(09/12/2000) -- A long view of Launch Complex 39 is caught by the early morning sun. Left of center is Launch Pad 39A with Space Shuttle Discovery. At its left is the 300,000-gallon water tank that is part of the sound suppression system. Hoses from the tank can be seen coiling under the pad, next to the opening of the flame trench, part of the flame detector system. In the foreground is a retention pond; another is at right center. At far right, the ball-shaped structure is a 850,000-gallon storage tank for the cryogenic liquid hydrogen, one of the propellants of the orbiter’s main engines. On the horizon can be seen the 525-foot tall Vehicle Assembly Building
