MOSCOW, Aug. 3 (Xinhua) -- Two Russian cosmonauts manually launched a mini satellite from the International Space Station ( ISS) during a six-hour spacewalk Wednesday, said the Mission Control center near Moscow.Sergei Volkov and Alexander Samokutyayev, who started the spacewalk with a 20-minute delay, found the 30-kg Kedr has lost one of its two antennas during its delivery to the ISS in January. After consulting with the Mission Control, they have decided to launch the device anyway, Interfax news agency reported.The Kedr satellite, which was made by Russian students, was created to transmit from the orbit greetings in 15 languages about the 50th anniversary of Yuri Gagarin's first space flight. It could also photograph the Earth and re-transmit information from the ISS equipment.During the spacewalk, the cosmonauts were expected to install new stream video equipment on the station's outer surface, and to take pictures holding photos of the founders of Russian space explorations, including Konstantin Tsiolkovski, Sergei Korolyov and Yuri Gagarin.

BEIJING, Sept. 6 (Xinhuanet) -- The amount of space junks floating in Earth's orbit has reached a critical level, warned scientists.The future space missions may become too dangerous to fly for a risk of colliding with space junks, said a report released recently by the U.S. National Research Council (NRC).The kinds of space junks range from huge, the report said, there are thousands of discarded satellites and rocket boosters and countless tiny pieces of daily gabages from space missions.The debris are traveling in orbit at 17,500mph, at such a speed even a tiny clash can destroy a spacecraft.The NRC recommended that NASA should launch a plan to clean up the floating debris and called on other major space nations' cooperation."The current space environment is growing increasingly hazardous to spacecraft and astronauts," said Kessler, an ex-NASA researcher, "NASA needs to determine the best path forward for tackling the multifaceted problems caused by meteoroids and orbital debris that put human and robotic space operations at risk."

BEIJING, Aug. 2 (Xinhuanet) -- The first close-up pictures of the asteroid Vesta, a protoplanet that dates back to the early days of the solar system, were revealed Monday by NASA scientists.The images were taken by the U.S. space agency's Dawn robotic probe, which is two weeks into a planned year-long survey of the second largest object in the main asteroid belt, located between Mars and Jupiter.About twice the size of California, Vesta is second in size only to Ceres, Dawn's next target and, along with Pluto, one of just five known dwarf planets. NASA is spending 466 million dollars to explore Vesta and Ceres during the course of a 10-year mission.Images from Dawn show Vesta a surprisingly diverse terrain and several unexplained geologic features. Chaotic terrain near the south pole is dominated by a towering central peak and huge ripple-like grooves stretching around its equatorial belt. Bright spots, dark pits and craters are filled with unexplained streaks of black and white debris. Terrain north of the grooves is much more heavily cratered.Scientists believe Vesta grew from a clump of gas and dust left over after the sun's birth some 4.65 billion years ago, a supernova explosion, which added radioactive materials to the growing body.Dawn will spend about a year circling Vesta, tweaking its orbit and altitude using an innovative technology called ion propulsion system, chief engineer Marc Rayman with NASA's Jet Propulsion Laboratory in California said.The ion propulsion system will enable Dawn to leave Vesta's orbit after a year of study and head off to Ceres, which is the largest object in the asteroid belt.

CHENGDU, Sept. 20 (Xinhua) -- A United Nations official said Tuesday that she hopes China will take every opportunity to reinforce, support and lead the UN's agenda and "infuse it with strength and wisdom.""The more China gives, the better the UN can become," said Renata Lok-Dessallien, UN Resident Coordinator and United Nations Development Program (UNDP) Resident Representative in China, at the Seminar in Memory of the 40th Anniversary of the Resumption of Lawful Rights of China in the United Nations.The three-day seminar from Sept. 19 to 21 is being held in the city of Chengdu in southwest China's Sichuan Province. About 100 UN and Chinese officials are gathering to discuss China's role in the UN, as well as the UN's role in global diplomacy.Lok-Dessallien said that the General Assembly Resolution of Oct. 25, 1971 was an "important milestone in China's international relations and in the history of the United Nations.""It restored the rights of the People's Republic of China in the United Nations and marked China's entry to the world stage," she said.Steven Sabey, a senior policy advisor from the UNDP's China office, said that China plays an important role in facilitating cooperation about the member states of the United Nations."China needs the United Nations, and the United Nations also needs China," said Wu Hailong, China's assistant minister of foreign affairs."We must recognize that as the largest developing country in the world, China needs to manage its domestic affairs first, as this can have a positive effect on humanity as a whole," Wu said.As China's role in the world continues to grow and evolve, the UN's role in China will also grow, according to Lok-Dessallien."As China's development trajectory continues to evolve, we are entering significantly new territory in the UN-China relationship," she said.Sabey said that he hopes China will strengthen its cooperation with the United Nations in order to further improve intercultural communication and allow China to contribute more to other developing countries."The United Nations is committed to continuing to deepen and strengthen our partnership as we tackle the many global challenges ahead," said Lok-Dessallien.

SAN FRANCISCO, Aug. 10 (Xinhua) -- Amazon on Wednesday launched Kindle Cloud Reader, a web-based app that may help the on-line retailer to sidestep Apple's App Store restrictions.In its announcement, Amazon said Kindle Could Reader uses the HTML5 web standard to let users read e-books from their Kindle library from the Safari browser or Google's Chrome browser on their desktops or tablet, including the iPad.Support for Internet Explorer, Firefox and the Blackberry Playbook will be launched later this year.The app has a button linked to the Kindle Store, which was removed recently from the Kindle apps for iPad and iPhone.The move is taken as an answer to Apple's latest App Store restrictions, which banned developers to have any external links for purchasing digital books or subscriptions in the app, unless they give Apple a 30 percent cut from the in-app sales.Besides Amazon, Barnes & Noble, Google Books and Canadian e- book seller Kobo have also altered their iPad and iPhone apps to comply with the rules.Meanwhile, publishers and retailers have been developing web- based HTML5 apps to sidestep Apple for more control, which is an approved-of technology for iOS devices.The Financial Times, Kobo and video-on-demand service Vudu have recently launched their HTML5 app to avoid paying Apple a 30 percent cut.Industry watchers said it is unknown how Apple will deal with such apps. It would be easy for Apple to disable Web apps in the iPad's Safari browser, but the company would certainly face some backlash, said tech media website CNET.
