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: The STS-91 launch countdown begins tomorrow at 9 p.m. and all prelaunch preparations continue on schedule. The contingency space suits are installed in the orbiter's airlock. Aft main engine compartment close-outs continue with installation of the aft doors slated for tomorrow morning.

Preliminary weather forecasts indicate a 40 percent chance that weather could prohibit launch activities on Tuesday. The primary concern is for seabreeze thunderstorms with associated showers and anvil clouds. The forecast calls for scattered clouds at 4,000 feet and broken clouds at 30,000 feet; visibility of 7 miles (in thunderstorms possibly 2 miles); winds from the southeast at 12 knots peaking to 18 knots; a temperature of 83 degrees F and relative humidity of 63 percent.

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

Flight crew arrival (May 30 at 12:30 p.m.)
Begin launch countdown (May 30 at 9 p.m.)
Begin loading onboard cryogenic storage tanks (May 31 at 5 p.m.)
Retract Rotating Service Structure to launch position (June 2 at 12:30 a.m.)
Load external fuel tank with cryogenic propellants (June 2 from 9:14 a.m. to 12:14 p.m.)
