Rocket Lab & China launch rockets

Rocket Lab and China successfully completed launches today.

Rocket Lab used its Electron rocket to put a large cubesat into the highest orbit the company has yet achieved. This was the company’s nineth successful launch, and the fifth in 2019.

China in turn used its Long March 3B rocket to place a military communications satellite into orbit.

The leaders in the 2019 launch race:

20 China
17 Russia
10 SpaceX
6 Europe (Arianespace)
5 Rocket Lab

The U.S. now leads China 21 to 20 in the national rankings.

Preparations begin for China’s next Long March 5 launch

China has apparently begun preparations for a long-delayed third and critical Long March 5 launch by the end of this year.

Two cargo transport ships left port on the Yangtze river late Friday Eastern for the northern city of Tianjin. They are expected to collect components of a third Long March 5 heavy-lift launch vehicle, which has been grounded since a 2017 launch failure.

After expected arrival Oct. 15 and subsequent loading, Yuanwang-21 and 22 ships will deliver the rocket to the island province of Hainan. Launch preparations requiring about two months will then commence at the Wenchang Satellite Launch Center.

Without this rocket, which is the world’s second most powerful after the Falcon Heavy, China cannot build its space station or launch either of its 2020 Mars orbiter or its Chang’e-5 lunar sample return mission.

The rocket’s failure on its second launch in July 2017 occurred because of an engine failure that required a major redesign. Since much of China’s space technology is initially stolen from others, it does not surprise me that they had problems. When you steal this kind of technology, rather than develop it yourself, your engineers might not fully understand it to the degree necessary to make it work.

At the same time, the track record of China’s engineers in eventually figuring out how their stolen technology works and even improving it has been very good. I would expect this December launch to be successful.

More “Free Hong Kong” protesters at NBA-Chinese exhibition games

Maybe we aren’t sheep: A group of protesters showed up at a Washington Wizards exhibition game yesterday against a Chinese basketball team with more “Free Hong Kong” signs, chanting the same throughout the game.

NBA officials however continue to kowtow to China’s demand to squelch these American protests, in America:

During the pregame singing of the Chinese national anthem, there were additional protests, with activists holding up signs and yelling, “Free Hong Kong.” One couple displaying a Tibetan flag left after being confronted by security. Yells of “Free Hong Kong” continued to ring out over the course of the game, as protesters migrated to different sections of the arena.

Security confiscated a “Free Hong Kong” sign from a group of protesters sporting the t-shirts. Later in the first quarter, the protesters displayed a smaller sign reading “Google Uyghurs,”—referring to Chinese Muslims incarcerated in state prison camps—which was also confiscated. [emphasis mine]

Meanwhile, the satirical website, the Babylon Bee, captures the stupidity and anti-Americanism of the NBA perfectly: NBA Now Requiring All Players To Stand For Chinese National Anthem, adding that “Anyone who doesn’t comply will be shot, a beloved Chinese custom that should further smooth things over with the authoritarian regime.”

Two fans removed from NBA game for holding “Free Hong Kong” signs

They’re coming for you next: Two fans were removed from an NBA exhibition game in Philadelphia (home to the Liberty Bell) yesterday for holding up “Free Hong Kong” signs.

This is a continuation of the recent story which started when the general manager of the NBA’s Houston Rockets, Daryl Morey, had tweeted support for the Hong Kong protesters. Because the NBA has many financial ties with China (including a training camp in a region in China where they also have their death camps), the NBA demanded and got an apology from that general manager, and has since been taking whatever action it can to squelch any criticism of China within or linked to the league. The removal of these two fans is part of that oppressive campaign, all aligned with this demand by China:

“We are strongly dissatisfied and we oppose [any] claim to support Morey’s right of free expression. We believe that any speech that challenges national sovereignty and social stability is not within the scope of freedom of speech,” CCTV said in its statement in Chinese, which was translated by CNBC.

