Mission Reliability & Redundancy Budget

A spacecraft's overall mission reliability is the product of every subsystem's reliability — one weak link and the whole mission is a single-point-of-failure risk. Spend a limited redundancy budget on the subsystem dependency tree and watch overall mission reliability recompute live.

Explore how a spacecraft's overall mission reliability collapses when it's the product of many single-string subsystems, and how spending a limited redundancy budget on the weakest links raises it far more efficiently than spreading it evenly.

⚙ Under the hood

A spacecraft's overall mission reliability is the product of every subsystem's individual reliability — power, thermal, comms, propulsion, avionics, attitude control and payload all sit on the same critical path. Toggle a limited budget of redundant backup units onto the subsystem dependency tree and watch overall mission reliability recompute live, discovering that backing up the weakest single points of failure beats spreading redundancy evenly.
