On October 31, NASA’s Jet Propulsion Laboratory in Pasadena, Calif., celebrated its 76th anniversary. It began with a few individuals working on the Caltech campus and testing rocket motors in the Arroyo Seco. By the time this 1944 map of “The Project” was created, JPL was supported by Army Air Corps contracts and the site included more than 50 offices, labs and test facilities.
