Interesting article from Asia times about China use of Ai to capture or disable satellite
A Chinese research team has reported an experiment in which it says in a simulated space battle.
In a paper published on April 25 in the domestic peer-reviewed journal Aerospace Shanghai, Dang Zhaohui, professor of astronautics from Northwestern Polytechnical University, and his colleagues conducted an experiment in which an AI commanded three small hunter satellites to capture a high-value target, repeating the exercise thousands of times.
The researchers also set penalty parameters for the hunter satellites, such as consuming more fuel and colliding with a teammate. In contrast, the target satellite gained points for each penalty incurred by hunter satellites.

Here is a video segment of the engine test:CASIC has successfully completed a long-duration multiple-ignition test run of the third-stage engine for China's future manned rocket. The engine is now ready for the prototyping stage.
Some info on the Mars sample return mission. Launch 2028, return 2031.
Chinese scientists have developed a metallic-based thermal-control coating for the Shenzhou-14 crewed spaceship that can protect the taikonauts from extreme heat and cold during their six-month stay in orbit.
The new coating works in two ways: providing low solar absorption to help reduce the sun's effect on the spacecraft's internal temperature and providing low infrared emittance to block heat release from internal sources.
Tasked with completing the construction of China's space station, the orbiting Shenzhou-14 taikonauts will witness several complex station configurations during their six-month journey.
Cargo craft and lab modules that dock with the space station core module are likely to block the sunlight to the spaceship, resulting in long-term exposure to the extreme cold found in the shadows of deep space. The spaceship also has to cope with the intense heat found in the direct sunlight of outer space.
Without thermal controls, the temperature of the spacecraft's sun-facing side can soar to above 100 degrees Celsius, while the dark side can plunge to minus 100 degrees Celsius. The extreme high- and low-temperature environments pose challenges to the health of the taikonauts and the functioning of the spacecraft.
Developed by the China Academy of Space Technology, the thermal-control coating was first used on the Shenzhou-13 spacecraft, which was launched on October 16, 2021.
It kept the cabin environment within acceptable temperature ranges (between 18 and 26 degrees Celsius) during its six-month space journey, allowing the taikonauts to stay cool and comfortable in their orbiting home.
China launched the three-person on June 5, providing the third crew for the country's space station project. During their stay in orbit, the crew will witness two lab modules, the Tianzhou-5 cargo craft and Shenzhou-15 crewed spaceship docking with the space station core module.
