The behavior of 20 mice on the International Space Station is helping shed some light on how humans might adapt to living in space.

The female mice were flown out on the International Space Station aboard an uncrewed SpaceX Dragon capsule and spent up to 37 days floating in NASA’s Rodent Habitat. Video footage show that the mice immediately began their usual grooming, feeding, huddling and socializing, but within 10 days of leaving Earth, younger mice began to run in circles around their cage.
