Pannekoek (crater)
Pannekoek is a lunar impact crater that is situated on the far side of the Moon, and cannot be seen directly from the Earth. The crater lies along the northern edge of the slightly larger Dellinger, and their common border forms an area of uneven terrain. Due north of Pannekoek is the huge walled plain Mendeleev. The crater is named after astronomer and father of Council Communism, Antonie Pannekoek. This is a worn and eroded crater, although the perimeter of the rim is still visible. The southern part of the interior floor is jumbled and irregular. There is a small crater next to the inner wall along the west-southwest part of the floor. A smaller crater also lies in the interior along the northeast inner wall. There are also several small craterlets on the floor. 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 Pannekoek. Pannekoek S is similar to a few other far-side cra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonie Pannekoek
Antonie “Anton” Pannekoek (; 2 January 1873 – 28 April 1960) was a Dutch astronomer, philosopher, Marxist theory, Marxist theorist, and socialist revolutionary. He was one of the main theorists of council communism (Dutch: ''radencommunisme''). Biography Pannekoek studied mathematics and physics in Leiden from 1891. Even before he went to college he was interested in astronomy and studied the Milky Way and variability of Polaris. He published his first article, ''On the Necessity of Further Researches on the Milky Way'', as a student. He briefly worked as a geodesist before he returned to the Leiden Observatory (''Leidse Sterrewacht'') to work as an observer and write his thesis on the variability of Algol. After reading Edward Bellamy's ''Equality (novel), Equality'', Pannekoek became a convinced socialism, socialist and started studying the philosophies of Karl Marx and Joseph Dietzgen. Soon Pannekoek became a well-known Marxist writer, writing for both Dutch and Germa ... [...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 ...

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] |
Apollo 11
Apollo 11 (July 16–24, 1969) was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module ''Eagle'' on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin ''Columbia''. Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and it was the fifth crewed mission of NASA's Apollo program.

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 ...

Council Communism
Council communism is a current of communist thought that emerged in the 1920s. Inspired by the November Revolution, council communism was opposed to state socialism and advocated workers' councils and council democracy. Strong in Germany and the Netherlands during the 1920s, council communism continues to exist as a small minority in the left. History Emergence Council communism emerged in the years after 1918, as some communists in Germany and the Netherlands concluded that the Russian Revolution had led to power being concentrated in the hands of a new political elite. Its most prominent early proponents were the German educator Otto Rühle, the Dutch astronomer Anton Pannekoek, and the Dutch poet Herman Gorter. They were initially enthusiastic supporters of the Bolsheviks and the Russian Revolution. In 1918, Gorter said that the Bolshevik leader Vladimir Lenin "stands out above all other leaders of the Proletariat" and that Karl Marx was Lenin's sole peer. In 1919, Pa ...
