    They have launched it.

    http://www.ecns.cn/news/2018-12-22/d...k8716152.shtml

    China launched a communications satellite on Saturday, marking the start of construction of a vast space-based communications network capable of covering the entire world with broadband internet service.

    The first satellite in the Hongyun project, which was planned by China Aerospace Science and Industry Corp (CASIC) to be the country's first low-orbit broadband communications satellite constellation, was launched on Saturday at 7:51 am on a Long March 11 carrier rocket at the Jiuquan Satellite Launch Center in northwestern China.

    The spacecraft is tasked with verifying basic designs of Hongyun satellite and demonstrating low-orbit broadband communications technologies.

    Its main payloads are Ka-band transponders and transmission antennae. It also carries several scientific and technical devices to explore Hongyun system's applications in scientific research, environmental survey as well as air and sea transportation, CASIC said in a statement.

    China is often accused of being secretive and not sharing their data. If that is the case, the release by them of a big data sharing platform, will go a long way in changing their image.

    http://www.cctvplus.com/news/2019011...ml#!language=1

    The Chinese Academy of Sciences (CAS) released a big data sharing platform on Tuesday, providing scientists and officials worldwide with information about the earth.

    The platform will provide global users with systematic, diversified and standardized big data through a data, computing and service integrated information sharing system.

    Up to this point, the platform already has five petabytes of data covering topics such as earth observation, biology, ecology, atmosphere, oceanology and microbiology.

    Guo Huadong, an academic at the CAS, said at the press conference on Tuesday that the platform has combined data collected from multiple decades.

    "The biggest feature of the platform is its multidisciplinary integration, which covers a large amount of data accumulated by dozens of institutes from the CAS on the environment, biology, ecology and so on. It has integrated the data of the past few decades," said Guo.

    "China is beating the United States in the new space race"

    https://spacenews.com/op-ed-china-is...ew-space-race/

    The Chinese are beginning to bear the fruits of 30 years of massive, state investment into developing their STEM education (as well as a having a coordinated strategy for ensuring their young people were successful in entering those fields). For years, China has identified science, technology, engineering, and math as the source code to creating a truly dominant state. Having been raised on what the now-deceased former prime minister of Singapore, Lee Kuan Yew, once referred to as the “wolf’s milk of nationalism,” the ruling Chinese Communist Party have nursed a grudge against the West for what they refer to as the “century of humiliation.”

    Historically, a great power — possibly the greatest world power before the rise of Europe in the 14th century — China was laid low by internal strife and outward pressures exerted on them by European and Japanese colonialism in their country, as well as American meddling in their affairs in the 19th and 20th centuries. Whereas most Americans have forgotten the impact of the “Open Door” policy in China, Beijing has never allowed their people to forget it. This ancient country (run by a totalitarian quasi-communist government) has invented a self-serving narrative of national victimhood coupled with the promise of national greatness. It is a compelling narrative to many Chinese.

    A brief history of the cotton seeds carried to the moon by China's Chang'e-4 probe.

    http://www.xinhuanet.com/english/201..._137796785.htm

    An experiment that saw the first-ever plant sprouting on the moon last month was born in a natural disaster that devastated China's cotton-industry almost three decades ago.

    Li Fuguang was one of the Chinese agricultural scientists whose years of hard work might one day help lead to a base and long-term human residence on the moon.

    He was on the team that developed the cotton seeds carried to the moon by China's Chang'e-4 probe, leading to the first-ever sprout on the moon.

    The seed is one of the best varieties developed by the Institute of Cotton Research (ICR) of the Chinese Academy of Agricultural Sciences.

    "China's space research finds microgravity promotes iPS cells regenerative potential"

    http://www.xinhuanet.com/english/201..._137885881.htm

    Research findings from China's Tianzhou-1 Space Mission have shown that the microgravity environment in space promotes heart cell differentiation of mice induced pluripotent stem (iPS) cells, providing new perspectives on future human space travel.

    During space travel, the human body is in a state of weightlessness due to minimal gravitational pull from the earth, which is known as microgravity. Exposure to microgravity may have a profound influence on the physiological function of human cells.

