Brisbane (lunar Crater)
Brisbane is a Lunar craters, lunar impact crater that is located in the southeastern part of the Moon, to the south of the crater Peirescius (crater), Peirescius. To the northwest lie the craters Vega (crater), Vega and Reimarus (crater), Reimarus, and farther to the east is the walled plain Lyot (lunar crater), Lyot. Due to its proximity to the limb, foreshortening of this crater causes it to appear somewhat elliptical in shape, even though it is actually circular. This is an old, eroded crater with features that have become somewhat softened and rounded due to a history of subsequent minor impacts. There are small craterlets along the rim, most notably along the western wall and the northeast inner wall. There is also a groove overlying the southwest rim. The interior floor is nearly level and contains no significant impacts. There is a slight central rise at the midpoint. Satellite craters By convention these features are identified on lunar maps by placing the letter on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing 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 polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...

Thomas Brisbane
Major General Sir Thomas Makdougall Brisbane, 1st Baronet, (23 July 1773 – 27 January 1860), was a British Army officer, administrator, and astronomer. Upon the recommendation of the Duke of Wellington, with whom he had served, he was appointed governor of New South Wales from 1821 to 1825. A keen astronomer, he built the colony's second observatory and encouraged scientific and agricultural training. Rivals besmirched his reputation and the British Secretary of State for the Colonies, Lord Bathurst, recalled Brisbane and his colonial secretary Frederick Goulburn. Brisbane, a new convict settlement, was named in his honour and is now the 3rd largest city in Australia. Early life Brisbane was born at Brisbane House in Noddsdale, near Largs in Ayrshire, Scotland, the son of Sir Thomas Brisbane and his wife Eleanora (née Bruce). He was educated in astronomy and mathematics at the University of Edinburgh. He joined the British Army's 38th (1st Staffordshire) Regiment of Foot ...

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 ...

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] |
Peirescius (crater)
Peirescius is a lunar impact crater that is located in the southeastern part of the Moon. It is close enough to the limb that it appears significantly foreshortened when viewed from the Earth, even though it is nearly circular in shape. To the west-northwest of Peirescius is the crater Vega, and less than one crater diameter to the south is Brisbane. Farther to the east is the Mare Australe. The outer parts of this crater has become eroded by smaller impacts, and several small craterlets lie along the rim or the inner wall. These have taken their toll upon the original crater shape, although it is nowhere near as badly eroded as the nearby Vega. The interior floor is a relatively featureless expanse, with only a low rise in the center and a small craterlet toward the northern rim. The crater was named in 1935 after Nicolas-Claude Fabri de Peiresc (1580–1637), the French astronomer, antiquary An antiquarian or antiquary () is an fan (person), aficionado or student of antiqui ...

Vega (crater)
Vega is an eroded lunar impact crater that is located in the southeastern part of the Moon. It lies on the near side and so can be viewed from the Earth. Less than one crater diameter to the east-southeast is the slightly smaller Peirescius. About one and a half crater diameters to the west is the long Vallis Rheita. This crater has been worn and eroded by a history of impacts. Vega B overlies the southern part of the southern floor and inner wall. The east-northeastern section of the rim is overlain by a merged pair of small craters. A cluster of small craters lies along the northwestern rim. The remainder of the outer rim is round-shouldered and marked by many tiny impacts. The southern part interior floor is partly overlaid by the outer rampart of Vega B. The remainder of the floor is relatively featureless except for a few tiny craters. This feature is named after the Slovenian mathematician Jurij Vega (Georg Freiherr von Vega in German German(s) may refer to: * Germany (o ...

Reimarus (crater)
Reimarus is a lunar impact crater, located in the southeastern part of the Moon's near side. The eroded southeastern end of the long Vallis Rheita (Rheita valley) passes just to the west. To the northeast is the larger and heavily worn crater Vega Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only from the Sun, an .... This is a heavily worn and eroded crater, with an outer rim that has been incised and battered by multiple lesser, later impacts, particularly in the western half. Several small craterlets lie along the rim edge and the inner walls, and the outer rise is generally uneven and rugged. On the southwest part of the interior floor is a small crater. The remainder of the floor is generally featureless and marked only by a few tiny craterlets. Satellite craters By convention these features are ...

Lyot (lunar Crater)
Lyot is a large lunar impact crater that is located along the southeastern limb of the Moon. It lies within the irregular and patchy lunar mare named Mare Australe, and to the south of the crater Hamilton. Due to its location, this formation is viewed at a low angle from the Earth, and its visibility is affected by libration. The interior floor of this crater has been resurfaced by lava, leaving a dark interior with an albedo that matches the surrounding mare. The outer rim is low and heavily worn, with a perimeter that forms a somewhat distorted circle. The southwest part of the floor and rim is marked by several small, bowl-shaped craters. There is also the remains of a ghost crater A palimpsest , in planetary astronomy, is an ancient crater that has been degraded over time. They may also be referred to as "ghost craters", "degraded craters", "buried craters", or "pathological craters". Palimpsests have been identified on ... to the east of the crater midpoint.

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 ...
