JIUQUAN/BEIJING, Nov. 1 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced early Tuesday that the launch of Shenzhou-8 unmanned spacecraft was successful.The spacecraft was sent into the designated orbit after the blastoff at 5:58 a.m. from the Jiuquan Satellite Launch Center in northwest Gobi desert, carried by an upgraded Long March-2F rocket.It is heading for rendezvous with Tiangong-1, or "the Heavenly Palace" that was put into space on Sept. 29 for the country's first space docking.The move, if successful, will pave the way for China to operate a permanent space station around 2020 and make the nation the world's third to do so.The combined photo taken on Nov. 1, 2011 shows the blast-off of a modified model of the Long March CZ-2F rocket carrying the unmanned spacecraft Shenzhou-8 at the Jiuquan Satellite Launch Center in northwest China's Gansu Province. Commander-in-chief of China's manned space program Chang Wanquan announced that the launch of the spacecraft was successful.Chinese Vice Premier Zhang Dejiang viewed the launch at the Jiuquan center. The launch was also observed on site by senior officials from the European Space Agency and the German Aerospace Center.The docking is scheduled to occur within two days after the launch of Shenzhou-8 and at a height of 343 km above the Earth's surface. It will return to the Earth after two docking tryouts.Chinese and German scientists will conduct 17 life science space experiments on the Chinese spacecraft Shenzhou-8, Wu Ping, spokeswoman for China's manned space program, said Monday.To ensure the success of the mission, Chinese space engineers have made "considerable modifications" on Shenzhou-8 to previous versions of the spacecraft.Shenzhou-8, with a length of nine meters and a maximum diameter of 2.8 meters, has a liftoff weight of 8.082 tonnes."More than half of the 600 or so sets of equipment have been modified, while newly designed devices account for about 15 percent of the total," Wu said.The modifications were mainly aimed at arming the spacecraft with automatic and manual rendezvous and docking capacities, and enhancing the vehicle's performance, safety and reliability, Wu said."After the improvements, the spacecraft will be able to connect with the target spacecraft Tiangong-1 for 180 days," Wu said.The unmanned spacecraft is also equipped with devices for recording real images and mechanical parameters during its flight, to test the space docking before a manned attempt.Once China has mastered the technologies of rendezvous and docking, it will be equipped with the basic technologies and capacity required for building a space station, said Zhou Jianping, chief designer of China's manned space program.Tuesday's mission will be followed by launches of spaceships Shenzhou-9 and -10 in 2012, which are also expected to dock with Tiangong-1. "At least one mission of the two will be manned," Wu said.The crew members, including probably two female astronauts, have already been selected for the possible manual space docking mission in 2012 and are being trained for manual docking skills.The space docking tests and experiments will provide crucial experience of China's construction of a 60-tonne permanent manned space station around 2020 when Chinese astronauts are expected to operate more research projects in space."It will make it possible for China to carry out space exploration of a larger scale," Zhou said.

BEIJING, Jan. 5 (Xinhua) -- The U.S. Secretary of Treasury Timothy Geithner will visit China from Jan. 10 to 11 as a special representative of the U.S. President Barack Obama, Chinese Foreign Ministry spokesman Hong Lei announced on Thursday.Timothy Geithner's visit is at the invitation of Chinese Vice Premier Wang Qishan, said Hong.Chinese top leaders will meet with Timothy Geithner and exchange views with him on issues concerning Sino-US economical relations and the world's economic and financial situations, Hong said.

ting fuel and benefits to agriculture from extended growing seasons."Global mitigation leading to a low climate change future reduces costs to Canada in the long term. This reinforces the argument that Canada would benefit environmentally and economically from a post 2012 international climate arrangement that systematically reduced emissions from all emitters - including Canada - over time," the report says.It recommends cooperation between governments, scientists and businesses to find ways to mitigate climate change and adapt to it.Canada's Minister of the Environment Peter Kent said the government has a plan to deal with global warming issues, which will be announced next month."Our government has a plan, a very good plan, to meet our target of reducing greenhouse gases by 17 percent from 2005 base levels, by 2020," Kent told Canada's House of Commons Thursday afternoon."We are moving forward to reduce greenhouse gases and, at the same time, we are investing in programs to help Canadians adapt to climate change," Kent said."Today's report merely echoes what our government has long recognized; that is, the importance of adaptation to climate change," he added.Earlier this week, several hundred people protested the government's policy of exploiting the oil sands deposits in western Canada.Environmentalists have criticized the Canadian government for not working hard enough to reduce CO2 emissions. Last year, a coalition of global warming activists gave Canada the "Fossil of the Year" award for failing to implement the Copenhagen Accord.

WASHINGTON, Dec. 22 (Xinhua) -- The journal Science on Thursday chose the HPTN 052 clinical trial, an international HIV prevention trial as the 2011 Breakthrough of the Year.The study found that if HIV-infected heterosexual individuals begin taking anti-retroviral medicines when their immune systems are relatively healthy as opposed to delaying therapy until the disease has advanced, they are 96 percent less likely to transmit the virus to their uninfected partners. Findings from the trial, first announced in May, were published in the New England Journal of Medicine in August.The study was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health."The HPTN 052 study convincingly demonstrated that anti- retroviral medications can not only treat but also prevent the transmission of HIV infection among heterosexual individuals," said NIAID Director Anthony Fauci in a statement. "We are pleased that Science recognized the extraordinary public health significance of these study results."Science's list of nine other ground-breaking scientific achievements from 2011 include:The Hayabusa Mission: After some near-disastrous technical difficulties and a stunningly successful recovery, Japan's Hayabusa spacecraft returned to Earth with dust from the surface of a large, S-type asteroid. This asteroid dust represented the first direct sampling of a planetary body in 35 years, and analysis of the grains confirmed that the most common meteorites found on Earth, known as ordinary chondrules, are born from these much larger, S-type asteroids.Unraveling Human Origins: Studying the genetic code of both ancient and modern human beings, researchers discovered that many humans still carry DNA variants inherited from archaic humans, such as the mysterious Denisovans in Asia and still-unidentified ancestors in Africa. One study this year revealed how archaic humans likely shaped our modern immune systems, and an analysis of Australopithecus sediba fossils in South Africa showed that the ancient hominin possessed both primitive and Homo-like traits.Capturing a Photosynthetic Protein: In vivid detail, researchers in Japan have mapped the structure of the Photosystem II, or PSII, protein that plants use to split water into hydrogen and oxygen atoms. The crystal-clear image shows off the protein's catalytic core and reveals the specific orientation of atoms within. Now, scientists have access to this catalytic structure that is essential for life on Earth -- one that may also hold the key to a powerful source of clean energy.Pristine Gas in Space: Astronomers using the Keck telescope in Hawaii to probe the faraway universe wound up discovering two clouds of hydrogen gas that seem to have maintained their original chemistry for two billion years after the big bang. Other researchers identified a star that is almost completely devoid of metals, just as the universe's earliest stars must have been, but that formed much later. The discoveries show that pockets of matter persisted unscathed amid eons of cosmic violence.
