NASA plans to conduct a critical refueling test of the Artemis 1 space launch system, known as the "Wet Clothes Exercise," June 29.The Space Launch System (SLS) will make its first mission to Artemis 1, sending an unmanned Orion capsule into orbit around the moon. . NASA has announced that the names of those interested can also be sent along with the spacecraft on this trip.

But before Artemis 1 can get off the ground, SLS and Orion, which are two components, must pass a series of important pre-launch tests known as "wet clothes practice.">
NASA officials announced that they plan to remove the Artemis 1 from the massive Vehicle Building (VAB) at NASA's Kennedy Space Center (KSC) in Florida around midnight June 6 (June 16) to reach 39B.
At the same time, this will not be the first Artemis 1 wet dress exercise. NASA's first step in this direction began on April 1, about two weeks after the Moon rocket left VAB. This time, after a similar schedule, they will start practicing wet clothes for approximately 48 hours from June 19.
One of the transmission lines that connects the space launch system to its mobile launch tower occurred. The Artemis 1 team tried three times to refuel the SLS, but ultimately failed to do so, and after stopping training in wet clothes, the Artemis 1 complex finally returned to the assembly building on April 25 for repair.
According to NASA officials, several modifications have been made to the complex. For hydrogen leaks, for example, the connection screws were found to have inadvertently loosened, weakening their sealing. "These seals wear out over time," Alabama said. "We had tightened them before, but we had not inspected their torque at intervals, and now we find that they are depreciated." The Artemis 1 team has taken steps to prevent leaks.
A helium flow check valve and related hardware have now been replaced at the upper SLS stage, called the Temporary Refrigeration Propulsion (ICPS) stage. There have also been changes to ICPS components that are involved in the rapid disconnection between the SLS and the mobile launch tower when it takes off. Additional leak detectors have also been added to system components responsible for managing liquid hydrogen, according to NASA. Describes the work done in Artemis 1 following the early return of SLS to VAB. They have replaced the flight to cover the launcher's instrumentation. According to Lanham, the adjustment provides better protection for the launcher against the hot, humid, and often rainy weather of Florida, especially during the summer months.
Various updates were also made on platform 39B. Part of the SLS wet clothing practice requires refueling and draining the rocket fuel to simulate the steps leading to the actual launch. The launch pad uses gaseous nitrogen to clean the rocket holes and dry the junction, so the 39B platform has been able to increase its capacity over the past few weeks. Tom Whitmeyer "Because this rocket is so big, we need the right amount of equipment, there are a lot of capabilities on the launcher that need gaseous nitrogen," said NASA's Deputy Director of General Exploration Systems.
Now that capacity The enhancement allows the SLS to undergo more extensive surveillance on the launch pad, including a 32-hour nitrogen system test to simulate rocket fuel consumption during launch, as well as ground and avionics systems. "The launcher itself is a very straightforward vehicle, but every time you get into refrigeration operations, you have to go step by step," Whitmeier said.
Artemis 1 can begin preparing for the actual launch. NASA officials have said they plan to launch Artemis 1 in August this year, although no official target date will be set until the wet suit training is complete and all data has been analyzed.Credit: NASA/Ben Smegelsky
