Endeavour crewmembers were awakened about 2:30 a.m. for a second day of landing opportunities. The song played for the crew was "Sojourner" by Matt Gast, the flight's lead timeliner or scheduler of crew activities.
Rain and thundershowers in the area of the Kennedy Space Center landing site in Florida caused flight controllers to wave off both of Monday's opportunities to bring Endeavour home.
Endeavour crewmembers, Commander Ken Cockrell, Pilot Paul Lockhart, and Mission Specialists Philippe Perrin and Franklin Chang-Diaz, and Expedition 4's Yury Onufrienko, Carl Walz and Dan Bursch, have two landing opportunities at KSC today. The first begins with the firing of Endeavour's braking rockets at 9:47 a.m. and a landing at 10:55 a.m. CDT. A second opportunity for a Florida landing would see the deorbit burn at 11:24 a.m. and a landing at KSC at 12:31 p.m. CDT.
The Edwards Air Force Base landing site in California will be activated today, though KSC remains the preferred landing location. The first of two opportunities to land at Edwards would see a deorbit burn at 12:54 p.m. and a landing at 2:02 p.m. CDT. For the second opportunity, the deorbit burn would begin at 2:32 p.m. with a landing at 3:38 p.m. CDT.
Preliminary forecasts for both KSC and Edwards call for a chance of showers and thunderstorms in Florida and gusty winds in California that could prevent a Tuesday landing. Endeavour has enough consumables on board to remain in orbit until Thursday.
Endeavour's crew completed all major objectives of its STS-111 flight. It rotated station crews, brought more than 9,000 pounds of equipment and supplies to the station, and in three successful spacewalks gave the station's robotic arm, Canadarm2, a mobile base for future station assembly and maintenance work, and replaced its wrist-roll joint.
Meanwhile, the ISS Expedition 5 crew - Commander Valery Korzun and Flight Engineers Peggy Whitson and Sergei Treschev - is still unpacking the supplies and equipment delivered by Endeavour to the station and familiarizing themselves with their new home.
The next STS-111 status report will be issued after landing or as events warrant.
