China's Space Program Thread II

General
The design of CYZ-1 sub-orbital manned spacecraft has passed expert review and the construction of a prototype (CYZ-1-00) will begin next month.

Interstellor has successfully completed a ground verification test of the active thermal protection technology intended for its CYZ-1 sub-orbital manned spacecraft. The system calls for tens of thousands of small channels to be drilled through the spacecraft's skin. Cooling air is blown through the channels to form an insulating layer to protect the spacecraft. The test achieved a cooling efficiency of 58%, exceeding the 50% efficiency obtained through computer simulations.

The Satellite Internet Technology Experiment Satellite is primarily used for technical experiments and verification in areas such as direct broadband connection between mobile phones and satellites, as well as the integration of space and ground networks.
The Radio Management Bureau of the Ministry of Industry and Information Technology (MIIT) reported that the launch carried four internet satellite test satellites, designated 0001-0004, carrying Ka and other frequency band payloads. Seems to be Galaxy-Space comsats with integrated solar panels and phased arrays. Rumors suggest satellites were originally supposed to fly on ZQ-2E late last year or early this year. However, due to technical issues causing repeated delays, LandSpace lost the contract for this launch.

Considering Zhuque-3 is about to test its reuseablility until the later half of this year, which is only a clone of 20-ton-level F9. Meanwhile, Musk has tested 150-ton-level reuseable Starship almost 10 times. China's space program development is lagging too far from US' SpaceX, in terms of reuseable tech, rocket payload capacity, launch quantity, in-service starlink sat numbers, etc. There is a gap of at least 5 years to catch up. :(

Here is an interview with Zhuque-3's vice chief designer.

This thread is for Chinese space development. It is not meant for bragging of SpaceX or US. Reference to foreign development is only welcomed on technical aspect. We don't want to turn this thread to stupid fight of SpaceX vs. China. Why not go to the NASA thread and make your complaints and bragging?

Something worth to note about the CZ-2D launch on April 1st is "mobile broadband direct communication between mobile device and sattelite". It is part of 6G mobile network technology in which the sattelite acts as cell tower. This is different from any internet sattelite network currently in operation, namely Starlink which operate in its own specification. So far I am not aware any other country does this kind of experiment. Seems China is in lead of 6G by a large margin.

Interview: China's lunar exploration achieves systematic progress, says chief designer​

BEIJING, April 1 (Xinhua) -- China's lunar exploration program has made systematic advancements across scientific research, technological innovation, engineering development and international collaboration over the past two decades, Wu Weiren, the chief designer of China's lunar exploration program, told Xinhua.

Wu made the remarks in an interview on Tuesday at the opening of an exhibition at the National Museum of China, which highlights two decades of the country's lunar exploration program.

Wu noted that China's lunar exploration program has produced a wealth of geological and environmental data, uncovering new elements, minerals and phenomena -- greatly enriching humanity's knowledge of the moon.

He said that China has not only achieved breakthroughs in core aerospace technologies, but has also established a unique lunar exploration project system and formed a relatively complete infrastructure system.

"Furthermore, the country has actively promoted international collaboration through data-sharing and joint research initiatives, significantly advancing global lunar exploration efforts," he said.

Looking ahead, Wu said that China plans to launch the Chang'e-7 mission around 2026 to explore the environment and resources of the south pole of the moon. The Chang'e-8 mission, set for around 2028, will conduct experiments for the in-situ utilization of lunar resources.

He revealed that scientists are developing a solar-powered device capable of melting lunar soil at temperatures of 1,400 to 1,500 degrees Celsius to produce "lunar bricks" through 3D printing -- an essential step toward constructing a future lunar research station.
Lunar samples collected by China's Chang'e-5 and Chang'e-6 missions are on display as part of the exhibition.

"This marks the first time in human history that samples from the moon's near and far sides can be observed side by side," Wu said, calling this a major achievement of China's lunar exploration efforts.

He noted that China will make more lunar samples available for global scientific research, fostering discoveries that will benefit all of humanity.

The exhibition, hosted by the National Museum of China and the China National Space Administration, will run for two months.

they talked about 50 LM8 rockets in May, 2023 not in 2021..

LM8 Two large production facilities just completed last year in Tianjin and Hainan.

but yeah from this year we will see multiple LM8 rocket launches. especially improved LM8A.

last month first LM8A improved rocket took first flight. In 2025, the Long March-8 series is scheduled to carry out more than 10 launch missions, with the Long March-8A rocket set to execute 5 to 6 of those missions, the academy disclosed.

Hipefully they this new rockets will repalce the old highly toxic hypogolic rockets. Its time.for China to move on from those old rockets espexizlly since they now have better newer ones. Im.surprised the change is happening at such a slow pace if at all. Giving the way China usually fast on large projects. This area has been rather slow even when newer rockets have been tested and operational already. Yet they are still been used rarely in single digits every year. I believe they can do better than this. Something seems to be hindering this change.

Chang'e-8 is going to validate how to build a house on the moon! The construction can be fully-automated. Material is all from lunar soil. With 3D print tech & solar energy, lunar earth is melted & printed to bricks of different size. Then robots begin house construction.

Here's a CCTV video introducing how it works.
