ANTIPROTON-CATALYZED MICROFISSION/FUSION PROPULSION SYSTEMS FOR EXPLORATION OF THE OUTER SOLAR SYSTEM AND BEYOND

Production and trapping of small numbers of antiprotons for space applications are feasible, setting the stage for antiproton-catalyzed microfission/fusion (ACMF) reactions as a source of propulsive power. A spacecraft designed around an ACMF engine has been designed. Details, including Isp, thrust, structural features, power systems, radiation shields, ion drivers, payload and system masses, will be reviewed. Staging of the spacecraft in space, including requisite propulsion and trajectory parameters and scientific goals for aggressive (Isp=10,000 sec, thrust=150 kN, ΔV=100 km/sec) outer solar system and extraplanetary missions will be discussed.
