For travel to Kazakhstan it makes sense to show a passport of some kind as they want to know why someone is entering the country. Traveling to Baikonur of course being a legitimate reason to enter the country. There's one aspect of this I don't understand entirely. What if the astronaut travels to the ISS from Baikonur, then used some of form return vehicle that lands in US territory? How would we handle that?
