During a recent fueling process for the Artemis II mission, NASA encountered leaking hydrogen fuel, prompting multiple pauses and ultimately halting the countdown due to a spike in the leak rate. The planned arrival of the four astronauts at Kennedy Space Center was canceled, and they will re-enter quarantine closer to the next launch opportunity. Artemis II will be the first crewed mission for NASA’s Space Launch System and Orion capsule, vital for future lunar exploration. Safety remains NASA’s top priority as they prepare for this historic flight.
