NASAs Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen atop a mobile launcher at Launch Complex 39B, Sunday, April 3, 2022, as the Artemis I launch team conducts the wet dress practice session test at NASAs Kennedy Space Center in Florida. Ahead of NASAs Artemis I flight test, the wet gown practice session will run the Artemis I launch group through operations to fill propellant, perform a complete launch countdown, demonstrate the ability to recycle the countdown clock, and drain pipes the tanks to practice timelines and treatments for launch.

Teams have actually chosen to scrub tanking operations for the damp dress wedding rehearsal due to loss of capability to pressurize the mobile launcher. The fans are needed to supply positive pressure to the confined locations within the mobile launcher and keep out dangerous gases. Technicians are unable to safely proceed with loading the propellants into the rockets core phase and interim cryogenic propulsion phase without this capability.
Teams will now satisfy to determine next actions and establish a go forward strategy. The next opportunity to proceed into tanking is Monday, April 4. Teams will talk about variety and product schedule as part of the forward strategy.
