One of two Martian rovers, Spirit, may be in its final days. Sent to Mars on a
90-day mission, over five years later, the rovers Spirit and Opportunity were
still exploring, scaling mountains and crater walls and defying all expectations
of how long they would last. NASA researchers may now know the answer to that
crucial question for one of the robot explorers. Spirit is bogged down in the
Martian sands. All imaginative but desperate attempts to free her have failed.
Spirit may be doomed. Unable to move into position to recharge her solar
batteries for the sun-starved winter on Mars, Spirit could slip into hibernation
and lack the energy to awake. The engineers still have a few tricks to try but
theyre running out of time. NASAs not sure Spirit can be saved.
