PARIS, Aug. 7 (Xinhua) -- European heavy-lift launcher Ariane 5 lifted off two communication satellites on Saturday.The Ariane 5, carrying Astra 1N and BSAT-3c/JCSAT-110R, was launched at 2252 GMT on Saturday from Kourou launch centre in French Guiana, according to live broadcast of the launching process.This was the fourth mission of Ariane 5 in 2011 and its 203th flight that sent off the two satellites Saturday night to their respective geostationary transfer orbits.Astra 1N, to be separated first, is built by EADS Astrium in Toulouse, France, for the Luxembourg-based operator SES Astra. With a designed lifespan of 15 years, it has an estimated liftoff mass of 5,350 kg and is fitted with 52 active Ku-band transponders.It is initially to deliver interim capacity from an orbital position of 28.2 degree East, and will subsequently move to SES Astra's prime location at 19.2 degree East for primary and backup services.BSAT-3c/JCSAT-110R is manufactured by Lockheed Martin Commercial Space Systems in Newtown, Pennsylvania, for Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation. This satellite weighs approximately 2,910 kg at launch time. It is to be positioned at 110 degree East longitude in geostationary orbit with a lifetime exceeding 16 years.This Ariane 5 flight has been postponed twice, firstly due to some technical problem in early July and then delayed by bad weather.Arianespace plans to achieve six Ariane 5 missions through this year.

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.

WASHINGTON, Sept. 12 (Xinhua) -- An enzyme that appears to play a role in controlling the brain's response to nicotine and alcohol in mice might be a promising target for a drug that simultaneously would treat nicotine addiction and alcohol abuse in people, U.S. researchers find.Over the course of four weeks, mice genetically engineered to lack the gene for protein kinase C (PKC) epsilon consumed less of a nicotine-containing water solution than normal mice, and were less likely to return to a chamber in which they had been given nicotine. In contrast, normal mice steadily increased their consumption of nicotine solution while the mice lacking PKC epsilon did not.The study conducted by researchers at the Ernest Gallo Clinic and Research Center, affiliated with the University of California, San Francisco, appeared Monday in the online edition of the Proceedings of the National Academy of Sciences.In normal mice, as in humans, nicotine binds to a certain class of nicotinic receptors located on dopamine neurons, which causes dopamine to be released in the brain. Dopamine creates a feeling of enjoyment, and thus prompts a sense of reward. Researchers found that mice lacking PKC epsilon are deficient in these nicotinic receptors.The finding complements earlier research in which researchers found that mice genetically engineered to lack the PKC epsilon enzyme drank less alcohol than normal mice and were disinclined to return to a chamber in which they had been given alcohol."This could mean that these mice might not get the same sense of reward from nicotine or alcohol," said Gallo senior associate director and investigator Robert Messing. "The enzyme looks like it regulates the part of the reward system that involves these nicotinic receptors."The reward system is a complex of areas in the brain that affect craving for nicotine, alcohol and other addictive substances.The next step in the research, said Messing, would be to develop compounds that inhibit PKC epsilon. The ultimate goal, he added, would be medications that could be used "to take the edge off of addiction by helping people get over some of their reward craving."

BEIJING, Sept. 28 (Xinhuanet) -- The unmanned Shenzhou VIII, part of China's first spacecraft rendezvous and docking mission, will be launched in early November. Niu Hongguang, deputy commander-in-chief of the program, said on Tuesday the launch has not been affected by the postponed lift-off of the Tiangong-1 space module. Tiangong-1 was to enter a low orbit around Earth at the end of August before being met by Shenzhou VIII. However, the departure was pushed back after a satellite failure on Aug 18. Out of safety concerns, Niu said mission commanders ordered a halt to testing at Jiuquan Satellite Launch Center on Tiangong-1 and its carrier rocket, Long March II-F T1. China Aerospace Science and Technology Corp, which designed and made the rocket carrier that failed to launch, formed an expert panel to investigate and made modifications. A successful launch of a communication satellite on Sept 19 using the Long March II-C showed the measures worked, Niu said, adding: "We now have confidence in the launch of Tiangong-1." The module is a "simplified" space lab that will not only be a docking target, but will also work as a space experimental platform. It will be unmanned for most of its two years of use, although astronauts will spend time onboard for short periods. After Shenzhou VIII, the country will launch Shenzhou IX and Shenzhou X next year to rendezvous and dock with Tiangong-1. Niu confirmed Shenzhou X will be manned. Tiangong-1 can accommodate two to three astronauts. "Whether Shenzhou IX will be manned is up to the results of the first rendezvous and docking mission," he said. The rocket carrier with Tiangong-1 atop stands 52 meters tall, with a takeoff weight of 493 tons. Tiangong-1 was scheduled for launch in between Sept 27 and 30, but due to weather forecasts that predicted a cold air mass would move into the area of Jiuquan Satellite Launch Center, it is believed that conditions on Thursday and Friday will be suitable for takeoff.

MOSCOW, June 27 (Xinhua) -- Russia successfully launched a Cosmos class military satellite on Monday, said spokesman of the Russian Space Forces Alexei Zolotukhin.A Soyuz-U carrier rocket carrying the military satellite blasted off from the Plesetsk Plesetsk space center in northern Russia at 20:00 Moscow time (1600 GMT), Zolotukhin said."The rocket put the Cosmos series military satellite into the designated orbit at 20:08 Moscow time (1608 GMT)," he added.The spokesman also said the launch of the Soyuz-U carrier rocket "was the first time for this type of rockets" in this year.The launch carried out by a team from the Russian Space Forces was supervised by Space Forces Commander Oleg Ostapenko.The satellite, Cosmos-2472, is a new member to a Russian network of about 60-70 military reconnaissance satellites.
