China's FAST starts search for extraterrestrial intelligence
2020-04-28

The 500-meter-diameter Aperture Spherical Radio Telescope (FAST), China's mega-science project and the world's largest single-dish radio observatory, has embarked on the search for extraterrestrial intelligence (SETI), the Science and Technology Daily reported on Tuesday.

After it became fully operational in January, some analysts believed that FAST would become the major force in searching for and researching into extraterrestrial intelligence, especially with more and more discoveries of exoplanets and revolutionary progress made in instrumentation and observational capabilities.

In a recent study, the team of FAST said the FAST has the potential to detect Earth-like civilizations on thousands of exoplanets, addressing the possibility of the presence of technological civilizations beyond our planet. They said FAST also has the potential to detect whether the neighboring Andromeda galaxy "m31-andromeda" has more advanced technology and civilizations.

Li Di, chief scientist of FAST and research fellow with the National Astronomical Observation of China, told Science and Technology Daily that it is the first SETI search report of FAST, which lays a solid foundation for launching further searches in the future.

The study was reportedly published in The Astrophysical Journal (Apj) and Research in Astronomy and Astrophysics (RAA).

A test version of China's first flexible and inflatable cargo return capsule which was launched into orbit on Tuesday by the Long March-5B's maiden flight, experienced failure during its re-entry to Earth due to an unknown malfunction, the China Manned Space Agency (CMSA) announced on Wednesday.

The cause of the malfunction is now under investigation, CMSA said.

Ji Qiming, an official with the CMSA, said at a Tuesday press conference that the cargo return capsule, which is flexible and inflatable, was the country’s new-generation test vehicle for space cargo shipments, and the mission was to test key re-entry technology of inflatable unfolding style.

According to the Xinhua News Agency, the development of the new cargo return capsule is to achieve a goal of more agile space cargo shipments with reduced cost. The idea of an inflatable capsule was developed by the Second Academy of the China Aerospace Science and Industry Corporation (CASIC) in 2014, in order to increase reliability and significantly lower costs in the payload return process.

China Tests Gigabit LAN on Next-Gen Spacecraft

(Yicai Global) May 8 -- A Chinese manned spacecraft test vessel launched by the country’s workhorse Long March 5B carrier rocket has completed high-speed Local Area Network tests in orbit this week and the speed of this network can reach the level of gigabits, allowing China’s 'taikonauts' to access integrated equipment control on the nation’s space station.

Scientific researchers have built a high-speed local area network on the spacecraft. The network system has completed multi-source data sampling and high-definition image transmission function testing and achieved high-speed data transmission between the systems, Science and Technology Daily reported today. This is China’s first space trial of this technology, per the report.

An intelligent spacecraft information system can be implemented in the space station through this LAN system.

"At that time, astronauts can bring a tablet computer to achieve integrated control of all equipment on the spacecraft, which makes operation easy and greatly reduces the pressure on system design," said Lin Yue, the chief designer of the on-board information network at China Academy of Space Technology.

China's new-generation manned spacecraft test vessel will return to the ground today after a series of tests.

A gigabit is a multiple of the unit bit for digital information or computer storage. Gigabits commonly measure local network and input/output connection data transfer rates.

'Taikonaut' is a portmanteau of the Chinese noun 'taikong' (space) and the Greek suffix 'naut' (navigator).

China Tianyan, world's largest radio telescope, completes data center upgrade
2020-05-08 18:31:13 GMT+8 | cnTechPost

Recently, The 500-meter Aperture Spherical Telescope (FAST), known as the "China Tianyan", received a new development: its data center has been successfully upgraded.

"The upgrade of the data center means that China Tianyan is one step closer to establishing three complete scientific research frameworks for observation, research, and data.


"China Tianyan", world's largest radio telescope, is located in the "Big Pot" deep in the mountains of Kedu Town, Pingtang County, Guizhou Province, in the karst hills that formed millions of years ago.

Its spherical reflective surface is equivalent to 30 football fields and is 138 meters vertical from bottom to top, surpassing the world's largest Huff Pyramid.

As a science and technology infrastructure involving astronomy, mechanics, materials, machinery, radio, IT and other fields, "China Tianyan" is not only the result of more than 20 years of struggle of Chinese scientists but also a breakthrough in the field of science and technology infrastructure in China.

The National Development and Reform Commission recently pointed out the scope of new types of infrastructure, among which innovative infrastructure refers to infrastructure with public welfare attributes that support scientific research, technology development and product development, and major scientific and technological infrastructure such as "China Tianyan" is undoubtedly a typical representative of new infrastructure.

