First element discovered in Asia named ‘nihonium’, after Japan

TOKYO: Japanese scientists behind the discovery of element 113, the first atomic element found in Asia — indeed, the first found outside Europe or the United States — have dubbed it "nihonium" after the Japanese-language name for their country.

"I believe the fact that we, in Japan, found one of only 118 known atomic elements gives this discovery great meaning," said Kosuke Morita, a university professor who led the discovery team from the RIKEN Nishina Center for Accelerator-Based Science.

"Another important meaning is that until now, all the elements in the periodic table have been discovered in Europe and the United States," he told a news conference on Thursday.

"There has not been a single atomic element found in Asia, Oceania or Africa."

Element 113 was first found in 2004, and the number refers to its atomic number, or the number of protons in the nucleus of the atom. It does not exist naturally and has had to be synthesised.

Though the element was publicly recognised by the International Union of Pure and Applied Chemistry (IUPAC) in December 2015, the name was not announced by IUPAC until Wednesday. It will become permanent after a five-month public review.

If approved, it will join other newly announced elements: moscovium for element 116, tennessine for element 117 and oganesson for element 118.

It will also not be the only element to be named after a country, having been preceded by polonium and francium after the places they were discovered. — Reuters Source: http://www.tribuneindia.com/

China launches spacecraft in longest-ever manned mission

The Shenzhou 11 astronauts are Jing Haipeng, who is flying his third mission, and 37-year-old Chen Dong.
The Shenzhou 11 mission took off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert in northern China. China launched a pair of astronauts into space Monday on a mission to dock with an experimental space station and remain aboard for 30 days in preparation for the start of operations by a full-bore facility six years from now. The Shenzhou 11 mission took off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert in northern China at 7:30 a.m. (2330 GMT) aboard a Long March-2F carrier rocket. It will dock with the Tiangong 2 space station precursor facility within two days, conduct experiments in medicine and various space-related technologies, and test systems and processes in preparation for the launching of the station's core module in 2018. Space program commander-in-chief Gen. Zhang Youxia declared the launch a success at 7:46 a.m. (2346 GMT). Defense Minister Fan Changlong then read a congratulatory message from President Xi Jinping calling for China's astronauts to explore space "more deeply and more broadly." Premier Li Keqiang and propaganda chief Liu Yunshan visited the Beijing control center to congratulate staff. It is the sixth time
China has launched astronauts into space and the duration will be the longest by far. Following the attachment of two experiment modules, the completed station is set to begin full operations in 2022 and will run for at least a decade. An earlier Tiangong 1 experimental space station launched in 2011 went out of service in March after docking with three visiting spacecraft and extending its mission for two years. The Tiangong, or "Heavenly Palace," stations are considered stepping stones to a mission to Mars by the end of the decade. The Shenzhou 11 astronauts are Jing Haipeng, who is flying his third mission, and 37-year-old Chen Dong. "It is any astronaut's dream and pursuit to be able to perform many space missions," Jing, who turns 50 during his time in space, told a briefing Sunday. China conducted its first crewed space mission in 2003, becoming only the third country after Russia and the U.S. to do so, and has since staged a spacewalk and landed its Yutu rover on the moon. Administrators suggest a crewed landing on the moon may also be in the program's future. China was prevented from participating in the International Space Station, mainly due to US concerns over the Chinese space program's strongly military character. Chinese officials are now looking to internationalize their own program by offering to help finance other countries' missions to Tiangong 2. China's space program also opened its massive fourth spacecraft launch site at Wenchang on China's southernmost island province of Hainan in June. It was inaugurated with the launch of the newly developed Long March 7 rocket that was hailed as a breakthrough in the use of safer, more environmentally friendly fuels. China is currently developing the Long March 5 heavy-lift rocket needed to launch the Tiangong 2's additional components and other massive payloads. China also plans to land a rover on Mars by 2020, attempting to recreate the success of the US Viking 1 mission that landed a rover on the planet four decades ago. A source of enormous national pride, China's space program plans a total of 20 missions. (This story first appeared in Deccan Chronicle) Source: The Asian Age
