# NASA's Gateway pivot restructures cislunar architecture from three-tier to two-tier by eliminating the orbital node while accelerating surface ISRU through nuclear power

NASA's announced Moon Base initiative explicitly deprioritizes Lunar Gateway in favor of direct Earth-to-surface operations using HLS (Human Landing System). This collapses the original three-tier Artemis architecture (Earth orbit → cislunar orbit → lunar surface) into a two-tier system (Earth orbit → lunar surface). The pivot features Fission Surface Power (10-40+ kW nuclear systems) as baseline infrastructure, which is the threshold that makes lunar ISRU economically viable for water ice extraction, oxygen production, and propellant manufacture. This architectural shift eliminates Gateway as the orbital propellant depot and crew rotation hub, but potentially accelerates the surface resource utilization layer by removing an intermediate infrastructure dependency. The most likely implementation is SpaceX Starship performing direct lunar transit and using propellant from either ISRU or tanker Starships, fundamentally shifting the cislunar propellant depot market from orbital to surface-based. This represents a structural change in how the cislunar economy develops: instead of building orbital infrastructure first and then surface operations, the new architecture inverts the sequence.
