NOTE: Orbiter midbody umbilical unit mate and leak checks are complete. Endeavour's aft compartment close-outs continue through Saturday and ordnance installation is in work today. Work to replace a decoder on microwave scanning beam landing system No. 3 is ongoing and payload bay doors will be closed for flight on Friday. Hypergolic system closeouts begin tomorrow and continue through Saturday.

Shuttle engineers continue to evaluate the auxiliary power unit (APU) hydraulic lines that were serviced earlier this week. Assessments of APU No. 3 is complete. Workers today will evaluate the APU No. 1 hydraulic lines.

A replacement motion control computer and air conditioning unit for Russia's Mir Space Station will be installed into the SPACEHAB module Sunday. Fit checks of the air conditioning unit are in work and delivery of the computer is expected late Friday night.
