Chang'e 6, 7, and 8 missions will be launched by 2028 to probe the Moon's south pole. The building of the Sino-Russian lunar science station by 2035:

Tianwen-2 probe will be launched in 2025 for a sample return mission to astroid 469219 Kamoʻoalewa. Mars sample return mission to be launched by 2028:

The new configuration of the Long March 9 rocket has 26 200-ton LOX/Methane engines for first stage. The diameter of the core stage has been increased to 11m, and the diameter of the fairing has been increased to 10m:

The development of a two-stage fully reusable LOX/Methane rocket is to be completed by 2035:

If I'm reading this correctly, the '921' crewed lunar rocket (CZ-5DY) is to use a combination of parachute and grid fins for recovery; correct me if I'm wrong. Also, the spaceplane launched on July 16th of 2021 is officially designated as AT-1B:

Also says CZ-5DY will use the chopstick vertical recovery method.
I recall the test gantry for that, it was like the Starship thing but with more wire cables wasn't it?

Tianwen-2 probe will be launched in 2025 for a sample return mission to astroid 469219 Kamoʻoalewa. Mars sample return mission to be launched by 2028:
52023809463_ea4d3a3d2f_k.jpg

A correction: The Tianwen-2 probe to 469219 Kamoʻoalewa will be launched before 2025, not in 2025.

Also, this latest slide conflicts with an earlier presentation on a sample return mission to 469219 Kamoʻoalewa (see illustration at the bottom). In that earlier presentation, the probe was named Zheng He instead of Tianwen-2. Also, the mission was much more complicated and had two parts: first a sample return mission from 469219 Kamoʻoalewa and then a remote observation mission of another astroid named

, all done by the same probe, with the two-part mission lasting almost a decade. The full summary of the earlier presentation is as follows:
The Zheng He probe is scheduled to launch in 2024. It will collect samples from an astroid as well as performing remote observation of another. The probe will land on astroid

and extract samples in 2025. It will then carry the samples back to Earth orbit in 2026 and drop it off by jettisoning the sample returner. The probe – now free of the samples – will fly away to astroid

to perform remote observation, which will take place sometime in 2032.

Interestingly, the probe features both touch-and-go and anchor-and-attach architectures to maximize the chances of a successful landing. Also interesting is the implementation of the anchor-and-attach method. Instead of using a single anchor/drill, the probe features four landing legs, with each leg having its own drill.

Of course, this latest slide may have omitted mentioning the second part of the mission for whatever reason, but my gut tells me that Zheng He may have been deemed too ambitious or risky and thus had been scaled back and re-worked to become Tianwen-2. Now I wonder if the remote observation of 311P/PanSTARRS is still planned and whether a separate probe will be sent for that endeavor.

Does it mean that the new LOX/Methane rocket will mostly be used for SSO launches? If so, why is methane rocket best for SSO launches?

Fresh photos: Spectacular views of Earth from China's space station

China released fresh photos taken from the country's space station on Friday, offering spectacular views of our planet on the 53rd annual Earth Day.
The stunning photos were captured by the Shenzhou-13 taikonauts Zhai Zhigang, Wang Yaping and Ye Guangfu, who completed their six-month mission in orbit and

China is building a near-Earth asteroid defense system and will test it in about 4 years from now. If I am understanding what the deputy director said correctly, the monitoring and early warning components of the system are being built.

"Deputy director of China's national space admin, Wu Yanhua, told the CCTV reporter that China is building a near-Earth asteriod defnese system as a response to the threat of near-Earth asteroids."

"The first step is to complete the land- and space-based monitoring and early warning system. The monitoring system will have a database for the asteroids, in particular those considered critically threatening. Meanwhile, research and study will start for defense technologies."

"The next step is to create the asteroid defense system and develop defense strategies. It will begin with simulation on computers to practice and verify the process (of defense)."

"The final step is to actually test the system on a "threatening" asteroid in 2025 or 2025, i.e. at the end of the 14th 5-year plan. In the test, a spacecraft will be sent to the selected asteroid to observe it in close distance, then strike it to change its course."

国家航天局副局长吴艳华近日在接受总台央视记者专访时表示,我国将着手组建近地小行星防御系统,共同应对近地小行星撞击的威胁,为保护地球和人类安全贡献中国力量。
我们要开始完善建立地基天基对小行星的监测预警系统。这样我们既要编目,而且关键是要分析哪一些是重危型的要进行判断。第二个我们就是要研究探索相关的技术和工程,有没有可能解除这些威胁,我们要进行相关的技术研究和攻关。
同时,我国还将着手组建近地小行星防御系统,组织编制近地小行星防御发展规划,开发近地小天体防御仿真推演软件并组织开展基本流程推演。
我们争取在“十四五”末期或者2025年、2026年实施一次对某一颗有威胁的小行星,既进行抵近观测,又实施就近撞击,就改变它轨道进行技术实验,这样为我们未来人类真正应对小行星地外天体对地球家园的威胁,真正作出我们中国新的贡献。
