GOLDEN, Colorado - Breathe easy: There's good news from Mars.
Tucked inside NASA's Perseverance Mars rover is a device known as MOXIE, short for Mars Oxygen In Situ Resource Utilization Experiment. MOXIE is the first experiment to suck in the planet's thin, carbon dioxide-laden air and transform that native resource into oxygen. The toaster-sized device, if built to a larger scale, can be used not just for astronaut expeditions to Mars for breathing, but also for rocket fuel.
