中国将建造超越美望眼镜300倍的新一代哈珀 [英国媒体]

Is China building the next Hubble? Country reveals plans to build space telescope with field of view 300 times larger than Nasa's

中国将制造新一代哈珀？中国公布建造视野为美国哈珀望远镜300倍的太空望远镜的计划



China has plans to build a new space telescope that could outperform Hubble.

中国计划建造比哈珀更好的太空望远镜。

According to reports, the new telescope will be similar to Hubble, but will have a field of view that is 300 times larger.

据报道，新的太空望远镜将和哈珀类似，但是视野是哈珀的300倍。

It is expected to capture 40 per cent of space, with the same precision as Nasa's telescope, within ten years.

这款新的望远镜有望在10年时间内捕捉到40%的空间，而且精度和哈珀一样。

The new telescope, which has not been named yet, will have the ability to dock with China's modular space station, the Tiangong.

这款还没命名的望远镜将可以和中国的天宫太空站对接。

This means it will not face the same problems as the Hubble space telescope, which requires a shuttle mission to reach it any time it needs repair or maintenance.

这意味着它不存在哈珀望远镜所面临的问题，每当哈珀需要维修或者保养时都需要发射航天飞机进行维修保养。

As Hubble was built using repurposed reconnaissance technology, the military implications of this are obvious. China wants its competitors to know that it can see everything they're doing.

由于哈珀是利用侦查技术制造而成的，所以其军事意图相当明显。中国想让自己的对手知道别人做得到的事情他们也可以做到。

Plans and actually building it and getting it working are two different things.

计划与实际建造并投入运行是两回事。

Where did they get the Technology? Oh that is right from the USA / Britain / and the rest of the other advanced country's . Like every thing else they have pilfered.

他们的技术从哪里来的？哦，来自英美以及其他先进国家。就好比他们偷窃的所有其他东西一样。

Piggy -> Boli2222
From hacking Nasa computer.

通过入侵美国航天局计算机获取的。

That would reveal some very interesting pictures.

那肯定可以拍到一些非常有意思的照片。

China will launch it and declare all of space now belongs to them.

发射这个望远镜后，中国将宣称所有的空间都属于他们。

All stolen technology.

都是偷来的技术。

china has PLANS. america has the hardware, in place.

中国有计划。而美国已经实现了部署。

adrian -> usernamexx
I seem to recall a while back when America had plans and Russia had the hardware in place. Times change so don't be so sure you will always be on top.

我记得那时候美国只有计划，而苏联已经实现了部署。所以物换星移，不要以为你可以永远处于最顶端。

As much as little shots at China are fun, it's sad that they have more plans to look into space than we do. 

吐槽中国是有点意思，但是同样悲伤的是他们的太空计划比我们多。

Nice one, another organisation joining in to trying to understand the universe.

很好，又一个组织加入来更好的了解宇宙。

Trevor -> Just saying...
No, I think they will use it to understand our universe, i.e. spy on us.

不，我觉得他们会用这个来了解我们的世界，即监视我们。

Point it at earth and let's have a real photo for a change rather than all this CGI rubbish.

将其对准地球，然后拍一张真正的地球照片，而不是老是那种CGI垃圾图片。

I bet it's not as good as the James Webb Space Telescope (JWST)

我认为它没有韦伯太空望远镜好。

Comments - no substance and no technical details - just a "wish list". China has not yet pioneered any space development yet, simply repeated what the US and Russia/USSR have done previously. Their manned vehicle is based on Soyus - upgraded yes, but not original. And, before we get too excited - how long ago was Hubble designed and launched and China is saying "after 2020" for their telescope. Top marks to Chinas efforts be they are a long way behind established capabilities, let alone forging new ones. 

没有实质的东西也没有具体的技术细节，只是“希望”而已。中国还没有原创的空间探索，只是一味的重复美国和苏联/俄罗斯以前做过的事情。他们的载人飞行器是基于Soyus----虽然是升级版，但不是原创。哈珀的设计和发射是多久之前的事情了，而中国说其望远镜将是2020年后的事情。中国需要付出极大的努力，因为中国现在的技术远远落后于美国，更别提制造新的更好的望远镜了。

It will be good to compare pics.

用来对比照片还是不错的。

divingdong
My only fear is they will be pointing it art us on Earth to keep an eye on what we are doing.....

我唯一的担忧是他们会对准我们并监视我们的一举一动。

If the field of view is bigger the magnification will be smaller - so not necessarily better than Hubble

视野越大意味着放大率越小，所以未必会比哈珀更好。

John -> Taxed to death
Likely bigger and better sensors than Hubble's, increasing the field of view. The aperture is about the same as Hubble and that what limits resolution and effective magnification.

可能是传感器比哈珀的更大更好，从而提升视野。其光圈和哈珀的一样大，而限制分辨率和有效放大率的正是光圈大小。

GnosticBrian -> Taxed to death
John - The field of view is determined by the optical charcteristics of the telescope. Magnification depends on the focal length of the telescope and of the "eyepiece". For example, a 50mm eyepiece used on a telescope with a 1000mm focal length would yield a linear magnification of 20x (1000 / 50 = 20). A 5mm eyepiece used on the same telescope would yield a linear magnification of 200x (1000 / 5 = 200). Aperture would determine how bright the image was but NOT the magnification.

楼上的，视野是由望远镜的光学特性决定的。放大率取决于望远镜和目镜的焦距。举个例子，如果望远镜上的目镜是50毫米，焦距为1000毫米的话，那么获得的线性放大率则是20倍(1000/50=20)。而如果用的是5毫米的目镜，那么获得的线性放大率则是200倍（1000/5=200）。光圈决定的是照片有多亮，而不决定放大率。
