China successfully sent the first group of low Earth orbit satellites for a satellite internet constellation from the Wenchang Space Launch Site in south China's Hainan Province on Monday.

The satellites were launched at 6 p.m. (Beijing Time) by a Long March-5B carrier rocket with a Yuanzheng-2 (Expedition-2) upper stage atop the rocket. The satellites have already entered their preset orbits.

The launch marked the 552nd mission of the Long March series of carrier rockets.
