NASA's Mars Exploration Rover Spirit took this panoramic camera image mosaic of the "Columbia Hills" at 4:15 p.m. local solar time on sol 122 (May 7, 2004). Spirit will spend the next 37 sols or more approaching the base of the highest peak seen in this image. Rover controllers and scientists are sending Spirit to this faraway location because the hills there are likely an older unit of rock and may provide insight into the past environment at Gusev Crater.
