JIUQUAN, May 8 (Xinhua) — The return capsule of the trial version of China’s new-generation manned spaceship successfully returned to the Dongfeng landing site in north China’s Inner Mongolia Autonomous Region at 1:49 p.m. (Beijing Time) Friday, according to the China Manned Space Agency (CMSA).

The test was a complete success, the agency said.

Following the instructions from the Beijing Aerospace Control Center, the experimental spaceship applied the brake and entered the return orbit at 12:21 p.m., and its return capsule separated with its service capsule at 1:33 p.m.

After it re-entered the atmosphere and reached the designated altitude, the two deceleration parachutes and three main parachutes on the return capsule opened, slowing the flight speed of the spacecraft to the driving speed of an urban vehicle. Before touching down, its six airbags were deployed and inflated to help it land softly, according to the China Aerospace Science and Technology Corporation (CASC).

At 1:49 p.m., the return capsule landed safely. The search team found it in a timely manner and confirmed that the capsule structure was intact.

China launched the trial version of the new spaceship without a crew by the Long March-5B carrier rocket from the Wenchang Space Launch Center in southern China’s island province of Hainan on Tuesday.

The experimental spaceship flew in orbit for two days and 19 hours, during which it carried out a series of space science and technology experiments, including space 3D printing, said CMSA.

It also tested key technologies including the heat shielding and control during its re-entry into the atmosphere, as well as multi-parachute recovery and partial reuse, CMSA said.

The new-generation manned spaceship is an advanced space transport vehicle adapted to multiple tasks. It can be used not only in low-Earth orbit missions to support the construction of China’s space station but also for deep-space exploration, such as manned lunar exploration, CMSA said.

INNOVATIVE DESIGN

Developed by the China Academy of Space Technology (CAST) under the CASC, the test spaceship is nearly 9 meters tall and about 4.5 meters at its widest point. It weighs more than 20 tonnes.

Different from the three-capsule structure of Shenzhou spaceships currently in use, the new spacecraft comprises a return capsule, which is the command center and the living place for astronauts, and a service capsule, which provides power and energy, according to the CAST.

In Shenzhou spaceships, astronauts have to go back and forth between two smaller capsules for life and work. The return capsule of the new ship has a larger sealed space. In the future, it can be partitioned to set up a work area, entertainment area, dining area and bathroom, so as to provide a more comfortable living environment for astronauts.

The capsule can also be equipped with large screens for entertainment and display instruments connected with wearable devices so that astronauts can enjoy colorful space travel and be kept informed of the ship’s conditions.

The new design can also shorten the spaceship development cycle and cut the development costs, which will show a significant advantage in the future with space exploration activities more and more frequent, said Yang Qing, a designer of the experimental spaceship with the CAST.

Researchers have integrated the power supply, propulsion, fuel resources and other subsystems all into the service capsule, so that the same return capsule can be paired with different service capsules to meet variant needs of multiple tasks, including the space station operation and subsequent manned space missions.

The return capsule is designed to be reusable. Star sensors, computers and other high-value equipment have been moved from the service capsule to the return capsule so that they can be recycled after returning to Earth.

The return capsule is wrapped in two items of “clothing.” The inner layer is made of new metal materials and acts as a “wall” around the “driving cab.” The outer layer is made of a new type of light heat-resistant material, which can withstand ablation of thousands of degrees Celsius in the process of re-entry and return, according to Guo Bin, a member of the development team of the experimental spaceship with the CAST.

The new heat-resistant materials, adopted for the first time, are lighter than the traditional materials by 30 percent but have a greater heat-shielding capacity. They are also replaceable to improve the reusable rate of the capsule, Guo said.

The return capsule also uses a non-toxic propulsion system, consisting of 12 monopropellant-powered engines with the largest thrust in the world, which are applied for the first time in China to make the capsule safer and reusable, Guo said.

