Patience dear boy, it’s not even arrived yet….
Anyway, they'll be in the infra-red, so you wont be able to see them... whistle

A lot of its work will be to do with matters WAY beyond our own galaxy.

It’s utterly inspiring that thousands of members of the same species from numerous nations can collaborate to produce days like today, yet the same species can also give us Bojo and Trump.

Shouldn’t scientists be running all our institutions?

Some footage of the gold coating being applied to one of the mirror elements:

Each of the 18 mirror elements are 1.32 meters (4.3 feet) in diameter, flat to flat. They weigh about 20kg each.

As one, the answer is maybe.

I think the core of your suggestion is right though… but rather than inject scientists into all of our institutions, many of them could do with an injection of science into their approach. Science isn’t a big pile of facts, it’s a process and an approach to learning and to solving problems.

Certainly there should be more scientists as MPs. In 2015 only 30 or so (from 600+) had science degrees.

Aren’t the people responsible for putting this wonderful object there engineers, not scientists?

I guess a lot are but they’re just doing what the scientists ask.

There is an overlap between scientists and engineers in that sort of academic environment. There are a lot of specialisms, people interested in a particular area and devote their studies to covering both the theoretical and practical aspects of the technology. The teams involve a real cross section of skills from the purely theoretically minded to the hands-on practical types.
Something like this would not be possible without all of them providing the experience and expertise of their particular field.

Isn't that true of all life. The best work and best achievements are the result of co-operation between people with a range of talents and experiences.

Saying that scientists should run everything is not very clever. However, I agree wholeheartedly that there should be better understanding and knowledge of science in places of power and influence.

I know some scientists who would be hard pushed to navigate a shopping trolley around a supermarket.

That's still several months away - a great deal of commissioning and calibration work is needed first
Interesting,

Have to get the detectors all cooled for a start.

I guess there is probably a certain amount of degassing/out gassing from all of the components that will also happen. I imagine quite a lot of care is taken to make sure nothing is deposited in the pathlength of the instrument or detectors.

Also got to get the tripod all set up level and polar align the telescope too I suppose.

I assumed this would all be automated seeing its in space...
