NASA scientists confirmed Tuesday that Mars rover Opportunity had found evidence indicating the presence of water on the Red planet, though no direct traces of living organisms have been found so far, report agencies.
"NASAlaunched the Mars Exploration Rover mission specifically to check whether at least one part of Mars had a persistently wet environment that could possibly have been hospitable to life," said NASA scientist James Garvin. 'Today we have strong evidence for an exciting answer: Yes."
Adetailed examination of rock surfaces by the rover, which landed on the Red planet five weeks ago, indicated the presence of minerals and sulfates that form in the presence of water. But no direct evidence of life was found.
The unmanned six-wheeled rover and its twin, Spirit, are controlled and moderated by scientists working at the Jet Propulsion Laboratory in Pasadena, California.
