Berkner (crater)
Berkner is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It is attached to the east-southeast rim of the crater Parenago. Just to the south is the Robertson, and to the southeast is Helberg. The outer rim of this crater has been worn and eroded, particularly along the northwest half. The most intact part of the rim is to the southeast, while the remainder has been impacted and notched by smaller impacts, and to the southwest overlain by material. Prior to formal naming by the IAU The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and developmen ... in 1970, Berkner was called ''Crater 176''.

Lunar Orbiter 5
Lunar Orbiter 5, the last of the "Lunar Orbiter series", was designed to take additional Project Apollo, Apollo and Surveyor program, Surveyor landing site photography and to take broad survey images of unphotographed parts of the Moon's far side. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data and was used to evaluate the Manned Space Flight Network tracking stations and Apollo Orbit Determination Program. Mission summary The spacecraft was placed in a cislunar trajectory and on August 5, 1967 was injected into an elliptical near polar lunar orbit with an inclination of 85 degrees and a period of 8 hours 30 minutes. On August 7 the perilune was lowered to , and on August 9 the orbit was lowered to a , 3 hour 11 minute period. The spacecraft acquired photographic data from August 6 to 18, 1967, and readout occurred until August 27, 1967. A total of 633 high resolution and 211 medium resolution frames at resolution down to were ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Helberg (crater)
Helberg is a lunar impact crater that is located just behind the western limb of the Moon, on the far side from the Earth. Due to libration this part of the surface is sometimes brought into view, and the crater is visible under suitable lighting conditions. However even under these circumstances the crater is viewed from the edge and not much detail can be seen. This crater is nearly attached to the east-northeastern rim of the crater Robertson. Within a crater diameter to the northwest lies Berkner, and farther to the east is Bell. This is an eroded crater formation which overlies Helberg C along the east-northeastern side and Helberg H to the southeast. The southern rim is somewhat uneven, with an area of intrusion to the southwest. The interior floor has the remains of a crater rim at the northern end. It is otherwise relatively featureless. Prior to formal naming by the IAU The International Astronomical Union (IAU; , UAI) is an international non-governmental organiz ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people.

Robertson (crater)
Robertson is an important lunar impact crater that is located on the far side of the Moon, just beyond the western limb. It lies just to the south of Berkner, a formation with a comparable size but more eroded features. Just to the east is Helberg, and to the southwest is Alter. The inner wall of the crater rim has a wide, complex formation of multiple terraces. The rim is approximately circular, but with an irregular outline where various terraces have slumped away. The interior has a central peak at the midpoint, and this is joined to a rugged stretch of ground that connects with the northeastern rim. A band of light-hued ray material from Ohm covers the southern half of the crater floor and rim. Prior to formal naming by the IAU The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and developme ...

Lloyd Viel Berkner
Lloyd Viel Berkner (February 1, 1905 – June 4, 1967) was an American physicist and engineer. He was one of the inventors of the measuring device that since has become standard at ionospheric stations because it measures the height and electron density of the ionosphere. The data obtained in the worldwide net of such instruments were important for the developing theory of short wave radio propagation to which Berkner himself gave important contributions. Berkner was elected to the United States National Academy of Sciences in 1948. He was president of Associated Universities, Inc. from 1951 to 1960. Later he investigated the development of the Earth's atmosphere. Since he needed data from the whole world, he proposed the International Geophysical Year in 1950. At that time, the IGY was the largest cooperative study of the Earth ever undertaken. Berkner was elected a Fellow of the American Academy of Arts and Sciences and a member of the American Philosophical Society in 1956 ...

Parenago (crater)
Parenago is an impact crater on the Moon's far side, behind the eastern limb. Nearly attached to the east-southeastern outer rim of Parengo is the crater Berkner. To the south-southwest lies Comrie. This is a worn and eroded crater formation. Attached to the northern outer rim are the satellite craters Parenago W and Parenago Z. Three small craters lie prominently along the edge the inner wall in the southeast quadrant of the interior floor. The floor is otherwise relatively level and is marked by only a few tiny craterlets. Prior to formal naming by the IAU The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and developmen ... in 1970, Parenago was called ''Crater 173''.

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). Within the Solar System, it is the List of Solar System objects by ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
