These basic functions prove challenging on International Space Station -- hereโs how astronauts cope
Here are answers to five questions about what โbasicโ life is like for astronauts on the ISS. As if they are going to a restaurant, astronauts can choose which food items they want off of a menu. On the ISS, astronauts use liquid soap, water and no rinse shampoo. Given the microgravity means, there is no up or down, and astronauts can sleep in any orientation, according to NASA. The station has small crew cabins with sleeping bags that astronauts sleep in.
