Do high water and design flaws threaten China’s Three Gorges Dam?

7:00 pm

Heavy rain has caused flooding and a major overload to China’s massive Three Gorges Dam, and a Chinese hydrologist is now warning the dam, which he claims has design flaws, could fail at any time.

Rather than commenting on the validity of the images showing the dam’s warping a year ago, Wang said a more serious concern is the cracks and substandard concrete discovered during its construction. He said a failure of the dam would have catastrophic consequences for individuals residing in the lower reaches of the Yangtze River and that they should prepare for evacuation as soon as possible, reported CT Want.

In his interview with Radio France Internationale, the Chinese water expert also criticized the Chinese government and state media for refusing to acknowledge the potential danger of the reservoir. He said that scientists who have spoken the truth have been criminalized by Beijing, resulting in a society with no communication.

According to Chinese stated-owned CNTV, water inside the Three Gorges Dam continues to accumulate and has risen two meters above its flood-prevention level. Although the dam has been hailed by Beijing as one of the greatest engineering achievements in human history, its structural integrity continues to be questioned.

The dam was only completed in 2009, after decades of planning and construction. If it fails it will be a disaster for China and its communist government, much worse that the Wuhan flu has been.

Yutu-2 to resume travels after day of rest

9:58 am

The new colonial movement: After lunar day of no activity, China has reactivated its Yutu-2 rover on its 19th lunar day on the far side of the Moon.

The Yutu 2 rover had remained stationary during lunar day 18 (May 16-29), while teams back on Earth upgraded ground stations in preparation for the Tianwen-1 Mars mission, due to launch in late July or early August. Upgrades to the tracking and command facilities at Jiamusi, northeast China, and Kashi in the northwest were completed June 13 according to CLEP, meaning normal roving service can now resume.

While the rover has been stationary, the Yutu 2 science team have identified a nearby crater for examination. The 4-foot-wide (1.3 meters), 8-inch-deep (20 centimeters) crater contains reflective material which may be similar in nature to suspected impact melt glass the rover discovered last year. After checking out the crater, Yutu 2 will continue its journey northwest from the Chang’e 4 landing site. Yutu 2 has driven a total of 1,469 feet (447.68 meters) since setting down on the far side of the moon in January 2019.

Generally Yutu-2 has averaged about a hundred feet for each lunar day of actual travel.

Dozens of scientists forced out because of foreign ties, mostly with China

9:19 am

An investigation by the National Institute of Health (NIH) has resulted in 54 scientists either resigning or being fired because they had illegally kept secret their financial ties to foreign governments, almost all of which were with China.

Some 54 scientists have resigned or been fired as a result of an ongoing investigation by the National Institutes of Health into the failure of NIH grantees to disclose financial ties to foreign governments. In 93% of those cases, the hidden funding came from a Chinese institution.

The new numbers come from Michael Lauer, NIH’s head of extramural research. Lauer had previously provided some information on the scope of NIH’s investigation, which had targeted 189 scientists at 87 institutions. But his presentation today to a senior advisory panel offered by far the most detailed breakout of an effort NIH launched in August 2018 that has roiled the U.S. biomedical community, and resulted in criminal charges against some prominent researchers, including Charles Lieber, chair of Harvard University’s department of chemistry and chemical biology.

“It’s not what we had hoped, and it’s not a fun task,” NIH Director Francis Collins said in characterizing the ongoing investigation. He called the data “sobering.”

The article, from the liberal journal Science, tries to imply that there is something bigoted about this investigation because the bulk of those forced out happened to be Asian, but that is junk journalism. China itself is bigoted, and targets those of Asian ancestry for its spying. If we are to defend our nation from them, we have to accept the fact that the ethnic statistics here will not be balanced.

The bottom line remains: If you want to get an American government research grant, you cannot have financial ties with hostile foreign governments. And if you lie about those ties, than we can safely assume you are an agent for those hostile governments, and are really a spy subject to arrest and prosecution.

Chinese military officer arrested trying to leave U.S.

3:54 pm

A Chinese military officer who had been participating in research at the University of California in San Francisco under false pretenses was arrested on June 7th as he was trying leave the country with data and information gathered during his stay.

To obtain a visa, Wang allegedly lied about his affiliation with the Chinese military, claiming his service with the People’s Liberation Army had ended in September 2016. In reality, according to the Justice Department, Wang was still associated with the military, which was paying him a stipend while he was in the U.S.

In May, Wang told his supervisor at the university that he was “being recalled to China by his employer, the Fourth Military Medical University, and that he would not return to work at the UCSF lab, thus cutting his fellowship short by approximately one year,” court documents said. Wang also informed his supervisor that he wanted to collaborate remotely from China and that he had already duplicated some of the research conducted at the California laboratory. Court documents said the duplication of research “was previously unbeknownst” to the supervisor in the U.S.

“Wang was instructed by his supervisor in China, the director of the Fourth Military Medical University lab, to observe and document the layout of the lab at UCSF in order to replicate the lab when he returned to China,” the Justice Department said.

The wisdom of the decision by the Trump administration to restrict entry of any Chinese students with ties to the Chinese military is becoming clearer and clearer.

Chinese launch and Rocket Lab scrub

11:36 pm

Electron on launchpad, June 11, 2020

Yesterday China used its Long March 2C rocket to launch an ocean observation satellite, while also testing both grid fins and a revamped fairing. The goal of the grid fins is to control the first stage’s return to Earth so that it won’t crash on top of any homes. The fairing change is to hopefully lead to their capture and reuse sometime in the future.

