Space travel, [1]: 69 [2]: 209–210 [3]: 511–512 or space flight [2]: 200–201 [4] (less often, starfaring or star voyaging [2]: 217, 220 ) is a science fiction theme that has captivated the public and is almost archetypal for science fiction. [4] Space travel, interplanetary or interstellar, is usually performed in space ships, and ...
The Bussard ramjet is a theoretical method of spacecraft propulsion for interstellar travel.A fast moving spacecraft scoops up hydrogen from the interstellar medium using an enormous funnel-shaped magnetic field (ranging from kilometers to many thousands of kilometers in diameter); the hydrogen is compressed until thermonuclear fusion occurs, which provides thrust to counter the drag created ...
Many science fiction authors as well as depictions in popular culture showed rockets landing vertically, typically resting after landing on the space vehicle's fins. This view was sufficiently ingrained in popular culture that in 1993, following a successful low-altitude test flight of a prototype rocket, a writer opined: "The DC-X launched ...
Warp drive, or a drive enabling space warp, is one of several ways of travelling through space found in science fiction. [3] It has been often discussed as being conceptually similar to hyperspace. [3] [4]: 238–239 A warp drive is a device that distorts the shape of the space-time continuum.
Spaceships are often one of the key plot devices in science fiction. Numerous short stories and novels are built up around various ideas for spacecraft, and spacecraft have featured in many films and television series. Some hard science fiction books focus on the technical details of the craft.
An early appearance of an Orion-style nuclear pulse propelled rocket in science fiction was in the science fiction novel Empire of the Atom written by A. E. van Vogt in 1956. In this novel there is a post-atomic-war interplanetary empire called the Empire of Lynn that uses Orion-type nuclear rockets for interplanetary spaceflight.
The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant.A propellantless drive is not necessarily reactionless when it constitutes an open system interacting with external fields; but a reactionless drive is a particular case of a propellantless drive that is a closed system, presumably in contradiction with the law of conservation of momentum.
