Everything Natalie Panek had done in her life was with the singular goal of going into space. When finally ousted from the Canadian Space Agency’s latest astronaut recruitment campaign, the aerospace engineer sought solace in Earth’s most beautiful places, bookending her days helping design and build robotic tools to refuel dead satellites and the ExoMars rover’s chassis and locomotion system with weekend backcountry adventures. Reoriented towards this planet right here, she has become a voice for the wilderness of space, that we might balance all our extra-terrestrial exploring with a fierce commitment to leaving no trace.
