Addendum

I also watched quite a bit of feed from the space station on New Year's Eve. Some guy took us on a tour, showing us the food stash and trash system. Meals came in two colors of container: red (Russian) and blue (USA). I guess if a cosmonaut eats astronaut food, or vice versa, nothing bad happens, which is good, as color codes have a way of failing. Humans will fare better in space if they're not mutually poisonous. As a species, we're designed to be collaborative, history notwithstanding, is my take.
