H2 for the initial boost, stored in expendable tanks, and NH3 for braking and return. Or just braking, actually - in the book there was no fuel aboard the Discovery for a return trip. Anyway, the book said that the combination was used because H2 would give maximum performance for initial boost, and NH3 is easier to store until the braking stage. Correct me if I'm wrong - I haven't read it in a while and I don't have it handy.
