LOS ANGELES, June 10 (Xinhua) -- The Aquarius/SAC-D observatory, NASA's first ever satellite to study the saltiness of Earth's oceans, is in excellent health after its launch early Friday, initial telemetry reports showed.The observatory rocketed into space from Vandenberg Air Force Base in California atop a United Launch Alliance Delta II rocket at 7:20:13 a.m. PDT (10:20:13 a.m. EDT).Less than 57 minutes later, the observatory separated from the rocket's second stage and began activation procedures, establishing communications with ground controllers and unfurling its solar arrays, NASA's Jet Propulsion Laboratory (JPL) said.During the next 25 days, the Aquarius/SAC-D service platform will be tested and maneuvered into its final operational, near-polar orbit 408 miles (657 kilometers) above Earth. Science operations will begin after the observatory's instruments are checked out. This commissioning phase may last up to 65 days, JPL said.Aquarius will map the global open ocean once every seven days for at least three years with a resolution of 93 miles (150 kilometers). The maps will show how ocean surface salinity changes each month, season and year. Scientists expect to release preliminary salinity maps later this year."Aquarius is a critical component of our Earth sciences work, and part of the next generation of space-based instruments that will take our knowledge of our home planet to new heights," said NASA Deputy Administrator Lori Garver. "The innovative scientists and engineers who contributed to this mission are part of the talented team that will help America win the future and make a positive impact across the globe."Aquarius will measure salinity by sensing thermal microwave emissions from the water's surface with three microwave instruments called radiometers. When other environmental factors are equal, these emissions indicate the saltiness of surface water. A microwave radar scatterometer instrument will measure ocean waves that affect the precision of the salinity measurement.Because salinity levels in the open ocean vary by only about five parts per thousand, Aquarius will be able to detect changes as small as approximately two parts per 10,000, equivalent to about one-eighth of a teaspoon of salt in a gallon of water."Data from this mission will advance our understanding of the ocean and prediction of the global water cycle," said Michael Freilich, director of NASA's Earth Science Division in the Science Mission Directorate at agency headquarters in Washington. "This mission demonstrates the power of international collaboration and accurate spaceborne measurements for science and societal benefit. This would not be possible without the sustained cooperation of NASA, CONAE and our other partners."The Aquarius/SAC-D (Satellite de Aplicaciones Cientificas) observatory is a collaboration between NASA and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE).Aquarius was built by NASA's JPL and the Goddard Space Flight Center in Greenbelt, Maryland. NASA's Launch Services Program at the Kennedy Space Center in Florida manages the launch.JPL will manage Aquarius through its commissioning phase and archive mission data. Goddard will manage Aquarius mission operations and process science data. CONAE is providing the SAC-D spacecraft, optical camera, thermal camera with Canada, microwave radiometer, sensors from various Argentine institutions and the mission operations center. France and Italy also are contributing instruments.

SAN FRANCISCO, Sept. 22 (Xinhua) -- Facebook on Thursday introduced a new feature called Open Graph, enabling users to access and share a wide range of media and lifestyle content on the social network site.According to Facebook's chief executive officer (CEO) Mark Zuckerberg, Open Graph lets users share what they are doing in Facebook-connected apps as they are doing it.These social apps focus on media apps including books, news, music, TV, movies and games, as well as lifestyle apps such as exercise, food, fashion and travel."The last five years of social networking have been about getting people signed up, and getting people connected with their lives. The next five years are going to be defined by the apps and depth of engagement," the young CEO said in a keynote speech at Facebook's f8 developer conference.Take music for example, Facebook integrates with European music streaming service Spotify. If one's Spotify account is connected to Facebook, a message will show up in the Ticker stating the song one is listening to and in the Timeline, a new design of one's profile page. The friends of the user can listen to the same song at the same time by hovering mouse over the song in Timeline or Ticker.Spotify founder and CEO Daniel Ek and movie streaming service Netflix CEO Reed Hastings also took stage as guest speakers to introduce their partnership with Facebook.Zuckerberg also introduced social news reading applications from major news organizations such as The Washington Post and Yahoo News, which allow users to access the content directly on Facebook.Earlier at the f8 conference, Timeline was unveiled as a new feature. It is a new profile design allowing users to scroll vertically through the big moments of one's life in a single page.Zuckerberg assured users that they have complete control over their Timeline, saying they can decide what content will appear and who can see it. The new feature will be available in a few weeks.Since Google launched its own social network "Google+" in June, Facebook has been in a combat mode, striving to roll out new products and features to beat the search giant. In his keynote speech on Thursday, Zuckerberg said half a billion people now use Facebook every day.Two days before the f8 conference, Google announced to open its social network to the public, noting it has introduced 100 new features in the three-month trial.

