Landspace Identifies Reaction Control System Leak as Cause of Launch Failure

Landspace has concluded a damaged third stage reaction control system that developed a fuel leak caused the failure of the private Chinese launch company’s ZhuQue-1 rocket during its maiden flight on Oct. 27, GB Times reports.

The anomaly, which occurred 6 minutes 42 seconds after liftoff from the Jiuquan Satellite Launch Center, made the rocket go out of control and sent the Weila-1 (Future-1) micro-satellite plunging into the Indian Ocean.

The conclusion is a preliminary one. The company is conducting additional analysis to confirm the finding.

It was the first orbital launch attempt by a private Chinese space company. A number of Chinese commercial startups are competing for business in the orbital and suborbital markets.

Landspace said the three-stage rocket reached an altitude of 337 km (209.4 miles), which means it entered space without achieving orbit.  The booster reached a top speed of 6.3 km/second (14,093 mph), which is below orbital velocity.
