When could Artemis II launch?
Helium flow interruption in the SLS rocket's propulsion stage, caused by a component issue, forces rollback and postpones Artemis II launch from March to April.
- Yesterday, NASA detected an interruption in helium flow to the rocket's upper stage, confined to the SLS interim cryogenic propulsion stage during routine testing.
- After a wet dress rehearsal exposed hydrogen leaks, managers pushed the planned early-February launch; Feb. 6 was the first day of Artemis II mission’s launch window but was delayed by hydrogen fuel leaks.
- Preparing for rollback, teams plan to move the 322-foot SLS rocket back to the Vehicle Assembly Building after NASA said a bad filter, valve, or connector plate could have stalled helium flow.
- NASA now says April is the earliest remaining month for Artemis II, with several April dates listed, after saying `We will begin preparations for rollback, and this will take the March launch window out of consideration`.
- The crew will spend about two days checking Orion's systems and performing a targeting demonstration before the Moon, as part of Artemis II's 10-day mission, with Reid Wiseman as Crew Commander, Victor Glover, Christina Koch, and Jeremy Hansen onboard.
