ISS crew answers questions from space

Yesterday, America's National Public Radio called the International Space Station (ISS) to ask astronauts questions posed by listeners nationwide. Can you see man-made structures on Earth? Does the ISS smell bad? And what is it like in space. Really. From your heart? These and other insightful questions were posed to ISS crew members Thomas Reiter, an ESA astronaut from Germany, Pavel Vinogradov, from Russia, and Jeff Williams, from the USA, by listeners of the popular nationwide NPR radio network. Reiter is currently conducting ESA's first long-duration mission to the ISS.
