    As for me China will become a global leader in research. just look at the leap this country has done in all areas of science. Of course China has a lot of flaws and this country has made a lot of mistakes but still we should not underate it.

    China is using space to create high yielding crops. They started doing this on Aug 5, 1987, when China launched its first seed samples into space. Since then hundreds of varieties of space crops have been planted nationwide.

    http://www.chinadaily.com.cn/a/20201...ba93d27_1.html

    Now, modern technologies have produced quality seeds from an equally fantastic source-outer space.

    These seeds have produced a range of crops, from tomato vines that can sprawl across 150 square meters of land and bear 10,000 fruits, to giant black-eyed pea sprouts measuring nearly a meter long, according to the China Aerospace Science and Technology Corp, or CASTC.

    This progress has been achieved through space-induced mutation breeding, also known as space mutagenesis.

    "Space contractor eyes 5G technology at sea"

    http://www.chinadaily.com.cn/a/20201...d0ba99770.html

    China Aerospace Science and Industry Corp, a major space contractor, is striving to use its satellite technology to enable 5G telecommunication service at sea.

    The State-owned space conglomerate conducted China's first technology demonstration tests using a low-orbiting satellite to enable 5G communication and internet-of-things services on waters off Daishan county in Zhejiang province last month.

    Engineers and crew aboard a local maritime safety bureau's patrol ship, which was sailing in waters off Daishan during the tests, made 5G-based phone calls and held video conferences with their colleagues on land, and they also used internet to check their social-networking accounts.

    The signals were transmitted through a gateway station mounted on the vessel and a low-orbit, experimental broadband communications satellite developed by CASIC.

    "China Just Turned On Its Artificial Sun"

    https://www.popularmechanics.com/sci...usion-reactor/

    China has switched on its record-setting “artificial sun” tokamak, state media reported today. This begins a timeline China hopes will be similar to the one planned by the global International Thermonuclear Experimental Reactor (ITER) project.

    The HL-2M tokamak has been iterated since 2006, but today's switch-on represents the Experimental Advanced Superconducting Tokamak (EAST) team’s road to true fusion ignition after years of planning and work.

    In 2018, EAST made news when the tokamak reached 180 million degrees. In 2019, EAST pushed the boat out further and announced plans to double that temperature in 2020—reaching the tokamak's prime operating temperature of 360 million degrees. This hasn't happened yet, but there’s still time in 2020, and COVID-19 has affected all the world’s scientific progress this year. If the EAST team is a few months late, we’ll still count that as a win.

    "Rice seeds carried to the moon and back sprout"

    http://www.chinadaily.com.cn/a/20201...d0ba9f5cd.html

    Some of the 40 grams of rice seeds that made a round trip to the moon have sprouted and are ready for follow-up studies, according to Science Daily on Monday.

    The rice seeds traveled to the moon and returned to Earth after 23 days of flight aboard China's Chang'e 5 lunar probe. This marks the first time China conducted a deep space induced mutation breeding experiment on rice.

    The seeds were handed over to their provider, the National Engineering Research Center of Plant Space Breeding of South China Agricultural University, on Dec 23.

    China was the first country to use space technology to induce mutation breeding of crops. "Mutations are the basis of species evolution, as well as the basis of breeding of new variety," said Guo Tao, deputy director of the space breeding center.

    "China develops new tentacle-like robot to clear space debris"

    http://www.xinhuanet.com/english/202..._139721412.htm

    Removing trash in space will now be easier thanks to a China-developed continuum robotic arm.

    Inspired by human limbs, most robots are created with discrete links rigidly connected by joints. The continuum robot, in contrast, can move by bending through a series of continuous arcs producing motion akin to tentacles or snakes.

    Researchers from Tianjin University have developed such a robotic arm that can be used to chase down and collect debris from satellites and other space technology orbiting high above Earth.

    The robotic arm, which resembles the arm of an octopus or the trunk of an elephant, includes a central backbone made up of a superelastic metal alloy of nickel and titanium, which can revert naturally back to its original shape after being bent or deformed by outside forces. It also has a camera and a grasping claw attached to the head.

    China could not have made the progress in science, without the dedicated staff working in it. Here is the story of one of them.

    https://www.shine.cn/news/in-focus/2103075571/

    Zhang Yuhua has been party to China’s major aerospace milestones for the last three decades, from the first manned space flight to probes to the moon and Mars.

    She now serves as the deputy chief commander of the Chang’e-5 and Tianwan-1 space missions.

    Chang'e-5 has brought back the world’s first lunar samples in 44 years, while the Mars probe Tianwen-1 is now orbiting the red planet and will make a landing in May or June.

    Her career at the Shanghai Academy of Spaceflight Technology, a member of the China Aerospace Science and Technology Corp, spans China’s space program, starting from nothing to visiting a planet over 400 million kilometers from Earth.

    “I used to admire athletes who won competitions and waved their national flags proudly,” Zhang said. “My career has allowed me to help take China’s national flag to the moon and possibly now even farther.”

    She said she has never regretted a career choice made 31 years ago.

    "Seeds cultivated in space from Chang'e-5 grow on earth offering a 'chip for China's grain security'"

    http://www.ecns.cn/news/sci-tech/202...v2681304.shtml

    Around 1,500 rice seeds that travelled with China's Chang'e-5 spacecraft are now growing vigorously on earth. The green seedlings are expected to leave the greenhouse and to be planted in the field at the end of the month, providing a "chip for China's seed security."

    The 40 grams of space rice have travelled with China's Chang'e-5 lunar probe last November. After its 23-day space journey the seeds successfully returned to the earth and were planted at the plant space breeding engineering technology research center of the South China Agricultural University, south China's Guangdong Province.

    This batch of seeds carried in deep space is of significant scientific research value, as it will help to select valuable new genes to serve rice variety breeding, according to experts.

    "It was a breakthrough of mutation rice breeding experiments in deep space," said Chen Zhiqiang, director of the lab center in an interview with Xinhua News Agency.

    "China upgrades ground system for first-generation relay satellites"

    http://www.xinhuanet.com/english/202..._139885202.htm

    China has completed an upgrade of the ground system for its first-generation relay satellite, Tianlian I, according to the Beijing Space Information Transmission Center on Friday.

    The system upgrade marks a major advance for China in the space-based tracking, telemetry and control (TT&C) sector, said the center.

    The four-year upgrade was successfully completed following maintenance downtime for the Tianlian I-02 relay satellite's ground system.

    The upgrade enables the country to operate its two generations of relay satellite systems, Tianlian I and Tianlian II-1, in an integrated manner, said the center.

    It also greatly enhances the reliability of the relay satellite systems, as well as their maintainable and automatic natures.

    The relay satellite systems will further support the country in improving its TT&C capacity, and they will have roles in the country's upcoming space station mission, according to the center.

    "China is developing plans for a 13,000-satellite megaconstellation"

    https://spacenews.com/china-is-devel...constellation/

    China is to oversee the construction and operation of a national satellite internet megaconstellation through coordinating the country’s major space actors.

    Recent comments by senior officials indicate that plans are moving ahead to alter earlier constellation plans by space sector state-owned enterprises and possibly make these part of a larger “Guowang” or “national network” satellite internet project.

    Spectrum allocation filings submitted to the International Telecommunication Union (ITU) by China in September last year revealed plans to construct two similarly named “GW” low Earth orbit constellations totaling 12,992 satellites.
