The world's largest radio telescope FAST activation of local tourism, does interfere with scientific monitoring? -Radio telescope, telescope-IT information
World's largest single 500-meter aperture spherical telescope (FAST) has been put into use.
Designed and developed by Chinese scientists, the construction of large scientific facilities, in addition to overseas media attention, for many ordinary people in the country, and FAST became their tourism coordinates.
September 27 to October 10, hosted by the National Astronomical Observatory of the Chinese Academy of Sciences building, from concept to site to completion, took 22 years to science also officially opened to tourism, load testing of the starting area.
FAST focus of local Government saw in tourism industry, stimulate local economic hope. However, the sensitivity of FAST radio telescope for radio, some scientists worry, let go after tourism, will affect the FAST listens for sounds of outer space.
World-class equipment and local economic development, how to balance FAST project management an important issue in the future.
Within a 3 km radius of the radio silence
FAST can "tune in" deep space objects by radio waves. And light, radio waves are electromagnetic radiation, but very long wavelengths, from about a mm to more than 100 kilometers. These signals travel furthest distance in space of the universe, and therefore very, very weak. For radio telescope aperture larger, more signals that can be received.
Therefore, as FAST as the Center, is within a 3 km radius of the radio silence, cannot be used for any machine that can produce waves, surging Han Jinlin National Astronomical Observatory of the Chinese Academy of Sciences researcher told the news (www.thepaper.CN).
"Within 3 km, use any electronic device to interfere with the accuracy of FAST. FAST is used to detect signals from the sky, compared to mobile phone signals and signals from the sky, a lot better, microwave ovens, mobile phones are unusable, even including the ignition of the car. "Surging Han Jinlin told the news.
In order to protect the FAST project, the local government issued a 500-meter aperture spherical radio telescope of the qiannan Buyei and Miao autonomous prefecture runs quiet region environmental protection law of electromagnetic waves, to provide for the setting in 5 km radius of the core zone is prohibited, use radio (stations), the building produces electromagnetic radiation facilities, which means that in the context will not be allowed to use mobile phones, TV, microwave oven, induction cooker, petrol vehicles.
Despite the promulgation of the regulations on the protection of, but Han Jinlin said in an interview that, although unable to use cell phone signals, if 10,000 visitors, 1 people bring cell phones into the radio silence, are likely to have an impact on FAST.
World-class equipment and local economic balance between
FAST project under construction, it has been the subject of attention, many people are hoping to see for yourself the pride of Chinese science. On September 25 after the FAST was officially put into use, the local governments are starting to take this project to build the tourism industry.
? Construction FAST radio telescope
Pingtang County official website describes, the County Tourism cultural industry park construction project for radio astronomy is mainly relying on large radio telescopes, build a set of tourist services, science education, leisure health and experience comprehensive tourism cultural industry Park. Park location close to Radio 5 km core area, covers an area of about 4500 acres, main building into the night sky astronomical elements 5 stars hotel Tian Yuan hotel, FAST Visitor Service Centre, astronomy experience.
The Guiyang evening news, 11 golden week starts on the first day, first day of national day Golden Week Ping tang of 78,500 tourists, an increase of 50.17%, tourism income of 57.33 million Yuan, an increase of 43.32%. Ping Tang China "eye in the sky" scenic spots include, FAST viewing platform, pingtang astronomical science cultural Park in two parts.
Up to now, the fears of crowd congestion brought mobile phone signal interference does not occur. FAST after the project is completed, the use of equipment is still managed by the National Astronomical Observatory of the Chinese Academy of Sciences, but scenic area planning and development organized by the local government. Surging News (www.thepaper.CN) from Pingtang County, qiannan Buyei and Miao autonomous prefecture, Guizhou province, area management Office found, before the tourists to visit the viewing platform, mobile phones and other electronic devices must be register and does not allow visitors to drive to, specified by the unity ride shuttle bus, in accordance with the lines running at a constant speed, drive about 40 minutes later.
