Scientists Sent Mighty Mice To Space To Improve Treatments Back On Earth

The SpaceX Dragon cargo spacecraft that ferried musclebound mice to the International Space Station and back can be seen at the top of this picture taken from the station on Dec. 20, 2019.

Forty mice spent more than a month in orbit to test two approaches to strengthening muscle and bone in microgravity conditions. The results could help people with muscle and bone diseases.
