The maneuver: swing behind a planet as it moves along its orbit and its gravity flings you forward — you steal a sliver of its momentum. Pass in front and you're braked instead.
Your job: launch the probe from Earth, chain gravity assists, and push deeper into the cosmos than any probe before. Propellant is nearly gone after launch — the planets are your engine.
