BEIJING, Feb. 1 (Xinhua) -- A ceremony with a bonfire and firecrackers was held Tuesday night in the new seat of a quake-leveled county in southwest China's Sichuan Province, prior to the Chinese Lunar New Year on Thursday.The Lunar New Year, or Spring Festival, is the most important Chinese holiday. It is a time for family reunions, gift giving and fireworks.It will be even merrier for the survivors of the Wenchuan earthquake in 2008, who just moved into their new homes in the new town.The earthquake survivors are preparing for the first Spring Festival in their new homes.Xia Tianfeng of Beichuan County, Mianyang City, is sticking red paper decorations onto the windows of her new house for good luck in the New Year."We finally have our new house. Why wouldn't I be happy?" asked Xia.She and her family lived in a makeshift house for two years before moving into their new house one month ago.Dong Depa, 43, and his family moved into their new house in Yingxiu Town, the epicenter of the quake, five days ago."I can pay off the debt incurred to build the house in two years," said Dong, who spent only 30,000 yuan (4,541 U.S. dollars) for the house's construction and decoration, with the rest being shouldered by the government.Dong lost his two children in the quake but he and his wife have since had another child, a son."Last year, we spent the Spring Festival in the dormitory of the brick factory where I work as a cook. Now we can finally enjoy the festival in our own home," said Dong, unable to conceal his joy.Xia told Xinhua the ceremony for the new county seat was the real taste for a happy new year.Reconstruction has finished in the quake-hit zones in Sichuan, with most survivors now in their new houses.In Beichuan County alone, 96.5 percent of the survivors already have their new house.The new county seat is located in Yongchang Town, about 23 kilometers from the quake-leveled old one.The 8.0-magnitude earthquake struck southwest China on May 12, 2008, leaving about 80,000 people dead or missing.Waving goodbye to their temporary barracks, 7,397 households have been allocated new apartments, among which 3,504 households were former Beichuan residents, while others were from different Wenchuan earthquake-hits regions."The new apartment has already been simply decorated by the time I received the door key. With our new furniture, we can wait no longer to move into the home," said 45-year-old Xie Xinghe, a former resident of Beichuan.Including 50,000 yuan (about 7,575 U.S. dollars) in loans, Xie paid a preferential price of 79,600 yuan (about 12,000 U.S dollars) for the 100 square meter new apartment.Losing his only son in the earthquake, Xie and his wife adopted a one-year-old boy."It is the child who brings me new hope for the future," Xie said. Following the Lunar New Year celebration in his new home, Xie will try his best to work for some years to pay back the loan and save money to ensure a better education for his son."It is such magic to build a new town within three years, even so anywhere around the world. And we see it now," said Xu Zhenxi, director with the headquarter of new town program of Beichuan, which is supported by east China's Shandong Province.From May 25, 2009 to September 25, 2010, Shandong Province supported the new Beichuan county seat project, which was completed within 15 months.

BEIJING, March 22 (Xinhuanet) -- NASA scientists are testing its next-generation Mars rover, which will land on Mars next year, under extreme conditions at space-simulation chamber in California, media reports said Tuesday.Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., say they've installed the Curiosity rover in a space-simulation chamber that can mimic the environment the probe will encounter on Mars.  After the chamber's large door was sealed last week, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius, and a bank of powerful lamps simulated the intensity of sunshine on Mars.After the test period, the rover along with other portions of NASA's Mars Science Laboratory spacecraft including the cruise stage, descent stage and backshell -- part of protective covering -- will be shipped to the Kennedy Space Center for final preparation for the launch window from Nov. 25 to Dec. 18, 2011. Curiosity will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.

