From the first mission to the Moon to subsequent explorations of its far side, China’s Chang’e series probes have written some unique love letters to Earth from 380,000 kilometers away. From Chang’e-1 to Chang’e-5, the Chinese scientists have taken steady steps forward in lunar exploration - each step filled with both thrills and tender moments. The Moon’s surface features a massive arc-shaped structure known as Sinus Iridum. When the lunar rover is near this region, they must navigate around obstacles, a process fraught with tension. In contrast, the sight of rover gently rolling over the regolith exudes a quiet tenderness. When the area surrounding the landing site of the Chang'e-3 probe was later named ‘Guanghan Palace’ by the International Astronomical Union, and when people discovered that the Moon is rich in helium-3 - a resource crucial for the construction of future lunar bases, humanity gradually turned its gaze to the deeper space. Future probes will venture to more distant celestial bodies, and a new chapter of human exploration is set to unfold.
