BEIJING, Sept. 21 (Xinhuanet) -- China will launch an unmanned module next week, paving the way for a planned space station, a spokesman for the space program said on Tuesday.Tiangong-1, or "Heavenly Palace 1", will blast off from Jiuquan Satellite Launch Center in Gansu province between Sept 27 and 30, the spokesman said.The 8.5-ton module, and the Long March II-F rocket that will carry it skyward, were positioned onto the launch pad on Tuesday, signaling that the project has entered the final preparation stage."Scientists will conduct final tests in the next few days before injecting propellants for the launch," Cui Jijun, director of the Jiuquan Satellite Launch Center, said.The program spokesman said that Tiangong-1 will serve as "a target spacecraft" for rendezvous and docking experiments.It will also work as "a platform to test long-term unmanned and short-term manned operations", he said.Technical and medical experiments will provide crucial data ahead of the building of the space station (scheduled for 2020).Three rendezvous and docking experiments will be conducted.An unmanned Shenzhou-VIII craft will be launched later this year to dock with Tiangong-1. In 2012, Shenzhou IX and Shenzhou X will blast off to complete at least one manned docking.Jiao Weixin, a space scientist at Peking University, said that rendezvous and docking - vital maneuvers for manned programs - are hard to master."Rendezvous and docking are difficult because it is like asking two racing cars to keep a distance of 1 meter between them," he said.The mission requires two craft, traveling at speeds of 28,000 km/h, to enter the same orbit and connect with precision, he said.The China Manned Space Engineering Office rescheduled the launch of Tiangong-1 after the failed launch of an experimental orbiter last month.The spokesman said that the carrier rocket to blast off with Tiangong-1 atop has been modified.Only the United States and Russia have mastered rendezvous and docking technology, said Pang Zhihao, deputy editor-in-chief of the magazine Space International.Spacecraft developed by Europe and Japan have utilized US and Russian technology to dock with the International Space Station, he added.

BEIJING, Sept. 27 (Xinhuanet) -- Last-minute preparations for the launch of the Tiangong-1 spacecraft began at the Jiuquan Satellite Launch Center on Monday, meaning the vehicle can soon embark on a mission that will eventually have it dock with a spaceship, according to the center.That feat, if carried out successfully, will mark the completion of China's first rendezvous and docking mission.At the launch site on Monday afternoon, crews were putting in place pipes and cables that will be used to inject fuel into the rocket that will carry Tiangong-1 into outer space.Without complications from the weather or other causes, the Long March II-F rocket will lift off from the launch center on Thursday or Friday, taking the Tiangong-1 with it, according to the Xinhua News Agency.Despite the preparations, space experts said carrying out the plan still comes with many risks. They explained that the spacecraft and much of the other equipment being used is new and has not been tried on an actual mission."Tiangong-1 is a brand new spacecraft designed by China and is bigger and heavier than the Shenzhou spaceships China had developed as a means of transporting astronauts from the Earth to space," said Yang Hong, chief designer of Tiangong-1.In a vertical position, the Tiangong-1 looks like a cigar standing 10.4 meter tall, a height equal to that of a three-story building. It weighs 8.5 tons and has a maximum diameter of 3.35 meters, a dimension shared by its launch vehicle, he said.In comparison, the Shenzhou spaceship stands shorter, at nearly 9 meters, is slimmer, having a diameter of less than 3 meters, and weighs less.In another difference, the Tiangong-1 is composed of two modules rather than the three that had made up the Shenzhou spaceship. Of the Tiangong-1's two primary components, one is an experimental module that contains a place that astronauts can live and work in on future missions. It is also equipped with a docking port.The other chief component, a resource module, will provide the craft with power.Astronauts on Tiangong-1 will have 15 cubic meters of space to move in, "much more than they had in the Shenzhou spaceship", Yang said.Inside the spacecraft are two sleeping sections with adjustable lighting systems, exercise equipment, entertainment systems and visual communication devices, he said.Hou Xiangyang, who helped design Tiangong-1, said: "The sleeping section is big enough for a 1.8-meter-tall man to sleep in. An astronaut can adjust the light as he likes."In space, Tiangong-1 will fly in a horizontal position. A paint scheme inside will help the astronauts aboard maintain their sense of direction; the module's inner walls will be in two colors, one commonly associated with the sky and one with the ground."This will help astronauts avoid feeling as if they are standing upside down in the microgravity environment," he said.Yang said the Tiangong-1 spacecraft is expected to stay in orbit for two years and rendezvous and dock with three different spaceships. Beyond the Shenzhou VIII, ships named Shenzhou IX and Shenzhou X will embark on similar missions; at least one of the two is to be manned.Before astronauts climb on board Tiangong-1, the conditions inside its experimental module will be adjusted to ensure they can live in an environment that contains enough oxygen, moisture and heat to be safe.Tiangong-1 was originally scheduled to be launched into a low orbit around the Earth between Sept 27 and 30. The earlier days were removed as possible launch dates, though, after forecasters predicted a cold air mass would move into the area containing the Jiuquan Satellite Launch Center.To ensure the spacecraft and Long March II-F carrier rocket are ready for launch, a full ground simulation was conducted on Sunday afternoon.

