A study of the ignition of uranium-hydrogen pellets with antiproton-induced fission is presented. Numbers of antiprotons required for successful pellet ignition are discussed. The driver uses light ion beams for compression and storage rings for antiprotons. An experiment on subcritical antiproton fission is described. Propulsive thrust is derived from radiation developed in a wavelength-shifter external to the pellet, which then expands into a mechanical shell. Ionization and expansion of materials from the shell by this radiation have been studied, as well as effects of heating and mechanical stress, neutrons and radiation damage on the system. A prototypical spacecraft (ICAN II) has been designed using this thrust mechanism. Requisite thrust and specific impulse parameters are considered for three interplanetary missions using this spacecraft. {copyright} {ital 1996 American Institute of Physics.}
