**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.

## What this stands on

1. CASC announced on 2026-10-11 that it launched a Long March 12 rocket on 2026-10-10 from Hainan Commercial Space Launch Site, successfully placing the 27th LEO internet satellite group into planned orbit. (sorae)
2. Independent international launch tracking sites state 9 individual satellites were carried on this 2026-10-10 Long March 12 mission. (sorae)
3. This 2026-10-10 mission was the 671st total launch conducted for the Long March rocket family. (sorae)
4. The deployed satellites are part of China's under-construction national low Earth orbit satellite internet constellation, referred to externally as the GuoWang network. (sorae)
5. China's Guowang satellite network successfully conducted a sub-second video call between Arctic and Antarctic researchers. (Interesting Engineering)
