INSIDE THE SPACE SHUTTLE FUEL TANK

This photograph shows an inside view of a liquid hydrogen tank for the Space Shuttle external tank. At 154-feet long and more than 27-feet in diameter, the ET is the largest component of the Space Shuttle, the structural backbone of the entire Shuttle system, and is the only part of the vehicle that is not reusable.
