WASHINGTON, March 25 (Xinhua) -- NASA's Stardust spacecraft depleted fuel and ceased operation on Thursday after a 12-year run, the U.S. space agency said Friday."This is the end of the spacecraft's operations, but really just the beginnings of what this spacecraft's accomplishments will give to planetary science," said Lindley Johnson, Stardust-NExT and Discovery program executive at NASA headquarters in Washington."The treasure-trove of science data and engineering information collected and returned by Stardust is invaluable for planning future deep space planetary missions."Artist's concept of Stardust spacecraft nearing EarthLaunched on Feb. 7, 1999, Stardust flew past the asteroid named Annefrank and traveled halfway to Jupiter to collect the particle samples from the comet Wild 2. The spacecraft returned to Earth's vicinity to drop off a sample return capsule eagerly awaited by comet scientists.NASA re-tasked the spacecraft as Stardust-NExT to perform a bonus mission and fly past comet Tempel 1, which was struck by the Deep Impact mission in 2005. The mission collected images and other scientific data to compare with images of that comet collected by the Deep Impact.The Stardust-NExT met all mission goals, and the spacecraft was extremely successful during both missions. From launch until final rocket engine burn, it travelled approximately 3.54 billion miles.After the mileage logged in space, the Stardust team knew the end was near for the spacecraft. With its fuel tank empty and final radio transmission concluded, the most traveled comet hunter will move from NASA's active mission roster to retired."This kind of feels like the end of one of those old western movies where you watch the hero ride his horse toward the distant setting sun -- and then the credits begin to roll," said Stardust-NExT project manager Tim Larson from NASA's Jet Propulsion Laboratory in Pasadena, California. "Only there's no setting sun in space."

BEIJING, March 24 (Xinhuanet) -- A new study has found that many overweight women and children often underestimate how heavy they are, according to media reports Wednesday.The study, conducted by researchers from Columbia University Medical Center in New York City, surveyed 111 women with the average age of 39 and 111 children aged between 7 and 13.Among the participants, about 66 percent of the women and 39 percent of the kids were overweight or obese.They were shown images of different body silhouettes representing a range of weights, including underweight, normal weight, overweight, obese and extremely obese.The research findings showed that 82 percent of obese women and 43 percent of overweight women underestimated their weight, while only 13 percent of normal weight women did so.As to the children group, about 86 percent overweight or obese kids low-balled their weight.Lead author Dr. Nicole Dumas said, "The implications of this is the overwhelming impact of obesity on children who are growing up in communities where obesity and overweight is the norm rather than the exception."  She added, "Strategies to overcome the obesity epidemic will need to address this barrier to weight loss."

BAODING, Feb. 2, (Xinhua) -- All-out efforts should be made to combat drought for a summer grain harvest, said Chinese President Hu Jintao Wednesday in an inspection tour to north China's Hebei Province."We need to adopt comprehensive measures to ensure supply of capital, technologies, facilities and materials to enable winter wheat to safely grow through the winter," said Hu, when inspecting drought conditions at a wheat field in Xishanbei Township of Baoding City, Hebei.Over the past three months, North China has been hit by severe drought, seriously threatening normal agricultural production.Hu, who is also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the inspection visit in Baoding from Tuesday to Wednesday, to welcome the Spring Festival, or China's Lunar New Year, with local officials and residents.Hu beat a drum together with villagers during a new year celebration in Shijiatong Village, Xishanbei Township of Baoding.The president visited the home of Yan Deshu, an aged CPC member in the village, and pasted the Chinese character "Fu", meaning fortune and happiness, on the gate of Yan's yard.Hu also visited a long-distance coach station in Baoding, and extended Spring Festival greetings to passengers, station workers and volunteers.Hu inspected a unit of armed police in Baoding and made Chinese dumplings together with the officers and soldiers.

LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.
