Dr. Hastings’ recent research has concentrated on issues of space systems and space policy, and has also focused on issues related to spacecraft-environmental interactions, space propulsion, space systems engineering, and space policy. He has published many papers and a book in the field of spacecraft-environment interactions and several papers in space propulsion and space systems. He has led several national studies on government investment in space technology. Dr. Hastings is a Fellow of the AIAA and a member of the International Academy of Astronautics. He is serving as a member of the National Science Board, the Applied Physics Lab Science and Technology Advisory Panel, as well as the chair of Air Force Scientific Advisory Board. He is a member of the MIT Lincoln Laboratory Advisory Committee and is on the Board of Trustees of the Aerospace Corporation.
