Leak checks of Endeavour's crew module and external airlock are complete. Auxiliary power unit controller checks are also complete. Last Friday, Endeavour's payload bay doors were cycled and over the weekend the orbiter's midbody was cleaned. Today, technicians will close the orbiter's payload bay doors in preparation for rollout.
Closeouts continue in the forward and aft compartments.
Auxiliary power unit leak checks are in work this week, along with orbiter maneuvering system electrical verifications. Workers have begun planned powered down modifications on orbiter Atlantis. This week, work to upgrade the orbiter's mass memory units is under way. Technicians are also replacing window No. 7. Atlantis will resume powered work in mid-December.
