Most of us can only imagine what the astronauts aboard the International Space Station have experienced. The distance has made it seem unknowable. But December 2012 that all began to change. From the moment Hadfield arrived at the ISS for a five-month mission, he transformed the way we connect to space. Millions followed his every move. His YouTube videos were instantly viral. The Queen and Captain Kirk sent him messages. But even though Hadfield made it look like fun and games, a whole lot of serious science happened up there. Equipment on the ISS measures solar matter to further our understanding of space. There’s research that can only be done in zero gravity that could radically change how medical diagnoses happen here on earth. And tests to figure out how to make space travel safer and more efficient (with a view to making it to the red planet one day). Featuring astronauts past, present and future, scientific collaborators, Hadfield’s secret weapon family member and Mission control staff at the Canadian Space Agency and NASA.
