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: China outbreak city Wuhan raises death toll by 50%

The Chinese city of Wuhan, where the coronavirus originated last year, has raised its official Covid-19 death toll by 50%, adding 1,290 fatalities.

Wuhan officials attributed the new figure to updated reporting and deaths outside hospitals. China has insisted there was no cover-up.

It has been accused of downplaying the severity of its virus outbreak.

Wuhan’s 11 million residents spent months in strict lockdown conditions, which have only recently been eased.

The latest official figures bring the death toll in the city in China’s central Hubei province to 3,869, increasing the national total to more than 4,600.

China has confirmed nearly 84,000 coronavirus infections, the seventh-highest globally, according to Johns Hopkins University data.

The virus has had a huge impact on the Chinese economy, which shrank for the first time in decades in the first quarter of the year.

What’s China’s explanation for the rise in deaths?

In a statement released on Friday, officials in Wuhan said the revised figures were the result of new data received from multiple sources, including records kept by funeral homes and prisons.

Deaths linked to the virus outside hospitals, such as people who died at home, had not previously been recorded.

The “statistical verification” followed efforts by authorities to “ensure that information on the city’s Covid-19 epidemic is open, transparent and the data [is] accurate”, the statement said.

It added that health systems were initially overwhelmed and cases were “mistakenly reported” – in some instances counted more than once and in others missed entirely.

A shortage of testing capacity in the early stages meant that many infected patients were not accounted for, it said.

A spokesman for China’s National Health Commission, Mi Feng, said the new death count came from a “comprehensive review” of epidemic data.

In its daily news conference, the foreign ministry said accusations of a cover-up, which have been made most stridently on the world stage by US President Donald Trump, were unsubstantiated. “We’ll never allow any concealment,” a spokesman said.

Why are there concerns over China’s figures?

Friday’s revised figures come amid growing international concern that deaths in China have been under-reported. Questions have also been raised about Beijing’s handling of the epidemic, particularly in its early stages.

In December 2019, Chinese authorities launched an investigation into a mysterious viral pneumonia after cases began circulating in Wuhan.

China reported the cases to the World Health Organization (WHO), the UN’s global health agency, on 31 December.

But WHO experts were only allowed to visit China and investigate the outbreak on 10 February, by which time the country had more than 40,000 cases.

The mayor of Wuhan has previously admitted there was a lack of action between the start of January – when about 100 cases had been confirmed – and 23 January, when city-wide restrictions were enacted.

Around that time, a doctor who tried to warn his colleagues about an outbreak of a Sars-like virus was silenced by the authorities. Dr Li Wenliang later died from Covid-19.

Wuhan’s death toll increase of almost exactly 50% has left some analysts wondering if this is all a bit too neat.

For months questions have been asked about the veracity of China’s official coronavirus statistics.

The inference has been that some Chinese officials may have deliberately under-reported deaths and infections to give the impression that cities and towns were successfully managing the emergency.

If that was the case, Chinese officials were not to know just how bad this crisis would get in other countries, making its own figures now seem implausibly small.

The authorities in Wuhan, where the first cluster of this disease was reported, said there had been no deliberate misrepresentation of data, rather that a stabilisation in the emergency had allowed them time to revisit the reported cases and to add any previously missed.

That the new death toll was released at the same time as a press conference announcing a total collapse in China’s economic growth figures has led some to wonder whether this was a deliberate attempt to bury one or other of these stories.

Then again, it could also be a complete coincidence.


China has been pushing back against US suggestions that the coronavirus came from a laboratory studying infectious diseases in Wuhan, the BBC’s Barbara Plett Usher in Washington DC reports.

US President Donald Trump and some of his officials have been flirting with the outlier theory in the midst of a propaganda war with China over the origin and handling of the pandemic, our correspondent says.

Mr Trump this week halted funding for the World Health Organization (WHO), accusing it of making deadly mistakes and overly trusting China.

