KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
 
 
4:24 PM EDT

KSC Public Affairs Contact: Joel Wells (fax: 407-867-2692)

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
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.)

MISSION: STS-88 -- FIRST FLIGHT INTERNATIONAL SPACE STATION
NODE-1 (Unity)

VEHICLE: Endeavour/OV-105
LOCATION: OPF bay 1
TARGET KSC LAUNCH DATE/TIME: No earlier than Sept. 3 (under review)
MISSION DURATION: 10 days, 19 hours, 18 minutes
CREW: Cabana, Sturckow, Currie, Ross, Newman
ORBITAL ALTITUDE and INCLINATION: 173 nautical miles/51.6 degrees
NOTE: Technicians have completed auxiliary power unit drain line connections. Flushing of the ammonia boiler system is scheduled for today. In the Vehicle Assembly Building, solid rocket booster joint close-outs are in work and external tank/solid rocket booster mate is slated for the first week in June.

MISSION: STS-93 -- Advanced X-ray Astrophysics Facility (AXAF)

VEHICLE: Columbia/OV-102
LOCATION: OPF bay 3

Yesterday, workers removed the orbiter's payload recorder. Efforts to remove the extended duration orbiter (EDO) pallet continue through next week. Preparations for orbiter maneuvering system functional tests are in work.
