ISV Proxima

ISV Proxima is a large-scale crewed interstellar transport concept representing the final human-transfer stage of the Proxima Centauri mission architecture.

The vehicle is defined for sustained population transport under continuous acceleration, extended mission isolation, and high-latency operational conditions. Its architecture would require mature closed-loop life support, radiation attenuation, distributed habitation systems, autonomous health management, and multi-layer redundancy across propulsion, power, thermal control, and environmental systems.

ISV Proxima depends on prior validation of the full mission chain: autonomous reconnaissance, uncrewed logistics deployment, crew-rated transit, surface-access procedures, and long-duration settlement-support operations. It is therefore positioned as a downstream architecture enabled by the earlier ACEP, ISV Anglada, and ISV Innes program stages.

Its primary engineering purpose is to define the mass, reliability, habitability, and operational-continuity requirements for large human transfer beyond conventional mission scales. At this stage, ISV Proxima remains a forward-defined system architecture rather than an active development vehicle.
