It's pretty funny to me that the processor on Ingenuity handily outperforms the one on Perseverance by several orders of magnitude.

- dylan604 6y agoThat's the point of the demo. If Ingenuity's processor survives, then NASA can consider these more advanced processors. If it doesn't, then that means continued use of lesser capable but rad hardened processors will still need to be used. OR, it could mean a re-evaluation of mission lengths. if more science can be done using a more capable processor that is known to have a limited lifespan, then that will have to be evaluated against the benefits of longer missions with less processing requirements
- londons_explore 6y agoThey still have a sample size of 1... Surely a better test would be to get 1000 mobile phone processors and put them in a radiation chamber on earth and see how many fail? It would be far cheaper and be better science.
- dylan604 6y agoBut then we'd have no helicopter on mars right now
- anoncake 6y agoMaybe we don't know the composition of the radiation on Mars precisely enough?
- dylan604 6y agoi've never thought about, but i don't recall any of the other probes/rovers reporting back on things like UVA/UVB or anything else like that. However, with no atmosphere or the Martian equivalent to Van Allen belts, wouldn't it be safe to assume that whatever streams out of the sun is reaching the surface? it would be a matter of intensity on the surface vs what type would it not?
- 0_____0 6y agoI reckon it might actually be cheaper to put together a smallsat with 1000 processors on it and stick it in low earth orbit. Building a chamber and finding all the radiation sources you'd need to accomplish such a thing surely is no small task...
