    Events in space history for 01/20:
    • Jet Propulsion Lab proposes a modified Apollo flight to fly around Mars and return to Earth (1965).
    • Buzz Aldrin born 1930.
    • Navy Bureau of Steam Engineering was allocated $100,000 to contract for the development and purchase of 200-hp radial aircooled engines from the Lawrance Aero Engine Corp (1920).
    • Acting in response to a request from BuAer, the Navy Bureau of Engineering endorsed support for the National Bureau of Standards for the development of radio meteorographs. Later renamed radiosondes, these instruments were sent aloft on free balloons to measure pressure, temperature, and humidity of the upper atmosphere, and transmitted these data to ground stations for use in weather forecasting and flight planning (1936).
    • Robert T. Jones, NACA Langley aeronautical scientist, formulated sweptback-wing concept to overcome shockwave effects at critical Mach numbers, and verified it in wind-tunnel experiments in March 1945 prior to learning of parallel German work. It was subsequently checked by the wing-flow technique before the first NACA report was issued in June (1945).
    • ICBM Scientific Advisory Committee to the Air Force was transferred to the Office of the Secretary of Defense to assure common interchange of technical information on all missile programs (1956).
    • United States and United Kingdom signed formal agreement covering minitrack station at Winkfield, England (1961).
    • Under NASA contract, United Technology Corp. successfully completed ground tests of three 15,000-pound thrust segmented solid-propellent rockets. Each was made up of three 1,000-pound sections which were joined prior to firing.
    • NASA's Marshall Space Flight Center (MSFC) awarded contracts to North American Aviation and Ryan Aeronautical to develop paraglider recovery system for the Saturn booster, based upon concept developed by Francis M. Rogallo of NASA's Langley Research Center (1961).
    • Headline news in Moscow was detailed Tass announcement that Strelka, one of two female dogs recovered from orbiting Spacecraft II in August 1960, had given birth to six puppies in good health. Pravda had announced 3 weeks earlier that one of the satellite-passenger dogs had given birth (1961).
