The STS-26 launch of space shuttle Discovery begins the first flight to be flown after the Challenger accident. The flight crew included astronauts Rick Hauck, commander; Dick Covey, pilot; and three mission specialists, Dave Hilmers, Mike Lounge, and George (Pinky) Nelson. During the four-day mission, the crew deployed the Tracking and Data Relay Satellite (TDRS-C) and operated eleven mid-deck experiments. Discovery completed 64 orbits of the earth before landing at Edwards Air Force Base, California, on October 3, 1988. Photo credit: NASA or National Aeronautics and Space Administration
