To the southwest is the heavily battered crater Tikhomirov. This is an old, eroded crater with an outer rim that has been damaged in places by subsequent impacts, especially along the southwestern section. The rim edge has been worn to the point where it is now poorly defined, and forms an uneven ridge in the surface. A short chain of small craterlets extends from near the crater midpoint to just outside the eastern rim. The ... [...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 orbit, 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 LCROSS, 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. ...

Robert Julius Trumpler
Robert Julius Trumpler (October 2, 1886 – September 10, 1956) was a Swiss-American astronomer. Career Born in Switzerland in October 2, 1886, where Trumpler did initial schooling. Trumpler entered the Universität Zürich but later transferred to the University of Göttingen where he earned his PhD in 1910. In 1915, during World War I, he emigrated to the United States and joined the University of California. He took a position at Allegheny Observatory, and later went to Lick Observatory. In 1921, he became a naturalized citizen of the United States. He was elected a member of the United States National Academy of Sciences in 1932. He is most noted for observing that the brightness of the more distant open clusters was lower than expected, and the stars appeared more red. This was explained by the interstellar dust scattered through the galaxy, resulting in the absorption (extinction) of light or interstellar extinction of light. Trumpler further studied and catalogued open ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek language, Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his refracting telescope, first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far Side (Moon)
The far side of the Moon is the hemisphere of the Moon that is facing away from Earth, the opposite hemisphere is the Near side of the Moon, near side. It always has the same surface oriented away from Earth because of synchronous rotation in the Moon's Orbit of the Moon, orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar mare, lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury (planet), Mercury and Callisto (moon), Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere has sometimes been called the "Dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each location on the Moon experiences two weeks of sunlight while the opposite location experiences night. About 18 percent of the far side is occasionally visible from Earth due to oscillatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freundlich (crater)
Freundlich is a Lunar craters, lunar impact crater that is located on the Far side (Moon), far side of the Moon. It lies midway between the craters Trumpler (lunar crater), Trumpler to the north-northwest and the irregular Buys-Ballot (crater), Buys-Ballot to the south-southeast. This crater has a circular rim that is more heavily eroded at the northern and southern ends. Groups of craters lie across the floor to the southeast and the north, and individual small craters lie elsewhere within the interior. The crater was named after Erwin Freundlich by the IAU in 1970. The crater lies within the Freundlich-Sharonov Basin. 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 Freundlich.
