Berlage (crater)
Berlage is an old lunar impact crater that lies in the southern hemisphere on the far side of the 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 .... The smaller crater Bellinsgauzen is attached to its northern rim, and Cabannes is less than one crater diameter to the northwest. To the east-northeast of Berlage is Lemaître. This formation is unusual for the high density of small impact craters that lie across the interior and along the rim, especially in the northern half. The crater is heavily eroded, and the original features have been worn down with the passage of time. A combination of three small craters lie across the northern rim, at the eastern edge of the rim where Berlage is joined to Bellinsgauzen. Satellite craters By convention these features are identified on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hendrik Petrus Berlage (astronomer)
Hendrik Petrus Berlage (21 February 1856 – 12 August 1934) was a Dutch architect. He is considered one of the fathers of the architecture of the Amsterdam School. Life and work Hendrik Petrus Berlage, son of Nicolaas Willem Berlage and Anna Catharina Bosscha, was born on 21 February 1856 in Amsterdam in the Netherlands. Anna Catharina Bosscha's uncle was Johannes Bosscha, a scientist who taught in Polytechnische School te Delft. Berlage studied architecture at the Zurich Institute of Technology between 1875 and 1878 after which he traveled extensively for 3 years through Europe. In the 1880s he formed a partnership in the Netherlands with Theodore Sanders which produced a mixture of practical and utopian projects. A published author, Berlage held memberships in various architectural societies including CIAM I. Berlage was influenced by the Neo-Romanesque brickwork architecture of Henry Hobson Richardson and of the combination of structures of iron seen with brick of th ...

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Sphere
A sphere () is a Geometry, geometrical object that is a solid geometry, three-dimensional analogue to a two-dimensional circle. A sphere is the Locus (mathematics), set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre (geometry), centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the Greek mathematics, ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubble (physics), Bubbles such as soap bubbles take a spherical shape in equilibrium. spherical Earth, The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres rolling, roll smoothly in any direction, so mos ...

Far Side (Moon)
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Soviet Luna 3 space probe. The Soviet Academy of Sciences published the ...

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] |
Bellinsgauzen (crater)
Bellinsgauzen is a lunar impact crater that lies in the southern part of Moon, on the far side from the Earth. It is attached to the northern rim of the larger crater Berlage Hendrik Petrus Berlage (21 February 1856 – 12 August 1934) was a Dutch architect. He is considered one of the fathers of the architecture of the Amsterdam School.

Cabannes (crater)
Cabannes is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The rim has been worn by subsequent impacts, with a smaller crater overlying the southern rim. However the formation has not been significantly reshaped by nearby craters. The satellite crater Cabannes J is attached to the southeast rim, and lies between Cabannes and the heavily impacted crater Berlage Hendrik Petrus Berlage (21 February 1856 – 12 August 1934) was a Dutch architect. He is considered one of the fathers of the architecture of the Amsterdam School. Life and work Hendrik Petrus Berlage, son of Nicolaas Willem Berlage and A ....

Lemaître (crater)
Lemaître is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the south of the older crater Minkowski, and north of Crommelin. To the east-southeast lies the crater Eijkman. The outer rim of Lemaître remains well-defined, although it has become eroded and rounded by a history of minor impacts. The rim is generally circular, but it has a polygonal, angular outline, particularly in the southeastern half. For much of circumference, the inner wall consists of a rim that slopes down to a slumped terrace, which then slopes down more gently to the interior floor. There are a few tiny craterlets lying along the rim of Lemaître, especially in the west and the southeast. The most notable of these craterlets is a small, bowl-shaped crater that is attached to the southwestern rim. The floor of the crater is generally flat, but contains a prominent crater Lemaître F along the eastern inner wall. This crater is also somewhat angula ...