Late today, or actually early on June 11th, Rocket Lab tried to do its twelve commercial launch, but after three launch tries the high winds won out and they had to scrub. The image to the right shows the Electron rocket on the launchpad. If you look close, you can see the wind whipping the LOX evaporating off the rocket.

The leaders in the 2020 launch race:

11 China
8 SpaceX
7 Russia
3 ULA

The U.S. continues to lead China 13 to 11 in the national rankings.

China launches its new quick-launch Long March 11 rocket

8:43 am

The new colonial movement: China has successfully launched its new quick-launch Long March 11 rocket for the ninth time, placing two engineering test satellites into orbit.

The Long March-11 (Chang Zheng-11) is a small solid-fueled quick-reaction launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT) to provide an easy to operate quick-reaction launch vehicle, that can remain in storage for long period and to provide a reliable launch on short notice.

LM-11 is a four-stage solid-fueled launch vehicle equipped with a reaction control system on the fourth stage.

It is also designed to launch smallsats, and essentially uses military missile technology to do it.

The leaders in the 2020 launch race (for the moment):

9 China
7 Russia
6 SpaceX
3 ULA

The U.S. still leads China 11 to 9 in the national rankings. That lead will widen should SpaceX successfully launch later today.

China reveals its space station launch schedule

9:06 am

The new colonial movement: According to its chief designer, China will complete the assembly of its first multi-module space station over a two year period beginning in early 2021.

The first module for the Chinese space station will launch next year, said Zhou Jianping, chief designer of China’s human spaceflight program, on the sidelines of a political conference in Beijing Tuesday. Launch of the Tianhe core module on a Long March 5B could take place at Wenchang in early 2021. This will be followed by a crewed Shenzhou flight, from Jiuquan, and a Tianzhou cargo mission. The first of two experiment modules will then launch for docking with Tianhe.

In total 11 launches will be conducted to complete the construction of the space station by around 2023, Zhou said (Chinese). These will be the launch of the core and two experiment modules, as well as four crewed spacecraft and four cargo spacecraft. The intensive launch plan was revealed following the successful test flight of the Long March 5B heavy-lift rocket May 5. The missions will be conducted using Long March 5B, Long March 2F and Long March 7 launch vehicles.

They will first launch in 2020 their Mars Tianwen-1 orbiter/lander/rover and their Chang’e-5 lunar sample mission, both using the Long March 5B rocket.

Unless they experience a launch failure along the way, I expect this schedule to occur, as outlined.

Let’s fantasize: If SpaceX can get Starship/Super Heavy operational by 2023 (the company’s present somewhat unrealistic goal), they could send it up to swallow the station whole and bring it back to Earth, just like a James Bond movie.

U.S. universities have pocketed $6 billion from hostile enemy countries

8:57 pm

Our new fifth column: An investigation by the Department of Education has found that U.S. universities have taken $6 billion in unreported donations from hostile coutnries, all of which could be in violation of the law.

A probe by the Department of Education into colleges that accept foreign investments and donations has uncovered $6 billion in previously unreported foreign donations from US adversaries including China and Russia, a report said Friday.

House Republicans were monitoring the investigation into the schools to determine if they were violating Section 117 of the Higher Education Act of 1965, which prohibits an “Institution of Higher Learning” from failing to properly report foreign gifts of $250,000 or more, Town Hall reported.

It also appears that some of those universities are now uncooperative, apparently placing their loyalties more with their foreign backers than with their own country.

This evidence is not surprising, and is reinforced by the numerous arrests in recent months of many university professors taking money secretly and illegally from China. The culture in the American university community has been downright hostile to the United States for decades. In the past it was dressed up as their effort to not be jingoistic. That was a long time ago. For at least two decades the academic community has been an anti-American fifth column, working as much as it can with foreign powers to both indoctrinate its students against their own country, while providing aid and comfort to authoritarian countries like Russia and China.

China’s space station

9:05 am

The new colonial movement: China’s propaganda news services today released an article outlining in a somewhat superficial manner the overall design and program of its first full-sized space station, Tiangong-3.

The article does not really provide any new information that was not already reported back in 2016, except for this intriguing detail:

The Long March-2F carrier rocket and Shenzhou manned spacecraft will be used to transport crew and some materials between Earth and the space station. The Shenzhou can carry three astronauts and be used as a rescue spacecraft in emergency.

Earlier reports had suggested they would be using their as-yet unnamed second generation manned capsule and the Long March 5B for these functions. It now appears that they are planning to use both manned ships, probably beginning with the Shenzhou and transitioning to the new manned capsule over time.

The article also describes again their plan to launch and fly in formation with the station a two-meter optical telescope, maintaining it in orbit during the 10-year life of the station using crew from the station. This concept was one that NASA actually considered when it was first conceiving Hubble, but put aside when it was realized that the U.S. station would not launch in time.

Note also that this Chinese space telescope is only slightly smaller than Hubble, its mirror 2 meters across compared to Hubble’s 2.4 meter diameter. It will thus be the second largest optical telescope ever launched, and if it works will allow for astronomical research that will dwarf all the giant ground-based telescopes western astronomers have spent all their time and millions building in the past two decades, rather than launch several Hubble twins.
