During the crucial refueling process, initiated at 12:30 PM ET on Monday, mission managers temporarily halted operations twice to investigate a hydrogen fuel leak emanating from the rear of the rocket.
Although testing of the Orion spacecraft atop the rocket resumed, the hydrogen leak reoccurred in the final moments of the mock launch countdown.
NASA reported that a built-in control system on the rocket, designed to manage the booster in the countdown’s critical final minutes, “automatically halted the countdown due to a sudden spike in liquid hydrogen leakage.”
Engineers are also looking into audio issues that affected communication channels for ground teams during the wet dress rehearsals.
The four astronauts set to embark on Artemis II — NASA’s Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen — were expected to arrive at Kennedy Space Center on Tuesday afternoon after being quarantined in Houston since January 21 to minimize exposure to bacteria before their mission.
However, NASA has confirmed that the astronauts will not proceed to Florida as anticipated and will be released from their quarantine.
Instead, they will undergo quarantine again approximately two weeks before the next targeted launch opportunity, according to agency officials.
Artemis II marks the second flight for NASA’s Space Launch System rocket and Orion capsule, and it will be the first mission with humans on board.
This much-anticipated launch is set to advance NASA’s objectives of returning astronauts to the lunar surface.
The previous unmanned Artemis I lunar orbit mission in 2022 faced a six-month delay due to a hydrogen leak detected during the initial wet dress rehearsal.
The Artemis II flight carries significant importance, being the inaugural crewed mission aboard the Space Launch System rocket and Orion capsule.
“Our highest priority remains the safety of our astronauts, personnel, systems, and the public,” Isaacman stated on X, emphasizing that NASA will “proceed with the launch only when we are confident in our readiness for this historic mission.”
