The International Space Station has been orbiting in lower earth since 1998 and has been continually inhabited since November 2000. The ISS was originally conceived as a staging base for future missions into deep space. As it turns out, lower earth orbit is an ideal setting for scientific research, from physics and meteorology to astronomy and the life sciences. In this episode we talk with three scientists whose projects are using lower earth orbit to deepen our knowledge of biotechnology and its benefits for mankind.
