Shuttle Endeavour ready for takeoff
The 11-day flight to the ISS will be the first for Endeavour in five years.
The crew mission is to upgrade the station and conduct three spacewalks.
New equipment will make it possible to receive power directly from the orbital station for the first time. That will allow shuttle crews to remain in orbit for longer.
Seven astronauts are assigned to the mission, but the spotlight is on a school-teacher, Barbara Morgan. During the lift she’ll be seated on the lower deck in the middle, exactly where Christa McAuliffe sat 21 years ago.
Morgan trained 22 years ago as the backup to Challenger which exploded after liftoff in 1986.
