China launched satellite in search for Dark Matter

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’s Economy Slows As It Tries to Diffuse Trade War With U.S.A.

The impact on China’s economy from the Sino-U.S. trade frictions are not apparent yet, Mao cautioned, adding that the nation will face more “external” uncertainties in 2019.

China’s November retail sales grew at their weakest pace since 2003 and industrial output rose the least in nearly three years as domestic demand softened further, underlining rising risks to the economy as China works to defuse a trade dispute with the United States.

The world’s second-largest economy has been loosing momentum in recent quarters as a multi-year government campaign to curb shadow lending put increasing financial strains on companies in a blow to production and investment.

The slowdown in Chinese industries has started to weigh on consumer sentiment this year, tapping the brakes on retail sales. Big-ticket items have been the first to be hit, with auto sales declining since May.

Pace of retail sales slows

Retail sales rose 8.1 percent in November from a year earlier, data from the National Bureau of Statistics showed Friday, below expectations for an 8.8 percent rise and the slowest since May 2003. In October, sales increased 8.6 percent. Auto sales fell a sharp 10.0 percent from a year earlier.

The slump was in line with data released by China’s top auto industry association, which showed sales dived 14 percent in November, the steepest drop in nearly seven years.

The stresses on broad activity have been compounded by a sharp escalation in China’s trade dispute with the United States, which has threatened to fracture global supply chains, chill investment, exports and growth.

Pace of industrial output slows

Industrial output rose 5.4 percent in November, missing analysts’ estimates and matching the rate of growth seen in January-February 2016. Factory output had been expected to grow 5.9 percent, unchanged from October’s pace.

Over the weekend, China reported far weaker than expected November exports and imports, reflecting slower global demand and waning domestic factory activity as profit margins narrow.

With economic growth at its weakest since the global financial crisis, Chinese policymakers are ramping up spending, pushing banks to increase lending and cutting taxes to shore up businesses and ward off a more damaging slump.

The weaker November industrial output and retail sales growth numbers showed that downward pressure on the economy is increasing, said Mao Shengyong, spokesman at the statistics bureau.

Still on track to hit growth target

But China is on track to hit its 2018 economic growth target of around 6.5 percent, Mao told reporters.

“On balance, the latest data show an economy that is under pressure on both the external and domestic front, with policy efforts to shore up growth still falling short,” Julian Evans-Pritchard, senior China economists at Capital Economics, wrote in a note.

A temporary 90-day trade war truce agreed by the United States and China early this month may have removed some of the immediate pressure on the economy.

The impact on China’s economy from the Sino-U.S. trade frictions are not apparent yet, Mao cautioned, adding that the nation will face more “external” uncertainties in 2019.

Indeed, even in the unlikely event the world’s top two economies reach a durable resolution in their dispute, ebbing domestic demand, mounting household debt and a cooling real estate sector point to a further slowdown in growth next year. (VOA)
