LOS ANGELES, June 20 (Xinhua) -- NASA's Cassini spacecraft has successfully completed its second-closest encounter with Saturn's icy moon Helene, beaming down raw images of the small moon, the Jet Propulsion Laboratory (JPL) said on Monday.At closest approach on June 18 Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface, the second closest approach to Helene of the entire mission, said JPL in Pasadena, Los Angeles.This flyby will enable scientists to finish creating a global map of Helene, so they can better understand the history of impacts to the moon and gully-like features seen on previous flybys, according to JPL.Passing from Helene's night side to the moon's sunlit side, Cassini also captured images of the Saturn-facing side of the moon in sunlight, a region that was only illuminated by sunlight reflected off Saturn the last time Cassini closely encountered with the moon in March 2010.The closest Helene encounter of the mission took place on March 10, 2010, when Cassini flew within 1,131 miles (1,820 kilometers) of the moon.The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.JPL, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL, while the imaging team is based at the Space Science Institute in Boulder, Colorado.

BEIJING, Sept. 27 (Xinhuanet) -- People having a dog is way healthier than those don't, both physically and mentally, media reports said Tuesday.People owning dogs are more likely to take exercises than those having none, according to a recent poll of Mars Petcare, a pet food company.Two thirds of the walks dog owners take each week are attributed to their dogs, according to the poll, in which over 1,000 adults were surveyed.The survey also showed that 44 percent of dog owners over 65 years old make exercises because of their dogs.Dogs are a great motivator for doing exercises, said Dr. Sandra McCune, an animal behaviorist and also co-author of the book, "The Health Benefits of Dog Walking for People and Pets".

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.

MOSCOW, Aug. 6 (Xinhua) -- The Arctic is getting warmer at a fast pace with the Russian Arctic sector's ice areas contracting to historically low levels, according to Russian meteorological bureau Rosgidromet.According to a Rosgidromet report cited by Itar-Tass news agency Saturday, the polar cap in the Russian sector has shrunk to the historical low registered in 2007, with no ice expected to block the Northern Seaway at least until September."Currently, Arctic navigation conditions are very favorable. By early August, navigation can be done without icebreakers almost along the entire route," said Valery Martyshchenko, head of Rosgidromet's environment pollution monitoring department.According to the Arctic and Antarctic Research Institute, the current ice cover in the Arctic Ocean is 6,860 million square kilometers, way below average.Martyshchenko said the longer period of icebreaker-free navigation would benefit the regions located in the Arctic area, allowing longer access to food and energy supplies, but the warming of the climate also posed new threats, such as melting of ice and forming of icebergs.
