Kirchhoff (crater)
Kirchhoff is a small lunar impact crater that is located in the northern part of the Montes Taurus range. It was named after German physicist Gustav Kirchhoff. It lies to the west of the crater Newcomb, and southeast of the crater pair of Hall In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age and early Middle Ages in northern Europe, a mead hall was where a lord and his retainers ate and also slept. Later in the Middle Ages, the gr ... and G. Bond. This is a circular, bowl-shaped feature that lies in the midst of rugged lunar terrain. The satellite crater Kirchhoff C adjoins the eastern rim. There is a low rise at the midpoint of the interior floor.

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 ...

Gustav Kirchhoff
Gustav Robert Kirchhoff (; 12 March 1824 – 17 October 1887) was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. He coined the term black-body radiation in 1862. Several different sets of concepts are named "Kirchhoff's laws" after him, concerning such diverse subjects as black-body radiation and spectroscopy, electrical circuits, and thermochemistry. The Bunsen–Kirchhoff Award for spectroscopy is named after him and his colleague, Robert Bunsen. Life and work Gustav Kirchhoff was born on 12 March 1824 in Königsberg, Prussia, the son of Friedrich Kirchhoff, a lawyer, and Johanna Henriette Wittke. His family were Lutherans in the Evangelical Church of Prussia. He graduated from the Albertus University of Königsberg in 1847 where he attended the mathematico-physical seminar directed by Carl Gustav Jacob Jacobi, Franz Ernst Neumann and Friedrich Julius Ri ...

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 ...

Montes Taurus
Montes Taurus is a rugged, jumbled mountainous region on the Moon. It is located to the east of the Mare Serenitatis, in the northeastern quadrant of the Moon's near side. Coordinates of their center are , and their extent is about 170 km. Montes Taurus are rather unimpressive and indistinct compared to other named lunar mountain systems. It is a broad hilly region without sharp borders. These mountains reach maximal height between craters Kirchhoff and Newcomb (4.9 km above Mare Serenitatis and 2.1 km above mean level of lunar surface). A number of craters lie embedded within this range. At the southwestern edge of the region is the crater Römer, and Newcomb is located in the northeastern section. Several satellite craters also lie throughout the Montes Taurus. Southwestern edge of this region hosts Taurus–Littrow valley, the landing site of the manned Apollo 17 mission. Name The Montes Taurus are named after Taurus Mountains in southern Turkey. This name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newcomb (lunar Crater)
Newcomb is a lunar impact crater that is located in the rugged Montes Taurus mountain range, to the east of the Mare Serenitatis. It lies to the northeast of the prominent crater Römer, and north-northwest of Macrobius. This crater has a sharp-edged and somewhat irregular rim that appears polygonal more than circular. There are terraces along the inner sides, with some slumping along the northern and western inner edge. The south-southwestern part of the rim is overlaid by the smaller crater Newcomb A. The interior floor is uneven, particularly near the rim of Newcomb A. Just to the south-southeast of the crater is the satellite crater Newcomb J. This feature is named after the American astronomer Simon Newcomb. 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 Newcomb.

Hall (lunar Crater)
Hall is a lunar impact crater in the southeast part of the Lacus Somniorum, a lunar mare in the northeast part of the Moon. It was named after American astronomer Asaph Hall. This feature can be found to the east of the prominent walled plain Posidonius. Just to the south, and nearly attached to the southern rim of Hall is the smaller crater G. Bond. This crater formation has been significantly disintegrated by smaller impacts around the outer rim, leaving a wall that is deeply notched and incised. There is a gap in the western rim through which the interior has been flooded and resurfaced by layers of basaltic lava. Thus all that remains of the original crater is an irregular, crescent-shaped formation along the southern edge of the Lacus Somniorum. The southern rim is attached to the rough terrain to the south of the mare, and the irregular satellite crater G. Bond G is attached to the southeast rim. Passing across the open mouth of this crater is the rille Rille (G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