NEW DREAM SHIP

China started its manned space program in 1992 and has so far witnessed 11 astronauts enter space and return safely.

However, when the country eyes on the moon and the deeper space, Shenzhou spaceships and Tianzhou cargo spacecraft are no longer enough to meet its greater dreams.

Engineers started to create the new test spaceship from January 2017 and completed it in just three years after making many technological breakthroughs.

It can transport both people and goods, greatly expanding the capability and application of China’s manned spacecraft, Yang said.

It can be called a “space bus” as it is able to send six to seven astronauts at a time into low-Earth orbit. It can also be converted into a “space truck” according to new mission requirements, delivering a large number of supplies to the space station or bringing back space engineers’ test samples to Earth, Yang said.

The reliability, safety, comfort, economy and intelligence of the new spaceship have been greatly improved.

When in orbit, the ship’s “brain” — the guidance, navigation and control systems — can control the flight independently without relying on instructions from the ground. Through the combination of high-performance computers and sensors, the ship can fulfill emergency orbit entry, orbit raising and lift control autonomously, enabling it to cope with various emergencies quickly and calmly.

If a “health problem” occurs, the new spaceship can make a diagnosis itself through its intelligent system to locate the lesion and remove it temporarily or permanently. It will then share the work of the malfunctioning part by optimizing and recombining the functions of other parts, which can greatly simplify the ground control and support work.

In addition to the non-toxic monopropellant-powered engines, the new spacecraft adopts a series of advanced technologies, including the distributed integrated electronic system, solar cells with high conversion efficiency and multi-terminal human-computer interaction system, which improve its overall performance by leaps and bounds.

The engineers also installed a data acquisition system in the test spaceship, which will help provide scientific reference for the development and optimization of the follow-on versions of the new spaceship.

“The new and old spaceships will compliment each other. Just as trucks, buses and vans are all available on the road, there should be more transport means between space and Earth, and the new ship will enrich the selections,” Yang said.

Coronavirus latest: more than 21,000 dead as UN warns of threat to ‘whole of humanity’

  • US$2 trillion rescue package passes US Senate, heads to House
  • Malaysia’s king and queen in ‘self-quarantine’ after staff test positive

More than three billion people are living under lockdown measures as soaring death tolls in Europe and the US underlined a United Nations warning that the coronavirus, which has now infected nearly half a million people globally, threatens all of humanity.

The global death toll from the virus now stands at more than 21,000, with Spain joining Italy in seeing its number of fatalities overtake China, where the virus first emerged just three months ago.

“Covid-19 is threatening the whole of humanity – and the whole of humanity must fight back,” UN Secretary General Antonio Guterres said, launching an appeal for US$2 billion to help the world’s poor.

“Global action and solidarity are crucial. Individual country responses are not going to be enough.”

The G20 major economies will hold an emergency videoconference on Thursday to discuss a global response to the crisis, as will the 27 leaders of the European Union, the outbreak’s new epicentre.

The economic damage of the virus – and the lockdowns – could also be devastating, with fears of a worldwide recession worse than the financial meltdown more than a decade ago.

Here are the developments:

US$2 trillion rescue package passes US Senate

The US Senate passed the nation’s largest-ever rescue package late Wednesday, a US$2 trillion lifeline to suffering Americans, depleted hospitals and an economy all ravaged by a rapidly spreading coronavirus crisis.

The monster deal thrashed out between Republicans, Democrats and the White House includes cash payments to American taxpayers and several hundred billion dollars in grants and loans to small businesses and core industries. It also buttresses hospitals desperately in need of medical equipment and expands unemployment benefits.

The measure cleared the Senate by an overwhelming majority and was headed next to the House of Representatives, which must also pass it before it goes to President Donald Trump for his signature.

US President Donald Trump has voiced hope the US will be “raring to go” by mid-April, but his optimism appeared to stand almost alone among world leaders.

Unemployment benefit filings by Americans workers to surge to 3.3 million last week – the highest number ever recorded, the Labour Department reported on Thursday.

