Ariadaeus (crater)
Ariadaeus is a small, bowl-shaped lunar impact crater on the western shores of Mare Tranquillitatis. It lies to the north of the crater Dionysius, and to the west-southwest of Arago. The crater is joined along the northeast rim by the slightly smaller Ariadaeus A, and the two form a double-crater. Its diameter is 10.4 km. This crater marks the eastern extent of the rille designated Rima Ariadaeus. This wide rille extends in a nearly straight line to the west-northwest, passing just to the north of the crater Silberschlag. Other rille systems lie in the vicinity, including the Rimae Ritter to the southeast and Rimae Sosigenes to the northeast. The crater was named after Philip III of Macedon Philip III Arrhidaeus ( grc-gre, Φίλιππος Ἀρριδαῖος ; c. 359 BC – 25 December 317 BC) reigned as king of Macedonia an Ancient Greek Kingdom in northern Greece from after 11 June 323 BC until his death.

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 ...

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] |

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 ...

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 ...

Silberschlag (crater)
Silberschlag is a small, circular Impact crater in the central portion of the Moon. It was named after German astronomer Johann Silberschlag. It lies between the craters Agrippa to the southwest and Julius Caesar to the northeast. Silberschlag is bowl-shaped and is joined at the northern rim by a small ridge. Just to the north is the prominent Rima Ariadaeus, a wide, linear rille that runs toward the east-southeast. This cleft is about 220 kilometers in length, and continues to the edge of Mare Tranquillitatis Mare Tranquillitatis (Latin ''tranquillitātis'', the Sea of Tranquillity or Sea of Tranquility; see spelling differences) is a lunar mare that sits within the Tranquillitatis basin on the Moon.

Rima Ariadaeus
Rima Ariadaeus is a linear rille on the Moon at . It is named after the crater Ariadaeus (crater), Ariadaeus, which marks its eastern end. It is over 300 km long and is categorized as a straight rille because of its linear nature. Formation Some scientists think that the linear rilles might have formed after large impact events, while others believe that the rilles were formed as a surface manifestation of deep-seated dike systems when the Moon was still volcanically active. Rima Ariadaeus is thought to have been formed when a section of the Moon's crust sank down between two parallel fault lines (making it a graben or fault trough). Rima Ariadaeus shows no trace of associated volcanism and is thus considered to be an end member of the sequence where only pure faulting is involved i.e. a linear rille. Age The ridges crossing the rille trough of Rima Ariadaeus and the surrounding plains units have been offset by the trough, proving that the ridges are older than the faul ...

Rima Ariadaeus-1
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 ...

Philip III Of Macedon
Philip III Arrhidaeus ( grc-gre, Φίλιππος Ἀρριδαῖος ; c. 359 BC – 25 December 317 BC) reigned as king of Macedonia an Ancient Greek Kingdom in northern Greece from after 11 June 323 BC until his death. He was a son of King Philip II of Macedon by Philinna of Larissa, and thus an elder half-brother of Alexander the Great. Named Arrhidaeus at birth, he assumed the name Philip when he ascended to the throne. As Arrhidaeus grew older it became apparent that he had mild learning difficulties. Plutarch was of the view that he became disabled by means of an attempt on his life by Philip II's wife, Queen Olympias, who wanted to eliminate a possible rival to her son, Alexander, through the employment of ''pharmaka'' (drugs/spells); however, most modern authorities doubt the truth of this claim. Alexander was fond of Arrhidaeus and took him on his campaigns, both to protect his life and to prevent his use as a pawn in any prospective challenge for the throne. After ...

Dionysius (crater)
Dionysius is a lunar impact crater that lies on the western edge of the Mare Tranquillitatis. It was named after Dionysius the Areopagite. To the southeast is the crater pair of Ritter and Sabine. Just to the northwest is the system of rilles designated Rimae Ritter. These clefts follow a generally northwest direction. The rim of Dionysius is generally circular and shows little sign of wear. The crater possesses a small ray system with a radius of over 130 kilometers. The formation has a high albedo and appears bright when the Sun is nearly overhead during a full Moon. It is surrounded by a bright halo, with darker material farther out. Some darker deposits are in the form of relatively rare dark rays. 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 Dionysius.
