Just to mention: The current MARS rover is using a Raspberry Compute Module 3. Several modern space probe also use off-the-shelf technology. Most Ukrainian drones use it too. The IRIS-T missile uses a 1.0Ghz Quadcore ARM. The times when such systems required extreme technology are far gone.
I tried looking for the Mars Rover that is using a compute module and couldn’t find any that were using one which makes sense because it’s not radiation hardened and they need to operate well outside of the temperature range that the modules actually tolerate. They seem to all be using a radiation hardened version of an IBM power PC 750 that is manufactured by a company name BAE. Ignoring that fact though the Mars Rover does not meet the same low latency processing requirements that this meme is referencing so we can move along further.
“Most Ukrainian drives use it too” while I can’t quantify these numbers it does appear that the Ukrainian military uses orange pi’s for their “kamikaze” drones which is good for that application as it’s easy to source and doesn’t require any heavy demand. As for everything else I was able to locate on the subject, it all appears to be typical DSP processors Analog Devices SHARC’s and the TI equivalents such as the TMS320F28335As for the Iris-T I could not find any information one way or another there. It’s indicating high velocity and use of radar so I can’t imagine they are using anything other than a DSP processor as you are going to need to shave every single microsecond of response time to maximize your effectiveness.
What? This is one of the most ridiculous things I’ve read in awhile and people are up voting this misinformation. No rover that’s on Mars is using a rpi. Here are the actual specs: mars.nasa.gov/mars2020/spacecraft/rover/brains/
I googled around to see where you could have gotten this information from. You might be thinking of this educational rover: github.com/nasa-jpl/…/README.md
