A live webcast featuring National Aeronautics and Space Administration astronaut Robert Satcher will start the in-depth coverage of the STS-122 mission at 11:30 a.m. EST Dec. 5.

A blog will update the countdown beginning about six hours before Atlantis is scheduled to lift off Dec. 6 at 4:31 p.m. EST. Originating from NASA's Kennedy Space Center, the blog will be the main Internet source for information leading up to launch.

During the 11-day mission, Atlantis' crew of seven astronauts will deliver the European Space Agency's new Columbus laboratory, setting the stage for expanding the space station's science capabilities.

NASA-TV will also provide coverage of the mission.
