Yutu-2 completes 20th lunar day on Moon

10:28 am

The new colonial movement: The Chinese lunar rover Yutu-2 has completed its 20th lunar day on the farside of the Moon, and has now been put in sleep mode for the long lunar night.

Yutu 2 continued on its planned journey to the northwest of the lander, according to the China Lunar Exploration Program (CLEP). The rover covered 90 feet (27.64 meters) during the lunar day to make a total of 1,610 feet (490.9 m) of roving since setting down on the far side of the moon in January 2019.

The article at the link includes some images, including visual data from the ground-piercing radar that suggests at least four layers in the lunar subsurface.

China admits Three Gorges Dam deformed under flood pressure

10:38 pm

Not good: Earlier this week the Chinese government finally admitted what a number of independent writers have noted, that the gigantic Three Gorges Dam has deformed from the record flood waters that are pressing against it this year.

The official Xinhua News Agency quoted the operator of the the world’s largest hydroelectric gravity dam as saying that some nonstructural, peripheral parts of the dam had buckled.

The dam was a pet project of the late Premier Li Peng and a monumental pride of the nation when it blocked and diverted Asia’s largest river in 1997.

The deformation occurred last Saturday when the flood from western provinces including Sichuan and Chongqing along the upper reaches of the Yangtze River peaked at a record-setting 61,000 cubic meters per second, according to China Three Gorges Corporation, a state-owned enterprise that manages the dam and the sprawling power plant underneath it.

The company noted that parts of the dam had “deformed slightly,” displacing some external structures, and seepage into the main outlet walls had also been reported throughout the 18 hours on Saturday and Sunday when water was discharged though its outlets.

Not surprisingly the Chinese government also insisted that the dam is really okay and there is nothing to worry about. And we trust them implicitly, don’t we?

Now for the punchline: If the dam does not hold the city most threatened by it is Wuhan, home to the COVID-19 virus that has panicked the globe.

Another university researcher arrested for spying for China

2:18 pm

The FBI yesterday arrested a researcher who had been working at the University of California-Davis and had lied about here contacts with the Chinese communist party and its military.

Juan Tang, 37, who had been a visiting cancer researcher at UC Davis for several months, left her Davis apartment in June after FBI agents questioned her about evidence that she lied concerning whether she was a member of the Chinese military or Communist Party when she applied for a visa, according to federal court papers.

…U.S. authorities have no authority to enter the consulate without permission, and it was not immediately clear Friday whether she had voluntarily surrendered. Jail records show the FBI arrested her overnight and booking was still in progress Friday morning.

She is one of four Chinese researchers charged by the Justice Department this week for spying. The other three have already been arrested.

Tianwen-1 successfully launched, on its way to Mars

9:27 pm

UPDATE: According to news reports, China tonight successfully launched Tianwen-1 towards Mars, with arrival expected in February 2021.

Below the fold is a live stream of the launch of the Long March 5 rocket. It is not in English, and since it was not linked to China’s mission control, it only covers the first two minutes or so, after which the rocket went out of sight.

The leaders in the 2020 launch race:

17 China
11 SpaceX
7 Russia
3 ULA
3 Japan

The U.S. still leads China 18 to 17 in the national rankings.

Tianwen-1 launch set for July 23rd

3:09 pm

China has rolled out its Long March 5 rocket and is now preparing to launch its Tianwen-1 orbiter/lander/rover to Mars this coming Thursday, July 23rd, some time between 12 am and 3 am (Eastern).

A Long March 5 rocket is set for liftoff with China’s Tianwen 1 mission some time between 12 a.m. and 3 a.m. EDT (0400-0700 GMT) Thursday, according to public notices warning ships to steer clear of downrange drop zones along the launcher’s flight path.

Chinese officials have not officially publicized the launch date. Chinese state media outlets have only reported the launch is scheduled for late July or early August, and officials have not confirmed whether the launch will be broadcast live on state television.

This will be the first operational launch of the Long March 5, which has had three previous test launches, with the first two failing. The success of the December launch, as well as the May success of the related Long March 5B, made this Mars mission possible.

