Dubyago (crater)
Dubyago is a lunar impact crater that lies in the eastern limb of the Moon. It was named after Russian astronomers Dmitry Dubyago and Alexander Dubyago. It appears significantly foreshortened when viewed from the Earth. It lies along the southern shore of the Mare Undarum, to the southeast of the crater Firmicus. This crater has a somewhat worn outer rim which dips down to a low point along the northern rim, and has its maximum altitude along the eastern side. The most notable aspect of this crater, however, is the dark hue of the interior floor which matches the albedo of the lunar mare to the northwest. This darker shading makes the crater stand out somewhat from its surroundings. Dubyago has an unusual number of satellite craters, several of which have since been given names by the IAU. The most notable of these is Dubyago B, which is nearly attached to the southeastern rim of the main crater. The name of this crater has also been spelled ''Dubiago'' in some publications. ...

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments co ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 campaig ...

Boethius (lunar Crater)
Boethius is a small lunar impact crater located on the east edge of Mare Undarum near the eastern lunar limb. To the southwest is the dark, lava-flooded crater Dubyago. Boethius is circular and cup-shaped, with inner walls sloping down to the tiny central floor. It has a higher albedo than the surrounding terrain, and is not overlain by other impact craters of note. It was named after the Roman philosopher Boethius. Before 1976, it was identified as Dubyago U.

Liouville (crater)
Liouville is a small lunar impact crater that is located near the eastern limb of the Moon. It was named after French mathematician Joseph Liouville. It lies to the southeast of the larger crater Dubyago, and was previously designated Dubyago S before being given a name by the IAU. The crater is circular and bowl-shaped, with a small interior floor at the midpoint of the sloping interior walls.

Stewart (crater)
Stewart is a small lunar impact crater that lies to the northeast of the Mare Spumans, a small lunar mare near the eastern limb of the Moon. It was named after American astrophysicist John Quincy Stewart. It is located to the north of the crater Pomortsev, and to the southwest of the lava Lava is molten or partially molten rock ( magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or ...-flooded Dubyago. Stewart was previously designated Dubyago Q before being named by the IAU.

Pomortsev (crater)
Pomortsev is a small lunar impact crater that is located in the eastern part of the Moon's near side. It was named after Russian rocketry scientist Mikhail Pomortsev. It lies on the eastern edge of Mare Spumans, to the southwest of the crater Dubyago. This formation was previously designated Dubyago P. One crater diameter to the north is the smaller Stewart. The nearly featureless interior of this crater has been resurfaced by basaltic lava, leaving a dark floor with an albedo that nearly matches the lunar mare to the west. The crater it roughly circular, with slight outward bulges to the north and northeast. The inner wall is wider along the southern half of the rim, and at its narrowest along the northwestern rim where the crater makes contact with Mare Spumans.

Respighi (crater)
Respighi is a small lunar impact crater that is located to the southeast of the crater Dubyago, near the eastern limb of the Moon. To the east is the comparably sized Liouville. This is a crudely circular crater with inner walls that slope down to the relatively darker (lower albedo) interior central floor. The rim has not suffered significant erosion from subsequent impacts, but there is a shallower section to the south. Attached to the southern rim of this crater is Schubert N, a formation that has the appearance of two or more merged craters with a dark, lava-flooded floor that is elongated to the southeast. The crater is named for Lorenzo Respighi, 1824–89, Italian mathematician and astronomer.
