COLLEEN HARTMAN is the Director of the Aeronautics and Space Engineering Board (ASEB) and the Space Studies Board (SSB) of the U.S. National Academies of Sciences, Engineering, and Medicine. Dr. Hartman has served in various senior positions, including Acting Associate Administrator, Deputy Director of Technology and Director of Solar System Exploration at NASA’s Science Mission Directorate and Deputy Assistant Administrator at the National Oceanic and Atmospheric Administration. Dr. Hartman was instrumental in developing innovative approaches to powering space probes destined for the farthest reaches of the solar system, including in‐space propulsion and nuclear power and propulsion. She also gained administration and congressional approval for an entirely new class of competitively selected missions called "New Frontiers," to explore the planets, asteroids and comets in the Solar System. Dr. Hartman has built and launched balloon and spacecraft payloads, worked on robotic vision, and served as Program Manager for dozens of space missions, including the Cosmic Background Explorer (COBE). Data from the COBE spacecraft gained two NASA‐sponsored scientists the 2006 Nobel Prize in Physics. Dr. Hartman earned a bachelor's degree in zoology from Pomona College in Claremont, Calif., a master's in public administration from the University of Southern California, and a doctorate in physics from the Catholic University of America. She started her career as a Presidential Management Intern under Ronald Reagan. Her numerous awards include the Claire Booth Luce Fellowship in Science and Engineering, the NASA Outstanding Performance Award, and multiple Presidential Rank Awards, one of the highest awards bestowed by the President of the United States to senior executives.
