WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."

BEIJING, Oct. 6 (Xinhua) -- China's first space lab module were in good condition and all tests went on "smoothly" during the past week, according to a statement issued by the country's space project authorities Thursday.The unmanned module, Tiangong-1, or Heavenly Palace-1, blasted off on Sept. 29 from Jiuquan Satellite Launch Center in northwest China's desert area.Tiangong-1 switched to the orbit of 362 kilometers high and had orbited the Earth for 109 times by 6:00 p.m. Thursday, the statement said.Tests on the module's remote control system, video/audio equipments, temperature/humidity sensors, docking facilities and other functions had been conducted successfully, it added.It also revealed that the Jiuquan Launch Center and other units were preparing for the launch of the Shenzhou-8 unmanned spacecraft, which is scheduled to join the Tiangong-1 later this year.Shenzhou-8 and Tiangong-1 are expected to perform China's first space docking at a height of 340 kilometers above the earth's surface.

WASHINGTON, Dec. 1 (Xinhua) -- U.S. President Barack Obama announced Thursday that his administration is committing an addition 50 million U.S. dollars in funding for domestic HIV/AIDS treatment and care.Obama also set a new target of helping six million people in countries hardest hit by the HIV virus get access to life-saving antiretroviral drugs by the end of 2013, increasing the original U. S. goal by two million."We can beat this disease,"' Obama declared at a World AIDS Day event in Washington. Former Presidents George W. Bush and Bill Clinton also participated via satellite.Citing the success of the President's Emergency Plan for AIDS Relief program in providing antiretroviral treatment to people living with HIV/AIDS around the world, Obama admitted that new infections are still not going down in the United States."The rate of new infections may be going down elsewhere, but it 's not going down here in America,'' he said. "There are communities in this country being devastated still by this disease. When new infections among young, black, gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.''Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also told Xinhua recently that in the United States, the AIDS epidemic has plateaued, but it is still at "unacceptably high" level.About 1.2 million Americans are living with HIV and only 28 percent of them have the infection under control, the U.S. Centers for Disease Control and Prevention reported this week."The fight is not over," Obama declared, but "the federal government can't do this alone." He called on state governments, pharmaceutical companies, and private foundations, to do their part to help Americans get access to all the life-saving treatments.Obama also appealed to global partners to step up their efforts to end AIDS, some 30 years after the epidemic first surfaced. "So on this World AIDS Day, here's my message to everyone out there. To the global community -- join us," he said.

SAN FRANCISCO, Nov. 21 (Xinhua) -- Hewlett-Packard Co. (HP) on Monday reported that its profit in the most recent quarter fell more than 90 percent with sales also declining.In the company's fourth quarter of fiscal 2011 ended Oct. 31, the company posted net earnings of 239 million U.S. dollars, compared with 2.54 billion dollars in the same period a year earlier.HP's net revenue for the quarter reached 32.1 billion dollars, down 3 percent year-on-year.Excluding one-time items, HP earned 1.17 dollars per share, which topped estimates of analysts.According to Thomson Reuters, analysts had expected earnings of 1.13 dollars per share on revenue of 32.05 billion dollars.It was the first earnings report since Meg Whitman took over as chief executive officer (CEO) of the information technology giant on Sept. 22, replacing Leo Apotheker."HP has a great opportunity to build on our strong hardware, software, and services franchises with leading market positions, customer relationships, and intellectual property," Whitman said in a statement after the earnings announcement."We need to get back to the business fundamentals in fiscal 2012, including making prudent investments in the business and driving more consistent execution," she added.

MOSCOW, Oct. 24 (Xinhua) -- The Russian Space Agency Roscosmos confirmed on Monday the list of next crew members who will fly to the International Space Station (ISS) on Nov. 14.Russia's Soyuz TMA-22 spacecraft will bring Russian cosmonauts Anton Shkaplerov and Anatoly Ivanishin and American astronaut Daniel Burbank to the ISS for a 124-day-long mission.Russia's Gennady Padalka and Sergei Revin and American Josef Akaba are announced as the backup crew.According to the Roscosmos, the new crew will host one manned and three unmanned cargo ships during their stay in the ISS and conduct a space walk as well as 37 scientific experiments.During the new crew's stay, the ISS would also make its 75,000th revolution around the Earth, the Roscosmos said.The launch of the Soyuz TMA-22 was initially scheduled on Sept. 22, but was postponed after the failed launch of the Progress cargo ship to the ISS on Aug. 24.
