Engineers at Swamp Works, part of NASA and the U.S. military’s Office of Naval Research, have designed and built a drone that could someday scout Mars, moons or asteroids in our solar system. Called Extreme Access Flyers, these space-worthy drones could help scientists gather data in places your traditional rover just can’t reach.
