Freundlich (crater)
Freundlich is a lunar impact crater that is located on the far side of the Moon. It lies midway between the craters Trumpler to the north-northwest and the irregular Buys-Ballot to the south-southeast. This crater has a circular rim that is more heavily eroded at the northern and southern ends. Groups of craters lie across the floor to the southeast and the north, and individual small craters lie elsewhere within the interior. The crater is named after Erwin Freundlich. 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 bas ....

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] |
Erwin Freundlich
Erwin Finlay-Freundlich FRSE FRAS (; 29 May 1885 – 24 July 1964) was a German astronomer, a pupil of Felix Klein. Freundlich was a working associate of Albert Einstein and introduced experiments for which the general theory of relativity could be tested by astronomical observations based on the gravitational redshift. Life He was born in Biebrich, Germany the son of Friedrich Philipp Ernst Freundlich, a manufacturer, and his wife Elizabeth (Ellie) Finlayson. He was one of seven children, all of whom were raised Protestant, despite their father's Jewish heritage. His elder brother was Herbert Max Finlay Freundlich. He studied locally, leaving school in 1903. He spent 6 months working in the shipyards of Stettin which inspired him to begin studying shipbuilding at the Charlottenburg Polytechnic in Berlin. However he abandoned this in autumn 1905 to instead study Mathematics and Astronomy at Göttingen. Here he studied under Felix Klein and Karl Schwarzschild. In 1913 he m ...

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.

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] |

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] |
