Ginzel (crater)
Ginzel is a lunar impact crater that is located on the far side of the Moon, just beyond the eastern limb. It is named after the Austrian astronomer Friedrich Karl Ginzel. It lies at the eastern edge of the Mare Marginis, in a region of the surface that is sometimes brought into sight of the Earth due to libration. To the north-northeast of Ginzel is the crater Popov, and Dreyer Dreyer is a common German surname originating from Grübe in Holstein Germany. Notable people with the surname include: * Benjamin Dreyer (1958– ), American writer and copy editor * Benedikt Dreyer (1495–1555), German sculptor, carver and pai ... lies due south. Much of the rim and interior of Ginzel have been flooded, leaving only a faint trace of the rim in the otherwise relatively level surface. The western rim projects more prominently above the surrounding irregular plain. The flooded satellite crater Ginzel L is attached to the southern part of the rim, and a small craterlet lies across the rim ...

Friedrich Karl Ginzel
Friedrich Karl Ginzel (26 February 1850 – 29 June 1926) was an Austrian astronomer. From 1877 Ginzel worked at the observatory in Vienna. In 1886, he became a member of the Königlichen Astronomischen Recheninstituts in Berlin, where he was offered a professorship in 1899. In 1899 he published an important study on Solar eclipse , solar and Lunar eclipse , lunar eclipses in classical antiquity. His three-volume ''Handbuch der mathematischen und technischen Chronologie'' (1906–14; reprinted in 1958 and 2007) is still a standard work on calendars and ancient chronology although some sections are now outdated. He was awarded the Valz Prize by the French Academy of Sciences in 1884 for his work on solar eclipses. The lunar crater Ginzel (crater), Ginzel was named after him.

Popov (crater)
Popov is a Impact crater, crater on the Far side (Moon), far side of the Moon, just beyond the eastern limb. It measures approximately in diameter and is located along the very edge of the area of surface that is sometimes brought into view of the Earth during periods of favorable libration and illumination. However even at such times it is not prominent and can only be viewed edge-on. Description This crater lies due south of Dziewulski (crater), Dziewulski, and the crater chain designated Catena Dziewulski passes just to the northeast of Popov's outer rim. Just to the southeast of Popov lies Möbius (crater), Möbius, and the two are joined together by a smaller crater that lies along the south-southeast rim of Popov. To the southwest lies the crater Ginzel (crater), Ginzel and Mare Marginis. Popov is a worn crater with a damaged outer rim that is little more than a circular, jumbled series of ridges in the surface. Several small craterlets lie along the rim and inner wall, ...

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 ...

Dreyer (crater)
Dreyer is the remnant of a Lunar craters, lunar impact crater on the Far side (Moon), far side of the Moon. It is located along the eastern edge of the Mare Marginis, about midway between the craters Ginzel (crater), Ginzel to the north and Erro (crater), Erro to the south-southeast. It was named after Danish-Irish astronomer John Louis Emil Dreyer, John L. E. Dreyer. The rim of this crater is heavily worn, with multiple impacts overlaying the edge and a small gap at the south end. The satellite crater Dreyer C lies across the northeastern rim, while Dreyer K intrudes into the southeastern side. The interior floor is relatively level and featureless, with a few tiny craterlets marking the surface. There is a low central ridge at the midpoint. 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 Dreyer.

Libration
In lunar astronomy, libration is the wagging or wavering of the Moon perceived by Earth-bound observers and caused by changes in their perspective. It permits an observer to see slightly different hemispheres of the surface at different times. It is similar in both cause and effect to the changes in the Moon's apparent size due to changes in distance. It is caused by three mechanisms detailed below, two of which cause a relatively tiny physical libration via tidal forces exerted by the Earth. Such true librations are known as well for other moons with locked rotation. The quite different phenomenon of a trojan asteroid's movement has been called ''Trojan libration''; and ''Trojan libration point'' means Lagrangian point. Lunar libration The Moon keeps one hemisphere of itself facing the Earth, due to tidal locking. Therefore, the first view of the far side of the Moon was not possible until the Soviet probe Luna 3 reached the Moon on October 7, 1959, and further lunar exp ...

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 word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his 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. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mare Marginis
Mare Marginis (Latin ''marginis'', the "Sea of the Edge") is a lunar mare that lies on the very edge of the lunar nearside. The selenographic coordinates of this feature are 13.3° N, 86.1° E, and the diameter is 358 km. The name is Latin for "Sea of the Edge". This mare differs from most of the nearside maria; it has an irregular outline and it appears to be fairly thin. It has small circular and elongated features in the mare plains that probably mark impact craters buried by less than 1000 to 1700 feet (300 to 500 m) of lava. Further, Mare Marginis is not centered on any clear, large impact basin. Thus, Mare Marginis seems to mark a low-lying region of the highlands where mare lavas were just able to reach the surface. Several large mare-floored craters also occur nearby. In these craters, the crater floors lie below the surrounding highland surface. Thus, they mark sites around Mare Marginis where lavas were close to the lunar surface. The major crater to the north of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
