Former astronaut Eugene Cernan is donating his personal papers to Purdue's flight archives.
Cernan is a 1956 Purdue graduate and the most recent person to walk on the moon.
He became an astronaut in 1963 and went into space three times. As commander of Apollo 17 in 1972, he became the last to walk on the moon's surface.
The Purdue collection also includes the papers of Neil Armstrong, who in 1969 became the first to walk on the moon, and Amelia Earhart, the first woman to fly across the Atlantic Ocean and a Purdue staff member in the 1930s.
