If JuliaCon last week is any indication, there might be more Lisp in space in the future! As long as the runtime size can be shrunk down a bit, but it sounds like that's in the works too.

any video of this ?

  They're starting to be posted, but it will be a few more weeks before they're all uploaded. There was a period for a week or two after juliacon where the raw 6 hour live-streams were up (it was in person this year), but now they are taken down because MIT requires all non-livestreamed videos to be captioned (for accessibility reasons).

    Do you remember the name of the talk, so I can see it when upload

      Slim binaries and better static compilation were mentioned as big future features in the closing remarks, so that'd be a good one to watch - a lot of the people there working in embedded, robotics, or plane satellite projects were excited about those. There weren't any talks I saw where anyone was actually running Julia in space, but Ronan Chagas' "Attitude control subsystem development using Julia" and Corbin Klett's "Realtime embedded systems testing with Julia" both get pretty close and point out reasons why you wouldn't quite want to run Julia on a satellite or plane just yet. Hopefully the videos capture the questions from the audience because there were some good followups!

        These sound like being about Julia proper. How does that fit with your initial "If JuliaCon last week is any indication, there might be more Lisp in space in the future"? Is this about some Lisp written in Julia? Some Lisp with interoperability with Julia? Or it's based on considering Julia itself a Lisp for some reason?

        I'm assuming OP was considering Julia as a pseudo-lisp. Julia doesn't look at all like a Lisp from the outside (no S-exprs except with (https://github.com/swadey/LispREPL.jl https://github.com/swadey/LispREPL.jl) but it takes many of Lisp's deeper lessons. It's (somewhat) homoiconic (see https://stackoverflow.com/questions/31733766/in-what-sense-are-languages-like-elixir-and-julia-homoiconic/31734725#31734725 https://stackoverflow.com/questions/31733766/in-what-sense-a...), has an AST based macro system, and is an expression based language (no statements, everything returns a value), and has first class functions and types. Also multiple dispatch comes from taking CLOS/Dylan and getting rid of some of the parts that make a compiler writer hate you.

If I'm remembering correctly there are some CL compilers that aim for runtime-free small native executables, even with realtime constraints, but I forget which.

  Not CL, but there is ulisp (http://www.ulisp.com/ http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.