“Do you really believe those numbers in this vast country called China, and that they have a certain number of cases and a certain number of deaths; does anybody really believe that?” Mr Trump said at the White House on Wednesday.

French President Emmanuel Macron has also questioned China’s handling of the coronavirus outbreak, saying it was “naive” to suggest the country had dealt better with the crisis, adding things “happened that we don’t know about”.

On Thursday, UK Foreign Secretary Dominic Raab said: “We’ll have to ask the hard questions about how [coronavirus] came about and how it couldn’t have been stopped earlier.”

But China has also been praised for its handling of the crisis and the unprecedented restrictions that it instituted to slow the spread of the virus.

WHO Director General Dr Tedros Adhanom Ghebreyesus has hailed China for the “speed with which [it] detected the outbreak” and its “commitment to transparency”.

Sichuan earthquake survivor ready to join his airborne heroes at China’s 70th anniversary parade

  • Cheng Qiang was just 12 when a magnitude 8 tremor destroyed his village, but he never forgot the heroism of the soldiers sent to help and swore one day to join their ranks
  • Now a squad leader, on October 1 he will also be part of the National Day celebrations in Tiananmen Square

A young man who survived the devastating Sichuan earthquake and vowed to one day join the ranks of the soldiers who spent months rescuing people from the rubble will on Tuesday lead his very own squad of airborne troops in Tiananmen Square as part of the celebrations for the country’s 70th anniversary.
Now 23, Cheng Qiang was just 12 when on May 12, 2008 he and a group of friends played truant from school to go swimming in a local river, Xinhua reported on Thursday.
When the boys had finished their fun they returned to their village in the township of Luoshui to find their school and many other buildings had been razed to the ground. The death toll from the magnitude 8 quake would eventually rise to 87,000, with 370,000 people injured.

In the days and weeks that followed the devastation, tens of thousands of people from around China and the world descended on towns and villages across Sichuan to help with the rescue effort.
But the ones who impressed Cheng the most were the soldiers from the People’s Liberation Army (PLA) with the word “Airborne” printed on the helmets.

“Sometimes they had to remove the debris with their bare hands which were already covered in blood,” he said.

“But they just carried on and eventually pulled dozens of people out of the rubble. I knew then that I wanted to be one of them.”

Having the troops in his village made Cheng feel safe, he said, and he spent his days following them around and doing what he could to help.

Three months later, when the soldiers had completed their work and were preparing to pull out, Cheng said he was determined to show his new heroes just how grateful he was to them.

As the villagers gathered at the roadside to bid farewell to the men who had become their saviours, the young boy held up a handwritten sign. It said simply: “I want to be an airborne soldier when I grow up.”

The moment was captured on camera by a press photographer, and the image soon became a symbol of the gratitude felt by the people who had seen their lives and communities shattered but knew they had not been forsaken.

Cheng said he felt dizzy when he first jumped out of a plane. Photo: People.cn

Five years after the troops rolled out, Cheng was preparing to go to college when he heard the PLA was recruiting and that there were places available with the airborne division.

The teenager did not need a second invitation, and after securing a place on a training course and successfully completing it he joined the ranks of his heroes in 2013.

Not that everything was plain sailing, however.

“When I first jumped out of a plane I felt very dizzy and didn’t really know what was going on,” he said.

Thankfully Cheng managed to overcome his vertigo and went on to become a squad leader.

When the preparations were being made for next week’s anniversary celebrations in Beijing, Cheng said he and his squad were chosen to take part.

He said that during the rehearsals for the grand parade, he was repeatedly reprimanded by his trainer for not keeping his knees close enough together, for lifting his feet too high and for letting his gun slip off shoulder.

But he was determined to get it right, and after weeks of hard work and 11 years on from the tragedy that devastated his world, he said he was now ready to put his best foot forward.

“The nightmare of earthquake has long gone,” he said. “I am here to continue the glory of the airborne troops. I am ready for inspection.”
