In 1967, Mondale served on the Aeronautical and Space Sciences Committee, then chaired by Clinton P. Anderson, when astronauts Gus Grissom, Ed White, and Roger Chaffee were killed in a fire on January 27 while testing the Apollo 204 (later renumbered Apollo 1) spacecraft. NASA Administrator James E. Webb secured President Lyndon Johnson's approval for NASA to internally investigate the cause of the accident according to its established procedures, subject to Congressional oversight. NASA's procedure called for Deputy Administrator (and de facto general manager) Robert C. Seamans to appoint and oversee an investigative panel.