The normally routine report is at the front lines of the economic crisis caused by the outbreak, which has forced widespread closures of restaurants, shops and hotels, and brought airline travel to a virtual halt, prompting the stunning increase in people filing for benefits nationwide in the week ending March 21.

Nearly every state cited Covid-19 for the jump in initial jobless claims, with heavy impacts in food services, accommodation, entertainment and recreation, health care and transport, the report said.

Malaysia’s king and queen in quarantine after staff test positive

The official residence of Malaysia’s monarchy on Thursday confirmed seven of its staff have tested positive for Covid-19 and are currently receiving treatment at the Kuala Lumpur Hospital.

Malaysia’s king, Sultan Abdullah Sultan Ahmad Shah and queen, Tunku Azizah, have also been tested, but their results showed a clean bill of health, a spokesman for the Istana Negara said in a statement.

“Nevertheless, Their Majesties are now observing a 14-day self-quarantine, starting yesterday, ” he said.

Meanwhile, Prime Minister Muhyiddin Yassin, along with all federal ministers and their deputies, announced they will take a two-month pay cut, with the savings to be donated to Putrajaya’s Covid-19 fund.

The Prime Minister’s Office said the decision was made during a cabinet meeting and showed the government’s sincerity in helping those affected by the pandemic.

“The Covid-19 fund was launched on March 11 as part of the government’s efforts to help those who were affected by the disease outbreak,” the office said, adding that 8.5 million ringgit (US$1.97 million) has been collected, including government grants.

Malaysia on Wednesday announced a two-week extension of a national lockdown as part of stepped-up measures to contain the coronavirus outbreak.

The “movement control order,” which requires people to stay home and was originally set to expire on March 31, will now continue until April 14.

Russia to ground international flights

Russia will halt all international flights from midnight on Friday under a government decree listing new measures against the coronavirus outbreak.
The decree published on Thursday orders aviation authorities to halt all regular and charter flights, with the exception of special flights evacuating Russian citizens from abroad.
The announcement came after Russia on Wednesday recorded its biggest daily spike in confirmed coronavirus infections so far, with 163 new cases for a total of 658 across the country.
Denis Protsenko, head doctor of Moscow’s new hospital treating coronavirus patients, told President Vladimir Putin that Russia needed to be ready for an “Italian scenario”, referring to what is now the hardest-hit country in the world in terms of deaths.

Singapore boosts stimulus package to 11 per cent of GDP

Singapore reported 52 new coronavirus cases on Thursday, taking its tally to 683 infections.

The health ministry said that out of the 52, 28 were imported while 24 were locally transmitted.

The city state earlier on Thursday unveiled more than $30 billion in new measures to help businesses and households fight the coronavirus pandemic that threatens to push the bellwether economy into a deep recession.

Drawing on national reserves for the first time since the global financial crisis to support an economy heading for recession, the additional spending will push up the government’s virus-related relief to almost S$55 billion, or 11 per cent of gross domestic product, Finance Minister Heng Swee Keat said in a speech in parliament Thursday. It also will widen the budget deficit for the financial year starting April 1 to 7.9 per cent of GDP, from a previous target of 2.1 per cent.

“This extraordinary situation calls for extraordinary measures,” Heng said. “We have saved up for a rainy day. The Covid-19 pandemic is already a mighty storm, and is still growing.”

Imported cases rise in China

Mainland China reported a second consecutive day of no new local coronavirus infections as the epicentre of the epidemic Hubei province opened its borders, but imported cases rose as Beijing ramped up controls to prevent a resurgence of infections.

A total of 67 new cases were reported as of end-Wednesday, up from 47 a day earlier, all of which were imported, China’s National Health Commission said in a statement on Thursday.

The total number of cases now stands at 81,285.

The commission reported a total of 3,287 deaths at the end of Wednesday, up six from the previous day.

