Russia and China to team up to explore Moon?

1:19 pm

Russia and China appear ready to sign a cooperative agreement involving the joint exploration of the Moon from 2018 to 2022.

The deal is expected to be signed this October and will bring significant benefits to both nations, particularly in manned and future missions to the moon….

The bilateral agreement will cover five areas including lunar and deep space exploration, developing special materials, collaboration in the area of satellite systems, Earth remote sensing, and space debris research.

No details yet. Moreover, the deal itself has not yet been signed, so this might all vanish into the ether. It does appear however that Russia’s financial problems are forcing it to partner with others, and China presently has a very sophisticated but inexperienced space program and lots of cash. Russia’s experience would be a great help to China, until they don’t need it anymore. Thus, the logic of the agreement.

Chinese engineers and astronomers fight over new telescope design

9:10 am

A dispute over the design of a new Chinese optical telescope has broken out between the astronomers who will use it and the engineers who will build it.

In April, an international committee convened by [Chinese Academy of Science’s] Center for Astronomical Mega-Science, which is responsible for the project, reviewed the competing designs and recommended the three-mirror option [the preference of astronomer Jiansheng Chen and China’s astronomers]. On 10 July, [Xiangqun Cui, the instrument’s chief engineer] organized her own review committee that picked the SYZ design as better. Cui’s panel “leaned toward one side,” Chen says. And one member says that the three-mirror design was not sufficiently presented, partly because no one from the Huazhong team was there. Cui and Su explain in their open letter that a member of their own group who knows it well introduced the Huazhong design. “Members were repeatedly reminded they could abstain from voting,” they write. One-third of the 21 committee members did abstain.

Meanwhile, to date, more than 130 young astronomers have signed an open letter to the astronomical community urging that the recommendations of the international panel be respected.

The fundamental disagreement, according to Chen, is “whether a large science project should be technically or scientifically oriented.” Cui and Su say the choice is between incorporating “rapidly developing new technologies” that ensure a long life for the facility, or “simply replicating a 10-meter telescope built 30 years ago.”

This spat reinforces the impression gained from the recent other story about China’s inability to find a manager for its newly built radio telescope. Its top-down management approach (where decisions are made by well-connected powerful bureaucrats at the top of the chain of command) produces office politics that generally does not lead to good technical decisions.

China admits it will do nothing to stop North Korea from attacking US

10:25 am

In an official editorial, China has admitted that it will do nothing to stop North Korea from using missiles to attack the US territory of Guam.

Beijing is not able to persuade Washington or Pyongyang to back down at this time. It needs to make clear its stance to all sides and make them understand that when their actions jeopardize China’s interests, China will respond with a firm hand.

China should also make clear that if North Korea launches missiles that threaten US soil first and the US retaliates, China will stay neutral. If the US and South Korea carry out strikes and try to overthrow the North Korean regime and change the political pattern of the Korean Peninsula, China will prevent them from doing so.

In other words, China will not stop North Korea from carrying out its attacks, but if it does so China will also not do anything if the U.S. responds.

The editorial is intellectually dishonest however. It also states,

The real danger is that such a reckless game may lead to miscalculations and a strategic “war.” That is to say, neither Washington nor Pyongyang really wants war, but a war could break out anyway as they do not have the experience of putting such an extreme game under control. [emphasis mine]

The highlighted words are simply wrong. It has been very clear now for several years that North Korea is eager for war, and has been doing everything it can to instigate a conflict.

China has a giant radio telescope and no one to run it

9:04 am

China’s effort to become a major player in the astronomy and space exploration field has run up against a strange problem.

China has built a staggeringly large instrument in the remote southern, mountainous region of the country called the Five hundred-meter Aperture Spherical Telescope, or FAST. The telescope measures nearly twice as large as the closest comparable facility in the world, the US-operated Arecibo radio telescope in Puerto Rico. Radio telescopes use a large, parabolic dish to collect radio waves from distant sources, such as pulsars and black holes—or even alien civilizations.

According to the South China Morning Post, the country is looking for a foreigner to run the observatory because no Chinese astronomer has the experience of running a facility of such size and complexity. The Chinese Academy of Sciences began advertising the position in western journals and job postings in May, but so far there have been no qualified applicants.

Part of the problem here is that it appears the telescope was built by order of the Chinese government, not Chinese astronomers. It would have been better for China to have built something its own astronomers were qualified to run. Instead, they built something to impress the world, and now can’t find a way to use it.

China punishes more than 500 scientists for peer review fraud

8:51 am

An investigation in China has revealed peer review fraud in more than 100 papers, causing that nation to discipline more than 500 researchers.

