Remarks: Another bittersweet moment for the Space Transportation System (STS) program as 'Endeavour" departs high Bay #3 of the 525 foot tall Vehicle Assembly Building (VAB) for the last time. The top of the "stack" is approx 225 feet from ground. So this is a 22 story building traveling at 0.08 mph. The Mobile Launch Platform (MLP) for STS-135 can be seen in the crack of door of high bay #1. The lights are to illuminate the stack as she takes the 3.1 mile trek to pad 39A.
