      Launch Viewing Information

      MISSION: STS-90 -- NEUROLAB

      STS-90 images

      • VEHICLE: Columbia/OV-102
      • LOCATION: OPF bay 3
      • TARGET KSC LAUNCH DATE/TIME: April 2, 1998 at 1:19 p.m. (under review)
      • LAUNCH WINDOW: 2 hours, 30 minutes
      • TARGET KSC LANDING DATE/TIME: April 19, l998 at 12:07 p.m.
      • MISSION DURATION: 16 days, 21 hours, 48 minutes
      • CREW: Searfoss, Altman, Linnehan, Williams, Hire, Buckey, Pawelczyk
      • ORBITAL ALTITUDE and INCLINATION: 150 nautical miles/39 degrees

      NOTE: Pressure decay checks of Columbia’s crew module and tunnel adapter are complete. Replacement of the bushings on the main engine heat shields is in work. Preparations are under way for a pressure test of the orbiter’s flash evaporator system on Friday. Aft compartment closeouts are ongoing, and main engine installation is slated for Friday.

      Technicians noted separated insulation on a piece of tubing in Columbia’s midbody. Closeouts of midbody bay 7 will be delayed one day while workers replace the insulation. As a result, the Neurolab payload is now scheduled for installation into the orbiter on Thursday rather than tomorrow.

      STS-90 SCHEDULED OPERATIONAL MILESTONES (dates are target only):

      • Payload installed into orbiter (Feb. 12)
      • Shuttle main engine installation complete (Feb. 13)
      MISSION: STS-91 -- 9TH MIR DOCKING & SPACEHAB-SM

      • VEHICLE: Discovery/OV-103
      • LOCATION: OPF bay 2
      • TARGET KSC LAUNCH DATE/TIME: May 28 at 8:05 p.m.
      • LAUNCH WINDOW: 7-10 minutes
      • TARGET KSC LANDING DATE/TIME: June 7 at about 3:36 p.m.
      • MISSION DURATION: 9 days, 19 hours, 31 minutes
      • CREW: Precourt, Gorie, Lawrence, Chang-Diaz, Kavandi, Ryumin, Thomas (down)
      • ORBITAL ALTITUDE and INCLINATION: 160 nautical miles/51.6 degrees

      NOTE: Replacement and cycling of the power drive unit for the right external tank umbilical door are complete. Body flap corrosion repair and super lightweight tank instrumentation modifications continue, and engine heat shield attach point assessments are in work. The Mir docking mechanism is being connected to Discovery’s external airlock, and the airlock will be installed into the orbiter on Feb. 13.

      The super lightweight external tank will be transferred to the checkout cell in Vehicle Assembly Building high bay 2 today. Once that transfer is complete, solid rocket booster stacking will begin for mission STS-91.

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

      • External airlock installation complete (Feb. 13)
      • Forward reaction control system installation complete (Feb. 16)
      • Right-hand orbiter maneuvering system pod installation complete (Feb. 20)
      MISSION: STS-88 (01-2A) ISS FIRST FLIGHT

      STS-88 images

      • VEHICLE: Endeavour/OV-105
      • LOCATION: OPF bay 1
      • TARGET KSC LAUNCH DATE/TIME: July 9, 1998, at 12:44 p.m.
      • TARGET KSC LANDING DATE/TIME: July 20, 1998 at 8:02 a.m.

      • ORBITAL ALTITUDE and INCLINATION: 170 nautical miles/51.6 degrees

      NOTE: Yesterday, the SPACEHAB payload was removed from Endeavour’s payload bay. Orbiter power systems validation is also complete. Main propulsion system and Shuttle main engine post-flight inspections continue, and orbiter maneuvering system cross-feed lines will be drained beginning tomorrow. Tunnel adapter removal is scheduled for Thursday.

      STS-88 SCHEDULED OPERATIONAL MILESTONES (dates are target only):

      • Tunnel adapter removal (Feb. 12)
      • Main engine heat shield removal (Feb. 26)
      • Main engine removal complete (Mar. 3)
