After 18 months of driving, scientists on September 11, 2014, announced that Curiosity had arrived at the base of Mount Sharp ahead of schedule, thanks to a somewhat serendipitous decision to take an alternative path that would be gentler on the rover's damaged wheels. Within two weeks, Curiosity will reach an outcrop of rock called Pahrump Hills, where the first drill samples of Mount Sharp real estate will be made. Reuters/NASA/JPL-Caltech/MSSS/
