  • Dark streaks that grow in summer on sun-scorched slopes suggest there is water in the Martian tropics, once assumed dry. If so, it could be harder to protect them from contamination by earthly life forms, a finding that could shape future exploration. The latest pictures from NASA's Mars Reconnaissance Orbiter double the number of southern sites with streaks and add some near the equator.
