Designing the International Space Station for Reliability
summary
The International Space Station is a modular system assembled piece by piece across 50 assembly flights, started in 1998 and effectively completed in 2011, and it sustains human missions for over 20 years with redundancy rather than perfection. Oxygen systems evolve from the original Russian water electrolysis to the 2006 OGS and a 2018 CO2‑to‑O2 design while electron supplies >50% oxygen and creates long‑standing technical debt. A 2019 EVA is postponed for lack of suit parts, a drilled leak remains unexplained, and on‑station autonomy uses Watson offloads AI and experimental Kubernetes in orbit.
