I have experience with EUROPA, which has gone on to have a long life independent of RAX (e.g. I believe it's still used via SACE for the ISS solar arrays). EUROPA is C++, not Lisp, even though Lisp isn't an unusual choice in AI planning.

Maybe it is now (I don't know -- I've been out of that field for over 20 years) but it wasn't then.

I don't doubt that RAX used Lisp, but they replaced it with C++ within a few years, somewhere between HSTS and the second generation of EUROPA. The C++ versions are the ones that have been in 'production', so to speak, for a couple decades now. The early 2000s Mars Exploration Rovers might've been on an old enough version to still be running Lisp, though.
