Executive Summary
The Universal Magnetic Docking Interface is a scalable in-orbit refueling architecture developed to reduce mechanical complexity and improve operational sustainability in spacecraft propellant transfer. The system replaces conventional capture and latching mechanisms with a self-aligning magnetic coupling interface designed for contactless, repeatable engagement under microgravity conditions.
By prioritizing mass efficiency, cross-platform compatibility, and structural reliability, the concept advances infrastructure-level thinking for Artemis logistics, Mars campaign staging, and commercial satellite servicing.
Mission Context
Sustainable deep-space operations require standardized refueling interfaces capable of repeatable engagement without introducing excessive mass or mechanical wear. Traditional docking systems increase failure risk and limit compatibility across spacecraft architectures.
System Architecture
The interface integrates magnetic coupling plates, guided alignment geometry, and sealed propellant transfer pathways. Passive alignment dynamics eliminate mechanical latching systems while maintaining structural stability during engagement. Trade studies evaluated magnetic force requirements, alignment tolerance envelopes, sealing integrity, and coupling repeatability.
Technical Analysis
Structural load paths were analyzed to prevent stress concentrations during docking and separation. Leakage mitigation strategies were incorporated into interface geometry. Performance metrics included coupling strength-to-mass ratio, alignment tolerance sensitivity, and repeatability across engagement cycles.
Validation and Performance
Modeling demonstrated stable coupling behavior and reduced mechanical complexity relative to traditional systems. The architecture achieved mass reduction potential while improving scalability and operational repeatability for long-duration missions.
