The ancient mythological image of the "Magpie Bridge" has now become the name of a landmark project in China's deep space exploration. "Magpie Bridge" is the world's first relay communication satellite operating at the Earth-Moon Lagrange point L2. Because the Moon always presents only one side to Earth (tidal locking), when a probe lands on the far side of the Moon, it loses direct radio contact with Earth. To solve this communication problem, "Magpie Bridge" was precisely deployed at the L2 point, a special gravitational equilibrium position, allowing it to "overlook" the far side of the Moon and Earth, acting as a perpetual "space signal tower." It relayed commands from Earth to the probe on the far side of the Moon and transmitted the scientific data collected by the probe back to Earth in real time, achieving a historic breakthrough in human exploration of the far side of the Moon.
