Since August, NASA's Curiosity rover has been exploring a giant Martian crater with a mountain in the middle. Scientists announced in late September that if the rover had arrived at this spot 3.5 billion years earlier, it might have landed with a splash. Curiosity seems to have landed in the middle of a former streambed.
The moving water would have been ?from ankle to hip deep, and maybe moving a few feet a second,? planetary scientist William Dietrich told Science News. Dietrich works with other scientists on the Curiosity mission.
