NASA's
Curiosity rover has found new evidence of water on Mars, indicating that the
planet most like Earth in the solar system was suitable for microbial life.
Pictures and other data collected by
NASA's Mars rover Curiosity show that rivers once flowed into a lake or lakes
at the bottom of Gale Crate, an enormous dimple carved out by an incoming space
rock.

NASA said its interpretation of
Curiosity's finds in Gale Crater suggests ancient Mars maintained a climate
that could have produced long-lasting lakes at many locations on the Red
Planet.
The American space agency said Mars's Mount Sharp
was built by sediments deposited in a large lake bed over tens of millions of
years.
Mount Sharp stands about three miles (5 kilometers) tall,
its lower flanks exposing hundreds of rock layers.
Curiosity currently is investigating
the lowest sedimentary layers of Mount Sharp, a section of rock 500 feet (150
meters) high dubbed the Murray formation.
