For decades, small satellites have faced a quiet but stubborn constraint: to move quickly and to move wisely required two separate fuel systems, two separate tanks, and a compromise between power and precision. A team at MIT, working with a propellant originally designed to make spaceflight safer, has dissolved that constraint — demonstrating that a single ionic liquid can feed both a chemical thruster and an electrospray thruster, giving even the smallest spacecraft the full range of motion once reserved for far larger machines. The first real-world test arrives this November, when NASA sends
