  • Spiders Invade Mars
    As the Sun peeks above the horizon at the martian south polar icecap, powerful jets of carbon-dioxide gas erupt through the icecap's topmost layer. If you were there, you'd feel a vibration through your spacesuit boots as, all around you, roaring jets of CO2 gas

  • Waiting for Martian Spring
    Solar power levels have plunged during the rovers' second martian winter, yet Spirit has been producing a steady stream of scientific data, while Opportunity continues to advance toward Victoria Crater, the largest crater yet visited on the surface of Mars.

  • Hydrogen Peroxide Snow
    The planet-wide dust storms that periodically cloak Mars in a mantle of red may be generating a snow of corrosive chemicals, including hydrogen peroxide, that would be toxic to life, according to two new studies published in the most recent issue of the journal Astrobiology.

  • Sunning Frozen Soil
    The answer to the question about life on Mars may very well come from analyzing an unsuspecting source - the soil, specifically the icy layer of soil underneath the red planet's surface.

  • An Automated DAME
    NASA scientists plan to drill someday into the surface of Mars to look for water and signs of possible life. So, scientists are developing an automated, unmanned drill rig that can operate totally on its own, unsupervised for hours at a time.

  • Spirit Spies Meteorites?
    From its winter outpost at "Low Ridge" inside Gusev Crater, NASA's Mars Exploration Rover Spirit took this spectacular, color mosaic of hilly, sandy terrain and two potential iron meteorites. The two light-colored, smooth rocks about two-thirds of the way up from the bottom of the

  • Shine of Life
    New research reveals that the dark coating known as desert varnish creates a record of life around it, by binding traces of DNA, amino acids and other organic compounds to desert rocks. Samples of Martian desert varnish could therefore show whether there has been life