What disturbs me most about this story is that it could not have happened if only the NBA had demanded it. It required the willing cooperation of the Philadelphia 76ers management, the security detail at the stadium, and the crowd surrounding these fans.

In the past all Americans would have told the Chinese to go jump in a lake. We would have laughed at these demands, even those businesses whose financial dealings with China that might be lost by taking such a stand.

If anything, Americans in the past would have suddenly started showing up at every NBA game, carrying hundreds of “Free Hong Kong” signs. At this moment I see no evidence of this happening. Americans apparently are now the sheep that dictatorships like China can nonchalantly rule, at their whim.

Chinese head in Hong Kong invokes emergency powers

Escalation: Carrie Lam, the Chinese-appointed chief executive in Hong Kong, today invoked emergency powers in her effort to stem the anti-Chinese demonstrations that have been on-going now for four months.

[P]rotesters here can now face criminal penalties of up to than $3,000 and a year’s imprisonment simply for wearing the masks they have used to defend themselves against tear gas and the possibility of arrest.

And, having invoked emergency powers, Lam is now in a position to do almost anything. As the New York Times sums it up: “Under the emergency powers, Mrs. Lam has a wide discretion to create new criminal laws and amend existing laws — all without going through the legislative process.” Newspapers can be censored or shuttered, web sites closed down, property seized, searches carried out galore, and so forth.

It appears that China is beginning the process of cracking down, and will likely do it incrementally, in the hope this will defuse the response, both by the Hong Kong population and the international community.

China to open FAST radio telescope to world

China has decided to allow astronomers worldwide to apply for time on its new FAST radio telescope, the largest such telescope in the world.

Since testing began in 2016, only Chinese scientists have been able to lead projects studying the telescope’s preliminary data. But now, observation time will be accessible to researchers from around the world, says Zhiqiang Shen, director of the Shanghai Astronomical Observatory and co-chair of the Chinese Academy of Sciences’ FAST supervisory committee.

Obviously U.S. astronomers are going to want to use this telescope. I wonder if there will be security issues. I suspect that if they only request time and then make observations, there will be no problems. However, if they need to do anything that will require the use of U.S. technology, in China, then they may find themselves violating the U.S. law that forbids any technology transfer to China.

Russia and China to team up on lunar lander/orbiter missions

Russia and China have signed an agreement to cooperate on several future lunar lander and orbiter unmanned missions.

The agreements will see cooperation in Russia’s Luna-26 orbiter spacecraft and Chang’e-7 polar landing mission, according to Roscosmos, which could involve contributions of science payloads to the respective spacecraft. Both missions are currently scheduled for the early-to-mid 2020s.

The two sides also committed to previously announced plans to create a joint lunar and deep space data center, which will consist of hubs in both Russia and China.

How they will specifically cooperate on those specific space missions was not made clear. From what I can gather, the real heart of this agreement are those joint data centers for both missions.

Yutu-2’s first close look at mysterious “gel-like” material

gel-like?
Click for full image.

Chinese scientists have released images showing their approach and first look at the mysterious “gel-like material they spotted inside a small crater using their lunar rover Yutu-2, presently exploring an area on the far side of the Moon.

The image to the right, cropped and expanded to post here, focuses on that location. As much as we might wish it, the rectangle is not the monolith from 2001, a Space Odyssey. It is merely a section where it appears they increased the exposure to see more details in the shadows. Also, as noted at the webpage:

The compressed, black-and-white shot comes from an obstacle-avoidance camera on the rover. The green, rectangular area and red circle within are suspected to be related to the field of view of the Visible and Near-Infrared Spectrometer (VNIS) instrument, rather than the subject matter itself, according to some lunar scientists.

Apparently they were unsatisfied with the data from this viewpoint, and moved the rover to get a second better view. The results from that second location however have not been released.

More delays for China’s Long March 5

Chinese officials have now admitted that the next launch of China’s biggest but troubled rocket, the Long March 5, will not occur until December 2019 at the earliest.

