The NASA launch director waived off today’s Artemis I launch attempt at approximately at 17:17 CEST (16:17 BST). Teams encountered a liquid hydrogen leak while loading propellant into the core stage of the Space Launch System Moon rocket.  Efforts to address the area of the leak by reseating a seal in the quick disconnect where liquid hydrogen is fed into the rocket did not fix the issue. Engineers are continuing to gather additional data.
