On the International Space Station, sleeping can be somewhat of an interesting experience. Astronaut Samantha Cristoforetti gives us a tour of a typical bedroom on the International Space Station in this video.
Because there is no gravity in space, astronauts sleep in a special cushioned sleeping bag that just floats in the zero gravity effect of microgravity. The astronaut notes that most astronauts tie themselves to something so they don't float around, but she prefers to simply float while sleeping.
The bedroom also has two laptops for communicating with people back on Earth, some water for when she feels parched, an alarm speaker for emergencies on the Space Station, and some other personal items.
There are bedrooms above, under, and to either side of the hallway in the International Space Station. The microgravity effects make this possible.
How would you like to sleep like this?
