China's Long March-12 successfully sent the 19th group of low-orbit internet satellites into their preset orbit. On January 19, the country launched the carrier rocket from the Hainan Commercial Spacecraft Launch Site in the southern island province of Hainan.

This powerful rocket can deliver no less than 12 tonnes to low-Earth orbit and at least 6 tonnes to a 700-kilometer Sun-synchronous orbit. It can be configured with either a 5.2-meter or 4.2-meter diameter fairing, depending on mission requirements.
