ISV Innes

ISV Innes is a crewed continuous-acceleration interstellar vehicle in advanced definition phase, assigned as the first human-operated transport element within the Proxima Centauri mission architecture.

The vehicle is configured to support a small specialized crew through multi-year isolation, sustained 1 g acceleration, cruise-phase autonomy, orbital operations, and controlled surface-access campaigns. Its design prioritizes closed-loop life support, radiation attenuation, maintainable subsystem architecture, and operational continuity under high-latency mission conditions.

Propulsion and primary power are provided by a full-scale Dual-Core Magnetically Confined Antiproton-Augmented Fusion Reactor (DCMCAAFR), integrated with redundant thermal-control loops, autonomous health management, and mission-phase power distribution. The vehicle functions as the crew-rated reference architecture from which reduced or uncrewed derivatives, including ACEP-class systems, can be validated against a common propulsion and operations baseline.

ISV Innes also includes a dedicated surface-access capability for repeated descent, ascent, and local validation cycles. This enables direct assessment of crew-transfer procedures, surface logistics, vehicle turnaround limits, and in-situ operational constraints beyond orbital reconnaissance alone.

Its primary program role is to validate full-scale propulsion duty cycles, environmental control, crew survivability, autonomous mission management, and surface-interaction procedures under representative interstellar operating conditions, establishing the engineering baseline for subsequent logistics and population-transfer stages.
