On the International Space Station (ISS), most of the crew sleep in their own small cabins. If there are not enough of these for everyone on board, an astronaut can sleep in one of the ISS modules. The American quarters are private, soundproof booths where a crew member can also listen to music, use a laptop, and store personal effects in a large drawer or in nets attached to the cabin walls. The cabin also has a reading lamp, a shelf and a desktop.
