Artemis II Water Deluge Test (Photo Release - October 24)

NASA’s Exploration Ground Systems conducts a water flow test with the mobile launcher at Kennedy Space Center’s Launch Complex 39B in Florida on October 24, 2023. It is the third in a series of tests to verify that the overpressure protection and sound suppression system is ready for launch of the Artemis II mission.

During liftoff, 400,000 gallons of water will rush onto the pad to help protect NASA’s SLS (Space Launch System) rocket, Orion spacecraft, mobile launcher and launch pad from any over pressurization and extreme sound produced during ignition and liftoff.

Yesterday, NASA conducted a full flow test of the Ignition Overpressure and Sound Suppression (IOPSS) system on Mobile Launcher 1. This test slowly ramped up the water flow levels in the same manor as they would during the launch of an SLS rocket.
