Is China’s Yutu-2 lunar rover dead?

According to monthly images taken by Lunar Reconnaissance Orbiter (LRO) of China’s Yutu-2 lunar rover on the far side of the Moon, it has not moved since March 2024, suggesting it is no longer functioning.

โ€œUp to about February 2023 the rover was moving about 7 or 8 metres every drive and typically about 40 m per lunar day. Suddenly the drives dropped to about 3 or 4 m each and only about 8 or 10 m per lunar day,โ€ Stooke said in an email.

โ€œThat lasted until about October 2023, and then drives dropped to only 1 or 2 m each. In March 2024 Yutu 2 was resting just southwest of a 10 m diameter crater, and itโ€™s been there ever since, as revealed by LRO images,โ€ Stooke added.

It is possible the rover is not entirely dead, but there is no way to be sure. China is not generally forthcoming when things fail. For example, it has never acknowledged the shut down of its Zhurong Mars rover, which it had hoped would survive its first Martian winter. When that winter ended however no reports from Zhurong were released by China, which suggested it was no longer functioning. China however did not report this. It simply made believe the rover no longer existed.

It could be China is now doing the same with Yutu-2.

China completes second launch in 2025

China on January 13, 2025 (Chinese time) completed its second launch in 2025, its Smart Dragon-3 (Jielong-3) solid-fueled rocket lifting off from a launch platform off the coast near the city of Haiyang.

Little information was released describing the payload, other than it was “the satellite group CentiSpace-01.”

Japan identifies a Chinese hacker group as the source of 210 attacks since 2019

The Japanese government has now identified a Chinese hacker group — dubbed “MirrorFace” and likely working with government support and direction — as the source of 210 attacks from 2019 to 2024.

Investigations by the agency’s National Cyber Department and police nationwide found that the malware used by MirrorFace was similar to that employed by the “APT10 Group,” a hacker organization said to be associated with China’s Ministry of State Security.

The targets also aligned with China’s areas of interest and the attacks coincided with Chinese working hours, ceasing during the country’s long holidays, police noted.

Though Japan’s space agency JAXA was a major target, it appears the hackers had many successes with other government agencies, including those related to national security.

This story only adds weight to the previous reports [pdf] of Chinese hacks of JPL, whereby China got the plans of our Spirit and Opportunity Mars rovers and used that information to design Zhurong, its first rover to go to Mars.

China completes its first launch in 2025

SpaceX is no longer the only entity that has launched a successful orbital launch this year. Early today China successfully placed an “experimental” satellite into orbit, its Long March 3B rocket lifting off from the Xichang spaceport in southwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels crashed within China. As for the satellite, China’s state run press merely said that it “was built by its subsidiary Shanghai Academy of Spaceflight Technology and is tasked with verifying orbital refueling and life-extension technologies.”

Chinese pseudo-company gets major cash influx for its Starlink copycat constellation

The Chinese pseudo-company Genesat, which is making the satellites for the 14,000 Starlink-type satellite constellation being developed by the Chinese pseudo-company SpaceSail, has been awarded $137 million in cash from a variety of Chinese sources, most of which are government agencies focused on encouraging development by these pseudo-companies.

Superficially everything about these companies appears real. They compete for contracts and investment capital, and can only function if they make a profit. They also compete with other similar Chinese pseudo-companies. The reality however is that they only exist because the Chinese government wants them to. For example, Genesat was formed by a partnership of SpaceSail and the Chinese Academy of Sciences (which is entirely government-run). And SpaceSail was formed earlier with support of both the national and local Shanghai governments. For example, consider today’s story:

Shanghai Gesi Aerospace Technology, also known as Genesat, announced the more than 1 billion yuan (approximately $137 million) funding round Dec. 30. The main investors include Chinaโ€™s National Manufacturing Transformation and Upgrading Fund, China Development Bank Science and Technology Innovation, Guosheng Capital, SIMIC Capital and Shanghai FTZ Fund.

The first two backers are both government agencies created to funnel government cash to these pseudo-companies.

Overall this approach by the communist Chinese government has worked remarkably well. It has created an robust space industry within a competitive and innovative atmosphere. That industry only exists however as long as the present policies of the Chinese government exist. If there is a major change in leadership it all could vanish in a moment, as there are no property rights in China. A new government could do as Putin did in Russia, consolidate all these pseudo-companies into a central government-run agencies in order to more closely control them.

For the present however China’s pseudo-capitalist approach means it will be a major player in space in the coming years. That success might even lead to a positive change in government, throwing the communists out of power eventually. It is not only demonstrating the advantages of freedom and competition over a top-down command economy, it is developing a class of people doing it. They might eventually have enough wealth and power to take over the government and changes things for real.

China replaces head of its space agency

The man who has headed China’s space agency since 2018 during its most aggressive and successful period, Zhang Kejian, has been replaced by the Chinese government. Zhang has also been removed from another important political post.

Zhang, 63, who has been head of the China National Space Administration (CNSA) since May 2018, is to be removed as Party Secretary of the State Administration for National Defense Science, Technology, and Industry (SASTIND), the agency announced Dec. 26. Shan Zhongde, 54, has been appointed as his replacement. The leader of SASTIND typically also heads CNSA and the China Atomic Energy Authority, both of which are subordinate agencies to SASTIND. CNSA has yet to announce the expected change.

