Pre-WW3 update, Russia putting S400 anti-aircraft missiles into Syria that can shoot 125 miles into Turkey

In an interview with Sputnik [a Russia propoganda site], former head of the Turkish General Staff's Intelligence Department Hakki Pekin condemned Turkey's decision to shoot down a Russian Su-24 bomber, describing it as a "big mistake."

Pekin suggested that Russia's response to the downing of the Su-24 will be very tough.

"Apart from sanctions, Russia also deployed its Iskander missile systems in Kaliningrad in retaliation against NATO's increasing activities. You have to understand that Russia has a very strong potential in this field," Pekin said.

Russia could use the information on ISIL selling oil via Turkish territory in order to have Turkey convicted by the International Court in The Hague.

CNN reports tensions in the Middle East ratcheted up dangerously Wednesday, a day after Turkey shot down a Russian warplane, with the Turkish President accusing Russia of deceit and Russia announcing it would deploy anti-aircraft missiles to Syria.

Russian Defense Minister Sergey Shoygu said on his ministry's Twitter feed that the country would deploy S-400 defense missile systems to its Hmeymim airbase near Latakia, on Syria's Mediterranean coast.

The missiles have a range of 250 kilometers, according to the website -- or 155 miles. The Turkish border is less than 30 miles away.

And Foreign Minister Sergey Lavrov told Russian TV on Wednesday that Russia has "serious doubts" that Turkey's downing of its warplane Tuesday was "an unpremeditated act."

"It looks very much like a planned provocation," Lavrov said.

Scaling Shock Electrodialysis for Desalination

A team at MIT has come up with an innovative desalination approach that, unlike most traditional desalination systems, does not separate ions or water molecules with filters, which can become clogged, or boiling, which consumes great amounts of energy.

Instead, the system uses an electrically driven shockwave within a stream of flowing water, which pushes salty water to one side of the flow and fresh water to the other, allowing easy separation of the two streams.

Membranes in traditional desalination systems, such as those that use reverse osmosis or electrodialysis, are “selective barriers,” Bazant explains: They allow molecules of water to pass through, but block the larger sodium and chlorine atoms of salt. Compared to conventional electrodialysis, “This process looks similar, but it’s fundamentally different,” he says.

In the new process, called shock electrodialysis, water flows through a porous material —in this case, made of tiny glass particles, called a frit — with membranes or electrodes sandwiching the porous material on each side. When an electric current flows through the system, the salty water divides into regions where the salt concentration is either depleted or enriched. When that current is increased to a certain point, it generates a shockwave between these two zones, sharply dividing the streams and allowing the fresh and salty regions to be separated by a simple physical barrier at the center of the flow.

Lawrence livermore has the highest peak power laser diodes in the world

Lawrence Livermore National Laboratory (LLNL; Livermore, CA) has the highest-peak-power laser-diode arrays in the world, which in total produce a peak power of 3.2 MW. The diode arrays, which were developed and fabricated by Lasertel (Tucson, AZ), will act as the primary pump source for the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS), currently under construction at LLNL.

An 800 kW laser-diode array developed and made at Lasertel is one of four such arrays that will pump the final power amplifier of the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) to be installed at the Extreme Light Infrastructure (ELI) Beamlines facility currently under construction in the Czech Republic.

HAPLS is designed to be capable of generating peak powers greater than one petawatt (1 quadrillion watts, or 10^15) at a repetition rate of 10 Hertz, with each pulse lasting 30 femtoseconds (30 quadrillionths of a second). This very high repetition rate will be a major advancement over current petawatt system technologies, which rely on flashlamps as the primary pump source and can fire a maximum of once per second. In HAPLS, the diode arrays fire 10 times per second, delivering kilojoule laser pulses to the final power amplifier. The HAPLS is being built and commissioned at LLNL and then installed and integrated into the ELI Beamlines facility starting in 2017.

The high repetition rate is possible because, unlike existing petawatt lasers, which are flashlamp-pumped, HAPLS is pumped by diode arrays capable of delivering kilojoule pulses at high repetition rates to the final power amplifier.

Each laser-diode array supplied by Lasertel supplied contains multiple 888 nm laser-diode bars mounted on water-cooled stacks (see figure). The array operates at a brightness of 10 kW/cm2, which Lasertel notes is a world record, at a repetition frequency of 10 Hz. Each array operates at a total peak power of 800 kW, with four such arrays combined and used as the primary pump sources for the HAPLS laser. More than 500,000 combined laser diode emitters combine to produce the total diode optical input power of 3.2 MW.

Largest diamond in a hundred years found

The Lucara Diamond Corporation, a Canadian company, said in a statement this week that the stone measures 1,111 carats, making it the biggest find in more than a century.

