Abbreviated TCDT at Kennedy

At NASA's Kennedy Space Center in Florida, space shuttle Atlantis' STS-129 mission astronauts will be traveling to Launch Pad 39A where they will practice emergency pad egress and other related safety training.

While at the pad, the crew will have a brief question-and-answer period with the media broadcast on NASA TV. The media event will begin at 9:40 a.m. EDT and can be accessed at

In order to optimize NASA's ability to launch both Atlantis and the Constellation Program's Ares I-X flight test before the end of the year, the agency now is targeting Nov. 16 for the launch of Atlantis' STS-129 mission to the International Space Station. Therefore, the crew will cut this Terminal Countdown Demonstration Test, or TCDT, short and conduct the remainder of launch dress rehearsal training Nov. 2 and 3.

The same launch team at Kennedy is supporting both the shuttle and the Ares I-X flight test, which is targeted to lift off Oct. 27.
