upper stage was stacked on July 6. Following the completion of umbilical retract testing and integrated modal testing, the Orion stage adapter with ten secondary Artemis I (November 16 – December 11, 2022), formerly Exploration Mission-1 (EM-1), was an uncrewed Moon-orbiting mission. As the first major spaceflight of NASA's Artemis program, Artemis I marked the agency's return to lunar exploration after the conclusion of the Apollo program nearly five decades earlier. It was the first integrated flight test of the Orion spacecraft and Space Launch System ( SLS… On March 17, 2022, Artemis I rolled out of High Bay 3 from the VAB for the first time to perform a pre-launch wet dress rehearsal (WDR). The initial WDR attempt, on April 3, was scrubbed due to a mobile launcher pressurization problem. A second attempt to complete the test was scrubbed on April 4, after problems with supplying gaseous nitrogen to the launch complex, liquid oxygen temperatures, and a vent valve stuck in a closed position. During preparations for a third attempt, a helium check valve on the ICPS upper stage was kept in a semi-open position by a small piece of rubber originating from one of the mobile launcher's umbilical arms, forcing test conductors to delay fueling the stage until the valve could be replaced in the VAB. The third attempt to finish the test did not include fueling the upper stage. The rocket's liquid oxygen tank started loading successfully. However, during the loading of liquid hydrogen on the core stage, a leak was discovered on the tail service mast umbilical plate, located on the mobile launcher at the base of the rocket, forcing another early end to the test. NASA rolled the vehicle back to the VAB to repair the hydrogen leak and the ICPS helium check valve while upgrading the nitrogen supply at LC-39B after prolonged outages on the three previous wet dress rehearsals. Artemis I was rolled back to the VAB on April 26. After the repairs and upgrades were complete the Artemis I vehicle rolled out to LC-39B for a second time on June 6 to complete the test. During the fourth wet dress rehearsal attempt on June 20, the rocket was fully loaded with propellant on both stages. Still, due to a hydrogen leak on the quick-disconnect connection of the tail service mast umbilical, the countdown could not reach the planned T−9.3 seconds mark and was stopped automatically at T−29 seconds. NASA mission managers soon determined they had completed almost all planned test objectives and declared the WDR campaign complete. On July 2, the Artemis I stack was rolled back to the VAB for final launch preparations and to fix the hydrogen leak on the quick disconnect ahead of a launch targeted in two launch windows: August 29 and September 5.
