Building the Giant Magellan Telescope

[@Raptorman0909]

This was an amazing presentation -- this project manager gave more details on telescope design than I've seen anywhere else and that's not his primary function. Simply amazing!

i guess Im randomly asking but does any of you know of a method to get back into an instagram account? I was dumb forgot the password. I love any help you can offer me!

[@zapfanzapfan]

A very thorough presentation. I really enjoyed all the tiny engineering details, those are often left out of other presentations. I guess it is a race against EELT for first light :-)

An excellent presentation. Thank you Dr. Franson.

[@A-Milkdromeda-Laniakea-Hominid]

Wow they had a schedule according to pre-pandemic best-case lol. It's almost 2022, they should have the enclosure completed and the telescope delivered, with the first primary mirror up in a few months time... I wonder where they really at. Fascinating instrument, looking forward to seeing it completed!

[@1958SSG]

Great accomplishment Dr. Fanson. I recently visited Gemini in Chile and that was impressive to me so I can imagine what this project meas for all of us. Amazing!

[@denispol79]

I wonder how they will change the central mirror for recoating.

[@Norman92151]

Very informative. Odd that Newton the actual inventor of the reflecting telescope was never even mentioned. His tiny little reflector was the progenitor to this monster.

Absolutely amazing. I can’t wait

Really a superb talk! Such an exciting project.

[@davidaylsworth8964]

Outstanding presentation!

I can't wait to see the results of all these telescopes. I imagine it must be hard working on them for 20 years.

[@tobiaspiechowiak5432]

Why hard? What do you mean?

[@podboq2]

I wanted to stand up and cheer at 45:16 deleting the atmosphere for the sake of astronomy, through the power of silica and electromagnetism awesome :)

[@Nine-Signs]

I hope with this new gen of telescopes, plus Hubble replacement, that we will be able to image exoplanets with some clarity. The first world clearly seen beyond our solar system, would be a magnificent achievement.

[@marianneoelund2940]

Even at the distance to our closest neighboring star, the Airy disc diameter projects to an object 400,000Km in diameter, so no, there will be no clear imaging of any exoplanets.

"The larger the telescope, the larger the D." Ain't that the truth.

[@johnnymatias3027]

So there might be an 80m telescope in 40 years, and if the same rule applies to space telescopes there would be a 13m telescope in space in 40 years, but really with falling launch costs we might be able to get a larger one up there sooner.

[@UnitSe7en]

"The larger the telescope, the larger the 'd'" So, it's the inverse rule of sportscar ownership.

[@WillArtie]

HA! Nice comment. Even had to tell my wife about your comment, as I new she would enjoy it. Which she did. BTW - I own a very small and beat-up Toyota hatch-back.

[@bigtymer586]

Power plants have been floating FD and ID fan bearings on high pressure oil films for 30 years.

[@infocat13]

Have there been studies of building two long lead items for TWO telescopes but not an assembly of the second telescope until a later date? & I am a citizen project management policy wonk :)

[@jwarmstrong]

Why build 2 at less than 2x the cost when waiting will mean 3x or 4x spending on the second one - unless managers are thinking James Webb project at 5x & still not launched...

[@Wtfinc]

why circle mirrors?

[@khuyennguyen23]

to collect lights

[@louisbarbisan8471]

Why circled mirror! The reason is that the 4 corners are very hard to figure and polish, yes it would be a much larger light gathering bucket.

[@jrdeckard3317]

Since the mirrors aren't touching, the computer must interpret what light is doing that falls between the mirrors. How do they know the computer is telling the truth?

[@nadahere]

All telescopes will be displaced by our low cost [$5MM], compact telescope with a broad field magnification from 10X to continent discernability at 100 light year distance. Similar performance on the obverse side with table top sized microscopes where even the interior of the nucleus will be viewable. Path to atomic scale electronics manufacturing with real time defect removal for perfect outcomes each and every time..

[@StagnantMizu]

wtf u talking about

[@krzysztofb5830]

Nice presentation, but I don't know what's going on with the pupil of the human eye. By my calculations, the Yerks refractor collects over 40,000 times more light than the human eye. The Large Binocular Telescope with an area of ​​1,110,000 cm^2 would collect 5,500,000 times more light than the human eye, but the GMT is supposed to collect 50 million times more light than the human eye and it comes out to 19 million. The ELT is supposed to collect 100 million times more light and only gets about 50 million. A telescope with a diameter of 100 m would have a light-collecting surface of 78,540,000 cm^2, which means that the calculations would result in less than 400,000,000 times more light than the human eye, but the GMT and ELT calculations that I made myself do not match the data provided on the websites. these telescopes.

[@gazzaboo8461]

Hah, filmed in Keckistan I see. May the Kek be with you!

[@nelsonjr2521]

EACH PRIMARY MIRROR WORKS AS A SINGLE TELESCOPE AND THEN THEY FORM A UNIQUE IMAGE FROM DE 7 PRIMARY MIRRORS OR THEY ARE POLISHED TO FORM A SURFACE LIKE A UNIQUE MIRROR WITH ABOUT 24 METERS.....???

[@aquasurfer9]

I would think that at that altitude, it makes sense to power everything with solar and lithium batteries such as the tesla wallpacks. Generators with fuel would not only be noisy but you have to get the oil out of the ground or undersea, refine it, then drag it up the mountain to power some generator which will have fumes that will accumulate on those expensive mirrors. Living in San Jose, I used to wash my window every morning due to a film from fossil fuel burning.

[@kristoferstoll587]

First Light is now slated for 2029! WHAT HAPPENED!

[@flowinsounds]

shame about the hit at DC, followed by 'stay on the high road'. otherwise, what an interesting and amazing project

Don't be so sensitive...he's allowed to speak the truth

[@lindsayk41]

By the time it's done it'll be obsolete

[@tobiaspiechowiak5432]

Don't think so. Where should the competition come from?

[@ronaldgreene5733]

. . the "fact" of expansion needs only consensus as the true "confirmation" . . versus the scientific method -- an ideal that no longer exists in practical terms as money and the politics of science in today's environment take precedence without acknowledgment but managed through funding and requisites for assignment to any role.
