The Swiss physicist Thomas Zurbuchen recently retired from his job as Associate Administrator for the Science Mission Directorate of NASA. In a major interview in the newspaper Tages-Anzeiger, he has now taken stock of his six years spent at the US space agency. He admits to having made wrong decisions, the consequences of which proved problematic for him. But in this highly frank conversation, he also expresses pride at his achievements, and insists that “[t]here is no science job in the whole world that is comparable to this”.
