Long March 7A explodes after Wenchang liftoff

A Long March 7A rocket carrying the ChinaSat-4B satellite exploded about 90 seconds after leaving the Wenchang space launch site in China’s Hainan province on Tuesday, destroying the payload. Officials said the launch took place at 8:02 p.m. Beijing time before the vehicle suffered a catastrophic malfunction shortly after liftoff.

Authorities said a formal investigation was launched immediately to determine the technical cause of the failure. The loss ends the mission’s objective of placing ChinaSat-4B into orbit, with officials confirming the spacecraft did not survive the incident.

ChinaSat-4B mission ends in total payload loss Long ChinaSat-4B mission ends in total payload loss Long March The rocket was tasked with deploying ChinaSat-4B as part of a telecommunications program. Officials said the satellite was destroyed in the failure, resulting in a total loss of the spacecraft and its planned services for this flight. According to officials, the mission had been tied to an expansion effort in telecommunications infrastructure, and the loss halts this specific phase of that plan. No further technical details about the malfunction were provided in the initial statements. Investigation and safety review expected to delay flights Officials said the failure is expected to disrupt near-term launch activity from the Wenchang facility, which supports a range of missions operating from the southern island site. The incident was described as a clear interruption to the immediate satellite deployment schedule tied to this launch location. Engineers are expected to carry out a comprehensive safety review of the Long March 7A architecture, with corrective actions required before the rocket returns to flight. Officials indicated that future missions using the same launch vehicle design may be delayed while the inquiry proceeds and conclusions are implemented. Authorities have not said how long the investigation Authorities have not said how long the investigation will take, what components are under review, or whether any upcoming payloads will be reassigned to other rockets. Officials also did not disclose additional information about the failure sequence beyond the reported timing after liftoff and the confirmation of payload destruction.

The outcome of the investigation will determine the technical explanation for the malfunction and the scope of any required changes to procedures or hardware. Until that process is completed, the Long March 7A series is expected to remain under heightened scrutiny as officials assess readiness for future launches.
