NASA's Curiosity rover will soon begin a five-mile trek to the base of Mars' Mount Sharp. The $2.5 billion rover has already found evidence of water flow in the Gale Crater and drilled rocks that revealed evidence of stream-deposited clay. "We are on our way to Mount Sharp, but we are on a mission of exploration. If we find something of interest, we will explore it along the way," said Project Manager Jim Erickson of NASA's Jet Propulsion Laboratory.
