	<htmltext>coondoggie writes <i>"NASA today said it <a href="http://www.networkworld.com/community/node/58913">upgraded the software controlling its Mars Rover</a> Opportunity to let it make its own decisions about what items like rocks and interesting red planet formations to focus its cameras on.  The new system, which NASA uploaded over the past few months, is called Autonomous Exploration for Gathering Increased Science, or AEGIS and it lets Opportunity's computer examine images that the rover takes with its wide-angle navigation camera after a drive, and recognize rocks that meet specified criteria, such as rounded shape or light color. It can then center its narrower-angle panoramic camera on the chosen target and take multiple images through color filters, NASA stated."</i></htmltext>

	<htmltext>I'm sure they have a rudimentary OS in the rover, which likely remains unchanged. They probably designed the rovers with future updates in mind, and fail-safes for bad flashes due to solar interference, etc.
Even if not, NASA presumably designed a very simple earth communications interface to be a separate system from the mechanical controller, so even if the robot gets stuck in a loop or something there is a from-earth reset button.</htmltext>
