An antimatter rocket is a proposed class of rockets that use antimatter as their power source. There are several designs that attempt to accomplish this goal. The advantage to this class of rocket is that a large fraction of the rest mass of a matter/antimatter mixture may be converted to energy, allowing antimatter rockets to have a far higher energy density and specific impulse than any ...
Antimatter-catalyzed nuclear pulse propulsion (also antiproton-catalyzed nuclear pulse propulsion) is a variation of nuclear pulse propulsion based upon the injection of antimatter into a mass of nuclear fuel to initiate a nuclear chain reaction for propulsion when the fuel does not normally have a critical mass.
A nuclear pulse drive starship powered by fusion-antimatter catalyzed nuclear pulse propulsion units would be similarly in the 10% range and pure Matter-antimatter annihilation rockets would be theoretically capable of obtaining a velocity between 50% and 80% of the speed of light. In each case saving fuel for slowing down halves the maximum speed.
Isolated and stored antimatter could be used as a fuel for interplanetary or interstellar travel [88] as part of an antimatter-catalyzed nuclear pulse propulsion or another antimatter rocket. Since the energy density of antimatter is higher than that of conventional fuels, an antimatter-fueled spacecraft would have a higher thrust-to-weight ...
AIMStar, a proposed Antimatter-catalyzed nuclear pulse propulsion craft that uses clouds of antiprotons to initiate fission and fusion within fuel pellets; ICAN-II, a proposed crewed interplanetary spacecraft that used the antimatter-catalyzed nuclear pulse propulsion engine as its main form of propulsion
ICAN-II was a proposed crewed interplanetary spacecraft that used the antimatter-catalyzed micro-fission (ACMF) engine as its main form of propulsion. The spacecraft was designed at Penn State University in the 1990s as a way to accomplish a crewed mission to Mars.
NASA will partner with the U.S. military's research and development agency, DARPA, to develop a nuclear thermal propulsion engine and launch it to space "as soon as 2027," NASA administrator Bill ...
Niven also employed Bussard Ramjets as the propulsion / stabilizing engine of the Ringworld (four novels), which were also set in Known Space. In the Star Trek universe, a variation called the Bussard Hydrogen Collector or Bussard Ramscoop appears as part of the matter / antimatter propulsion system that allows Starfleet ships to travel faster ...
