Scientists Excited By New Mars Rovers Discoveries

NASA scientists say the Mars rovers mission has gotten "fairly wild" with new discoveries.

Steve Squyres, a Cornell University astronomer and the chief scientist for the mission, says it feels "like the mission has started over again."

The rover named "Spirit" has arrived at a site dubbed "Columbia Hills" and found a very rare rock formation. Squyres says scientists have named the rock "Pot-of-Gold" and are baffled by its structure. He says it has "little nuggets on the end of stalks," and no one knows what they are.

Meantime, the rover named "Opportunity" has discovered new evidence of water in "Endurance Crater" where it's been exploring. Squyres says the findings suggest there was more water than had been earlier believed, with periods of wetting and drying.
