Power Drain Threatening Mars Rover Lifespan Reuters

Engineers must replace software in the Mars rover Opportunity to stop a power-draining malfunction that could cut short the robot geologist’s life on the Red Planet, a NASA official said on Wednesday. A switch that operates an onboard heater has been stuck in the “on” position since shortly after the golf cart-sized rover landed at the Meridiani Planum near Mars’ equator on Jan. 24, 2004.
