You mean like for retrofitting an existing satellite? It seems like we're beyond the era of extremely constrained embedded environments, even for space hardware. Several hundred Mhz PowerPC based avionics computers with hundreds of MB of RAM seemed pretty common 15 years ago.

What would a C interpreter do that wouldn't be done better by simply uploading a new compiled binary, though? The source code is most likely less space efficient than machine code.
