Overview
- The Long March 7A broke apart about 85 seconds into flight from Wenchang on Monday, Aug. 10, producing a bright flash and debris seen in multiple videos.
- The mission’s ChinaSat/Zhongxing-4B communications satellite was lost and state media confirmed the launch failed while officials opened an investigation.
- Amateur footage and eyewitness reports show the breakup in real time but Chinese authorities have not yet released definitive telemetry or a cause.
- The 7A’s first stage and strap boosters use YF-100 kerosene‑oxygen engines that are shared with other major vehicles, a fact that could prompt inspections or schedule changes for upcoming missions.
- This was the 18th flight of the Long March 7A and its second failure since 2020, and the incident adds to several Chinese launch setbacks this year that may affect commercial and government satellite services.
