ControlsCosmic ray strike-rate slider (per-module probability per voting cycle), mission clock speed slider, Fire cosmic ray button for a manual strike, Mission Running/Paused toggle, Reset mission, and a view toggle between TMR (3 modules + voter) and Unprotected (single module) — the reliability chart always tracks both simultaneously.

Three redundant circuit modules run the same computation while simulated cosmic rays strike at random. A downstream majority voter outvotes any single flipped module, so the correct answer survives — compared side by side against an unprotected module that is corrupted by every strike it takes.

⚙ Under the hood

Fire simulated cosmic rays at three redundant spacecraft circuit modules and watch a 2-of-3 majority voter shrug off single-bit upsets that would silently corrupt an unprotected module. Tune the strike rate and mission clock, then compare live reliability curves between Triple Modular Redundancy and an unprotected single module — TMR only fails on the rare coincidence of two or three simultaneous strikes.
