The human body is incredibly complex. Every part of us—from our bones to our blood cells—is subject to a host of chemical reactions and molecular interactions that, without our conscious effort, keep us alive.

But what happens to these processes when we leave the planet?

In Earth orbit and beyond, where gravity is counteracted by a constant state of freefall and cosmic radiation intensifies, the molecular inner-workings of the human body may change. To find out how, NASA has entered a realm of bio-research known as “-omics.”
