You want to think bold? How about a Project Orion, using SRBs(shuttle reusable boosters) to loft it beyond the bulk of the atmosphere, maybe 15 km or so, putting it beyond any possibility of fallout. With 30 or so SRBs, we could place it at an altitude where we could cleanly put several thousands tons of payload, probably 7k+ into low earth orbit. That would mean we could place a moon colony with about 20 people that could extract h2o and nickle-iron at one of the lunar poles and that would open the whole solar system to us. The costs? A one, maybe two, time exception to the test ban treaty, negotiated with Russia who has expressed a willingness, and the will to do it. Based on the original Project Orion estimates, padding for inflation and the fact that the estimates were likely very optimistic, we could probably put 4k to 6k metric tons on the surface of the Moon for $20 billion or so. That would include a LEO space station with a tug that could move 20 or so people from low earth orbit to low lunar orbit, and a tug that could go from low lunar orbit to lunar surface, with a matching station. With the ability to mine lunar ice and iron-nickel from the regolith, we could build solar-powered satelites pretty cheaply. With that, we have essentially unlimited power available. Keywords. Solar powered satelites. Nuclear thermal rockets. Project Orion. URLs. neofuel.com http:/www.nuclearspace.com islandone.org We know how to build this stuff now. NERVA and Project Orion were researched decades ago. Things like the Nuclear Light Bulb, which could give us cheap and clean ground to low earth orbit given access to h2o in orbit, are more speculative. But low earth orbit to anywhere else is already established. With potentially a huge amount of power available for just a fraction of keeping the Iraqis in line it seems like a nobrainer. Except, of course, to those who are used to having no brain...
