Cislunar As The Practical On-Ramp
- Cislunar space is the practical on-ramp to a solar system economy because it balances proximity to Earth with lower lunar gravity costs.
- Developing depots, tugs, and standards there turns speculative exploration into predictable logistics.
Lunar Gravity Lowers Transport Costs
- The Moon's shallow gravity well makes it cost-effective to produce and ship propellant, water, and materials into orbit.
- That local production reduces launch costs and enables new markets for orbital services and resilience.
Build Depots At Natural Choke Points
- Place depots and services in high-value orbital nodes like LEO, GEO, NRHO, and EML1/EML2 where traffic naturally funnels.
- Standardize interfaces and containers so tugs and depots can interoperate day one.
