Title: Spirit's Extended-Mission Destination Caption: The route planned for NASA's Mars Exploration Rover Spirit to drive during its extended mission is the green line in this traverse map. The gold line traces the path Spirit drove during its prime mission of 90 sols. One objective for the rover's extended mission is to continue eastward to reach the high ground informally named "Columbia Hills," still about 2 kilometers (1.2 miles) away at the beginning of the extended mission. The base image for this map was taken from orbit by Mars Global Surveyor. The entire area is within Gusev Crater. Image credit: NASA/JPL/MSSS/New Mexico Museum of Natural History
