At NASA's Kennedy Space Center in Florida, a sign points space shuttle Endeavour to Launch Pad 39A, in the background at left. First motion out of the Vehicle Assembly Building was at 4:13 a.m. EST Jan. 6. The 3.4-mile trip, known as rollout, takes about six hours.

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. Space shuttle Endeavour's STS-130 mission is targeted for launch at 4:39 a.m. EST Feb. 7.
