My understanding is that these electronics need to be radiation hardened (eg; RADHARD) to prevent them from misbehaving in ways far worse than the Belgian bit flipping incident (https://radiolab.org/podcast/bit-flip). If you want to use commercial off the shelf (COTS) parts, you need to install them in triplicate and have them "vote". (https://apps.dtic.mil/sti/citations/ADA391766)
