I want to say something like "oh well, this is certainly a non-critical piece of software". Hopefully it's the convenient dashboard and there are other, more hardened consoles for fallback or something.

But in all seriousness, and without glibness or sarcasm: I cannot comprehend how there is any "unexpected" software running on that spacecraft, regardless of operating system.

EDIT*** For those who like me only watched the video and didn't read the thread: This is on a laptop that is non-critical, it is not a part of the spacecraft. Whew. Now I'm sad that one of the Linux distros didn't try to pitch themselves to the astronauts for a sponsorship... Would have been especially on brand for Pop_OS.

They have a diverse range of devices, including iPhones

And connected to the network!
