About This Tool

Rollbacks are the terminology used by NASA to roll the shuttle back from the mobile launch pad and the launch pad on top of the tracked Vehicle Assembly Building. If the aircraft is unable to launch due to bad weather or other reasons, many factors may need to roll back. Rollback times like this have occurred many times in history, and the tool only randomly selected 20 of them to introduce.

In the generator, we can see the exact beginning and end of the rollback times of these buses. It includes the detailed date of the rollback, the Orbiter, the tasks to be completed, the reason for the rollback, and the main description of the rollback at the time. In summary, rollback is most likely due to Inspection failure, Weather, Abort, Fuel leak, Payload, External tank repairs, and several other major causes affecting the actual time of launch.
