Rescue-biased regenerative PLSS architecture study for delayed-ingress astronaut survival: closed-loop life support, isolated emergency O2 reserve, bounded oxygen regeneration, fault-tolerant power continuity, and validation-first systems engineering.

Conceptual research framework exploring the technologies, challenges, and future pathways required for independent human space travel using a personal autonomous spacecraft.

I'm building a Mars habitat simulation where a closed system keeps a crew of 30 alive with no resupply.
