    Now it has 75 data users worldwide.

    China's carbon dioxide monitoring satellite TanSat has 75 data users worldwide, according to the website of the Chinese Academy of Sciences.

    The 620-kg satellite received 11,000 data orders and 27,478 GB of data downloads.

    TanSat, launched last December, was China's first satellite to monitor greenhouse gas emissions.

    As part of its three-year mission, TanSat thoroughly examines global carbon dioxide (CO2) levels every 16 days, accurate within 4 ppm (parts per million).

    The satellite can observe the sun, moon, solar flares and objects on the ground.

    The satellite has different modes for observing oceans and land, and can constantly adjust its orientation and position. To ensure the accuracy of TanSat, six ground-based observation stations will calibrate and examine observational data.

    China is upgrading its ability to forecast weather. First report is about the weather satellite launched today and the second on the 11more weather satellites it plans to launch by 2025.

    http://www.xinhuanet.com/english/201..._137232615.htm

    China on Tuesday launched the new Fengyun-2H meteorological satellite to improve the accuracy of weather forecasting and provide better meteorological services to countries participating in the Belt and Road Initiative.

    The Fengyun-2H was launched on a Long March-3A rocket at 9:07 p.m., Beijing Time, from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

    It was the 277th mission of the Long March rocket series.

    A geostationary orbit satellite, Fengyun-2H is the last in the Fengyun-2 series. The Fengyun-4 series will dominate China's new generation geostationary orbit meteorological satellites, said Zhao Jian, deputy director of the Department of System Engineering of China National Space Administration (CNSA).
    http://www.xinhuanet.com/english/201..._137232618.htm

    China plans to send 11 more meteorological satellites into orbit by 2025 to further improve its weather forecasting accuracy and ability to cope with natural hazards, according to the China National Space Administration (CNSA).

    The planned satellites include three Fengyun-3 satellites in polar orbit, two Fengyun-4 satellites in geostationary orbit, one dawn-dusk orbit climate satellite, one high-precision greenhouse gas detection satellite and one hyper-spectral satellite.

    China also aims to send a microwave detection satellite into the geostationary orbit to enhance its ability to predict and monitor fast-changing typhoons, rainstorms and other extreme weather. The satellite will work with the Fengyun-4 series to improve forecasting of rainfall and climate.

    A precipitation radar measurement satellite is also planned to improve the accuracy of numerical forecasting of precipitation.

    China set's a new quantum entanglement record.

    http://www.xinhuanet.com/english/201..._137298961.htm

    Chinese scientists have set a world record for entanglement of 18 quantum bits, keeping their lead in the field of quantum computing.

    The research by scientists at the University of Science and Technology of China was recently published in the academic journal, Physical Review Letters.

    The manipulation of multi-particle entanglement is the core of quantum computing technology and has been the focus of international research competition, said Pan Jianwei, an academician of the Chinese Academy of Sciences and a leading scientist of the study.

    Many scientists believe quantum computing could in some ways dwarf the processing power of today's supercomputers. One analogy to explain the concept of quantum computing is that it is like being able to read all the books in a library at the same time, whereas conventional computing is like having to read them one after another.

    Chinese scientist quest to do their own research in space gets full government support.

    http://www.sciencemag.org/news/2018/...s-solar-blasts

    China's ambitious human space missions get most of the headlines, but its fledgling space science program is quietly gaining strength. The Chinese Academy of Sciences (CAS) last week confirmed plans to launch four new scientific satellites beginning in 2020. Coming on the heels of four successful missions, including one devoted to x-ray astronomy and another that demonstrated quantum entanglement over a record-setting 1200 kilometers, these "phase 2" projects will examine areas including solar physics and the hunt for electromagnetic signals associated with gravitational waves.

    Given that China's space science program only started about 10 years ago, the lengthening track record "is impressive, but there are still not many missions given that it's a big country with a big science community," says Xin Wu, a China-born physicist at the University of Geneva in Switzerland who collaborates on China's astrophysics missions. "There is pent-up demand" among Chinese space scientists, he says.

