Starship

A starship is a type of still-theoretical vehicle designed for interstellar travel, as opposed to a vehicle designed for interplanetary or orbital spaceflight which is often referred to as a spacecraft.

The term is mostly found in science fiction, as humanity has not yet constructed such vehicles (while the Voyager and Pioneer probes have traveled into local interstellar space, they are not generally considered starships, mainly because they are unpowered and unmanned). However, exploratory engineering has been undertaken on several preliminary designs and feasibility studies for starships that could be built with modern technology or technology thought to be available in the near future. For examples of such studies, see Project Daedalus, Project Orion, and Project Longshot.
