The International Space Station (ISS) is a large space station assembled and maintained in low Earth orbit by a collaboration of five space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), CSA (Canada), and their contractors. ISS is the largest space station ever built. Its primary purpose is performing microgravity and space environment experiments.

Sleeping in space is part of space medicine and mission planning, with impacts on the health, capabilities and morale of astronauts

How do astronauts sleep in space?
Between zero gravity and small sleeping quarters, astronauts have to sleep in space, even if it’s difficult.

On the International Space Station (ISS), an astronaut sleeps in quarters roughly the size of a phone booth. They cocoon themselves in a sleeping bag tethered to a wall. There is no “up” or “down” in space. With zero gravity, an astronaut floats around the cabin while sleeping, potentially injuring themselves if not tethered in place.

“It felt odd,” notes Scott Kelly in a recent interview. Kelly is a retired astronaut who spent 520 days in space. It was strange for Kelly to sleep without the weight of a blanket or the comfort of a pillow to rest his head.
