Mars Rover Sample Return mission delivery and return challenges

Abstract

The Mars Rover Sample Return mission is a robotic exploration mission culminating in the return of atmospheric and surface samples from Mars to Earth. To accomplish this complex mission requires sophisticated autonomous systems for many time-critical operations associated with the delivery and return phases, since the round trip light times preclude Earth-based control of these operations. In addition, there are significant engineering and technology challenges to be addressed to meet the mission science and exploration objectives.
