Bobko was the first graduate of the U.S. Air Force Academy to travel in space and the first person to fly on a space shuttle on three different missions: STS-6, STS-51-D, STS-51-J.

STS-6 was the sixth NASA Space Shuttle mission and the maiden flight of the Space Shuttle Challenger. Launched from Kennedy Space Center on April 4, 1983, the mission deployed the first Tracking and Data Relay Satellite, TDRS-1, into orbit, before landing at Edwards Air Force Base on April 9, 1983. STS-6 was the first Space Shuttle mission during which a Extravehicular activity was conducted, and hence was the first in which the Extravehicular Mobility Unit (EMU) was used.
