Mission STS-122 is scheduled to launch at 4:31 p.m. EST from NASA's Florida launch base. Atlantis will carry the European-developed Columbus laboratory and attach it to the International Space Station. Seven astronauts, including two from the European Space Agency, will fly aboard Atlantis.
Technicians and engineers at the launch pad have several steps ahead of them Wednesday. The most visible milestone will come in the evening when the Rotating Service Structure is moved to its launch position where it will be out of the way of Atlantis. The gantry encloses much of the shuttle while it is on the launch pad and gives workers access to critical areas of the shuttle and its payload.
The weather forecast calls for a 90 percent chance of acceptable conditions at launch time.
"The vehicle's looking good and the weather's looking good, too," Shuttle Weather Officer Kathy Winters said.