The 1,111 carat diamond is gem quality and is a Type IIa diamond.

The Royal Collection Trust, which oversees British royal treasures, says the largest diamond ever found was the 3,106-carat Cullinan diamond, unearthed in South Africa in 1905.

That diamond was cut into smaller pieces that are part of the crown jewels.

Lucara, which is based in Vancouver, says it also found two other large white diamonds in the same mine, Karowe, in Botswana. Those diamonds measure 813 carats and 374 carats.

Pre-WW3 update, Two of Turkey's F-16 shot down a Russian Su-24 fighter

Turkish warplanes shot down a Russian jet Tuesday after NATO-member Turkey says the plane violated its airspace on the border with Syria, a major escalation in the Syrian conflict that could further strain relations between Russia and the West.

Russian officials confirmed that a Russian Su-24 fighter had been shot down, but insisted it had not violated Turkish airspace.

“A stab in the back,” complained Russian President Vladi­mir Putin.

Turkey’s military, however, said that the Russian jet was warned multiple times before it was shot down by two F-16 fighter jets in the border zone in western Syria in mountains not far from the Mediterranean coast.

Bezos New Sheppard rocket lands after 60 mile suborbital space mission demonstrating reusability

Blue Origin’s New Shepard space vehicle successfully flew to space, reaching its planned test altitude of 329,839 feet (100.5 kilometers) before executing a historic landing back at the launch site in West Texas.

In the past, rockets were disposed of after launching space craft into outer space. Reusable rockets would substantially reduce the cost of space flight.

Some SpaceX rockets have landed upright in test flights that never left the atmosphere. But SpaceX's attempts to travel to outer space and return to upright landings have so far been unsuccessful. The rockets have toppled over while attempting to land on a platform in the ocean.

Blue Origin and SpaceX are two of the main players in the new business of private space launches. Another is Richard Branson's Virgin Galactic, which hopes to carry passengers to space in a vehicle launched from an airplane and that lands like a plane on a runway.

Bezos said he doesn't consider those companies Blue Origin competitors.
"I think of our competition primarily as Earth's gravity," he said. "Space is a big place. There's room for all of us."

Elon Musk tweeted congratulations to Bezos and Blue Origin early Tuesday. But he also took a dig at Blue Origin. Musk noted that rockets that reach the space station have to go 10 times as fast, and use 100 times the energy, of suborbital rockets that reach the edge of space as Blue Origin did.

"It is ... important to clear up the difference between 'space' and 'orbit,'" he tweeted.

Bezos said the part of the rocket (the first stage) that Musk is attempting to land is pretty much the same kind of spacecraft as Blue Origin's.

Bezos said this time his rocket performed exactly as planned, traveling into the edge of outer space before returning.
The rocket's engines reignited at 5,000 feet above ground to slow descent, and it was traveling at only 4.4 mph during its final 100 feet. It landed only 4-1/2 feet off the dead center of the the landing pad.

The space capsule on the top of the rocket that will someday carry space tourists separated from the rocket once it reached space and returned to Earth via parachute.

China may have made breakthroughs with aircraft carrier electromagnetic launch and railgun technology

China Aerospace Science and Industry Corporation (CASIC) and Office No. 206 of CASIC’s Second Institute has given priority to the research in electromagnetic launch of missile and phalanx close-in air defense and made unspecified breakthroughs.

The 206 Institute's hosted the Seventh Chinese Electromagnetic Technology Conference in Oct 2015, which also reported advances in material sciences to reduce railgun barrel wear

Phoenix Television reported on a number of other related railgun research advances. An early November 2015 news broadcast stated that Chinese researchers have made breakthroughs in electromagnetic aircraft launch systems (EMALS) and railguns, in areas from power storage to tougher barrel materials. EMALS catapults could be installed on Chinese aircraft carriers in the next decade, improving the performance of Chinese naval aircraft. The Phoenix TV broadcast also suggested that the PLAN hopes to test its own operational railgun in the next couple of years.

China putting $45.5 billion to start integrating Hebei province, Beijing and Tianjin

China on Friday earmarked 290 billion yuan ($45.45 billion) for manufacturing and industrial park projects to support its efforts to integrate Beijing, Tianjin and Hebei province into a megacity.

The government hopes to ease pressures on its crowded capital by transferring industries further out into the integrated metropolis, which it says has a combined population of about 110 million people. It dubbed the area "Jing-Jin-Ji" last year, using shortened versions of the names of the cities and province.

Companies that signed agreements with the three local governments and the Ministry of Industry and Information Technology for the 51 projects include Chinese server maker Inspur and carmaker Beiqi Foton Motor, the official China National Radio reported on its website.

