Overview
- China rolled the Chang'e-7 stack and a Long March 5 Y14 rocket out to Wenchang and announced a launch window around Aug. 23–24, with final functional checks and propellant loading listed as the next steps.
- The mission is a coordinated multi‑craft stack — an orbiter, lander, rover and a propellant‑powered hopper — that will use the Queqiao‑2 relay satellite for communications between Earth and the lunar surface.
- Chang'e‑7's primary science goal is in‑situ volatile work: the hopper will fly into permanently shadowed craters, a drill will collect shallow subsurface samples to about one metre, tiny samples under 1 gram will be sealed and heated above 200°C, and released gases will be measured by laser and mass spectrometers to quantify water and hydrogen‑isotope ratios.
- The orbiter will first image candidate sites for months before a precision lander attempt; China has discussed targeting the Peak Near Shackleton with a sub‑100 metre landing ellipse, and observers estimate a surface touchdown could be attempted later in 2026.
- The mission carries instruments from several countries and, if successful, will inform where water is accessible on the moon and shape choices for a crewed landing before 2030 and a planned International Lunar Research Station in the mid‑2030s.
