S128-E-007282 (4 Sept. 2009) --- Onboard the International Space Station since July, astronaut Tim Kopra is pictured on the orbital outpost a little less than a week before his scheduled return to Earth. Earlier this week, Kopra changed roles from Expedition 20 flight engineer to STS-128 mission specialist. Kopra came up to the station with the STS-127 crew and participated in a spacewalk on July 18. He will return to Earth aboard the Discovery on a scheduled Sept. 10 landing.
