye; he continued to have trouble with his eyes throughout his life. His early promise in mathematics brought him to the attention of Johann Georg Büsch, who allowed Bode to use his own library for study. He began his career with the publication of a short work on the solar eclipse of 5 August 1766. This was followed by an elementary treatise on astronomy entitled ''Anleitung zur Kenntniss des gestirnten Himmels'' (1768, 10th ed. 1844), the success of which led to his being invited to Berlin by Johann Heinrich Lambert in 1772 for the purpose of computing ephemerides on an improved plan. There he founded, in 1774, the well-known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinus Medii
Sinus Medii (Latin ''sinus mediī'' "Middle Bay") is a small lunar mare. It takes its name from its location at the intersection of the Moon's equator and prime meridian; as seen from the Earth, this feature is located in the central part of the Moon's near side, and it is the point closest to the Earth. From this spot the Earth would always appear directly overhead, although the planet's position would vary slightly due to libration. During the Apollo program, Sinus Medii was designated ALS3. Flight operations planners were concerned about having the optimum lighting conditions at the landing site, hence alternative landing sites moved progressively westward, following the terminator. A delay of two days for weather or equipment reasons would have sent Apollo 11 to Sinus Medii instead of ALS2, Mare Tranquillitatis; another two-day delay would have resulted in ALS5, a site in Oceanus Procellarum, being targeted. Geology The selenographic coordinates of Sinus Medii are , and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinus Aestuum
Sinus Aestuum (Latin ''sinus aestuum'' "Seething Bay") forms a northeastern extension to Mare Insularum. It is centered at selenographic coordinates 12.1° N, 8.3° W, and it lies within a diameter of about 320 km. The Sinus Aestuum is a level, nearly featureless surface of low albedo basaltic lava that is marked by a few small impacts and some wrinkle ridges. The eastern border is formed by an area of irregular terrain that divides the bay from the Mare Vaporum to the east. To the north is the Montes Apenninus range and the prominent crater Eratosthenes. Along the western side is the flooded crater Stadius and the Mare Insularum to the southwest. See also *Volcanism on the Moon Volcanism on the Moon is represented by the presence of volcanoes, pyroclastic deposits and vast lava plains on the lunar surface. The volcanoes are typically in the form of small domes and cones that form large volcanic complexes and isolated ed ... References External links Sinus Aestuuma ...
