Later this year, the Mars Rover Curiosity is scheduled to begin its longest road trip yet, to Mount Sharp.  That’s a three-mile-high mountain on Mars that tells the planet’s geologic history in the same way the Grand Canyon’s exposes earth’s.  But getting Curiosity to its ultimate destination depends on maps and cameras.  That’s where Flagstaff’s office of the U.S. Geological Survey comes in.
