On 9 September 2006, all the engine cut-off sensors were working properly, and following a flawless countdown, at 15:15 UTC (11:15 EDT), Atlantis lifted off the launch pad to the International Space Station.
As Atlantis launched, the International Space Station was 350 kilometres (220 mi) (220 mi) above the northern Atlantic Ocean, between Greenland and Iceland.

During the climb to orbit, Mission Control asked the crew to reconfigure a cooling system that apparently had ice build up.
The reconfiguration cleared the system, called the Flash Evaporator System, and it operated normally.
Temporary ice in that cooling unit is not uncommon and has occurred on previous missions.

Moments after main engine cutoff, 8.5 minutes after liftoff, Tanner and MacLean used hand-held video and digital still cameras to document the external tank after it separated from the shuttle.
That imagery, as well as imagery gathered by cameras in the shuttle's umbilical well where the tank was connected, was transmitted to the ground for review.
