　　■ 亚洲最大射电望远镜今在上海天文台启动

　　■ 应用于明年探月工程

　　亚洲最大射电望远镜　高70米　重2600多吨　占地面积相当于8个篮球场大小　主反射面直径65米　可以全方位360度转动

　　东方网10月28日消息：据《东方早报》报道，它可以观测到100多亿光年外的天体，它可以清楚地听到来自宇宙深处微弱的射电信号，它可以精确跟踪高轨地球卫星、探月卫星和深空探测器，它就是亚洲最大的射电望远镜。

　　今天，这台高70米、重2600多吨、占地面积相当于8个篮球场大小的巨型射电望远镜将在上海天文台正式落成，这一台望远镜最重要的任务就是要在明年我国探月工程二期当中发挥它的作用。

　　何谓射电望远镜

　　直径越大“视力”越好

　　与直接成像的光学天文望远镜不同，射电天文望远镜的原理是用外形像碟状的天线，接收无线电波来确定航天器的位置和轨道。因此这个射电望远镜的直径越大，它的探测范围越远，也就是“视力”越好，擅长接收遥远天体发出的微弱电磁波信号。

　　这次安装在上海的这台射电望远镜主反射面直径是65米，相当于8个篮球场，可以全方位360度转动，它涵盖了射电天文研究的全部厘米波级和部分毫米波级的波段，同时配备高灵敏度接收机系统，目前从综合性能上在世界上应该是排名第四位的。

　　功能有哪些

　　听到宇宙深处微弱信号

　　射电天文望远镜建成以后，它可以清楚地听到来自宇宙深处微弱的射电信号，可以观测到100多亿光年以外的天体。

　　这台主反射面直径65米、全方位可转动的射电天文望远镜是由中科院、上海市政府和中国探月工程办公室共同出资建造的。它从2009年底奠基开始制造，历时两年，目前在上海松江佘山基地的中科院上海天文台已经基本组装完毕，10月28日将会进行首次启动。

　　这台天文望远镜建成以后，可在四个低波段频段投入工作，之后将致力于完成四个高频波段的接收设备以及主动面调整系统的测试。总之，望远镜系统全部建成后，将会在我国射电天文、地球动力学还有空间科学等多个领域发挥它的重要作用。

■ Asia's biggest radio telescope was launched today at the Shanghai Observatory

■ used in lunar exploration program next year

Asia's biggest radio telescope, 70 meters high and weighing more than 2.6 thousand tons covers an area equivalent to the size of the main reflector surface 65 meters in diameter can be 360 ​​degree rotation of eight basketball courts

LONDON October 28 news: According to the Oriental Morning Post reported, it can be observed celestial bodies of more than 100 million light-years away, it can clearly hear the faint radio signals from deep space, it can accurately track high orbit Earth satellite, lunar exploration satellite and deep-space probes, it is Asia's biggest radio telescope.

Today, this 70 meters high and weighs over 2.6 thousand tons, covers an area equivalent to the size of eight basketball courts of giant radio telescope was formally unveiled at the Shanghai Observatory, the telescope is the most important task next year, China's lunar exploration program. two to play its role.

What is a radio telescope

The larger the diameter of the "vision" the better

Unlike direct imaging optical telescope, a radio telescope principle looks like a dish antenna to receive radio waves to determine the location and orbit of the spacecraft. The larger the diameter radio telescope, its detection range farther is the "vision" for the better, good to receive distant faint electromagnetic signals emitted by celestial bodies.

This installation in Shanghai, the radio telescope main reflector surface diameter of 65 meters, the equivalent of eight basketball courts, and can rotate 360 ​​degrees, it covers all cm wave and part of the millimeter-wave level of the band of the radio astronomy research , equipped with a high-sensitivity receiver system, from the overall performance of the world should be ranked fourth.

What features are

Hear the weak signal of the depths of the universe

After the completion of the radio astronomy telescope, it can clearly hear the faint radio signals from the depths of the universe, celestial bodies observed more than 100 million light-years away.

The main reflector surface diameter of 65 meters, the full range of rotatable radio telescope is jointly funded by the Chinese Academy of Sciences, the Shanghai Municipal Government and China's lunar exploration project office construction. From the end of 2009, the foundation began manufacturing, which lasted two years in the Shanghai Songjiang Sheshan Ji ground, the Shanghai Astronomical Observatory, Chinese Academy of Sciences has been basically assembled, October 28, will start for the first time.

Telescope built in four low-band frequency range to work after will be committed to the completion of four high-frequency band of the receiving equipment and active surface to adjust the system test. In short, the telescope system are all completed in various fields of radio astronomy, geodynamics, there is space science will play an important role.

Would you mind to tell me from which TV report you got this image?

Thx,

Thx, just found it on Link

If my chinese is not wrong, the title is called "Force of China", or something like that?

great you have found it!

I will have it translated as "China's Efforts" - " Force" may sound a bit intimidating to the faint-hearted cheerleaders and unnecessarily adds to the billow of "China Threat" conspiracy theorists!

The program covers a wide spectrum of Chinese scientific efforts / discoveries developed or in the pipeline which ranges from archeology, pure physical researches. aerospace .... etc.. Hope you enjoy it!

This is the largest stationary radio telescope in the world。

China is indeed planning the world's largest movable radio telescope in Xinjiang，with the main reflection plane measuring 110m in diameter compared to the just-completed 65m telescope in Shanghai。 Its frequency of operation，at 100GHz，will also be higher than the Shanghai telescope‘s。

The development of the new YF-100 LOX-Kerosene rocket engine, for the futur CZ-5 rocket...

In some screens we can even see the mockup of YF-660, main core engine of the developing CZ-9 heavy rocket which could be used for manned lunar program.

are you elixir from forum-conquete-spatiale.fr?

love all the stuff you're posting over there. you shouldn't waste your time here..lol

Yes,it is me.

YF660 viewed from a different angle：

CZ(Long March)-9 is making nice progress!!!

 

[qwerrty]

wow, i thought it's only exists on paper..
no real funding yet, until they have some success with cz-5 first?

 

[hk299792458]

The project of CZ-9 has been officialized, it seems...

We can see the difference in terms of size between a CZ-5 and a CZ-9 -

And the configuration on the left, with new YF-660 LOX-Kerosene and new YF-220 LOX/LHX engines, had been choosen -
