The final results of the Rover research will be reported next year, but a growing body of evidence shows that Mars had a great deal of water several billion years ago, about the same time life was emerging on Earth.

LIVELY MARS : ET might just be out there. NASA&#39;s two Mars rovers, Opportunity and Spirit, landed on the Red Planet early in 2004 and have since found conclusive evidence of water that could possibly have harboured life.

NASA experts said they have detected evidence that liquid water existed on the surface of Mars in recent years, giving weight to hopes that signs of life on the Red Planet could still be found.

Researchers can now say definitively that Mars once  supported a watery environment, but whether the red planet could have ever  supported life is still far from certain.

An orbiting spacecraft has sent back new evidence for the presence of water on Mars. Scientists long have debated whether water flowed on the red planet, with evidence increasing in recent years. The presence of water would raise the possibility of at least primitive life forms existing there.

LOS ANGELES - NASA&#39;s Mars rover, Opportunity, has found more signs that rocks on the Red Planet were once submerged in water. Data sent by Opportunity suggest a crater was drenched a second time after drying out, scientists said.

JACKSON HOLE, Wyoming -- There is mounting evidence of the role of water  in Mars' evolution. That fact appears to have been favorable to the  development of life -- and the leftover calling card of past biology may be  preserved in that world's geologic record.
