Guyot (crater)
Guyot is a lunar impact crater on the Moon's far side. It is separated from the crater Kostinskiy to the northeast by only a few kilometers of rough terrain. To the west-southwest lies the crater Lobachevskiy and to the east-southeast is Ostwald. This is a worn and eroded crater with an outer rim that has been somewhat distorted in shape due to nearby impacts. Several small craterlets lie along the rim and the sides. The interior floor has also been marked by impacts, including an eroded formation occupying the northwestern portion. The crater is named after the Swiss-born American geographer and geologist Arnold Henry Guyot. Prior to naming in 1970 by the IAU, this crater was known as ''Crater 208''. 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 Guyot.

Apollo 16
Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's " J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to E ...

Ostwald (crater)
Ostwald is a lunar impact crater on the far side of the Moon. It lies just to the east of the crater Guyot, and near the northern border of Ibn Firnas. Recht lies along its eastern rim. This is a worn and eroded crater formation with an irregular rim and inner wall due to multiple small impacts. A brief crater chain forms a cleft in the western inner face. The interior is somewhat more level, but is pock-marked by a multitude of tiny craterlets. There are some low central ridges to the south and northeast of the midpoint. Naming The crater is named after German chemist and Nobel laureate Wilhelm Ostwald Friedrich Wilhelm Ostwald (; 4 April 1932) was a Baltic German chemist and philosopher. Ostwald is credited with being one of the founders of the field of physical chemistry, with Jacobus Henricus van 't Hoff, Walther Nernst, and Svante Arrhen .... Prior to naming in 1970 by the IAU, this crater was known as ''Crater 212''. Satellite craters By convention these features a ...

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 ...

Lobachevskiy (crater)
Lobachevskiy is a lunar impact crater that is located on the far side of the Moon, beyond the eastern limb. It was named after Russian mathematician Nikolai Lobachevsky in 1961. This crater lies to the southeast of the larger crater Fleming. Less than a crater diameter to the east-northeast lies Guyot. This is a well-formed crater with features that have not been significantly eroded since Lobachevskiy was first formed. The rim and inner wall are nearly free of significant overlapping impacts, although the satellite crater Lobachevskiy M is attached to the southern outer rim. The inner walls display terrace features, along with some slumping along the upper edge. Near the midpoint of the interior floor is a pair of central peaks, with one to the southeast and the other to the northwest of the middle. To the east of these peaks is a relatively bright, high-albedo patch that is most likely the result of a recent small impact. Two dark ribbons of material apparently emanate from ...

Arnold Henry Guyot
Arnold Henry Guyot ( ) (September 28, 1807February 8, 1884) was a Swiss-American geologist and geographer. Early life Guyot was born on September 28, 1807, at Boudevilliers, near Neuchâtel, Switzerland. He was educated at Chaux-de-Fonds, then at the college of Neuchâtel. In 1825, he went to Germany and resided in Karlsruhe where he met Louis Agassiz, the beginning of a lifelong friendship. From Karlsruhe he moved to Stuttgart, where he studied at the gymnasium. He returned to Neuchâtel in 1827. He determined to enter the ministry and started at the University of Berlin to attend lectures. While pursuing his studies, he also attended lectures on philosophy and natural science. His leisure time was spent in collecting shells and plants, and he received an entrée to the Berlin Botanical Garden from Humboldt. In 1835, he received the degree of PhD from Berlin. Scientific career In 1838, at Agassiz's suggestion, he visited the Swiss glaciers and communicated the results o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kostinskiy (crater)
Kostinsky is a lunar impact crater on the far side of the Moon. It is nearly attached to the northeastern outer rim of the crater Guyot. About one crater diameter to the southeast is Ostwald Ostwald may refer to: * Friedrich Wilhelm Ostwald, the physico-chemist (awarded the Nobel Prize in Chemistry, 1909) # Ostwald's rule of polymorphism: in general, the least stable polymorph crystallizes first # The Ostwald Process, a synthesis met ..., and farther to the north is Olcott. The rim of Kostinsky is eroded, and along the southeast has been nearly worn away. The rim has an outward bulge along the northeastern side. There is a small crater intruding into the eastern rim. The interior floor has some irregularities in the southwest quadrant, and along the edge of the bulging section to the northeast. The crater was named after the Russian astronomer Sergey Kostinsky in 1970. Prior to that, this crater was known as ''Crater 210''. Satellite craters By convention these features ar ...

Far Side (Moon)
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Soviet Luna 3 space probe. The Soviet Academy of Sciences published the ...
