NASA investigates Curiosity's switch into safe mode

On July 2, NASA's Curiosity Mars rover switched itself into safe mode, ceasing a host of functions including communications with ground control.

It has since begun its automated recovery sequence, and engineers are again able to engage in the relay of information.

Those investigating are in the process of learning what triggered the action and at this time suspect a software conflict related to camera and data processing operations was involved.

This is not the first time Curiosity has engaged in this particular type of self-preservation, during which it focuses solely on what it needs to recoup and rebound.

In 2013, the rover experienced three similar shutdowns.
