Valier (crater)
Valier is a lunar impact crater that lies on the far side of the Moon. It is nearly attached to the western rim of the crater Tiselius. To the north-northwest lies the larger Sharonov, to the south-southwest is Coriolis Coriolis may refer to: * Gaspard-Gustave de Coriolis (1792–1843), French mathematician, mechanical engineer and scientist * Coriolis force, the apparent deflection of moving objects from a straight path when viewed from a rotating frame of referen ..., and west of Valier is Dufay. The most notable feature of this crater is the satellite crater Valier J that occupies the southeastern part of the interior floor and shares part of the outer rim. The remainder of the rim is somewhat worn, with small craters along the eastern side. The inner walls of Valier are uneven slopes that are marked by several tiny craters. The surviving interior floor is a relatively level surface with some tiny craters scattered about. Satellite craters By convention these features are ...

Apollo 16
Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's " J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to E ...

Coriolis (crater)
Coriolis is a lunar impact crater that is located on the far side of the Moon. The crater floor is bisected by the lunar equator, and it lies about three crater diameters northwest of the crater Daedalus. The rim of this formation is somewhat eroded, and several small craters lie along the edge. The northern rim is somewhat damaged, and has a slight outward bulge and depression in the side. The interior floor has small craters along the eastern and southern inner walls. There are also some low hills near the mid-part of 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 Coriolis. Satellite craters photographed by 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, an ...

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 ...

Dufay (crater)
Dufay is a lunar impact crater that is located on the far side of the Moon. It lies about one crater diameter to the east of the large walled plain Mandel'shtam. To the northwest is the crater Papaleksi and to the east is Valier. The rim of this crater is heavily worn by impacts, and several small craterlets lie along the southern edge. The inner wall is somewhat wider on the western side when compared to the east and southeast. The interior floor is relatively level and featureless. Albedo Anomaly To the northeast of Dufay is a bright albedo anomaly that does not correlate with any topographic features. The lunar surface at the anomaly is not atypical under low sun angles. The albedo anomaly is associated with an enhancement in Thorium.N. E. Petro.

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] |
Max Valier
Max Valier (9 February 1895 – 17 May 1930) was an Austrian rocketry pioneer. He was a leading figure in the world's first large-scale rocket program, Opel-RAK, and helped found the German ''Verein für Raumschiffahrt'' (VfR – "Spaceflight Society") that would bring together many of the minds that would later make spaceflight a reality in the 20th century. Biography Valier was born in Bozen in the County of Tyrol (now South Tyrol) and in 1913 enrolled to study physics at the University of Innsbruck. He also trained as a machinist at a nearby factory. His studies were interrupted by the First World War, during which he served in the Austro-Hungarian army's air corps as an aerial observer. After the war, Valier did not return to his studies, but became a freelance science writer. In 1923, he read Hermann Oberth's landmark book '' Die Rakete zu den Planetenräumen'' (''The Rocket into Interplanetary Space'') and was inspired to write a similar work to explain Oberth's ideas ...

Tiselius (crater)
Tiselius is a lunar impact crater that lies just to the east of Valier, on the Moon's far side. The craters Tiselius and Valier are separated by only a few kilometers. Less than one crater diameter to the east of Tiselius is the smaller, elongated Stein, and to the north is the small, eroded Šafařík. This is a roughly circular crater with a well-defined edge that has not been significantly degraded by impact erosion. The inner walls have slumped in places to form piles of scree. The interior floor is marked by a few small craterlets, and there is an irregular group of ridges around the midpoint. The small, cup-shaped satellite crater Tiselius E lies near the eastern outer edge. The crater was named after Swedish biochemist Arne Tiselius, by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical ...

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] |
