Space Shuttle Endeavour start backing through the gate to Launch Pad 39B after a cleat was discovered on the transporter.

Space Shuttle Endeavour and the Mobile Launcher Platform (MLP) start backing through the gate to Launch Pad 39B after a cracked cleat was discovered on the crawler-transporter. Workers near the pad (behind the crawler track) look at the cleats. The vehicle, which moves the MLP and Shuttle at about 1 mph, has a leveling system designed to keep the top of the Space Shuttle vertical while negotiating the 5 percent grade leading to the top of the pad. When the Shuttle-MLP are back on level ground, the crawler tracks will be inspected and the broken cleat repaired. Endeavour is scheduled to be launched Nov. 30 at 10:01 p.m. EST on mission STS-97, the sixth construction flight to the International Space Station. Its payload includes the P6 Integrated Truss Structure and a photovoltaic (PV) module, with giant solar arrays that will provide power to the Station. The mission includes two spacewalks to complete the solar array connections
