NASA has determined the crew for space shuttle Discovery's STS-129 flight whose mission will be to deliver two experiment racks, parts, and two spare gyroscopes to the International Space Station. The mission will feature four spacewalks, and returns Canadian Space Agency astronaut and station crew member Robert Thirsk to Earth. This is slated to be the final space shuttle crew rotation flight to or from the space station.

Marine Col. Charlie Hobaugh will command the mission, which is targeted to launch in October 2009. Navy Capt. Barry Wilmore will serve as the pilot. Mission Specialists are Robert Satcher, Navy Capt. Michael Foreman, Marine Lt. Col. Randy Bresnik and Leland Melvin. Wilmore, Satcher and Bresnik will be making their first trips to space.
