NASA to Research Antimatter Rocket

Posted by timothy on from the skeptical-until-it-blows-me-up dept.

Fraser Cain writes "One of the dozen technologies selected by NASA's Institute for Advanced Concepts (NIAC) this year is Positronics Research's ideas for an antimatter rocket engine. Instead of 3100 kg of propellant on board Cassini, the spacecraft could get by with just 310 micrograms of electrons and positrons. Of course, making the antimatter can be expensive."

    According to the Wikipedia producing antimatter is quite expensive. They mention something of $25 billion per gram.
    That's around $7'750'000 for these 310 micrograms...