Landscape test phase, to visit the observation deck personnel must carry out Internet reservation and registration, walk-in visitors will not be allowed to enter the protected area.
National Astronomical Observatory researchers, FAST (500 meter aperture spherical radio telescope), Assistant Project Manager, scientist, Peng Bo had said in a popular science lectures, if one day want to feel life without a mobile phone, you can travel to pingtang FAST, enjoy the "lost" State.
In his view, as FAST telescope site, pingtang in Guizhou province, is expected to become a high-end scientific tourism, stimulate local economic development.
FAST equipment users and understanding area developers, to make this science project maximum efficacy. How management can learn from the United States United States o Lei Xibo development of radio telescopes.
United States o Lei Xibo radio telescope rise and decline
In the FAST it is put into use before, Arecibo (Arecibo Observatory) is the world's largest single-aperture radio telescope. It is 305 m in diameter, later expanded to 350 meters, is located in Puerto Rico's Arecibo Valley, managed by Cornell University.

Arecibo Observatory officially opened on November 1, 1963, and since then, thousands of scientists use it, also welcomed numerous visitors.
In 1974, the United States Princeton University in New Jersey, Professor Taylor and Hulse discovered the first binary radio pulsar system PSR191316. Taylor Lei Xibo o use radio telescopes thousands of observation, access to the orbital period of the pulsar 20 years proved observations in accordance with results of general relativity, finally confirmed the existence of gravitational waves. Therefore, the two won the 1993 Nobel Prize in physics. This has become the pride of the Arecibo radio telescope.
In addition to scientific achievement, have just built the Arecibo telescope is also favored by Hollywood. The GoldenEye 007 series and film some of the scenes were shot in the area of the contact.
Data shows that every year to United States visitors Lei Xibo Observatory about 130,000 people, or at least brought more than $ 50 million for local income. Unfortunately, at present due to disrepair, lack of maintenance funds, this was the world's first radio telescope, now rusting.
