As of August 2026, NASA is targeting Artemis IV (early 2028) and Artemis V (late 2028) for crewed lunar landings, and has a Space Reactor-1 'Freedom' demonstration nuclear reactor targeted for launch by end of 2028 -- both on track per stated timelines but neither has occurred yet, and NASA's own Inspector General has flagged schedule risk to the 2028 landing target.