Since its official launch on 11 January 2020, China Tianyan has discovered 132 high-quality pulsar candidates, of which 93 have been identified as newly discovered pulsars.


"FAST is currently the most sensitive radio telescope in the world, more than 2.5 times more sensitive than the American Arecibo telescope and 10 times faster than Arecibo, and is expected to maintain its leading position in the world for at least 20 years," said GENTLE.

China Tianyan generates huge amounts of data over time and as the research mission progresses, the demand for storage capacity and performance is growing. To this end, the National Astronomical Observatory has been promoting the construction of the FAST Research Data Center in recent years.

In the latest upgrade, the National Astronomical Observatory partnered with Inspur Storage to build a 30PB usable capacity, 50GB bandwidth astronomical big data platform with distributed storage AS13000G5 to support "China Tianyan" for astronomical big data storage, processing, and real-time analysis.

This time, the role of wave storage is not only to make "China Tianyan" "can fit" the data, but also to become the "accelerator" of astronomical big data analysis, and play a positive influence in the exploration of the unknown universe field.

In the "China Tianyan" project, Wave Storage ingeniously deployed H nodes for HPC and AI applications and M60 nodes for high-density scenarios in a distributed storage platform to achieve hierarchical storage of hot and cold data, and high-performance nodes to improve the efficiency of astronomical big data processing and analysis; high-density nodes to achieve a single node capacity close to 1PB, providing massive storage space; and free data flow between different levels of storage according to astronomical business needs, bringing more rapid research experience.

"China Tianyan" data center expert said, "We are very impressed by this cooperation with Wave Storage, which not only has hardcore products, but also professional production and delivery team. Even in exceptional circumstances such as the epidemic, Wave Storage was able to move the project forward to go live earlier than we had expected."

In the future, with the accelerated completion of the "China Tianyan" three complete scientific research frameworks of observation, research, and data, China's astronomical research strength is bound to rise to another level and showcase China's scientific research strength in the vast universe.

Chinese scientists lead the detection of soft X-ray polarization from the Crab Nebula
Source: Xinhua| 2020-05-12 20:46:50|Editor: huaxia

BEIJING, May 12 (Xinhua) -- Chinese scientists and their international collaborators have detected soft X-ray polarization from the Crab Nebula with their space program PolarLight, reopening the window of soft X-ray polarimetry in astronomy after more than four decades.

The research led by Tsinghua University was published in the journal Nature Astronomy.

Researchers also discovered a variation of X-ray polarization right after a glitch of the Crab pulsar, suggesting that the pulsar magnetosphere may have altered after the glitch.

The PolarLight project used a soft X-ray polarimeter onboard a CubeSat, which was manufactured by a Chinese commercial space company and launched into space in 2018.

The detector developed by the research team has a small surface area, similar to the size of a matchbox. It has a designed life of five to 10 years, allowing the team to conduct long-term astronomical observations.

Feng Hua, the leading researcher, said astronomy is a field of science driven by observations. New observational techniques, also called new windows, are of essential importance.

The technique that is used in the PolarLight project will be utilized in the enhanced X-ray Timing and Polarimetry mission (eXTP), a China-led project to be launched in 2027 to explore mysterious celestial bodies, such as black holes and neutron stars, Feng said, adding that more fruitful scientific results are expected in this area.

China recently completed an in-flight verification for satellite drag-free control technology, marking a step forward in the country's space-based gravitational wave detection program.

State-owned China Aerospace Science and Technology Corporation (CASC) confirmed the successful verification with the Tianqin-1, the country's first satellite for space-based gravitational wave detection, on Saturday, Beijing-based newspaper Science and Technology Daily reported on Sunday.

Drag-free control technology blocks external forces that affect a satellite, excluding gravity, so it can remain static and stable, the report said, noting that forces need to be canceled including sunlight pressure and atmospheric drag.

Based on flight data, the new technology reduced external force on Tianqin-1's acceleration by less than 1-400 millionth of the gravitational acceleration, marking a better result than the European Space Agency's GOCE satellite's 1-300 millionth.

The results indicate that external forces have an acceleration effect of less than a human yawn, the report said.

The Chinese technology was successful in reducing displacement from external forces to 30 nanometers, or 1-4,000th of the diameter of an adult human hair strand. It is also better than the internationally well-known LISA satellite's 40 nanometers, according to Science and Technology Daily.

The two results have significant theoretical and practical value in detecting Earth's gravitational field, extraterrestrial objects, and gravitational waves, according to the report.

With this latest achievement, the Tianqin-1 has proven the level of its advanced technology.