全球最大射电望远镜FAST引爆当地旅游，是否干扰科学监测？ - 射电望远镜,望远镜 - IT资讯
全球最大单孔500米口径球面射电望远镜(FAST)已经正式投入使用。
这个由中国科学家设计、研发、建造的大型科学装置，除了受到海外媒体的关注外，对于许多国内的普通大众来说，FAST更是成了他们心目中的旅游坐标。
9月27日起至10月10日，这个由中科院国家天文台主持建设，从概念到选址再到建成，耗时22年的科学装置也正式对外开放旅游，开始景区的负荷测试。
FAST的关注度让当地政府看到了打造旅游产业，拉动地方经济的希望。不过，FAST射电望远镜对于电波的敏感度，让一些科学家担心，放开旅游后，会对FAST监听外太空的声音造成影响。
世界一流设备的使用和地方政府的经济发展之间，究竟如何平衡，成为FAST未来项目管理的重要议题。
半径3公里内的无线电静默区
FAST可以“收听”太空深处物体发出的无线电波。和光一样，无线电波也是一种电磁辐射，但是波长非常长，从大约一毫米到一百多公里。这些宇宙信号在太空中穿行遥远的距离，因此也非常、非常弱。对于射电望远镜来说口径越大，可接收的信号就越多。
因此，以FAST为中心，半径3公里内都是无线电的静默区，任何能产生电波的机器都不能使用，中国科学院国家天文台研究员韩金林告诉澎湃新闻（www.thepaper.cn）。
“在3公里内，任何电子设备的使用都对FAST的检测准确性造成干扰。FAST是用来检测外星空信号的，手机的信号与外星空信号相比，要强很多，会微波炉、手机等都是无法使用的，甚至包括汽车的发动机点火。”韩金林告诉澎湃新闻。
为了保护FAST项目，当地政府颁布了《黔南布依族苗族自治州500米口径球面射电望远镜电磁波宁静区运行环境保护条例》，规定在半径5公里的核心区内严禁设置、使用无线电台（站），严禁建设产生辐射电磁波的设施，这意味着在该范围内将不得使用手机、电视、微波炉、电磁炉、汽油车等。
尽管颁布了保护条例，但韩金林在采访中表示，虽然手机信号无法使用，若1万个游客中，有1人将手机带入无线电静默区，都有可能会对FAST产生影响。
世界一流设备和地方经济之间的平衡
FAST项目在建时就一直受到外界的关注，许多大众都希望能亲自看看这个中国科学领域里的骄傲。自9月25日FAST正式投入使用后，当地政府也开始借此项目打造旅游产业。
▲在建中的FAST射电望远镜
据平塘县官网介绍，该县射电天文科普旅游文化产业园建设项目主要是依托大射电天文望远镜，打造集旅游服务、科普教育、休闲养生、观光体验的综合旅游文化产业园。园区选址紧挨大射电5公里核心区，占地约4500亩，主要建筑有融入星空天文元素的5级大酒店星辰天缘大酒店、FAST游客服务中心、天文体验馆等。
《贵阳晚报》的消息，十一黄金周开始的第一天，黄金周第一天平塘接待游客7.85万人次，同比增长50.17%；旅游总收入5733万元，同比增长43.32%。平塘“中国天眼”景区包括，FAST观景台、平塘天文科学文化园两大部分。
截至目前，外界担心的人流拥挤带来的手机信号干扰并未发生。FAST项目建成后，设备的使用仍由中国科学院国家天文台管理，但景区的规划和开发由当地政府负责。澎湃新闻（www.thepaper.cn）从贵州省黔南布依族苗族自治州平塘县景区管理处了解到，游客到观景台参观前，必须将手机等电子设备寄存，同时不允许游客自行开车前往，需搭乘统一指定的摆渡车，按照规定的线路匀速行驶，驱车40分钟左右后到达。
在景区测试阶段，到观景台参观的人员必须进行网络预约和身份证登记，未预约的游客将不允许进入保护区。
国家天文台研究员、FAST(500米口径球面射电望远镜)工程副经理、科学家彭勃在此前的一次科普讲座中表示，如果有一天想感受没有手机的生活，就可以去平塘FAST旅游，享受“失联”的状态。
他认为，作为FAST望远镜台址的贵州平塘，有望成为一个高端的科普旅游地，拉动地方经济发展。
FAST设备的使用者和景区的开发者应该配合默契，才能让这个科学项目功效最大化。如何管理则可以借鉴美国美国阿雷西博射电望远镜的开发。
美国阿雷西博射电望远镜兴盛和衰落
在FAST正是投入使用前，阿雷西博天文台（Arecibo Observatory）是世界上最大的单面口径电波望远镜。它直径达305米，后扩建为350米，位于波多黎各的阿雷西博山谷中，由康奈尔大学管理。

阿雷西博观测站于1963年11月1日正式开幕，从那以后，有几千位科学家使用了它，也迎来了众多的参观者。
1974年，美国新泽西州普林斯顿大学教授泰勒和赫尔斯发现第一个射电脉冲双星系统PSR191316。泰勒利用阿雷西博射电望远镜进行上千次的观测，获得这颗脉冲星20年的轨道周期值，证明观测结果与广义相对论计算结果符合，终于证实了引力波的存在。因此，两人也一起荣获了1993年诺贝尔物理学奖。这也成为阿雷西博射电望远镜的骄傲。
除了科学成就外，刚建成的阿雷西博望远镜还受到好莱坞的青睐。007系列《黄金眼》和电影《接触》的部分场景是在这里拍摄的。
有数据显示，每年去美国阿雷西波天文台参观的游客约13万人，至少为当地带来5000万美元以上收入。可惜，目前由于年久失修，缺少维护经费，这座曾经世界第一的射电望远镜，如今已锈迹斑斑。
