A retirement ceremony was held yesterday at NASA Ames Research Center in honor of the Aviation Systems Division's own Bo Bobko. Col. Karol “Bo” Bobko (retired) is an alumnus of the first graduating class of the Air Force Academy and was the first graduate to become an Astronaut and fly in space. During his 19 years in the astronaut program, Bo logged more than 386 hours in space and flew on three shuttle missions. He served as pilot during the maiden voyage of shuttle Challenger aboard STS-6 in April 1983, as commander of shuttle Discovery aboard STS-51D in April 1985, and as commander during the maiden voyage of shuttle Atlantis aboard STS-51J in October 1985. Bo retired from NASA and the U.S. Air Force in 1988. In May 2011, Bo was inducted into the U.S. Astronaut Hall of Fame. This June, Bo retired from SAIC as Program Manager for the Aviation Systems Division's simulation labs, where he continued to offer his expertise on human space flight and inspire the next generation of explorers.
