Atlantis Crew Rehearses Launch Countdown

‪The four-member crew of the final space shuttle mission participated in a full launch dress rehearsal, known as the Terminal Countdown Demonstration Test, on June 23 at NASA's Kennedy Space Center in Florida. The test provided an opportunity for the crew and ground teams to participate in various simulated countdown activities, including equipment familiarization, emergency training and a simulated launch countdown. Atlantis' crew members are Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandy Magnus and Rex Walheim. ‪During the 12-day STS-135 mission, Atlantis' astronauts will deliver to the International Space Station the Raffaello multi-purpose logistics module filled with supplies, logistics and spare parts that will sustain station operations once the shuttles are retired this summer. Atlantis' launch is targeted for July 8. This will be the final flight of the Space Shuttle Program.
