China's Chang'e-7 lunar probe and Long March-5 rocket have been vertically transferred to the Wenchang Spacecraft Launch Site in south China's Hainan Province. Using an advanced "three vertical, one remote" launch mode, the entire rocket-probe stack remained upright throughout the transfer. Engineers used auto-leveling support points and millimeter-level precision tracks to keep the massive stack stable during the transfer, even in rainy and windy conditions. The transfer marks a major milestone in preparations for China's Chang'e-7 lunar mission.
