BEIJING,Nov. 9 (Xinhuanet) – Yinghuo-1, China's first interplanetary spacecraft, is set to hitch a ride with Russia's Phobos-Grunt Mars mission in the early hours on Wednesday, after a two-year delay.A Zenit-2SB rocket will carry Yinghuo-1 and Phobos-Grunt into space from the Baikonur Cosmodrome launch site in Kazakhstan.It is China and Russia's first joint Mars operation and also marks China's first voyage to the Red Planet, China Great Wall Industry Corp said in a news release on Tuesday.Yinghuo-1 will work in orbit with Phobos-Grunt for more than 12 months in collecting data on the Martian atmosphere.Both spacecraft will travel for more than 10 months before entering Martian orbit. During the trip, Yinghuo-1's power supply, communications and temperature gauge will be controlled from the Russian craft, scientists said.Both craft will orbit the planet three times before decoupling. The 106-kg Yinghuo-1 will circle Mars in an elliptical orbit, while Phobos-Grunt will actually land on Phobos, one of the two Martian moons, and bring back soil samples to Earth."The collaboration with Russia will enhance China's ability in deep space exploration, improve spacecraft design and development, and promote planetary exploration," said an unnamed official with the corp, a subsidiary of the China Aerospace Science & Technology Corp. Russia's Lavochkin Research and Production Association signed a cooperation contract, based on an agreement between the Chinese and Russian governments, with China Great Wall Industry Corp in 2007.Yinghuo-1, with a two-year lifespan, also has its own scientific goals.These include analyzing the planet's magnetic environment and ionosphere (upper atmosphere), taking images of topographical features and studying gravity fields on the Martian equator.Pang Zhihao, deputy editor-in-chief of the monthly publication, Space International, said China's focus on the planet's upper atmosphere is significant.Twenty detectors have explored parts of Mars, but most of them have looked for traces of life or water or places suitable for setting up colonies, he said.But studying the upper atmosphere is also vital if humans are to live on the planet, he said.The mission was set for October 2009, but later postponed to this year to enhance the reliability of the project.Only the United States, the former Soviet Union and the European Union have succeeded in landing probes on Mars. Five are in operation, four belong to the US and one belongs to the EU.At least 21 probes sent to the planet have failed. The Shanghai Academy of Spaceflight Technology under the CASC, which designed Yinghuo-1 in 23 months, said that the satellite posed a major technological challenge as the furthest space destination for China before had been the moon. The moon's average distance from Earth is about 384,000 km. The distance between Mars and Earth, depending on orbits, ranges from approximately 55 million km to about 350 million km.Yinghuo-1 will have to endure periods in the freezing dark side of the planet.It underwent simulated tests that matched the Martian temperature, - 260 C.Because of the distances involved, the satellite cannot rely on ground control to adjust position. It will rely on its own onboard computer, scientists said.

