China Scrubs Chang'e 7 Moon Landing, No Launch Window Left This Year

China has called off its Chang'e 7 Moon mission one day before its scheduled launch, with no window left in 2026 to fly it. The China Manned Space Agency said in a one-line statement on Sunday that the mission did not meet the conditions for launch, following what it called a comprehensive assessment made in line with a principle of leaving no room for failure. It gave no further reason.

Chang'e 7 was stacked on a Long March 5 rocket at the Wenchang launch site on Hainan island, already rolled out to the pad after weeks of preparation. The mission consists of four spacecraft: an orbiter, a lander, a wheeled rover and a small hopper designed to jump over a crater rim in search of ice, then hop back out and keep exploring, something no Moon mission has attempted before. The target is Shackleton Crater near the lunar South Pole, a roughly 21-kilometre crater whose permanently shadowed floor is thought to hold water ice built up over billions of years. No country has ever soft-landed a spacecraft at either lunar pole.

China's space agency did not confirm what forced the scrub. Some Chinese outlets pointed to Typhoon Narra, which was sitting in the waters between Hainan and the mainland with winds around 45 miles per hour; state media had warned of torrential rain in Hainan. Space editor Eric Berger noted that a Long March 7A rocket had failed during ascent two weeks earlier and uses the same engine as the Long March 5. He considers an engine problem unlikely, though, given how steadily China had been moving toward launch. With no window left in 2026, the earliest opportunity is expected around February or March 2027, according to unofficial social media reports.

Astrophysicist Richard de Grijs of Macquarie University said Chang'e 7 marks a shift from exploring the Moon to working out whether its resources can actually be used, since evidence for lunar polar water ice already exists. A delayed Chang'e 7 could reach the Moon around the same time as Blue Origin's Blue Moon Mark 1 lander, which is carrying two NASA probes to the South Pole and could fly in the first half of 2027. China's Chang'e 6 mission returned samples from the Moon's far side in 2024, a world first.
