Water flowed during a test at Launch Complex 39B at NASA’s Kennedy Space Center in Florida. About 450,000 gallons of water flowed at high speed from a holding tank through new and modified piping and valves, the flame trench, flame deflector nozzles and mobile launcher interface risers during a wet flow test at Launch Complex 39B. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was a milestone to confirm and baseline the performance of the Ignition Overpressure/Sound Suppression system. During launch of NASA's Space Launch System rocket and Orion spacecraft, the high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff.




The mobile service tower, or gantry, at Space Launch Complex 40 on Cape Canaveral Air Force Station falls to the ground after the base was demolished. The tall lightning towers around it will remain. This mammoth structure, with its cavernous clean room, was used for the final spacecraft launch preparations for NASA's Cassini spacecraft, currently orbiting Saturn. The launch occurred on Oct. 15, 1997, aboard an Air Force Titan IV-Centaur rocket. The facilities at the pad are being dismantled to make room for the construction of launch pad access and servicing facilities for the new Falcon rockets to be launched by Space Exploration Technologies, known as SpaceX.
