Here’s the company and product for the sat reference: https://www.kubos.com/kubos/

Time is irrelevant, it’s about usage and stability. Every rust crate I rely on has published download numbers, which give you an idea of number of people using it. In that set, they are all open source and published on GitHub or Gitlab, so I can look at the codebases easily.

You can wait, that’s fine. But you do end up missing out on helping shape a new environment that is growing at crazy rates over the last few years.

Sorry but that company/product looks like it is a Linux distro and framework tuned/supported for satellite hardware. That does not mean it controls the satellite nor that it is certified.

If you think “download numbers” (or open source, or being in GitHub) is a good metric for measuring reliability, it means you haven’t really worked in any such field.

It isn’t growing _at all_ in many fields, because it is simply way too new (no new software projects started on it), it isn’t certified (or even impossible to certify). That does not mean it is not better, so don’t take that as an attack. It is simply a suicide in risk-analysis to use a new language, new libraries and new compiler front-end in safety-critical projects; so it is a no-go. Similarly for C11, C++14, C++17 and many other languages, frameworks and libraries that you have to approve.

I never have worked in such a field, and you're comments about certification, etc, are definitely things I will accept as true. Getting any support of new technology in any space is hard, and of course takes time.

But, I will say that "download numbers" where there is obvious sustained usage of a project is a stand-in for understanding if something is seeing real-world usage. I don't claim that it show stability, only that if it's usage is high and the number of issues on the project are not growing under that strain then you can begin to get a picture of it's stability.

When you talk about formal proofs, certification, etc. Those are different mechanisms for validating that, but generally requires substantial amounts of money to be done.
