The San Francisco Chronicle has an update on the status of our two Mars rovers.

Defying all the odds, the gutsy Mars rover Opportunity is still trundling tirelessly across the Red Planet’s rugged landscape and making new discoveries of ancient water 2 1/2 years after it bounced to a landing on a mission designed to last only three months.

The word trundle always makes me think of the Stainless Steel Rat books by Harry Harrison, since it was used several times in there, and I was impressionable at a child.

Anyways, Steve Squyres is still keeping himself busy. Spirit is a bit lamer than his brother, but he’s still chugging along. Go Rovers, go!
