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).
