Nonetheless, on 1 March 1970, von Braun and his family relocated to Washington, DC, when he was assigned the post of NASA's Deputy Associate Administrator for Planning at NASA Headquarters. After a series of conflicts associated with the truncation of the Apollo program, and facing severe budget constraints, von Braun retired from NASA on 26 May 1972. Not only had it become evident by this time that NASA and his visions for future U.S. space flight projects were incompatible, but also it was perhaps even more frustrating for him to see popular support for a continued presence of man in space wane dramatically once the goal to reach the Moon had been accomplished.
