Again like with semiconductors, they thought China couldn't do anything without them. Now that China is again making progress they thought was impossible without them and threatens to advance further than the US eventually, they're desperate to save face and not look weak by demanding China submit to all US demands demands so they can cooperate with China or be left behind.

I made a mistake about CZ-9(2021). 2021 was the one with 16 YF-135 (360t single chamber).

In early 2022 presentation (April?), CZ-9 was 26 Mehalox. Now, we see CZ-9 with 24 240t kerolox. So both are variant 2022.

Ah yes that makes sense.

So perhaps they need to be differentiated by "2022-1" and "2022-2"

The China National Space Administration (CNSA) on Sunday released a batch of scientific research results from its first Mars exploration mission.

The Tianwen-1 orbiter had been operating for 780 days and the rover Zhurong had traveled 1,921 meters on the surface of the red planet as of Thursday, according to the CNSA's Lunar Exploration and Space Program Center.

Both the orbiter and rover have completed targeted scientific exploration missions, and acquired 1,480 gigabytes of raw scientific data, the center said.

Using data gathered by Zhurong, Chinese scientists revealed the relationship between the formation of geological features and water activities on Mars by conducting a comprehensive study of these geological features in the landing area.

Chinese scientists have also found hydrated minerals in platy-like rocks, a layer of "

," proving that there has been substantial liquid water activity at the landing area since the Amazonian epoch, which was about 1 billion years ago.

Scientists have also found that the Martian soil has high bearing strength and low friction parameters, revealing the site where the rover landed must have experienced wind and possibly water erosion.

These results revealed the impact of wind and water activities on Mars' geological evolution and environmental changes, and provided support for the hypothesis that there was once an ocean in the Utopian Planitia, according to the CNSA.

In addition, Chinese scientists have obtained a number of scientific results on the relationship between the density of rocks on the Martian surface and the degree of surface erosion, the distribution of ions and neutral particles in the near-Mars space environment, and the gravity field of Mars.

Relevant studies were published in Nature Astronomy, Nature Geoscience and Science Advances.

Future missions will continue to conduct remote sensing surveys and accumulate scientific data, said the CNSA.

The Tianwen-1 probe, consisting of an orbiter, a lander and a rover, was launched on July 23, 2020. On May 15, 2021, it touched down at the pre-selected landing area in Utopia Planitia, a vast Martian plain, marking the first time that China has landed a probe on the planet.

UAE's 2nd lunar rover Emirates-2 will ride aboard Chang'e-7

The latest information on the Chang'e 7 mission:
1) It will be launched toward the end of 2026 on a CZ-5 rocket;
2) The design life is more than eight years, and the total weight is at least 8.2 tons;
3) It consists of six parts: orbiter, lander, Chinese rover, UAE rover, a hopping/flying probe, and a relay satellite;
4) Will land on the lunar south pole and carry out comprehensive and detailed exploration of the topography, material composition, geological structure, space environment, and potential resources of the lunar polar region;
5) Will verify some key engineering technologies for the future lunar research base, such as high-precision fixed-point landing, and verification of the lifespan and reliability of various sensors and detectors in lunar environments.
6) The small leaping/flying probe has a design life of six months. It's capable of repeated takeoff and landing as well as surface crawling. After fully charging its battery using solar power, it will fly into the eternally dark area at the bottom of the lunar south pole impact crater. Using the water molecule and hydrogen isotope analyzers it carries, it will look for water and other volatile substances.
7) Will observe the Earth's magnetic field as well as the magnetosphere (plasmasphere + magnetotail) from the moon. Will build a Lunar-Earth

Wow, that means Chang'e 7 mission will land no less than 4 separate objects on the moon in one go:
  • Yutu-3 rover
  • Emirates-2 rover
  • hopper
  • their combined lander
Plus the lunar orbit relay sat, plus the main orbiter. It's a blood school bus.

I sure hope Yutu-3 carries one of those Zhurong style disposable camera for the occasion. That group shot on the surface with four of them all lined up will be amazing.

At least three versions of CZ-9 have been proposed by Long this year and I think they are no longer relevant to the actual design.

At least three versions of CZ-9 have been proposed by Long this year and I think they are no longer relevant to the actual design.

Meanwhile components exclusive to the original design such as YF-79 are still reaching new development milestones.

Is there going to be an original design CZ-9 first followed by a reusable variant that bears no resemblance to the expendable version?

Do we know what the actual design is or will be?

It would be understandable but foolish to pursue the original CZ-9 configuration from 2011.


The most sensible option would probably be to commit to the latest 24x240t kerolox design, and select which of the existing CZ-9 developmental subsystems to continue working on (either because they would have applications for the 24x240t CZ-9 or because they are technologically beneficial for the industry in general).

Overall, any new rocket type being developed which lacks the ability to be easily adapted to VTVL reusability, should either be redesigned or scrapped.

China’s Tianwen 1 Mars mission wins top international aerospace award

  • Team recognised for making an ‘essential contribution to a deeper understanding of Mars and the solar system’
  • It’s the second time a Chinese group has been granted the honour

received the world’s highest aerospace award in Paris on Sunday.
The International Astronautical Federation (IAF) said the Tianwen 1 mission, which landed on the red planet last year, “offered an innovative option for successful Mars exploration and contributed to the advancement of deep space exploration technology”.

“Tianwen 1 achieved

, landing, and roving on Mars in one mission for the first time in history. The scientific data acquired during the mission made an essential contribution to a deeper understanding of Mars and the solar system,” the federation said.
Sun Zezhou, chief designer of the Tianwen 1 system, accepted the World Space Award on behalf of the team from IAF president Pascale Ehrenfreund at the International Astronautical Congress.

It is the second time a Chinese team has been given the award. Two years ago, scientists from the Chang’e 4 mission were recognised for leading the world’s first robotic spacecraft landing on the far side of the moon. Sun was also the chief designer of that probe.

By Thursday, the Tianwen 1 orbiter had been operating for more than 780 days, the mission’s Zhurong rover had travelled nearly 2km (1.2 miles) across the Martian surface and the mission had fully completed its exploration goals, the China National Space Administration (CNSA) said on Sunday.

Among the first research results published so far, scientists said data and images of an area near the landing site pointed to

which is much more recent than previously thought.

Landing a spacecraft on the surface of Mars is one of the hardest things to do in planetary exploration. Due to the red planet’s low atmospheric pressure, the spacecraft needs to be slowed down around 7 minutes before touching the ground – and do so on its own because it is too far away to receive instructions from the Earth in time.

China and the United States are the only countries to have landed a spacecraft on Mars, and Tianwen 1’s touchdown prompted calls for collaboration between the space nations.

Asked in Paris about cooperation with China, Nasa administrator Bill Nelson reportedly said it was “up to China” and there needed to be openness and transparency from the Chinese side.

However, Nasa is not allowed to cooperate with China because of the Wolf Amendment, a US law that has been in place since 2011 to prevent the agency from working with Chinese commercial or government space agencies on a bilateral basis.
China does not have any law prohibiting cooperation with other spacefaring nations. Three European instruments went up on the Chang’e 4 mission and last week, the CNSA reached an agreement with the United Arab Emirates to help release their Rashid II rover during the Chang’e 7 mission to the moon’s southern polar region around 2026.

, possibly as early as 2031.

The IAF is a non-governmental organisation established in 1951 to promote and coordinate global space activities, with members from major space agencies, companies, and research institutions worldwide.

The federation launched the World Space Award in 2013 to recognise a “most eminent person or team” who has made “an exceptional impact” to the progress of the world space activities.
