Three days after the successful launch of the Huiyan (HXMT) X-ray space telescope, China was back in action with the launch of a new communications satellite from the Xichang Satellite Launch Center. Launch of Zhongxing-9A (also designated ChinaSat-9A) took place at 16:10 UTC using a Long March-3B/G2 (Chang Zheng-3B/G2) launch vehicle from the LC2 launch complex. However, the third stage suffered an issue, resulting in the satellite being placed in the wrong orbit.

@blamedrop: Będą w stanie coś z tym zrobić czy satelita do wyrzucenia?

@Lynx_Lynx: już działa czas pracy zmniejszony z planowanych 15 lat do 5.

In the now-deleted article, Mr Long predicted that the satellite could raise its orbit over a period of around 20 days, leaving ZX-9A with an operational lifetime of 5 years, rather than the designed 15.

@Lynx_Lynx: Ostatecznie satelicie udało się osiągnąć prawidłową orbitę - po wykonaniu 10 manewrów :)
Odbyło się to oczywiście kosztem paliwa jakim satelita dysponował - co spowoduje skrócenie czasu misji.

@Lynx_Lynx:

The satellite used its own propulsion to perform 10 orbit adjustments and Wednesday reached its intended orbit at 101.4 degrees east longitude over the equator at an altitude of 36,000 km.

The satellite's systems and transponders are now operational and Zhongxing-9A has entered a period of on-orbit testing.

An investigation found that the launch issue was caused by an anomaly with the rocket's rolling control thruster, part of the altitude
