A crawler-transporter positions the mobile launcher platform supporting space shuttle Endeavour over the flame trench.

At NASA's Kennedy Space Center in Florida, a crawler-transporter positions the mobile launcher platform supporting space shuttle Endeavour over the flame trench on Launch Pad 39A. First motion on the 3.4-mile trip from the Vehicle Assembly Building, known as rollout, was at 4:13 a.m. EST Jan. 6. Endeavour was secure or "hard down" on the pad at 10:37 a.m.

Rollout is a significant milestone in launch processing activities. The primary payload for the STS-130 mission is the International Space Station's Node 3, Tranquility, a pressurized module that will provide room for many of the station's life support systems. Attached to one end of Tranquility is a cupola, a unique work area with six windows on its sides and one on top. The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. Endeavour's STS-130 launch is targeted for 4:39 a.m. EST Feb. 7.
