Kathryn D. Sullivan, Ph.D., the first U.S. woman to do a spacewalk, designed this medallion to represent her astronaut career. The medallion marks her three space shuttle missions on Challenger, Discovery, and Atlantis and her roles as scientist, astronaut, and explorer. Dr. Sullivan made history as one of the first female astronauts and by doing an extravehicular activity, or EVA, during the STS 41-G shuttle mission in October 1984. She served in NASA from 1978 until 1993 and then moved on to a variety of other positions in government and education. In a nod to the military tradition of exchanging "challenge coins," Dr. Sullivan presented this medallion to the Museum when she delivered its 2015 John H. Glenn Lecture in Space History.
