I very much doubt they JIT anything, because of the associated fault risk. So it's going to be an interpreter implementation. That means inner loops will run rather slowly. It could still use image processing library, sure. I doubt NASA wants to do much image processing on-board in the first place. Mostly just lossless compression and maybe some thumbnailing, if they can't download everything.
