NASA’s Artemis 1 moon mission attained an important preflight milestone on June 20th, finishing up a two-day series of tests called the wet dress rehearsal.

Those trials included fueling Artemis 1’s enormous Space Launch System (SLS) rocket and conducting a simulated countdown that put up the vehicle and NASA’s Orion capsule through most of the courses they would endure on launch day before the engine ignition. The fake countdown attained its conclusion at 7:37 p.m. EDT (2337 GMT), bringing a stop to the wet dress.

However, Not everything went flawlessly. The Artemis 1 team noted a hydrogen leak during fueling that day, and they deliberately “masked” data correlated with the issue to allow the countdown to continue. Similar data would have carried the red flags during an actual launch countdown, NASA officials said. This change implied that the countdown was halted at T-29 seconds before “liftoff” instead of T-9 seconds as initially scheduled.
“It’s a great day for our team,” Charlie Blackwell-Thompson, Artemis launch director with the Exploration Ground Systems Program at NASA’s Kennedy Space Center (KSC) in Florida, announced during a webcast of the wet dress barely after it wrapped up. “Really proud of them working through the loading operations and working through terminal count.”

Ground teams at KSC will spend the following few days preparing the Artemis 1 stack and mobile launch platform (MLP) for transport from Launch Pad 39B to the Vehicle Assembly Building (VAB), where technicians will analyze outcomes from these set of trials.
