NASA's revised Artemis architecture has shifted the first crewed lunar landing from Artemis III to Artemis IV in 2028, following a successful Artemis II flight in April 2026 and confirming Artemis III as a 2027 low-Earth-orbit demonstration of docking with commercial landers. This stems primarily from persistent delays in SpaceX's Starship HLS development, including the need for multiple orbital refueling operations, uncrewed lunar demonstrations, and rigorous validation of landing systems that remain incomplete with only months left in 2026. Trader consensus reflects these technical and scheduling realities, though unexpected breakthroughs in Starship flight cadence or accelerated NASA approvals could theoretically compress timelines—though historical patterns suggest such shifts are improbable before year-end.
