MISSION: STS-83 -- Microgravity Science Laboratory-1

VEHICLE: Columbia/OV-102
LOCATION: Pad 39A
TARGET LAUNCH DATE/TIME: April 3 at 2:01 p.m. EST
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: April 19 at about 7:37 a.m. EDT
MISSION DURATION: 15 days, 16 hours, 36 minutes
CREW: Halsell, Still, Voss, Thomas, Gernhardt, Linteris, Crouch
ORBITAL ALTITUDE and INCLINATION: 160 nautical miles/28.45 degrees

NOTE: The STS-83 Terminal Countdown Demonstration Test (TCDT) is underway today at KSC. The TCDT is held prior to each Space Shuttle flight providing the crew of each mission opportunities to participate in simulated countdown activities at KSC. The TCDT includes a mock launch countdown culminating in a simulated main engine cutoff (Friday). The crew also spends time undergoing emergency egress training exercises at the pad and has an opportunity to view and inspect their mission payloads in the orbiter's payload bay.

Overnight, inspections were made of the low pressure fuel turbo pumps on the three Space Shuttle main engines. The pump on engine No. 1 was found to have unacceptable rotor blades and the decision was made to remove and replace this pump. The work will begin today and is not expected to impact the overall schedule for launch. The engine heat shields are being removed at this time and the actual removal and replacement of the pump will take place tomorrow. A preliminary leak check will be conducted tomorrow night prior to previously scheduled pad operations on Saturday.
