Starship

For the rocket, see SpaceX Starship. For other uses, see Starship (disambiguation).

An updated version (NASA, 1999) of the Project Orion by the United States government (1958-1965). It was the earliest scaled project developing a concept for a spaceship with a propulsion, of fission pulses, that was to be capable to transport humans light years within hundreds of years instead of thousands.

A starship, starcraft, or interstellar spacecraft is a theoretical spacecraft designed for traveling between planetary systems. The term is mostly found in science fiction. Reference to a "star-ship" appears as early as 1882 in Oahspe: A New Bible.

While NASA's Voyager and Pioneer probes have traveled into local interstellar space, the purpose of these uncrewed craft was specifically interplanetary, and they are not predicted to reach another star system; Voyager 1 probe and Gliese 445 will pass one another within 1.6 light years in about 40,000 years. Several preliminary designs for starships have been undertaken through exploratory engineering, using feasibility studies with modern technology or technology thought likely to be available in the near future.

In April 2016, scientists announced Breakthrough Starshot, a Breakthrough Initiatives program, to develop a proof-of-concept fleet of small centimeter-sized light sail spacecraft named StarChip, capable of making the journey to Alpha Centauri, the nearest star system, at speeds of 20% and 15% of the speed of light, taking between 20 and 30 years to reach the star system, respectively, and about 4 years to notify Earth of a successful arrival.

Research

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 (1958–1965), mostly crewed interplanetary spacecraft
• Project Daedalus (1973–1978), uncrewed interstellar probe
• Project Longshot (1987–1988), uncrewed interstellar probe
• Project Icarus (2009–2014), uncrewed interstellar probe
• Hundred-Year Starship (2011), crewed interstellar craft

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

Examined in an October 1973 issue of 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 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.

Types

• Sleeper: Starships that place their occupants into Cryostasis or Temporal Stasis during a long trip. This includes cryonics-based systems that freeze passengers for the duration of the journey. This is a common trope in science fiction, with some notable examples including "To Sleep in a Sea of Stars" by Christopher Paolini and Edward Bellamy's "Looking Backward"
• Generation: Ships in which the destination would be reached by descendants of the original passengers. These ships would necessarily be self-sustaining and self-maintaining for possibly thousands of years. Notable examples of this in fiction are the Godspeed in Beth Revis' "Across the Universe" (and subsequent sequels), as well as the Vanguard from Robert A. Heinlein's "Orphans of the Sky"

• Relativistic: Ships that function by taking advantage of time dilation at close-to-light-speeds, so long trips will seem much shorter (but still take the same amount of time for outside observers).
• Frame shift: Ships that take advantage of the fact that certain dimensions are less "folded" than others, to allow shorter travel by shifting one's frame of reference into a higher, more flat dimension to cut down on travel time, such as in science fiction with inter-dimensional hyperspace. Generally this results in speeds close to (but importantly, not greater than) light speed.
• Faster-than-light (FTL): A ship that functions by reaching a destination faster than the speed of light. While according to the special theory of relativity, faster-than-light travel is impossible, drives like a warp drive or using a wormhole, that is in principle similar have been hypothesized.

Theoretical possibilities

The Alcubierre drive is a speculative warp drive conjectured by Mexican physicist Miguel Alcubierre in a 1994 paper which has not been peer-reviewed. The paper suggests that space itself could be topographically warped to create a local region of spacetime wherein the region ahead of the "warp bubble" is compressed, allowed to resume normalcy within the bubble, and then rapidly expanded behind the bubble creating an effect that results in apparent FTL travel, all in a manner consistent with the Einstein field equations of general relativity and without the introduction of wormholes. However, the actual construction of such a drive would face other serious theoretical difficulties.

There are widely known vessels in various science fiction franchises. The most prominent cultural use and one of the earliest common uses of the term starship was in Star Trek: The Original Series.
