Boguslawsky (crater)
Boguslawsky is a lunar impact crater that is located near the southern lunar limb, to the northwest of the slightly larger crater Demonax, and southwest of the concentric crater Boussingault. Due to its location, this crater appears very oblong in shape because of foreshortening. The floor of this crater is flooded and relatively featureless. The rim is somewhat worn and relatively low above the surrounding surface. The crater Boguslawsky D lies across the eastern rim. The crater was named after German astronomer Palm Heinrich Ludwig von Boguslawski. It has been proposed as the landing site for the Russian Luna 25 Luna 25 (Luna-Glob lander) is a planned lunar lander mission by Roscosmos. It will land near the lunar south pole at the Boguslavsky crater. It was renamed from Luna-Glob lander to Luna 25 to emphasize the continuity of the Soviet Luna progra ... lander.

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 ...

Palm Heinrich Ludwig Von Boguslawski
Palm (or Palon) Heinrich Ludwig (Pruß) von Boguslawski (7 September 1789 – 5 June 1851) was a German astronomy professor and observatory director in Breslau (Wrocław). Early life A native of Magdeburg, Boguslawski met Johann Elert Bode (1747–1826), who was an observatory director in Berlin and published the celestial atlas ''Uranographia'', at the Prussian Military Academy in Berlin between 1811 and 1812, when Boguslawski did his military service. Military service Boguslawski was an artillery officer in the Prussian Army during the French invasion of Russia (1812) led by Napoleon. He retired as ''Hauptmann''. Astronomy After the war, he took up residence on his family's lands outside Breslau. In 1831 he became curator at the observatory in Breslau, and was appointed in 1836 to an honorary professorship at the University of Breslau. In the night from 20 April to 21 April 1835, Boguslawski detected a comet, estimated its course, and reported it t''Herr Geheimer O ...

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] |
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 ...

Demonax (crater)
Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky. This crater has a worn and eroded rim, with several small craters lying along the edge and the inner walls. The southeast rim in particular has a notable collection of impacts, including the satellite crater Demonax A which intrudes into the interior floor. The crater bottom has been resurfaced, leaving a flat, level floor. However, there is a group of central peaks near the midpoint, and the northern part of the floor is rough and hummocky. The remains of some terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that borders and lies above the floodplain of a stream or river * Terra ...

Boussingault (crater)
Boussingault is a large lunar impact crater that lies near the rugged southeast limb 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 .... Because of its location, Boussingault appears highly oblong in shape due to foreshortening. To the southwest is the crater Boguslawsky, and almost attached to the northeast rim is Helmholtz. East-southeast of Boussingault lies the crater Neumayer. The most notable aspect of this crater is the large crater that lies entirely within its outer walls, so that it resembles a double-walled formation. The outer rim is worn and Boussingault K lies across the northwest rim. To the northwest is the overlapping triple crater formation of Boussingault E, B, and C. Satellite craters By convention these features are identified on lu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luna 25
Luna 25 (Luna-Glob lander) is a planned lunar lander mission by Roscosmos. It will land near the lunar south pole at the Boguslavsky crater. It was renamed from Luna-Glob lander to Luna 25 to emphasize the continuity of the Soviet Luna programme from the 1970s, though it is still part of what was at one point conceptualized as the Luna-Glob lunar exploration program. As of December 2022, the launch is scheduled for July 2023. History Nascent plans for what is now Luna 25 began in the late 1990s, with the evaluation of two spacecraft designs having taken place by 1998. Attempts to revive and complete the project continued throughout the 2000s and were punctuated by an aborted attempt at international cooperation via a merger with JAXA's now-cancelled Lunar-A orbiter, and pressure from another attempted cooperative lunar mission with Indian Space Research Organisation (ISRO) (which continued without Russia's involvement). Delays in the 2010s came first from the significant r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 ...
