What Comes After LUVOIR? Three Extreme Ideas For Space Telescopes

Ғылым және технология

While we’re all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved.
(Please get approved, please get approved.)
We’re going to need a way to pass the time. So let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes.
Unless you’ve been crawling through scientific journals like me, I guarantee you’ve never heard of any of them. But when I’m done, you’re going to want to fund all of them.

    My reason to live: I found this video to be so emotionally charging, both with hope and depression. I am an elder now and the excitement of the almost daily discoveries in physics and astronomy is the primary thing that makes the realities of aging, such as chronic pain and decreasing senses, bearable. In other words, they are literally keeping me alive. So I strive to live another year, to watch the Web telescope's launch, and will be more emotionally involved on that day than any sports fan ever - rooting for its success and deeply fearing any glitch. And now... this wonderful video of future telescopes that, unless there is a miracle breakthrough in the biological or the android sciences, I will have to watch from the Other Side, which I know won't hold the excitement of moment by moment temporal involvement. Oh well, this is still the most interesting time in human history to be alive and we are very lucky to witness it. So I'll quit my sniveling : )

    Well, @@sebastianmalcolm8771, saying this is 'the most interesting time in human history' doesn't signal optimism, but opportunity. I think the current new generation will be the last of mankind as we have known it. If we don't start working together to solve climate change we'll likely become pre-human with millions of displaced people needing to be exterminated to prevent being over run. That's hardly human. I'm rooting for Artificial Intelligence, which if done right could usher in an age similar to Gene Roddenberry's Utopian vision, Star Trek, and the Post-Human. Machine super intelligence could create the abundance through solving the riddles in physics eliminating fear and making greed obsolete, puting an end to the wastes of war and the famines they cause. Racism could become only a fading, slightly embarrassing memory. Biological and cybernetic advances that could allow some of the young folks alive today to be virtually immortal, if they choose. With toiling like a slave at a spirit numbing job to subsist is replaced by computer and robot created abundance granting us the absolute freedom to pursue our personal happiness and be whatever we chose - artist, dreamer, explorer, etc. And all watched over by machines of loving grace : )

    My favorite would be a 500 million km optical interferometer, but the technical challenges are formidable, so better to start small with a few kilometers aperture. Telescopes on the moon also have an enemy in the form of electrostatically charged dust. Perhaps mounting them high enough would help, but in any case would perform far better than anything on Earth.

Although not quite 500 million km, it's still a 10 million km virtual lens diameter (distance between L4 and L5 LaGrange points).

Maybe we will have the technology with LISA and then the Big Bang Observer to sync multiple spacecraft to less than a tenth of a wavelength. I think L2 is most likely. The earth is too thermally instable and the atmospheric effects over larger distances are too different to sync these signals. L4 or L5 would be too far away and therefore unnecessary comlicated.

    I think both optical and radio telescopes on the far side of the Moon make a lot of sense, because they would be static, making interferometry easier. Something like the descent stage of the LM or Blue Origin’s lander could be used to land telescopes on the Moon. It would need elaborate fold out solar panels, and batteries to power it through the two week lunar night, and an orbiting relay satellite to get the data back to Earth. The last topic of your video on the large flotilla of very small telescopes also makes a lot of sense.

    I agree, for most cases. I think lunar material, like regolith, can supply raw material, but from most practical engineering angles, orbiting in free space is the better option. Especially if you want to really scale it up. In the near term smaller observatories may be reasonable, and easy to approve, as they would have the ability to observe earth (space force $$). Radio telescopes can take advantage of shadowing on the far side, and radio antennae are more electronic than optical. But for ground breaking size, orbit in free space has the advantages.

    How would Nautilius increase resolution if it were not an interferometer (signals not synced)? Also, why not make a space telescope interferometer as big as the span between the L4 and L5 LaGrange points of Earth if only the signals need syncing? Theoretically, that would need only 1 telescope at each LaGrange point, 2 in total, though 6 is preferred to rule out random noise from cosmic rays.

    Heres another idea based on gravitational lensing. James Webb will have a circular orbit around the L2 point. (How, I dont know, since there's no physical object there, but that's beside the point) The point is, Webb will be following a curved path imparted by some force. Now, it's pretty handy that the space that Webb is orbiting is empty, yet can cause a physical object to follow a curved path. It should affect light in the same way. Meaning gravitational lensing must be occurring. How strongly, I don't know... But here's the plan: at the L2 location, use lasers to create a grid, and use super accurate clocks to map out the deformation of that laser light in the L2 space. Once you know how L2 bends space, turn off the lasers and apply your knowledge of the gravitational deformation to gathered starlight. Computers would then be used to computationally "bend" the starlight that has been gathered into an image. I will likely be dead before they can build this (assuming the idea is workable), so they can name it after me or my pseudonym, Sparkleface.

    Hi Fraser. Using any lenses in telescopes instead of mirrors, doesn’t matter how sophisticated they are, is a bad idea. You know it. Because of the refraction itself. The bigger the lenses the bigger the problem of diffraction. The only way to use lenses is using filters that allow using only one particular wavelength and adjusting focal distance for this wavelength.

    The arrays would be the most realistic projects as they allow to build and position a lot of small units built-in series rather than a single massive module or building. A dense array of many 8+ m mirrors on the Lunar surface would be easier to set up than a single 100 m mirror (like a very large VLT or a whole array of Giant Magellan Telescopes ideally set up in a permanently shaded polar crater).

Astronomy is perfect as a trail blazer as it's a big ticket item ideally manufactured in space away from Earth's pesky gravity well. I was impressed by all these speculative projects. One day we'll look back and say incredulously 'they used to make that stuff on Earth, Seriously! Were they insane?'

    I always find it hard to get excited about projects, that haven't even a green light to build it. Even some telescopes that have a go are and were in real trouble (TMT, JWST). As for projects I hope that interferometry (direct, indirect) gets way better (cheaper, easier installation and usage, less light loss, longer baselines). And there is some work going into that direction. Fewer mirrors more quantum-thingies and glass fiber. Then, super cheap, lightweight, 3d printed mirrors would be great. And a lot of projects would benefit from it - Colossus telescope would be only one of them. And somehow I'm really rooting for the CTA-South and north. The science behind this is just mind-bogglingly fascinating. It seems to make so much sense to look further in to the terrascope concept. I would have no regret at all to skip Luvoir, if it would actually move those three things forward.

Get a few of those built and operational, then Starship can Tug-boat those to the destination, detach, then land it's load, all the while keeping a command presence in orbit, and mitigating the radiation and low g concerns with a proper Space Station...
