Research
To travel between stars in a reasonable time using rocket-like technology requires very high effective exhaust velocity exhaust 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 (1958–1965), mostly manned interplanetary spacecraft
- Project Daedalus (1973–1978), unmanned interstellar probe
- Project Longshot (1987–1988), unmanned interstellar probe
- Project Icarus (2009–2014), unmanned interstellar probe
- Hundred-Year Starship (2011), manned interstellar craft
- See interstellar probes, interstellar travel
The Bussard ramjet is an idea to use nuclear fusion of interstellar gas to provide propulsion.
Other ideas involve going more slowly and building a generation ship, or trying to exceed the speed of light in some way, such as creating and maintaining a wormhole.
Examined in an October 1973 issue of Analog, the Enzmann Starship proposed using a 12,000 ton ball of frozen deuterium to power thermonuclear powered pulse propulsion units. Twice as long as the Empire State Building and assembled in-orbit, the spacecraft was part of a larger project preceded by interstellar probes 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.

Famous quotes containing the word research:
“The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?”
—Ron Taffel (20th century)
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?” [Was will das Weib?]”
—Sigmund Freud (1856–1939)
“It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.”
—Konrad Lorenz (1903–1989)
