Curiosity Rover Enters Precautionary Safe Mode

The team operating NASA’s Curiosity Mars rover is taking steps to return the rover to full activity following a precautionary stand-down over the Fourth of July weekend. Curiosity is now communicating with ground controllers and is stable. The rover put itself into safe mode on July 2, ceasing most activities other than keeping itself healthy and following a prescribed sequence for resuming communications. Engineers are working to determine the cause of safe-mode entry. Preliminary information indicates an unexpected mismatch between camera software and data-processing software in the main computer. The near-term steps toward resuming full activities begin with requesting more diagnostic information from Curiosity.”
