MOSCOW, March 11 (Xinhua) -- A new crew which are to depart for the International Space Station (ISS) at the end of March have successfully passed the pre-flight tests, the Russian Federal Space Agency (Roscosmos) announced on Friday.At a press conference held at Russia's Cosmonauts Training Center, a Roscosmos spokesman said two Russian cosmonauts Andrei Borisenko and Alexander Samokutyaev and a U.S. astronaut Ronald Garn will leave for the ISS by a Russian Soyuz-TM-21 spacecraft on March 30.On March 17, the three crew members and their backup crew members, Anton Shkaplerov, Anatoly Ivanishin and Daniel Burbank, will make their final preparation for the space trip in the Baikonur space site in Kazakhstan.According to the Roscosmos, the three main crew members are expected to spend 170 days in the ISS. During the period, they will receive two U.S. space shuttles and three Russian Progress cargo ships and conduct a spacewalk.The agency also revealed the Soyuz-TM-21 spacecraft scheduled for the ISS was named as Gagarin.The year of 2011 was announced as Russia's Space Year to celebrate the 50th anniversary of the launch of the first Russian manned space flight carrying cosmonaut Yuri Gagarin in 1961 for a 90-minute flight.

WASHINGTON, May 11 (Xinhua) -- NASA's Dawn spacecraft has obtained its first image of the giant asteroid Vesta, which will help fine-tune navigation during its approach, the U.S. space agency announced Wednesday.Dawn expects to achieve orbit around Vesta on July 16, when the asteroid is about 117 million miles from Earth.The image from Dawn's framing cameras was taken on May 3 when the spacecraft began its approach and was approximately 752,000 miles (1.21 million km) from Vesta. The asteroid appears as a small, bright pearl against a background of stars. Vesta also is known as a protoplanet, because it is a large body that almost formed into a planet."After plying the seas of space for more than a billion miles, the Dawn team finally spotted its target," said Carol Raymond, Dawn's deputy principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "This first image hints of detailed portraits to come from Dawn's upcoming visit."Vesta is 330 miles (530 km) in diameter and the second most massive object in the asteroid belt. Ground- and space-based telescopes obtained images of the bright orb for about two centuries, but with little surface detail.Mission managers expect Vesta's gravity to capture Dawn in orbit on July 16. To enter orbit, Dawn must match the asteroid's path around the sun, which requires very precise knowledge of the body's location and speed. By analyzing where Vesta appears relative to stars in framing camera images, navigators will pin down its location and enable engineers to refine the spacecraft's trajectory.Dawn will start collecting science data in early August at an altitude of approximately 1,700 miles (2,700 km) above the asteroid's surface. As the spacecraft gets closer, it will snap multi-angle images allowing scientists to produce topographic maps. Dawn will later orbit at approximately 120 miles (200 km) to perform other measurements and obtain closer shots of parts of the surface. Dawn will remain in orbit around Vesta for one year. After another long cruise phase, Dawn will arrive in 2015 at its second destination, Ceres, an even more massive body in the asteroid belt.Gathering information about these two icons of the asteroid belt will help scientists unlock the secrets of our solar system's early history. The mission will compare and contrast the two giant asteroids shaped by different forces. Dawn's science instruments will measure surface composition, topography and texture. Dawn also will measure the tug of gravity from Vesta and Ceres to learn more about their internal structures. The spacecraft's full odyssey will take it on a 3-billion-mile (5-billion-km) journey, which began with its launch in September 2007.

SAN FRANCISCO, April 4 (Xinhua) -- Web exploit toolkits, or " packaged" attack frameworks that can be traded online, are rapidly growing as the top cybercrime weapon due to ease of use and high success rate, a new report has found."When it comes to conducting online crime, exploit toolkits are the weapon of choice for many cyber criminals," said the "2010 Top Cyber Security Risks Report" published by Hewlett-Packard Co. (HP) on Monday.The trend started in 2006 with the release of WebAttacker, considered by many to be the first modern day web exploit toolkit, according to the report.An emerging trend ensued and soon took off, and today the Internet is subjected to hundreds of exploits originating from these toolkits."With the ever-increasing, web-based criminal activity, the number of exploit toolkits has skyrocketed and shows no signs of slowing down," the report stated.Though protecting against attacks originated with web exploit toolkits is becoming increasingly difficult, there are ways to minimize the risk of infection, said the report, noting that one of the most effective defenses is to install patches onto host systems.The report also found that while the number of attacks against known vulnerabilities continues to rise, the number of discovered vulnerabilities has plateaued in 2010."We've discovered that rather than investing resources to uncover new exploits, attackers are focused on current, unpatched vulnerabilities in web applications, social networking sites and Web 2.0 interfaces," Mike Dausin, a manager at HP Digital Vaccine Labs, said in a statement.Data from the report showed that nearly half of all reported vulnerabilities exist in web applications, and third-party plug- ins to content management systems have become the leading cause of web application vulnerabilities.

SAN FRANCISCO, April 5 (Xinhua) -- The appeal of tablet computer and electronic-book reader (e-reader) has been giving a boost to semiconductor market as sales of chips for such devices surged in 2010 and keeps growing, market research firm International Data Corp. (IDC) said on Tuesday.A new IDC report showed that worldwide revenues for media tablet and e-reader semiconductors grew by over 2,000 percent to 3. 3 billion U.S. dollars in 2010 as semiconductor suppliers enabled original equipment manufacturers to bring new products to market less than 8 months after Apple Inc. launched its iPad tablet.According to IDC's definition, media tablets are devices with color displays larger than 5-inch and smaller than 14-inch, running lightweight operating systems and able to be based on either x86 or ARM processors."The opportunity for semiconductors in media tablets and e- readers has exploded and semiconductor suppliers are scrambling to bring to market semiconductor and software platforms to enable these products," Michael Palma, a senior research analyst at IDC, said in a statement.Looking forward, IDC said it expects media tablet and e-reader semiconductor revenues to grow by 120 percent year over year in 2011, predicting that the market will be boosted by the arrival of a new version of Google Inc.'s Android operating system, dual core processors and increased bandwidth."For the next several years, we will see rapid innovation cycles for products launched into the marketplace and semiconductor suppliers will continue to satisfy evolving end user requirements over the coming years," Palma noted.

BEIJING, Feb.11 (Xinhua) -- Representatives from different sectors have given feedback on drafts of the government work report and China's economic and social development blueprint for the next five years, the State Council, China's cabinet, said Friday.Premier Wen Jiabao chaired five seminars from Jan. 20 to 27, at which representatives of various sectors of society were invited to voice their views on the documents, according to a State Council statement.The 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review at the plenary session of the National People's Congress (NPC), China's top legislature, in March.Experts from social economic organizations along with those from science and technology, education, health, culture and sports circles attended the meetings, as well as members of non-communist parties.Participants at the seminars agreed on the framework and main content of the documents. They also gave some suggestions and proposed a couple of revisions to the report and the development plan.Most suggestions focused on China's economic restructuring, income distribution adjustment, modern agricultural development, scientific innovation, reform of the yuan exchange rate formation mechanism, property market regulation and affordable housing construction, and further improvement in education and medical care system.The forums also invited 11 grass-roots representatives, including farmers, technicians, and owners of small businesses, who raised suggestions to boost farmland irrigation construction, train more technicians, and help with the development of small and medium enterprises.Wen said the feedback will be "of great help" when revising both the government work report and 12th five-year plan, as well as to the work of the government.
