Okay, so we're putting like a small pathfinder radio telescope called Lucy Knight on the lunar far side.
And really, it's a pathfinder.
It's the simplest thing you can imagine that can receive radio signals from the outer space.
So people have been dreaming about putting a radio telescope on the Moon because the Moon has a special property.
Then on the far side of the Moon, you at the same time shield it from the Earth and shield it from the Sun.
And that's supposed to make it one of the best
observatories for the radio frequency observations in the entire solar system.
And especially so at the very low frequencies, where basically observations from the ground are very, very difficult.
If you go below 50 megahertz, observations from the ground, basically it's like looking up from the bottom of the swimming pool.
Everything is blurred.
It's a total mess.
Yeah, it's a little project.
It's basically calling a telescope.
In some sense, it's a misnomer, right?
It has essentially four antennas, the four stick antennas like your portable radio.
It's really more kind of radio receiver.
It's like...
FM receiver we have at home, but kind of a slightly lower frequency and can kind of see all the frequencies at the same time.
So it will make very, very blurry pictures of the sky that we can then reconstruct to then turn into kind of like a low resolution map of how the sky looks like at these frequencies.
However, having said that, it will be the first time in the history of humanity we're actually able to make any maps at this very, very low frequency.
