In 1959, he worked at the Army Ballistic Missile Agency (ABMA) as an aerospace engineer. He joined NASA and finalized his divorce in 1960, working on launching satellites at Marshall Space Flight Center (MSFC), eventually becoming Chief of the Systems, Performance, and Analysis Office for the Centaur Program. His work in the NASA space program became instrumental in the development of space landing craft, which helped us land on the moon. From 1963 to 1965, he became the Contracting Officer Representative for the MOLAB (Mobile Laboratory) and the Mobility Test Articles (MTA) of the mobility systems of the MOLABs. In 1969, he transferred to NASA?s Headquarters, working in the Advanced Mission program and later the IUS Office, Expendable Launch Vehicles, and Upper Stages.
