Some images from the launch of ChinaSat-3B, a telecommunications satellite for voice and video transmission services. The launch was carried out by a Long March 7A and marked the 577th flight of the Long March series.

China’s Effort to Build a Competitor to Starlink Is Off to a Bumpy Start
Of the 90 satellites that Qianfan has launched, 13 seem to have exhibited irregular behavior, namely they didn’t rise up to their target orbit height along with their peers. Qianfan’s second batch, which it launched in October 2024, contained only five satellites that reached their planned height out of 18. these satellites are not necessarily dead—some could be dormant, waiting for better positioning opportunities—but overall, Qianfan’s satellites clearly underperform compared to others. While Starlink started with about a 3 percent failure rate, it has since gone down to less than 0.5 percent. OneWeb with over 600 satellites, contains only two failed ones that are stuck in space.

ITU requires firms to launch their first satellite within seven years of reserving the spectrum, then steadily make progress toward completing their launches within seven years after that. If they don’t, they may have to scale back their intentions. Those requirements could soon become a serious problem for both Guowang and Qianfan.

There’s one serious bottleneck that’s plaguing both projects right now: rocket availability. Qianfan has put out two public procurement requests this year for rocket suppliers but declared them both failures because they didn’t receive enough bidders. While there are several Chinese commercial companies working on developing reusable rockets, none are ready for prime time. “It's possible that in the next couple of years we'll start to see that that bottleneck get resolved, but it's also possible that it remains a pretty substantial bottleneck

High-resolution images from the launch of Zhuque-2E Y2, which successfully inserted six satellites (Tianyi-29, -34, -35, -42, -45, and -46) into orbit. This was the 5th flight of the Zhuque-2 launch vehicle. The six Tianyi satellites were developed by the Tianyi Research Institute that include one InSAR remote sensing satellite Tianyi-42, two optical remote sensing satellites Tianyi-29 and -35, and three experimental space science satellites Tianyi-34, -45, and -46.

Nice images of Tianyi satellites being secured to the launch vehicle.
