BAIKONUR, Kazakhstan, Nov. 9 (Xinhua) -- Russia's Phobos-Grunt probe and China's Yinghuo-1 satellite were launched from the Baikonur cosmodrome in Kazakhstan on a Zenit-2SB rocket at 00:16 am Moscow time Wednesday (2016 GMT Tuesday).The main aim of the Phobos-Grunt unmanned mission is to bring back the first ever soil sample from Phobos, the larger of Mars' two moons.Russia had spent about 5 billion rubles (about 161 million U.S. dollars) preparing for the three-year mission, which would include drilling Phobos' surface and returning 200 grams of soil back to Earth, according to Russian state space agency Roscosmos.The mission would also collect bacteria samples for two Russian and one U.S. biological experiments.In the meantime, China's first Mars probe Yinghuo will go into orbit around Mars and observe the planet itself.Phobos-Grunt is planned to reach Mars in 2012, then deploy its lander for Phobos in 2013 and return the soil sample back to Earth in August 2014.The Chinese probe, which would not land on Mars nor return to the Earth, is expected stay permanently in the space and communicate with the ground control directly via satellites.The Chinese probe is 75 cm long, 75 cm wide and 60 cm high. It weighs 115 kilograms and was designed for a two-year life to discover why water disappeared from Mars and shed light on other environmental changes on the planet.Victor Khartov, chief designer and director general of Lavochkin Research & Production Association, told Xinhua that the three-year mission is highly complicated."It consists of eight sub-missions: launch, travel to Mars vicinities, separation with the Chinese probe YH-1, landing on Phobos, soil collection, launch from Phobos, way back to the Earth, and final landing. Failure of any one of them could doom the entire project," he said.The launch of Phobos-Grunt and Yinghuo-1, originally scheduled for October 2009 on a Russian carrier rocket, has been postponed until 2011 due to "technical reasons" on the Russian side.

BEIJING, Nov. 17 (Xinhua) -- Chinese State Councilor Liu Yandong on Thursday met with a U.S. artist delegation, vowing to promote bilateral cultural and art exchanges.Headed by President and Chief Executive Officer of the Asia Society Vishakha Desai, the delegation will participate in the China-U.S. Forum on the Arts and Culture from Nov. 16-19 in Beijing.Liu welcomed the U.S. artists, noting cultural and art exchanges are an important component of bilateral people-to-people exchanges.She said the founding of the forum established an institutionalized and constructive platform for deepening bilateral relations and friendship between the two peoples.Artists from the two countries should exert their influence and actively promote bilateral cultural exchanges, she said.The forum is organized by the Chinese People's Association for Friendship with Foreign Countries, the Asia Society and the Aspen Institute.An extraordinary line-up of American cultural icons will attend the event, including actress Meryl Streep, film director Joel Coen, musician Yo-Yo Ma, and best-selling author Amy Tan.

BEIJING, Sept. 29 (Xinhuanet) -- Even a slightly high blood pressure is considered dangerous to largely increase the stroke risk, a new study found.The finding was published Wednesday on the online edition of U.S. medical journal Neurology.In the study, researchers found people who have pre-hypertension, whose blood pressure measured between normal and high, are 55 percent more likely to suffer a stroke compared with normal people.The study involved data from 12 previous studies on blood pressure and stroke occurrence of some 500,000 adults.About one in three U.S. adults suffer from pre-hypertension, which is defined at a systolic blood pressure between 120 and 139 or a diastolic blood pressure between 80 and 89, according to the U.S. Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure."People who do fall into the higher range of pre-hypertension should modify their lifestyle as much as possible," suggested Dr. Bruce Ovbiagele, director of the Olive View-UCLA Stroke Program and leading author of the study.Stroke is the number three cause of death, killing more than 130,000 in the U.S. a year, according to a CBS report.

WASHINGTON, Dec. 5 (Xinhua) -- NASA's Kepler mission has confirmed its first planet in the "habitable zone," a region where liquid water could exist on a planet's surface, the U.S. space agency announced on Monday.The newly-confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to Sun. The planet is about 2.4 times the radius of Earth. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.Previous research hinted at the existence of near-Earth-size planets in habitable zones, but clear confirmation proved elusive. Two other small planets orbiting stars smaller and cooler than Sun recently were confirmed on the very edges of the habitable zone, with orbits more closely resembling those of Venus and Mars.Kepler-22's star is a bit smaller than our sun, so its habitable zone is slightly closer in. The diagram shows an artist's rendering of the planet comfortably orbiting within the habitable zone, similar to where Earth circles the sun. Kepler-22b has a yearly orbit of 289 days. The planet is the smallest known to orbit in the middle of the habitable zone of a sun-like star. It's about 2.4 times the size of Earth."This is a major milestone on the road to finding Earth's twin, " said Douglas Hudgins, Kepler program scientist at the NASA Headquarters in Washington. "Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe."Kepler discovers planets and planet candidates by measuring dips in the brightness of more than 150,000 stars to search for planets that cross in front, or "transit," the stars. Kepler requires at least three transits to verify a signal as a planet."Fortune smiled upon us with the detection of this planet," said William Borucki, Kepler principal investigator at the NASA Ames Research Center who led the team that discovered Kepler-22b. "The first transit was captured just three days after we declared the spacecraft operationally ready. We witnessed the defining third transit over the 2010 holiday season."The Kepler science team uses ground-based telescopes and the Spitzer Space Telescope to review observations on planet candidates the spacecraft finds. The star field that Kepler observes in the constellations Cygnus and Lyra can only be seen from ground-based observatories in spring through early fall. The data from these other observations help determine which candidates can be validated as planets.Kepler-22b is located 600 light years away. While the planet is larger than Earth, its orbit of 290 days around a Sun-like star resembles that of Earth. The planet's host star belongs to the same class as Sun, called G-type, although it is slightly smaller and cooler.Of the 54 habitable-zone planet candidates reported in February 2011, Kepler-22b is the first to be confirmed. This finding will be published in The Astrophysical Journal.

BEIJING, Oct. 25 (Xinhuanet) -- Steve Jobs, Apple's co-founder and former CEO, may be one of the great men who will still be influential after their deaths.The new biography of Steve Jobs is likely to be the top-selling book 2011 of Amazon.com Inc, an online book retailer, according to Amazon spokeswoman Brittany Turner Monday."It could very likely be our top-selling book of the year," Turner said in a statement cited by the Reuters.Steve Jobs, written by Walter Isaacson, former Time magazine managing editor, was landed on shelves in bookstores Monday.But its digital version was reported to be released late on Sunday on Apple's iBooks online store and Amazon's Kindle eBook store.Since its release, the biography, both electronic and physical versions, has performed very well in Amazon.It is the best-selling book on Amazon.com and the top-selling electronic book on the Kindle as well. According to the Reuters, Isaacson was asked by Jobs to consider writing a biography for Apple's former CEO in 2004, when Jobs was going to be operated on for pancreatic cancer.Then Isaacson had more than 40 exclusive interviews with Steve Jobs. The last such interview was on October 5, one week before the giant's death.
