HAINAN, China, Oct. 10, 2026 - China launched a Long March 12 rocket from the Hainan Commercial Space Launch Site on 10 October, placing the 27th group of its low-Earth-orbit internet satellites into their planned orbit, the China Aerospace Science and Technology Corporation announced the next day.^[1] Independent launch trackers count nine satellites on the flight,^[2] which was the 671st launch of the Long March rocket family.^[3] The satellites belong to China's national satellite-internet constellation, known outside China as Guowang, which is still under construction.^[4] The network is already in use: it carried a sub-second video call between researchers in the Arctic and the Antarctic.^[5] Impact Insight. Mega-constellations such as Guowang, Starlink and Qianfan plan to put thousands of satellites into low-Earth orbit. Their growth matters for near-Earth space safety rather than asteroids: more satellites mean more close-approach warnings, more avoidance manoeuvres and more potential debris, and their streaks can spoil the telescope images used to find near-Earth asteroids.
