*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: At Pad 39B, prelaunch propellant load is complete. Columbia is currently powered down to allow workers to replace an electrical circuit breaker that supports main engine No. 2. The breaker failed during tests yesterday. Ordnance canister modifications in Columbia's aft compartment have resumed following successful hypergol loading efforts. Early next week, orbiter aft compartment close-outs and ordnance installation activities begin.

The STS-90 Flight Readiness Review concluded yesterday afternoon and NASA managers affirmed April 16 as Columbia's official launch date.
