TED Blog exclusive video: US astronaut Ron Garan is currently on board the International Space Station with five colleagues from the US, Russia and Europe. (This is Garan‘s second trip to the ISS.) For TEDGlobal 2011, he recorded a talk sharing the perspective from space and describing the wide range of scientific experiments that are run on the station during missions, taking advantage of its unique situation — and describing how these developments can then be applied on Earth.
