NASA does not have enough funding to do both Mars and the Moon. This is why you see many corporate players in the space industry these days. Politics will decide where we send probes or carry out manned missions, and those politics will now be driven by corporate interest. We are no longer in a continental race so to speak for space exploration. If NASA is to shift focus to a manned missions to the moon, then they wasted billions of dollars during the Obama administration for deep space projects beyond the moon. If you can't comprehend that, well, you aren't as smart and knowledgeable as you think you are.
