It makes me wonder, "Why?". Why bother going back to the moon? Unless they thought there was something to gain. Russia and China both received some of the materials that we brought back. Was this just a display of capability?
If so, is this all they were capable of? Why not go for some of the more unexplored regions, like the asteroid belt?
Even if this was a prelude to a manned moon mission, why bother going back? They should be reaching further and higher.
