No, I am referring to the NERVA rocket engine, a nuclear reactor that shoots superheated hydrogen out the back. The program was so successful followng the Apollo era that Congress cancelled all funding as it would have made a very expensive Mars trip viable using even 1970's technology (shortens the trip from 6 months to 2 months).
