Energizer Bunny Rovers

They keep going, and going, and going. This was reported last week but I've been busy and just noticed that Spirit and Opportunity have resumed driving on Mars. JPL operators had the rovers "laying low" to preserve their limited power reserves while long-lasting Martian dust storms darkened the skies and greatly reduced the output of the solar panels. Those panels and other parts of the rovers are still pretty dirty with built up dust, but power levels have reached high enough levels to start driving. These things are amazing!
