On Mars, Getting Ready to Roll Washington Post

As the fit and healthy rover Opportunity sent home its first color snapshot from Mars, engineers reported Monday that its ailing twin, Spirit, seemed to be suffering from a problem familiar to many earthlings: It was trying to manage too many files. Spirit now has spent 23 Martian days, or “sols,” on the planet, the last five or so on sick call, while Opportunity has completed two and will spend a week or two moving cautiously through the steps required for it to stand up and roll off onto “pay dirt,” engineers said.
