SAN FRANCISCO, Sept. 12 (Xinhua) -- Amazon.com Inc. is talking with book publishers to launch a rental subscription service for digital books, U.S. media reported on Monday.Several publishing executives said they aren't enthusiastic about the idea because it could lower the value of books and it could also strain their relationships with other retailers that sell their books, The Wall Street Journal quotes people familiar with the matter in a report.The Seattle-based company is considering a digital book library featuring old titles, which would be available to Amazon Prime subscribers, who currently pay 79 U.S. dollars a year for access to digital library of movies and TV shows and unlimited two-day shipping, said the report.Amazon would offer book publishers a substantial fee and could limit the amount of books that Amazon Prime customers could read for free every month, the report cited some sources as saying.The online retailing giant makes the popular electronic reader Kindle and is also reported to launch a color touchscreen tablet before October to compete with Apple's iPad and other devices in the increasingly crowded tablet computer market.The proposal is another sign that retailers are looking for more ways to deliver content digitally as customers increasingly read book and watch TV on personal computers, tablets and other electronic devices, said The Wall Street Journal report.

BEIJING, June 12 (Xinhua) -- China's Supreme People's Court (SPC) on Sunday publicized a judicial interpretation which sets specific rules for the country's courts to order penalties to criminals sabotaging TV and radio facilities.The interpretation said that criminals, whose sabotage causes information block for disaster early warning, rescue and others concern public security, could be convicted three to seven years of imprisonment on the charge of sabotaging TV and radio broadcast facilities.Other circumstances that could be convicted the imprisonment include sabotage that causes malfunction in the broadcast of TV and radio stations, according to the new law.According to statistics with the SPC, there have been more than 5,000 cases of sabotaging cable TV wires and more than 1,000 cases of sabotaging state-owned fiber optic lines and other cases of stealing broadcast facilities since 2006 in China.

WASHINGTON, Aug. 10 (Xinhua) -- After a journey of almost three years, NASA's Mars rover Opportunity has reached the Red Planet's Endeavour crater to study rocks never seen before, the U.S. National Aeronautics and Space Administration (NASA) announced on Wednesday.Scientists hope it will find rocks and terrain much older than any other that the itinerant robot has examined during its seven years on the red planet.The U.S. space agency said that Opportunity arrived at the rim of Endeavour on Tuesday. The golf cart-size rover is expected to remain at the 22-kilometer-wide crater for the next few years.A portion of the west rim of Endeavour crater sweeps southward in this color view from NASA's Mars Exploration Rover Opportunity."NASA is continuing to write remarkable chapters in our nation' s story of exploration with discoveries on Mars and trips to an array of challenging new destinations," NASA Administrator Charles Bolden said in a statement. "Opportunity's findings and data ... will play a key role in making possible future human missions to Mars and other places where humans have not yet been."NASA's Mars Reconnaissance Orbiter, which has been circling the planet since late 2005, detected clay minerals that form in wet conditions in the crater. Scientists want to find out if the minerals date back to Mars' distant past, when the planet is believed to have been wetter and warmer than the dry frozen desert it is today."We're soon going to get the opportunity to sample a rock type the rovers haven't seen yet," said Matthew Golombek, Mars Exploration Rover science team member, at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Clay minerals form in wet conditions so we may learn about a potentially habitable environment that appears to have been very different from those responsible for the rocks comprising the plains."NASA is searching for signs that Mars had a habitable environment billions of years ago. Knowledge of the Martian climate will be important to future manned missions there, and can shed light on the forces that shaped Earth's climate.NASA launched the Mars rovers Opportunity and Spirit in 2003 for what were planned to be three-month missions. But both continued operating well beyond that. Spirit stopped communicating in March 2010.

JIUQUAN, Gansu, Sept. 26 (Xinhua) -- Engineers are conducting the final preparations before launching China's first space laboratory module at the end of this week at a launch center in northwest China.The unmanned Tiangong-1 module was originally scheduled to be launched into low Earth orbit between Sept. 27 and 30. However, a weather forecast showing the arrival of a cold air mass at the Jiuquan Satellite Launch Center forced the launch to be rescheduled for Sept. 29 or 30, depending on weather and other factors."This is a significant test. We've never done such a thing before," said Lu Jinrong, the launch center's chief engineer.A full ground simulation was conducted on Sunday afternoon to ensure that the module and its Long March 2F carrier rocket are prepared for the actual launch.Cui Jijun, commander-in-chief of the launch site system and director of Jiuquan Satellite Launch Center, told Xinhua that they developed a new target spacecraft for the mission and made more than 170 technical improvements to the Long March 2F, China's manned orbital carrier rocket.Engineers have also made more than 100 updates at the launch site in order to make it compatible with the Tiangong-1, Cui added.The module will conduct docking experiments after entering orbit, which is the first step in China's space station program.Cui said the launch site has an updated computer center and command monitoring system and increased ability to adapt to changes in mission conditions, as well as the resources to handle both the launch and command duties. An integrated simulation training system for space launching has also been developed for the docking mission.The mission comes just one month after the Long March 2C rocket malfunctioned and failed to send an experimental satellite into orbit. The Tiangong-1 mission was subsequently rescheduled in order to allow engineers to sort out any problems that might occur during the launch.Cui said that engineers conducted a two-month comprehensive technical check on equipment at the launch site from March to May. The safety and reliability of all the instruments have been significantly improved."[The launch site] has the full conditions to conduct the Tiangong-1 mission," said Cui.The Tiangong-1 will remain in orbit for two years. During its mission, it will dock with China's Shenzhou-8, -9 and -10 spacecrafts.Unmanned docking procedures will be an essential step toward China achieving its goal of establishing a manned space station around 2020.

NANNING, Sept. 1 (Xinhua) -- In south China's Guangxi Zhuang Autonomous Region, an area renowned for its history of musical folklore, local residents have found a unique way to spread knowledge regarding AIDS prevention."All people unite to fight AIDS! AIDS will stay away if we are equipped with AIDS knowledge," state the lyrics of one song that was penned by local songwriters as part of a local anti-AIDS campaign."We asked eight local singers to write and record songs about the disease. We think this is an effective way for local people to acquire AIDS knowledge," said 55-year-old Huang Zhanghui, a resident of the village of Shantun. He said that the songs are played through loudspeakers in his village every evening.The songwriting campaign has been effective because folk songs are a traditional artform in the region, making them more readily understandable and acceptable for local residents, Huang said.Guangxi has been one of the hardest-hit areas in China in terms of the number of AIDS infections discovered there, ranking only after central China's Henan Province. More than 76 percent of the infections are sexually transmitted, according to Ge Xianmin, an official from the AIDS prevention office of the Guangxi regional government.Bama County, which administers Shantun, is known for the longevity of its residents. Nearly 2,500 of its residents are more than 80 years old, and another 81 have celebrated their 100th birthdays."We will not let AIDS threaten this tradition," Huang said.Huang was selected to be the head of the village's AIDS prevention office just two months ago. In addition to the creation of folk songs, the office spreads AIDS prevention knowledge through text messages and publicly screened films.
