MISSION: STS-90 -- NEUROLAB

VEHICLE: Columbia/OV-102
LOCATION: Pad 39B
TARGET KSC LAUNCH DATE/TIME: April 16, 1998 at 2:19 p.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
*TARGET KSC LANDING DATE/TIME: May 3 at 11:07 a.m. EDT
*EXPECTED 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
*The mission is currently baselined to last 16 days (MET of 15/21:50). The option to add the 17th day, (MET of 16/21:48) if power margins permit, will be addressed during the flight.
NOTE: Launch preparations for STS-90 continue on schedule. Flushing of the gaseous nitrogen system lines on the mobile launch platform at Pad 39B concludes today. Loading of prelaunch propellants into Columbia's on-board storage tanks begins tomorrow. Early next week, orbiter aft compartment close-outs and ordnance installation will begin.

The STS-90 flight crew will conclude their mission familiarization activities at KSC today following a dress rehearsal of a simulated main engine cut-off at the launch pad. They are slated to return to their homes in Houston, TX later this afternoon.

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

Prelaunch propellant load (April 1)
Flight Readiness Review (April 2)
Orbiter aft compartment closeouts begin (April 6)
Ordance installation (April 7)

MISSION: STS-91 -- 9TH AND FINAL MIR DOCKING, SPACEHAB-SM

VEHICLE: Discovery/OV-103
LOCATION: OPF bay 2
TARGET KSC LAUNCH DATE/TIME: May 28 at 8:05 p.m. EDT
LAUNCH WINDOW: 7-10 minutes
TARGET KSC LANDING DATE/TIME: June 7 at about 3:36 p.m. EDT
MISSION DURATION: 9 days, 18 hours, 31 minutes
CREW: Precourt, Gorie, Lawrence, Chang-Diaz, Kavandi, Ryumin, Thomas (down)
ORBITAL ALTITUDE and INCLINATION: 173 nautical miles/51.6 degrees
NOTE: Auxiliary power unit lubrication servicing and orbiter docking system passive docking checks are complete. Payload premate testing is in work through tomorrow and preparations for main engine installation on Thursday are in work. Tunnel adapter installation is in work today.

External tank and solid rocket booster mating activities will resume tomorrow with no impact expected to Discovery's target launch date. Yesterday, NASA managers discussed the issue of a location marker magnet that was reported missing from the right forward center segment of the STS-91 booster stack last week. Based on thorough inspections and monitoring during stacking operations, KSC officials are confident that the 3/4" wide x 2" long magnet did not fall into the center joint that connects the booster's forward and aft segments.

Shuttle program managers from Johnson Space Center and Marshall Space Flight Center have determined, after considering all possible scenarios, that even if the magnet were inside the center joint the safety of the flight would not be compromised.

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

ET/SRB mate (April 1)
Shuttle main engine installation begins (April 2)
Crew Equipment Interface Test (April 4)

MISSION: STS-88 -- FIRST FLIGHT INTERNATIONAL SPACE STATION
(NODE-1, PMAs 1 and 2)

VEHICLE: Endeavour/OV-105
LOCATION: OPF bay 1
TARGET KSC LAUNCH DATE/TIME: July 9, 1998, at 12:44 p.m. EDT (under review)

NOTE: Torque checks of Endeavour's right wing-to-fuselage attach bolts are in work. Draining of the right-hand orbiter maneuvering system fuel cross-feed lines is in work. Technicians will complete forward reaction control system (FRCS) removal on Wednesday and then begin work to replace a leaky thruster in the Hypergol Maintenance Facility. With installation of the manipulator positioning mechanism complete this week, technicians will install the robot arm next Thursday.

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

Remove right-hand orbital maneuvering system pod (April 2)
Forward reaction control system removal (April 8)
Remote manipulator system installed (April 9)
