Teams Press Ahead Toward Artemis I Launch in Late August

Final work continues to prepare the Space Launch System rocket and Orion spacecraft at NASA’s Kennedy Space Center in Florida for Artemis I. Teams have identified placeholder dates for potential launch opportunities. They include: 

      • Aug. 29 at 8:33 a.m. EDT (Two-hour launch window); Landing Oct. 10 
      • Sept. 2 at 12:48 p.m. (Two-hour launch window); Landing Oct. 11 
      • Sept. 5 at 5:12 p.m. (90-minute launch window); Landing Oct. 17 

Technicians now are testing the newly replaced seals on the quick disconnect of the tail service mast umbilical to ensure there are no additional leaks. The seals were replaced to address a hydrogen leak during the final wet dress rehearsal in June. Following testing, teams will complete closeouts to ready that section for flight.  

Engineers are also finishing installation of the flight batteries. Teams installed the batteries for the solid rocket boosters and interim cryogenic propulsion stage this week and will install the core stage batteries next week.  

On Orion, technicians installed Commander Moonikin Campos, who is one of three “passengers” flying aboard Orion to test the spacecraft’s systems.  Commander Campos’s crew mates, Helga and Zohar, will be installed in the coming weeks.
