WASHINGTON, May 11 (Xinhua) -- NASA's Dawn spacecraft has obtained its first image of the giant asteroid Vesta, which will help fine-tune navigation during its approach, the U.S. space agency announced Wednesday.Dawn expects to achieve orbit around Vesta on July 16, when the asteroid is about 117 million miles from Earth.The image from Dawn's framing cameras was taken on May 3 when the spacecraft began its approach and was approximately 752,000 miles (1.21 million km) from Vesta. The asteroid appears as a small, bright pearl against a background of stars. Vesta also is known as a protoplanet, because it is a large body that almost formed into a planet."After plying the seas of space for more than a billion miles, the Dawn team finally spotted its target," said Carol Raymond, Dawn's deputy principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "This first image hints of detailed portraits to come from Dawn's upcoming visit."Vesta is 330 miles (530 km) in diameter and the second most massive object in the asteroid belt. Ground- and space-based telescopes obtained images of the bright orb for about two centuries, but with little surface detail.Mission managers expect Vesta's gravity to capture Dawn in orbit on July 16. To enter orbit, Dawn must match the asteroid's path around the sun, which requires very precise knowledge of the body's location and speed. By analyzing where Vesta appears relative to stars in framing camera images, navigators will pin down its location and enable engineers to refine the spacecraft's trajectory.Dawn will start collecting science data in early August at an altitude of approximately 1,700 miles (2,700 km) above the asteroid's surface. As the spacecraft gets closer, it will snap multi-angle images allowing scientists to produce topographic maps. Dawn will later orbit at approximately 120 miles (200 km) to perform other measurements and obtain closer shots of parts of the surface. Dawn will remain in orbit around Vesta for one year. After another long cruise phase, Dawn will arrive in 2015 at its second destination, Ceres, an even more massive body in the asteroid belt.Gathering information about these two icons of the asteroid belt will help scientists unlock the secrets of our solar system's early history. The mission will compare and contrast the two giant asteroids shaped by different forces. Dawn's science instruments will measure surface composition, topography and texture. Dawn also will measure the tug of gravity from Vesta and Ceres to learn more about their internal structures. The spacecraft's full odyssey will take it on a 3-billion-mile (5-billion-km) journey, which began with its launch in September 2007.

WASHINGTON, May 27 (Xinhua) -- The U.S. Treasury Department said in a report released on Friday that China was not manipulating its currency."In China, since the authorities decided in June 2010 to allow the exchange rate to appreciate in response to market forces, the renminbi (RMB) has appreciated by a total of 5.1 percent against the dollar in nominal terms through the end of April 2011, or at an annual pace of approximately 6.0 percent," noted the semi- annual report on international economic and exchange rate policies.The Treasury said that as inflation in China is significantly higher than it is in the United States, the renminbi has appreciated more rapidly against the dollar on a real, inflation- adjusted basis, at a rate of around 9 percent per year.The delayed report, which was originally scheduled to be sent to the Congress on April 15, finds "no major trading partner of the United States" manipulated its currency during the period covered in the report.The Treasury added that it will continue to "closely monitor" the renminbi appreciation pace.The report also noted that the U.S. economy is recovering from its deepest recession in the post-war period."While recent growth is encouraging, the economy still faces significant challenges," said the report. The number one challenge is still in the labor market.The U.S. unemployment rate, currently at 9.0 percent, is not expected to fall significantly this year.Besides, housing market and long-term fiscal position are " unsustainable," according to the report.In recent remarks, Treasury Secretary Timothy Geithner stated that China is the fastest growing market for U.S. exports. In 2010, U.S. exports to China grew at a pace that was 50 percent higher than the rest of the world.

BEIJING, Feb. 14 (Xinhua) -- Chinese President Hu Jintao met with delegates from the national Party building society here Monday.Vice president Xi Jinping and He Guoqiang, secretary of the Central Commission for Discipline Inspection (CCDI) of the Communist Party of China (CPC), were also present at the occasion in the Great Hall of the People.The delegates were here to attend the fifth national congress of the national Party building society which was established in 1992.Addressing the meeting Monday, Li Yuanchao, head of the Organization Department of the CPC Central Committee, called on all the party building research staff to keep focusing on their study and be innovative in thinking about party building theory so as to strengthen party building in a more scientific way.The society revised its constitution and re-elected members of its council at Monday's meeting.

BEIJING, Jan. 26 (Xinhua) -- The Chinese government Wednesday raised the minimum down payment requirement for the purchase of second home to 60 percent of the property's value from 50 percent, to curb property market speculation.The decision was announced in a statement released after an executive meeting of the State Council, China's cabinet, which was presided over by Premier Wen Jiabao.File photo taken on Nov. 14, 2010 shows a newly built residential community in east China's Shanghai Municipality.

BEIJING, Feb. 1 (Xinhua) -- Wu Bangguo, chairman of the Standing Committee of the National People's Congress of China, on Monday sent congratulatory messages to Myanmar's newly-elected upper house speaker U Khin Aung Myint and lower house speaker Thura U Shwe Mann, respectively,on their taking offices.Myanmar's house of nationalities (upper house) session on Monday elected U Khin Aung Myint, Minister of Culture, as speaker of the upper house.Also on Monday, No. 3 Myanmar state leader Thura U Shwe Mann, who is a member of the State Peace and Development Council and previously the Chief of General Staff of the army, the navy and the air force, was elected as speaker of the house of representatives by the house of representatives (lower house).
