The communications satellite Zhongxing-9A, which was launched from the Long March-3B carrier rocket from southwest China's Xichang Satellite Launch Center at 12:11 a.m. Monday, has failed to enter its preset orbit.

Abnormal performance was identified during the third phase of the rocket launch, according to the China Aerospace Science and Technology Corporation (CASC) Monday.

The exact reason for the failure is under investigation and related parties are taking measures to address the problem and send the satellite into the correct orbit.

The solar panels and communication antennae, however, have been deployed and the satellite system is operating under normal conditions, CASC said.

The Long March-3B has been one of the main carrier rockets for China's high-orbit launch missions.

With a takeoff weight of more than five tonnes, Zhongxing-9A is the first China-made satellite for live radio and television broadcasts.
