Lunar Orbiter 2
The 1966 Lunar Orbiter 2 robotic spacecraft mission, part of the Lunar Orbiter program, 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 program, Surveyor and Project Apollo, Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission summary The spacecraft was placed in a Free-return trajectory, 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 Nove ...

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 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] |

Tiselius (crater)
Tiselius is a Lunar craters, lunar impact crater that lies just to the east of Valier (crater), Valier, on the Moon's Far side (Moon), 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 (lunar crater), Stein, and to the north is the small, eroded Å afaÅ™Ãk (crater), 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 Wilhelm Kaurin Tiselius, Arne Tiselius, by the International Astronomical Union, IAU in 1979.

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States).
