Aidan Cowley's team in Germany is figuring out how we stay on the moon long-term. It’s like the surface of our moon is covered in talcum powder. Everywhere you go, there’s regolith, a fine, powdery substance weathered by billions of years of exposure to everything from solar winds to micro-meteorites. Yet that powder didn’t see Aidan Cowley’s microwave oven coming. “And out come nuggets of melted regolith,” says Cowley, “which we might use to build roads, landing pads or even bricks for habitats on the moon.” The 37-year-old Irishman is a science adviser at the European Space Agency (ESA), leading a peculiar unit called Spaceship EAC, dedicated to experiments like microwaving lunar dust. Around 15 early-career researchers and students work on speculative technologies that can help humans live on the moon — in essence, building their own moon base. What makes them different is a focus on new, crazy ideas rather than short-term projects. “We’re a brainstorming group, slash think tank, slash skunk works,” says Cowley. |
