MISSION: STS-91 -- 9TH AND FINAL MIR DOCKING, SPACEHAB-SM, Alpha Magnetic Spectrometer (AMS)

VEHICLE: Discovery/OV-103
LOCATION: Launch Pad 39A
KSC LAUNCH DATE/TIME: June 2 at about 6:10 p.m. EDT
LAUNCH WINDOW: 7-10 minutes
MIR DOCKING DATE/TIME: June 4 at about 12:59 p.m. EDT
MIR UNDOCKING DATE/TIME: June 8 at about 12:01 p.m. EDT
TARGET KSC LANDING DATE/TIME: June 12 at about 2:03 p.m. EDT
MISSION DURATION: about 9 days, 19 hours, 53 minutes
CREW: Precourt, Gorie, Lawrence, Chang-Diaz, Kavandi, Ryumin, Thomas (down)
ORBITAL ALTITUDE and INCLINATION: 173 nautical miles/51.6 degrees
NOTE: KSC workers have gained access to Discovery's aft compartment and will conduct standard main engine hydraulic testing today. Following yesterday's final inspection of the super lightweight external tank, the ice/debris inspection team noted no significant thermal protection system damage resulting from the recent tanking test. Engineering evaluations of the leaky fuel cell No. 3 relief valve are expected to conclude tomorrow. Though repairs on the valve are not expected to be necessary, as a precaution KSC engineers are developing a plan to reach the overboard valve from Discovery's midbody should access be required.

Electrical connections supporting the AMS payload are complete. The payload bay doors remain open as AMS end-to-end testing begins today and continues through Saturday. Payload bay camera testing is slated for this week and installation of the external tank separation camera is in work. The payload bay doors are scheduled to be closed on Tuesday.
