Having outlined and articulated the rationales for returning to the Moon and establishing a permanent presence there, the following section consolidates several plans to make these rationales a reality. Numerous commercial companies, national space agencies, and private organizations have independently developed lunar exploration roadmaps for returning to the Moon. While these roadmaps have different underlying rationales, aligning with the various reasons discussed in the previous part of the report, every roadmap shares a basic phased approach moving from (1) robotic investigation, to (2) establishment of infrastructure and habitats, to (3) habitat development, to (4) long-term missions and permanent human habitation, and to (5) establishment of a developed settlement and lunar society.
