Deep space exploration is not only a technological contest but also an art of energy and time management. Due to the limited fuel capacity of rockets, directly accelerating to extremely high speeds is often prohibitively expensive and impractical. The gravitational slingshot effect, a kind of "celestial dynamics trick," allows mission planners to "borrow" a portion of a planet's orbital energy from the spacecraft, achieving significant orbital changes and accelerations with almost no fuel consumption. This requires extremely precise calculations of the planet's position, velocity, and the spacecraft's angle and timing of attack. Choosing different planets as slingshots will produce completely different acceleration effects and final trajectories, much like playing a precise game of billiards on a cosmic scale, requiring strategy, prediction, and a deep understanding of the laws of physics. Operating the "Relay Flight" exhibit puts you in the role of a deep space mission commander. Bef
