The first batch of internet satellites for China's Guowang megaconstellation launched Monday on the country's heavy-lift Long March 5B rocket. The satellites are the first of up to 13,000 spacecraft a consortium of Chinese companies plans to build and launch over the next decade. The Guowang fleet will beam low-latency, high-speed internet signals in an architecture similar to SpaceX's Starlink network, although Chinese officials haven't laid out any specifics, such as target markets, service specifications, or user terminals. The Long March 5B rocket took off from Wenchang Space Launch Site on Hainan Island, China's southernmost province, at 5:00 am EST (10:00 UTC) Monday.
