He previously served as a program officer on the Space Studies Board. He has also written extensively on the history of American satellite reconnaissance. Career He received a doctorate degree in political science from The George Washington University where he specialized in space policy and management of the national security bureaucracy. His dissertation, "Mission Control," concerned how President Dwight D.

Day has written many articles in space magazines including Spaceflight, Quest, Novosti Kosmonavtiki and other publications such as Space News. He is an associate editor of the German spaceflight magazine Raumfahrt Concret. Day published the book Eye in the sky about the CORONA spy satellite program, and was investigator for the Columbia Accident Investigation Board, where he focused on the policy, budgetary, managerial and institutional causes of the Columbia accident. Day is regarded as one of a handful of experts on the history of the U.S. military space program, particularly American intelligence satellites. Among his contributions in this area is the first publication of a photograph of a satellite launched during a classified Space Shuttle launch, the first discussion of the evolution of the early American electronic intelligence satellite programs during the 1960s, and the first detailed discussion of the Satellite Data System communications relay satellites used by the National Reconnaissance Office.
