Synergies of Robotic Asteroid Redirection Technologies and Human Space Exploration

This paper summarizes the results of a 2014 KISS workshop that identified a wide variety of ways that the technologies (and their near-term derivatives) developed for the proposed Asteroid Redirect Mission (ARM) would beneficially impact the Nation’s space interests including: human missions to Mars and its moons, planetary defense, orbital debris removal, robotic deep-space science missions, commercial communication satellites, and commercial asteroid resource utilization missions. This wide applicability of asteroid retrieval technology is, in many ways, is just as surprising as was the initial finding about the feasibility of ARM. The current Asteroid Redirect Mission concept consists of two major parts: the development of an advanced Solar Electric Propulsion (SEP) capability and the retrieval of a near-Earth asteroid. The improvement in SEP technology required by ARM provides an extensible path to support human missions to Mars, is applicable to all planetary defense techniques, could reduce the time required for the LEO-to-GEO transfer of large commercial or military satellites, would enable new deep space robotic science missions, and could enable affordable removal of large orbital debris objects. The asteroid retrieval part of ARM would greatly improve the understanding of the structure of rubble-pile asteroids necessary to evaluate the effectiveness of primary asteroid deflection techniques, demonstrate at least one secondary asteroid deflection technique, greatly accelerate the use of material resources obtained in space to further space exploration and exploitation, and further planetary science.
