Moon shrinking causes quakes study

(Xinhua)16:53, May 15, 2019

WASHINGTON, May 13 (Xinhua) — The U.S. lunar orbiter observations and lunar seismic data showed that the Moon was shrinking like a raisin as its interior cooled, thus producing quakes along the fault lines on it.

The study was published on Monday in the journal Nature Geoscience.

A team of American researchers designed an algorithm to analyze seismic data recorded by NASAs Apollo missions in 1960s and 1970s which provided epicenter locations of 28 quakes on the Moon from 1969 to 1977. Then they put those data onto imagery of the thrust faults captured by NASAs Lunar Reconnaissance Orbiter (LRO).

The quakes proximity to the thrust faults showed that at least eight of those quakes tend to be resulted from the movement of crustal plates instead of asteroid impacts or rumblings deep within the Moons interior.

The quakes are within 31 km of faults visible in the LRO images, close enough for the team to conclude that the faults likely caused the quakes.

Its quite likely that the faults are still active today. You dont often get to see active tectonics anywhere but Earth, so its very exciting to think these faults may still be producing moonquakes, said Nicholas Schmerr, an assistant professor of geology at the University of Maryland, in a statement.

The researchers also found that six of the eight quakes happened when the Moon was at or near the apogee of its orbit, the farthest point from the Earth.

This is where additional tidal stress from the Earths gravity causes a peak in the total stress on the Moons crust, according to the study.

The Moon wrinkles as its interior cools and shrinks. Its crust is brittle, so the breakage resulted in thrust faults, resembling small stair-shaped cliffs or scarps.

CHONGQING, May 15 (Xinhua) — A remote-controlled car powered by the 5G network completed a test run on Wednesday in Chongqing, a vehicle-manufacturing powerhouse in southwest China.

During the test run, a remote operator was able to control the car while watching the live feed of road conditions supported by the 5G network.

The car was co-developed by the Chongqing subsidiary of China Telecom, China Automotive Engineering Research Institute Co. Ltd., and Datang Mobile Communications Equipment Co. Ltd.

Tu Lefei, an expert with the Chongqing subsidiary of China Telecom, said the researchers were working to incorporate more functions such as hazard warnings into the car.

Test data showed that the 5G network is able to provide a peak single-user download speed of 1.6 Gbps, nearly 16 times faster than that of 4G services.

BEIJING, May 15 (Xinhua) — China will construct a new National Supercomputer Center in Zhengzhou, central Chinas Henan Province, according to Science and Technology Daily on Wednesday.

It will be Chinas seventh national supercomputer center. The others are in the cities of Tianjin, Jinan, Changsha, Shenzhen, Guangzhou and Wuxi.

The construction of the new supercomputing center is scheduled to be finished in 2020. It will be capable of performing 100 petaflops per second.

Constructed and operated by Zhengzhou University, the new supercomputing center will develop applications in artificial intelligence, equipment manufacturing, precision medicine and biological breeding, said the newspaper.

Chinas satellite navigation industry sees rapid development

(Xinhua)09:33, May 16, 2019

BEIJING, May 15 (Xinhua) — Chinas satellite navigation and location services industry achieved a total output value of 301.6 billion yuan (about 43.93 billion U.S. dollars) in 2018, up 18.3 percent from the previous year, according to an annual industry report.

The data was published in the White Paper on the Development of Chinas Satellite Navigation and Location Services Industry (2019), which was released by the GNSS (global navigation satellite system) and LBS (location-based service) Association of China on Wednesday.

The industrys core sectors, which are directly related to the development and application of the satellite navigation technology, include chip, device, algorithm, software, navigation data, terminal equipment and infrastructure. These sectors reported 106.9 billion yuan in output value, accounting for 35.44 percent of the industrys total.

The BeiDou Navigation Satellite System (BDS) contributed 80 percent to the output value generated by the core sectors. The system raked in a total of 194.7 billion yuan with related products and services.

