Mars rover parked at edge of ancient seashore

NASA's Mars rover Opportunity is parked by the shore of what used to be a salty martian sea, scientists say.
'We think Opportunity is now parked on what was once the shoreline of a salty sea on Mars,' said Steve Squyres, principal investigator for the science payload on Opportunity and its twin Mars exploration Rover, Spirit.
"This dramatic confirmation of standing water in Mars' history builds on a progression of discoveries about that most Earthlike of alien planets," said Ed Weiler, NASA associate administrator for space science.
