Biela (crater)
Biela is a lunar impact crater that is located in the rugged highlands of the southeastern Moon. It is named after Austrian astronomer Wilhelm von Biela. The crater lies to the east of Rosenberger, to the southeast of the Watt–Steinheil double crater. The rim of this crater is overlaid by a pair of small but notable craters: Biela C across the northeast rim and Biela W along the western inner wall. The satellite crater Biela B is attached to the southwestern outer rim, and ejecta Ejecta (from the Latin: "things thrown out", singular ejectum) are particles ejected from an area. In volcanology, in particular, the term refers to particles including pyroclastic materials (tephra) that came out of a volcanic explosion and magma ... from Biela covers the northwestern part of the interior. Despite a certain degree of wear, the rim of Biela remains relatively well-defined, especially in the southeast. The interior floor is flat and not marked by any craterlets of note.

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 ...

Wilhelm Von Biela
Baron Wilhelm von Biela (german: Wilhelm Freiherr von Biela; March 19, 1782 – February 18, 1856) was a German-Austrian military officer and amateur astronomer. Wilhelm von Biela was born in Roßla, Harz (Northern Germany). He was a descendant of a prominent Protestant noble family originally from what is now the Czech Republic, the family having been exiled to Saxony after its head, Friedrich von Biela, was executed in Prague in 1621 during the religious wars of the period.Solc, M.History of the comet 3D/Biela in ''Electronic supplement to Dissertatio cum Nuncio Sidereo'', Series Tertia, No. 7 – 22 August 2006 Biela was the last member of his branch of the family.von Wurzbach, C.

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] |
Rosenberger (crater)
Rosenberger is an old lunar impact crater in the southeastern part of the Moon. It was named after German astronomer Otto August Rosenberger. This crater is located in a region rich with prominent craters. The slightly smaller Vlacq is nearly attached to the northwestern outer rim of Rosenberger. Other nearby craters of note include Biela Biela may refer to: * Biela, Bohemia, former name of a town in eastern Bohemia, now Luže *Biela, Greater Poland Voivodeship (west-central Poland) *Biela (river), a river in eastern Germany. *Wilhelm Freiherr von Biela, an Austrian military office ... to the east, Hagecius to the south-southeast, and Nearch to the south-southwest. Due west past Vlacq is Hommel. This crater has been heavily eroded by a history of impacts, so that the outer rim has become rounded and somewhat indistinct. As a result, the crater possesses only a shallow rise along the rim edge, and it nearly forms a circular depression in the surface. The satellite crater Ros ...

Watt (crater)
Watt is a lunar impact crater that is located in the southeastern part of the Moon. It was named after Scottish inventor James Watt. The northwestern third of the crater rim has been completely overlain by the same-sized Steinheil, leaving much of the interior floor covered with the outer rampart of ejecta from the latter formation. The remainder of the rim of Watt is somewhat jagged in appearance, with an inward bulge along the southeast rim and a pair of small outward projections to the northeast. The rim is otherwise relatively sharply defined, with only a minor amount of wear. Nearby craters of note include Biela Biela may refer to: * Biela, Bohemia, former name of a town in eastern Bohemia, now Luže * Biela, Greater Poland Voivodeship (west-central Poland) *Biela (river), a river in eastern Germany. * Wilhelm Freiherr von Biela, an Austrian military offi ... to the south-southeast, Rosenberger to the southwest, and the walled plain Janssen to the northwest past Steinhei ...

Steinheil (crater)
Steinheil is a lunar impact crater that is located in the rugged highlands in the southeastern part of the Moon. It was named after German astronomer and physicist Carl August von Steinheil. It forms a prominent crater pair with the similar-sized Watt, which it partly overlies to the southeast. To the northwest is the large walled plain Janssen. Due to the location of this crater, it appears foreshortened when viewed from the Earth. It is from the Nectarian The Nectarian Period of the lunar geologic timescale runs from 3920 million years ago to 3850 million years ago. It is the period during which the Nectaris Basin and other major basins were formed by large impact events.

Ejecta
Ejecta (from the Latin: "things thrown out", singular ejectum) are particles ejected from an area. In volcanology, in particular, the term refers to particles including pyroclastic materials (tephra) that came out of a volcanic explosion and magma eruption volcanic vent, or crater, has traveled through the air or under water, and fell back on the ground surface or on the ocean floor. Volcanology Typically in volcanology, ejecta is a result of explosive eruptions. In an explosive eruption, large amounts of gas are dissolved in extremely viscous lava; this lava froths to the surface until the material is expelled rapidly due to the trapped pressure. Sometimes in such an event a lava plug or volcanic neck forms from lava that solidifies inside a volcano's vent, causing heat and pressure to build up to an extreme with no way to escape. When the blockage breaks and cannot sustain itself any longer, a more violent eruption occurs, which allows materials to be ejected out of the volc ...
