NASA plans to turn a moon crater into a giant telescope

Among grants given out for space projects by NASA, one project plans to put a radio telescope on the moon. The Lunar Crater Radio Telescope project aims to put a 3,281 foot (1 km) in diameter, radio telescope within a crater on the far side of the moon. Researchers think they could observe the Universe in more detail and it could offer a glimpse of some of the earliest moments after the big bang

It's a gigantic radio telescope, no glass or anything like that. I'm curious as to how much interference it would experience from lunar regolith accumulating on it over time, and how they would clean it... Also kind of curious why NASA isn't doing this as an array in space. Isaac Arthur has talked about using lunar craters for gigantic telescopes as well, using liquid mercury spinning in a crater to reflect the light. And gigantic arrays of telescope satellites covering hundreds of miles in volume in space, combining the image sort of like how the Hubble telescope does. Cool stuff is possible outside of Earth.
