Artemis I WDR Update: Countdown Progresses Overnight, Teams Remain On Track for Monday Tanking Operations

The launch team is making its way through countdown operations and wet dress rehearsal activities remain on track. The mission management team will meet this afternoon to review the status of operations.


Overnight, engineers powered up the Orion spacecraft and the Space Launch System’s core stage. Teams also configured several systems on the ground, rocket, and spacecraft and performed activities to prepare umbilicals that connect the rocket and spacecraft to the mobile launcher and are used to provide power, communications, coolant, and propellant.


NASA is streaming live video of the rocket and spacecraft at Launch Pad 39B and will provide live commentary on the agency’s website beginning with tanking operations on June 20.
