NASA successfully completed an Artemis II mobile launcher water deluge test on Tuesday (Oct. 24) at the Kennedy Space Center. Why is this important? Well, because 400,000 gallons of water will rush onto the pad during liftoff to help protect the Space Launch System (SLS) rocket.



This massive amount of water will also keep the Orion spacecraft, mobile launcher, and launch pad protected from any over-pressurization and dampen the extreme sound produced during ignition as well as liftoff. Artemis II will become the first crewed mission under Artemis and will test all the Orion spacecraft’s systems with astronauts aboard when it launches in November 2024.
