Word Definition
atomic engine n. (1914) an engine powered by nuclear energy
atomics n. 1 (1932) any device powered by nuclear energy, esp. a nuclear-powered engine
grav n. 1 (1939) an anti-gravitational propulsion device; (typically as) gravs: a propulsion system using antigravity
gravity drive n. (1932) a spaceship drive that uses any technology associated with gravity
hyperdrive n. (1946) a spaceship drive that enables travel faster than the speed of light; (also) the state of such travel; cf. hyperspace n.
ion drive n. (1947) a spacecraft propulsion system that uses electrically accelerated ions
jet pack n. (1952) a device, worn over the shoulders like a backpack, which enables the wearer to travel through the air or in space by means of jet propulsion
jump drive n. (1959) a spacecraft drive that enables a ship to journey through hyperspace or to engage in any instantaneous (long-distance) travel; cf. jump n., jump v.
jump engine n. (1981) = jump drive n.
light sail n. (1963) = solar sail n.
overdrive n. (1945) = hyperdrive n.
ramscoop n. (1965) a space propulsion method that uses electromagnetic fields at the front of a spaceship to gather interstellar material for fuel for a fusion-powered space drive
reaction drive n. (1949) a propulsion system for a slower-than-light spacecraft that generates thrust by ejecting matter in a direction opposite that of travel
solar sail n. (1958) a surface designed to utilize the pressure of solar radiation to provide the propulsive force for a spacecraft to which it is attached
space drive n. (1932) a propulsion system for a spaceship; cf. star drive n.
space gun n. 1 (1929) a large gun which projects a spacecraft into space; (also) a hand-held gun whose recoil is used by an astronaut for propulsion
spindizzy n. (1950) in James Blish’s City in Flight series: a faster-than-light antigravity drive powered by a field that alters the magnetic rotation of atoms
star drive n. (1948) a propulsion device for a spaceship capable of interstellar travel, esp. one that permits the ship to travel faster than light; cf. earlier space drive n.
superluminal adj. (1959) having or being a speed greater than that of light; (also) designating an engine, etc., that can produce such a speed
torch n. (1950) = torch drive n.
torch v. (1956) to travel in a spaceship using a torch drive
torch drive n. (1976) a fusion-powered, slower-than-light space drive
torcher n. (1953) a pilot of a spaceship with a torch drive
torchship n. (1953) a spaceship that uses a torch drive n.
ultradrive n. (1951) a type of faster-than-light star drive
warp drive n. (1948) a device by which a spaceship is enabled to travel through space by means of a space warp; a faster-than-light drive
