NASA KSC Shuttle Status Report
Orbiter Atlantis remains in OPF bay 3 today while technicians continue tile-drying efforts. It is expected that Atlantis will roll over to the Vehicle Assembly Building no earlier than Tuesday, May 29. As a result, the target launch date has been reset for no earlier than June 20.

In the OPF, engineers continue to evaluate orbiter Atlantis' thermal protection system while technicians use clusters of 200-300 watt heat lamps to dry or "bake" about 600 Shuttle tiles. The orbiter was exposed to significant rainfall while at Edwards Air Force Base, Calif., following its landing there in February, at the conclusion of mission STS-98.

At this time, the drying work is focused on the black tile located below the leading edge of the orbiter's right wing. Tile baking is also in work near the left-hand main landing gear door. Engineers are evaluating the current procedures to assure the tiles are in a safe and flight-ready condition. A wet tile can freeze in orbit and possibly debond or separate from the orbiter during reentry.
