Which is the furthest side for us.

And if you continue the quote:

until humans were able to send spacecraft around the Moon, this area had never been seen.

Which implies that in terms of it being "unknown" saying the dark side is no longer relevant.

I was an engineer at NASA on the lunar lander program. The engineers I worked with were deeply involved in analyzing how the lighting conditions impacted the navigational dispersions during the landing approach.

Every one of those guys would have understood what someone colloquially means by “dark side of the moon”. There are other, more precise, terms for the unlit side.

Popular science is not really a science journal, it’s an entertainment publication. I don’t see an issue here.

We're talking about science here, which is a field where precise definitions matter.

Thankfully, everyone in the scientific conversations around the moon know exactly what the Dark side of the moon is.

My favorite thing about science and scientists is when they can put their egos aside, admit that they misunderstood something when they spoke up, and say "Hey, I didn't quite understand that, but now I do" instead of doubling down on their mistakes
