the external fuel tank before the Discovery shuttle stack was in full launch configuration. With the completion of the Flight Readiness Review over November 28–29 (which evaluated all activities and elements necessary for the safe and successful performance of the shuttle during the mission, including the Orbiter itself, the payload and flight crew), Discovery was given her Certificate of Flight Readiness, the launch date was officially set to December 7, 2006, and the mission officially given the "Go" for launch. Mission timeline December 7 (Launch attempt 1) Following the completion of the pre-launch preparations, all eyes were on the Florida skies, due to a forecast low cloud ceiling for the night of the launch. The mission's seven astronauts were loaded into Discovery ready for the scheduled launch at 21:37 EST, with hopes high for a break in the clouds, but as the scheduled launch time approached it became apparent that the cloud would not break, and the launch attempt was scrubbed, with the next attempt scheduled for December 9, 2006. Prior to the initial attempt on December 7, NASA had determined that they would not attempt a launch on Friday because of a cold front moving in that eventually scrubbed Thursday's launch attempt. December 9 (Flight day 1 – Launch) Discovery lifted off successfully at 8:47 pm EST (01:47 UTC), lighting up the Florida's coastline. Weather conditions – in particular crosswinds at the launch and landing sites – continued to trend positively in the hours approaching the launch window Saturday night. The fueling process for Discovery's external tanks began at 12:46 EST (17:46 UTC) and was completed at approximately 15:45 EST (20:45 UTC). If a transatlantic abort landing (TAL) had been required during ascent, the shuttle had three possible landing sites: Zaragoza or Morón Air Base in Spain, or Istres, France. The launch was the third shuttle mission in five months, being preceded by STS-121 in July and STS-115 in September, and was the first night launch in four years since STS-113 and first night launch following the Columbia accident during STS-107. It is also the last time a shuttle launched from LC-39B. December 10 (Flight day 2) Flight day 2 began for the astronauts at 15:47 UTC. The first order of business for the day was a thorough inspection of the Shuttle. Using sensors and cameras attached to a fifty-foot boom, which was in turn connected to a fifty-foot
