Read our Privacy noticeChina said a Long March 7A rocket carrying the ChinaSat-4B satellite failed after an in-flight anomaly following liftoff from the Wenchang space launch site in the southern island province of Hainan on Monday. The failure could trigger checks of other Chinese ​launches if investigators identify a problem involving shared components, manufacturing or Wenchang launch operations. SpaceX founder and CEO Elon Musk, commenting on a post about the failed launch on X, wrote "rockets are insanely hard". Chinese authorities have officially said Chang’e-7 is planned for launch in the second half of 2026, but launch observers have identified a possible window late this month. The mission's Long March 5 rocket and spacecraft are at the site.
