BEIJING,Nov. 9 (Xinhuanet) – Yinghuo-1, China's first interplanetary spacecraft, is set to hitch a ride with Russia's Phobos-Grunt Mars mission in the early hours on Wednesday, after a two-year delay.A Zenit-2SB rocket will carry Yinghuo-1 and Phobos-Grunt into space from the Baikonur Cosmodrome launch site in Kazakhstan.It is China and Russia's first joint Mars operation and also marks China's first voyage to the Red Planet, China Great Wall Industry Corp said in a news release on Tuesday.Yinghuo-1 will work in orbit with Phobos-Grunt for more than 12 months in collecting data on the Martian atmosphere.Both spacecraft will travel for more than 10 months before entering Martian orbit. During the trip, Yinghuo-1's power supply, communications and temperature gauge will be controlled from the Russian craft, scientists said.Both craft will orbit the planet three times before decoupling. The 106-kg Yinghuo-1 will circle Mars in an elliptical orbit, while Phobos-Grunt will actually land on Phobos, one of the two Martian moons, and bring back soil samples to Earth."The collaboration with Russia will enhance China's ability in deep space exploration, improve spacecraft design and development, and promote planetary exploration," said an unnamed official with the corp, a subsidiary of the China Aerospace Science & Technology Corp. Russia's Lavochkin Research and Production Association signed a cooperation contract, based on an agreement between the Chinese and Russian governments, with China Great Wall Industry Corp in 2007.Yinghuo-1, with a two-year lifespan, also has its own scientific goals.These include analyzing the planet's magnetic environment and ionosphere (upper atmosphere), taking images of topographical features and studying gravity fields on the Martian equator.Pang Zhihao, deputy editor-in-chief of the monthly publication, Space International, said China's focus on the planet's upper atmosphere is significant.Twenty detectors have explored parts of Mars, but most of them have looked for traces of life or water or places suitable for setting up colonies, he said.But studying the upper atmosphere is also vital if humans are to live on the planet, he said.The mission was set for October 2009, but later postponed to this year to enhance the reliability of the project.Only the United States, the former Soviet Union and the European Union have succeeded in landing probes on Mars. Five are in operation, four belong to the US and one belongs to the EU.At least 21 probes sent to the planet have failed. The Shanghai Academy of Spaceflight Technology under the CASC, which designed Yinghuo-1 in 23 months, said that the satellite posed a major technological challenge as the furthest space destination for China before had been the moon. The moon's average distance from Earth is about 384,000 km. The distance between Mars and Earth, depending on orbits, ranges from approximately 55 million km to about 350 million km.Yinghuo-1 will have to endure periods in the freezing dark side of the planet.It underwent simulated tests that matched the Martian temperature, - 260 C.Because of the distances involved, the satellite cannot rely on ground control to adjust position. It will rely on its own onboard computer, scientists said.

WASHINGTON, Nov. 10 (Xinhua) -- The U.S. Food and Drug Administration (FDA) has sent warning letters to more than 1,200 retailers, the majority of which respond to violations relating to selling tobacco to minors, as part of its ongoing effort to reduce tobacco use among children, the agency announced Thursday in a statement.The FDA said that while most retail establishments have been found to be in compliance with the law, some retailers are still selling cigarettes and smokeless tobacco to minors. Warning letters may be followed by civil money penalties if retailers continue to violate the law."It should worry every parent that 20 percent of U.S. high school students smoke cigarettes," said FDA Commissioner Margaret Hamburg in a statement. "President Obama and the FDA are committed to preventing children from smoking. For many young people, that first cigarette or use of smokeless tobacco will lead to a lifetime of addiction, and for many, serious disease. More than 80 percent of adult smokers begin smoking before 18 years of age. Retailers are vital partners in the FDA's efforts to prevent tobacco use among kids."Obama signed the Family Smoking Prevention and Tobacco Control Act that gives the FDA authority to regulate tobacco products to prevent use by minors and reduce the impact on public health. One of the law's provisions permits the FDA to contract with states and territories to conduct compliance check inspections of tobacco retailers. In 2011, the FDA awarded compliance contracts totaling more than 24 million U.S. dollars to 38 states.The FDA also began inspecting U.S. tobacco product manufacturers in October 2011. This is the first time tobacco product manufacturing facilities have ever been inspected by a federal public health agency.

