Autonomous Rover Technology for Mars Sample Return

Planetary rovers enable good sample selection and retrieval for Mars sample return missions. After landing, the rovers search for the best possible scientific samples in the region around a lander, and they return these selected samples to an ascent vehicle that launches the samples into Mars orbit. To streamline the search for, the acquisition, and the retrieval of samples, rover autonomy is a critical technology. This paper summarizes a series of experimental results in the evaluation and demonstration of planetary rover autonomy, with a particular emphasis on rover system technology capabilities under development for a 2005 Mars sample return mission and its precursor missions.
