When (at what year), do you think there will be a turning point in space explorations, where people routinely fly into Earth’s orbit, fly to the moon and beyond. Everything has a turning point, from having computers the size of a room, to the small laptops we have today. That’s just one of the turning points in human technologies, that took about 40 years. What about space, when will that significant change, that will ease and expand space travel forever come? And also, since time dilation is possible, which means that it’s possible to “travel to the future”,but not to the past, so if you go to the future from your current point, lets say 40 years into the future, from your point of view, it will be a turning point, because the technology and the rest of the things will be more advance, and since you skipped 40 years, it will be a sudden turning point for you. So why can’t there be a “sudden” turning point in technology today, or right now? Why is everything seem to progress that slowly over our lifetime, why can’t it progress faster, just as if you skip 40 years to the future, that’ll be a sudden turning for you. I think I found an answer. The ‘turning point’ will be when we develop an inexpensive and reliable method of accessing space. With chemical rockets it costs about $10,000 for each pound placed in Low Earth Orbit. That alone makes sending things into space a loosing proposition. Additionally rockets have a tendency to fail, and when they fail, the fail catastrophically (remember Challenger and Columbia). Until the cost and reliability issues can be over come true manned space travel will remain a dream. Another factor is learning how to successfully exploit space resources. I would think that everyone who is concerned about global warming, the environment, dwindling global resources, over population or conservation would be hard core space enthusiasts, but they are not. I’magine moving all our ‘dirty’ industries into space, beaming inexpensive solar power to Earth and turning the Earth into a giant park. These are not pipe dreams. The Earth is finite, the resources of space are limitless. Before that can occur, we need a reliable and relativity inexpensive means to get into space. Building a space elevator would be a start. The technological challenges are great, and the first one would not be cheap. These ideas are being seriously considered in Japan. This is not science fiction. Once the first space elevator is constructed (I am going to say within 20 years), the solar system will be ours. The real question is; do we have the will to do it?
