Chang'e 7 Mission to Explore the Moon's South Pole to 2027, Raising the Possibility That the United States Could Reach the Region First

Officials said the mission would not launch in this year's window but did not provide a specific new date. In a brief statement on Sunday, Chinese authorities said the Chang'e 7 mission did not meet launch conditions. The statement said the mission underwent a comprehensive review in line with the principles of "acting prudently and reliably" and ensuring absolute success.

China did not provide details on the reason for the delay. The mission was planned to launch from the Wenchang Space Launch Site on Hainan Island in the South China Sea aboard a Long March 5 rocket. Chang'e 7 is not a single spacecraft; it includes a lunar orbiter, a lander, a rover, and a small hopping probe.

The systems are intended to reach the Moon's south pole and study the region in detail. The most likely cause of the delay is believed to be weather. Typhoon Narra, affecting the area, carries winds of about 72 km/h and continues to move through the waters between Hainan Island and the Chinese mainland.

The storm is expected to last another two or three days, making it difficult for launch conditions to become suitable within the current window. Chinese official sources have not shared confirmed information about a new launch date. However, claims on social media suggest the next suitable launch window could open in February or March 2027. Such a long wait is thought unlikely to be explained by weather alone.

Lighting conditions at the Moon's south pole and the mission plan requiring Chang'e 7 to spend about 90 days in lunar orbit before landing may also affect the launch schedule. Less likely, a technical problem discovered at the last moment in the complex payload or launch vehicle could have caused the delay. China is quite secretive about its space program, as in many other areas.

Even the names of taikonauts (astronauts) on missions are announced only one day before launch. The delay makes the race between China and the US to reach the Moon's south pole even more critical. Chang'e 7's target is the area around Shackleton Crater, very close to the Moon's south pole.

The region is of great importance for long-term lunar bases. The crater's high rims create permanently shadowed areas where sunlight has not reached for billions of years. These areas may hold water ice and other substances usable in the future, making only a limited number of south pole regions strategically valuable for long-term lunar settlement plans.

No country has yet made a soft landing in one of the Moon's polar regions, which are harder to reach than areas around the lunar equator. While the delay is bad for science, it creates a new opportunity for the US, increasing the chance that America reaches the Moon's south pole before China. The leading candidate is the Blue Moon Mark 1 lander developed by Blue Origin.

The Blue Moon Mark 1 is planned to carry two NASA probes to the Moon's south pole. The vehicle was originally set to launch this year, but the explosion of the company's New Glenn rocket changed things. Still, Blue Origin aims to fly New Glenn again before the end of 2026. While that schedule is ambitious, a Blue Moon launch in the first half of 2027 is possible. In such a scenario, a very close race could emerge between Blue Moon and Chang'e 7. If Chang'e 7 launches in February as suggested, its landing on the lunar surface — after 90 days in orbit — could come in June.