After achieving orbit in February 2021 and spending two months scouting the landing site, the lander will descend to the surface, bringing the rover with it. The prime landing site is Utopia Planitia, in the northern lowland plains.

Utopia Planitia, the prime landing site for China’s Tianwen-1 Mars rover

1:18 pm

More blobs in Utopia Planitia
Click for full image.

Today’s cool image is not only cool, it gives a nice feel for the likely shallow ice table that is probably found close to the surface throughout the lowland northern plains of Utopia Planitia, which is also the prime landing site for China’s Taenwen-1 Mars lander/rover, scheduled for launch sometime in the next four days. [Update: there are now indications the launch will not occur until early August.]

The photo to the right, rotated, cropped, and reduced to post here, was taken on May 9, 2020 and shows a nice collection of strange land forms on the western edge of Utopia Planitia. In this one picture we can see large mounds that might be evidence of cryovolcanic activity (mud volcanoes), strings of small mounds that might be the same but that also suggest underground faults and voids, and distorted and eroded craters that could have buried glacial material in the interiors.

The largest crater in the upper left looks like it is actually filled with ice that has also spilled over to fill the adjacent and linked depression.

This location is quite typical of Utopia Planitia. See for example this post from May 13, 2020: The blobby wettish flows of Mars. In the mid-latitudes here we find ample evidence that buried very close to the surface is an ice table that when hit by an impact melts to form these strangely shaped craters.

China’s actual target landing area is far to the east of today’s cool image, in an area that is appears far less rough. » Read more

Launch update on Mars missions

9:24 am

The launch status of the three missions to Mars:

First, the launch of UAE’s Hope orbiter by Mitsubishi’s H-2A rocket has been pushed back to July 20th due to bad weather. Their launch window extends to August 3rd, so they still have two weeks before it closes.

Second, China has rolled to the launchpad the Long March 5 rocket, with the Tienwen-1 orbiter/lander/rover. Though they have only said that the launch will occur between July 20th and July 25th, based on past operations, they usually launch six days after roll-out, putting the launch date as July 23.

China has also provided some clarity as to Tienwen-1’s landing site on Mars. According to this Nature Astronomy paper [pdf], published on July 13th, their primary landing site is in the northern lowland plains of Utopia Planitia. The Tienwen-1 science team has also considered [pdf] the northern lowland plains in Chryse Planitia, on the other side of Mars.

Since they will spend two to three months in Mars orbit before sending the lander and rover to the surface, it could very well be that they won’t make a final decision until they get into orbit.

Finally, on July 7th Perseverance was mounted on top of its Atlas-5 rocket for its July 30th launch. Its launch window closes on August 15.

Launch failure for China’s new Kuaizhou-11 rocket

9:49 am

For reasons not yet specified, China’s new Kuaizhou-11 rocket today failed on its inaugural launch.

Many reports will say that this is a commercial rocket developed by the private company Exspace. That is not true. Like all Chinese aerospace companies, they do their work wholly under the supervision of the Chinese government.

The development of the KZ-11 began in 2015, with a maiden launch originally scheduled for 2018. The rocket is developed by China Aerospace Science and Technology Corporation (CASIC) and commercialized by the China Space Sanjiang Group Corporation (Expace).

The launch vehicle can loft a 1,500 kg payload into a Low Earth Orbit (LEO) or 1,00 kg to a 700 km sun-synchronous orbit.

The KZ-11 solid launch vehicle adopts a mobile launch platform, integrated power supply equipment, test and launch control facilities, aiming facility and temperature control facility, to carry vehicles from the technical support center to launch site, complete temperature control of payload, vehicle test and launch.

CASIC is in many ways China’s equivalent of NASA. And everything described in the last paragraph above, from solid rockets to mobile launches, are technologies developed expressly for military purposes. China will not let such things out for commercial companies to use however they wish, no matter what they claim.