CHICAGO, Jan. 21 (Xinhua) -- Chinese President Hu Jintao left Chicago for home on Friday after concluding a four-day state visit to the United States, during which Hu and his U.S. counterpart Barack Obama agreed to build a China-U.S. cooperative partnership based on mutual respect and mutual benefit.President Hu, who began his visit on Tuesday, had extensive and in-depth discussions with Obama at the White House on Wednesday on major bilateral, regional and world issues.The two sides reached "important agreement on China-U.S. relations and major international and regional issues of shared interest," the Chinese president said when he and Obama met the press following their discussions."We both agree to further push forward the positive, cooperative and comprehensive China-U.S. relationship," Hu said, adding that both sides also pledged to forge "a China-U.S. cooperative partnership based on mutual respect and mutual benefit" for the benefit of the two countries and beyond.The Chinese president said he and Obama also discussed some disagreements in the economic and trade area, with both sides pledging "to continue to appropriately resolve these according to the principle of mutual respect and consultation on an equal footing."Also on Wednesday, Hu attended a state dinner and a welcome ceremony hosted by Obama.Hu told the Americans on several occasions in Washington that the purpose of his visit to the United States was "to increase mutual trust, enhance friendship, deepen cooperation and advance the positive, cooperative and comprehensive China-U.S. relationship for the 21st century."During Hu's visit, the two countries issued the "China-U.S. Joint Statement," which says "China and the United States committed to work together to build a cooperative partnership based on mutual respect and mutual benefit in order to promote the common interests of both countries and to address the 21st century's opportunities and challenges.""China and the United States are actively cooperating on a wide range of security, economic, social, energy, and environmental issues which require deeper bilateral engagement and coordination," the statement said.On Thursday, Hu called upon the U.S. Congress to continue helping the two countries boost their relations.Pursuing a healthy and steady development of China-U.S. ties is China's established policy and strategic choice, Hu stressed when meeting House Speaker John Boehner and Senate Majority Leader Harry Reid.Also on Thursday in Washington, Hu delivered an important speech at the welcome luncheon hosted by friendly organizations in the United States.To advance the sustained, sound and steady development of China-U.S. relations serves the fundamental interests of peoples of China and the United States, he said.

BEIJING, Feb. 1 (Xinhua) -- A plane carrying Chinese nationals who were stranded in Egypt arrived at Beijing Capital International Airport Tuesday afternoon.The plane, operated by the Air China International Corporation, arrived in Beijing at 16:50 p.m. Bejing time. The second plane, operated by Hainan Airlines, will arrive in south China's Guangzhou city later Tuesday.The two planes carry a total of 480 Chinese nationals."China has attached great importance to safety of the stranded Chinese nationals since demonstrations and protests broke out in Egypt on Jan. 28," said Chinese Foreign Ministry spokesman Hong Lei at a regular news briefing.Hong said China has taken a package of emergency measures including warning against travel and an around-the-clock hotline to provide consular protection and assistance for the Chinese nationals.The spokesman said that a working taskforce, composed of officials from China's Foreign Ministry, National Tourism Administration, Ministry of Public Security and Civil Aviation Administration, are currently working with the Chinese embassy in Cairo to provide assistance to stranded Chinese in Egypt and to try to facilitate their early return to China.

You can think of NASA's Discovery program as a sort of outer-space American Idol: every few years the agency invites scientists to propose unmanned planetary missions. The projects have to address some sort of fundamental science question, and (this is the tough part) they have to be relatively cheap to pull off — say, half a billion dollars or so. Then the proposals go through a grueling competition before judges who aren't as nasty as Simon Cowell but who are every bit as tough. The one left standing at the end gets the equivalent of a recording contract: NASA supplies the funding and the launch vehicle, and away the winner goes — to orbit Mercury, as the Messenger spacecraft is doing right now; or to rendezvous with a couple of asteroids, as the Dawn mission will start doing this July; or to smash into a comet on purpose, a feat achieved by Deep Impact in 2005, a mission not to be confused with the movie of the same name. Now it's time for the next contenders. NASA has just announced that the first round of the latest Discovery competition is over, with three entries out of 28 moving on to the finals. They are, in increasing distance from Earth: the Geophysical Monitoring Station (GEMS) lander, which would use seismometers to study the interior of Mars; the Comet Hopper, which would do just that, leaping from place to place across the surface of Comet 46P/Wirtanen to see how different parts of the tumbling body react to heating by the sun; and the Titan Mare Explorer (TiME), which would plop into a sea of liquid hydrocarbons on Saturn's moon Titan — the first oceangoing vessel ever to set sail on another world. If you had to come up with a theme that ties all three missions together, it would be "origins." The Titan explorer, for example, will be studying a place that — in a crude way, at least — resembles the early planet Earth at a time when life arose here. Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules. The oceans provide a medium in which the molecules can move around and interact with each other. It's even conceivable, though clearly a long shot, that some form of microscopic life already exists on this frigid moon. The Mars lander, by contrast, would visit a place where the seas — plain water in this case — vanished long ago. But the mission of GEMS goes far deeper than that. By analyzing Marsquakes on the Red Planet, GEMS will try to get a handle on what the interior of Mars is like. Scientists don't currently know whether the planet's core is liquid, like Earth's, or solid, or some mushy consistency in between. It all depends on how efficiently Mars has cooled since it formed 4.5 billion years ago, and that depends in turn on the planet's internal structure. "That's the mission," says Bruce Banerdt, of NASA's Jet Propulsion Laboratory, the lead scientist for GEMS. "We want to understand how Mars was built." Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth. "That will let us extrapolate all the way down to the center," Banerdt says, "which will tell us how fast Mars is cooling."
