Mars rover Curiosity found rocks on the Martian surface that are too big to be carried by wind, so researchers suppose water must have existed on Mars at one time. Over the next two years, Curiosity will continue its search for signs of ancient microbial life on Mars.
On Thursday, NASA's Mars Curiosity rover identified what are believed to be rocks moved by water that once flowed on the Red Planet. Curiosity's further exploration is hoped to determine whether Mars was once inhabited by microorganisms.
