On March 24, 2026, NASA announced that it intends to pause the Lunar Gateway in its current form and redirect resources toward a phased lunar surface base. Gateway hardware already in production may be repurposed; its Power and Propulsion Element could become a nuclear-electric propulsion demonstrator. The proposed programme includes approximately $20 billion over seven years, with crewed missions planned twice yearly from 2028, while final approval of the Gateway pause remains subject to Congress.
The shift prioritises sustained surface operations over an orbital transfer station. Reported plans include repeatable Commercial Lunar Payload Services missions, Lunar Terrain Vehicles, surface power, communications, mobility, cargo delivery, permanent habitats, scientific laboratories, and local manufacturing. A later phase, targeted for 2032–2036, would support four astronauts on four-week missions. For the Ark, this concentrates development on the infrastructure needed for radiation protection, logistics independence, repair, resource utilisation, and long-duration human presence—but increases exposure to lunar dust, thermal extremes, launch dependence, and single-site failures.
The Ark team should track congressional disposition, NASA’s hardware-repurposing decisions, Artemis surface architecture, international contributions from ESA, JAXA, Canada, and Italy, and the 2028 mission cadence. Research priorities should include redundant power—solar plus fission—buried or shielded archives, autonomous maintenance, local production of oxygen and construction materials, distributed habitats, and preservation systems capable of surviving decades without crew intervention.
