A lunar settlement provides a nearby rehearsal for building the later hub in Martian orbit. From that second base, crews can supervise robotic surface construction and establish the satellite network needed to communicate across Mars. Substantial colonies would likely move underground, increasing the value of staging construction and resource-processing capacity above the planet. An orbital base can also support asteroid-mining operations without repeatedly climbing out of Martian gravity. The infrastructure serves several missions beyond passenger transfer.

Orbital hubs support construction, communications, and resources
Building a lunar base first supplies experience for a Mars-orbit hub that can oversee robotic construction, host communications, process resources, and support asteroid mining.