All of the new patients were travellers who came to China from overseas, with the mainland reporting no locally transmitted infections on Wednesday.

Fearing a new wave of infections from imported cases, authorities have ramped up quarantine and screening measures in other major cities including Beijing, where any travellers arriving from overseas must submit to centralised quarantine.

Coronavirus could become seasonal

There is a strong chance the new coronavirus could return in seasonal cycles, a senior US scientist said Wednesday, underscoring the urgent need to find a vaccine and effective treatments.

Anthony Fauci, who leads research into infectious diseases at the National Institutes of Health, told a briefing the virus was beginning to take root in the southern hemisphere, where winter is on its way.

“What we’re starting to see now … in southern Africa and in the southern hemisphere countries, is that we’re having cases that are appearing as they go into their winter season,” he said.

“And if, in fact, they have a substantial outbreak, it will be inevitable that we need to be prepared that we’ll get a cycle around the second time.

“It totally emphasises the need to do what we’re doing in developing a vaccine, testing it quickly and trying to get it ready so that we’ll have a vaccine available for that next cycle.”

There are currently two vaccines that have entered human trials -one in the US and one in China – and they could be a year to a year-and-a-half away from deployment.

Spain extends emergency by two weeks

Spain’s parliament has voted in favour of the government’s request to extend the state of emergency by two weeks that has allowed it to apply a national lockdown in hopes of stemming its coronavirus outbreak.

The parliamentary endorsement will allow the government to extend the strict stay-at-home rules and business closings for a full month. The government declared a state of emergency on March 14. It will now last until April 11.

Spain’s government solicited the two-week extension after deaths and infections from the Covid-19 virus have skyrocketed in recent days. Spain 47,600 total cases. Its 3,434 deaths only trail Italy’s death toll as the hardest-hit countries in the world.

The parliament met with fewer than 50 of its 350 members in the chamber, with the rest voting from home to reduce the risk of contagion.

Greece locks down Muslim towns

Greek authorities have quarantined a cluster of Muslim-majority towns and villages in the country’s northeast after several cases and a death from the new coronavirus in the area.

The area in Xanthi prefecture was placed in lockdown as of Wednesday evening as nine people in the region overall have tested positive for the virus over the past six days, civil protection deputy minister Nikos Hardalias told reporters.

“All residents have been temporarily confined at home. No exceptions are allowed,” Hardalias said.

The centre of the outbreak appears to be the small Pomak town of Ehinos, a community of about 2,500.

“Ehinos residents will be provided with food and medicine,” Hardalias said.

Police were deployed on Thursday on a bridge leading into town to enforce the lockdown, television footage showed.

One 72-year-old Ehinos man has died from the virus, local mayor Ridvan Deli Huseyin told Antenna television.

“It’s better to take some measures now than to cry about this later,” said Huseyin, the mayor of the local administrative centre of Miki.

The Pomaks are a Muslim group of Slavic origin who live mainly in neighbouring Bulgaria.

They make up part of Greece’s roughly 110,000-strong Muslim minority in the country’s northeast bordering Turkey.

Many of them work as migrant industrial workers in other European countries.

Colombia goes into lockdown, Chile extends schools closures

Countries across Latin America tightened measures on Wednesday to halt the spread of the deadly novel coronavirus, with more lockdowns, border closings and school closures as well as increased aid to the region’s poorest.

As cases of Covid-19 cases continue to rise – more than 7,400 and 123 deaths up to now – Bolivia and Colombia became the latest countries to impose a total lockdown, while Chile extended its schools closures until the end of April.

Brazil’s President Jair Bolsonaro has warned of possible “chaos” and the “looting” of supermarkets if state shutdowns ordered by the governors of Sao Paulo and Rio de Janeiro aren’t ended.

Bolsonaro, who has repeatedly scoffed at the severity of the deadly pandemic, had previously criticised the closing of schools and businesses in Sao Paulo and Rio states, two of the country’s most populous states.

