KENNEDY SPACE CENTER, FLA. - NASA’s specially designed barge, Pegasus, is docked in the Launch Complex 39 Area Turn Basin with its cargo of the newly redesigned External Tank. The barge was towed from the Michoud Assembly Facility in New Orleans. The tank will be off-loaded and transported to the Vehicle Assembly Building, seen at left of the barge. 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. New processing activities resulting from re-design of the tank include inspection of the bipod heater and External Tank separation camera, which includes charging the camera batteries. The tank will be then prepared for mating to the Solid Rocket Boosters. When preparations are complete, the tank will be lifted from the checkout cell, moved across the transfer aisle and into High Bay 1, where it will be lowered and attached to the boosters, which are sitting on the Mobile Launch Platform. The tank is designated for the Return to Flight mission, STS-114, targeted for a launch opportunity beginning in May. The seven-member Discovery crew will fly to the International Space Station primarily to test and evaluate new procedures for flight safety, including Space Shuttle inspection and repair techniques.
