NASA has published a video demonstrating the operation of a special system designed to suppress noise and jet emissions during the launch of rockets. The full name of the system in English sounds like Ignition Overpressure Protection and Sound Suppression water deluge system. A little more than a minute, she is able to throw out about 2 million liters of water.
The height of the water column reaches 30 meters. Fluid is needed to reduce noise and temperature when launching rockets. As noted by CNET, the volume of water discharged is enough to fill the Olympic pool.
Tests were held on October 15 in preparation for the mission to Mars in 2020.
