Like rust-colored ocean waves frozen in mid-motion, miniature sand dunes sit at the base of Pioneer Mound in this panoramic image, taken by the Spirit rover last month and assembled here by James Canvin.
Spirit has recently started traveling again after a two-week hiatus while engineers on the MER team tried to diagnose some computer problems on the rover. Its operational health seems to check out but the data and hardware issues have not been entirely explained.
Since its landing in 2004, Spirit has traveled over 4.8 miles in its investigation of the Martian surface.
