External Tank

August 4, 2005
Handheld still image taken by Discovery's crew of the external fuel tank as it was jettisoned after launch on July 26 were transmitted to the ground early July 27. Initial analysis of the imagery shows a large piece of foam that separated from the tank during the Shuttle's ascent to orbit. The foam detached from an area of the tank called the Protuberance Air Load (PAL) Ramp. This debris also was identified during ascent from a live video camera mounted on the external tank. The television view indicated the debris did not impact Discovery. In this still image, the area of missing foam on the tank is indicated by a light spot near the upper edge of the tank just below the liquid oxygen feedline.
