Mars Rovers strike again!
Kudos to Slashdot for alerting me to this one, those fabulous little guys the Mars Rovers, Spirit and Opportunity, have found yet more evidence that there used to be a lot of water on Mars. Perhaps not earthshaking (marsshaking?) in itself, but it’s amazing that these guys have gone for twice as long as anyone expected, are still going strong, and are still producing valuable data. Pretty neat!
