Wright (lunar Crater)
Wright is a lunar impact crater that is located near the western limb of the Moon. It lies on the irregular plain between the Montes Cordillera and Montes Rook, two ring-shaped mountain ranges that surround the Mare Orientale. Just to the southeast of the crater is the slightly larger crater Shaler. To the north of Wright is the crater Pettit. The outer rim of Wright is somewhat irregular, with an outward bulge along the northeastern side. The rim is sharp-edged, and the inner walls have slumped down to form a shelf along parts of the side. The interior floor is uneven surfaced, particularly in the eastern half. The satellite crater Wright A lies about half a crater diameter to the south-southwest, along the edge of the Montes Cordillera. Due to the location of this crater, it is viewed nearly edge-on from Earth, limiting the amount of detail that can be seen. In addition, this crater can sometimes become hidden from sight due to libration of the Moon in its orbit. Satellit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...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 ...

Wright (Martian Crater)
Wright is an occupational surname originating in England. The term 'Wright' comes from the circa 700 AD Old English word 'wryhta' or 'wyrhta', meaning worker or shaper of wood. Later it became any occupational worker (for example, a shipwright is a person who builds ships), and is used as a British family name. The word's use as an occupational title continued until the mid-19th century, often combined with other words such as in shipwright, wheelwright, wainwright and playwright. '', Wright'' was the eleventh most common surname in England. The word ''carpentier'', now "carpenter", was introduced into England in the years after the Norman conquest in 1066 and slowly replaced the traditional name and meaning of wright in most of England. 'Wright' is still used in Scottish English in the original meaning of 'skilled woodworker'. The Incorporation of Wrights of the Trades House of Glasgow, and the Incorporation of Wrights and Masons of Edinburgh Trades retain the word in its o ...

1747 Wright
1747 Wright, provisional designation , is a stony asteroid and a sizable Mars-crosser, approximately 6 kilometers in diameter. It was discovered on 14 July 1947, by American astronomer Carl Wirtanen at Lick Observatory on Mount Hamilton near San Jose, California. It was named in memory of astronomer William Hammond Wright. Orbit and classification ''Wright'' orbits the Sun at a distance of 1.5–1.9 AU once every 2 years and 3 months (816 days). Its orbit has an eccentricity of 0.11 and an inclination of 21 ° with respect to the ecliptic. As no precoveries were taken and no previous identifications were made, ''Wright's'' observation arc begins with its official discovery observation at Mount Hamilton in 1947. Physical characteristics Spectral type and mineralogy In the SMASS taxonomic system, ''Wright'' is an Sl-type, which transitions between the common stony S-type and the less common L-type asteroids. In the Tholen classification, this asteroid could no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libration
In lunar astronomy, libration is the wagging or wavering of the Moon perceived by Earth-bound observers and caused by changes in their perspective. It permits an observer to see slightly different hemispheres of the surface at different times. It is similar in both cause and effect to the changes in the Moon's apparent size due to changes in distance. It is caused by three mechanisms detailed below, two of which cause a relatively tiny physical libration via tidal forces exerted by the Earth. Such true librations are known as well for other moons with locked rotation. The quite different phenomenon of a trojan asteroid's movement has been called ''Trojan libration''; and ''Trojan libration point'' means Lagrangian point. Lunar libration The Moon keeps one hemisphere of itself facing the Earth, due to tidal locking. Therefore, the first view of the far side of the Moon was not possible until the Soviet probe Luna 3 reached the Moon on October 7, 1959, and further lunar exp ...

Pettit (lunar Crater)
Pettit is a lunar impact crater that lies near the western limb of the Moon. It was named after American astronomer Edison Pettit. In this location the crater is viewed nearly from the side by observers on Earth, and visibility can be significantly affected by libration effects. The crater lies among the rugged features of the Montes Rook, the inner ring of mountains that surround the Mare Orientale impact basin. It is nearly a twin of the crater Nicholson which lies less than one crater diameter to the northeast. Another similar formation is Wright almost due south. The rim of this crater has something of the appearance of a rounded hexagon, with slightly flattened rims to the east and west. The rim is sharp-edged, and the inner wall material has slumped down to lie in a pile around the base. The interior floor is a rugged jumble, with a small central peak and hills to the north and west. Beyond the rim lies rugged terrain to the north and west, while the ground becomes less jumb ...
