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.

BEIJING, July 3 (Xinhuanet) -- The Atlantis mission to be launched by NASA on July 8 will not be an end to the space age, as some media suggest.Although it is the final mission of the space shuttle, it will open up "the next chapter" in the United States' space exploration, NASA's administrator Charles Bolden Jr said at the National Press Club in Washington on Friday."When I hear people say - or listen to media reports - that the final shuttle flight marks the end of US human space flight, I have to say . . . these folks must be living on another planet," he said."As a former astronaut and the current NASA administrator, I'm here to tell you that American leadership in space will continue for at least the next half-century because we have laid the foundation for success - and for NASA, failure is not an option," he said.NASA administrator Charles Bolden Jr drew a lot of media attention during his speech at the National Press Club in Washington DC.One of the foundations is the "unprecedented" research capabilities the International Space Station (ISS) now possesses, largely thanks to the space shuttle missions.Although some media imply that "the game will be up" once the ISS is out of orbit in 2020, he said the splendid research results and rich knowledge astronauts and scientists have accumulated through more than 1,200 experiments since 1998 have laid out "a stepping-stone to the rest of the solar system and the tip of what comes next".As NASA turns a new page, it will "focus on deep space exploration", while leaving US private companies to operate low Earth orbit transportation systems for tourism and business, he said.NASA will develop "a deep space crew vehicle and an evolvable heavy-lift rocket," he said. The moon, asteroids and Mars will be the next destinations for humans to live and work, he said."We will maintain and grow US leadership in space and derive all the benefits that flow from it. Tomorrow's space program is taking shape right now," he said.

SANTO DOMINGO, Aug. 19 (Xinhua) -- The number of deaths caused by cholera in the Dominican Republic have increased to 109, and there are 15,876 suspect cases, according to government figures released on Friday.Public Health Ministry said in a statement that the intensity of the outbreak has been decreasing since six weeks ago, but the region of Gran Santo Domingo, which includes the Dominican capital city, still faces a serious epidemic situation.The government is developing preventive measures which include informing the population, careful observation of diarrhea cases, providing drinkable water and building new public toilets as part of efforts to contain the outbreak, it added.The latest Cholera outbreak appeared in the Dominican Republic last November, a month after cases were reported in Haiti.The Ministry said they stepped up efforts to monitor the situation after tropical storm "Emily" passed through parts of the country two weeks ago.After the beginning of the rain season, cholera cases have increased generally and all the public hospitals in the country are provided with supplies and medical staff to care for the people with symptoms of cholera or other tropical diseases.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard's tablet TouchPad has become the hottest consumer electronics device on Monday after HP launched a fire sale for the discontinued product line over the weekend."It was like a stampede and they went quick," a Best Buy employee in San Diego told technology news website Betanews, describing the line waiting to buy TouchPad. He said the discontinued tablet was sold out five minutes after the store opened.The device is also getting snatched up at a lighting speed online and increasingly difficult to find.The TouchPad is no longer listed on Bestbuy.com in the United States, which last week was reportedly sitting on 270,000 unsold TouchPads and was hoping HP would buy them back.On Amazon, TouchPad tops the world's largest online retailer's electronics sales list, beating out the electronic reader Kindle and iPod touch.Last Thursday, HP announced that it will completely shut down its webOS operations, specifically the TouchPad tablet and webOS phones.The 16 GB TouchPad currently is only 99.99 U.S. dollars, compared to the original price of 399 dollars. The 32 GB model, which used to be 485.99 dollars, is now priced at 149.99 dollars.
