Is there an antimatter rocket in your future?
Propelling spaceships with antimatter may be closer to reality than you think.
Star Trek fans rejoice. Antimatter — the stuff that drives Captain Kirk's USS Enterprise in the 23rd century — is moving a step closer to spaceflight reality.
Antimatter holds an obvious appeal for rocket scientists. The mutual annihilation of matter with the same mass of antimatter offers the highest energy density known. Just 100 milligrams of antimatter contains the energy expended in a single space-shuttle launch.
