Welcome, Albert!

I totally disagree with you on the manned vs. robot issue, by the way. Yes, it's clever, and yes, machines are great, but there's nothing like a real person stepping on a new world for the first time to inspire us. Remember, the whole rest of the Universe that isn't Earth, is Outer Space. I'd hate to think we'll spend our entire future single-planet-bound, it's a very depressing thought.