    CAS broke with tradition for one of the new missions, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM). It fast-tracked selection and development to take advantage of a new scientific opportunity, which Xiong Shaolin, an astrophysicist at CAS's Institute of High Energy Physics in Beijing, and his colleagues identified a month after the U.S. Laser Interferometer Gravitational-Wave Observatory announced its historic detection of gravitational waves in February 2016. They proposed putting two satellites into orbit on opposite sides of Earth that together could watch the entire sky for gamma rays emanating from the events that generate gravitational waves. Funding for technical studies arrived a few months later, and the mission has jumped to the front of the launch queue, with a date of 2020. "When you have this kind of opportunity you can't handle it like a normal mission, with selection and review taking 10 or 20 years," Xiong says.

    The US had ARM that was aiming to bring an astroid to orbit the moon and then study it. Some scientist in China are now proposing to capture a small astroid and bring it back to earth!!!

    http://www.xinhuanet.com/english/201..._137342866.htm

    Next time when your kids ask you to bring them a star from the sky, you don't have to shrug and walk away. Tell them to wait, instead.

    A group of Chinese scientists are mulling a bold idea to capture a small near-Earth asteroid, which might be a potential threat, and bring it back to Earth to exploit its resources.

    "Sounds like science-fiction, but I believe it can be realized," said Li Mingtao, a researcher at the National Space Science Center under the Chinese Academy of Sciences.

    Li and his team raised the audacious idea in a contest of innovative future technologies recently held in Shenzhen, south China's Guangdong Province, and entered the finals with another 59 projects.

    The contest encouraged young Chinese scientists to conceive groundbreaking technologies and trigger innovation.

    China's cold atomic clock improves accuracy.

    http://www.xinhuanet.com/english/201..._137348209.htm

    The Chinese Academy of Sciences announced that an atomic clock has lost the equivalent of only one second in 30 million years during its two years in orbit on Tiangong-2, China's space lab.

    Unlike the most atomic clocks, this clock uses cold atom technology to ensure its ultra precision. Hot-atom clocks have almost reached their limits in regard to long-term stability.

    Two articles on how the Chinese government is encouraging their commercial industries. The first is the release of classified information of 4,038 National Defense Patents. The second is setting up an industrial area to produce satellites.

    http://en.chinabeidou.gov.cn/c/1086.html

    In an effort to carry out the in-depth development strategy of military-civilian integration and promote the transformation of national defense technologies into civilian services, the Equipment Development Department of Central Military Commission has for the first time intensively declassified classified information of 4,038 national defense patents to the public through the PLA’s Weapon and Military Equipment Procurement Information Network.

    The reporter learned from the National Defense Intellectual Property Office on April 28 that the intensive declassification of classified information of national defense patents for this time is another beneficial practice for the in-depth development of military-civilian integration after the on-line operation of the National Defense Intellectual Property Information Platform and the intensive declassification of classified information on national defense patents in 2017.
    http://en.chinabeidou.gov.cn/c/1084.html

    The Space Project Development Co., Ltd. of China Aerospace Science & Industry Corp was established in Wuhan on April 26. This company will build up an ecological circle for satellite industry and forge a production force that will produce hundreds of satellites a year through combining advantages of the large-scale satellite manufacturing in the Wuhan National Aerospace Industry Base.

    Another example of China using its advances in space to help other countries.

    http://www.xinhuanet.com/english/201..._137425470.htm

    China's agricultural remote sensing monitoring platform has provided information services to 147 countries and regions, its developer said Tuesday.

    Named CropWatch, the platform was launched in 1998. Based on remote sensing and ground observation data, the system independently assesses crop growth, yield and related information at global and national scales. It is currently one of the major international remote sensing monitoring systems for agriculture.

    The system was initiated by the Aerospace Information Research Institute under the Chinese Academy of Sciences.

    An article in "wired" about all aspects of China's space ambitions including their science fiction stories.

    https://www.wired.co.uk/article/chin...e-mars-landing

    It’s 2050. The Moon has been colonised by China, with its Lunar Palace base growing potatoes, wheat and carrots – though residents also need to get used to eating mealworms for protein. Everything is grown and recycled in the robot-built base’s white, tubular buildings.

    Such are China’s space ambitions. Later this year, with the Chang’e 4 mission (named for a Moon goddess) China will attempt to land a rover on the dark side of the Moon, something that’s never been done before, setting up an experimental lunar base to trial growing potatoes for food, followed by Chang’e 5, which will use robots to build a permanent base ahead of a manned mission. By 2020, it plans to land on Mars. By 2022, its version of the International Space Station will be in place. China is also working on building a space-based solar power array.

