China sent a new communication technology test satellite into space from the Xichang Satellite Launch Center in its southwest Sichuan Province on Friday.

The Shiyan-21 satellite was launched at 6:55 p.m. (Beijing Time) aboard a Long March-3B carrier rocket and entered the preset orbit successfully.

The satellite will be mainly used for satellite communication, radio and television, data transmission and other services -- as well as for conducting related technical tests and verifications.

This was the 609th flight mission of the Long March carrier rocket series.
