Thrust concepts

Specific proposals and research projects

• The Enzmann starship proposed in 1964 is a large fusion-powered spacecraft that could function as an interstellar ark, supporting a crew of 200 with extra space for expansion, on multi-year journeys at subluminal speeds to nearby star systems.
• In 1955 Project Orion considered nuclear propulsion for spacecraft, suitable for deep space voyages.
• In 1973–1978 Project Daedalus was conducted by the British Interplanetary Society to study unmanned interstellar spacecraft.
