Water on Mars


  1. Almost all water on Mars today exists as ice.
  2. Small quantities as vapor in the atmosphere.
  3. The only place where water ice is visible at the surface is at the north polar ice cap

Some liquid water may occur transiently on the Martian surface today, but limited to traces of dissolved moisture from the atmosphere and thin films, which are challenging environments for known life