Moreover, the first launch of Long March 5B, the new version of the rocket developed following the Long March 5 failure on its second launch in 2017, won’t happen until 2020. This is the version they plan to use to launch their space station modules, and these delays probably thus delay start of the in-orbit assembly of their space station by two years, to 2022.

These rocket delays also threaten the launch of China’s Chang’e-5 lunar sample return mission and their first Mars orbiting mission, which has a firm summer 2020 launch window which if missed will delay the mission’s launch for two years.

These reports also for the first time officially explain the engine trouble that caused the Long March failure on its second launch in July 2017.

Addressing the causes of the failure has required a lengthy process of redesign and testing of the YF-77 liquid hydrogen-liquid oxygen propellant engines. Two YF-77 engines power the rocket’s first stage, with an oxidizer turbopump isolated as the fault behind the 2017 launch failure.

The Space News article very strangely headlines the completion of the core module for China’s space station, when the real story here is the continuing delays in getting Long March 5 off the ground. Without that rocket none of China’s big space plans can proceed. Yet the article buries this scoop many paragraphs down. I wonder why.

China’s Long March 4B launches three satellites

China yesterday used its Long March 4B rocket to launch three satellites into orbit.

This was the first Long March 4 launch since May, when the third stage of a Long March 4C rocket failed. The main payload was a remote sensing satellite with both civilian and military applications. The second satellite was to provide ocean data and weather, with the third a cubesat testing new space communications and the use of a drag sail for de-orbiting.

Yutu-2 travels almost 300 meters on ninth lunar day

According to a story today in official Chinese state-run media, Yutu-2 traveled another 284.99 meters during its ninth lunar day on the surface of the Moon, and has now been placed in hibernation in order to survive the long lunar night.

The story provides no further information, including saying nothing about the strange and unusual material the rover supposedly spotted during this time period.

China withdraws extradition bill that sparked Hong Kong protests

The Hong Kong government today announced that it is withdrawing the extradition bill demanded by China that sparked Hong Kong protests.

Carrie Lam, Hong Kong’s chief executive, said Wednesday that the government would withdraw a contentious extradition bill that ignited months of protests in the city, moving to quell the worst political crisis since the former British colony returned to Chinese control 22 years ago.

The move eliminates a major objection among protesters, but it was unclear if it would be enough to bring an end to intensifying demonstrations, which are now driven by multiple grievances with the government.

“Incidents over these past two months have shocked and saddened Hong Kong people,” she said in an eight-minute televised statement broadcast shortly before 6 p.m. “We are all very anxious about Hong Kong, our home. We all hope to find a way out of the current impasse and unsettling times.”

Her decision comes as the protests near their three-month mark and show little sign of abating, roiling a city known for its orderliness and hurting its economy.

The article suggests that the protests will still go on, that the “genie is out of the bottle.” I am not so sure.

Regardless, what this means is that, as of now, China is admitting that its effort to eliminate Hong Kong’s democratic systems and fold it completely into the communist power structure of the mainland has failed. This does not mean that China will stop trying, merely that they will now pause in this effort.

Police ramp up violence against Hong Kong protesters today

This weekend’s Hong Kong protests against China’s rule resulted in increased violence by the police against the protesters.

In the evening, clashes between police and demonstrators broke the peaceful rhythm in the afternoon rallies, repeating the pattern of past weekend protests. Police deployed water cannon trucks several times, unleashing blue-dyed water that would make it easier for police to identify frontline protesters. Police chased down protesters and beat them up with batons, injuring multiple people in the head. One person was injured in the left eye, reportedly by a police-fired projectile.

On Hennessy Road, where many protesters had gathered, police fired multiple rounds of tear gas and sponge grenades. Police also confirmed that they fired two live rounds near Victoria Park. There were no reported injuries in the area. It is unclear why police decided to deploy their service weapons at the time.

