Lyman (crater)
Lyman is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. It is located to the south of the huge walled plain Poincaré Poincaré is a French surname. Notable people with the surname include: * Henri Poincaré (1854–1912), French physicist, mathematician and philosopher of science * Henriette Poincaré (1858-1943), wife of Prime Minister Raymond Poincaré * Luci ..., and to the northeast of Schrödinger, another walled plain. To the east-southeast is the larger crater Minnaert. The rim of Lyman has not been significantly worn and has a well-defined edge and interior features that have not been eroded through impacts. The perimeter is roughly circular with outward bulges along the southern and eastern edges where slumping has occurred. Around much of the interior edge the unconsolidated material has collapsed, forming a ring-shaped pile around the edge of the interior floor. There are a few terraces along parts of the inner wall.

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] |
Minnaert (crater)
Minnaert is a large lunar impact crater that is located on the far side of the Moon, deep in the southern hemisphere. It is partly overlain along the southeastern side by the larger and younger crater Antoniadi. To the west-northwest lies Lyman Lyman may refer to: Places Ukraine * Lyman, Ukraine United States * Lyman, Iowa * Lyman, Maine * Lyman, Mississippi * Lyman, Nebraska * Lyman, New Hampshire * Lyman, Oklahoma * Lyman, South Carolina * Lyman, South Dakota * Lyman County, South Dak .... Nearly half the crater is overlain by the rim, outer rampart, and ejecta from Antoniadi. The remaining rim is worn and eroded, with a number of small craterlets along the edge and inner wall. The western interior floor is relatively level, but is marked by ejecta and secondary cratering from Antoniadi. If the crater ever possessed a central ridge, it may now be buried. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of th ... [...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 campaig ...

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.

Schrödinger (crater)
Schrödinger is a large lunar impact crater of the form traditionally called a walled plain and is named after Erwin Schrödinger. It is located near the south lunar pole on the far side of the Moon, and can only be viewed from orbit. The smaller crater Ganswindt is attached to the southwestern rim of Schrödinger, and intrudes slightly into the inner wall. Adjacent to the south is the crater Nefed'ev. Farther to the southwest is the crater Amundsen. Schrödinger is perhaps the moon's best example of a peak-ring basin. It possesses a wide outer rim that has been slightly rounded due to subsequent impacts. But the rim remains well-defined, and traces of terraces can be seen along the inner surface. The ejecta on the exterior forms an irregular outer rampart that extends for up to 100 kilometers. Within the interior is a second ring approximately half the diameter of the outer rim. This forms a circular range of rugged mountains that surrounds the center, with the exceptio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Lyman IV
Theodore Lyman IV (; November 23, 1874 – October 11, 1954) was a U.S. physicist and spectroscopist, born in Boston. He graduated from Harvard in 1897, from which he also received his Ph.D. in 1900. Career Lyman became an assistant professor in physics at Harvard, where he remained, becoming full professor in 1917, and where he was also director of the Jefferson Physical Laboratory (1908–17). He made important studies in phenomena connected with diffraction gratings, on the wavelengths of vacuum ultraviolet light discovered by Victor Schumann and also on the properties of light of extremely short wavelength, on all of which he contributed valuable papers to the literature of physics in the proceedings of scientific societies. Military service During World War I he served in France with the American Expeditionary Force, holding the rank of major of engineers.

Poincaré (crater)
Poincaré is a large lunar impact basin that lies in the southern hemisphere on the far side of the Moon. Most of the formation has been heavily eroded by subsequent impacts, leaving a battered formation with only rugged remnants of the original outer rim to the west. The eastern half has been completely worn away, and much of the interior has been resurfaced by lava flows. This surface has a lower albedo than the surrounding terrain, giving it a dark appearance. A rugged formation forms a low north–south range across the eastern section of the floor, possibly the remnant of an inner ring. The perimeter of Poincaré has several notable craters. To the north is the crater Hopmann, while the craters Abbe and Hess lie to the east. Directly to the west is Planck, a walled plain of similar dimensions to Poincaré. Both formations are sufficiently large to have formed a small lunar mare on the near side face of the Moon. The basin's name was adopted in 1970 by the IAU.

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