Results from Yutu-2 determine “gel-like” rocks are impact melt

9:04 am

Chinese scientists have now published their analysis of the “gel-like” rocks seen by China’s Yutu-2 lunar rover back in October 2019, and have concluded that they are glasses produced from melt occurring during an impact.

The authors describe the material as a dark greenish and glistening impact melt breccia, measuring 20 inches by 6 inches (52 by 16 centimeters). These features are signs of possible presence of glasses, which are usually sourced from impact melts or from volcanic eruptions.

According to the paper, the breccia — broken fragment of minerals cemented together — was formed by impact-generated welding, cementing and agglutinating of lunar regolith and breccia. The material, they say, resembles lunar impact melt breccia samples returned by NASA’s Apollo missions. In particular, similarities with the Apollo samples designated 15466 and 70019 are noted, a comparison made earlier by lunar scientist Clive Neal at the University of Notre Dame. Sample 70019, collected by astronaut and trained geologist Harrison “Jack” Schmitt, is made of dark, broken fragments of minerals cemented together and black, shiny glass.

The results are not definitive, however. The paper notes that the analysis is limited by the fact that VNIS measurements were taken under bad illumination conditions and other factors.

This conclusion is not surprising, as the rover has been traveling through a region dominated by impact ejecta.

China announces target launch date for its Tianwen-1 Mars rover

10:51 am

The new colonial movement: According to a new report out of Singapore, China has set July 20-25 as the launch window for its Mars orbiter/lander/rover mission, dubbed Tianwen-1.

Should they meet this date, it means they will launch before Perseverance, arriving at Mars about the same time, in February 2021. And like Perseverance, this launch window closes this summer, and if they can’t meet it they will have to wait two years.

Yutu-2 travels 62 feet during 19th lunar day

10:45 am

According to the official Chinese press, Yutu-2 traveled another 62 feet during its 19th lunar day on the far side of the Moon.

I did not get that number from the article, which was written to imply falsely that the rover’s total travel distance since landing (463 meters) was what it did during this single lunar day. To get the real travel distance I took the total from the previously reported total travel distance and figured the difference.

If you want to be educated to the absolutely useless nature of a state-run press, put both links above in separate tabs and compare. You will discover that other than some very minor changes, the new news story is essentially a cut-and-paste of the previous. Which by the way is a cut-and-paste of the last few reports. They don’t even bother to make believe (like the leftist American mainstream media) that they are giving us some information. They simply don’t.

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.

China a major investor in World View

8:39 am

It appears that one of the major financial backers of the Arizona-based high-altitude balloon company World View is a Chinese investment company with close ties to the Chinese Communist Party.

World View’s long-time investors include Tencent Holdings, a Chinese tech company that operates the WeChat messaging and social media service that is among the world’s largest. And like other tech companies in China, it has close working ties to the ruling Communist Party in Beijing. Tencent has sought to expand its relations with American tech firms, a move that has raised national security concerns that the Chinese government could be surreptitiously gathering information using American technology.

Hartman [World View CEO] said that isn’t happening, noting the Pentagon’s Defense Counterintelligence Security Agency examined the company last year to ensure its work was secure from foreign interference. The agency cleared World View to handle work for the military.

Tencent has “zero access, zero input and zero control,” Hartman said.

The article at the link is focused mostly on the Democratic candidate for the Senate in Arizona, Mark Kelly, and his ties to World View with its Chinese investor. To my mind the World View links are more important, as World View under Hartman has been selling its high altitude balloons as a way to do military surveillance and reconnaissance at less cost and with more flexibility than with satellites.

Getting investment capital from China means that, despite Hartman’s reassurances, China will likely get access to this technology, either to use in its own country, or maybe even use surreptitiously in the U.S., inside a World View balloon.

As much as I really would like to see World View succeed, as long as they rely on Chinese money they should be denied any military contracts. And Kelly’s involvement as a co-founder of the company, without raising this issue himself, does suggest his focus on protecting the U.S. from foreign influence and spying is quite weak. It does indicate that he can be brought, from the highest bidder, whoever that bidder might be.
