The Philae spacecraft that landed on Comet 67P/Churyumov–Gerasimenko (67P) had an experiment on board that was driven by a FORTH language processor, the Intersil HS-RTX2010RH.
The experiment/hardware was the The Surface Electric Sounding and Acoustic Monitoring Experiment (SESAME).
Forth gave rise to this bumper sticker: FORTH ♡ IF HONK THEN
What is being used in more recent space missions?
A lot of custom FPGAs and processors like the RAD750. See for example: A HIGH PERFORMANCE COMMAND AND DATA HANDLING SYSTEM FOR NASA’S LUNAR RECONNAISSANCE ORBITER and The New Horizons Spacecraft.
