It is likely they used C. Specifically, C99. I say this because in my 
dealings with NASA (related to my work with CubeSats), the people I've 
talked with made it clear that NASA is now a C shop. Both my colleague 
and I have extolled the virtues of Ada and SPARK to NASA engineers, but 
we get the usual reaction: to much investment in C to take any other 
option seriously... except maybe C++ (JPL, at least, does some work with 
C++ so that might also be on the JWST).
