Washington, D.C. – NASA reports that the launch director halted today’s Artemis I launch attempt at approximately 7:34am CT. The Space Launch System rocket and Orion spacecraft remain in a safe and stable configuration.
Launch controllers were continuing to evaluate why a bleed test to get the RS-25 engines on the bottom of the core stage to the proper temperature range for liftoff was not successful and ran out of time in the two-hour launch window.
Engineers are continuing to gather additional data.
