I am looking for the Terminal Countdown Demonstration Test (TCDT) dates for the following space shuttle missions:

STS-5, STS-6, STS-7, STS-8, STS-9, STS 41-B, STS 41-C, STS 41-D, STS 41-G, STS 51-A, STS 51-C, STS-51-D, STS 51-B, STS 51-G, STS 51-F, STS-51-I, STS 51-J, STS-61-A, STS 61-B, STS 61-C, STS 51-L, STS-26, STS-27, STS-29, STS-30, STS-28, STS-34, STS-33, STS-32, STS-36, STS-31, STS-41, STS-38, STS-35, STS-37, STS-39, STS-40, STS-43, STS-48, STS-44, STS-42, STS-45, STS-STS-46, STS-47, STS-52, STS-53, STS-54, STS-55, STS-58, STS-62, STS-68, STS-66, STS-71, STS-91, STS-96, STS-93, STS-103, STS-99, STS-101, STS-106, STS-97, STS-98, STS-102, STS-100, STS-104, STS-105, STS-108, STS-109 and STS-110.

These are when the astronauts are suited up and practice the countdown in the space shuttle cockpit/flight deck/mid deck. These occurred on the launch pads as well. Some space shuttle missions may of have had two TCDT due to launch scrubs/aborts and mission schedules changing?

Any information on TCDT would be very helpful. Thank you.

The dates of all those shuttle TCDTs can be found in the Space Shuttle Almanac that details all 135 shuttle missions in exhaustive detail.

That Space Shuttle Almanac I can highly recommend it! The owner is offering a bundle, including separate books for the Soviet / Russian, China, and ISS, each one is like 1000 pages and the whole bundle is a bargain at $10 US.

All times are CT (US)
