I don't know, but I'll guess. Smilie

I would be surprised to find Linux/Unix actually controlling a spacecraft. I would also be surprised if some Linux systems are not in use aboard the ISS. I watch the NASA channel and I've seen the astronauts floating around with notebooks (the computer kind). I did not see an Apple logo so they must be either Linux or Windows.
