Tracy Drain is Chief Engineer of the Europa Clipper, a NASA spacecraft currently travelling to Jupiter on a journey that will take six years. Europa is one of Jupiter’s four largest moons, and scientists believe there could be an ocean of liquid water beneath its icy crust. Having water would make Europa one of the best places to look for signs of life in the solar system. Tracy Drain has worked at NASA’s Jet Propulsion Lab for more than two decades. She is also a National Geographic Explorer and was in Australia for the World Science Festival in Brisbane.