Germany ramps up testing, approves huge bailout

Germany has boosted its coronavirus test rate to 500,000 a week, Christian Drosten, who heads the Institute of Virology at Berlin’s Charite University Hospital, said on Thursday, adding that early detection has been key in keeping the country’s death rate relatively low.

Drosten also highlighted Germany’s dense network of laboratories spread across its territory as a factor contributing to early detection.

The news came after Chancellor Angela Merkel’s government secured emergency spending, unlocking a historic rescue package designed to cushion the blow of the coronavirus pandemic.

A majority of lawmakers in the Bundestag voted on Wednesday to allow additional borrowing to combat the crisis, according to the legislature’s president. The Bundesrat, or upper house of parliament, will vote on Friday.

The extraordinary authorisation is part of a packet of legislation aimed at protecting German jobs and businesses. The new borrowing of €156 billion (US$169 billion) is equivalent to half of the country’s normal annual spending.

The country, which tightened lockdown measures this week, has about 32,700 cases and more than 150 deaths.

Ukraine declares ‘emergency situation’

Ukraine on Wednesday declared a month-long “emergency situation” to slow the coronavirus outbreak, as the number of confirmed cases jumped to 113.

Ukraine has already closed schools, universities and public spaces to stem the spread of the disease, but the measures were due to expire at the beginning of April.

The emergency situation announced on Wednesday effectively extends existing measures for 30 days until April 24, a government spokesperson said.

“We are extending quarantine and imposing an emergency situation in Ukraine,” Prime Minister Denys Shmygal said.

Unlike an official state of emergency, the initiative announced by the prime minister does not have to be rubber stamped by both the parliament and president. Ukraine has confirmed 113 cases of Covid-19 and four deaths, according to official statistics.

Mexican governor says poor are ‘immune’

The governor of a state in central Mexico is arguing that the poor are “immune” to the new coronavirus, even as the federal government suspends all non-essential government activities beginning Thursday in a bid to prevent the spread of the virus.

Puebla Governor Miguel Barbosa’s comment on Wednesday was apparently partly a response to indications that the wealthy have made up a significant percentage of Mexicans infected to date, including some prominent business executives.

Officials say three-quarters of Mexico’s 475 confirmed cases are related to international travel, and the poor do not make many international trips. Some people apparently caught the virus on ski trips to Italy or the United States. The country has seen six deaths so far.

“The majority are wealthy people. If you are rich, you are at risk. If you are poor, no,” Barbosa said of the coronavirus. “We poor people, we are immune.”

Barbosa also appeared to be playing on an old stereotype held by some Mexicans that poor sanitation standards may have strengthened their immune systems by exposing them to bacteria or other bugs.

There is no scientific evidence to suggest the poor are in any way immune to the virus that is causing Covid-19 disease around the world.

Japan belatedly bans entry from Europe, Iran

Japanese Prime Minister Shinzo Abe has established a task force under the country’s revised emergency law to deal with the global rise in coronavirus infections and deaths.

In Tokyo on Thursday, Abe said it was necessary for people to act as one to overcome what can be described as a national crisis.

Japan will ban entry from 21 European countries as well as Iran, to take effect from Friday, he added.

The country has already begun asking visitors and its nationals arriving from some countries in Southeast Asia, the Middle East and Africa to self-quarantine for 14 days.

Arrivals from a total of seven Southeast Asian countries and four in the Middle East and Africa are also asked to refrain from using public transport.

Similar steps are in place for visitors from China, South Korea, most of Europe and the United States.

Malaysia to lock down two communities to curb spread

Malaysia on Thursday announced that 3,570 residents in two communities in the country’s south will be placed under complete lockdown due to their high coronavirus infection rates.

Defence Minister Ismail Sabri Yaakob said in a statement that the residents in Kluang district of Johor state are banned from leaving home for two weeks beginning Friday, to enable the health authorities to conduct door-to-door screening.

