Future planetary rover missions, such as the upcoming Mars Science Laboratory, will require rovers to autonomously navigate to science targets specified from up to 10 meters away, and to place instruments against these targets with up to 1 centimeter precision. The current state of the art, demonstrated by the Mars Exploration Rover (MER) mission, typically requires three sols (Martian days) for approach...
