Even when she was a child, Jingnan Guo was fascinated by space. Today the 28-year-old astrophysicist from China heads a research team at the German University of Kiel. Her team developed an instrument for the US research robot CURIOSITY to measure radiation levels on the surface of Mars for the very first time. That information will help us understand whether conditions on the Red Planet could one day be conducive to life.
