China announced that the International Lunar Research Station (ILRS) will be built in two phases, with a basic station targeted for completion by 2035 in the lunar south-pole region.[1] The initial facility is intended to support regular scientific experiments and limited resource development. Expansion is planned for completion by 2045, centred on a lunar-orbiting station and facilities capable of comprehensive research, resource utilisation, and preparation for crewed Mars missions.[1] The architecture includes lunar-surface, lunar-orbit, and Earth-based segments, linked by energy, command-and-information, and surface-transport systems.[1]
For the Ark, the critical development is not a single habitat but an integrated, partially distributed infrastructure designed for sustained operation. The south pole offers strategic value for access to resources and potentially advantageous power conditions, while orbital and Earth segments provide communications, logistics, command, and redundancy. The stated objective of regular experiments, limited resource use, and later stable operation indicates a progression from externally supported research toward autonomous industrial capability—an essential prerequisite for preserving civilisation beyond Earth.[1]
The Ark team should track ILRS milestones, participating countries and organisations, south-pole site selection, power-system designs, resource-extraction demonstrations, autonomous operations, communications architecture, and the transition from the 2035 basic station to the 2045 expanded system. Research should prioritise interoperability and contingency cooperation with ILRS infrastructure, while integrating lessons on distributed command, lunar transport, resource processing, and long-duration autonomous operation into Ark reference designs.[1]
