Change-7 Probe and Launch Vehicle Complete Mating, Final Launch Preparations Underway
Summary: In July 2026, the Long March 5 Y14 launch vehicle and the Change-7 probe completed mating at the Wenchang launch site, with final pre-launch status confirmation work fully underway.
According to the China National Space Administration (CNSA), in July 2026, the Change-7 lunar probe successfully completed vertical mating with the Long March 5 Y14 launch vehicle at the Wenchang Spacecraft Launch Site in Hainan, following the completion of final assembly and testing in the technical area. This critical step signifies that the physical connection and electrical interface testing between the probe and the rocket have been fully completed, and the integrated stack is now ready for transfer to the launch pad.
Personnel at the launch site are currently conducting comprehensive final pre-launch status checks on this integrated vehicle. This includes concluding joint inspections and tests on all rocket systems, the probe's various payloads, and the interfaces between the spacecraft and the launch vehicle to ensure all parameters meet the stringent requirements for launch. Technical staff on site report that all preparatory work is progressing smoothly according to schedule. The final launch window will be determined based on the overall mission timeline, weather conditions, and other relevant factors.
The Change-7 mission is a key component of the fourth phase of China's Lunar Exploration Program (CLEP). Its primary scientific objectives include conducting a detailed survey of the lunar south pole, searching for resources such as lunar water ice, and performing comprehensive investigations of the lunar geology and environment. The successful implementation of this mission will lay a crucial foundation for the subsequent Change-8 mission and the establishment of the International Lunar Research Station (ILRS).
