Also his suggestion of scheme changing "Y~ to X~" is likely another mistake. Letter Y is used because it is the first letter in Pinyin of 遥, not because Y has any meaning in Chinese language. The launch would be disignated as 长征十号乙遥一. X is not initial letter of any Chinese words that may be related to launch sequence in my knowledge. In Chinese writting latin letter X is a place holder for "something" when for some reason the "something" is to be obscured
May be "X" refers to the Pinyin of "芯", which means the "core" stage if you put it in the chinese rocketry context. Classic "Y" means the production number of the rocket was given after it leaves the factory. Since the CZ-10B 1st stage could be reusable , they may be need a new name to refer a used 1st stage. I am guessing may be in the future when they starts reuse the 1st stage, the rocket name could be CZ-10B X1Y2, X1 means the No 1 reused 1st stage, Y2 means the expendable 2nd stage or so.

First photos beamed back by TEE-01B satellite that was launched by Ceres-1 yesterday.

claims the TEE-01B satellite was transferred to Iran's IRGC Aerospace Force after it reached orbit in late 2024. They allegedly paid 250m RMB for control of the system. Deal included access to commercial ground stations managed by the Emposat (Beijing based satellite ground stations provider), for real-time control and data transmission.

Maybe build spaceport at the new scs Island? I wonder if it's feasible


This would require all of the encompassing facilities and infrastructures necessary to support that launch site. Rather doubtful that the SCS islands are big enough to house all of them while not requiring the rocket to be carried by barges/ships in between different stages from fabrication and assembly halls until the launch pad.

Yaogan network and Chinese satellite tech.

so this gives a pretty good idea. If they take about 2 hours to pass and a new one flies over every 10 minutes, then you essentially have continuous 24 hour coverage.

More on this from the Japanese

Yaogan 45 and Yaogan 46, launched in September and November last year, were found between 7,000 and 8,000 kilometers in altitude. Their orbits range from 20 degrees north latitude to 20 degrees south latitude, meaning the satellites can cover not only Hawaii and Guam, where U.S. military bases are located, but also the South China Sea, the Indian Ocean and northern Australia.
Experts say the two newly identified MEO satellites can take higher-resolution images and capture smaller targets as they are closer to the ground than GEO satellites. While LEO satellites can only monitor a specific point for a few minutes in a single orbit, the two MEO satellites are believed to be able to monitor a spot for about 80 minutes.
“After MEO satellites determine a general location, LEO satellites can pinpoint the exact location with greater precision,” said a former senior member of the Air Self-Defense Force. “This will enable continuous surveillance of U.S. aircraft carriers and other targets in the Pacific.”
