PASADENA, Calif., Feb. 7 (UPI) -- The Mars rover Curiosity successfully negotiated its way across the largest sand dune it has encountered, NASA said.
Riding the dune, about a yard high and 10 yards long, was risky, NASA scientists said. It was chosen as an alternate route around terrain -- called the "rapid transit route" -- that has been causing holes, scratches and other damage to the rover's aluminum wheels.
