Tim Kopra, Expedition crew getting set for December launch to International Space Station

For this story Steve Brachmann interviewed Tim Kopra, who will be Commander of Expedition 47 aboard the International Space Station… Noting that ISS astronauts were more like lab technicians than scientists, Kopra separated ISS experiments into three main categories. “For some experiments we are the subjects,” Kopra said, especially for those experiments leading to a better understanding of how spending an elongated amount of time in zero-gravity environments affects the human body. Other experiments only require some setup from astronauts after which they run fairly autonomously while still more experiments are installed on the exterior of the ISS and require no astronaut intervention at all.
