(CNN) When humans finally have the chance to explore Mars, the members of those crewed missions will be millions of miles from home with delayed communications. Before they go, scientists want to understand as much as possible about the potential effects of microgravity and radiation on the human body.
A big step toward this goal was the One-Year Mission, when NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko spent 340 days on the International Space Station from March 2015 to March 2016.
The space explorers spent nearly a year living in the absence of gravity. The data gathered before, during and after their flight contributed greatly to a better understanding of what happens to the human body in space. Both men were tested up to a year after their mission.
