Imagine a laboratory that teaches us more than we have ever known about disease, muscle and bone health, and eyesight. This lab has an environment that impacts the human body in ways we have never seen before. In fact, there is no place like it in the entire world. That is because this lab does not exist on Earth; it is the International Space Station, orbiting nearly 400 kilometers above our planet's surface. Explore the final frontier of outer space, from freeze-dried food and zero-gravity exercise, to a brain surgery robot. See how medical research in space is benefiting life for all of us here on Earth.
