Bibliographical noteThis paper is dedicated to Dr. Michael J. Wargo at NASA HQ, who passed away unexpectedly on 4 August 2013. Mike was Chief Exploration Scientist in the Human Exploration and Operations Mission Directorate (HEOMD) and an enthusiastic supporter of collaborative projects between Science and Exploration. He was a strong supporter of RAD and a valuable member of both the science and exploration communities. He was a good friend and a wonderful human being, and he will be greatly missed. RAD is supported by NASA under Jet Propulsion Laboratory (JPL) subcontract 1273039 to Southwest Research Institute and in Germany by Deutsches Zentrum fur Luft- und Raumfahrt (DLR) and DLR’s

Moore, V. Friedensen, and R. Williams at NASA HQ; and H. Witte at DLR in Germany for their unwavering support of RAD over the years. The authors also thank the reviewers for their careful and thoughtful comments and suggestions.
