W. Bond (crater)
W. Bond is an irregularly shaped moon, lunar walled plain that is located in the northern part of the Moon, to the north of the Mare Frigoris. It lies to the east of the crater Birmingham (crater), Birmingham, and south-southwest of Barrow (crater), Barrow. Epigenes (crater), Epigenes is located just to the northwest of the outer rim. Along the southwest edge, between W. Bond and the lunar mare, is the crater Timaeus (crater), Timaeus. What remains of the outer rim of W. Bond has been eroded and reshaped until it now consists of little more than an outline of hills and mounts. The most prominent of these is a nearly linear range along the northwest rim, which is divided in half by the satellite crater Epigenes A.http://planetarynames.wr.usgs.gov/images/Lunar/lac_3_wac.pdf The southeast rim is also relatively well defined, but the remainder is irregular, notched, and not very prominent. The interior floor is relatively flat in comparison with the rim region, although there are se ... [...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, designed to orbit the Moon, after the three previous orbiters had completed the required needs for 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 cislunar trajectory and injected into an elliptical near polar high lunar orbit In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or ...

Rille
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is ''rima'', plural ''rimae''. Typically, a rille can be several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear a structural resemblance to each other. Structures Three types of rille are found on the lunar surface: * Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. , 195 sinuous rilles have been identified on the Moon. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only ... [...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 campaign ...

William Cranch Bond
William Cranch Bond (September 9, 1789 – January 29, 1859) was an American astronomer, and the first director of Harvard College Observatory. Upbringing William Cranch Bond was born in Falmouth, Maine (near Portland) on September 9, 1789. When he was young, his father, William Bond, established himself as a clockmaker after a failed business venture; trained by his father and aided by his penchant for engineering, W. C. Bond built his first clock when he was fifteen years old. He eventually took over his father’s business, becoming an expert clockmaker himself. The William Bond clock shop remained in existence at 9 Park Street in Boston until the 1970s.. Amateur astronomer In 1806, when he was seventeen years old, Bond saw a solar eclipse. Soon thereafter, he became an avid amateur astronomer. When he built his first house, Bond made its parlor an observatory, complete with an opening in the ceiling out of which his telescope could view the sky. Trip to Europe In ...

Lunar Mare
The lunar maria (; singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient asteroid impacts on the far side on the Moon that triggered volcanic activity on the opposite (near) side. They were dubbed , Latin for 'seas', by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features ( Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Proc ...
