Water on Mars

NASA's Mars rover, Curiosity, has discovered gravel once carried by the waters of an ancient stream that "ran vigorously" through the area. Scientists had previously found other evidence of the one-time presence of water on the Red Planet, but the US space agency says this is the first time stream-bed gravels have been discovered.

Pictures transmitted by Curiosity show the pebbles have been cemented into layers of conglomerate rock at a site between the north rim of the Gale Crater and the base of Mount Sharp - where Curiosity is heading.

Curiosity science co-investigator Rebecca Williams says the sizes and the shapes of the rocks give an idea of the speed and the depth of the stream. "The shapes tell you they were transported, and the sizes tell you they couldn't be transported by wind," she said."They were transported by water flow."
