I would be happier seeing people living on the moon than more unmanned trips to mars. I would be even happier to see an orbiting space hotel than a few people on the moon. My point is I want to go to space. I'm not as concerned with mile stones for the human race at this point. We know we can send a probe to the outer reaches of the solar system. What we don't know is how to build safe efficient public transportation to the moon. That should be the foundation we work on and all other miles stones will follow. Space exploration should be pyramid shaped with more people closer to earth and less further away, not linear with one astronaut getting to each planet every 30 years. That is just political and doesn't really help the bulk of people. Our goal is to be able to live in space right? Somewhere I think that has gotten lost.
