Drive amidst tall trees of Olympic Rain Forest. Heavy moss on trees and dense vegetation.
Atmospheric water resources experimentation near Olympia, Wasington. Technician lights lithium flare in tugboat near Washington coast on stormy day, in cloud seeding experiment. Flare falls over and makes a larger fire. Flares burn in small pot on rolling tugboat. Rough seas as seen from rolling tugboat coming into shore.
Washington High Mountain covered in snow. Dry bush in eastern Washington, located in rain shadow of Cascades.
Atmospheric water resources experimentation. Aircraft flies over Snoqualamie Pass. Technicians set off smoke flare on snow covered mountain. Trees on snow-covered mountains and plane flies overhead. Technician lights silver iodide generator on mountain during cloud seeding experiment.
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.)
Working of nuclear thermal rocket engine system in a NRX rocket, explained through animation. (The engine emerged from the NERVA program -- Nuclear Engine for Rocket Vehicle Applications -- a combined government and private industry (Aerojet and Westinghouse) effort headed by the Space Nuclear Propulsion Office (SNPO). Core of cylindrical nuclear reactor inside the rocket through which hydrogen gas passes. Hydrogen is expanded through the nozzle to provide thrust. Reactor works by fission of uranium 235. Neutron particles reflected back to the reactor. Rotating rods installed in reflectors around the reactor to control the heat generated. Reactors on test stand in testing area. Reactor transported on rail car. Scientists and technicians work with reactors in Atomic Energy Commission facility.
