Long March 7A Suffers Launch Failure

A Long March 7A booster failed after liftoff from the Wenchang Space Launch Center on Monday, destroying a new technology verification satellite known as Xinjishu Yanzheng-6.

Official Chinese news media acknowledged the failure of the new booster without providing any details concerning the loss. Very little is known about the lost payload.

Long March 7A is an upgraded version of the two-stage Long March 7 booster that was successfully launched two times in 2016 and 2017. Long March 7A employs a third stage powered by two cryogenic YF-75 engines that operate on liquid oxygen (LOX) and liquid hydrogen.

Long March 7A’s first two stages are powered by RP-1 and LOX. The rocket also includes four small strap-on boosters attached to the first stage.

The booster is designed to replace older models of Long March launchers that are powered by toxic hypergolic fuels.
