Wan-Hoo (crater)
Wan-Hoo is a lunar impact crater that is located on the Moon's far side, and it cannot be seen directly from the Earth. It lies to the southwest of the huge walled plain Hertzsprung, within the outer skirt of ejecta. Just to the south-southwest of Wan-Hoo is the larger crater Paschen, and a little over two crater diameters to the northwest is Sechenov. Like much of the surrounding terrain, this crater has been modified by the ejecta from Hertzsprung, and material from that impact encroaches along the inner walls and interior of Wan-Hoo. Attached to the east-southeastern outer rim is a large satellite crater, Evans Q, belonging to Evans farther to the east. There is also a small, relatively fresh crater attached to the southeast, and a small, cup-shaped craterlet along the western rim. This feature was named after Wan Hu, a legendary Chinese figure who is alleged to be the first astronaut An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sail ...

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. ...

Sechenov (crater)
Sechenov is a lunar impact crater on the far side of the Moon. It lies to the southwest of the huge walled plain Hertzsprung, and to the east-southeast of the crater Timiryazev. To the south-southeast of Sechenov lies Paschen. This crater has taken a moderate amount of wear and tear as a result of subsequent impacts. The outer rim is somewhat worn and uneven. There is a small crater intruding into the southwestern outer rim. A joined pair of small craters is located in the middle of the interior floor, and there is a small craterlet along the eastern base of the inner wall. Sechenov is a crater of Nectarian age. USGS

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a List of human spaceflight programs, human spaceflight program to serve as a commander or crew member of a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and space tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek ). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Standard Chinese, Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evans (crater)
Evans is the remnant of a lunar impact crater that is located on the far side of the 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 .... It lies to the south-southwest of the immense walled plain Hertzsprung, and is located within that impact basin's broad skirt of ejecta. This material has overflowed the northern rim of Evans and the northern part of the interior floor. The southern rim is not as heavily damaged, although it is irregular, eroded, and overlain by a pair of small craterlets. The most intact part of the rim is the southeastern section. 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 Evans.

Paschen (crater)
Paschen is a Lunar craters, lunar impact crater on the Far side (Moon), far side of the Moon. The relatively large satellite crater Paschen M partly overlies the southern rim of Paschen, and they nearly form a merged pair with only a section of irregular terrain along their common border. The smaller but well-formed crater Paschen S lies across the southwestern rim of Paschen. As a result, most of the southern rim of Paschen is now gone. The remainder of the rim is not in much better condition. It is worn and eroded, with multiple small craterlets along the edge and inner wall. Most of the rim structure has been worn away by subsequent impacts and deposits of ejecta, and now forms a rounded dip into the curving interior. A small chain of craters cuts across the rim and inner wall to the west-northwest. There are several small craterlets in the southeastern part of the floor. Paschen lies to the east of the larger walled plain Galois (crater), Galois, and to the southwest of the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wan Hu
Wan Hu is a legendary Chinese official described in modern sources as possibly the first man to attempt to use a rocket to launch into outer space. Possibly depicted as the "world's first astronaut" and "the first martyr in man's struggle to achieve space flight", NASA named the crater Wan-Hoo on the far side of the Moon after him. According to some Chinese sources, "Wan Hu" was a title granted to him by the imperial court during the early Ming dynasty, and his real name was Tao Chengdao. As a Ming official, he was interested in technological innovation, particularly concerning rockets. He is said to have died in 1390. While the legend is well-known, there is no direct evidence surviving to substantiate it. According to Joseph Needham, the story is dubious and may be invented during or after the ''Chinoiserie'' period, considering the lack of firm historical reference. However, Li Chengzhi has argued for the story's plausibility, saying that it may have come from oral transmiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertzsprung (crater)
Hertzsprung is an enormous Lunar craters, lunar impact crater, or impact basin, that is located on the Far side (Moon), far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin. Nearby craters of note include Michelson (crater), Michelson across the northeast rim, Vavilov (crater), Vavilov across the western rim, and Lucretius (crater), Lucretius to the southeast. Hertzsprung is a basin of Nectarian age. The outer rim of Hertzsprung has been damaged and modified by several notable impacts (mentioned above) and a number of smaller craters. A chain of small craters, designated Catena Lucretius, begins at the southeastern outer rim and proceeds toward the west-northwest until it connects with the perimeter of the inner basin. This inner area is less rough than the outer ring of the floor, and is surrounded by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