SAN FRANCISCO, July 29 (Xinhua) -- Apple has ousted Nokia as the world's largest smartphone maker as global mobile phone market grew more than 11.3 percent in the second quarter of 2011, according to two separate market research studies.After becoming the largest smartphone vendor in terms of revenue and profits, Apple has become the world's largest smartphone vendor by volume with 18.5 percent market share, said the latest research from Strategy Analytics released on Friday.The Cupertino, California-based company sold 20.3 million iPhones in the second quarter,up 142 percent compared with the same period a year earlier.Samsung's shipments of 19.2 million units grew a huge 520 percent year over year, accounting for 17.5 percent global smartphone market share in the second quarter of 2011.Apple and Samsung overtook long-time volume leader Nokia for the two spots. The Finnish mobile phone giant accounted for 15.2 percent of global smartphone market share in the last quarter, which is less than half of what it was just one year earlier.In the second quarter of 2010, Nokia was the No.1 smartphone maker by volume in the world with 38.1 percent of market share. The industry is now waiting Nokia's pending transition to Windows Phone 7.According to a separate report by International Data Corporation (IDC) released on Thursday, the worldwide mobile phone market grew by 11.3 percent year over year in the second quarter of 2011 despite a decline of the feature phone market for the first time in almost two years.The feature phone market was down by 4 percent in the last quarter, said the IDC Worldwide Mobile Phone Tracker report. It noted that the decline in shipments was mainly in economically mature regions, such as the United States, Japan and Western Europe, as users making rapid transition to smartphones.The shrinking feature phone market had a great impact on some of the world's largest suppliers of mobile phones, such as Nokia, which is losing share in the feature phone category to low-cost suppliers, said the report.For the overall market, global mobile phone vendors shipped 365. 4 million units in the second quarter, compared to 328.4 million units in the same period last year, with Nokia still holding the top spot with a market share of 24.2 percent, followed by Samsung, LG Electronics, Apple and ZTE.But the 11.3 percent growth was lower than IDC's forecast for the quarter and also below the 16.8 percent growth in the first quarter of 2011.IDC said the feature phone forecast isn't expected to be any rosier in the future and the shipment growth of feature phones won 't exceed 1.1 percent in the coming years.

BONN, Germany, June 17 (Xinhua) -- The latest United Nations (UN) climate talks ended here on Friday with no surprise -- some " technical issues" saw some progress, as delegates usually said, while major disagreements remained.The two-week UN climate negotiations have made "clear advances" on such issues as extending carbon trading mechanisms, climate fund management and slowing deforestation, Christiana Figueres, UN Framework Convention on Climate Change (UNFCCC) executive secretary, said at a closing press conference.Figueres said delegates from 183 countries stepped forward with a technology mechanism to boost global green technology sharing. The mechanism will include a Climate Technology Center and Network to establish a worldwide clean technology stakeholder community.As for the implementation of a comprehensive package of the Cancun summit last year, this Bonn session has "paved the way" for progress at the next UN ministerial-level climate conference, which is to be held in Durban, South Africa from Nov. 28 to Dec. 9, Figueres said."Strong convergence has emerged on how the Adaptation Committee will be governed, what its composition will be and what its specific role will be," she said. "This progress means that the Committee could be fully operationalized at Durban."The UN climate chief stressed that governments, business circles and civil society cannot solve issues related to climate change "in one meeting," and climate talks are "the most important " negotiations the world has ever seen."The Bonn meeting is practical, focusing on concrete issues. In general, the negotiating process is moving forward step by step and on the right track," Su Wei, China's chief negotiator, told Xinhua on Friday."Despite setbacks and reversals, parties are taking climate change seriously and are willing to promote the negotiations under the Bali Roadmap," he said. "In the past two weeks, contact groups are busy making informal consultations on various topics.""Admittedly, in some key areas, there is a gap among parties," Su said.During the meeting, many delegates and observers have complained that the pace of negotiation was unbearably slow, especially against the backdrop of a new warning from the International Energy Agency, which said the global energy-related carbon emissions rose to a record high in 2010 despite decade-long efforts on curbs.Experts said one of the main hurdles in current talks was still the old topic -- the fate of the Kyoto Protocol, the sole legally- binding pact on industrial countries' emission cuts set to expire at the end of 2012.The protocol, which binds 37 rich countries, has been crippled since Cancun, as Japan, Canada and Russia have clearly stated they would not extend the pact's second commitment period after 2012.The United States, which never ratified the treaty, said it would not accept any legal deal unless other major economies have similar emission constraints.The European Union (EU), the last major bloc that is open to the renewing of the Kyoto Protocol, said its supportive attitude should not be taken for granted. The EU said it would not unilaterally step up efforts on combating climate change if other nations are not willing to do the same.Meanwhile, developing countries insisted that the updating of the Kyoto Protocol remains "the very core issue" of current talks, asking rich nations to shoulder their historical responsibilities and preserve the pact as a major legally-binding instrument to tackle climate change.The Group of 77 and China, representing over 130 developing nations, have said that the renewal of the Protocol should be the priority for Durban.On Friday, Figueres said that "resolving the future of the Kyoto Protocol is an essential task this year and will require high-level political guidance.""By Durban, governments need to come forward with options that will be acceptable to all parties," she said, adding that high- level contacts are necessary to break the ice.She told reporters that environment ministers are due to meet in Berlin from July 3 to 4, known as a continuation of last year's ministerial-level informal talks held in the town of Petersburg near Bonn. Moreover, world leaders are due to discuss climate change on the sidelines of the UN General Assembly in September.Before the Durban summit, delegates have agreed to hold an additional round of climate talks in late September or early October, Figueres revealed.
