Tannerus (crater)
Tannerus is a small lunar impact crater that is located in the rugged southern highlands of the Moon. It lies within a couple of crater diameters of Asclepi to the northeast, and some distance due east of Jacobi Jacobi may refer to: * People with the surname Jacobi (surname), Jacobi Mathematics: * Jacobi sum, a type of character sum * Jacobi method, a method for determining the solutions of a diagonally dominant system of linear equations * Jacobi eigenva .... The rim of this crater is very close to circular, with only a slight inward bulge along the north edge where it is joined to Tannerus P. The edge is sharp and well-defined, although there are tiny impacts along the rim in the west and south. The crater floor is level and free of markings or features of note. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tannerus.

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 ...

Adam Tanner (mathematician)
Adam Tanner (in Latin, Tannerus; April 14, 1572 – May 25, 1632) was an Austrian Jesuit theologian. He was born in Innsbruck, Austria. In 1589 he joined the Society of Jesus and became a teacher. By 1603 he was invited to join the Jesuit College of Ingolstadt and take the chair of theology at the University of Ingolstadt. Fifteen years later he was given a position at the University of Vienna by the Emperor Matthias. He was noted for his defense of the Catholic church and their practices against Lutheran reformers as well as the Utraquists. His greatest work was the ''Universa theologia scholastica'', published in 1626–1627. He died at the village of Unken near Salzburg, and rests in an unmarked grave. Apparently the parishioners refused to give him a Christian burial because a "hairy little imp" was found on a glass plate among his possessions.

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] |
Asclepi (crater)
Asclepi is a heavily eroded lunar impact crater that lies in the rugged southern highlands 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 outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result, the crater is now little more than a depression in the surface. The interior is nearly flat and relatively featureless. The rim of Asclepi is marked only by a small crater across the western rim, and several tiny craterlets. The satellite crater Hommel K is a more recent impact that is attached to the southeast rim. This is a bowl-shaped formation with a sharp edge and a small central floor. Nearby craters of note include Pitiscus to the north-northeast, Hommel ...

Jacobi (crater)
Jacobi is a lunar impact crater that is located in the southern highlands on the near side of the Moon. It lies southeast of the crater Lilius, with Cuvier to the north-northwest and Baco to the northeast. The crater is 68 kilometers in diameter and 3.3 kilometers in depth. It is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. This crater has a worn rim that is overlain by several craters along the southern face, including Jacobi J, and a pair on the northern rim. The result is an outer rim that appears flattened along the northern and southern faces. The larger of the craters on the north rim, Jacobi O, forms a member of a chain of craters that form a rough line across the interior floor from northeast to southwest. The central part of this chain in particular forms a merger of several tiny craters at the midpoint of the floor. The remainder of the floor is level, perhaps as a result of erosion or ...

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 campaigne ...
