Radiation hardness assurance strategies, COTS part selection, and mission assurance practices for space programs.
This category is for discussions of the practical side of getting radiation-tolerant hardware into flight systems. Topics include COTS vs. rad-hard trade studies, lot-to-lot variability in radiation response, radiation design margin (RDM) policies, lot acceptance testing (LAT) strategies, parts screening and qualification, radiation environment definition, shielding analysis, and risk acceptance frameworks. Discussions of standards (MIL-STD-883, ECSS, JEDEC), review board preparation, heritage arguments, and manufacturer engagement are all welcome.
Whether you’re building a risk case for a COTS part, deciding how much margin is enough, or navigating a parts review board, share your questions and experience here.
