It’s getting even more possible to run Julia on an actual satellite. I.e. with StaticCompiler.jl (and possibly, or not helping?):

[GitHub - brenhinkeller/StaticTools.jl: Enabling StaticCompiler.jl-based compilation of (some) Julia code to standalone native binaries by avoiding GC allocations and llvmcall-ing all the things!](https://github.com/brenhinkeller/StaticTools.jl) I’ve just released version 0.3, which brings a lot of major changes. While it’s still a somewhat experimental package, I think it’s at least to some extent ready for other folks to use,…

Not running on Windows, is maybe a feature, not a bug for satellite control. 🙂 And not having GC allocations is a feature for embedded/real-time/satellites. It’s already possible to avoid GC with Julia before all this, but you had huge binaries. Now the smallest are under 9 KB, and while you can use malloc instead of GC, you would also want to not do that in your control loop.
