Lorentz (crater)
Lorentz is a huge lunar impact crater that lies just beyond the northwest limb of the Moon, in a region that is brought into sight of the Earth during favorable librations. This formation is nearly as large as the Mare Nectaris on the near side of the Moon, although it has not been submerged by lava as have the lunar mare. Sections of the crater floor are, however, relatively level, particularly an arc along the western rim. But this last region is still marked by a number of tiny craterlets. The remainder of the interior is rough and irregular, and marked with a multitude of impacts. Lorentz contains a prominent crater pairing, with Nernst located just to the north of Lorentz's midpoint, and Röntgen attached to the southeastern rim of Nernst. Lying across the southern rim of Lorentz is Laue, and Avicenna lies across the northwestern rim. Near the more indeterminate eastern rim of Lorentz is Aston Aston is an area of inner Birmingham, England. Located immediately to the no ...

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 ...

Röntgen (crater)
Röntgen is a relatively large lunar impact crater that lies along the northwestern limb of the Moon. Its northwestern outer rim is partly overlain by the crater Nernst. Both Nernst and Röntgen overlie the eastern rim of the much larger walled plain Lorentz. The smaller crater Aston Aston is an area of inner Birmingham, England. Located immediately to the north-east of Central Birmingham, Aston constitutes a ward within the metropolitan authority. It is approximately 1.5 miles from Birmingham City Centre. History Aston wa ... is separated from the eastern edge of Röntgen by only a few kilometers of terrain. To the south-southeast is Voskresenskiy. The outer rim of Röntgen has been heavily eroded by subsequent impacts, and it now forms an uneven, jumbled ring of ridges in the surface. There is a relatively fresh, cup-shaped crater along the common rim between Röntgen and Nernst. The interior floor of Röntgen is nearly level, with only a few patches of uneven terrain n ...

Kalmbach Books
Kalmbach Media (formerly Kalmbach Publishing Co.) is an American publisher of books and magazines, many of them railroad-related, located in Waukesha, Wisconsin. History The company's first publication was ''The Model Railroader'', which began publication in the summer of 1933 with a cover date of January 1934. A press release announcing the magazine appeared in August 1933, but did not receive much interest. In 1940, business was good enough for Kalmbach to launch another magazine about railroads in general with the simple title of ''Trains Magazine''. From its first issue dated November 1940, it grew quickly from an initial circulation of just over 5,000. Kalmbach became exclusively a publisher when it discontinued its printing operations in 1973, opting to contract production from other printers. In 1985, Kalmbach purchased AstroMedia Corporation, adding its four magazines: ''Astronomy'', ''Deep Sky'', the children's science magazine ''Odyssey'' and ''Telescope Making'' ...

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 ...

Aston (crater)
Aston is a lunar impact crater that is located along the northwest limb of the Moon. Because of its location the crater is seen nearly from on edge, and visibility is subject to 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 .... It lies to the east of the crater Röntgen, some distance due west of Ulugh Beigh on the edge of the Oceanus Procellarum. To the south is the crater Voskresenskiy. The rim of Aston has been worn down and rounded due to subsequent impacts. It forms a circular shape that has not been significantly altered by nearby impacts. The interior floor is relatively flat and featureless, with no central peak of significance. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoin ...

Avicenna (crater)
Avicenna is a Lunar craters, lunar impact crater that lies on the Far side (Moon), far side of the Moon, just beyond the western limb on the northern rim of the Lorentz (crater), Lorentz basin. It is named after the Persian people, Persian polymath Avicenna. It lies to the north-northwest of the larger crater Nernst (crater), Nernst, and to the southeast of Bragg (crater), Bragg. The northern half of Avicenna has been obliterated by subsequent, overlapping impacts. The southern and southeastern rim is worn and eroded, but the outline can still be discerned. There is a small crater lying across the southern rim, although this formation is equally worn. Several small craters lie across the southern extent of Avicenna's floor. 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 Avicenna.

Laue (crater)
Laue is a Lunar craters, lunar impact crater that lies across the south-southwestern rim and interior floor of the huge walled plain Lorentz (crater), Lorentz. This feature is located on the Moon's Far side (Moon), far side, just beyond the west-northwestern limb. Under conditions of favorable libration and illumination from the Sun, this area can be seen at a very oblique angle from the Earth. This is a moderately worn crater formation with several small craters along the rim. The largest of these is a small crater that intrudes slightly into the northeastern rim. A cup-shaped crater lies along the east-southeastern inner wall. The interior wall is generally less wide along the northern side than elsewhere, which may have been the result of the terrain in which the impact was formed. There is a pair of low central ridges offset just to the south of the crater midpoint. A small, cup-shaped crater lies within the interior floor to the north-northwest of the center. The remainder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nernst (crater)
Nernst is a lunar impact crater that lies on the far side of the Moon, just beyond the northwestern limb. It lies across the northern part of the larger walled plain Lorentz, and intrudes slightly into the northwestern rim of the crater Röntgen. The rim of Nernst is relatively well-defined, although several smaller impacts lies across the edge. The satellite crater Nernst T has broken through the western rim edge. Smaller craters also lie along the rim to the southwest and south-southeast. Around the remainder of the inner wall is some slumping and a few terrace-like features. The interior of Nernst is relatively level, with a central peak formation offset slightly to the south of the midpoint. A pair of small craters lies on the interior floor along the western and southern inner edges. Parts of the remaining floor are marked by a series of rille Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon ...
