SUMMARY: Engineers with NASA have decided to get Spirit to drive up the Columbia Hills backwards because of an ongoing problem with one of its wheels. The problem cropped up a few months ago, when one of its front wheels started getting extra resistance; they've tried heating it, and giving it rest, but nothing's worked. Spirit is now keeping the wheel locked, and then driving backwards, dragging it along like an anchor. This has saved power, but slowed down its speed a bit. Spirit will still use the wheel when it's trying to cross difficult terrain.
