China has huge potential for combustible ice resources: experts

China has for the first time succeeded in mining flammable ice at sea, after nearly two decades of research and exploration, the country’s Ministry of Land and Resources announced on May 18. Experts also pointed out that these are only a small portion of China’s huge reserves.

Trial mining of combustible ice in the Shenhu Sea, about 320 kilometers southeast of Zhuhai, Guangdong province, began on March 28. Experts first tapped the natural hydrate at a depth of 1,266 meters underwater last Wednesday. After that, an average of 16,000 cubic meters of gas with high purity were extracted each day.

Ore bodies of 11 combustible ice types have been found, and the estimated reserves are equal to 150 billion cubic meters. Chinese scientists also estimate that there is an area of 5,242 square kilometers of combustible ice in the Xisha Trough. In other waters of the South China Sea, experts predict the existence of more natural gas hydrate.

China’s successful operation is groundbreaking. Other countries like the U.S., Canada and Japan are conducting research to arrive at the same results, but China’s achievement means its technology in this area is among the best, according to Xie Wenwei, deputy director of the command office at the exploration site.

Combustible ice usually exists in seabeds or tundra areas, which have the strong pressure and low temperatures necessary for the ice’s stability. One cubic meter of combustible ice is equal to 164 cubic meters of regular natural gas.

The mining of combustible ice started in the 1960s, but China began its research in 1998. The country first found flammable ice in the South China Sea in 2007.

China to build global navigation satellite system by 2020

China plans to build a global navigation satellite system, which is expected to provideservice to users around the world, by the year 2020.

The country will send six to eight satellites to space later this year, and it will have 18satellites in space by 2018 to provide basic services to countries along the “Belt and Road”route, disclosed Wang Li, China Satellite Navigation System Committee chairman, at the8th China Satellite Navigation Conference on May 23.

The BDS-1 and BDS-2 systems, also known as BeiDou Navigation Satellite DemonstrationSystem, were built in 2000 and 2012 respectively, providing communication services toChinese and other Asian users, said Ran Chengqi, director of China’s Satellite NavigationSystem Management Office. The BDS-3 system will broadcast additional navigation signalsand enhance compatibility with other navigation satellite systems so as to provide betterservice for global users, Ran added.

Clinical tests to be launched for therapeutic leukemia vaccine

Clinical tests for a therapeutic leukemia vaccine will be carried out this year, according toinformation released at the 2017 International Forum on Precision Medicine andTranslational Medicine. The vaccine is expected to raise the five-year survival rate ofleukemia patients by as much as 20 percent.

Leukemia, also known as blood cancer, is a vicious disease originating from stem cells. Thedisease occurs in about four in 100,000 people, with approximately 40,000 new patientsevery year in China.

According to Li Yuhua, director of the hematology department at Zhujiang Hospitalaffiliated with Southern Medical University, the therapeutic vaccine is for patients whopossess tumors. Chemotherapy helps most leukemia patients, but the best method toprevent relapse is transplantation. However, transplant surgeries are very expensive, andchemotherapy is the only choice for patients who have relapsed after receiving atransplant.

The vaccine was mainly developed for low to mid-risk leukemia patients, such as thosewho can’t withstand chemotherapy and those still in need of relief after receivingchemotherapy. Compared with transplants, which can cost hundreds of thousands of RMBfor one treatment course, the vaccine offers a cost-effective choice.

Though the vaccine can reduce the length of chemotherapy, Li emphasized thatchemotherapy is still the primary treatment for leukemia. Li told the Southern Daily thatclinical tests of the vaccine will be carried out simultaneously in seven hospitals this year. Itis expected to improve the five-year survival rate of leukemia patients by 10 to 20percent, which means that 10 to 20 percent more patients will be able to fully recover.

China rolls out measures to regulate drone market

Unmanned aerial vehicles weighing more than 250 grams will have to go through aregistration process, according to the civil drone registration system instituted by the CivilAviation Administration of China (CAAC).

