Almost all of the safety critical software that runs on the US side of the Space Station is written in Ada. I wrote "almost all" rather than "all" because there are probably some low level device drivers written in assembly. I can't find out in which language / languages the code that runs on the Russian side was written. I wouldn't be surprised if that also is largely Ada.

Non-safety critical software (e.g., anything running on a laptop) is written in a mix of languages.

  @PearsonArtPhoto - If it's safety critical, yes. The safety critical software runs on the so-called Multiplexer-Demultiplexer (MDM) computers and critical display devices. Non-safety critical software runs on laptops.

There are a lot of programs involved in running the ISS. The exact details are difficult to discern, a lot of NASA's software is available via this site, with some restrictions, but here is what I can find.

• Astrobee- Runs the "Robotic Operating System"


• Geolocation via a Python Library


• Some elements use LabView

I'm sure there are many other languages, including C, C++, and C#, among others, but it would be very difficult to get a complete list.
