Moseley (crater)
Moseley is a worn lunar impact crater that lies along the western limb of the Moon. It lies just to the south of the crater Bartels, and near the north-northeastern rim of Einstein. Due to its location, this crater is viewed side-on from Earth, and not much detail can be seen. It can also become hidden from sight due to the effects of 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 tim .... The outer rim of this feature has been worn and eroded due to subsequent impacts. Little of the original rim remains intact, and the perimeter is generally an irregular circular ridge surrounding the interior floor. In contrast the floor of the crater is relatively level and featureless. There are only a few tiny craterlets marking the surface. References * * * * * * * * * * * ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, 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 Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...

Henry Gwyn Jeffreys Moseley
Henry Gwyn Jeffreys Moseley (; 23 November 1887 – 10 August 1915) was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's law advanced atomic physics, nuclear physics and quantum physics by providing the first experimental evidence in favour of Niels Bohr's theory, aside from the hydrogen atom spectrum which the Bohr theory was designed to reproduce. That theory refined Ernest Rutherford's and Antonius van den Broek's model, which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its (atomic) number in the periodic table. This remains the accepted model today. When World War I broke out in Western Europe, Moseley left his research work at the University of Oxford behind to volunteer for the Royal Engineers of the British A ...

Moseley Crater LROC WAC
Moseley is a suburb of south Birmingham, England, south of the city centre. The area is a popular cosmopolitan residential location and leisure destination, with a number of bars and restaurants. The area also has a number of boutiques and other independent retailers. It is located within the Moseley and Kings Heath Ward of the city, in the constituency of Hall Green. Historically it lay within Worcestershire. History Moseley was listed in the Domesday Book of 1086 as Museleie. St. Mary's Church, Moseley was licensed by the Bishop of Worcester (authorised by Pope Innocent VII) in February 1405, and the 600th anniversary was celebrated in 2005 with a series of special events. In 2012 the church bells which had been named as the worst sounding in the country were replaced. Moseley itself developed around a Victorian shopping area known as ''Moseley Village''. Moseley Hall was rebuilt in parkland in the late 1700s and rebuilt by 1795 after being set on fire during rioti ... [...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 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] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity 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. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, 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, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bartels (crater)
Bartels is a lunar impact crater located along the western perimeter of the Moon's visible face. At this location the crater is viewed from the side, and visibility is affected by libration. The crater can be viewed in its entirety only from lunar orbit. It is located to the north of the crater Moseley Moseley is a suburb of south Birmingham, England, south of the city centre. The area is a popular cosmopolitan residential location and leisure destination, with a number of bars and restaurants.

The rim of this crater is worn and eroded, particularly along the southern face and in the northeast where a small crater overlies the rim. The interior floor forms a nearly plain except for a tiny central peak offset to the west of the midpoint, and is marked by a number of tiny craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the ... [...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. Occupying the center of the interior floor is Einstein A, an impact crater with wiktionary:terrace, terraced inner walls and a central peak. The ...

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 ...
