Nuclear propulsion—a historical perspective

Abstract Those who fear development of nuclear propulsion for space travel forget that considerable work on it has already been done, starting in the 1950s, and that the concept of a nuclear rocket was safely and successfully tested in the 1960s. This article describes the history of the US Nuclear Engine for Rocket Vehicle Application programme, with technical details of its development. Although funding for the programme ceased in the 1970s, there is no reason to suppose that the concept would not work today.
