I really wish the people downvoting me would go read a book and not rely on Buzzfeed listicles of top 10 cool things we did on the moon and other crap pulled up via a five second Google search.

If you aren't old enough to remember, go ask someone who was. If you can't find one, then do some actual reading, or check out any of the thousands of documentaries out there. (That doesn't include the History Channel's Nazi Moonbase conspiracy theories.)
