Something had to be worked out at NASA for the ISS too, although I don’t know what the imams decided.

DOWN (i.e., toward earth) seems appropriate. Was there any question?

Yes, there was a question. Without knowing how they figured it out, I would assume the direction would be forward in the direction of the orbit although it isn’t a major issue in reality. The time of the prayer has apparently been resolved with a PDA program.