The tough measure was taken after 73 per cent of the 83 infection cases found in the district were traced to the two small communities of Kampung Dato Ibrahim Majid and Bandar Baru Dato Ibrahim Majid.

Ismail said the residents cannot leave home, not even to buy food, as the welfare department will supply them with two weeks’ worth of food. All businesses must close and all access into the two areas will be sealed. The police and army have been deployed to ensure compliance.

Australia scraps haircut time limit

The Australian government scrapped a time limit on haircuts following a backlash.

The government had imposed a rule on hairdressers and barbers on Tuesday that haircuts should take less than 30 minutes, as part of social distancing restrictions to deal with the coronavirus outbreak.

The restriction put around 40,000 hairdressers at risk, the Australian Hairdressing Council said in response.

“This decision is outrageous,” the council’s chief executive Sandy Chong said in a statement.

“Whilst many barbers can do a male haircut within that time frame, it really isn’t feasible for a majority of hairdressing salons.”

Australian Prime Minister Scott Morrison issued a statement Thursday saying the policy would be reversed with immediate effect.

But salons and barbers must still strictly observe new rules that there may only be one person per four square metres within the premises, Morrison said.

India unveils US$22.6 billion stimulus package

India’s government announced a 1.7 trillion rupee (US$22.6 billion) stimulus package, as it stepped up its response to the coronavirus pandemic.

The measures will include cash transfers as well as steps on food security, Finance Minister Nirmala Sitharaman said in New Delhi on Thursday, adding that the package will benefit migrant workers.

Asia’s third-largest economy joins countries from the US to Germany that have pledged spending to contain the economic fallout of the pandemic. India is on a total lockdown for three weeks from Wednesday in the world’s biggest isolation effort, as Prime Minister Narendra Modi seeks to prevent the virus from spreading locally.

The government will also provide an insurance cover of 5 million rupees to medical workers, Sitharaman said.

Pilot shortages could ground China’s plans to develop combat-ready carrier fleet

  • The country’s second aircraft carrier, the Shandong, officially entered service this month, but bottlenecks in training could hamper the navy’s effectiveness
  • Plans to build and launch more modern warships mean the need for fully trained pilots will only grow

A shortage of naval pilots is holding back Beijing’s ambitions to develop a truly combat-ready fleet, military analysts have said.

China officially commissioned its second aircraft carrier the Shandong last week, which means it will need at least 70 pilots, along with more supporting flight officers.

However, plans to further expand its fleet to five or six carriers – as well as the more advanced technology that will be used on these vessels – mean the need to train more pilots will become more urgent in the future.

Chinese President Xi Jinping has initiated a sweeping modernisation drive across all branches of the People’s Liberation Army and said “the need to build up a strong navy has never been more pressing”.

But Collin Koh, a research fellow at the S Rajaratnam School of International Studies at Singapore’s Nanyang Technological University, said there was a bottleneck in the recruitment and training of naval pilots.

“The implications of carrier-borne aviation are still relatively unfamiliar to the PLA, especially when there’s an urge to scale up training tempo and recruitment in order to fulfil the top directives of building a viable carrier programme,” he said.

China’s training programme for all military pilots is still developing – particularly when it comes to the naval aviation arm, which was only founded in May 2013.

China’s new carrier set to have smaller jet force than expected

20 Dec 2019

China’s first aircraft carrier, the Liaoning, was commissioned in September 2012, but the first successful fighter landing on the ship did not happen until two months later.

The first successful night landing was not reported by state media until May 2018, almost four years later.

It appears to have taken even longer to fully train helicopter pilots, with the first successful day landing taking place in November 2018, according to China’s Naval Aviation University, and the first night landing in June this year.

The training programme has also been marred by a string of fatal accidents along the way, although Koh said these had been unreported to avoid deterring prospective recruits.