The system officially began operation on May 18, and it will come into force on June 1.CAAC also announced protective zones around 155 airports, so as to prevent flights frombeing affected by drones.

Unmanned aerial vehicles have caused flight interferences at multiple airports in the past.On May 12, flights leaving southwestern China’s Chongqing Municipality were disruptedwhen several unregistered drones suddenly appeared on airstrips, affecting over 100planes.

Experts warned that drones can cause injuries when they fall from the sky, andunregulated drones can cause private information to be leaked. They therefore suggest anintegrated rule to regulate the production and operation of drones.

Domestic demand for drones is growing by 50 percent annually, set to yield a total marketvalue of 75 billion RMB ($11 billion) by 2025.

China, Russia develop superjet C929, to compete with Boeing’s 787 Dreamliner

A joint project between China and Russia to build a C929 superjet is currently progressingsmoothly through research and development, according to Jin Zhuanglong, chairman of theCommercial Aircraft Corporation of China (COMAC).

The fuel-efficient plane will reportedly compete with Boeing’s 787 Dreamliner. Though notthe biggest passenger jet in terms of size, both the C929 and the Dreamliner are capable ofa wide range of use, and both are relatively economical, according to data.

China’s civilian aircraft industry is pressing ahead as planned, allowing a next-generationjet to benefit from earlier research and manufacturing know-how. The new aircraft willalso obtain an airworthiness certificate from its predecessor, industry insiders pointed out.

In June 2016, Russia’s United Aircraft Corporation (UAC) and COMAC signed amemorandum of understanding on the manufacturing of a wide-body long-range aircraft.According to the agreement, UAC will supply its most advanced avionics technology and acutting-edge composite wing. China will handle the C929 fuselage construction, withShanghai-based COMAC set to assemble the jets.

UPDATE:

On May 22, the China-Russia Commercial Aircraft International Corporation Ltd. (CRCAIC) was established in Shanghai, a joint venture between Commercial AircraftCorporation of China (COMAC) and Russia’s United Aircraft Corporation (UAC). The jointventure will be principally engaged in the development of the next generation of long-distance wide-body aircraft.

The two sides have confirmed a series of development programs for the long distancewide-body aircraft, completed the preliminary definition of level indicators for the aircraft,and defined the range (12,000 km) and number of seats (280). The project is now in itsinitial design stage, and system and equipment suppliers will be inquired.

A Robot Just Landed a Simulated Boeing 737, So What Next for Air Travel?

Aviation has not had the best PR over recent months, and with disasters such as that of United Airlines vs. 69-year-old grandfather, passengers are starting to doubt whether flying is worth it all.

The following news may, however, lift the spirits of — or further terrify — frequent flyers around the world: a robot has successfully landed a Boeing 737.

Aurora Flight Sciences, which developed the robot, are bursting with pride according to sources, as the bot was able to sit in the co-pilots seat and land the simulated plane.

This has lead the Defense Advanced Research Projects Agency (DARPA), part of the US Department of Defense team responsible for the development of emerging technologies for use by the military, to advocate the use of robots in their planes.

With DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program, the military have evolved to incorporate automated capabilities, improving mission safety and success rates.

However according to DARPA, operators of the most automated aircraft must still manage daunting and complex interfaces and be prepared to respond effectively in emergencies and other unexpected situations that no amount of training can prepare them for.

The military will often find themselves in stressful situations and are keen to use systems that have the potential to interact with the crew; it is for this reason that the use of robots in the cockpit is becoming a highly likely option.

This is where Aurora’s newly developed bot comes in, the machine is able to control the advanced tablet-based user interface and works off speech recognition.

Aurora’s done this before in an actual flight, but for light aircraft. Simulating a 737 landing gets it closer to ALIAS’ goal of adding a helping hand to crews of large military aircraft and potentially even using robots in passenger planes.