MOSCOW, Aug. 30 (Xinhua) -- Russia's space agency said Tuesday that a Proton-M rocket launch failed earlier this month because of a malfunction in the upper stage.The conclusion was reached by an independent investigation commission following a series of checks, Roscosmos said in a report that was posted on its website."The commission reported that the time span reserved for the gyrostabilized platform's turn was miscalculated and narrowed, which caused the Briz-M upper stage's disorientation and the satellite's journey to a wrong orbit," the agency said.Other systems in the upper stage performed well, the agency said, adding it has lifted a ban on launches of the Proton-M carrier rockets equipped with the Briz-M upper stage.Local media reported the Briz-M, manufactured by the Khrunichev State Research and Production Space Center, has had five failures over its 12-year history of operation.On Aug. 18, a Proton-M carrier rocket failed to deliver a communications satellite into orbit. After the failure, Russia suspended launches of Proton-M rockets pending the outcome of an investigation into the failure.

CHONGQING, May 28 (Xinhua) -- Non-infectious chronic diseases have become the major threat to human health in China as deaths from such diseases account for 85 percent of annual total deaths in the country, a report issued Saturday warned.The report said a 2008 national survey on mortality cause in China showed that the figure was up from 53 percent in 1973. Such diseases result in 3.7 million deaths annually.The Disease Prevention and Control Bureau under the Ministry of Health, and the Chinese Center for Disease Control and Prevention conducted the study, which was released at a national forum on prevention and control of chronic diseases in Chongqing.The mortality-cause survey shows that four non-infectious chronic diseases -- Cerebrovascular disease, cancer, respiratory disease and heart disease -- are the four principal causes that led to the largest number of deaths in China.Chronic diseases are the leading cause of mortality in the world, accounting for 60 percent of all deaths, reports the World Health Organization.According to the report, changes in lifestyle is one of the reasons that chronic diseases are increasing. Food with high contents of fat, protein and salt can lead to high blood pressure, high blood-fat and high blood sugar. Meanwhile, more people ride in vehicles instead of walking, meaning they exercise less.Experts at the forum called for more efforts to prevent and treat chronic diseases."It allows no delay," Kong Lingzhi, the vice director of the Disease Prevention and Control Bureau said, underlining the importance of reinforcing public education on chronic disease prevention and control."The earlier patients are aware of chronic diseases and receive proper medical treatment, the more likely they could overcome the diseases," she said.According to Kong, China has set a strategy to cope with chronic diseases in which government assumes the main responsibility, while the focus is on prevention.She said China would work to establish a prevention mechanism that pools the efforts of households, communities, professional institutions, and society at large.
