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: Over the weekend, workers completed efforts to replace a failed electrical circuit breaker that supports Columbia's main engine No. 2. Late last Friday, managers decided to replace an integrated electronic assembly (IEA) in the aft of the left-hand solid rocket booster. The replaced IEA had transistors from the same manufacturing lot as those that had recently failed tests at KSC's SRB Assembly and Refurbishment Facility. The IEA replacement work was completed over the weekend and retests are slated for today. Technicians will complete efforts to reassemble the gaseous nitrogen panel on the mobile launch platform today and panel hydrocarbon sampling is in work. Orbiter aft compartment closeouts are in work and will conclude Saturday.
