WASHINGTON, May 27 (Xinhua) -- Two U.S. astronauts conducted the fourth and final scheduled spacewalks for space shuttle Endeavour 's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) announced.The seven-hour, 24-minute spacewalk completed by Mike Fincke and Greg Chamitoff at 7:39 a.m. EDT (1139 GMT) was the final spacewalk conducted by space shuttle astronauts before NASA turns over Endeavour and sister ships Discovery and Atlantis to museums. Space station crew will continue to make spacewalks for maintenance and repair tasks.At 5:02 a.m. (0902 GMT), Fincke and Chamitoff surpassed the 1, 000th hour astronauts and cosmonauts have spent spacewalking in support of space station assembly and maintenance. The milestone occurred four hours and 47 minutes into the spacewalk, the 159th in support of station assembly and maintenance, totaling 1,002 hours, 37 minutes.The astronauts completed their mission to stow the 50-foot-long boom on the station truss and work on some new installations to extend the space station's robotic arm. After that, shuttle commander Mark Kelly called Mission Control in Houston to mark the milestone -- after 12 years of efforts."Space station assembly is complete," Kelly said.It was the 248th spacewalk U.S. astronauts have conducted and the 118th from space station airlocks. Landing is scheduled for 2: 32 a.m. EDT (0632 GMT) on Wednesday at the Kennedy Space Center in Florida. Shuttle Atlantis is targeted to launch on July 8 for space shuttle's final flight.Endeavour lifted off on May 16 from the Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion- dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).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.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.

BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

CANBERRA, March 23 (Xinhua) -- Up to 45 native species in Western Australia's Kimberley region will die out within 20 years if no action is taken, latest study showed on Wednesday.The Priority Threat Management to Protect Kimberley Wildlife report, released by Commonwealth Scientific and Industrial Research Organization (CSIRO) on Wednesday, was commissioned by the Wilderness Society.The report showed that at present, 20.2 million U.S. dollars a year is spent on conservation efforts in the Kimberley, which is home to an assortment of threatened species.However, the report said even if that money was spent properly, the region would still lose some 31 native animals.The numbers of many more birds, reptiles and mammals, such as the Spotted Tree Monitor and the Western Chestnut Mouse, would dwindle.It called for an immediate cash injection of 96 million U.S. dollars to save creatures like the Golden Bandicoot, the Scaly- Tailed Possum and the Monjon Rock Wallaby from extinction.It will follow by an ongoing investment of 40.43 million U.S. dollars annually in the Kimberley to protect its species, as well as boost plant life, help the climate and conserve indigenous land."This investment is great value," one of the report's six co- authors Hugh Possingham said in a statement released on Wednesday."We can save some of Australia's most iconic mammals and birds at a cost of only about one million U.S. dollars per species per year."

LIMA, May 5 (Xinhua) -- A total of 53.5 million people in Latin America and the Caribbean suffer from hunger or malnutrition, experts said at an international forum here Thursday.Juan Garcia, coordinator of the 5th work-group meeting of the Latin American and Caribbean Initiative Without Hunger, said the figure has not increased since 1990.Experts and officials from 13 countries gathered to discuss the challenges facing regional food security and advances that have been made, hoping to make cooperative efforts to eradicate hunger and malnutrition by the year 2025.Carcia said people affected most across the continent are still those living in rural areas as well as African descendants and indigenous people who suffer from "exclusion and inequality."The main cause of undernutrition is not lack of food-production capacity, but access to food, Carcia said.Six countries, Brazil, Ecuador, Venezuela, Guatemala, Honduras and Nicaragua, have approved food security laws with nine more in the process of doing so. The laws are considered as a way to ensure that local agricultural products are primarily used to feed the countries' own populations and not used for export.
