STS006-46-667 (9 April 1983) --- One of the final pictures taken aboard the space shuttle Challenger is this 35mm frame of Landing Strip 22 at Edwards Air Force Base as the reusable spacecraft was lined up for its landing only seconds later. The frame was exposed by astronaut Donald H. Peterson, STS-6 mission specialist, who was stretching behind the commander’s seat occupied by astronaut Paul J. Weitz on the flight deck. Also onboard the spacecraft for the five-day flight were astronauts Karol J. Bobko, pilot, and Dr. F. Story Musgrave, mission specialist. Photo credit: NASA
