When President Dwight Eisenhower signed the National Aeronautics and Space Act in 1958, Charles "Pete" Conrad '53 was training as a U.S. Navy test pilot.

Nov. 19 marks the 50th anniversary of Conrad’s moonwalk, part of the Apollo 12 mission, and to mark the occasion, PAWcast spoke with Jordan Bimm, a historian of science and postdoc in Princeton’s sociology department.
