Sure one can whine about an RPi and "industrial reliability" (and all I can think of is that damned SD card...), but hey, it's just a cool movie, and it communicates in a nice way what they do. Also, it sounds like they should have been involved in the Mars helicopter (Ingenuity), which runs Linux and need these types of techniques. Cool podcast on the subject: [0]

But yes, it's a wonderful thing that a fairly-accessible linux distribution is powering space missions in this era. It's long overdue, I think, and many of the JPL folks would probably agree.
I'm having some better experiences with SD cards marketed as "high endurance". Another trick I've been doing is to mount /var/log as tmpfs. If they crash when they run out of space, I let them restart themselves.
