No per diem when clothing, meals and accomodation are provided.
Science Goy has it right -- when meals, etc. are provided, the per diem is currently $3/day for incidental expenses.
Though on the ISS, not sure what they can spend it on... maybe they have some of those coin-operated binocular/telescopes mounted somewhere?
