Chinese space officials have revealed the cause of the failure of a Long March 5 rocket last July.

An anomaly in the turbine exhaust system caused a reduction in the thrust of the first stage, resulting in the failure. according to a statement released by the State Administration of Science, Technology and Industry for National Defense (SASTIND).

Engineers have conducted multiple hot-fires on the ground to verify the effectiveness of modifications to the system, the statement said.

The third launch of a Long March 5 booster will occur at the end of the year. The booster will then be used to launch the Chang’e-5 lunar sample return mission next year.