MOST’s 27 July announcement marked the culmination of an investigation into the mass retraction this past April of 107 papers by Chinese authors that appeared in a single journal, “Tumor Biology.” The papers, published between 2012 and 2016, were pulled after editors found “strong reason to believe that the peer review process was compromised,” Editor-in-Chief Torgny Stigbrand, of Umeå University in Sweden, wrote on 20 April on the website of the publisher Springer. (Springer, an arm of Springer Nature, published “Tumor Biology” until December 2016; the journal is now operated by SAGE Publications.)

Investigators say the authors engaged in an all-too-common scam. “Tumor Biology” allowed submitting authors to nominate reviewers. The Chinese authors suggested “experts” and provided email addresses that routed messages from the journal back to the researchers themselves, or to accomplices—sometimes third-party firms hired by the authors—who wrote glowing reviews that helped get the papers accepted.

As the article notes, the journal is as guilty as these fake scientists.

“Tumor Biology,” which is owned by the International Society of Oncology and BioMarkers, has a history of problems. In 2016 it retracted 25 papers all at once for similar peer-review problems. The journal now has the dubious distinction of having retracted “the most papers of any other journal,” according to Retraction Watch. An investigation by ScienceInsider found that several scientists listed on its editorial board had no relationship with the journal and one had even passed away several years ago. The journal “should also improve their examination system to prevent [abuse by] unscrupulous researchers,” Chen says.

SAGE took over responsibility for publishing the journal “with the agreement that there would be a complete overhaul of the editorial structure and peer review practices of the journal, specifically the use of preferred reviewers,” a SAGE spokesperson wrote in an email to ScienceInsider.

Not surprisingly, the article includes some whining about the harshness of China’s punishments. Of the more than 500 disciplined, 314 were merely co-authors on a paper, and had not directly participated in the fraud. The investigation concluded that they should have been more diligent and aware of what the lead authors were doing, a perfectly reasonable conclusion.

China’s giant single dish radio telescope FAST nears completion

10:19 am

The new colonial movement: The completion of FAST, the world’s largest single dish radio telescope in China, nears completion.

The article over emphasizes one of the telescope’s minor research projects, the search for alien life. However, it also provides a good overview of the telescope’s status. The main dish is finished, and they are presently building the instruments that will use that dish to do astronomical research.

China begins 200-day simulated self-sufficient space station experiment

9:32 am

The new colonial movement: Four Chinese students yesterday began a 200 day experiment, living in a simulated ground-based space station that will attempt to be self-sufficient for the entire time.

The underlying but unstated goal is revealed by this quote:

But the 200-day group will also be tested to see how they react to living a for period of time without sunlight. The project’s team declined to elaborate. “We did this experiment with animals… so we want to see how much impact it will have on people,” Liu, the professor, said.

They aren’t just testing the self-sufficiency of a future interplanetary spaceship. They are also testing the self-sufficiency of a lunar base, which must undergo 14 days of darkness each lunar day. I wonder if the facility is also subjected to no sunlight during these tests.

China planning its own commercial sea launch platform

10:35 am

The new colonial movement: According to one Chinese official, China is developing its own ocean-going launch platform for placing commercial payloads into orbit.

Tang Yagang, vice head of the aerospace division of the No.1 institute of the China Aerospace Science and Technology Corporation (CASTC), said that the technology is not difficult and a sea launch platform can be built based on modifying 10,000-tonne freighters.

China will use solid carrier rockets which rely less on launch facilities and feature mature technology, Tang said, adding that key technology for the carrier rockets will be tested at sea this year and the service is expected to be available for international users in 2018.

This pronouncement suggests that the platform is already mostly built, and that the first test launches will occur this year.

Long March 5 failure occurred at satellite separation

8:57 am

This story notes that the failure of the Long March 5 launch occurred 30 minutes after launch, when the second stage and the satellite were due to separate.

The link also includes footage of the launch through first stage separation and ignition of second stage engines.

It appears therefore that the failure was not in the Long March 5 rocket itself. When satellite separation occurs the second stage has completed its work, so the rocket apparently did its job getting the satellite into orbit. What happened next however remains unknown.

Based on this information it would appear that this failure might not delay later launches of the Long March 5 that much.

China cuts off oil to North Korea

12:03 pm

It’s about time. China’s national oil company has suspended all oil sales to North Korea because of lack of payment.

The reason North Korea doesn’t have the money to buy oil is largely because it hasn’t been able to sell any coal to China. And the reasons for both is likely China’s increasing desire to rein in North Korea’s missile and nuclear arms programs.

Without oil or coal, North Korea’s leadership will find itself hard-pressed to survive.