China has launched 44 BDS satellites, and the system has been applied in many industries including transport, maritime affairs, electricity, civil affairs, meteorology, fishery, surveying and mapping, mining and public security.

According to the report, over 80 million sets of domestic BDS terminal products had come into service by the end of 2018. The total number of terminal products, including smartphones, installed with BDS compatible chips was close to 700 million.

There are 14,000 enterprises and institutions in the field of satellite navigation and location services in China, with more than 500,000 employees. By the end of 2018, 51 companies in the industry had been listed, said Li Donghang, deputy secretary-general of the GNSS and LBS Association of China (GLAC).

By the end of 2018, the total number of satellite navigation patent applications in China exceeded 60,000, ranking first in the world, the report said.

The satellite navigation and positioning products from Chinese enterprises have entered markets in more than 100 countries, among which BDS has been applied in more than 30 countries and regions along the Belt and Road, Li said.

To enable BDS to better serve the economic and social development in Belt and Road countries and regions, China has established BDS cooperation mechanisms with countries and organizations in South Asia, Central Asia, ASEAN, the Arab League and Africa, strengthening technical exchanges and personnel training, and building BDS overseas centers.

The worlds first unmanned electric port tractor based on BDS, laser radar, millimeter wave radar and cameras was put into trial operation in the Tianjin Port in 2018. It can drive and park precisely, load and unload containers and avoid obstacles without an operator, Li said.

Chinas main domestic aviation enterprises have made plans to introduce a BDS-based management system to monitor planes in real time.

Since 2018, BDS has become one of the three major satellite systems serving the global ocean observation network.

By the end of 2018, BDS had been used in more than 30,000 agricultural machines in over 1,200 farms across China, covering more than 4 million hectares of cultivated land.

With quick and sensitive detection technology, the BDS-based gas leakage detection vehicle can locate a gas leakage point within a 150-meter radius, which is 10 times more efficient than the traditional method, Li said.

So far, BDS has been used to help detect gas leakage in more than 600 cities and towns across China, covering gas pipelines with a total length of 800,000 km.

With the development of 5G technology, BDS combined with 5G is expected to be used widely in fields such as airport scheduling, robot patrol, unmanned aerial vehicles, building and vehicle monitoring and logistics management, Li added.

Private space firms rapidly growing in China report

China had 141 registered commercial space companies in 2018, 90 percent of which are private, according to a report, and experts said that private commercial space companies have experienced stable development in recent years but lack more talent.

Of the 141 Chinese commercial space companies, 36 are satellite manufacturers, 22 satellite launching companies, 39 satellite operators and 44 satellite application companies. They cover the industrial chain space, according to a report Futureaerospace, a Chinese industry think tank, released on its WeChat account on Tuesday.

Zeng Zhiyuan, a senior analyst at Futureaerospace, told the Global Times on Wednesday that commercial space companies include private and state-owned ones.

State-owned commercial space companies have been established for more than 10 years. The number of private space companies in China surged in recent years, with 57 established within three years, the report said.

This shows Chinas policies to encourage private space development are beginning to bear fruit. State-owned commercial space companies have all kinds of products and services in the industrial chain, and private companies are growing fast to supplement them, Zeng said.

Huang Zhicheng, an expert on space technology, told the Global Times on Wednesday that Chinas private commercial space companies are developing well, but are still at an early stage compared to Chinas state-owned companies and private companies in the US.

State-owned companies still contribute far more to the commercial space market because the private ones were only recently established and do not have enough talent yet, Huang said.

By 2025, China is expected to have about 3,100 commercial satellites, and the market could be worth 13.6 billion yuan ($1.98 billion).

Among the 39 satellite launches in 2018, 13 were related to commercial activities, which sent 36 satellites into space, according to the Futureaerospaces report.

Interview Chinas development has positive impact on Asia-Pacific UN official

(Xinhua)13:45, May 24, 2019

BANGKOK, May 24 (Xinhua) — Chinas significant progress in economy and other areas has a positive impact on the Asia-Pacific region and the world as China and many other countries in the region are parts of the global value chains, said a UN official.

