Lunar Orbiter 2
The 1966 Lunar Orbiter 2 robotic spacecraft mission, part of the Lunar Orbiter Program, was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a cislunar trajectory and injected into an elliptical near-equatorial lunar orbit for data acquisition after 92.6 hours' flight time. The initial orbit was at an inclination of 11.8 degrees. The perilune was lowered to five days later after 33 orbits. A failure of the amplifier on the final day of readout, December 7, resulted in the loss of six photographs. On December 8, 1966 the inclination was altered to 17.5 degrees to provide new data on lunar gravity. The spacecraft acquired photographic data from November 18 to 25, 1966, and readout occurred through December 7, 1966. A total of 60 ...

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 ...

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 Å afaÅ™Ãk. 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 terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that borders and lies above the floodplain of a stream or river * Terrace, a street suffix * Terrace, the portion of a lot between the public sidewalk an ...s, especially along the northern half.

VojtÄ›ch Å afaÅ™Ãk
VojtÄ›ch Å afaÅ™Ãk (26 October 1829 in Újvidék, Bács-Bodrog County, Vojvodina, Hungary (today Serbia) – 2 July 1902 in Prague, Bohemia) was a Czech chemist, specialising in inorganic chemistry. Å afaÅ™Ãk was the son of Pavel Jozef Å afárik, a Slovak philologist and historian. The crater Å afaÅ™Ãk on the Moon is named after him, and so is the minor planet 8336 Å afaÅ™Ãk (in conjunction with his wife). Work In Göttingen, he was involved in the investigation of the reaction of metals with alkyl iodides and produced diethylmagnesium. He also worked on the chemical composition of platinum and vanadium catalysts, and on organometallic compounds ( Grignard compounds). At the Vienna Academy he published a work on physical chemistry. He also studied mineralogy. In 1859, together with fellow chemist AntonÃn BÄ›lohoubek, he participated in a detailed chemical and microscopic analysis of the authenticity of the notorious Queen's Court (Dvůr Králové) and Green Mountain ...

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 Å afaÅ™Ãk. 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 r ...

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] |
