It does beg the question of SEU, ie single event upsets, which cause bits of digital circuits to randomly flip, and is much worse at altitude (another nice thing out atmosphere does for us) Circuits must be designed to be rad-hard to be less succeptible to this, increasing cost. Typically space grade ICs are way older and less powerful than the latest commercial offering as a result.
