Nice “well, actually”. I’m sure Lockheed were building this quad-redundant, radiation-hardened PowerPC that costs millions of dollars and communicates via Time-Triggered Ethernet anyway, whether NASA needed one or not.
Probably, if it already wasn’t developed for DoD.
For example, the OS it seems to be running is integrity 178.

Aerospace tech is not entirely bespoke anymore, plenty of the foundational tech is off the shelf.
Historically, the main difference between ICBM tech and human spaceflight tech is the payload and reentry system.
This is the equivalent of prompt engineering.
