To travel between stars in a reasonable time using [[rocket]]-like technology requires very high [[effective exhaust velocity]] jet and enormous energy to power this, such as might be provided by [[fusion power]] or [[antimatter]].

There are very few scientific studies that investigate the issues in building a starship. Some examples of this include:

*[[Project Orion (nuclear propulsion)|Project Orion]] (1958–1965), mostly crewed interplanetary spacecraft
*[[Project Daedalus]] (1973–1978), uncrewed interstellar probe
*[[Project Longshot]] (1987–1988), uncrewed interstellar probe
*[[Project Icarus (Interstellar Probe Design Study)|Project Icarus]] (2009–2014), uncrewed interstellar probe
*[[Hundred-Year Starship]] (2011), crewed interstellar craft<!--DARPA study-->

The [[Bussard ramjet]] is an idea to use nuclear fusion of [[interstellar gas]] to provide propulsion.

Examined in an October 1973 issue of ''[[Analog Science Fiction and Fact|Analog]]'', the [[Enzmann Starship]] proposed using a 12,000-ton ball of frozen [[deuterium]] to power pulse propulsion units. Twice as long as the [[Empire State Building]] is tall and assembled in-orbit, the proposed spacecraft would be part of a larger project preceded by [[interstellar probe]]s and telescopic observation of target star systems.

The NASA [[Breakthrough Propulsion Physics Program]] (1996–2002) was a professional scientific study examining advanced [[spacecraft propulsion]] systems.
