Digital umbilical well image taken after Space Shuttle Discovery separated from its external fuel tank following its launch on July 26, 2005. The image reveals 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. The area of missing foam on the tank is indicated by a light spot centered just below the liquid oxygen feedline.