NEW DELHI, Jan. 9 (Xinhua) -- Chinese ambassador to India Zhang Yan Monday proposed that China and India make more efforts to develop economic ties.At a meeting on China-India relations attended by Indian National Security Advisor S. Menon, the ambassador said the Chinese side is fully aware of the necessity to narrow the trade gap between the two sides in order to ensure the sustainability of bilateral trade cooperation."China will take measures to increase the import of Indian products which have market demand in China. But our cooperation should not be limited in trade only," said the ambassador.He suggested that China and India should diversify their trade structure, expand the scope and items, and increase the technical content and added value to the products, while expanding into financial, service and investment sectors.The envoy said China and India should initiate policy dialogue and coordinate their economic development strategy in order to ensure steady growth of respective economy, encourage mutual investments, consider the free trade agreement or regional trade arrangement, and increase tourism cooperation.Zhang said that as an encouraging sign of economic ties, the bilateral trade volume is set to hit 70 billion U.S. dollars in 2011, an over 20 percent increase over the previous years, while China set up its first branch of the Industrial and Commercial Bank of China in Mumbai last year.

ULAN BATOR, Dec. 1 (Xinhua) -- Mongolia will continue to curb the spread of HIV and strive to maintain a low prevalence of the AIDS epidemic, a government official said Thursday.Gansukh Battulga, an official with the National Committee on AIDS, told Xinhua that Mongolia is currently an HIV low-prevalence country with a total of 99 people, 15 of whom have died, infected with the virus that causes AIDS."Among the 99 HIV infected cases, 81 percent are men, and the remaining 19 percent are women," Battulga said. "Among the male infected cases, 83 percent belong to MSM (men who have sex with men) group while sex workers account for 54 percent of the female infected cases."The official said the government has launched a variety of programs and tasked the National Committee on AIDS to coordinate all organizations in fighting the epidemic.According to a National Strategy Plan for 2010-2015, Mongolia will strive to maintain its current low HIV-prevalence rate of below 5 percent in the most-at-risk population.

SAN FRANCISCO, Nov. 1 (Xinhua) -- Yahoo, which has been rumored to sell all or part of its business, announced on Tuesday that it is buying data-driven advertising network Interclick for around 270 million U.S. dollars.Interclick is a technology company providing data targeted solutions and optimization technologies."This investment underscores our focus on enhancing the performance of both our guaranteed and non-guaranteed display business across Yahoo and our partner sites and, combined with Yahoo's reach and advertising leadership, will deliver a powerful solution for marketers," said Ross Levinsohn, Yahoo's executive vice president for the Americas region.Some analysts said Interclick's technology could help Yahoo to grow its display advertising market share as Google and Facebook have gained on or surpassed the company in the area.But the acquisition also raised questions considering Yahoo's financial situation after it reported last month its revenue in the last quarter decreased by 5 percent year-over-year. The company is also in a chief executive officer (CEO) search following the firing of former CEO Carol Bartz in September and amidst reports of a possible takeover.Although in a financial struggle, Yahoo still has around 700 million unique monthly visitors and its news division is the biggest online news site with around 81.2 million unique visitors in August.Tech giants like Google and Microsoft are reported to be considering providing finance for the acquisition of Yahoo by another company or a group of companies.In a report on Monday, Bloomberg News reported that Yahoo is leaning toward selling Asian assets and redistributing the proceeds to shareholders, rather than selling itself to a group of buyers. Yahoo's shares fell more than 5 percent after the possibility was reported.
