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.

The severe water shortages have become a major bottleneck to our sustainable development. Nearly two-thirds of the cities in China lack water," said Chen Lei, Minister of Water Resources.From 2011 to 2015, China will strive to limit its annual water consumption within 620 billion cubic meters and cut water consumption per 10,000 yuan of GDP by 30 percent.

MOSCOW, May 13 (Xinhua) -- The main and backup crews that will fly to the International Space Station in June have passed preflight tests and are ready for space travel, the Russian Cosmonauts Training Center said Friday.The main crew includes Russian cosmonaut Sergei Volkov, Japanese astronaut Satoshi Furukawa and American astronaut Michael Fossuma.A Russian spaceship Soyuz TMA-02M will send the crew to the space station on June 8, Interfax news agency reported.The backup crew includes members from Russia, the Netherlands and the United States.The crews were tested on the various emergency situations they could face during the flight.Next Monday, the commission will make a final choice of crewmembers for the launch.The crew will spend 161 days in orbit and conduct three space walks.

BEIJING, March 7 (Xinhua) -- The Chinese currency Renminbi (RMB), or the yuan, on Monday strengthened to an all-time high of 6.5651 per U.S. dollar, according to the China Foreign Exchange Trading System.Monday's central parity rate of the RMB against U.S. dollar was 20 basis points lower than the previous record of 6.5671 set on last Friday.The yuan has appreciated 3.84 percent since June 19 last year when the People's Bank of China, the central bank, announced it would further reform the exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market for each business day.
