There is no "dark side" of the Moon that is unseen. The night side shifts around the Moon every month. We see it as a New Moon. To talk about the "dark side" when you really mean to say the "far side" is the signal mark of someone who is quite ignorant of astronomy. (The Moon could hardly be flat if the terminator spreads around as a curved arc.)
And what is so difficult about getting to the far side of the Moon? There are indeed technical difficulties, but nothing that has stopped anyone who is willing to solve the problems.
