    NASA's Mars rover Opportunity is scheduled to begin a descent down a rock-paved slope into the Red Planet's massive Victoria Crater. This carries real risk for the long-lived robotic explorer, but NASA and the Mars Rover science team expect it to provide valuable science.

  • Cave Skylights Spotted on Mars

    2007April 6, 2011

    NASA's Mars orbiters have spotted "skylights" apparently leading to cavernous underground spaces on Mars. The discovery is fueling interest in potential underground habitats and sparking searches for caverns elsewhere on the Red Planet.
