I find it hard to believe that Popular Science would make such a mistake, but the author has reinforced the mistake by starting the article with “The dark side of the moon, despite its name, is a perfect vantage point for observing the universe.”
But all the quotes from scientists correctly say “far side of the moon”.
I know this isn’t really “science news” but I couldn’t find any other community to share this.

i think you may be a bit off base here
