From the Canadian Air Force to the European Space Agency, Kirsten has had a fascinating journey and she's far from finished. We asked her what it takes to prepare experiments for Station and ensure smooth in-space operation. Tune in to find out more about how she works with astronauts, scientists and her team in this pivotal space role.  ESA is currently recruiting new astronauts.
