Vasco Da Gama (crater)
Vasco da Gama is a lunar impact crater that is located near the western limb of the Moon. It is named for the Portuguese explorer Vasco da Gama. It lies to the south of the walled plain Einstein, due south of Dalton. Attached to the southwestern rim of Vasco da Gama is the somewhat smaller crater Bohr. The northern and southern parts of the rim of Vasco da Gama have been heavily eroded by impacts, with the western and eastern rims being more intact. The smaller crater Vasco da Gama S intrudes into the southeastern rim, and just to its southwest is Vasco da Gama T. Near the northeastern rim is Vasco da Gama B. There is a low central massif near the midpoint of the interior. The interior floor of satellite crater Vasco da Gama R contains a system of 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 sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bohr (crater)
Bohr is a lunar impact crater that is located near the western lunar limb, in the area that is affected by librations. It is attached to the southwestern rim of the larger, eroded Vasco da Gama formation, and to the southeast of the crater Einstein. The crater was observed for the first time in 1963, by Arthus and Ewen Whitaker in the book ''Rectified Lunar Atlas.http://planetarynames.wr.usgs.gov/] The rim of Bohr is worn and eroded, and a pair of small, bowl-shaped craters lies across the western rim. The rim to the northeast has been shored up by the adjacent Vasco da Gama, but the remainder forms an irregular ring of rugged ground. To the southwest of Bohr is Vallis Bohr, a valley trending in a north–south direction. This long cleft is most likely associated with the formation of the Mare Orientale Mare Orientale (Latin ''orientāle'', the "eastern sea") is a lunar mare. It is located on the western border of the near side and far side of the Moon, and is difficult to se ... [...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 ...

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] |

Vasco Da Gama
Vasco da Gama, 1st Count of Vidigueira (; ; c. 1460s – 24 December 1524), was a Portuguese explorer and the first European to reach India by sea. His initial voyage to India by way of Cape of Good Hope (1497–1499) was the first to link Europe and Asia by an ocean route, connecting the Atlantic and the Indian oceans. This is widely considered a milestone in world history, as it marked the beginning of a sea-based phase of global multiculturalism. Da Gama's discovery of the sea route to India opened the way for an age of global imperialism and enabled the Portuguese to establish a long-lasting colonial empire along the way from Africa to Asia. The violence and hostage-taking employed by da Gama and those who followed also assigned a brutal reputation to the Portuguese among India's indigenous kingdoms that would set the pattern for western colonialism in the Age of Exploration. Traveling the ocean route allowed the Portuguese to avoid sailing across the highly disputed Medit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Einstein (crater)
Einstein is a large lunar impact crater that lies along the western limb of the Moon, which makes it difficult to observe from the Earth. The visibility of this formation is subject to libration effects, but even under the best conditions not much detail can be observed except from lunar orbit. Nearby craters of note include Moseley just to the north, Dalton along the eastern rim, Vasco da Gama just to the southeast, and Bohr to the south-southeast. The formation Vallis Bohr Vallis Bohr is a valley on the Moon stretching due south of the crater Einstein. This wide cleft has a length of about 80 kilometers, and is radial to the Mare Orientale impact basin further to the south. The selenographic coordinates of this fe ... is visible to the south. The outer rim of this walled plain has been strongly obliterated by many smaller impacts.
