Nasa's Mars rover, Curiosity, dispatched to learn if the most Earth-like planet in the solar system was suitable for microbial life, has found clear evidence its landing site was once awash in water, a key ingredient for life, scientists said Thursday.
Scientists suspect the mound, known as Mount Sharp, is the remains of sediment that once completely filled the crater. Analysis of a slab of rock located between the crater's north rim and the base of Mount Sharp indicate a fast-moving stream of water once flowed there.
Images taken by Curiosity and released on Thursday show rounded stones cemented into the rock, which rises like a piece of jack-hammered sidewalk from the planet's surface.
