From what I've read, one of the things the helicopter project did was to see how well ignoring the usual heavy verification would go--it used consumer-grade off-the-shelf hardware as well, for instance.

- _joel 5y agoThey have 2 sets of RAM and a RAD hardened FPGA that checks for bitfips in the memory. It can restart one that quickly that it can do it mid-flight. It's amazing what possibilities this could open up as doing intensive image processing on RAD hardened is expensive, or not even possible as it lags behind the state of the art. edit: found the paper https://trs.jpl.nasa.gov/bitstream/handle/2014/46229/CL%2317-6243.pdf https://trs.jpl.nasa.gov/bitstream/handle/2014/46229/CL%2317...
