This week at the Kennedy Space Center’s Launch Complex 39B in Florida, the pad’s Ignition Overpressure Protection and Sound Suppression water deluge system underwent two flow tests. At peak flow, the water reached about 100 feet in the air above the pad surface. The testing is part of Exploration Ground Systems’ preparation for the new Space Launch System rocket. Modifications were made to the pad after a previous wet flow test, increasing the performance of the system. During the launch of Exploration Mission-1 and subsequent missions, this water deluge system will release approximately 450,000 gallons of water across the mobile launcher and Flame Deflector to reduce the extreme heat and energy generated by the rocket during ignition and liftoff.
