Barbier (crater)
Barbier is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It forms a matched pair with Cyrano to the north-northwest, and it lies to the southeast of the huge walled plain Gagarin. Southwest of Barbier is the crater Sierpinski, and to the southeast is the Mare Ingenii Mare Ingenii (Latin ''ingeniī'', the "Sea of Cleverness") is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin, which is of the Pre-Nectarian epoch, which lies in turn in the outer part of the old .... The outer rim of Barbier has been eroded somewhat by subsequent impacts, particularly at the north end where the wall has been degraded by several small craterlets. A small crater lies across the eastern rim, and the southern rim is wider and irregular in shape. An unusual irregular crater (Barbier F) with a hummocky floor, approximately 16 km long, lies near where a central peak would be located, offset to the eas ...

Lunar Orbiter 2
The 1966 Lunar Orbiter 2 robotic spacecraft mission, part of the Lunar Orbiter Program, was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a cislunar trajectory and injected into an elliptical near-equatorial lunar orbit for data acquisition after 92.6 hours' flight time. The initial orbit was at an inclination of 11.8 degrees. The perilune was lowered to five days later after 33 orbits. A failure of the amplifier on the final day of readout, December 7, resulted in the loss of six photographs. On December 8, 1966 the inclination was altered to 17.5 degrees to provide new data on lunar gravity. The spacecraft acquired photographic data from November 18 to 25, 1966, and readout occurred through December 7, 1966. A total of ...

Sierpinski (crater)
Sierpinski is a lunar impact crater on the far side of the Moon. It lies to the southeast of the huge walled plain Gagarin, and to the northwest of the crater O'Day and the Mare Ingenii. This crater has undergone some wear, particularly along the southwest where Sierpinski Q intrudes slightly into the inner wall. The rim is higher and the inner wall wider along the eastern side. There is a prominent ridge within the interior that extends from near the midpoint to the northern inner wall. There are several small craters along the inner wall in the north and northwest. Only a small portion of the interior floor along the western half is relatively level. 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 Sierpinski.

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 ...

Mare Ingenii
Mare Ingenii (Latin ''ingeniī'', the "Sea of Cleverness") is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin, which is of the Pre-Nectarian epoch, which lies in turn in the outer part of the older and much larger South Pole–Aitken basin. The mare material located in Ingenii and the surrounding craters is of the Upper Imbrian epoch. The dark circular feature which dominates this mare is the crater Thomson (112 km diameter), with the overflow from Ingenii/Thomson directly to the east. Mare Ingenii is incompletely and thinly covered over much of its expanse with mare lava sheets. The light grey crater to the south of Mare Ingenii is Obruchev. The mare has swirling patterns of bright material, similar to Reiner Gamma and to patterns within Mare Marginis, which are not associated with topographic or volcanic features. The lunar swirls are believed to be associated with magnetic fields. Prior to formal naming in 1961 by the IA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gagarin (crater)
Gagarin is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. To the southwest is the crater Pavlov and to the northeast lies Keeler. Closer to the rim are the craters Levi-Civita to the southwest, and Beijerinck to the north-northeast. Isaev lies entirely within the northwest rim of Gagarin. In contrast with the floor of Gagarin, Isaev has a floor with a somewhat low albedo. Physical characteristics The crater is named for Yuri Gagarin, the cosmonaut who was the first human in space and the first to orbit the Earth. The six craters falling within the perimeter of Gagarin have also been named after pioneers of Russian aviation and astronautics, including Isaev, Grave, Balandin, Raspletin, Kosberg, and Andronov. Gagarin has been heavily eroded by a long history of crater impacts. The worn rim forms a low, circular ridge around the somewhat bowl-shaped interior. The inner floor is covered by a multitude of crater impacts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel Barbier
Daniel Barbier (10 December 1907 – 1 April 1965) was a French astronomer born in Lyon. Between 1930 and 1965 he published nearly 100 scientific papers on astronomy. Among his works were studies of stellar atmospheres and lunar occultations and eclipses. He performed studies of the upper atmosphere, Aurora Borealis, the zodiacal light and the night airglow. His name remains associated to the famous Eddington-Barbier relationships of analytical radiative transfer (see Barbier 1943 and Paletou 2018). Honors * The lunar crater '' Barbier'' was named after him in 1970. * Asteroid 37853 Danielbarbier, discovered by Eric Elst at La Silla Observatory in 1998, was named in his honor.

Cyrano (crater)
Cyrano is a lunar impact crater that lies on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It lies due east of the huge walled plain Gagarin, and to the north of the somewhat smaller crater Barbier. The most notable aspect of this crater are the small impacts along the western and southwest rim, with the pear-shaped Cyrano P forming the later intrusion into the interior. The remainder of the rim has received some wear, and is particularly eroded at the northern end. There are also a few small craters within the interior, with a merged crater pair near the eastern side and a crater along the northeast inner wall. The northern half of the interior floor is slightly more irregular than the southern part. Satellite craters By convention these features ...