One of Chinas major achievements is its significant reduction of the poverty rate, having helped hundreds of millions of people escape poverty, Armida Alisjahbana, executive secretary of the UN Economic and Social Commission for Asia and the Pacific (ESCAP), said in an interview with Xinhua in Bangkok.

As China puts emphasis on sustainable economic development, Chinese development could be even more beneficial to the regional countries.

The latest fruits of Chinas development such as bike-sharing, e-payment and renewable energy can also benefit other countries through cooperation, she added.

In April, Alisjahbana attended the second Belt and Road Forum for International Cooperation in Beijing, during which she and Chinese State Councilor and Foreign Minister Wang Yi signed a memorandum of understanding (MoU) between Chinas Foreign Ministry and ESCAP.

The MoU deepened the cooperation formed since the two sides signed a letter of intent to boost the Belt and Road construction in 2016, which is the first cooperation document on the Belt and Road Initiative (BRI) signed by the Chinese side and an international organization, she said.

The executive secretary added that she was impressed by Chinese President Xi Jinpings keynote speech at the forum last month, in which sustainable development came up several times.

She said she believes the BRI projects would be sustainable and contribute to the realization of the UNs Sustainable Development Goals.

The UN official, appointed to the position last year after working in the Indonesian government, the World Bank, and the Asian Development Bank, also expressed concern about the U.S.-China trade tensions.

Many countries have trade relationships with China as well as with the United States. If because of the trade tensions, trade activities (and) trade volumes among countries decrease, then it will impact negatively, she said.

In the name of protecting domestic industries, the United States has placed steep tariffs on billions of U.S. dollars worth of products from its major partners, including Canada, China, Japan and the European Union, raising trade tensions around the world and shaking the foundation of the global trading system.

In the latest flare-up with China, Washington increased additional tariffs on 200 billion U.S. dollars worth of Chinese imports from 10 percent to 25 percent earlier this month, and has threatened to raise tariffs on more Chinese imports.

In response, China has announced that it will raise additional tariffs on a range of U.S. imports from June 1, and will fight to the end.

Beijing has also repeatedly called on the United States, which started the row, to get back on the right track as soon as possible and meet China halfway to achieve a mutually beneficial and win-win agreement on the basis of mutual respect.

Alisjahbana said she hopes the worlds largest two economies will end their trade disputes with a win-win solution soon.

I hope this trade (tension) can be resolved, will be resolved soon in a mutually beneficial manner, because directly and indirectly, this trade tension will have impact on the rest of the world and certainly the region, she said.

SpaceX rocket brings first batch of 60 internet satellites into space

(Xinhua)14:10, May 24, 2019

WASHINGTON, May 23 (Xinhua) — U.S. private space company SpaceX launched its first batch of 60 Starlink satellites into space on Thursday, in an effort to build a 12,000-strong satellite network capable of providing broadband internet services.

The Falcon 9 rocket, carrying the satellites, was lifted off at 10:30 p.m. Eastern Daylight Time (1430 GMT) from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida.

SpaceX designed Starlink to connect end users with low-latency and high-bandwidth broadband services by providing continual coverage around the world using a network of thousands of satellites in low Earth orbit, according to the company.

Approximately one hour and two minutes after the liftoff, the Starlink satellites began deployment at an altitude of 440 km, according to the SpaceX live broadcast.

The satellites will then use onboard propulsion to reach an operational altitude of 550 km, SpaceX said.

With a flat-panel design featuring multiple high-throughput antennas and a single solar array, each Starlink satellite weighs approximately 227 kg.

The satellites are equipped with star tracker navigation systems that allow SpaceX to pinpoint the satellites. They are also capable of tracking on-orbit debris and autonomously avoiding collision, according to SpaceX.

SpaceX founder Elon Musk said on a tweet that about 400 satellites will be needed to provide minor coverage and 800 for moderate coverage. The constellation is expected to grow to about 12,000 satellites by 2024.

