A Cruiser-Feeder Concept for a Space Transportation System

This paper presents a conceptual framework for a next-generation space transportation system designed to support human expansion to the Moon, Mars, and beyond. Centered on a modular Cruiser-Feeder architecture, the system aims to make space access reliable, reusable, and economically viable, targeting delivery costs under $20 per kilogram to Low Earth Orbit. The Cruiser, operating on permanent cycling orbits, connects celestial bodies and hosts modular life support and docking systems with expansion capabilities. The Feeder, exemplified by the reusable Ring lander, facilitates efficient cargo and crew transfer between planetary surfaces and orbital cruisers as well as between ground locations. Integral to the system is a standardized space container vehicle, enabling scalable logistics and industrial operations across the solar system. This approach promotes commercial opportunities, fosters global technological advancement, and lays the foundation for long-term space settlement and the creation of a space economy.
