The newly redesigned External Tank slowly moves toward the Vehicle Assembly Building, seen at right. The tank arrived Jan. 5 after a 900-mile sea voyage aboard NASAs specially designed barge, Pegasus, from the Michoud Assembly Facility in New Orleans. In the transfer aisle of the VAB, the tank will be raised from a horizontal to a vertical position, then lifted high up into a storage cell, or checkout cell, where it will undergo inspections of the mechanical, electrical and thermal protection systems.
