China says Long March 7A rocket launch failed after flight anomaly

China announced on Monday that the Long March 7A rocket carrying the ChinaSat-4B satellite experienced an in-flight anomaly and failed shortly after liftoff from the Wenchang space launch site in Hainan province. The rocket soared at 8:02 p.m. Beijing time (1202 GMT), but shortly thereafter, state news agency Xinhua reported that the mission was unsuccessful, with the cause under investigation. SpaceX CEO Elon Musk echoed this sentiment on social media, stating that "rockets are insanely hard."

The failure marked the rocket's first since its inaugural flight in March 2020, when another in-flight malfunction forced the mission to abort. Prior to this incident, the Long March 7A had completed numerous successful launches, including over a dozen since the malfunction in 2021. The launch video revealed that the rocket was entirely destroyed at a relatively low altitude and velocity, meaning neither the payload nor debris reached orbit.

This mishap is part of a series of missions involving the ChinaSat-4B satellite, which has been equipped with voice, data, radio, and television transmission capabilities. The satellite, identified as Zhongxing-4B by China National Radio (later removed from a Baidu page), is part of the same series as ChinaSat-4A, launched in 2024. The exact role, customers, or capabilities of ChinaSat-4B remain unclear.

The Long March 7A is a medium-lift rocket designed for high-orbit missions. The failure could potentially prompt investigations into other Chinese launches if shared components, manufacturing, or Wenchang launch operations are implicated. China is currently gearing up for the Chang'e-7 lunar mission, set to launch from Wenchang in the second half of 2026. This mission, utilizing a larger Long March 5 rocket, aims to explore the Moon's south pole, including permanently shadowed craters potentially harboring water ice.
