Eli5 why can’t telescopes see landing zones on the moon?

482 views

I was gonna prove to my co-worker we did in fact land on the moon, but Looking up how to see the landing sites with a telescope said it is physically impossible (improbable). An explanation went with it but… Yeah… It’s why I’m here.

I know we have a lunar satellite that can show it, but I’m prepaid for inevitable ” computer graphics recording”

Edit. Maybe I’ll just ask for someone to explain “Dawes limit”

There’s an easier way to do it than looking with a telescope, because NASA literally planned to have a way to easily confirm it and do experiments by figuring out the distance to the moon and having a way to reflect back.

They placed essentially a series of 5 mirrors on the moon by different missions, you can shoot light/laser at any of them and it reflects back. The use of mirrors and reflections is standard stuff in astronomy and optics. Astronomers do use these reflectors too!

To actually see the landing sites, you’d need a huge telescope with a lot of fancy equipment on the ground, or more likely, one in space. The moon is far and seeing that good of resolution on a tiny thing like a landing site youd need an enormous telescope. Telescopes are great for seeing big objects, but when you need to see small, and far away, the size necessary to do that becomes much much bigger
