NASA astronaut Ron Garan
is leaving the agency.
Garan will work on a range of new entrepreneurial and humanitarian efforts.
"Ron will certainly be missed by the Astronaut Office," said Bob Behnken, NASA's chief astronaut. "I'll miss Ron both as a contributor to our office and as a classmate."
Garan, who joined the agency in 2000, is ending a 13-year NASA career that included more than 178 days in space and four spacewalks. Garan flew in space twice, first in 2008 as a space shuttle Discovery mission specialist on STS-124, and again in 2011 aboard the International Space Station as a flight engineer for Expeditions 27 and 28. Garan retired from the Air Force as a colonel in 2009 after 25 years of service. He has logged more than 5,000 flight hours in more than 30 aircraft types. He recently served within NASA's Open Government Initiative.
