Mars rovers Spirit and Opportunity continue to function and are sending back intriguing data from the surface of the red planet.
Spirit, having trekked nearly two miles across the flat terrain of the vast Gusev Crater region where it set down, is zigzagging up the rugged Columbia Hills and is now nearly 200 feet above the surrounding plain.
Opportunity is nearing the end of its exploration of stadium-size Endurance Crater in the Meridiani Planum region and may claw its way over the rim.

I was just reading about that today. Very cool that the little dudes are still going.
