T-minus 4 minutes. Activation of the APUs is complete. The three units are up and running normally.
And the final helium purge sequence is underway in the main propulsion system. This procedure readies fuel system valves for engine start. In the next few seconds, the aerosurfaces of Atlantis will be run through a pre-planned mobility test to ensure readiness for launch.
