# NASA's two-tier lunar architecture removes the cislunar orbital layer in favor of direct surface operations because Starship HLS eliminates the need for orbital transfer nodes

NASA's March 24, 2026 cancellation of Lunar Gateway and pivot to Project Ignition represents an architectural simplification from three-tier to two-tier cislunar operations. The stated rationale is that 'Gateway added complexity to every landing mission (crew transfer in lunar orbit). Starship HLS can reach lunar orbit from Earth orbit directly without a waystation, eliminating the need for the orbital node.' This removes the cislunar orbital servicing layer entirely rather than replacing it commercially. The $20B Project Ignition budget concentrates all infrastructure investment at the lunar surface (south pole base) rather than splitting between orbital and surface nodes. Gateway's completed hardware (HALO, I-Hab modules) is being repurposed for surface deployment, and the PPE is being redirected to Mars missions, indicating this is a permanent architectural shift rather than a delay. This challenges the assumption that cislunar development would naturally proceed through an orbital waystation phase before surface industrialization.