The technology still has come way to go, but Aurora Flight Sciences and DARPA hope that it could be beneficial for military flights and sources claim that the future for passenger planes could also be in robots’ hands.

Could Humans Live on the Closest Planet Outside Our Solar System?

A new study of Proxima b, the closest planet outside our solar system ever discovered, suggests that the planet may actually be able to support life of its own.

After decades of searching, astronomers finally discovered a planet in Alpha Centauri, our neighboring star system, in August 2016. Proxima b is a bit larger than the Earth but orbits much closer to its star, the red dwarf Proxima Centauri. Since red dwarfs give off much less heat than yellow stars like our sun, planets can be very close to them and still be within their star’s “habitable zone.”

Proxima b is in its star’s habitable zone, meaning it could support liquid water. That, combined with its closeness to Earth, makes it an object of inspiration for human astronomers dreaming of the future.

But some have doubted Proxima b’s habitability. Many factors are involved: for instance, Proxima b’s closeness to its star may have stripped it of its atmosphere.

A new study from the University of Exeter in the United Kingdom, which was published in the journal Astronomy & Astrophysics, applied a new model previously used to study Earth’s climate patterns to Proxima b. This model, the Met Office Unified Model, was adapted to model the climate history of Proxima b.

Since we don’t yet know what Proxima b’s atmosphere is made of, the Exeter team ran the simulation twice: once with a Proxima b that has an Earth-like atmosphere (mostly nitrogen and oxygen, with some argon and carbon dioxide and traces of other gases), and again with a Proxima b with a simple atmosphere (just nitrogen and some carbon dioxide).

Because Proxima b is so close to its star, it’s likely hit by massive quantities of radiation. This can have adverse effects on a planet’s atmosphere, such as breaking it down entirely. It can also act as a food source for primitive life.

“Overall, our results are in agreement with previous studies in suggesting Proxima Centauri b may well have surface temperatures conducive to the presence of liquid water,” the team wrote. There’s an excellent chance that the planet is “likely to be habitable for a range of orbital states and atmospheric compositions.”

Of course, the simulation is just that: a model. Human observation of Proxima b has been done from trillions of miles away, and we know far less about it than we can know about a planet we can observe directly with orbiting instruments.

“There are obviously several ingredients missing from our analysis,” the Exeter team wrote. “We have neglected the presence of any land-surface, as we have no information what this may look like.”

Russia’s First Missile Defense Airship to Be Produced in Three Years

Russia’s experimental airship Atlant is scheduled to make its first flight somewhere in late-2020, NSN news service reported, citing Augur-RosAeroSystems CEO Gennady Verba.
Gennady Verba said that the final version of the Atlant airship would take about 3.5 years to build at the cost of several billion rubles.

He added, however, that the other modifications would cost less.

During a news conference at the National News Service headquarters on Tuesday, Verba thanked the Skolkovo Fund for helping develop the airship’s autonomous ballast system, which allows the airship to float freely in a horizontal position and, whenever necessary, to lose its lift and descend.
The Atlant multifunctional airship will come in two versions: Atlant 100, capable of hauling up to 60 tons of cargoes 2,000 kilometers away, and Atlant 30 with a cargo-carrying capacity of up to 16 tons.

The Atlants will also be integrated into the national early warning system.

Airships theoretically have infinite endurance, owing to the fact that they do not need forward speed to maintain lift.

They do not need runways and can carry vast amounts of payloads over long distances nonstop. They are also very fuel efficient and highly reliable.

On the downside, with a maximum speed of just 160 kilometers an hour (90 miles an hour) the airships are extremely slow, as compared to modern jets.

Their greatest disadvantage is size, which is essential to increasing performance. As size increases, the problems of ground handling increase geometrically.
Still, despite these drawbacks, airships do remain viable in some domains.

Aviation experts believe that with developments in the field of dirigible construction, airships could eventually become an indispensable element of Russia’s air transportation system and become its new trademark.
