Establish applicable NASA program requirements (electrical power, battery safety, fault tolerance, radiation, workmanship, EMC, and verification). FCC rules generally apply only if the board contains an intentional radiator; spacecraft EMC requirements are separate.
Produce the system architecture, hazard/FMEA analysis, schematic, PCB, component derating/radiation strategy, and qualification/acceptance test plan.
This is safety-critical aerospace hardware and will require review and approval by the mission’s responsible NASA engineering and safety authorities.
