216 RISC-V cores and 16 GB of HBMe look like a pretty nice SoC with not much needed on the outside required to work at the heart of a workstation.
Imagine if ESA created a new "BBC Micro" reference platform...
I can't imagine that these chips would literally be going to space, since none of this is radiation hardened. Or did they decide "F it, we're blasting it up there anyway"?
It doesn't look like it'll be doing anything critical, so might as well throw it up there and see how screwy it gets. Since it seems to be a physically small chip with low power consumption, it might be cheaper to do error checking than proper hardening.
You can place it deep inside a water tank... Or for a short mission.
