Lade (crater)
Lade is the remains of a lunar impact crater that has been flooded by lava. Its diameter is 58 km. It was named after German astronomer Heinrich Eduard von Lade. To the north is the crater Godin and to the south-southwest is the worn, lava-flooded Saunder. The southern rim of Lade has been completely covered or destroyed, and there are gaps in the relatively thin southeast rim. The surviving crater wall is worn and somewhat hexagon In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon.

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 ...

Hexagon
In geometry, a hexagon (from Ancient Greek, Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple polygon, simple (non-self-intersecting) hexagon is 720°. Regular hexagon A ''regular polygon, regular hexagon'' has Schläfli symbol and can also be constructed as a Truncation (geometry), truncated equilateral triangle, t, which alternates two types of edges. A regular hexagon is defined as a hexagon that is both equilateral polygon, equilateral and equiangular polygon, equiangular. It is bicentric polygon, bicentric, meaning that it is both cyclic polygon, cyclic (has a circumscribed circle) and tangential polygon, tangential (has an inscribed circle). The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals \tfrac times the apothem (radius of the inscribed figure, inscribed circle). All internal angles are 120 degree (angle), degrees. A regular hexago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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 ...

Saunder (crater)
Saunder is a lunar impact crater located in the central highland region of the Moon, to the east-northeast of the walled plain Hipparchus. Its diameter is 44 km. It was named after British mathematician Samuel Arthur Saunder Samuel Arthur Saunder (1852 – December 8, 1912) was a British mathematician and selenographer who taught at Wellington College, Berkshire. In 1894 he became a fellow of the Royal Astronomical Society, and in 1908 he was made Gresham Professor o .... The outer wall is irregular and broken in several locations, forming the overall shape of a pentagon. The interior of Saunder has been flooded with lava, forming a level surface just below the rim. The floor lacks a central peak, but there are low rises in the southeast quadrant and a tiny craterlet towards the north rim. 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 Saunder. References * * * ...

Heinrich Eduard Von Lade
Heinrich Eduard von Lade (24 February 1817 – 7 August 1904) was a German banker and amateur astronomer. He was born in Geisenheim, located along the banks of the Rhine river, the son of a wine merchant. He worked as a banker and exporter in Hamburg and Paris, and by the age of 44 he had earned enough to retire. In 1861 he built a private estate Monrepos in Geisenheim. There he dedicated himself to culturing fruit and wine, and established a school at the site to teach the art. He also built an observatory on the estate to pursue his interest in selenography, or mapping the Moon. He commissioned the construction of a lunar globe with one side in physical relief and the other with hashed relief and the crater names. This globe is now a very rare collector's item. In 1901 he was elevated to nobility and became a baron. He died in Geisenheim, which is still famous for its wine and the Geisenheim Grape Breeding Institute. Honors The crater Lade on the Moon is named after him, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Godin (crater)
Godin is a lunar impact crater located just to the south of the crater Agrippa, on a rough upland region to the east of Sinus Medii. Its diameter is 34 km. The crater was named after 18th century French astronomer Louis Godin. The ruined crater Tempel lies to the northeast, on the east side of Agrippa. Due south is the flooded remains of Lade. The rim of Godin is wider in the southern half than in the north, giving it a slightly pear-shaped outline. The interior is rough-surfaced, with a higher albedo than the surroundings. At the midpoint a central peak rises from the floor. A faint ray system surrounds the crater, and extends for about 375 kilometers. Due to its rays, Godin is mapped as part of the Copernican System.The geologic history of the Moon, 1987, Wilhelms, Don E.; with sections by McCauley, John F.; Trask, Newell J.

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