Toward midnight, violence spread into subway stations in Kowloon district. At the Prince Edward metro station and several other stations in Kowloon, police charged into the station and into train cars, deploying pepper spray and beating their batons. Officers arrested at least a dozen individuals. Several unarmed passengers were seen bleeding from injuries.

More details at the link. It appears that the protests were peaceful for most of the day, until the police decided to move in and try to shut them down.

Has Yutu-2 found something unusual?

According to Chinese sources, China’s lunar rover Yutu-2 has spotted something unexpected and unusual on the surface of the far side of the Moon.

On July 28, the Chang’e-4 team was preparing to power Yutu-2 down for its usual midday ‘nap’ to protect the rover from high temperatures and radiation from the sun high in the sky. A team member checking images from the rover’s main camera spotted a small crater that seemed to contain material with a color and luster unlike that of the surrounding lunar surface.

The drive team, excited by the discovery, called in their lunar scientists. Together, the teams decided to postpone Yutu-2’s plans to continue west and instead ordered the rover to check out the strange material. With the help of obstacle-avoidance cameras, Yutu-2 carefully approached the crater and then targeted the unusually colored material and its surroundings. The rover examined both areas with its Visible and Near-Infrared Spectrometer (VNIS), which detects light that is scattered or reflected off materials to reveal their makeup.

VNIS is the same instrument that detected tantalizing evidence of material originating from the lunar mantle in the regolith of Von Kármán crater, a discovery Chinese scientists announced in May.

So far, mission scientists haven’t offered any indication as to the nature of the colored substance and have said only that it is “gel-like” and has an “unusual color.” One possible explanation, outside researchers suggested, is that the substance is melt glass created from meteorites striking the surface of the moon.

The report is at present too vague to really tell us anything. What I predict is that this discovery will almost certainly not be as strange or alien as this report makes it sound.

China launches two smallsats

Using its Kuaizhou-1A solid rocket, China’s pseudo-private company ExSpace launched two smallsats into orbit yesterday.

This rocket, using technology developed for the military, including a mobile launch platform, is designed to compete directly with Rocket Lab and the other western private smallsat rockets trying to come on line right now. Its development appears to have been wholly funded by the Chinese government, which revealed after the launch that they plan between 8 and 9 more launches before the end of the year.

Hong Kong arrests three prominent protest leaders

In a sign that China has no intention of compromising with the protesters in Hong Kong, authorities there today arrested three of the most high-profile leaders of the protest movement.

Two were active in protests in 2014.

Joshua Wong and Agnes Chow, who rose to eminence as the student leaders of pro-democracy demonstrations in 2014, were detained Friday, ahead of what is expected to be a tense weekend in the city. Authorities banned a march planned for Saturday, and warned they would use force and possibly arrest those who defy the order.

Police said Wong and Chow face charges of participating in an unauthorized assembly and inciting others to participate in an unapproved assembly, while Wong faces an additional charge of organizing an unapproved assembly, in relation to a June 21 protest at police headquarters. Both were released on bail Friday. …

The sweep came ahead of a sensitive political anniversary in the semiautonomous Chinese territory. This Saturday marks five years since Beijing announced an electoral-reform plan that denied Hong Kong free elections — a decision that triggered 79 days of pro-democracy protests.

More here, including information about other arrests in addition to the three above.

I’m not sure China’s actions here are going to prevent demonstrations tomorrow. For example,

The bespectacled Wong, who was 17 when he became the face of the student-led civil disobedience movement in 2014 that blocked major roads for 79 days, has not been a prominent figure in the latest protests, which have no identifiable leaders.

The same thing applies to the others who were arrested. There doesn’t appear to be anyone in particular running these protests, which means arresting a few scapegoats and banning further demonstrations will probably not work. We shall find out this weekend.

China’s FAST radio telescope discovers 93 new pulsars

Hong Kong police fire water cannons, gunshot, against protesters

The first gunshot and use of water cannons by Hong Kong police occurred today against protests opposed to increased Chinese rule over that former British colony.

