The test lasted only 30 seconds, causing about 450,000 gallons of water to be dumped on the components of the launch pad, which will withstand the most extreme stresses, including deck and flame deflectors. The water flow system can emit 1 million gallons of water in a minute, helping to suppress the noise and vibration generated by the SLS rocket.

Nick Moss, deputy project manager at the launch pad, explained in a statement: "The SLS will generate about 176 decibels when it takes off, which is much larger than a jet aircraft. The water generated by the flow will suppress the sound by reducing the number of decibels.

The Space Launch System (SLS) will be very powerful, but it is not fully ready for launch missions. NASA has been forced to postpone preparation dates several times, and these repeated delays have seriously threatened Artemis's mission schedule.

NASA is still planning to return to the moon by 2024. Tests like this show that some aspects of the forecast are reasonable, but whether NASA can meet the current government-mandated launch deadline is uncertain.

On September 13, 2019, the Moist Water Flow Test Project at Launch Station Pad 39B tested a sound suppression system for NASA's space launch system for the Artemis I mission. During the test, about 450,000 gallons of water were poured onto the deck of the Pad B flame deflector, the mobile launcher flame hole and the launcher. This is the first time that a ground-based emission sequence generator used on launch day has been used for sound suppression testing.
