NASA's Mars Opportunity Rover May Be Dying

NASA/JPL-Caltech/Cornell Univ. /Arizona State Univ. A global dust storm has been raging on Mars since June. The Opportunity rover began hibernating on June 10th to wait out the storm, but it has yet to wake up and call NASA. If the robot can't get enough sunlight, its batteries may brown out or lack the electricity to power heaters. Blistering cold on Mars can snap electronic circuits inside Opportunity if they aren't warmed.
