The Mars Reconnaissance Orbiter or MRO seems to be having a few issues. The $720 million dollar mission is on hold while scientists try and determine why the system keeps rebooting. In fact the MRO has had 4 computer resets this year before NASA scientists put the spacecraft in to safe mode. While in safe mode the spacecraft has its solar arrays tracking the sun and communications antennae pointed at Earth to allow additional communications and software uplinks.
