REST IN PEACE: NASA officially says goodbye to its Mars rover, Opportunity: Communication attempts have been unsuccessful for nearly a year now. “Opportunity went far beyond what anyone thought it would be able to withstand. NASA wanted this rover and its identical twin named Spirit to last 90 days. After 15 years and over 28 miles of martial terrain traveled, Opportunity is the most traveled and longest lasting rover ever launched to another planet.”

UPDATE: Much, much more here.
