The wiki also mentions that it was sometimes called the dark side because it was unknown to people, a complete mystery, until we send people and probes to it. It implies that since we have seen it calling it the "dark side of the moon" is no longer relevant.
My issue here is that the term "dark side" by meaning is the side facing away from the sun.
We're talking about science here, which is a field where precise definitions matter.
I see this as no different than the debate between "poisonous" and "venomous". In basic language terms the terms are interchangeable, but biologists use the terms to mean very specific things, and are not interchangeable.
It's because in science the little differences matter. And in an article talking about an upcoming project involving a specific area of the moon, referring to it as "the dark side" is incorrect.
