NASA Readies Long-Distance Fix for Rover’s 'Amnesia'

NASA engineers are planning to send a software fix to a rover that has been working on Mars for nearly 11 years longer than expected.
The Mars rover Opportunity has been suffering from a glitch that's causing what NASA scientists describe as memory and data loss -- or a robotic "amnesia" -- since early December. Now, they're nearly ready to send aloft a software update they hope will rectify the problem.