Earlier Sunday, after thousands of people marched peacefully in pouring rain, a group of hardcore protesters erected makeshift roadblocks and threw bricks and Molotov cocktails at riot police. After firing tear gas in an attempt to dispers the crowds, police drove water cannon vehicles onto the streets for the first time during the protests, unfurling signs warning demonstrators they would deploy the jets if they did not leave. The jets were later fired down from the moving trucks down a road towards a crowd of protesters who ran away.

There were no immediate reports of injuries.

There is also no additional information about the gunshot, though it appears it caused no injuries.

China successfully tests navigation in space using pulsars

Using the X-ray space telescope Insight it launched in 2017, China has successfully tested an autonomous navigation system using pulsars.

The time interval of two adjacent pulses emitted by the pulsar is constant. If a spacecraft moves toward the pulsar, the received pulse interval will be shortened, and vise versa. Thus the observed pulse profile will change as the spacecraft moves in space. The relative arrival times of pulses also indicate the relative position of the spacecraft with respect to the pulsar. Therefore, by analyzing the characteristics of the pulsar signals received by the spacecraft, the three-dimensional position and velocity of the spacecraft can be determined, Zheng explained.

From Aug. 31 to Sept. 5, 2017, Insight observed the Crab pulsar for about five days to test the feasibility of pulsar navigation. The research team had also proposed an algorithm for X-ray pulsar navigation, according to Zhang Shuangnan, lead scientist of the Insight space telescope.

The research team further improved the algorithm and applied it in the processing of the observation data of the three detectors onboard Insight. The satellite’s orbit was determined successfully, with the positioning accuracy within 10 km, comparable to that of a similar experiment conducted on the International Space Station, Zhang said.

This is not the first such test. U.S. scientists did something similar using an X-ray telescope on ISS in 2017.

Rocket Lab & China launch satellites

Both Rocket Lab and China today launched rockets to put satellites into orbit, though it is as yet still unclear whether the Chinese launch was successful.

Rocket Lab successfully placed four smallsats into orbit. It was the company’s eightth consecutive successful launch, continuing its perfect launch record.

More important, the company now has completed four launches in 2019. Their goal, announced early this year, was to achieve a monthly pace by summer, then ramp up to twice a month by the end of the year. So far they are not quite meeting that goal, averaging one launch every 1.5 months (March, May, June, August). Still, this record is quite impressive, considering they are a very new and very small private company that it now is beginning to match or exceed the launch pace of other nations (India) as well as well-established companies (ULA).

China’s Long March 3B launched a civilian communications satellite, but according to the story at the link, “the usual announcement of a successful separation has yet to published by Chinese State media.” For the purposes of the launch standings, I will assume at the moment that this was a successful launch, but will revise this post should we learn the satellite did not reach orbit. Update: It appears the launch was successful, but the satellite is having problems. This would mean the launch counts below.

1.7 million protest China in Hong Kong

A gigantic protest — estimated to be 1.7 million people strong — against China’s effort to limit freedoms in Hong Kong filled that city’s streets today, despite pouring rain and in defiance of police orders.

Sunday’s action, billed as a return to the peaceful origins of the leaderless protest movement, drew more than 1.7 million people, making it one of the largest rallies since the protests began about three months ago, according to organisers the Civil Human Rights Front.

It ended a weekend of protests that, as of early Monday, saw no major confrontations with police for the first time in weeks.

Hong Kong has always been China’s equivalent of West Berlin in East Germany, a leak in the monolith communist state that in the long run can only make that communist state unsustainable. Khrushchev temporarily solved this problem (for about forty years) by building a wall around West Berlin that blocked East Germans from entering it. Khrushchev’s act eventually failed, and when it did it took down the Soviet Union.

What will China do? In 1989 the Chinese communists shut down all opposition, far more brutally than Khrushchev, killing thousands in Tiananmen Square. Can the do the same now in Hong Kong?

At the moment this is very unclear.