    Researchers from China's Academy of Military Medical Sciences, Tsinghua University and the Shanghai Institute of Technical Physics, Chinese Academy of Sciences took the opportunity of the Tianzhou-1 space mission, China's first cargo spacecraft launched in 2017, to investigate how spaceflight may affect cardiac differentiation of mice iPS cells.

    China is poised to overtake the US in AI.

    http://www.spacedaily.com/reports/Ch...chers_999.html

    China is poised to overtake the United States in artificial intelligence with a surge in academic research on the key technology, an analysis published Wednesday showed.

    The analysis by the Allen Institute for Artificial Intelligence showed China has already surpassed the US in published papers on AI -- although many of these were considered "medium-quality" or "low-quality."

    But the researchers said China is likely to top the US in the most-cited 50 percent of papers this year, the most-cited 10 percent of papers next year, and in the top one percent by 2025.

    China has tested a new type os solar cell in near space.

    http://www.ecns.cn/news/2019-03-15/d...u2192066.shtml

    Chinese researchers have found that perovskite solar cells can retain most of their power conversion efficiency in near space, providing perspectives on the new solar cells' future application in space.

    In recent years, perovskite solar cells (PSCs) are of huge interest to the academic community and the photovoltaics industry due to their potential of achieving higher efficiency and low production costs compared to traditional silicon solar cells.

    According to researchers from China's Peking University, Academy of Opto-electronics, Chinese Academy of Sciences and Northwestern Polytechnical University, PSCs have great potential for developing the new-generation energy technology for space application, but little research has been done to test the stability of PSCs in the extreme space environment.

    "China’s space program soars"

    https://www.asiatimes.com/2019/03/op...program-soars/

    The first true rocket was fired by China in 1232, and when the United States landed a man on the moon exactly 50 years ago, China was mired in political turmoil. The country didn’t send an astronaut into space until 2003. But now it’s catching up. China is quickly becoming one of the most ambitious and pioneering nations when it comes to exploring space. The Chinese space program is one the fastest-growing in the world today.

    From its relatively humble beginnings 60 years ago, the Chinese program has come to be one of the biggest contenders in the modern-day space race. Between its inception in the late 1950s and the turn of the century, the program experienced a gradual buildup in terms of technology, infrastructure and capability. In time, this would set the stage for China becoming an official major power in space. By 2003, the first crewed mission to Earth orbit was successfully launched. That same year, the China National Space Agency (CNSA) inaugurated the Chinese Lunar Exploration Program, which envisaged sending a series of robotic missions to the moon in preparation for an eventual crewed mission.

    "China making great strides in space endeavors, governance"

    http://www.globaltimes.cn/content/1146045.shtml

    China is playing an increasingly important role in mankind's quest to explore the universe, even though the country still lags behind many of its international peers in a number of areas, Chinese space experts and commentators said on Monday.

    The comments came after worldwide audiences witnessed the first "event horizon" of M87, a black hole at the center of the Virgo A Galaxy, in simultaneous press conferences in global cities last week. Sixteen Chinese scientists participated in the creation of the photo, working in areas such as computer modeling and data analysis. But some argue that China's role can be bigger.

    Space experts and commentators said China's capacity in exploring the cosmos still lags behind developed countries such as the US, Japan and members of the EU.

    Cosmological exploration is a multifaceted effort, ranging from observing the universe from the Earth or its orbits to sending spacecraft to the stars. Theoretical study and analysis are equally important.

    "China develops unique heat-resistant material for hypersonic aircraft"

    http://www.globaltimes.cn/content/1147843.shtml

    Chinese scientists have developed a new heat-resistant material for hypersonic aircraft which can endure over 3,000 C from friction caused by a Mach 5-20 flight within the atmosphere.

    The lead scientist on the project said the material outperforms all similar foreign-made ones with its high melting point, low density and high malleability.

    The new material enables a hypersonic aircraft to fly at Mach 5-20 within the atmosphere for several hours, as the high heat resulting from the friction between the aircraft and the air reaches between 2,000 C to 3,000 C, a temperature normal metal would not be able to endure.

    Normal metals melt at around 1,500 C, but this new material can bear over 3,000 C for an extended period, state-owned Hunan Television reported recently.
