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 introduce team carries out the wet dress practice session test at NASAs Kennedy Space Center in Florida. Ahead of NASAs Artemis I flight test, the damp gown rehearsal will run the Artemis I launch team through operations to fill propellant, carry out a complete launch countdown, show the capability to recycle the countdown clock, and drain pipes the tanks to practice timelines and procedures for launch.

The countdown for the damp gown rehearsal has actually resumed at 10:52 a.m. EDT and clocks have chosen back up at T-6 hours, 40 minutes on the clock (L-7 hours, 10 minutes). A brand-new planned T-0 of 6:02 p.m. has actually been developed.
An earlier concern with a blackout with the supplier of gaseous nitrogen required for tanking preparations has actually been solved. Overnight, teams also resolved the issue with the malfunction of the fans used to supply positive pressure to confined locations in the mobile launcher and keep out hazardous gases, and they have a strategy for operating the fans to prevent issues from repeating. The team had the ability to successfully bring up and run the primary fan through the night to provide confidence, and has actually set up the secondary fan to perform at 80% capacity to support tanking operations.
At approximately 10 a.m. EDT, the launch director provided the “go” to begin tanking the rocket. Cryogenic filling operations are arranged to begin with cooling down the liquid oxygen lines for the core phase. When propellant loading operations start, liquid oxygen (LOX) and liquid hydrogen (LH2) will stream into the into the rockets core phase and interim cryogenic propulsion stage tanks and be topped off and replenished as some of cryogenic propellant boils off. The group will also perform leak checks to ensure propellant loading is proceeding as anticipated.

NASA is streaming live video of the rocket and spacecraft at the launch pad on the Kennedy Newsroom YouTube channel. Venting might show up during tanking operations. NASA is likewise sharing live updates on the Exploration Ground Systems Twitter account.
When core phase propellant loading is underway, the next blog site upgrade will be offered.
