IOPSS Wet Flow Test at Pad 39B

A flow test of the Ignition Overpressure Protection and Sound Suppression water deluge system is underway on the mobile launcher at Launch Pad 39B at NASA's Kennedy Space Center in Florida, on July 25, 2019. The testing is part of a series of tests that Exploration Ground System is doing to verify the system is ready 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 Artemis 1 and subsequent missions, this water deluge system will release about 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.
