Poczobutt (crater)
Poczobutt is a large lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb in an area occasionally brought into sight due to libration effects. This is a damaged formation that is partly overlain by several named craters. Across the rim to the north-northeast is the crater Smoluchowski. The crater Zsigmondy overlies the northeastern rim, and Omar Khayyam is located in the western part of Poczobutt's interior. Little of the outer rim of this crater remains intact, and what survives is worn and eroded. The outer rim now forms an irregular ring of peaks, broken in several locations by small craters. The most intact portion of the rim is a small arc along the eastern side. Likewise much of the interior floor is irregular due to overlying impacts or their ejecta. However, there is a level plain in the eastern half of the interior that is almost flat and featureless. This region is marked only by a few low ridges around the fringes and some ...

Clementine (spacecraft)
''Clementine'' (officially called the Deep Space Program Science Experiment (DSPSE)) was a joint space project between the Ballistic Missile Defense Organization (previously the Strategic Defense Initiative Organization) and NASA, launched on January 25, 1994. Its objective was to test sensors and spacecraft components in long-term exposure to space and to make scientific observations of both the Moon and the near-Earth asteroid 1620 Geographos. Results Observation of the asteroid was not made due to a malfunction in the spacecraft. The lunar observations included imaging at various wavelengths in the visible as well as in ultraviolet and infrared, laser ranging altimetry, gravimetry, and charged particle measurements. These observations were for the purposes of obtaining multi-spectral imaging of the entire lunar surface, assessing the surface mineralogy of the Moon, obtaining altimetry from 60N to 60S latitude, and obtaining gravity data for the near side. There were als ... [...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 campaig ...

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.

Terrain
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, ...

Albedo
Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as obtained from flux measurements) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omar Khayyam (crater)
Omar Khayyam is a lunar impact crater that is located just beyond the northwestern limb of the Moon, on the far side from the Earth. It lies in a region of the surface that is sometimes brought into view of the Earth due to libration, and under favorable lighting it can be viewed from the edge. However under such circumstances not much detail can be seen, and the crater is best viewed from orbit. This feature is located at the western edge of the larger walled plain Poczobutt, and the northwestern rim of Omar Khayyam is overlain by the crater Zsigmondy. The east-southeastern part of the interior floor of Omar Khayyam is overlain by a smaller and younger crater. The remainder of the interior floor is split in half by a ridge attached to the western outer rim of this crater, giving Omar Khayyam the appearance of a formation composed of multiple merged impacts. The outer rim of Omar Khayyam is heavily eroded, and has a wide gap to the southeast. A small crater overlies the western ...

Marcin Odlanicki-Poczobutt
Marcin Odlanicki Poczobutt ( lt, Martynas Počobutas; 30 October 1728 near Grodno – 7 February 1810 in Daugavpils) was a Polish–Lithuanian Jesuit, astronomer and mathematician. He was professor of Vilnius University for over 50 years, serving as its rector from 1780 to 1799. The crater Poczobutt on the Moon is named after him. Career Marcin Odlanicki Poczobutt was born in the village of near Grodno, within Lithuania proper. He studied at Vilnius University (1745–1751) and Charles University in Prague (1754–1756). With brief interruptions he lectured at Vilnius University from 1753 to 1808. Sponsored by Michał Fryderyk Czartoryski, he further studied in France, Italy, and Germany from 1762 to 1764. His stay at the Marseille Observatory under inspired him to devote his career to astronomy. He earned doctorate of philosophy, gained professorship, and became director of the Vilnius Astronomical Observatory in 1764. The observatory, established by Thomas Zeb ...

Zsigmondy (crater)
Zsigmondy is a lunar impact crater located beyond the northwestern limb on the far side of the Moon. Attached to the southeastern rim of the crater is the crater Omar Khayyam, which lies within the much larger Poczobutt. Farther to the east, along the north rim of Poczobutt, is Smoluchowski. The rim of Zsigmondy is eroded and distorted in form, having a somewhat polygon In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed ''polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two toge ...al outline. It overlies a comparably sized crater formation Zsigmondy S along the western rim. A pair of small craters lies across the low western rim, and another pair is situated on the inner wall to the southeast. On the interior, the floor is relatively flat in the western half with a low central rise near the midpoint. Satellite craters By convention these ...
