What are the surface conditions like on Mars?
June 20, 2016 8:14PM
Dry, rocky, hard, barren, and no water.
Based on orbital observations and the examination of the Martian meteorite collection, the surface of Mars appears to be composed primarily of basalt. Some evidence suggests that a portion of the Martian surface is more silica-rich than typical basalt, and may be similar to andesitic rocks on Earth; however, these observations may also be explained by silica glass. Much of the surface is deeply covered by finely grained iron) oxide dust. Liquid water cannot exist on the surface of Mars due to its low atmospheric pressure, Mars has two permanent polar ice caps.
