can you not put shielding AROUND the device, rather than build hardened processors ?
I can think of one reason - increases weight of the whole package - but perhaps the corresponding cost increase is not so much as buying a radiation hardened 1Ghz processor.
- sasvari 15y agoyou can't shield your devices from every type of radiation up there with a reasonable sized shield. so yes, it's about weight.
- ericHosick 15y agoOne of the interesting things is that there is some really high energy particles running around in space. If you have a lot of shielding, you risk these particles hitting that shielding causing a cascading effect making things worse (My father designed satellites and we used to chat about this stuff when I was a kid).
