SPIRIT UPDATE: Roving Toward the Hills - sol 143-144, June 03, 2004
Spirit began sol 143 using the panoramic camera to image its surroundings. After a restful nap, the rover began driving and advanced 69 meters (226.4 feet) in an engineer-directed drive toward the "Columbia Hills." After doing some mid-drive science imaging, Spirit attempted additional driving using its autonomous navigation software, but detected hazards in the immediate vicinity of the rover and therefore covered no additional ground.
On sol 144, Spirit covered 24.4 meters (80 feet) in another engineer-directed drive. Once again, the terrain was too rough to permit further driving beyond this point using the autonomous navigation software. On sol 145, Spirit will continue driving in its quest for the hills.
