Proposal for a Concept Assessment of a Fission Fragment Rocket Engine (FFRE) Propelled Spacecraft

Completed Technology Project

Project Introduction

A new technology, the Fission Fragment Rocket Engine (FFRE), requires small amounts of readily available, energy dense, long lasting fuel, significant thrust at specific impulse of a million seconds, and increases safety by charging the reactor after arrival in LEO. If this study shows the FFRE potential, the return could be immense through savings in travel time, payload fraction, launch vehicle support and safety for deep space exploration.
