/begin/ THE POLITICS OF SPACE COLONIZATION Sid Goldstein January 12, 2001 (notes by Chris Churchill; missing concluding remarks) * Life is fragile; it can be erased by global catastrophe. This could be self induced or astronomically induced. Presently (2001), we have no mechanism to deter or stop a near-Earth object (NEO). Meteor crater-like impacts happen about once every 100 years. * Comet Shoemaker-Levy 9 impacted Jupiter in 1994. Scars the size of Earth were observed * Conclusion: we are going to get hit by a NEO. What are we going to do about it? * Mass drivers are simple and economical on the Moon. There is no atmosphere and the gravity is weak. Costs of pound per launch for the Shuttle (STS) is high, about 10-50 thousand dollars per annum [actually dependent upon number of launches (= total operation costs / number of launches)]. * In space, we need matter to live off- raw materials. Getting it to space needs to be economical. Once it is in raw form in orbit, the material can be refined in space. The lunar regolith contains, oxygen, helium-3, water, and silicon. * Once material is mass driven to escape velocity, it can be funneled into an orbiting mass driver to send it to another location, even Earth orbit. * All this can even happen using asteroids, which have even lower masses! * Space colony technology will be directly applicable back on Earth. The unique challenges and resulting solutions will find there way back to Earth: agriculture, recycling, material science... * Space colonies can have all of the comforts of Earth and unique areas of zero- or micro-gravity. Recreation will especially be unique and it follows that healthful activities will be more varied and more commonly used. * All we need to do to make this so, is to make the decision to go. Natural course of events unfolding would probably take us 100+ years before we could be there, when we could decide to make it so in 20 years. * To make it so, we need to consider the whole picture. Including not wasting the hardware we use to get there! Skylab burned up 23 years ago when it fell from Earth orbit, which was happened because we had no desire/capability to boost it into a stable orbit. The shuttle uses an external tank that costs 100 million dollars. It is burned up and wasted for each mission. * We could use these external tanks as living space modules for a space station! We need to take risks, which the government is not willing to do. Only the commercial sector can do this effectively, but there is a catch-22. In short, our dependence on fossil fuels is the heart of the matter. [insert "The Problem" chart] * Usage of fossil fuels, a finite resource upon which we depend, creates an unstable economic system. Inflation, stagflation, high interest rates... and this is due to insider short sided, and selfishness because power is in the hands of so few, i.e. it is nearly impossible to research and develop new technologies because the power structure can control the flow of capital and is interested in the status-quo. * The above is the catch-22. The research and development of new technologies are not funded by the elites who control the capital. * We went to the moon in less than 10 years - a decision that was made when we had neither the infrastructure nor technology to go there. We did it. Then we stopped. Why? Politics. The popular support was not there and much that support was eroded away by the media. The media remained critical of the costs of manned space flights. * Challenger 1986. Why did it explode? Not because of engineering but due to politics. First, the decision to launch was political. But most of all, the design of the launch vehicle is flawed. Solid rockets are not safe; they cannot be turned off nor their thrust regulated. Liquid fuel, which is more expensive, was decided against because of its high cost. This was a political decision. * The commercialism of space is unlimited. Consider the benefits to humanity due to the computer industry. Communication satellites are an excellent example. To make commercialism possible, we need to develop better space transportation technology. We need to bring down the cost of putting objects into orbit. The government, however, must seed the process to break the catch-22. * The future of manned space is also unlimited. Again, we have the technology to create a space faring civilization; we just need to develop it. The hard part of getting the entire solar system at our finger tips it low earth orbit (LEO). This is the most expensive step as things stand now. Once we break this barrier, we then need to develop an infrastructure, or transportation system, that can be used time and time again. * In conclusion: (sorry folks, didn't get it down) Sid could provide? /end/
