WASHINGTON, Nov. 8 (Xinhua) -- NASA plans to add an unmanned flight test of the Orion spacecraft in early 2014 to its contract with Lockheed Martin Space Systems for the multipurpose crew vehicle's design, development, test and evaluation, the U.S. space agency announced Tuesday.This test supports the new Space Launch System (SLS) that will take astronauts farther into space than ever before, and provide the cornerstone for America's future human spaceflight efforts."President Obama and Congress have laid out an ambitious space exploration plan, and NASA is moving out quickly to implement it," NASA Associate Administrator for Communications David Weaver said in a statement. "This flight test will provide invaluable data to support the deep space exploration missions this nation is embarking upon."Orion is part of the now defunct Constellation program canceled under President Barack Obama's 2011 budget proposal. Instead Obama urged NASA to work toward sending humans to an asteroid and then on to Mars -- and NASA says it wants to go ahead with that as quickly as possible.This Exploration Flight Test, or EFT-1, will fly two orbits to a high-apogee, with a high-energy re-entry through Earth's atmosphere. Orion will make a water landing and be recovered using operations planned for future human exploration missions. The test mission will be launched from Cape Canaveral to acquire critical re-entry flight performance data and demonstrate early integration capabilities that benefit the Orion, SLS."The entry part of the test will produce data needed to develop a spacecraft capable of surviving speeds greater than 20,000 mph and safely return astronauts from beyond Earth orbit," Associate Administrator for Human Exploration and Operations William Gerstenmaier said. "This test is very important to the detailed design process in terms of the data we expect to receive."

PARIS, Dec. 23 (Xinhua) -- French health authorities on Friday urged 30,000 women to remove the local-made breast implant, pledging that relevant expenses would be covered by the state.The health ministry said in a statement that they spot "no increased risk of cancer currently in women wearing the PIP (Poly Implant Prothese) brand compared with other implants.""However, well-established risks associated with these prostheses are rupture and irritant gel may lead to inflammatory reactions, making it difficult to explant," the statement added.French Health Minister Xavier Bertrand advised French women who have the PIP implants to get them taken out "as a preventive measure but not of an urgent nature." The removal of the implant will be at the state's expense.The recommendation came after eight cases, mainly breast cancer, were reported recently among women with PIP implants.The involved implant was produced by the French company PIP, once the world's third-largest producer of silicone implants who sold its products to tens of thousands of women in more than 65 countries, mainly in South America and western Europe.

WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

BEIJING, Oct. 12 (Xinhuanet) -- Study found that women who took multivitamins may actually be at risk, media reports on Wednsday.Women who took the dietary supplements vitamin B6, folic acid, magnesium, zinc, copper, iron and multivitamins had a higher risk of death than women who did not.The new study, published in the Archives of Internal Medicine, examined more than 38,000 women aged 55 and older who took part in the Iowa Women's Health Study, which started in the mid 1980s. Researchers found the vitamins did nothing to reduce the risk of death and that most supplements have no positive effect on women's health.The study did not distinguish if the women in the study took the vitamins to fight diseases or to maintain health.Vitamin experts say the best way to make sure you are getting all necessary vitamins is to eat a well-balanced diet. The vitamins people take do not  depend on personal preference.

BEIJING, Dec. 7 (Xinhua) -- China backs European efforts for further integration and supports current initiatives by the European Union to tackle the debt crisis, Chinese Foreign Ministry spokesman Hong Lei said Wednesday.Hong told a regular press briefing that China will work with the international community to help stabilize the global financial market and promote the recovery and growth of the world economy."We have noted that the EU has made a series of important proposals to address the European sovereign debt crisis and we hope such proposals can work to help stabilize the market, restore market faith and prevent the crisis from deteriorating," Hong added.Europe's powerhouses France and Germany agreed Monday on a series of reforms aimed at changing the European Union treaty to impose tough controls on eurozone budgets.The new treaty would include automatic sanctions for states that fail to observe the 3 percent deficit rule, as well as a budget-balancing rule across the eurozone.New and significant decisions to tackle the crisis might be made during the EU summit to be held from Dec. 8 to 9, Hong predicted.Leaders from the 27 member states of the European Union will meet in Brussels on Dec. 8-9 to discuss how to resolve the eurozone crisis.
