LOS ANGELES, July 5 (Xinhua) -- NASA's Juno spacecraft is 30 days away before its first launch window opens, the Jet Propulsion Laboratory (JPL) announced on Tuesday."One month from today, our first launch window opens at 11:34 a. m. EDT (8:34 a.m. PDT) and lasts 69 minutes," said Jan Chodas, Juno project manager from NASA's JPL in Pasadena, Los Angeles."Our primary launch period is 22 days long, and so if weather or other issues come up on Aug. 5, we have 21 more days to get Juno flying. Once we get Juno into space, it's a five-year cruise to Jupiter.""The launch window is the length of time allotted every day for an attempt to launch the spacecraft," said Chodas. "The launch period is the period of time in days when everything is in the right place to get your mission off to the right start."For a mission like Juno, getting everything in the right place includes considering the size of the rocket and spacecraft, where our home planet -- and in particular Juno's launch pad -- is pointed at any moment, and its location in space relative to other celestial objects like Juno's final target, Jupiter.Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from pad 41-C at the Cape Canaveral Air Force Station, Florida.The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska. Lockheed Martin Space Systems, Denver, built the spacecraft.

TAMPA, the United States, June 18 (Xinhua) -- The HIV/AIDS patients in the U.S. state of Florida are in dispute with state authorities over a proposal to impose tighter restrictions on those who qualify for drugs provided by the state's AIDS Drug Assistance Program (ADAP).According to the proposed restrictions, individuals would have to earn less than 21,000 U.S. dollars annually to qualify for ADAP drugs. If approved by the Florida Department of Health (FDH), this would affect approximately 1,150 HIV/AIDS patients."The FDH is currently looking at the number of cost containment activities, including altering the financial eligibility for ADAP services," said FDH's press secretary Jessica Hammonds. "After soliciting public input on this matter, the department is in the final stages of evaluating the matter."The Florida ADAP program serves almost 9,500 clients, each of whom receiving 8,600 dollars in funding annually, Hammonds said. There are still another 3,482 on a waiting list.Four FDH sponsored public hearings were held in April and May on the proposal to reduce HIV/AIDS funding. Two were held in Miami, one in Tampa, and the other one was held in the state capital city of Tallahassee. Over 1,000 people attended the hearings.The issue has become so ubiquitous that it caught the attention of the Elton John AIDS Foundation (EJAF), created by the popular entertainer of the same name.

coastline in the U.S. State of California sampled by the state water board harbored fish with mercury in such high concentrations that they shouldn't be eaten by young women and children, a newly released survey has found.Fourteen percent of locations had similarly elevated levels of PCBs, according to the survey published by The Los Angeles Times on Sunday.The most elevated concentrations of mercury and PCBs were found in San Francisco Bay and San Diego Bay, said the survey funded by the state water board.The findings, part of a two-year inquiry that is the largest statewide survey of contaminants in sport fish along the California coast, examined more than 2,000 fish from three dozen species gathered in 2009 from waters near Los Angeles, San Francisco and San Diego, the paper said.The survey highlights the health problem of lingering mercury, a poisonous metal that is found in fish globally, and of PCBs, toxic chemicals the United States banned in the 1970s, the report said.Both substances continue to pose a risk to people who eat fish caught along the California coast because they can lead to nervous system damage and developmental problems in children and can cause cancer, liver damage and reproductive harm, the report quoted researchers as saying."Unfortunately, we're not seeing many areas that are totally clean," said Jay Davis, a senior scientist for the San Francisco Estuary Institute and lead author of the study. But a catalog of where and in what fish the substances abound should help anglers make better choices, Davis said. "With good information, people can reduce their exposure significantly."Sharks had some of the highest levels of mercury because of their unusual tendency to accumulate contaminants in their flesh, while chub mackerel had the lowest levels of contamination, according to the survey.The survey results were used in part to help craft new fish consumption guidelines issued earlier this week for anglers in San Francisco Bay, the first update there by state health officials in 17 years. The advisory identifies shiner perch and other surf perches as unsafe to eat in any quantity and warns young women and children not to eat white sturgeon, striped bass and sharks caught in the bay, The Times said.The buildup of metals and other chemicals in fish is such a problem along the Southern California coast that health officials two years ago expanded the number of fish species on the "do not eat" list from one to five because of high levels of PCBs, mercury and the banned pesticide DDT, the report noted.

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.
