Spyware is constantly trying to improve upon resolution constraints; Raytheon have been funding quite a bit of it. But as our Nancy Grace Roman telescope shows, what is designed for spying on people can be repurposed to spy upon other stars and dwarf-planets. Today we're discussing the Rayleigh criterion. The minimum resolvable angle is proportional [1.22] to the wavelength (λ) over the diameter (D) of the aperture of a monolithic telescope.
Or: tyranny of the aperture limit
.
They want their multitude of 'scopes to be pushed into orbit or the Lunar farside or, most-likely, some SpL2. In space it's presently constrained by the Starship (D = 9 m), which compares with the Chilean 8.5 m mirror-'scopes.
In 2023, Stephen Fleming with Amit Kumar Jha and some others presented a telescope which might obviate the "monolithic" side of that, kind of like putting rockets in series to boost thrust. Last year they got their idea published.
They want to image other worlds without having to go there. We want to go to the Uranian moons and Triton again, so the project isn't for them. It might however be of use to get some better imaging of the KBOs, and Sedna.
They are teasing this for other systems. In that case they think they can remove the starlight from the array of images, without blocking the star in the 'scope itself (like with the Coronagraph). I expect the prime targets will be the Proxima and Trappist worlds.
The (smaller, cheaper) mirrors in space will have to stay at 20 meters, or whatever, from each other. So - pack poles? A better idea is to give Beyond Reach something to do.
