The Square Kilometre Array (SKA)
The Square Kilometre Array (SKA) project is an international collaboration to build the world’s largest radio telescope. The SKA aims to conduct groundbreaking science that will transform our understanding of the Universe and of the laws of fundamental physics. The SKA will monitor the sky in unprecedented detail and map it hundreds of times faster than any current facility.
The SKA will not be a single telescope but a collection of telescopes called an array, working together over long distances – tens to hundreds of kilometres and eventually thousands of kilometres. The SKA’s construction has been divided into two phases: Phase 1 in Australia for SKA1-Low and South Africa for SKA1-Mid; and Phase 2 for SKA2 expanding further in Australia and South Africa as well as into other African countries. Scientific operations are scheduled to begin in the early 2020s.
When we get our "glasses" on, we should look for large exo-moon transits (watch the earth long enough from any angle and our moon would transit the earth) of inner rocky water-world exo-planets that are shielded by large, outer gas giants, but that are not so far in that tidal-locking will have taken place.

James Webb Space Telescope launches next year. It promises to have as big an impact on us as the Hubble did, has and does.
Plus I don't see why they would need to place such a platform on the surface of the moon. Why not just float them out in space in orbit with the moon and earth, to create a "baseline" using parallax of breathtaking distance and "magnification" and reception.
When a planet passes in front of a star, the starlight passes through the planet's atmosphere. If, for example, the planet has sodium in its atmosphere, the spectrum of the star, added to that of the planet, will have what we call an "absorption line" in the place in the spectra where would expect to see sodium (see graphic below). This is because different elements and molecules absorb light at characteristic energies; and this is how we know where in a spectrum we might expect to see the signature of sodium (or methane or water) if it is present.

...the satellite buster sends the millons of beams all over the galaxy at a very high rate so if something is out there it will uderstand the code and send it back .

Maybe they need a stable platform, I'm not a space scientist, but I don't understand why they can't be positioned with precision while floating in space.
I also don't understand why a radio telescope can't be unfurled in space to make each one just massive.
I don't know why we don't have all kinds of stuff on the moon by now.
China thinks they're going there and will be the first to operate on the moon..
