Artemis I WDR Update: Mission Management Team Polls Go, Weather Favorable for Artemis I Wet Dress Rehearsal

The mission management team for Artemis I met this afternoon to review the status of operations and continues to press ahead toward terminal countdown for the wet dress rehearsal test. Meteorologists with the U.S. Space Force Space Launch Delta 45 currently predict favorable weather conditions for tanking operations on Monday, June 20. Weather constraints stipulate there must be less than a 20% chance lightning within 5 nautical miles of the pad during the first hour of tanking. Winds must not be above 37.5 knots and the temperature cannot be below 41 degrees Fahrenheit.

Teams are performing a pre-launch walkdown of the rocket to ensure the Space Launch System is prepared for the upcoming propellant loading operations. Later today, they will configure mobile launcher and pad facility systems and structures, and power up the interim cryogenic propulsion stage.

The mission management team will meet again Monday morning at 6 a.m. EDT or L-8 hours, 40 minutes in the countdown at the beginning of a planned 90 minute built in hold to assess operations and determine whether to proceed with tanking operations.

A summary of the schedule for the wet dress rehearsal test is available here.

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 scheduled to begin at approximately 7 a.m. EDT on June 20.
