Apsus Vallis
Apsus Vallis is a channel in the Cebrenia quadrangle of Mars, located at 35.1° north latitude and 225° west longitude. It is 120 km long and was named after a classical river in ancient Macedonia, the present-day Seman River. References Cebrenia quadrangle Valleys and canyons on Mars {{Mars-stub ...

Cebrenia Quadrangle
The Cebrenia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the northeastern portion of Mars’ eastern hemisphere and covers 120° to 180° east longitude (180° to 240° west longitude) and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Cebrenia quadrangle is also referred to as MC-7 (Mars Chart-7). It includes part of Utopia Planitia and Arcadia Planitia. The southern and northern borders of the Cebrenia quadrangle are approximately and wide, respectively. The north to south distance is about (slightly less than the length of Greenland). The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars’ surface area. Origin of name Cebrenia is a telescopic albedo feature centered on 50° N and 150° E on Mars. The feature is named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seman River
The Seman is a major river in western Albania. It is formed by the confluence of the rivers Devoll and Osum, a few km west of Kuçovë. It is long ( with its longest source river Devoll) and its drainage basin is . Its average discharge is . It meanders generally westwards through a flat lowland. Near Fier it receives Gjanica from the left. It flows into the Adriatic Sea at the southern margin of the Divjakë-Karavasta National Park. Name In classical antiquity, the Seman River was known as the ''Apsus'', which is a derivative of the Indo-European root ''*ăp-'' "water, river". The Illyrian hydronym ''Apsus'', corresponds to ''Apsias'', a river name in southern Italy brought by Illyrian migrations (Iapygians) in the region. The contemporary Albanian name ''Seman/Semen'' ( definite form: ''Semani/Semeni''), which is used to indicate the lower course of the river, evolved from ''*Apson-'' through Albanian phonetic changes. Also the contemporary Albanian name ''Osum'' (definite f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrogeology Research Program
The Astrogeology Science Center is the entity within the United States Geological Survey concerned with the study of planetary geology and planetary cartography. It is housed in the Shoemaker Building in Flagstaff, Arizona. The Center was established in 1963 by Eugene Merle Shoemaker to provide lunar geologic mapping and to assist in training astronauts destined for the Moon as part of the Apollo program. Since its inception, the Astrogeology Science Center has participated in processing and analyzing data from various missions to the planetary bodies in the Solar System, assisting in finding potential landing sites for exploration vehicles, mapping our neighboring planets and their moons, and conducting research to better understand the origins, evolutions, and geologic processes operating on these bodies. The Early Days Gene Shoemaker founded the Astrogeology Research Program August 25, 1960. The research program started out as the ''Astrogeologic Studies Group'' at the U ...

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 hundredth an ...
