Building the Moon Base
NASAs plan for establishing a sustained lunar presence will roll out in three deliberate phases.
Phase One: Build, Test, Learn
NASA shifts from bespoke, infrequent missions to a repeatable, modular approach. Through CLPS (Commercial Lunar Payload Services) deliveries and the LTV (Lunar Terrain Vehicle) program, the agency will increase the tempo of lunar activity, sending rovers, instruments, and technology demonstrations that advance mobility, power generation (including radioisotope heater units and radioisotope thermoelectric generators), communications, navigation, surface operations, and a wide range of scientific investigations.
Phase Two: Establish Early Infrastructure
With lessons from early missions in hand, NASA moves toward semi‑habitable infrastructure and regular logistics. This phase supports recurring astronaut operations on the surface and incorporates major international contributions, including JAXAs (Japan Aerospace Exploration Agency) pressurized rover, and potentially other partner scientific payloads, rovers, and infrastructure/transportation capabilities.
Phase Three: Enable Long‑Duration Human Presence
As cargo‑capable human landing systems (HLS) come online, NASA will deliver heavier infrastructure needed for a continuous human foothold on the Moon, marking the transition from periodic expeditions to a permanent lunar base. This will include ASIs (Italian Space Agency) Multi-purpose Habitats (MPH), CSAs (Canadian Space Agency) Lunar Utility Vehicle, and opportunities for additional contributions in habitation, surface mobility and logistics.

When you're on an airless satellite, "semi-habitable" is just what you want to hear.
