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

      STS-91 images

      • 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
      • 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: With evaluations of the leaky fuel cell No. 3 relief valve complete, Shuttle engineers are recommending that no additional work or testing be performed on the valve preflight. The minor leak is well within acceptable limits and engineers are confident that in-flight water production will not be seriously impacted.

      AMS end-to-end testing began early this morning 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.

      STS-91 SCHEDULED OPERATIONAL MILESTONES (dates are target only):

      • SPACEHAB early stow (May 23)
      • Close payload bay doors for flight (May 26)
      • Orbiter aft compartment close-outs begin (May 26)
      • Ordnance installation complete (May 29)
      • Begin launch countdown (May 30 at 9 p.m.)
