Commemorating the 40th anniversary of Apollo 1
Purdue alumni have flown more than one-third of all manned U.S. flights, including Gus Grissom from Project Mercury in 1961; Neil Armstrong, Eugene Cernan and Grissom in the Gemini program in 1965 and 1966, and Armstrong and Cernan in the Apollo program from 1969–1972. Neil Armstrong and Eugene Cernan, respectively, were the first and last men to set foot on the moon.
