Since Artemis is in the news, here's a little tour of the hardware that is *still* powering the Voyager probes:

And let's not forget the software; Voyager is running on Forth:

NASA’s 1977 computers aboard Voyager are still working in interstellar space

Check out the retro tech powering the spacecraft 15 billion miles from Earth.

@rdnielsen
Is any of the Voyager code available for the public to study? Or the internal JPL training and documentation mentioned in your link?

I don't know of any Forth code or training materials available from JPL or NASA, but I haven't done more than a superficial search. I doubt that any of it is available, though, because, I believe, all that material was classified.

I used Forth in the '80s, but the only remnant left is a publication that is still accessible from archive.org: https://ia800701.us.archive.org/1/items/the-computer-journal-42/tcj_42_January-February_1990_text.pdf