China launches three satellites on new rocket

China today successfully completed the first orbital launch of its privately-funded but government-built smallsat Smart Dragon rocket, putting three smallsats into orbit.

From the Chinese state press:

The rocket, developed by the China Rocket Co. Ltd. affiliated to the China Academy of Launch Vehicle Technology (CALVT), blasted off from the Jiuquan Satellite Launch Center in northwest China at 12:11 p.m. (Beijing Time).

The three satellites, respectively developed by three Beijing-based companies, will be used for remote sensing services, communication and Internet of Things.

Different from the carrier rockets of the Long March family, the new Dragon series is developed in a commercial mode to meet the market demand of launching small commercial satellites, said Wang Xiaojun, head of CALVT.

What they mean by “a commercial mode” is that the funding comes from private Chinese investors who hope to make money from the rocket’s launches. However, this is not a private operation by any means, since the rocket is owned and built by a government entity and uses military solid motors.

From an American perspective, this Chinese attempt to create a commercial launch industry using private funds but tight government supervision and control is very puzzling. This government company is now competing directly with other Chinese launch companies that are, at least superficially, owned and run by private corporations (though also supervised closely by the government). How the Chinese government prevents its government agencies from putting their thumbs on the scale to favor one over the other I do not understand.

Hong Kong airport reopens as protesters retreat

It appears the actions by Chinese riot police yesterday has caused the airport protesters in Hong Kong to back off and allow the airport to reopen.

Most of the protesters left the airport Tuesday after riot police tried to enter the terminal, fighting with demonstrators who barricaded entrances with luggage carts. The brief clash led to several injuries.

The violence included protesters beating up at least two men they suspected of being undercover Chinese agents. Airport security appeared unable to control the crowd, and paramedics later took both men away. Police have acknowledged using “decoy” officers, and some protesters over the weekend were seen being arrested by men dressed like demonstrators — in black and wearing face masks.

Hu Xijin, editor-in-chief of the Global Times, identified one of the men as a journalist at the nationalistic Chinese tabloid. “Fu Guohao, reporter of GT website is being seized by demonstrators at HK airport,” Hu wrote on his Twitter account. “I affirm this man being tied in this video is the reporter himself. He has no other task except for reporting.”

The protesters apologized that some of them had become “easily agitated and overreacted.” On posters, the demonstrators said they have been “riddled with paranoia and rage” after discovering undercover police officers in their ranks.

Meanwhile the article describes other clashes elsewhere in Hong Kong. The conflict in Hong Kong does not appear to be over, by any means.

Riot police attack Hong Kong airport protesters

Riot police today attacked the Hong Kong airport protesters, storming into their midst with batons and pepper spray.

CNN International reported, following the police operation that reporters witnessed at least four arrests and that officers appeared to be targeting specific people. To get through the protesters, police used pepper spray and batons to push back the crowd. According to an official statement from Hong Kong police, airport officials requested that the riot officers enter the airport to rescue a man who protesters had apprehended and accused of being an undercover police officer. The South China Morning Post also reported that the airport received a court injunction requesting police remove the protesters from the premises, though Hong Kong police did not issue an official statement to that effect and officers left without clearing out every protester.

Pro-democracy protesters shut down the airport Tuesday for the second day in a row, forcing administrators to cancel all flights, in a bid to get the China-controlled Hong Kong government to listen to their demands. Some protesters appeared to panic and target others suspected of working for the communist government after officials admitted this weekend that officers had dressed up as protesters to infiltrate the marches.

So far this attack today does not appear to be an effort to shut the protest down with violence. It appears that after extracting two men, possibly pro-China reporters, the police retreated, though the authorities are now limiting access to the airport, probably with the goal of starving the protest with a lack of new supporters.

A very sad messy situation. The Chinese want to impose its tyranny on Hong Kong. Hong Kong’s citizens want to remain free. The result are street protests that can only turn violent, one way or the other, because China’s government is very unlikely to back down.
