Overview
- The Long March 7A carrying the ChinaSat‑4B (Zhongxing‑4B) communications satellite broke apart about 85 seconds into flight on Monday, destroying the vehicle and its payload.
- State media reported an in‑flight anomaly and China’s space agencies and launch contractor have opened an investigation but have provided few technical details.
- Launch videos and independent analysts show the rocket was destroyed at relatively low altitude and speed, indicating the satellite and major debris did not reach orbit.
- The 7A’s first stage and strap‑on boosters use YF‑100 kerosene‑oxygen engines that are shared with other Long March vehicles, prompting checks and possible schedule uncertainty for upcoming missions.
- The loss is counted as China’s fourth orbital launch failure in 2026 and raises fresh scrutiny of the country’s fast launch tempo and the handling of high‑profile setbacks.
