It seems to me there's free market capitalism flourishing in the European Economic Union, as well as along the Pacific Rim. I think there may be other entities besides the U.S. that could benefit from private space industry. There are some multi-national corporations that strengthen the economy of several nations. For example CFM International is both U.S. and French. Would they be able to compete for both U.S. incentives and European prizes? Hop http://clowder.net/hop/index.html |

Find a solid gold asteroid...then you'll have the killer app. Space transportation would leap a century into the future. But, unless China makes plans to plant a flag on Mars, there's not much out there other than the public imagination to give manned spaceflight a purpose. And that's mainly driven by romantic musings of the Apollo program. |

Find a solid gold asteroid...then you'll have the killer app. Space transportation would leap a century into the future. Or not. The problem with relying on "valuable minerals" is that the market can glut; the world produces some 2500 tonnes of gold a year. A 10m diameter gold asteroid would have about four years worth of that production; it scales up from there. IANAEconomist (I mean, I can do sums g), but you get the idea... that'd do really weird things to the market. The oceans contain some $1.5 *quadrillion* worth of gold (or so my slighlty hyperbolic-looking source says; this number seems inherently WAG); about ten million tonnes, or four thousand years of production. I'm not drawing an explict analogy, just making a point; "valuable" resources are really only valuable should it be possible to make a profit on them. No-one's made a profit evaporating seawater to get it... If there's an economic reason, it won't (I suspect) be precious metal in the Belt, or the discovery of diamonds on Enceladus, or the like... -- -Andrew Gray |

I understand there are asteroids rich in metals, metals not bound up in oxygen, sulfur etc. like the ores we can get at at the top of earth's crust. Wouldn't delta V expense make even a solid gold asteroid unprofitable? Hop http://clowder.net/hop/index.html |

... Wouldn't delta V expense make even a solid gold asteroid unprofitable? Delta V does not cost money. It costs energy. Which in turn cost close to nothing in dollars. The issue lies designing a space vehicle with maximum deltaV per buck. Nobody has tried that yet. All sorts of rockets have been optimized for maximum ISP, minimum GLOW and what not. Nobody has tried to optimize for deltaV per dollar. -kert |

Manned spaceflight should
be an national industry not a government program. Craig Fink Where's the revenue stream that would interest industry? The technology for establishing, say, a Moon base, has existed for -decades- and is well within the technological capacity of industry. That it hasn't been done is entirely because no one can think of a way to make a buck at it. If your best idea is to send people on joyrides, you're not going to motivate industry. |

There have been a multitude of reports on the huge store of energy in the deep sea methane hydrate deposits, with returns as large as the biggest oil fields, but it's too hard to get to and nobody with any money will bother to exploit it. What makes space any different? IMHO: I'm afraid that space is useless as a source of product or services. Jim Davis |

By the time you get to it you'll haveve spent a good portion of it. By the time you haul back a few thousand tons to Earth and safely land it you'll have spent most of the rest of it. By the time you get paid for the gold you brought back word of the gold's arrival will have flattened the gold market... and you'll be broke. Industrial materials in space will stay in space to be used in space by folks who work in space. And that's what a gold asteroid would become... gold foil, gold conductors etc. The only exception would be materials that are _only_ produced or procured offworld... that are wanted on Earth. -- Chuck Stewart "Anime-style catgirls: Threat?

Better to concentrate on replacing the shuttles lift capacity in an open market. For each of the three people the shuttles leave at the station it is also leaving about 4 tons of thrust, equipment and supplies. That according to some estimates is 50 tons a year add to that launching NASA's space plane and you have a market for 10-70 flights a year on commercial launchers depending on size. We do not need any new technology just what we have used more efficiently and often. |
