So, firstly, the far side of the Moon is what we call the dark side of the Moon, but it's not dark, it just when it rotates this far side of the Moon is facing towards the Earth but we are facing away from it. So we never see the far side of the Moon but it does get sunlight. But because it's always essentially pointing away, for the most part, from the Earth, it means it's a radio quiet place, it's the quietest place, we think, in the nearby universe because the loudest place in the nearby universe is the Earth. And the other side of the Moon, the side of the Moon that we see, is blocking it. So one of the ambitions is to test is this a great place to put radio facilities, because there are projects that have been designed to put a large radio telescope on the far side of the Moon. So the Moon acts as this giant, big shield. Now, for communicating data that means you can do ultralow frequencies, which is actually more efficient for transmitting data. Anything related to radio astronomy, understanding the gas in our Milky Way, all the way to the first stars, we always want the most radio quiet place. That's why Australia has always been an expert in radio astronomy. The only better place pretty much is not on this Earth, it's the back side of the Moon.
