Overview
- Artemis III is redefined as a mid‑2027 Earth‑orbit mission to practice rendezvous and docking with lunar landers from SpaceX and Blue Origin and to evaluate new spacesuits.
- The first crewed lunar landing shifts to Artemis IV in 2028, a timetable NASA notes would precede China’s stated goal of about 2030.
- NASA cancels the SLS Block 1B/Exploration Upper Stage to simplify hardware, standardize the vehicle, and work toward launches roughly every ten months.
- Artemis II remains in the hangar after hydrogen leaks and a helium‑flow blockage triggered a rollback, with April 2026 as the earliest possible launch window.
- The upper‑stage cancellation carries programmatic and industrial effects reported for Boeing and supplier MT Aerospace, and NASA did not address the Lunar Gateway’s near‑term role in the reset.
