He is also a senior member of the Association Aeronautique et Astronautique de France, co-founder of Association Planet Mars, co-founder and president since 2007 of the Institut Francais d'Histoire de l'Espace, and a member of the history committee of International Academy of Astronautics.
James Oberg was born in New York in 1944, and in 1969 got a Masters in applied mathematics from Northwestern University. After service with the US Air Force he joined NASA in 1975 and worked at the Johnson Space Center until 1997. As a child 'space nuts,' Sputnik inspired his early private study of Soviet spaceflight, an interest later encouraged by mentors such as Charles Sheldon of the Congressional Research Service. He became one of the original sleuths in his spare time after writing dozens of articles, authoring the ground-breaking book Red Star in Orbit and circulating a sleuthing newsletter called Cosmogram. At JSC he was an orbital rendezvous mission controller, receiving professional awards for his work relating to the ISS orbit. He has authored ten books and is currently a consultant for NBC News, which recently took him to North Korea's secret launch site. He lives in rural Texas with his wife Alcestis ('Cooky') Oberg, herself a published author.
