Few humans have had the opportunity to see Earth from space, much less live in space. We got to talk to one of these lucky people — NASA astronaut Loral O'Hara. She will soon conclude her nearly seven month stay on the International Space Station. Transmitting from space to your ears, Loral talks to host Regina G. Barber about her dreams in microgravity, and her research on the ISS: 3D-printing human heart tissue, how the human brain and body adapt to microgravity, and how space changes the immune systems of plants.
