Find out more about the STS-105 Mission and Crew.

The Countdown Clock is one of the most watched timepieces in the world, and this Live Countdown Coverage page is the only place online to get up-to-the-minute information during a countdown. During the last 9/10 hours prior to scheduled liftoff, you can follow the exact chronology of each and every major event leading up to the successful countdown and liftoff of the Space Shuttle.

Check out our video coverage! It began with prelaunch videos prior to launch day, and will continue through liftoff and post-launch coverage. Follow the Real Media Movie Camera icon in the Video column below to your choice of a low bandwidth (28.8K), medium bandwidth (56K), or high bandwidth (cable/broadband) downloadable version.

Throughout this web site you will find several links to excerpts from the 1988 NSTS Shuttle Reference Manual. This manual has not been updated since it was originally published and contains some information that is now outdated. None of the thousands of Shuttle upgrades since that time -- like the Shuttle's new glass cockpit -- or organizational and managerial changes since then, are included. Even so, it is still -- by far -- the most comprehensive resource about the Space Shuttle program available online today.

Note: To follow along with the launch countdown, monitor the T-Time links in the left column below as they are activated. The event beginning and conclusion times shown below are projected timelines and subject to change at any time during actual launch countdown.

"T" stands for scheduled liftoff time, "-" stands for minus, "H" stands for hours,
"M" stands for minutes and "S" stands for seconds.

To review recent events that occurred earlier than the T-6 hour hold, go to the Previous Countdown Events Summary.
