NASA’s wet dress rehearsal for the Artemis II mission to the moon encountered a setback on Monday. The crucial test involved fueling the Space Launch System (SLS) rocket with liquid hydrogen and liquid oxygen propellant in preparation for a simulated launch countdown. However, engineers had to halt the flow of liquid hydrogen into the core stage of the SLS due to potential leaks that needed investigation and troubleshooting.
After a temporary pause, NASA resumed fueling and stated that engineers would attempt to complete filling the tank and manage the hydrogen concentration within acceptable limits. Despite the issue with liquid hydrogen, liquid oxygen continued to flow into the core stage uninterrupted. The troubleshooting efforts also involved temporarily stopping the loading of liquid hydrogen into the upper stage, which would carry the Orion crew capsule on its journey around the moon.
Fuel leaks have been a recurring issue, as seen in the testing of Artemis I, the predecessor to Artemis II, which caused delays in the mission launch. Artemis II will involve four astronauts embarking on a 10-day journey around the moon, marking a significant milestone in human space exploration. If the wet dress rehearsal proves successful, the mission is scheduled to launch no earlier than February 8.