BEIJING, Nov. 3 (Xinhua) -- Two Chinese spacecraft accomplished the country's first space docking procedure early Thursday, silently coupling in space more than 343 km above Earth's surface.Nearly two days after it was launched, the unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 at 1:36 a.m., marking another great leap for China's space program.The success of the docking procedure makes China the third country in the world, after the United States and Russia, to master the technique, moving the country one step closer to establishing its own space station.A video grab taken from the China Central Television on Nov.3, 2011 shows the Shenzhou-8 spacecraft docking with the Tiangong-1 space lab module. Unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 early Thursday, according to the Beijing Aerospace Control Center.President Hu Jintao, who is in France for the G-20 summit, sent a congratulatory message on the success of the country's first-ever space docking."Breakthroughs in and acquisition of space docking technologies are vital to the three-phase development strategy of our manned space program," Hu said in the message.Hu said he wishes all the program participants to try all out to fulfill a complete success of the whole mission after the smooth docking.Other leaders, including Wu Bangguo, Wen Jiabao, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, who are Standing Committee members of the Political Bureau of the Communist Party of China Central Committee, watched the mission at the Beijing Aerospace Flight Control Center.China is now equipped with the basic technology and capacity required for the construction of a space station, said Zhou Jianping, chief designer of China's manned space program."This will make it possible for China to carry out space exploration on a larger scale," he said."The capability increases China's ability to act independently in space, as well as its ability to cooperate with others," said Gregory Kulacki, senior analyst and China project manager at the global security program of the Union of Concerned Scientists, a nonprofit scientific advocacy group based in the United States."China's pursuit of an original solution to space docking, that is based on their understanding of the experience of other nations, could lead to innovations or experiences other space-faring nations could find useful," Kulacki said.The world's first space docking was achieved in 1966, when the manned U.S. spacecraft Gemini 8 docked with an unmanned Agena Target Vehicle.Forty-five years later, the maneuver remains a technological challenge. Many of mankind's 300-plus attempts have been met with difficulties or resulted in failure."To link up two vehicles traveling at 7.8 km per second in orbit, with a margin of error of no more than 20 centimeters, is like 'finding a needle in a haystack'," Zhou said.The Shenzhou-8 and Tiangong-1 will separate after flying together for 12 days. After that a second docking procedure will be conducted.Rendezvous and docking, essential to exploring space beyond Earth's orbit, create the possibility of building space stations, resupplying them, transferring astronauts and rescuing them.Without this key know-how, exploration of the moon and beyond requires carrier rockets with significant amounts of thrust. China does not currently possess rockets of this magnitude.Shenzhou-8 and Tiangong-1 both weigh about 8 metric tons, well within the delivery capacity of the Long March 2F rocket. A permanent orbiting space station is designed to be as heavy as 60 metric tons, with docking ports accommodating both manned and freight space vehicles.The interior of both the Shenzhou-8 and Tiangong-1 is an actual environment in which astronauts can live and work. After the Shenzhou-8 tests, the Tiangong-1 will remain a target orbiter for more docking procedures in 2012 by the Shenzhou-9 and -10 spacecraft, at least one of which will be manned to conduct manual docking.Although the Shenzhou-8 is unmanned, it is equipped with devices to record images and data that will help China make improvements to its spacecraft design and astronaut training.Two female astronauts are now believed to be on the active duty roster for future Shenzhou missions, said Chen Shanguang, director of the Astronaut Center of China (ACC)."We must assess both male and female astronauts to verify if human beings can live in space, as there are huge differences between men and women in spite of their common generalities," Chen said."Space exploration activities would be incomplete without the participation of female astronauts," Chen said.The Chinese spacecraft also feature collaborative space experiments under the framework of a Chinese-German science and technology cooperation.German scientists designed bio-incubators for the experiments, while their Chinese counterparts were in charge of the development of control equipment, China's manned space program spokeswoman Wu Ping said.

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.

HELSINKI, Nov. 7 (Xinhua) -- A data leak was uncovered in Finland Saturday, in which personal details of around 16,000 people were uploaded onto a file-sharing website, according to Finnish media report on Monday.This act of sabotage is the largest ever of its kind in Finland. The data leak is being looked into by the Finnish National Bureau of Investigation.Anonymous Finland claimed on Monday responsibility for the publication of personal details of thousands of Finns. The group temporarily published a sample of information on 16,000 people as proof of the hack. The hack was motivated by an apparent desire to shame the Finnish government into improving data security.Finnish National Bureau of Investigation has not confirmed the claims that a loose group of hackers known as Anonymous was behind the data leak.The list that was put on the Internet contains the names, full social security numbers, addresses, telephone numbers, street addresses, and email addresses of the victims. Several upper secondary vocational education institutions are on the list, and some civil servants and students of the Police College of Finland are mentioned by name.Finnish police have confirmed that the names of some Finnish Defense Forces staff are on the list. Finnish Defense Forces found out that fewer than 10 of its employees are included, and has informed these people. The military said the leak did not pose a security threat.

BEIJING, Jan. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.
