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 area also has a number of boutiques and ot ... and south-southeast of Voskresenskiy. 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] |
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 ...

Julius Bartels
Julius Bartels (17 August 1899, Magdeburg – 6 March 1964) was a German geophysicist and statistician who made notable contributions to the physics of the Sun and Moon; to geomagnetism and meteorology; and to the physics of the ionosphere. He also made fundamental contributions to statistical methods for geophysics. Bartels was the first President of the International Association of Geomagnetism and Aeronomy (IAGA). With Sydney Chapman, he wrote the influential book '' Geomagnetism''. Life and career Bartels was awarded his Ph.D. from Göttingen in 1923, then worked at the Potsdam magnetic observatory as a post-doctorate. In 1928, he was named professor at Eberswalde, teaching meteorology. He became full professor at Berlin University in 1936, and director of the Potsdam Geophysical Institute. From 1931 until the second year of World War II, he was also a research associate at the Carnegie Institution of Washington. He collaborated with Sydney Chapman to publish the two-volume ...

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] |
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 ...

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 * * * * * * * * * * * ...

Voskresenskiy (crater)
Voskresenskiy is a lunar impact crater that is located near the western limb of the Moon. Due to its position, this crater is viewed edge-on, limiting the amount of detail that can be viewed. The visibility of this formation is also affected by libration, so that at times this crater is hidden from sight, while at other times it can be more readily viewed. The crater is located to the southeast of the walled plains Röntgen and Lorentz. To the south-southwest lies the crater Bartels, and slightly farther to the east is the western edge of the Oceanus Procellarum. The outer edge of this crater is only slightly worn, and the edge is still well-defined with only a few tiny craterlets lying along the southwestern rim. A small crater is attached to the exterior edge of the rim to the southeast. The inner wall has a shelf or terrace along the northern and western sides. The dark interior floor has been resurfaced by basaltic lava Lava is molten or partially molten rock (magma) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
