*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, launch preparations continue on schedule. Prelaunch oxidizer loading is complete and loading of fuel into Columbia's on-board storage tanks is in work. Cleaning of the gaseous nitrogen lines on the mobile launch platform continues through tomorrow. Today, workers will run cycling tests on the circuit breaker controller that supports Columbia's main engine No. 2. Technicians will resume external tank ordnance canister modifications in Columbia's aft compartment after hypergolic loading is complete. Early next week, orbiter aft compartment close-outs and ordnance installation will begin.

The STS-90 Flight Readiness Review is under way and NASA managers are expected to announce April 16 as Columbia's official launch date at the conclusion of the meeting.
