Following the completion of the Artemis II wet dress rehearsal, NASA leaders provided a detailed briefing outlining what engineers learned during the full fueling test of the Space Launch System (SLS).
Teams successfully loaded liquid oxygen and liquid hydrogen into the rocket and executed much of the countdown timeline. However, a recurring liquid hydrogen leak at the tail service mast umbilical ultimately prevented the test from reaching simulated launch.

Engineers also identified several secondary findings, including timing issues with closeout procedures, minor valve torque adjustments, and intermittent ground communication dropouts. These issues are now under review as NASA prepares for a second wet dress rehearsal.

To allow time for data analysis and corrective actions, NASA has shifted the earliest possible Artemis II launch opportunity to March. Artemis II will be the first crewed mission around the Moon since Apollo and a major milestone in NASA’s Moon-to-Mars exploration strategy.
