Spirit rover clocks up six years on Mars

Still battling on from Red Planet sand trap

NASA's Spirit Mars rover today passes its sixth anniversary on the Red Planet, albeit bogged down in sandy soil which looks likely to be its final resting place.

Spirit arrived on Mars at 8:35 pm PST on 3 January, 2004 (04:35 GMT on 4 January), followed by its twin Opportunity on 24 January. The pair were intitially expected to last three months, but have proved they have the Right Stuff by surviving "six Earth years, or 3.2 Mars years", as NASA puts it

However, Spirit got stuck in a sand trap dubbed "Troy" in Mars's southern hemisphere back in April. Having already suffered a right-front wheel failure in 2006, its right-rear wheel then succumbed to intermittent failure. NASA explains: "Drives with four or five operating wheels have produced little progress toward escaping the sand trap. The latest attempts resulted in the rover sinking deeper in the soil."
