Mike Hecht is in charge of the MOXIE experiment on NASA’s Perseverance rover, arriving on Mars in February. The tiny device will test our ability to turn the Red Planet’s plentiful carbon dioxide into oxygen. Someday a scaled-up version may make the oxidizer that will get astronauts back to Earth. Mike also helps lead the groundbreaking Event Horizon Telescope Collaboration that captured the first image of a black hole. Want to win a Planetary Society baseball cap?