The research institute under CASC started conducting related research in 2010, according to Science and Technology Daily, which also noted that China still need time to practically apply the technology in gravitational wave detection.

Launched on December 20, 2019, the Tianqin-1 is China's first technology demonstration satellite in the Tianqin gravitational wave detection program.

Initiated by Sun Yat-sen University in South China's Guangdong Province in 2015, the program will eventually consist of three satellites that will form an equilateral triangle around Earth, the Xinhua News Agency reported.

China tests Mars probe for 2020 Mars mission

March 10, 2020

BEIJING, March 10 (Xinhua) -- The Beijing Aerospace Control Center announced on Tuesday that China completed a probe test ahead of an exploration mission to Mars this year.

The wireless network test is the only joint ground rehearsal between the mission center and the spacecraft.

According to the center, the test has not been affected by the novel coronavirus epidemic, and the technical staff is working hard to ensure the success of the mission.

As scheduled, China's first Mars exploration mission will take place in 2020. Cui Xiaofeng, head of the mission team, said the spaceflight control would be difficult and full of challenges as the Mars probe would take nearly seven months to land on the planet.

Several countries have revealed plans for launching Mars probe missions this year.

http://en.people.cn/n3/2020/0310/c90000-9666767.html ​

Commentary

China will do in one shot, what the Soviet/Rus' could never achieve in two decades of fruitless attempts and dozens of space probes spoiled (and even 100% Soviet failure in 6 landing attempts, with only 14 seconds functional probe once on the surface), thus having wasted in the process billions of rubles much needed for its social and economic development, and ending consequently with a catastrophic surrender at the end of the cold war: a successful mars landing at the first attempt!

And this, by next year! A feat that not even the U.S. could realize at the first launch. (The first U.S. landing on Mars was attempted by Viking-1 only after four Mariner probes flybys and two more Mariner orbiters. This means after 6 missions, and 11 years -from 1964 to 1975-. The first U.S. rover, Sojourner would only be launched after 2 more missions and 21 years later, in 1996.)

After this first step, China will start the development of Mars, based on the first come first served basis. First a small outpost, then large scale robotic mining for its mineral resources, including the most strategic rare earth. With these rare earth minerals, the electronic industry will be able to populate the entire red planet with AI industrial robots, and also military ones. Therefore ensuring the armed defence of this vital asset, in deterring the eternal greedy 8 Allied Powers' imperialists (U.S./E.U. and Vrus') from stealing it from the Chinese people. Lastly, new spaceships will be designed in Martian research institutes and produced in Martian factories by the Chinese robots scientist and robot engineers, allowing the further conquest of the Moon, Venus and Mercury, and as far as the satellites of Jupiter, Saturn, Uranus and Neptune.

By 2049, the P.R.C. will celebrate its founding's centennial, after having finally implemented the policy of Socialism with Chinese characteristic over the entire Solar system, and totaling some 100 billions citizens -humans on Earth, robotic and synthetic-organic on all the other planets-!



Dude, the same Indo-Euro butthurt sour grapes already said this back in January when China was the first nation in the world at the forefront of the fight against the most deadly Coronavrus' or COVID-19, the acronym used in the U.S. military for Covert Operation with Virus Inducing Death # 2019.

And see today...China is the first in the world to have emerged victorious, while both the Paleo Romans centered around ‎Pasargadae‎, the Mediterranean Romans settled around Mediolanum and the New Romans settled around Washingtonium are totally overwhelmed by the scope of the scientific, medical, logistic, economic and industrial challenges posed by this pandemic, letting the numbers of their infected and deaths soaring like space rockets totally out of control!

Meanwhile, this latest hard won victory has already demonstrated that China, under the most wise leadership of the CPC of Comrade President Xi Jinping is the sole superpower on earth qualified to take the lead for humankind in every fields of developments, including the space conquest that will see the Chinese civilization span from Mercury to the Oort Cloud before 3 decades! Deal with it!

Alas this was too good to be true.

Eternal enemies of China unable to launch their own Mars probe this year, having totally collapsed under the COVID-19 outbreak, will have to postpone their EXOMARS mission to 2022!

And suddenly, coming out of the blue, the chief scientist of China's Mars exploration program, Academician Ten Thousands Satellites (万卫星: Wan Weixing), died yesterday aged 62, just two months before the launch of China's Tianwen-1 Mars orbiter and rover mission.

Two in a week, after the Chinese Ambassador to Israel, His Excellency Mr Du Wei, that has been found dead in his apartment north of Tel Aviv on 17th May 2020!

Coincidence? I think not! Norsemen squatters busy plotting against the rise of the Pax Sinica lately.
