Anderson (crater)
Anderson is a lunar impact crater that is located on the far side of the Moon. It is located to the northwest of the crater Sharonov, and the satellite crater Sharanov X is attached to the southeast rim of Anderson. To the northeast is the peculiar formation Buys-Ballot, and to the east-southeast lies the larger crater Spencer Jones. The outer rim of Anderson is heavily worn and eroded. Small craters overlie the southeastern and southwestern rims. The interior is relatively flat, with multiple tiny craters covering parts of the floor. The most prominent of these is Anderson L, located near the southeastern rim. Anderson L is also commonly known as the Anderson Finger. The crater lies within the Freundlich-Sharonov Basin The Freundlich-Sharonov Basin is a Pre-Nectarian impact basin on the far side of the moon. It is named after the younger craters Freundlich near the northwest margin and Sharonov near the southwest margin. It lies east of Mare Moscoviense basi .... Sa ...

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] |
Buys-Ballot (crater)
Buys-Ballot is an oddly-shaped lunar impact crater that is located on the far side of the Moon. It lies just to the northwest of the small lunar mare named Lacus Luxuriae, and southeast of the crater Freundlich. Other nearby craters of note are Anderson to the southwest and Dante to the northeast. This formation has a distinctive shape for a crater, having a prominent extension to the south that nearly doubles the dimension compared to the width across the maximum west–east cross-section. It vaguely resembles a pear, with the thinner end to the south and the bulge to the north. Despite the odd shape, this crater has not been significantly eroded and only a few tiny craterlets mark the interior or the rim. Running down the middle of the crater along its longest dimension is a ridge that divides the southern part in half. This ridge extends as far north as the widest part before coming to an end. The floor at this widest part has been partially resurfaced by basaltic lava, le ... [...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 ...

Freundlich-Sharonov Basin
The Freundlich-Sharonov Basin is a Pre-Nectarian impact basin on the far side of the moon. It is named after the younger craters Freundlich near the northwest margin and Sharonov near the southwest margin. It lies east of Mare Moscoviense basin and northwest of Korolev basin. The basin is not obvious on lunar photographs, although it was discovered from analysis of Lunar Orbiter photographs. At the center is the small mare Lacus Luxuriae, just south of the oblique crater Buys-Ballot. Also at the center is a mass concentration (mascon), or gravitational high. The mascon was first identified by Doppler tracking of the Lunar Prospector spacecraft. Other craters within the basin include Anderson, Virtanen, Zernike, Dante, and the smaller Šafařík. Morse and Spencer Jones are at the margins.

Sharonov (lunar Crater)
Sharonov is a lunar impact crater that lies on the Moon's far side. It is located to the southeast of the crater Anderson, and to the southwest of the ray-covered Virtanen. To the south-southeast of Sharonov lies Valier. This crater is roughly circular, with a slight outward bulge along the southern rim. The rim edge is well-defined and has not been significantly degraded as a result of impact erosion. Sharonov partially overlays the smaller crater Sharonov X along the northwestern rim, which in turn connects to the southeastern outer rim of Anderson. The inner walls of Sharonov display some terraces, especially along the northern half. The interior is not marked by any significant impacts, but there are some ridges near the midpoint. Sharonov is probably part of the Eratosthenian System, but may be part of the Upper Imbrian System. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John August Anderson
John August Anderson (August 7, 1876 – December 2, 1959) was an American astronomer. He was born in Rollag, a small community in Clay County, Minnesota to the south of Hawley. Biography Anderson received his Ph.D. at Johns Hopkins University in 1907, and remained on the staff after graduation. In 1908, he became professor of astronomy at the university. In 1909, he was also given the responsibility for the Rowland ruling engines that were used for creating diffraction gratings, and the quality of these was considered excellent, especially the concave gratings. In 1916, he left to work at the Mt. Wilson observatory. He remained on the Mt. Wilson staff until 1956. His most notable contribution was his adaptation of the Michelson's interferometer technique for measuring close double stars. He used a rotating mask at the focus to measure the separation of Capella. In the 1920s, he collaborated with Harry O. Wood to develop a of seismograph. From 1928 until 1948, he was Executi ...

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 Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
