Spirit Begins its Journey to Columbia Hills - Universe Today
Once Spirit wraps up its observations of Crater Bonneville, it will begin the long journey to reach the Columbia Hills, located 2.3 kilometres away. The trip is likely to take 2-3 months, because the rover will stop along the way to analyze anything of interest; some potential targets are a few smaller craters and some trails left by dust devils. The rover's final task at Bonneville will be to analyze some light-coloured rock on the crater's rim. Spirit has been on the surface of Mars for 12 weeks now.
