The maps below were produced by the Mars Global Surveyor ' s Mars Orbiter Laser Altimeter; redder colors indicate higher elevations.The maps of the equatorial quadrangles use a Mercator projection, while those of the mid-latitude quadrangles use a Lambert conformal conic projection, and the maps of the polar quadrangles use a polar stereographic projection.
Martian meteorites have provided datable samples that are consistent with ages calculated thus far, [8] but the locations on Mars from where the meteorites came (provenance) are unknown, limiting their value as chronostratigraphic tools. Absolute ages determined by crater density should therefore be taken with some skepticism.
Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
Marte Vallis is a valley in the Amazonis quadrangle of Mars, located at 15 North and 176.5 West. It is 185 km long and was named for the Spanish word for "Mars". [ 2 ] It has been identified as an outflow channel , carved in the geological past by catastrophic release of water from aquifers beneath the Martian surface. [ 3 ]
NASA released a stunning image on Friday showing our home planet as well as the moon from Mars.
The quadrangle is also referred to as MC-10 (Mars Chart-10). [1] Lunae Planum and parts of Xanthe Terra and Chryse Planitia are found in the Lunae Palus quadrangle. The Lunae Palus quadrangle contains many ancient river valleys. The quadrangle covers the area from 45° to 90° west longitude and 0° to 30° north latitude on Mars.
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9] Layers can be hardened by the action of groundwater.
The Curiosity rover has been poking around the Gale crater on Mars for a few years now, and it turns out the place may be more similar to Earth than we originally thought. Using rock data gathered ...
