Water Flows at Launch Pad 39B for Deluge Test

A water deluge test was completed May 24, 2018 at Launch Pad 39B at NASA's Kennedy Space Center in Florida.
Water flowed during a deluge test at Launch Pad 39B at Kennedy Space Center.

About 450,000 gallons of water flow 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 on May 24, 2018, at Launch Pad 39B at NASA’s Kennedy Space Center in Florida. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was performed by Exploration Ground Systems to confirm 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.
