NASA calls it the “Ignition Overpressure Protection and Sound Suppression water deluge system” and it is truly a sight to behold.
In just over a minute the system releases roughly 450,000 gallons of water, sending it 100 feet into the air. The goal: reduce the extreme amount of heat and energy generated by a rocket launch.
This test was conducted Oct. 15 at Kennedy Space Center’s Launch Pad 39B in
Florida in preparation for Exploration Mission-1, which is set to launch in June 2020. It will be the first uncrewed flight of the Space Launch System, a huge rocket arrangement NASA has been working for over a decade, set to be the most powerful booster ever built.
