Hi, my name is Joe. I'm from the U.S. and my question is should we go to the moon? I think that we absolutely should go to the moon because we need to find new places to live for the people who are going to be around in like 500 years, and the moon's one step for us to find those places. I also think it's really interesting to learn that there once was water on the moon. So, I'm really interested in that kind of scientific news, at the same time it's hard to justify how much money it costs to explore space and to explore the moon when we have so many practical problems on earth.
