Artemis Replan accelerates lunar cadence with standardized stack and Centaur V

NASA's Artemis replan standardizes hardware, cancels major upgrades, and adopts a near-Block 1 configuration using Centaur V upper stages to push a roughly 10-month flight cadence, targeting annual crewed lunar landings from 2028. Artemis II remains slated for April 2026; Artemis III becomes an all-in-orbit system test with docking to commercial landers before a 2028 surface landing with Artemis IV, while Gateway emphasis is reduced and ML-2 and BOLE are effectively canceled. Michoud production continues for multiple core stages, but several funding, workforce, and integration details remain to be resolved.
