I'm a bit disappointed that they didn't take this as a chance to try out cobbling up a "radiation box" and put commercial equipment in that. Surely, that would be a good experiment data point that could be used in future endeavors.
I feel like you could simulate those conditions here on earth pretty accurately. At the very least, it sounds like they have some radiation sensors on the rover, so we will soon have a better idea of what conditions are like.