By 2020, the population of eijing, Tianjin and Hebei province will likely be about 120 million

  • By 2025, Beijing will have over 7 million households earning over US$20,000 per year. This will make it third or fourth on the global rich cities list.
  • The Beijing mega-city is already happening. Beijing’s seventh ring road, currently under construction, is basically in Hebei at this point. And Tianjin is a fast 30-minute train ride away. So these cities are already connected in terms of hardware – roads, trains, and infrastructure. Now it’s about integrating the software - policies, companies, services, families, and so on.
  • The Beijing mega-city population is approximately 100 million people and this is rising fast. Between 1990 and 2010, Beijing’s population has grown more than three times as fast as China’s population. This is both from migrants and people having babies.
  • The economic output of the Jing-Jin-Ji cluster is about 10 per cent of China’s GDP. But by 2025, Beijing will be the world’s fifth largest urban economy. Add in Tianjin at number 12 and the Jing-Jin-Ji cluster will then be larger than London, Tokyo or New York.

Space telescopes launching in 2017 and 2018 will mean a lot more exoplanet discoveries and mearsuring their atmospheres

New space telescopes will be put up over the next few years to help with the search for planets outside our solar system.

The Transiting Exoplanet Survey Satellite (TESS) will discover thousands of exoplanets in orbit around the brightest stars in the sky. In a two-year survey of the solar neighborhood, TESS will monitor more than 200,000 stars for temporary drops in brightness caused by planetary transits. This first-ever spaceborne all-sky transit survey will identify planets ranging from Earth-sized to gas giants, around a wide range of stellar types and orbital distances. No ground-based survey can achieve this feat.

The Transiting Exoplanet Survey Satellite (TESS) is a planned space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method.

The primary mission objective for TESS is to survey the brightest stars near the Earth for transiting exoplanets over a two-year period. The TESS project will use an array of wide-field cameras to perform an all-sky survey. It will scan nearby stars for exoplanets

TESS will provide prime targets for further characterization by the James Webb Space Telescope, as well as other large ground-based and space-based telescopes of the future.

In order to obtain unobstructed imagery of both the northern and southern hemispheres of the sky, TESS will utilize a 2:1 lunar resonant orbit called P/2, a never-before-used orbit. The spacecraft's 373,000 km (232,000 mi) apogee is timed to keep the craft away from the Moon, which acts as a destabilizing agent. This highly elliptical orbit should remain stable for decades, and will keep TESS's cameras in a stable temperature range. The majority of the orbit is spent outside the Van Allen belts to avoid radiation damage to TESS. Every 13.7 days at its perigee of 108,000 km (67,000 mi), TESS will downlink the data it has collected during the orbit to Earth over a period of approximately three hours.

TESS's survey will focus on nearby G- and K-type stars with apparent magnitudes brighter than magnitude 12.Approximately 500,000 stars will be studied, including the 1,000 closest red dwarfs, across an area of sky 400 times larger than covered by the original Kepler mission. TESS is expected to discover more than 3,000 transiting exoplanet candidates, including those which are Earth sized or larger. Of those discoveries, an estimated twenty could be super-Earths located in the habitable zone around a star.

Exoplanet candidates could later be investigated by the Automated Planet Finder telescope, the HARPS spectrometer and both the future ESPRESSO spectrometer and James Webb Space Telescope.

The James Webb Space Telescope, set for launch in 2018, will be the first able to actually measure the atmospheric composition of a rocky, possibly Earthlike planet far off in space, and so vastly enhance the search for life.

DARPA seeking novel mathematical frameworks for understanding and representing complexity

Complex interconnected systems are increasingly becoming part of everyday life in both military and civilian environments. In the military domain, air-dominance system-of-systems concepts, such as those being developed under DARPA’s SoSITE effort, envision manned and unmanned aircraft linked by networks that seamlessly share data and resources in real time. In civilian settings such as urban “smart cities”, critical infrastructure systems—water, power, transportation, communications and cyber—are similarly integrated within complex networks. Dynamic systems such as these promise capabilities that are greater than the mere sum of their parts, as well as enhanced resilience when challenged by adversaries or natural disasters. But they are difficult to model and cannot be systematically designed using today’s tools, which are simply not up to the task of assessing and predicting the complex interactions among system structures and behaviors that constantly change across time and space.

To overcome this challenge, DARPA has announced the Complex Adaptive System Composition and Design Environment (CASCADE) program. The goal of CASCADE is to advance and exploit novel mathematical techniques able to provide a deeper understanding of system component interactions and a unified view of system behaviors.
