NASA’s James Webb space telescope has been fully assembled
- Thread starter Forerunner
- Start date
Probably a silly comparison but after seeing that video this made me think a project this delicate is likely to be our lifetime's equivalent of the Contact rings in terms of "don't fuck it up"-ness and potentially setting our progress back by decades if it does mess up somewhere along the line. Something tells me there isn't a second one hiding somewhere either :p
Imaging technology has made MASSIVE leaps since the last major (Hubble Level) space telescope, can't wait!!!
All the issues they've had with this thing, I expect the rocket to explode before it makes it past the launch tower.
lol no far from that... a planet is not bright, so its impossible to capture the closest one are in alpha centauri system, 4,367 light years away

No. In theory the Terrascope could, but that's only if it works and they try it. The Terrascope would use the Earth's atmosphere was a lens. You could easily make out other planets and their topography.
Well, you could with high contrast imaging techniques. Even then you need planets to be very massive and as far as Neptune's orbit from its star. And all you get are pixel dots.

Yep, that's the dream, topographical shots of extrasolar planets is the next big step in astronomy.
Strange how I've been hearing about this amazing piece of engineering being built for what seems like nearly half my adult life and its finally done. We're finally at the home stretch. Only a couple more years to go.
It scares the hell out of me how easily even the tiniest problem could fuck up the entire thing. I suspect it will launch successfully, it's just that, once it's fully operational, there's literally nothing we can do to fix it, if something should go wrong.
We just have to hope that it gets meaningful data while it's fully functional.

I actually saw the guy's youtube video on this and I'm glad it is gaining traction. Only one way to find out is to try it and apparently it is much, much cheaper to boot. Hopefully he gets a NASA grant soon.No. In theory the Terrascope could, but that's only if it works and they try it. The Terrascope would use the Earth's atmosphere was a lens.

Seems like a cool dude. His example is how you use youtube to do actual good.
yeah watching the videos on this thing, so many moving parts. It's the tyranny of the payload, unfortunately.
Not really, but it will be able to tell us a lot more than we currently can know about them.
They fixed a giant physical flaw in hubble's mirror with software that (reductively) translated the data from the flawed element back to normal.
I more meant that it can't be physically repaired, unlike the Hubble.
It feels like it's taking forever to launch this thing. Been following this telescope for years and the date always feels so far away. Can't wait! Very excited for this.

This is some Asimov level madness. In the article it sounds like he's suggesting that the idea of using gravity as a lens is a possibility? Using the Sun as a magnifying glass would be an ironic role reversal. It's people like these that make me realise I am dumb as shit.
Yeah but it's possible some physical issues could be fixed with unexpected remote tricks

In his video and paper he explains it a lot more clearly. There is quite a bit of merit to it. This idea has been around for sometime, but it was originally proposed for the Sun. However using the Sun has quite a bit of problems and would probably not work with current tech. However, his idea is actually feasible, if it works.
I made a thread about it a few weeks back with more information about it.
we have our timeline so its going to fail, we arent getting a single image.
and Trump is gonna blame "Obama scientists" on Twitter.
you all know im right.

I reaaaally hope everything works out for this telescope so it can replace its big bro and provide us with all new types of images. It's super exciting.
All sorts of things have gone wrong with space probes and telescopes after they've been launched and fixes have been found from the ground.
The Fourier Transform was adopted for deconvolution of images taken with flawed lenses after the Hubble Space Telescope was launched with a significant aberration that interfered with its ability to focus properly on stellar objects. Which not only let them continue to take images with the Hubble while they planned a mission to replace the lens, but is used in many aspects of microscopy, particularly in biology imaging.
