Tinjar Vallis
The Tinjar Valles are an ancient set of outflow channels in the Amenthes quadrangle of Mars, located at 38° north latitude and 235.8° west longitude. They are 425 km long and were named after a modern river in Sarawak, Malaysia. They have been identified as outflow channel Outflow channels are extremely long, wide swathes of scoured ground on Mars. They extend many hundreds of kilometers in length and are typically greater than one kilometer in width. They are thought to have been carved by huge outburst floods. ...s.Carr, M.H.

Outflow Channel
Outflow channels are extremely long, wide swathes of scoured ground on Mars. They extend many hundreds of kilometers in length and are typically greater than one kilometer in width. They are thought to have been carved by huge outburst floods. Crater counts indicate that most of the channels were cut since the early Hesperian, though the age of the features is variable between different regions of Mars. Some outflow channels in the Amazonis and Elysium Planitiae regions have yielded ages of only tens of million years, extremely young by the standards of Martian topographic features. The largest, Kasei Vallis, is around long, greater than wide and exceeds in depth cut into the surrounding plains. The outflow channels contrast with the Martian channel features known as " valley networks", which much more closely resemble the dendritic planform more typical of terrestrial river drainage basins. Outflow channels tend to be named after the names for Mars in various ancient w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amenthes Quadrangle
The Amenthes quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Amenthes quadrangle is also referred to as MC-14 (Mars Chart-14). The quadrangle covers the area from 225° to 270° west longitude and from 0° to 30° north latitude on Mars. Amenthes quadrangle contains parts of Utopia Planitia, Isidis Planitia, Terra Cimmeria, and Tyrrhena Terra. The name Amenthes is the Egyptian word for the place where the souls of the dead go. This quadrangle contains the Isidis basin, a location where magnesium carbonate was found by MRO. This mineral indicates that water was present and that it was not acidic. There are Dark slope streaks, troughs (fossae), and river valleys ( Vallis) in this quadrangle. The Beagle 2 lander was about to land in the quadrangle, particularly in the eastern part of Isidis Planitia, in December 2003, when contact with the craft was lost. In January 2015 ...

Sarawak River
The Sarawak River ( ms, Sungai Sarawak) is a river in Sarawak, Malaysia. It is an important source of water and transportation for the inhabitants in southwestern Sarawak. The river is also used for water-related sport activities such as the annual Sarawak Regatta which attract tourists from all over the world. The Astana, the official residence of the Yang di-Pertua Negeri Sarawak (Governor of Sarawak) and the New Sarawak State Legislative Assembly Building is located on the north bank of the river as well as Fort Margherita. It runs around Holiday Inn Kuching Kuching (), officially the City of Kuching, is the capital and the most populous city in the state of Sarawak in Malaysia.

USGS Astrogeology Science Center
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 Uni ...

Valleys And Canyons On Mars
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. ...
