Riding with Robots writes "When the robotic geologist Spirit found the latest evidence for a wet Mars, 'You could hear people gasp in astonishment,' said Steve Squyres, the lead scientist for the Mars rovers. 'This is a remarkable discovery. And the fact that we found something this new and different after nearly 1,200 days on Mars makes it even more remarkable. It makes you wonder what else is still out there.' The latest discovery, announced today, adds compelling new evidence for ancient conditions that might have been favorable for life, according to the rover team."
