This document proposes a spacecraft architecture for solar system exploration based on sail propulsion, electromagnetic environmental interaction, distributed sensing, and redundant hull design. The vessel requires zero carried fuel for primary propulsion. All thrust is derived from environmental forces: stellar radiation pressure, solar wind particle momentum, and planetary magnetic fields. The hull, E-sail array, and deployable superconducting loop function together as a distributed sensor system, processed by an autonomous system running on radiation-hard computing substrate. Every subsystem operates within known physics. No new fundamental discoveries are required. Only engineering development.