Days after China marked the 70th anniversary of the foundation of the People’s Republic with a huge military parade in Beijing on October 1, three airmen were killed when a transport helicopter crashed in central Henan province.

Just eight days later there was another crash on the Tibetan Plateau, where a J-10 fighter jet on a low-altitude flying drill crashed into a mountain. The pilot was reported to have survived.

“The attrition rate of carrier-borne pilot training, including those who might have been injured or killed in the line of duty, isn’t that well publicised by the PLA,” said Koh.

Li Jie, another Beijing-based military expert, said although the navy is short of pilots now, the problem could be solved within two to three years.
“The insufficient number of carrier-borne warplanes and the substantial training needed for a qualified naval pilot are the two main reasons why China is so short of pilots now. But as China places more and more emphasis on the education and training of the pilots, the problem will be gradually ironed out, ” said Li.

The Naval Aviation University, which is responsible for the training of future naval pilots, has been working with three of the country’s leading universities – Peking, Tsinghua and Beihang – to identify and recruit future pilots.

The authorities have also set up Naval Aviation Experimental Classes in high schools across the country. Each class recruits 50 students, who enjoy a national subsidy and will be put in a priority list to be admitted as a naval pilot.

A woman who threw coins onto the parking apron at an airport in southwest China in the superstitious belief it might cure her cousin’s baby’s diarrhoea was instead fined 200 yuan (US$28), local media reported.
The incident happened on September 5, as the woman, surnamed Wang, and a group of her relatives arrived in Xichang, Sichuan province, after flying from Nanchang, Jiangxi province, to attend a family wedding, the Chengdu Business News reported on Friday.
Wang, 23, dropped the coins through the gap between the aircraft and the jet bridge as she and her family were disembarking.
Police said the medical student was shocked when she realised the trouble she had caused. Photo: Weibo

Although no one spotted what she had done at the time, airport workers later found three coins on the ground while conducting a security check and reported the matter to the police.
Officers reviewed footage from the airport’s surveillance cameras and identified Wang as the guilty party and went to see her at her hotel the following morning, the report said.

Wang said that during the flight her cousin’s baby had suffered from diarrhoea and that it was customary in her hometown to toss coins in the hope it would bring the child good luck.

“She said she didn’t realise her action could have had a very serious outcome,” a police officer was quoted as saying, adding that Wang appeared shocked when she realised the trouble she had caused.

However, as her actions had not resulted in any delays to flights or created any other problems, she was charged only with a minor offence.

Wang, who recently completed a bachelor’s degree in medicine and was preparing to sit a graduate school entrance examination, was worried the incident might have an impact on her future education and job prospects, the officer said.

More than 5,000 people commented on the story on news portal 163.com, with one asking: “You are so superstitious, how can you treat patients?”

In recent years there have been numerous reports of Chinese travellers causing delays and being punished for tossing coins onto airport runways and even into aircraft engines.

In April, a woman was detained for throwing six coins as she was about to board a plane in southern China in the hope it would guarantee her a safe trip.

Chinese scientists hail ‘incredible’ stealth breakthrough that may blind military radar systems

  • Researchers at academy of science believe electromagnetic wave model is key that will herald new era in radar detection and avoidance for military ships and aircraft

Chinese scientists have achieved a series of breakthroughs in stealth materials technology that they claim can make fighter jets and other weaponry lighter, cheaper to build and less vulnerable to radar detection.
Professor Luo Xiangang and colleagues at the Institute of Optics and Electronics, Chinese Academy of Sciences in Chengdu, Sichuan province, said they had created the world’s first mathematical model to precisely describe the behaviour of electromagnetic waves when they strike a piece of metal engraved with microscopic patterns, according to a statement posted on the academy’s website on Monday.
With their new model and breakthroughs in materials fabrication, they developed a membrane, known as a meta surface, which can absorb radar waves in the widest spectrum yet reported.
At present, stealth aircraft mainly rely on special geometry – their body shape – to deflect radar signals, but those designs can affect aerodynamic performance. They also use radar absorbing paint, which has a high density but only works against a limited frequency spectrum.

