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. 23 (Xinhua) -- An online survey has revealed that Chinese people have a mixed opinion on Sunday's Spring Festival TV gala, the 30th of its kind since 1983, albeit many of them agree that there were innovations and improvements in it.As of 10:00 p.m. Monday, about 48 percent of some 71,000 respondents in the poll held by sina.com.cn, one of China's major portal websites, said they think the gala fall short of their expectations.Another 23 percent of them said they think the gala was just fine, and only 10 percent said it was splendid.The gala, an annual grand celebration broadcast by the China Central Television on the eve of the traditional Spring Festival, China's lunar New Year, is the most-watched TV event in the country."I can see the efforts of the gala staff, but it is still not good enough," said netizen "roam the life" at the Sina weibo, a popular Twitter-like microblogging website.At the Sina weibo website, the topic "grumble at the 2012 Spring Festival TV gala" has outnumbered others with over 64 million comments and become the hottest topic of Monday.Nonetheless, many people acknowledge the innovations and improvements in the gala.The gala made some attempts to take a more public-friendly approach by inviting some "grassroots" performers, such as farmer-singer Zhu Zhiwen, as well as cutting all commercials during the broadcast.A dance performance depicting a romance of peacocks and starring Yang Liping, a well-known dancer in China, is the most-followed topic at the gala's official weibo account, drawing over 3,500 comments.The audience was also impressed by a piano duet played by Li Yundi, first prize winner of the the 14th Frederic Chopin international piano competition, and Leehom Wang, a Chinese-American pop singer-songwriter.Moreover, about 59 percent of the online poll respondents said the stage design was quite cool."There are really many improvements in the gala, but it is absolutely difficult to please everyone," wrote weibo user "Wawamiaowaiwai."Unlike their elder generation, the young generation in China has more diversified options for entertainment, and it is of great challenge to attract them at the Spring Festival celebration, said Xia Xueluan, a professor of sociology with Peking University.

WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."

SAN FRANCISCO, Dec. 9 (Xinhua) -- Hewlett-Packard (HP) on Friday announced that it is keeping the webOS software alive by contributing it to the open source community.The company said it will make the underlying code of webOS available under an open source license and will engage the open source community to help define the charter of the open source project."WebOS is the only platform designed from the ground up to be mobile, cloud-connected and scalable," Meg Whitman, HP's chief executive officer, said in a statement."By contributing this innovation, HP unleashes the creativity of the open source community to advance a new generation of applications and devices," she added.HP said it will remain active in the development and support of webOS, while the source code will be available for use and improvement by anyone choosing to download it, which means other hardware manufacturers can also use the software.With the help of the open source community, HP can save development and other costs and the new announcement is expected to result in more layoffs from its webOS team, some analysts noted.The webOS is a mobile operating system initially developed by Palm which was acquired by HP last April for 1.2 billion U.S. dollars.In February this year, HP released TouchPad, its first tablet computer which runs the webOS operating system. The device didn't sell well, and HP in August decided to completely shut down webOS hardware business, including TouchPad and webOS phones.HP then said that it will continue to explore options to optimize the value of webOS software going forward.By keeping the software open source, users of webOS devices will continue to receive software improvements and updates in the future, HP noted."As webOS gains traction as an open source alternative in the marketplace, you could see webOS on several different types of devices by any number of vendors. We will explore the viability of putting webOS on devices, just as we do for other leading operating systems," the company said in a corporate blog post.

KUNMING, Nov. 30 (Xinhua) -- More than 10,000 new HIV infections were reported in southwest China's Yunnan province during the first 10 months of this year, bringing the total number of HIV carriers and AIDS patients in the province to more than 90,000, local AIDS prevention authorities said Wednesday.As of Oct. 31, a total of 93,567 HIV infections had been reported in the province, with the disease claiming 14,340 lives, according to statistics from the Yunnan AIDS Prevention Bureau.The number of HIV infections contracted through sexual contact has been rising and sexual contact is now the main cause of the disease's proliferation, said Xu Heping, director of the bureau.Of the province's infected population, 45.8 percent contracted the disease through sexual contact, while 37.3 percent contracted the disease through intravenous drug abuse, according to the bureau.Sexually transmitted infections accounted for 77.3 percent of new infections during the January-October period, up from 71.3 percent during the same period last year, according to the statistics.Xu said this year's new infections mainly occurred in people between the ages of 20 and 39, accounting for 60.8 percent of the total.Infections among rural residents and unemployed people accounted for 55.3 percent and 18.6 percent, respectively, of this year's total, according to Xu.Lu Lin, director of the Yunnan disease control and prevention center, said migrant workers are particularly vulnerable to the disease due to their nomadic nature and lack of knowledge about the disease.China currently has 346,000 registered HIV carriers and AIDS patients, although the actual number is predicted to hit 780,000 by the end of this year, according to an expert panel consisting of members of China's Ministry of Health (MOH), the World Health Organization and UNAIDS.
