Before the liftoff, the launch team and astronauts will perform a full launch dress rehearsal from February 21st to the 23rd. This will give everyone involved an opportunity to test out their contingency plans and emergency readiness.
Once Atlantis does launch on the 15th, the crew will help install the new truss segment, retract an old set of solar arrays, and unfurl the the new, larger starboard arrays on the station.