In one test, the new technology cut the strength of a reflected radar signal – measured in decibels – by between 10 and nearly 30dB in a frequency range from 0.3 to 40 gigahertz.

A stealth technologist from Fudan University in Shanghai, who was not involved in the work, said a fighter jet or warship using the new technology could feasibly fool all military radar systems in operation today.

“This detection range is incredible,” the researcher said. “I have never heard of anyone even coming close to this performance. At present, absorbing technology with an effective range of between 4 and 18 GHz is considered very, very good.”

The lower the signal frequency, the longer a radar’s detection range. But detailed information about a moving target can only be obtained with higher frequency radio waves. Militaries typically use a combination of radars working at different frequencies to establish lines of defence.

The Medium Extended Air Defence System, Nato’s early warning radar, operates at a frequency range of 0.3 to 1 GHz. The American Terminal High Altitude Area Defence system, the missile defence radar that caught Beijing’s attention when it was deployed in South Korea in 2017, operates at frequencies around 10 GHz.

Some airports use extremely short-range, high-frequency radars running at 20 GHz or above to monitor vehicle and plane movements on the ground, but even they might not be able to see a jet with the new stealth technology until it is overhead.

“Materials with meta surface technology are already found on military hardware in China, although what they are and where they are used remains largely classified,” the Fudan researcher said.

Luo and his colleagues could not be reached for comment. But according to the academy’s statement and a paper the team published in the journal Advanced Science earlier this year, the stealth breakthroughs were based upon a discovery they made several years ago.

They found that the propagation pattern of radio waves – how they travelled – in extremely narrow metallic spaces was similar to a catenary curve, a shape similar to that assumed by chains suspended by two fixed points under their own weight.

Inspired by catenary electromagnetics, the team developed a mathematical model and designed meta surfaces suitable for nearly all kinds of wave manipulation.
These included energy-absorbing materials for stealth vehicles and antennas that can be used on satellites or military aircraft.
Zhu Shining, a professor of physics specialising in meta materials at Nanjing University, said the catenary model was a “novel idea”.
“The Institute of Optics and Electronics in Chengdu has conducted long-term research in this area which paved a solid foundation for their discoveries. They have done a good job,” Zhu said.
“Scientists are exploring new features of metal materials, some of them are already in real-life applications.”

An 84-year-old woman with Alzheimer’s disease in southwestern China stunned her neighbours by climbing out of a lavatory window in a high-rise building and down from her 14th-floor flat.
The octogenarian was rescued by property management workers, who were waiting near the window of a flat on the fifth floor to intercept her, news website Thepaper.cn reported.
The woman squeezed through the window of her home’s toilet in a residential block in Chengdu, Sichuan province, on Thursday after she was locked in by relatives, a property management employee said.
“She couldn’t open the door from inside. But she wanted to go out as it was so humid and hot today,” the unnamed worker said.
As she climbed down the outside of the building, her neighbours unfolded a bedsheet on the ground, hoping to catch her if she fell.

Property management workers gave the woman water and food after rescuing her. She was later picked up by her relatives and was reported to have no injuries from her adventure, the report said.

There were 6 million Alzheimer’s disease patients in China in 2015, with around 300,000 new cases reported each year, news portal Sohu.com reported.

A 2016 white paper released by the Zhongmin Social Assistance Institute, a Beijing-based research NGO, said half a million old people got lost in China each year, with a quarter of them diagnosed with Alzheimer’s.

“China is seriously hit by Alzheimer’s disease based on the country’s rapidly ageing population,” Dr Wang Luning, chairman of the Chinese Alzheimer’s Disease Association, told Legal Daily.

“But many people, even some doctors, have little knowledge about this disease, leading to low rates of people seeking diagnosis, the rate of them being diagnosed and being treated all being low.”
