Seals of National Aeronautics and Space Administration and Atomic Energy Commission indicate joint sponsorship of the idea in this film: namely, to promote consideration of Nuclear-powered rockets, in lieu of chemical-povered ones, in the U.S. Space Programs. Moon as seen from earth. Animation of a landing vehicle landing on surface of the moon. Animation of space vehicles and equipment in outer space and on a planet. Chemical Rockets are mentioned and are compared to future plans for Nuclear rockets to expand programs in space. View of Saturn V rocket on launch pad. Night time launch of Saturn V rocket from launch pad powered by chemical fuel. S-aturn V rocket ascending. View from rocket as part of propulsion system is ejected during ascent second stage. Animation and discussion of use of a nuclear powered third stage for propulsion. Animation of a lunar base and a spacecraft involved in a lunar supply mission. It is explained by animation how more thrust and efficiency is gained by use of nuclear rockets versus chemical rockets. (The program was the Nuclear Engine for Rocket Vehicle Application or NERVA, a nuclear thermal rocket engine development program.)
Testing of flight engines of spacecraft. Sign of 'PHOEBUS IB' nuclear reactor. Phoebus IB reactor in testing area of Atomic Energy Commission facility at Los Alamos in New Mexico. Technicians work with NRX-A6 reactor. A recently developed new test stand and a nuclear engine carried by rail car. Test of engines in test area. Animation shows spacecraft in space.
