BEIJING, July 3 (Xinhuanet) -- The Atlantis mission to be launched by NASA on July 8 will not be an end to the space age, as some media suggest.Although it is the final mission of the space shuttle, it will open up "the next chapter" in the United States' space exploration, NASA's administrator Charles Bolden Jr said at the National Press Club in Washington on Friday."When I hear people say - or listen to media reports - that the final shuttle flight marks the end of US human space flight, I have to say . . . these folks must be living on another planet," he said."As a former astronaut and the current NASA administrator, I'm here to tell you that American leadership in space will continue for at least the next half-century because we have laid the foundation for success - and for NASA, failure is not an option," he said.NASA administrator Charles Bolden Jr drew a lot of media attention during his speech at the National Press Club in Washington DC.One of the foundations is the "unprecedented" research capabilities the International Space Station (ISS) now possesses, largely thanks to the space shuttle missions.Although some media imply that "the game will be up" once the ISS is out of orbit in 2020, he said the splendid research results and rich knowledge astronauts and scientists have accumulated through more than 1,200 experiments since 1998 have laid out "a stepping-stone to the rest of the solar system and the tip of what comes next".As NASA turns a new page, it will "focus on deep space exploration", while leaving US private companies to operate low Earth orbit transportation systems for tourism and business, he said.NASA will develop "a deep space crew vehicle and an evolvable heavy-lift rocket," he said. The moon, asteroids and Mars will be the next destinations for humans to live and work, he said."We will maintain and grow US leadership in space and derive all the benefits that flow from it. Tomorrow's space program is taking shape right now," he said.

BEIJING, Sept. 1 (Xinhua) -- Chinese scientists have decided to reschedule the launch of the Tiangong-1, an unmanned space module, due to the failed launch of an experimental orbiter, a spokesperson with the project said Thursday.The decision to delay the launch was based on the consideration that the carrier rocket Long-March II-F, which would be used for the upcoming launch, belongs to the same series as the malfunctioning one that led to the experimental orbiter SJ-11-04 failing to enter Earth's orbit in August."As the investigation into the malfunction of the rocket Long-March II-C remains underway, it is not clear yet whether the malfunction is linked with the Long-March II-F," the unnamed spokesperson said.Previously, the Long-March II-F was expected to send the 8.5-metric ton Tiangong-1, or "Heavenly Palace 1," into space in the second half of this year to perform the nation's first space-docking procedure.The Tiangong-1 will dock with the unmanned Shenzhou-8 spacecraft, which will be sent into space after the Tiangong-1's launch."The specific launch date for the Tiangong-1 will be set based on the results of the investigation into the malfunctioning rocket," the spokesperson said, adding that the project's teams are currently double-checking every product that will be involved in the space-docking.The Shenzhou-8 spacecraft, the Long March II-F carrier rocket, and the Tiangong-1 have all been transferred to the Jiuquan Satellite Launch Center in northwest China's Gansu Province, the spokesperson said.

WASHINGTON, Aug. 2 (Xinhua) -- Breastfeeding protects against childhood obesity, but less than 4 percent of U.S. hospitals provide the full range of support mothers need for breastfeeding, according to a report issued by the Centers for Disease Control and Prevention Tuesday.Improving rates of breastfeeding by providing better hospital support to mothers and babies is an important strategy to improve children's health, including a reduced risk of childhood obesity, the monthly Vital Signs report said."Hospitals play a vital role in supporting a mother to be able to breastfeed," it said."Those first few hours and days that a mom and her baby spend learning to breastfeed are critical. Hospitals need to better support breastfeeding, as this is one of the most important things a mother can do for her newborn. Breastfeeding helps babies grow up healthy and reduces health care costs," it added.The report found only 14 percent of hospitals have a written and model breastfeeding policy.It also found in nearly 80 percent of hospitals, healthy breastfeeding infants are given formula when it is not medically necessary, a practice that makes it much harder for mothers and babies to learn how to breastfeed and continue breastfeeding at home.Additionally, only one-third of hospitals practise rooming in, which helps mothers and babies learn to breastfeed by allowing frequent chances to breastfeed.Finally, the report found in nearly 75 percent of hospitals, mothers and babies don't get the support they need when they leave hospitals, including a follow-up visit, a phone call from hospital staff and referrals to lactation consultants, and other important support systems in their communities.

BEIJING, Sep. 1 (Xinhuanet) -- A campaign is being launched across U.S. to help lovers of sugar drinks reduce their habit by the Center for Science in the Public Interest.This campaign is based on the findings of a new survey conducted by CDC (Centers for Disease Control)."Men drink more than women, and teens and young adults drink the most," said Cynthia L. Ogden who is an epidemiologist at the CDC's National Center for Health Statistics.The campaign is called "Life's Sweeter with Fewer Sugary Drinks." And it aims to decrease intake of soda and sugary drinks down to the American Heart Association recommendation of fewer than three cans per person per week.Sugary drink intake in the U.S. has increased over the last 30 years, which has been linked with weight gain, obesity, poor diet, and type 2 diabetes.So far, the cities signing on include Boston, Chicago and Los Angeles.

HONG KONG, Sept. 9 (Xinhua) -- The Hong Kong Polytechnic University (PolyU) announced Friday that its surveying experts had successfully developed methodologies for precise mapping of the Moon, after intensive analysis of the data captured by the Chinese lunar orbiter ChangE-1 and other lunar exploration missions.According to the PolyU, the team has made significant contributions to lunar mapping. Their efforts culminated in the development of a unique and innovative approach to the creation of accurate 3D models of the lunar surface.The team has produced the most updated parameters of the lunar figure (the shape of the moon), which is essential for lunar mapping using 17.5 million laser altimetry measurements from the ChangE-1and the Japanese SELENE missions.In addition, they also used the new topographic and gravity models to calculate improved crustal thickness and mass distribution of the Moon and established that the average thickness of the Moon's crust is about 40 km on the near side and 50 km on the far side.It was introduced that the resulting lunar mapping was the hard work of a dedicated research team led by Professor Chen Yong-qi, Emeritus Professor of the Department of Land Surveying and Geo-Informatics, who is also serving on the Expert Committee of China's Lunar Exploration Programme (ECCLEP), with the concerted efforts of team members Prof. Chen Wu, Prof. Ding Xiao-li, Prof. Baki Iz, Dr. Bruce King, and Dr. Wu Bo.According to Chen Yong-qi, the lunar mapping project started in 2006. The primary objective was to develop the methodologies and techniques for mapping the Moon surface, which is much more challenging than mapping the Earth's surface because of very few surveyed control points which are essential for accurate map making.Statistics showed that there were only fourteen lunar laser ranging retro reflectors (LRRR) and Apollo lunar surface experiment package (ALSEP) transmitter sites with accurately known coordinates available only on the near side of the Moon, installed by the U.S. Apollo and former Soviet Union Luna missions in the 1960s.Moreover, according to the team, the gravitational field of the Moon is not as well-known as that of Earth, which means the accuracy of the computed lunar satellite's position at any given time is lower than for Earth satellites, thus degrading the mapping accuracy and reliability.In addition, the team expressed that highly reflective lunar surface created significant problems for the automatic processing of images to develop 3D models using the technique of photogramemtry, which is a widely used and highly reliable technique for the creation of maps and 3D models on Earth.Furthermore, the team also revealed they had a plan to compare such data with other data sources in order to evaluate the performance of the ChangE mapping sensors. Since Chen Yong-qi is serving on the ECCLEP, the team has direct access to more recent data captured by the ChangE satellite.
