Beijing: China on Thursday launched its first Dark Matter Particle Explorer (DAMPE) satellite in a fresh search for smoking-gun signals of the invisible material that scientists believe makes up most of the universe’s mass.

The DAMPE satellite, nicknamed “Wukong” after the Monkey King with penetrating eyes in the Chinese classical fiction “Journey to the West”, blasted off on Thursday morning on a Long March 2-D rocket from the Jiuquan Satellite Launch Centre in Gansu province, Xinhua news agency reported.

It will enter a sun-synchronous orbit at a height of 500 km to observe the direction, energy and electric charge of high-energy particles in space.

From there, scientists hope the 1.9-tonne desk-sized satellite could help raise the “invisible cloak” on the dark matter and shine more light on the hypothetical mass.

With the new DAMPE satellite, scientists will look for evidence of dark matter annihilation or decay.

Wukong will scan the space in all directions in the first two years and focus on sections where dark matter are most likely to be observed afterwards.

More than 100 scientists will study the data sent back by Wukong. Initial findings are expected to be published in the second half of 2016.

Dark matter, which does not emit or reflect enough electromagnetic radiation to be observed directly, is one of the huge mysteries of modern science.

Theorised by scientists who could not understand missing mass and strangely bent light in faraway galaxies, dark matter has become widely accepted in the physics community even though its existence has never been concretely proven.

Scientists now believe only around five percent of the total mass-energy of the known universe are made up of ordinary matter, whereas dark matter and dark energy make up the rest.

Knowing more about dark matter could hence give humanity a clearer idea about the past as well as future of galaxies and the universe, and will be revolutionary for the world of physics and space science. (IANS), (image courtesy: space.com)

China And Russia Accused of Manipulating Their Currencies By Trump

Donald Trump to accuse China and Russia as their currency manipulators

U.S. President Donald Trump said on Monday it is unacceptable that Russia and China are devaluating their currencies, days after the Treasury Department declined to label these countries as currency manipulators in its latest report.

Amid a possible new round of sanctions against Russia and a simmering trade war with China, Trump tweeted Monday morning, “Russia and China are playing the Currency Devaluation game as the U.S. keeps raising interest rates. Not acceptable!

In general, when a country artificially devaluates its currency, its exports become cheaper and more competitive in the global marketplace.

During his presidential campaign, Trump has repeatedly accused China of lowering the value of its currency and vowed to formally label China as a currency manipulator, but so far has failed to do so.

White House Press Secretary Sarah Sanders says the administration is closely watching China’s currency practices. “That’s something that the Treasury Department is watching very closely and we’re continuing to monitor it,” she said Monday.

In a semiannual report titled “Macroeconomic and Foreign Exchange Policies of Major Trading Partners of the United States” released last Friday, the Treasury Department did not designate China as a currency manipulator, but put it as one of the six countries on a monitoring list. The other five countries on the list are Japan, Korea, India, Germany, and Switzerland. Russia is not on the monitoring list. The Chinese currency, the renminbi, has appreciated over 3 percent against the dollar since the beginning of this year, after strengthening by over 6 percent in 2017.

Brad Setser,a senior fellow at the Council on Foreign Relations and a former Treasury Department official said in an interview with VOA he does not think it is an accurate complaint that Russia and China are playing the currency game.

“The Russian ruble was actually quite stable before the sanctions on Russia were intensified. It’s quite clear the volatility in the ruble is a function of the intensification of U.S. sanctions, a sign that the sanctions are biting,” he explained.

Setser said over the past several months, the Chinese yuan has actually appreciated, and China has not been intervening heavily.

“There are plenty of things to criticize China for on trade, but right now, there’s no real basis for criticizing China on currency,” he noted.

In the past three years, the Federal Reserve raised interest rate six times to a range between 1.5 percent and 1.75 percent, and said they expect to raise the rate two or three more times this year.

Usually, when a country raises its interest rates, the value of its currency rises, making its exports more expensive and less competitive. However, higher U.S. interest rates have not raised the value of the dollar.

“The interesting puzzle that the market has been pondering for the past several months is that the dollar has actually weakened even as the U.S. has raised rates, and even as U.S. passed legislation to expand the fiscal deficit,” Setser said.

Former Deputy Assistant Secretary for International Economic Analysis at the Treasury Department Setser stressed the United States should not label China as a currency manipulator at this moment.

“It would undermine the United States’ credibility to name China at a point in time when there is no plausible case that China is managing its exchange rate in a way that is adverse to the U.S. interest,” he said.  VOA
