spacester,<br /><br />One of my biggest weaknesses is forgeting that what I was taught in school is often wrong. I have an odd fascination with science, and causality was a major part of my world view as I was growing up. The process of linear thinking, also known as rational thought, became something like a religion to me, and I denied all the intuitive, non-lienear aspects of my own existance. So, when I view a process such as space exploration, I tend to think that it should happen in linear fashion. Because, to me, space exploration right now is like building a bridge, a bridge between Earth and the rest of the Cosmos. We have not yet mastered traveling back and forth through the barrier that seperates us from the rest of everything, and to do so, making the journey cheap and safe, will be like building a bridge across a chasm.<br /><br />To my mind, building the bridge means giving those who are going to pay for it, one way or another, an idea of where the bridge goes, so that they will be willing to support our work. Private spaceflight ventures are using the same resource that the government uses, money, our money. Whether it comes from the personal wealth made from doing business with us or the taxes on the business we do, it is our money. If we don't spend enough of it on building the bridge, the bridge keeps falling down. We can show people the Moon, and say "that is where the bridge will go for now. Later, we will go other places, those little lights in the sky." Once the bridge is built, getting to the places on the other side of the barrier will be much easier, and much cheaper. But building the bridge will not be cheap, no matter how we go about it, because of the nature of the barrier. It has taken huge investments just to learn how to cross the barrier, and it still is very exprensive. I applaud those who are trying to learn how to cross that barrier on their own, but I want to make sure that their efforts do not interfere with the buildin <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>
