NOTE: Atlantis is scheduled to land at KSC on the first of two opportunities tomorrow. KSC landing times are at 7:47 a.m. and 9:23 a.m. Two opportunities for landing are also available at Edwards Air Force Base, CA; however, no additional KSC landing support is being sent there today.

Tomorrow's weather at KSC shows the possibility of scattered low clouds at 4,000 feet and broken at 25,000 feet. For the first opportunity there is also a forecast for possible fog. Winds are expected to be from the east at 6 - 10 knots.

The crew of STS-81 are: Commander Michael Baker, Pilot Brent Jett, and Mission Specialists Jeff Wisoff, John Grunsfeld, Marsha Ivins, Jerry Linenger (up), and John Blaha (down).

• VEHICLE: Discovery/OV-103
• LOCATION: Pad 39A
• TARGET LAUNCH DATE/TIME: February 11 at 3:56 a.m.
• LAUNCH WINDOW: 65 minutes
• TARGET KSC LANDING DATE/TIME: February 21 at about 2:30 a.m.
• MISSION DURATION: 9 days, 22 hours
• CREW: Bowersox, Horowitz, Lee, Hawley, Harbaugh, Smith, Tanner
• ORBITAL ALTITUDE and INCLINATION: 360 statute miles/28.45 degrees

NOTE: Discovery arrived at Pad 39A late Friday afternoon and was hard down at about 5:05 p.m. Rollout was delayed about four hours when observers found a 24 foot-long crack on the Mobile Launcher Platform (MLP) surface. Engineering analysis indicated that there were no concerns for the weight bearing structure of the MLP and the Shuttle was cleared to resume rollout to the pad. Additional measurements taken at the pad indicate the MLP is structurally sound. Repairs to the surface are currently underway and should be complete by the end of the week.

The crew of mission STS-82 arrived yesterday for the scheduled Terminal Countdown Demonstration Test (TCDT) being held this week at KSC. Tomorrow, the countdown clocks will begin ticking for a simulated main engine ignition and cut-off Thursday morning. The crew will be aboard the orbiter Discovery through the simulated launch day events on Thursday.
