WASHINGTON, July 27 (Xinhua) -- The solar-powered, Jupiter- bound Juno spacecraft was secured into place on top of its rocket Wednesday in preparation for launch next month, the U.S. National Aeronautics and Space Administration (NASA) announced.The launch period for Juno opens Aug. 5 and extends through Aug. 26. For an Aug. 5 liftoff, the launch window opens at 11:34 a.m. EDT (1534 GMT) and remains open through 12:43 EDT (1643 GMT).Juno will arrive at Jupiter in July 2016 and orbit its poles 33 times to learn more about the gas giant's interior, atmosphere and aurora."We're about to start our journey to Jupiter to unlock the secrets of the early solar system," said Scott Bolton, the mission 's principal investigator from the Southwest Research Institute in San Antonio. "After eight years of development, the spacecraft is ready for its important mission."

BEIJING, Sept. 20 (Xinhua) -- Floods and landslides triggered by recent heavy rains in eight of China's provincial-level regions have left 70 people dead and 32 others missing this month.Heavy downpours, floods and other related disasters have affected Sichuan, Shaanxi, Henan, Chongqing, Hubei, Shandong, Shanxi and Gansu, the National Disaster Reduction Commission said in a statement released on Tuesday.As of Tuesday, these disasters have affected 21.56 million people and caused an estimated 26.09 billion yuan (4.08 billion U.S. dollars) in direct economic losses, the statement said.

SAN FRANCISCO, Sept. 22 (Xinhua) -- Facebook on Thursday introduced Timeline, a new profile design featuring milestones of one's life on a single page.At Facebook's f8 developer conference, Chief Executive Officer Mark Zuckerberg promoted the new feature, a blog-like presentation that let users scrolls vertically through the big moments of one's life."It's how you can tell the whole story of your life in a single page," said Zuckerberg, showing his Timeline which started from a baby photo.Zuckerberg assured users that they have complete control over their Timeline, saying that they can decide what content will appear and who can see it.

BERLIN, June 5 (Xinhua) -- German authority said on Sunday that bean sprouts might be the "most convincing" source for the E. coli outbreak which has killed 22 people and infected more than 2,000 in the Europe.Gert Lindemann, Agriculture Minister of the state Lower Saxony, told reporters in a press conference that restaurants and food outlets where the cases of E. coli had been reported all had received shipments of the particular bean sprouts.A related company in the Uelzen region has been shut down and its products have been recalled, he said."It is the most convincing... source for the E. coli outbreak," Lindemann said. Although a conclusive laboratory analysis will not come out until Monday, current indications were strong enough to issue a public warning, he said.Authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries - all of whom had once traveled in northern Germany. More than 600 of those infected have developed Hemolytic Uremic Syndrome (HUS), a potentially deadly complication attacking the kidneys.The source of E.coli was first thought to be the cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by Laboratory tests in Hamburg on Tuesday.

WASHINGTON, July 20 (Xinhua) -- Using the Hubble Space Telescope, astronomers have discovered a fourth moon orbiting the icy dwarf planet Pluto, the U.S. National Aeronautics and Space Administration (NASA) announced Wednesday in a statement. The tiny, new satellite, temporarily designated P4, was uncovered in a Hubble survey searching for rings around the dwarf planet.P4 was first seen in a photo taken with Hubble's Wide Field Camera 3 on June 28. It was confirmed in subsequent Hubble pictures taken on July 3 and July 18. It is the smallest moon discovered around Pluto. It has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto's largest moon, is 648 miles (1,043 km) across, and the other moons, Nix and Hydra, are in the range of 20 to 70 miles in diameter (32 to 113 km).Two labeled images of the Pluto system taken by the Hubble Space Telescope's Wide Field Camera 3 ultraviolet visible instrument with newly discovered fourth moon P4 circled. The image on the left was taken on June 28, 2011. The image of the right was taken on July 3, 2011."I find it remarkable that Hubble's cameras enabled us to see such a tiny object so clearly from a distance of more than 3 billion miles (5 billion km)," said Mark Showalter of the SETI Institute in California, who led this observing program with Hubble.P4 is located between the orbits of Nix and Hydra, which Hubble discovered in 2005. Charon was discovered in 1978 at the U.S. Naval Observatory and first resolved using Hubble in 1990 as a separate body from Pluto.The dwarf planet's entire moon system is believed to have formed by a collision between Pluto and another planet-sized body early in the history of the solar system. The smashup flung material that coalesced into the family of satellites observed around Pluto.The finding is a result of ongoing work to support NASA's New Horizons mission, scheduled to fly through the Pluto system in 2015. The mission is designed to provide new insights about worlds at the edge of our solar system. Hubble's mapping of Pluto's surface and discovery of its satellites have been invaluable to planning for New Horizons' close encounter."This is a fantastic discovery," said New Horizons' principal investigator Alan Stern of the Southwest Research Institute in Colorado. "Now that we know there's another moon in the Pluto system, we can plan close-up observations of it during our flyby."
