I would love to read more technical articles on this if anyone has links.
I got a bit lost by the hyperbole
This level of redundancy is specifically scaled for the rigors of deep space. NASA anticipates transient failures during the Artemis II mission’s transit through the high-radiation Van Allen Belts.
I mean, the vehicle is coasting. I assume the most critical parts of this mission is presumably the reentry vector. And we’re not there yet.
As they say,
Unlike Apollo, the Orion capsule’s computing architecture manages nearly all of the vessel’s safety-critical functions, from life support to communication routing.
You need that to work, preferably at all times :)
"Turn it off and on again" isn't really a palatable option when you're living inside the computer.
