Flammarion (lunar Crater)
Flammarion is a lunar impact crater on the south edge of Sinus Medii. Its diameter is 76 km. It is named after the French astronomer Camille Flammarion. It is located between the crater Mösting to the northwest and Herschel to the southeast. The bowl-shaped Mösting A intersects the western rim of Flammarion. The worn outer wall of Flammarion is broken in the northwest, and the remainder is eroded and damaged. The most intact section of the wall lies to the southeast. A rille designated Rima Flammarion lies across the gap in the northwest rim, extending about 80 kilometers to the west-southwest. The crater floor has been flooded by lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or un ..., and is relatively smooth with only a few scattered craterlets to mark the surface. ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for 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 cislunar trajectory and injected into an elliptical near polar high lunar orbit In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...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 ...

1021 Flammario
1021 Flammario, provisional designation , is a dark background asteroid from the central regions of the asteroid belt, approximately in diameter. It was discovered on 11 March 1924, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in Heidelberg, Germany. The asteroid was named after French astronomer Camille Flammarion. The uncommon F-type asteroid has a rotation period of 12.16 hours. Orbit and classification ''Flammario'' is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 2.0–3.5 AU once every 4 years and 6 months (1,654 days; semi-major axis of 2.74 AU). Its orbit has an eccentricity of 0.29 and an inclination of 16 ° with respect to the ecliptic. The asteroid was first observed as at Taunton Observatory in February 1910.

Flammarion (Martian Crater)
Flammarion is an impact crater in the Syrtis Major quadrangle on Mars at 25.2 ° N and 48.3 ° E. It is 173.0 km in diameter. Its name was approved in 1973, and refers to French astronomer Camille Flammarion. There may have been a lake in the crater in the past because a channel is present on the northern rim, and sedimentary layers are present within the crater. Description Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. Sometimes the layers are of different colors. Light-toned rocks on Mars have been associated with hydrated minerals like sulfates. The Mars Rover Opportunity examined such layers close-up with several instruments. Some layers are probably made up of fine particles because they seem to break up into fine dust. Other layers break up into large boulders so they are probably much harder. Basalt, a volcanic rock, is thought to be present in the layers that form bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camille Flammarion
Nicolas Camille Flammarion FRAS (; 26 February 1842 – 3 June 1925) was a French astronomer and author. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and works on psychical research and related topics. He also published the magazine '' L'Astronomie'', starting in 1882. He maintained a private observatory at Juvisy-sur-Orge, France. Biography Camille Flammarion was born in Montigny-le-Roi, Haute-Marne, France. He was the brother of Ernest Flammarion (1846–1936), the founder of the Groupe Flammarion publishing house.

Herschel (lunar Crater)
Herschel is a lunar impact crater located just to the north of the walled plain Ptolemaeus. Its diameter is 39 km. It was named after German-born British astronomer William Herschel. Just to the north is the flooded crater Spörer, and around 30 km due east lies the disintegrated crater Gyldén. About a crater diameter to the northwest (35 km) is the walled plain Flammarion, along the southern edge of the Sinus Medii. The rim of this crater is generally circular, although the western side is straight. It has a well-defined edge that is not significantly worn, and the inner walls are terraced. On the rough inner floor is a notable central rise. This peak is offset slightly to the west of the crater midpoint. The small crater Herschel G is attached to the south-southwest rim, and a tiny craterlet lies across the southern rim. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that ...
