Default Space craft operating system programming language?

The recent post regarding os say it is Flight Linux. Are the
spacecraft systems computer programs written in C?

I believe that they are written in any number of programs.
Most spacecraft computers were essentially embedded systems
with Real-Time requirements, so tended to have custom OS's,
hence custom programming at the next layer. The trend is away
from that.

(BTW, there is a minor corollary in that most of the CPU's
were custom, so anything running on them also were custom
designed. It is much, much easier to just program in assembler
than design a computer language to translate to assembly).

Can't answer for what's done in that particular project -- although with
Linux involved, it would be surprising if it wasn't using C -- but C is
certainly quite a common choice for spacecraft software.
