NASA: Primitive Live May Have Existed on Mars

It's official: Primitive life could have lived on ancient Mars, NASA says.

A sample of Mars drilled from a rock by NASA's Curiosity rover and then studied by onboard instruments "shows ancient Mars could have supported living microbes," NASA officials announced Tuesday in a statement and press conference.

The discovery comes just seven months after the Curiosity rover landed on Mars to spend at least two years determining if the planet could have ever supported primitive life.
