China successfully launched a prototype of its next-generation manned spacecraft – without astronauts – along with a new version of its heavy-lift Long March 5 rocket on Tuesday, its space agency said.
The Long March 5B rocket was launched into low-Earth orbit from the Wenchang Satellite Launch Centre on Hainan Island in the country’s south.
The launch marks a significant step forward for China’s two big space exploration ambitions – building a space station and a mission to Mars.
A modified version of China’s most powerful rocket, the Long March 5B is 53.7 metres (176 feet) tall. It will carry the next-generation crew capsule prototype designed to replace the Shenzhou spacecraft, to transport astronauts to its planned space station in low-Earth orbit.
China aims to launch the core module of that space station designed for three crew members, the Tianhe, in 2021. Beijing has been planning to build its own space station for decades as an alternative to the International Space Station, from which China has been excluded by the United States over security concerns.

The prototype capsule has a different configuration to Shenzhou’s and it will be able to launch and land with three astronauts on board as well as up to 500kg of cargo, according to state news agency Xinhua. That will mean it can be used to transport research specimens and hardware from the space station back to Earth.
While the Shenzhou can ferry three astronauts, the new capsule design will be able to accommodate up to six crew members and, unlike the Shenzhou, it will be capable of carrying them to the moon, according to Chinese media reports.
Its systems, performance in orbit and parachute deployment are among the areas that will be put to the test during the launch.
Why China’s next Long March 5 rocket mission will be about restoring national pride
14 Dec 2019
The long-anticipated space station project has been delayed by problems in the development of heavy-lift rockets to carry the modules. In 2017, an oxygen supply problem caused the failure of the second Long March 5 launch, and it
plunged into the Pacific Ocean shortly after take-off. But in December it successfully
carried a Shijian-20 satellite into orbit, while the liquid oxygen-liquid hydrogen engines used in both the Long March 5 and 5B rockets passed testing in January.
China’s other space ambitions include a Mars probe, and landing astronauts on the moon within the next decade. For the Mars mission, the unmanned orbiter and rover Tianwen-1 will be launched by the Long March 5 and it is expected to take up to seven months for the probe to reach the red planet. China would be the third country to do so – after the United States and the Soviet Union.
Zhang Kejian, head of the China National Space Administration, said China was on track to launch the mission this year, with July the likely launch date.

BEIJING, May 1 (Xinhua) — China is getting the world’s largest workforce back to work as the nationwide battle against COVID-19 has secured major strategic achievements.
The unprecedented fight has nurtured new trends in the workplace. For example, more attention is being paid to public health and e-commerce to boost consumption and emerging sectors brought by new applications based on the country’s rapid new infrastructure development of 5G networks and data centers.

ANGELS OF PUBLIC HEALTH
Ye Man, head nurse of gastrointestinal department of Hubei General Hospital East District, one of the five remaining COVID-19 designated hospitals in Wuhan, is taking her first weeklong vacation since January.
The 34-year-old mother of two started to take a week off on Monday, one day after her hospital cleared all remaining confirmed COVID-19 patients. The nine ICU wards in her hospital had been kept occupied over the past several months.
Friday marked International Workers’ Day, and the start of China’s five-day public holiday. Ye said she planned to visit urban parks with her family during the holiday.
At her busiest point, she and her colleagues took care of a ward filled with 40 COVID-19 patients.
“It was a really tough time,” she recalled. She had to wear a protective gown and a mask for nine hours a day and be separated from her family to avoid possible cross-infections.
Wuhan, capital of central China’s Hubei Province and once hard hit by COVID-19, cleared all confirmed cases in hospitals on April 26. Over 42,000 medical workers mobilized nationwide to aid Hubei have contributed to achieving a decisive outcome in the fight to defend Hubei and Wuhan.
In an inspection tour to Wuhan on March 10, President Xi Jinping, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission, lauded medical workers as “the most beautiful angels” and “messengers of light and hope.”
To reward brave and dedicated medics, major tourist sites in Hubei are offering free entry to medical staff over the following two years.

LIVESTREAMING ANCHORS
“We have a new batch of supplies today. Those who did not get the goods should hurry to buy now,” said Li Xuying, a livestreaming anchorwoman selling agaric mushrooms in Zhashui, a small county deep in the Qinling Mountains in northwest China’s Shaanxi Province.
Li has been prepared for a boom of online shopping in the holiday, because online buyers rushed to her livestreaming website to place orders, after Xi inspected the county and chatted with her in the village of Jinmi during a recent tour to Shaanxi.
“I used to sell goods worth about 50,000 yuan (7,070 U.S. dollars) on average after a six-hour livestreaming session. Now the sales are 10 times that,” she said.
Li was one of the 10 sales staff sent by the local agricultural e-commerce firm to Chinese e-commerce platform Taobao’s headquarters for livestreaming training. She said livestreaming is effective in bridging buyers and farmers, through which viewers can watch planting and harvesting online.
With the number of netizens in China reaching 904 million in March, e-commerce has been one of the popular means of promoting the sale of farm produce and helping farmers shake off poverty. Despite the impact of COVID-19, the country is determined to eradicate absolute poverty by the end of this year.

HI-TECH WORKERS IN “NEW INFRASTRUCTURE” BUILDING
As an elasticity calculation engineer of Alibaba Cloud, Zhao Kun and his colleagues always stay on alert for high data flow, for example, brought by the anticipated online shopping spike during the holiday.
“The profession, which may sound obscure, is actually closely connected to everyone’s life, as cloud computing is the infrastructure supporting high-tech applications of artificial intelligence and blockchain,” said Zhao.
The Chinese leadership has underscored expediting “new infrastructure” development to boost industrial and consumption upgrading and catalyze new growth drivers.
Seizing the opportunities of industrial digitization and digital industrialization, China needs to expedite the construction of “new infrastructure” projects such as 5G networks and data centers, and deploy strategic emerging sectors and industries of the future including the digital economy, life health services and new materials, President Xi has said.
During the epidemic, Zhao and his colleagues expanded more than 100,000 cloud servers to ensure the stable operation of “cloud classrooms” and “cloud offices” for millions of people working and studying from home.
In the “new infrastructure” building, people like Zhao contribute to constructing the virtual infrastructure of an ecosystem, which enables e-commerce, e-payment, online teaching and the digital transformation of manufacturing and supply chain management.
In early April, China released a plan on promoting the transformation of enterprises toward digitalization and intelligence by further expanding the application of cloud and data technologies, to nurture new business models of the digital economy.
