Conon (crater)
Conon is a small but prominent lunar impact crater that lies in the eastern foothills of the Montes Apenninus mountain range. The crater is named for the Greek astronomer Conon of Samos ( 250 BCE). Just to the west of Conon is the long mountainous ridge Mons Bradley. The nearest craters possessing an eponym are Galen, about to the east, and Aratus, about the same distance to the northeast. Description The edge of Conon's rim is sharply defined and has not received significant erosion from later impacts. The inner wall is somewhat variable in width, and the interior floor forms an irregular oval shape. This irregularity may be due to the rough and uneven surface on which the crater was formed. The floor is rough, but lacks a central prominence of note. To the south, in the Sinus Fidei, is a sinuous rille that follows a course to the south-southeast. This rille is designated Rima Conon, and is named after this crater. Satellite craters By convention these features are identif ...

Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans (astronaut), Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a Fe, Fi, Fo, Fum, and Phooey, biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample Lunar highlands, lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent Volcano, volcanic activity. They therefore selected Taurus– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conon Sattelite Craters Map
Conon ( el, Κόνων) (before 443 BC – c. 389 BC) was an Athenian general at the end of the Peloponnesian War, who led the Athenian naval forces when they were defeated by a Peloponnesian fleet in the crucial Battle of Aegospotami; later he contributed significantly to the restoration of Athens' political and military power. Defeat at Aegospotami Conon had been sent out to lead the Athenian forces following the recall of Alcibiades in 406 BC, and in 405 BC pursued the Peloponnesian fleet under Lysander to the Hellespont. Once there, the Peloponnesian took up a strong defensive position at Lampsacus and as they could not lure them out, the Athenians retreated to Aegospotami. Alcibiades came to warn them of the danger of their position, as they were based on an open beach without harbours, and advised them to move to Sestos about two miles away from where they were retrieving supplies. It seems that Alcibiades' advice was ignored and perhaps ridiculed. On the fifth day of ... [...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 campaigne ...

Rima Conon AS17-M-1674
Rima, also known as Rima the Jungle Girl, is the fictional heroine of W. H. Hudson's 1904 novel '' Green Mansions: A Romance of the Tropical Forest''. In it, Rima, a primitive girl of the shrinking rain forest of South America, meets Abel, a political fugitive. A film adaptation of ''Green Mansions'' was made in 1959 starring Audrey Hepburn. In 1974, the character was adapted into the comic book ''Rima the Jungle Girl'', published by DC Comics. Though ''Rima the Jungle Girl'' ceased publication in 1975, the comic book version of Rima appeared in several episodes of Hanna-Barbera's popular Saturday morning cartoon series, ''The All-New Super Friends Hour'', between 1977 and 1980. Novel Like her literary cousins Tarzan and Mowgli, Rima sprang from an Edwardian adventure novel; in her case, '' Green Mansions: A Romance of the Tropical Forest'', by W. H. Hudson, published in 1904. Hudson was an Argentine-British naturalist who wrote many classic books about the ecology of South Am ...

Rille
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is ''rima'', plural ''rimae''. Typically, a rille can be several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear a structural resemblance to each other. Structures Three types of rille are found on the lunar surface: * Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. , 195 sinuous rilles have been identified on the Moon. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aratus (crater)
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. It was named after Greek astronomer Aratus of Soli. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon. North-northeast of Aratus is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta. 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 Aratus. The following craters have been renamed by the IAU. * Aratus A—''See'' Galen (crater). File:Aratus D crater hrp215.jpg, Aratus D (center) and probable collapse features to the east, associated with a small rille (arrows) Aratus CA This three-pronged feature is located in western Mare Serenitatis.

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. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...
