Space shuttle Endeavour’s six astronauts arrived at NASA Kennedy Space Center’s Shuttle Landing Facility in four T-38 jets between 5:07 p.m. and 5:24 p.m. EDT. The crew is at Kennedy for their week-long launch dress rehearsal, called the Terminal Countdown Demonstration Test, or TCDT. TCDT will provide Endeavour’s astronauts and ground crews with an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training.

Later today STS-134 Commander Mark Kelly and Pilot Greg H. Johnson will practice shuttle landings in shuttle training aircraft. The next media event will be a Q and A at Launch Pad 39A on March 31 at 8:40 am. EDT The event will be aired on NASA TV. Launch of Endeavour on the STS-134 mission to the International Space Station is targeted for 7:48 p.m. EDT April 19. During the 14-day mission, Endeavour will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank, additional spare parts for Dextre and micrometeoroid debris shields.