New tariffs on Chinese goods increase costs for U.S. households study

(Xinhua)14:11, May 24, 2019

NEW YORK, May 23 (Xinhua) — The latest round of U.S. tariffs on Chinese goods will impose a total annual cost of 831 U.S. dollars for a typical U.S. household, according to a research posted Thursday on the Federal Reserve (Fed) Bank of New Yorks website.

The study was co-authored by Mary Amiti, assistant vice president in New York Feds research and statistics group, Stephen Redding, professor in economics at Princeton University, and David Weinstein, professor of the Japanese economy at Columbia University.

According to the research, increased tariffs in 2018 imposed an annual cost of 419 dollars for the typical U.S. household, with an added tax burden for consumers and a deadweight or efficiency loss as the two components.

The study also found that a 10 percent tariff reduced import demand by 43 percent.

The researchers estimated that the annualized deadweight loss will increase to 620 dollars per household with higher tariffs imposed.

In sum, according to our estimates, these higher tariffs are likely to create large economic distortions and reduce U.S. tariff revenues, according to the research.

Earlier this month, the United States increased additional tariffs on 200 billion U.S. dollars worth of Chinese imports from 10 percent to 25 percent, and has threatened to raise tariffs on more Chinese imports.

In response to the new round of U.S. protectionist moves, China has announced that it will raise additional tariffs on a range of U.S. imports from June 1, and will fight to the end. Enditem

U.S. tariffs on Chinese goods almost entirely borne by U.S. importers, says IMF study

(Xinhua)14:12, May 24, 2019

NEW YORK, May 23 (Xinhua) — U.S. tariff revenue collected from levies on Chinese goods has been borne almost entirely by U.S. importers, a study by the International Monetary Fund (IMF) has found.

The study, released on Thursday, said previously imposed tariffs have reduced trade between the United States and China, but the bilateral trade deficit remains broadly unchanged.

The study also said some of the additional tariffs have been passed on to U.S. consumers, while others have been absorbed by importing firms through lower profit margins.

Consumers in the U.S. and China are unequivocally the losers from trade tensions, the study said.

Earlier this month, the United States increased additional tariffs on 200 billion U.S. dollars worth of Chinese imports from 10 percent to 25 percent, and has threatened to raise tariffs on more Chinese imports.

In response, China has announced that it will raise additional tariffs on a range of U.S. imports from June 1, and will fight to the end.

A further increase in tariffs will likely be similarly passed through to consumers, the IMF study said.

While the impact on global growth is relatively modest at this time, the latest escalation could significantly dent business and financial market sentiment, disrupt global supply chains, and jeopardize the projected recovery in global growth in 2019.

U.S. farmers call for permanent solution, not just temporary aid

(Xinhua)14:13, May 24, 2019

CHICAGO, May 23 (Xinhua) — U.S. farmers on Thursday called for a permanent solution, not only temporary assistance, in response to the new trade aid package announced by the Trump administration.

The White House has authorized a second package to provide up to 16 billion U.S. dollars in assistance to farmers who are being impacted by the U.S. trade disputes with its major partners, the U.S. Department of Agriculture said on Thursday.

U.S. soy growers, who have been suffering from the ongoing trade disputes, welcomed the news but insisted that such trade assistance will only help in a short term.

A second round of financial support to offset farm losses is only a partial and temporary solution, and not a permanent solution for soy growers who have lost their number one export market … the American Soybean Association said in a statement on Thursday.

The U.S. National Corn Growers Association (NCGA) voiced their concerns about corn price drops and downbeat export outlook due to Washingtons trade disputes with China.

As trade talks with China lagged on in March and April of 2019, losses widened closer to 40 cents per bushel, the association said in a statement on Thursday too.

The NCGA recommended that the Trump administration provide both short-term assistance, support market access for farmers, and resolve trade disputes and tariffs.

The U.S. National Association of Wheat Growers (NAWG) also joined the call for a long-term solution.

The U.S. exports 50 percent of its wheat, which means we need a long-term solution, the NAWG said, urging Washington to complete negotiations with China and other trade partners.
