Spirit Wraps Up a Martian Year of Exploration
NASA's Spirit rover recently celebrated its one year anniversary on the surface of Mars... that's one Martian year. Spirit has now been exploring the Red Planet for more than 669 days. Not bad considering the rovers were only expected to perform for 60-90 days until their solar panels became so clogged with dust they wouldn't function. And even after surviving more than 7-times their expected lifetimes, Spirit and its twin Opportunity are still going strong, and should be returning much more science.
