Overview
- Teams continued the two‑day countdown simulation with supercold propellant loading on the SLS, with NASA reporting liquid‑hydrogen fill troubleshooting while the rocket remained in a safe configuration.
- An unusual cold snap at Cape Canaveral postponed earlier operations, affected purge systems and valves, and prompted thermal protection adjustments on Orion and related hardware.
- NASA has ruled out Feb. 6–7 attempts and is targeting no earlier than Feb. 8 within limited February opportunities, with additional launch windows identified for late February to early March and in April.
- The Artemis II crew—Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen—remains in quarantine in Houston pending a go/no‑go to travel to Kennedy Space Center.
- The mission is a roughly 10‑day lunar flyby to validate SLS and Orion systems with a planned Pacific splashdown, establishing readiness for future lunar landing flights.
