Spiral-bound report entitled "Missions and Flight Operations for Nuclear Rockets (LMSC-A653019)," prepared by the Space Systems Division of the Lockheed Missiles & Space Company, 27 pages, 11 x 8.5, November 1964. The foreword reads: "This summary report on the missions and flight operations for nuclear rockets was originally presented at the 11th Nuclear Science Symposium in Philadelphia, Pa., 28-30 October 1964. The results presented reflect an interpretation of extensive studies of nuclear rocket applications." The nicely illustrated text discusses development flights, operational missions, advanced missions, and safety considerations. It concludes that "the nuclear rocket stands alone as the system offering the greatest gains in vehicle efficiency consistent with the current status of propulsion technology." In fine condition.