    "University of Hong Kong boosts space research in mainland China with HK$10 million for new Hangzhou lab"

    https://www.scmp.com/news/hong-kong/...mainland-china

    The University of Hong Kong is pumping HK$10 million (US$1.28 million) into building a new space research laboratory on the mainland as it seeks a greater role in Chinese projects, including a 50 million yuan (US$7.28 million) microsatellite it is working on with partners there.

    The new facility will be at the University of Hong Kong Zhejiang Institute of Research and Innovation (HKU-ZIRI) near Hangzhou in Zhejiang province.

    “This strategic investment is designed to help put space and planetary sciences and space-related activities squarely on the map at HKU,” said Professor Quentin Parker, associate dean (global) in the faculty of science and acting director of the HKU Laboratory for Space Research.

    Set to open in a few months, the lab will initially have about six members of staff. Next year it plans to launch the microsatellite, named HKU No 1, on a Chinese rocket from one of four mainland sites.

    This article is not about China per say but hints at how technology is being adapted in Asia.

    http://www.xinhuanet.com/english/201..._137523304.htm

    Jack Ma, founder of China's e-commerce giant Alibaba, hailed the prospect of technology and internet in Asia on Wednesday, saying China and companies like Alibaba will take up the responsibility and opportunities to share its technology with the neighbors.

    Despite a late comer to the internet and information technology, governments and entrepreneurs in Asia are showing greater interest in the area, he told audience via video call during South China Morning Post's China Conference held in the Malaysia's capital Kuala Lumpur.

    "Today I think the big advantage of Asia is the confidence of technology and confidence of the internet," he said.

    China to launch the 1st of its 320 Hongyan LEO communications constellation satellite by year end. They hope to complete the constellation by 2025.

    https://gbtimes.com/china-to-launch-...n?cat=business

    China will launch the first of around 320 satellites for a planned low Earth orbit communications constellation before the end of the year, the country's main space contractor has stated.

    The experimental first satellite has been developed under the China Aerospace Science and Technology Corporation (CASC), which revealed last week at the 2018 Zhuhai Airshow that the launch would take place soon.

    The satellite will be sent into a 1,100 km altitude orbit by a Long March 2D launch vehicle to test L- and Ka-band communication capabilities and compatibility in low Earth orbit (LEO).

    How exactly would that work? If a sat is flying over China, content would be censored somehow, then when it's over another part of the world, the whole internet would be accessible? Otherwise, how could they hope to get any international customers?

    It will only go international when they deploy all 320 satellites in 2025.

    From a technical point of view, I expect ground stations are still a necessary part of the system, and they can have whatever controls they want for domestic traffic, while still leaving things more open for international traffic.

    China is making progress with nuclear fusion technology.

    https://gbtimes.com/chinas-artificia...illion-degrees

    A laboratory in eastern China's Anhui Province has announced that its Experimental Advanced Superconducting Tokamak (EAST) has reached a core plasma temperature of over 100,000,000 C - a huge breakthrough in the fusion reactor experiment.

    The ultimate goal of the artificial Chinese sun is to create nuclear fusion similar to that produced by the Sun using deuterium, an isotope commonly found in the sea. This will, in turn, provide a steady stream of clean energy, according to Gong Xianzu, the experiment's director.

    China is investigating if they success in transforming deserts using algae can be used to transform Mars.

    http://www.xinhuanet.com/english/201..._137663679.htm

    Liu has an ambitious goal: letting algae pioneer human migration to Mars.

    He first publicly proposed using algae to transform the environment of Mars about 15 years ago. "The deserts on earth have a similar environment to the Martian environment. We might use our knowledge of desert algae to transform the environment and help construct a human base on the red planet."

    Science fiction writers and scientists put forward the idea of transforming Mars a long time ago, but there was no practical way to realize it. Liu's research made the idea conceivable, said Wang.

    The intense radiation, low air pressure, dramatic temperature changes and bleak environment on Mars are similar to early earth. Algae are primary producers of the earth's biosphere, accounting for 30 percent to 40 percent of the global total, and playing an important role in maintaining biosphere stability, said Wang.
