The Launch of Space Shuttle Atlantis Was Delayed!

Dec. 6 - 7:45 p.m. EST
At Thursday evening's press conference, NASA mission managers announced that the launch of space shuttle Atlantis would be delayed for 48 hours.

Liftoff of mission STS-122 from NASA's Kennedy Space Center is now scheduled for Saturday, Dec. 8 at 3:43 p.m. EST according to LeRoy Cain, Mission Management Team chairman.

Weather officer Captain Chris Lovett said the weather conditions are slightly less favorable for Saturday's launch with a 40 percent chance of weather prohibiting launch.

Thursday's launch was scrubbed when two of four LH2 Engine Cutoff (ECO) sensors failed to respond appropriately during tanking, which is a Launch Commit Violation.
