Scott Kelly, a retired U.S. astronaut, spent 520 days in space over four missions. Working in outer space is a lot like working on earth, but with different challenges and in closer quarters. Kelly looks back on his 20 years of working for NASA, including being the commander of the International Space Station during his final, yearlong mission. He talks about the kind of cross-cultural collaboration and decision making he honed on the ISS, offering advice that leaders can use in space and on earth. His memoir is “Endurance: A Year in Space, a Lifetime of Discovery.”
