Henyey (crater)
Henyey is a lunar impact crater that lies on the far side of the Moon from the Earth. It is attached at the southern end to the northern rim of the crater Dirichlet. Less than a crater diameter to the northeast is the large crater Mach, and to the northwest lies Mitra ''Mitra'' ( Proto-Indo-Iranian: ''*mitrás'') is the name of an Indo-Iranian divinity from which the names and some characteristics of Rigvedic Mitrá and Avestan Mithra derive. The names (and occasionally also some characteristics) of these t .... This is a worn and eroded crater that has been partly disintegrated by subsequent impacts. The elongated crater Henyey U is attached to the western outer rim. The western interior floor of Henyey is disrupted by some small craters. Henyey lies on the eastern margin of the Dirichlet-Jackson Basin. 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 Henyey. See ...

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitra (crater)
Mitra is a lunar impact crater that is attached to the western outer rim of the larger crater Mach, on the far side of the Moon. Just to the west of Mitra is Bredikhin, and to the south-southeast lies Henyey. It is named after Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan award recipient known for his pioneering work in the field of ionosphere and radiophysics. This is a heavily eroded formation with an outer rim that has been damaged by subsequent impacts. Attached to the exterior along the southeast is the satellite crater Mitra J. A number of smaller impacts lie along the rim edge, and very little of the original rim remains intact. Within the interior, a smaller crater occupies the southwestern part of the floor, and a small, cup-shaped crater lies across the northeast rim of this formation and very close to the midpoint of Mitra. The remaining floor is marked only by a few small and tiny craterlets. Mitra lies within the Dirichlet–Jackson Basin. Sate ...

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 ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

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 ...

Mach (crater)
Mach is a large lunar impact crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest. This is a prominent but eroded formation with multiple craters along the rim and interior. The crater Harvey breaks across the eastern rim, and its outer rampart spills across the interior floor of Mach. The overall shape of Mach resembles a pear, with a prominent outward bulge to the northeast. Such a bulge can be caused by a second, merged crater. The northern edge is also the most worn and overlain by impacts. The interior of Mach is marked by several small craters, particularly in the northeastern bulge. Several craters also lie along the edges to the west and northwest. The remainder of the interior floor is relatively level, when compared to the terrain that surrounds Mach. There is a forma ...

Kilometre
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre ...

Dirichlet (crater)
Dirichlet is a lunar impact crater that is located on the Moon's far side. It is attached to the southern outer rim of the crater Henyey. To the south-southeast is the much larger crater Tsander. This is a circular crater with a sharp-edged rim that is not significantly worn. There are slight outward protrusions along the eastern side. The sides of the inner walls have slumped down to form a ring of scree Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically ha ... along the base. Dirichlet lies on the eastern margin of the Dirichlet-Jackson Basin.
