The launch director waived off today’s Artemis I launch attempt at approximately 11:17 a.m. EDT (8:17 a.m. PDT).

Engineering teams encountered a liquid hydrogen leak while loading the propellant into the core stage of the Space Launch System rocket. Multiple troubleshooting efforts to address the area of the leak by reseating a seal in the quick disconnect cavity where liquid hydrogen is fed into the rocket did not fix the issue. NASA engineers are continuing to gather additional data.
