LOS ANGELES, California (Reuters) -- As NASA scientists pored over striking new photos from Mars revealing finely layered formations of ancient bedrock, engineers labored on Tuesday to diagnose problems with two robotic rovers on opposite sides of the red planet.
Besides a serious malfunction that has idled the first rover, Spirit, since last Wednesday, mission controllers at NASA"s Jet Propulsion Laboratory said they are now contending with a power drain on Spirit"s newly arrived twin, Opportunity.
Mission manager Jim Erickson told reporters said the power loss appeared to be from one of the craft"s heating units that keeps turning itself on and running overnight without receiving commands from NASA to do so.
