NASA discovers salty sea on Mars

body of salty water once existed on Mars' surface, and the sea may have supported life at one point, scientists from the US space agency said Tuesday.
The Mars rover Opportunity found rocks with a layering pattern, signs that they were formed in standing water. The rocks, found near the rover's landing site, also contained chlorine and bromine, further evidence that water covered the surface when the rocks were formed, scientists with the National Aeronautics and Space Administration (NASA) said.

"We think Opportunity is now parked on what was once the shoreline of a salty sea on Mars," said Steve Squyres, the principal investigator for the science payload on Opportunity and its twin rover, Spirit.
