KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
 
 
1:02 PM EDT

MISSION: STS-93 -- Chandra X-ray Observatory

VEHICLE: Columbia/OV-102
LOCATION: Launch Pad 39B
TARGET KSC LAUNCH DATE/TIME: No earlier than July 20, 1999 at 12:36 a.m. EDT (under review)
TARGET KSC LANDING DATE/TIME: July 24, 1999 at 11:31 p.m. EDT
LAUNCH WINDOW: 46 minutes
MISSION DURATION: 4 days, 23 hours
CREW: Collins, Ashby, Hawley, Coleman, Tognini
ORBITAL ALTITUDE and INCLINATION: 153 nautical miles/28.45 degrees
NOTE: Yesterday, workers disabled the drive train for truck No. 1 on the Rotating Service Structure (RSS) at Launch Pad 39B to accommodate RSS rotation tests this morning. With those tests successfully completed, RSS operations will proceed normally using only truck No. 2 . If all continues to go well, the Chandra/IUS payload will arrive at Launch Pad 39B early Thursday morning for installation into the payload changeout room on the RSS. The payload will then be installed into Columbia's payload bay no earlier than Monday.

Last Monday night one of the two RSS trucks that extend and retract the RSS away from the Shuttle failed to operate properly. Because the RSS did not fully retract and stopped after moving only four inches, the Chandra/IUS payload was not transferred to the launch pad. The RSS must be retracted for a payload to be installed into the payload changeout room.

A hot fire test of auxiliary power unit No. 2 has been successfully completed. Terminal Countdown Demonstration Test activities continue, but Thursday's dress rehearsal will now start two hours late culminating with a simulated main engine cut-off at about 1 p.m. Columbia remains targeted for launch no earlier than July 20.

STS-93 SCHEDULED OPERATIONAL MILESTONES (dates are target only):

Chandra payload arrives at Pad 39B (NET June 24)
Terminal Countdown Demonstration Test complete (June 24)
Payload installed inside payload bay (NET June 28)
Flight Readiness Review (July 8)

MISSION: STS-99 -- SHUTTLE RADAR TOPOGRAPHY MISSION (SRTM)

VEHICLE: Endeavour/OV-105
LOCATION: OPF bay 2
TARGET KSC LAUNCH DATE/TIME: Sept. 16, 1999 at 8:47 a.m. EDT