China’s state run press provided no explanation for this change, though it also follows the removal of two other high ranking managers this year from another space agency, CASC, that is supervised by CNSA. Those removals are thought related to reports of corruption.

In the past two decades CNSA administrators went on to become heads of Chinese provinces, the approximate equivalent of a state governor in the U.S. and a somewhat powerful position. It appeared the Xi government was using its space agency as a training ground for its future political leaders. This in turn gave its space operations a favorable political position within the government.

Zhang’s removal in this manner and the rumors of corruption suggest this policy failed in his case. Another possibility is ven more significant if true. It might imply Zhang was involved in some power struggle that threatened Xi and his leadership. If this last possibility is so, the present favored political position of China’s space operations might be seriously threatened. Xi might have decided he did not like the power its leaders have garnered, and is now moving to squash it.

This does not mean the government will now move to reduce its space effort. It could mean however that funding will be more closely watched, and new projects questioned and rejected more easily.

Chinese solid-fueled rocket fails during launch

The commercial division of a Chinese space agency, dubbed CAS Space, late yesterday experienced a launch failure of its solid-fueled Kinetica-1 rocket, lifting off from the Jiuquan spaceport in northwest China.

A statement by the pseudo-company described the failure tersely:

We can confirm that the first two stages were nominal. Stage 3 lost attitude three seconds after ignition and the self-destructing mechanism was activated.

Nothing was said about where the first two stages crashed inside China, or whether they landed near habitable areas.

According to the first link above, this was the second launch failure by China in 2024, which is incorrect. This was the third launch failure for China (see here and here for previous two). That article also says this was the 68th total launch this year, suggesting China has completed 66 successful launches. This does not jive with my count, which presently says China has had 64 successful orbital launches this year. I suspect the two additional launched might have been suborbital tests — such as first stage hop tests (here, here, and here) — which I do not include in these totals. It also might be including the accidental launch of one first stage during a static fire test when it broke free and launched itself unintentional.

More recent information from my readers (see the comments below) suggests that, though the numbers above are not correct, my own count for China’s total successful orbital launches needs adjusting as well. I had marked a March 13th Chinese launch as a failure because the satellites were not placed in their proper orbit. However, using their thrusters engineers were eventually able to get them into place and they are operating. I have therefore increased China’s totals below by one.

American private enterprise still leads the rest of the world combined in successful launches 154 to 97, while SpaceX by itself leads the entire world, including American companies, 134 to 117.

China launches a communications test satellite

According to China’s uninformative state-run press, it today launched “a test satellite for communication technology,” its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No other details about the satellite were released. Nor did the state-run press provide any information about where the rocket’s lower stages, using very toxic hypergolic fuel, crashed inside China.

As is usual for China, it is doing a lot of launches at the end of the year. Though weather might be a factor, I also suspect it is the ordinary “use-it-or-lose-it” symptom of a government-run communist society. Budgets are set for the year. Government agencies find that they better launch or they will lose that budgeted amount in the next year’s budget.

This might not apply to China but if so it would explain its strange end-of-year launch pattern.

Chinese pseudo-company launches four satellites

According to China’s state-run press, China early this morning successfully launched four satellites using a commercial rocket, Ceres-1, that lifted off from an off shore launch platform on the country’s northeast coast.

The rocket supposedly belongs to the pseudo-company Galactic Energy, but China’s state-run press did not think this information was important enough to mention, illustrating why I think the company is not real. The satellites were likely communications satellites intended for one of the several giant satellite constellations China is building, but that information was also left out of China’s reporting.

China and SpaceX complete launches

Two launches today. First China launched four Earth observation radar satellites, its Long March 2D rocket lifting off from its Taiyuan spaceport in northeast China. No word where the rocket’s lower stages, using very toxic hypergolic fuels, crashed within China.

SpaceX then launched a GPS-type satellite for the Space Force, its Falcon 9 rocket lifting off from Cape Canaveral. Little was released about the payload and what information was released was not very informative. The first stage completed its fourth flight, landing softly on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

130 SpaceX
62 China
16 Russia

China launches first set of satellites for planned internet megaconstellations

China today successfully launched an unknown number of satellites in the first launch of one of its planned internet megaconstellations designed to compete with Starlink, its Long March 5B rocket lifting off from its coastal Wenchang spaceport.

Not revealing the number of satellites launched is probably a violation of the Outer Space Treaty, which requires each signatory to inform others of its launches and at a minimum the number of objects placed in orbit. This constellation, dubbed Guowang, is hoping to launch as many as 13,000 satellites, and that will require some coordination to prevent it from interfering with the constellations launched by others. Not revealing the size of this satellite group makes such coordination impossible.

In a bit of good news, it appears China has solved the problem of its Long March 5B rocket, which in the past had used its core stage to place objects in orbit. After payload deployment that core stage would be in an unstable an orbit that would quickly decay, allowing the stage to crash uncontrolled, thus threatening habitable areas worldwide. The rocket’s new upper stage now takes the payloads into orbit, so the core stage can drop off sooner and fall into the ocean harmlessly.

The leaders in the 2024 launch race:

129 SpaceX
61 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 148 to 93, while SpaceX by itself leads the entire world, including American companies, 129 to 112.
