Long March 7A Launch Failure Over Hainan
8/11/2026, 8:24:05 PM
Core Event
On August 10, 2026, a Long March 7A carrier rocket carrying the ChinaSat-4B (Zhongxing-4B) communications satellite exploded about 85 seconds after liftoff from the Wenchang Space Launch Site on Hainan Island. The 60-metre three-stage liquid-fuel launcher broke apart in a fireball that fell into the South China Sea. Both the rocket and its payload were lost.
Background & Context
The Long March 7A is a medium-lift variant of China’s Long March 7 family, designed for geostationary transfer orbit missions. After a maiden-flight failure in March 2020, it returned to service in 2021 and completed more than a dozen successful flights. The August 10 mission was its 18th flight, marking the second recorded failure of the type. ChinaSat-4B is part of a series of communications satellites that provide radio, television and broadband services.
Data & Statistics
- Launch time: 8:02 p.m. Beijing time (8 a.m. ET).
- Failure time: ~85 seconds after liftoff.
- Vehicle height: 60 metres (197 feet).
- Payload mass capability: up to 7 metric tons to GTO.
- Mission count: 18 flights for Long March 7A; two failures (2020, 2026).
- Estimated satellite value: over 1 billion yuan (? $148 million) – SCMP.
Official Statements & Responses
The China National Space Administration did not immediately comment. CASC has not released a technical statement, but officials said the investigation will determine whether the anomaly is isolated to the Long March 7A or requires broader checks of shared components or launch-site operations.
Expert Assessment
Blaine Curcio, founder of Orbital Gateway Consulting, called the incident “not a great development” for the Long March 7A program but noted that “the damage seems limited” based on publicly available information. He said the failure is unlikely to materially affect China’s low-Earth-orbit launch cadence.
On-the-Ground Reports
Videos from spectators near Wenchang showed a bright flash, a thick black smoke plume and debris falling into the sea. Some observers suggested the flight-termination system may have been triggered after the anomaly, a common safety response.
Conflicting Reports & Gaps
- Cause of failure: Xinhua cited a generic “flight anomaly,” while Space.com referenced an “engine malfunction” based on earlier patterns. CNN noted uncertainty over whether the explosion resulted from an anomaly or an intentional flight-termination activation.
- Payload details: Sources identify the payload as ChinaSat-4B/Zhongxing-4B, but precise service capabilities and customer list remain unconfirmed.
These discrepancies highlight the limited technical information released as the investigation proceeds.
Verbatim Quotes

What’s Next
The failure could influence upcoming missions that share similar propulsion technology. China’s Chang’e-7 lunar probe, slated for launch in the second half of 2026, uses a Long March 5 rocket that shares engine families with the Long March 7A. The SCMP forecasted a Long March 5 launch on August 24, 2026; a systemic engine defect could affect that timetable.
The investigation board will review telemetry, propulsion pressure logs and optical tracking data before clearing the Long March 7A fleet for further flights. Until the root cause is identified, future high-orbit launches may face schedule reviews.
