Overview
- Engineers traced the upper‑stage helium blockage to a dislodged quick‑disconnect seal on the ICPS, reassembled the fitting, verified flow, and kept rollout back to the pad on track for later in March.
- NASA lists two‑hour launch windows for Artemis II on April 1 and April 3–6, with a backup opportunity on April 30, as teams also replace select batteries and a core‑stage liquid oxygen seal.
- Artemis II remains a roughly 10‑day crewed lunar flyby to test Orion and SLS systems without a surface landing.
- NASA canceled the Exploration Upper Stage and is not planning to use Mobile Launcher 2, standardizing near‑term missions on the ICPS and aiming for a launch cadence of about every 10 months.
- Artemis III is refocused into a low‑Earth‑orbit docking rehearsal with commercial lunar landers after safety advisors warned of elevated risk, a shift publicly backed by SpaceX, Blue Origin, and former NASA chief Jim Bridenstine.
