Very (lunar Crater)
Very is a small lunar impact crater located in the eastern part of Mare Serenitatis, to the west-southwest of Le Monnier. It lies upon a wrinkle ridge that runs to the north and south named Dorsa Smirnov. It was named after American astronomer Frank W. Very. The crater was previously known as Le Monnier B, a satellite crater of Le Monnier, before being renamed by the IAU in 1973.

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 ...

Topographic Map
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system. Natural Resources Canada provides this description of topographic maps: Other authors define topographic maps by contrasting them with ...

Kalmbach Books
Kalmbach Media (formerly Kalmbach Publishing Co.) was an American publisher of books and magazines, many of them railroad-related, located in Waukesha, Wisconsin. History The company's first publication was ''The Model Railroader'', which began publication in the summer of 1933 at 545 S. 84th Street in Milwaukee (now site of a car wash), with a cover date of January 1934. A press release announcing the magazine appeared in August 1933, but did not receive much interest. In 1940, business was good enough for Kalmbach to launch another magazine about railroads in general with the simple title of '' Trains Magazine''. From its first issue dated November 1940, it grew quickly from an initial circulation of just over 5,000. Kalmbach became exclusively a publisher when it discontinued its printing operations in 1973, opting to contract production from other printers, that spot (on the 3rd floor) would later be home to the ''Milwaukee Racine & Troy'' model railroad, which would be ...

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 it was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities, spacecraft developments, and newly released space-related data. McDowell's report occasionally corrects NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States ...'s official web sites, or provides additional data on classified launches that are not available elsewhere ...

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium 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. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. 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 ...

Wrinkle Ridge
A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created after the lava cooled and solidified. They frequently outline ring structures buried within the mare, follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called ''veins'' due to their resemblance to the veins that protrude from beneath the skin. Wrinkle ridges are named with the Latin designation ''dorsum'' (plural ''dorsa''). The standard IAU nomenclature uses the names of people (generally scientists) to identify wrinkle ridges on the Moon. For example, the Dorsa Burnet are named for Thomas Burnet, and the Dorsum Owen is named after George Owen of Henllys. Wrinkle ridges can also be found on Mars, for example in Chryse Planitia, on several of the asteroids that have been visited ...

Frank Washington Very
Frank Washington Very (February 12, 1852 – November 23, 1927) was a U.S. astronomer, astrophysicist, and meteorologist. He was born in Salem, Massachusetts, and educated at Massachusetts Institute of Technology (1873) where he taught physics after his graduation. After several years at MIT, Very was employed at the Allegheny Observatory at the University of Pittsburgh, where he worked from 1878–1895. In 1890, he became a professor and chair of astronomy at the University of Pittsburgh (then known as the Western University of Pennsylvania), concurrent with his post at Allegheny Observatory. He was then made professor and acting director of the Ladd Observatory at Brown University from 1896–1897. After his time at Brown, he worked as an independent researcher for nearly a decade until 1906, when he was appointed director of the Westwood Astrophysical Observatory in Westwood, Massachusetts. Very's most important work was in measuring the temperatures of the surfaces of t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Le Monnier (crater)
Le Monnier is the remnant of a Lunar craters, lunar impact crater that has been partly inundated by lava flows. It was named after French astronomer Pierre Charles Le Monnier. It is located on the eastern edge of Mare Serenitatis, and the western part of the rim is missing so that it now forms a large bay. To the north is the crater Chacornac (crater), Chacornac. The interior of this formation is relatively flat and smooth, with no significant craterlets to mark the surface. The outer rim is battered, worn, and notched with past impacts. Only slight wrinkle ridges now mark where the western rim once lay. The landing site of the Luna 21 space probe is located near the southern rim of Le Monnier. Lunokhod 2, a robotic roving vehicle deposited on the surface by Luna 21, covered a distance of 37 kilometers across the crater floor. It also surveyed the southern edge of the crater rim. Satellite craters By convention these features are identified on lunar maps by placing the letter o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
