WASHINGTON, May 1 (Xinhua) -- The launch of U.S. space shuttle Endeavour on its final voyage will be no earlier than May 8, after technical problems uncovered last week proved more complex than originally thought, the U.S. National Aeronautics and Space Administration (NASA) announced Sunday.NASA tried to launch Endeavour on Friday on its 25th and final flight to deliver the 2-billion-dollar Alpha Magnetic Spectrometer (AMS) particle detector to the International Space Station. AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.The space shuttle Endeavour sits on launch pad 39A as work continues on the shuttle's auxilliary power unit at the Kennedy Space Center in Cape Canaveral, Florida May 1, 2011.However, the launch was called off after engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs' hydrazine from freezing on orbit.NASA hoped Endeavour would lift off on Monday. But further trouble-shooting indicated the glitch was more complicated than officials hoped initially.The failure appears to be a power problem within the aft load control assembly-2, a box of switches controlling power feeds."That basically means the power is not getting out to the heaters that weren't working on launch day," said Space Shuttle Program Launch Integration Manager Mike Moses.

SHANGHAI, Feb. 19 (Xinhua) -- Shanghai and several other Chinese cities have moved to restrict home purchases in a bid to deflate bubbles in the real estate market.The rules, which were revealed by Shanghai's Housing Guarantee and Administration Bureau on Saturday, prohibits new home purchases from locally-registered families who have owned two or more homes and non-local registered families who have owned at least one home.Additionally, non-Shanghai registered families who have no documents certifying they have paid for social security or income tax in the city for one year are banned from buying property.Sales of commercial homes fell 42.4 percent year on year in Shanghai in 2010 as earlier measures to curb the speculative demand in the real estate market took effect.Despite the fall in sales volume, the average price of new commercial homes rose by 7.6 percent to 20,995 yuan (3,200 U.S. dollars) per square meter last year.On the same day, authorities in the eastern city of Nanjing and the northeastern city of Harbin rolled out similar purchase restrictions.On Wednesday, the Beijing municipal government unveiled even tougher measures to prohibit home purchases from non-local registered families who have no proof of social security or income tax payments in the Chinese capital for five straight years.The purchase limits came after the State Council, China's Cabinet, ordered late last month that cities where home prices are skyrocketing must implement strict measures to restrict home purchases over a period of time.The State Council also said that local governments will be responsible for the stable and healthy growth of property markets and are required to publicize, before the end of March, the annual "controlled" price targets for new homes.China has implemented a series of measures since last year, which includes higher down payment and lending rates, and bans on mortgage loans for third homes, to rein in the rapid rise in housing prices.Soaring prices have become a major concern for urban Chinese residents as more homes turn unaffordable. In fact, home prices in some major cities such as Beijing have more than doubled over the past two years.

CHANGSHA, Jan. 25 (Xinhua) -- More than 8,000 fake goods were destroyed Tuesday in central China's Hunan Province, as part of Chinese efforts to protect intellectual property rights (IPR).Supervised by Changsha customs official, trucks rolled over a huge pile of counterfeit electronic devices in the city, the provincial capital.The trucks crashed imitation Nokia, Motorola and Apple laptop computers, cell phones, earphones and compact discs.Pirated books and Gucci handbags were incinerated.Changsha customs have confiscated more than 34,000 fake items worth 1.3 million yuan (197,470 U.S. dollars) over the past two years, said Liu Zili, a customs official.Some confiscated fake goods were donated to Red Cross societies and quake-devastated regions, in accordance with China's IPR protection regulations.

PARIS, May 17 (Xinhua) -- Arianespace has approved the preparation review of the third Ariane 5 flight, which is expected to lift two communication satellites on Friday from the spaceport in French Guiana, the European launching center said on Tuesday.The prior readiness review approved that "Ariane 5 is now cleared for its May 19 rollout from the Final Assembly Building to the ELA-3 launch zone, where it will be readied for liftoff on Friday at 5:38 p.m. local time in French Guiana," the space center said in a statement.This dual payload flight will orbit GSAT-8 and ST-2 satellites, with a combined mass of 8,190 kilo grams.Built by Japan's Mitsubishi Electric Company, ST-2 will be utilized by the ST-2 Satellite Ventures joint company of Singapore Telecommunications Ltd (SingTel) and Taiwan's Chunghwa Telecom Company Ltd. for Ku- and C-band relay services across the Middle East, Central Asia, India and Southeast Asia.The lighter passenger GSAT-8, built by the Indian Space Research Organization (ISRO), will serve to augment India's Ku- band relay capabilities and offer aircraft navigation assistance over Indian airspace and adjoining areas with its two-channel GAGAN system.The Arianespace started its 2011 busy year for heavy-lift Ariane 5 with the milestone launch of Europe's second Automated Transfer Vehicle (ATV) on February 16, and then a dual payload on April 22 that orbited Yahsat Y1A and Intelsat New Dawn satellites.
