In 1959 and 1960, he worked at the Langley Space Research Center in Hampton, Virginia. and later at NASA headquarters in Washington D.C.

As a space scientist, he helped organize the Mercury and Gemini crewed space flight programs in the late 1950s and 1960s. In the position of Project Director he headed the Apollo Lunar Landing Program^[2] producing the initial studies of the Apollo program, which resulted in the first crewed lunar landing in 1969. Later he was deputy director of the Skylab space station program. He also worked on the Space Shuttle program, including development of a manned maneuvering unit. His last position before retirement was "Director of Advanced Projects".

After retiring from NASA in 1980, he opened a consulting business under the name of "Avanti Systems". His clients included the Italian government, Aeritalia/MBB-ERNO, Boeing Aerospace, and the U.S. Office of Technology Assessment. From 1986 until his death in 1988 he served on the University of North Dakota School of Engineering and Mines Advisory Council.

His alma mater, the University of North Dakota, maintains a collection of John Disher papers ^[3] deposited by his widow.

In 1973 Disher received the NASA Distinguished Service Medal and twice he received the NASA Exceptional Service Medal, the latter in 1980 for his work on Skylab.
