Inside the Launch Control Center at NASA’s Kennedy Space Center in Florida, the launch team continues to closely monitor the weather. The forecast remains at 30 percent chance of favorable conditions for liftoff at 11:26 a.m. EDT. Teams are not working any issues that would delay the launch of Atlantis on mission STS-135, the final flight of the Space Shuttle Program.
Earlier this morning at Launch Pad 39A, filling of Atlantis’ external fuel tank with 535,000 gallons of super-cold liquid hydrogen and liquid oxygen began on time at 2:01 a.m. and was completed slightly ahead of schedule at 4:58 a.m.
