Echoing everyone else, Mint. Bazzite (which is Fedora based) if you’re planning to run more recent games on it. Mint isn’t bad at running games by any means, Bazzite is just more fine tuned towards it. With Cinnamon/KDE they basically feel like Windows minus the bloat.

They’re not claiming the launch won’t use fuel, just manoeuvring in space, which still solves the problem of getting fuel for manoeuvring while in space. Fuelless launches are a separate issue that other people are working on.

Energy is easy enough to get in space with some solar panels and a battery, while fuel has to be sent with the payload. Even if it’s not good enough for constant function, being able to spin them up long enough for a course correction is a pretty big deal.

I tried it because even with most of the bloat disabled Microsoft still kept threatening to downgrade me to windows 11, so having heard most games were working through proton and knowing gimp and Firefox run natively I figured it was worth giving it a try.
I stayed because with KDE it feels like an “unlocked” windows, windows with all the annoying parts stripped out, delimited, or fixed. Installing it was simple, customising it was extensive and easy, games run better, GIMP loads faster, installing programs from the bazaar is trivial, and it doesn’t run into any more bugs and errors than windows did, so it’s just a net upgrade. Weirdly bugs are often easier to diagnose and fix with the help of a search engine too, because the questions and answers tend to be a lot more in depth and informative than you get with windows.
