China successfully sent the first group of low-earth orbit satellites for a satellite internet constellation from the Wenchang Space Launch Site in southern Hainan Province on Monday.

At 6:00 p.m. (Beijing Time), a group of satellites was launched by a Long March-5B carrier rocket with a Yuanzheng-2 (Expedition-2) upper stage atop the rocket. The satellites have entered the preset orbits.

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