Perhaps, you should stop being critical of the orbiter and prepare for your own cost-overruns in the DC-program. I'm very skeptical of the projections made by the DC-program.

Intelsat didn't "snub" the shuttle; Ronald Reagan kicked them off it. The Intelsat 6 birds were designed for shuttle launch as one alternative. They were among the losers when commercial payloads were thrown off the shuttle after Challenger. Nor would Intelsat have grieved for very long if NASA had refused the rescue mission (or asked them to pay full price for it). They have launch failures now and then; they're prepared for it. The rescue was useful, but far from vital. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Mon, 24 May 1993 23:16:51 GMT From: "Carlos G.

I agree that free space is a better environment for industry. However, I don't think that the leap in technology is the best choice at this time. A lunar base might be. The scenario you hint at above requires the development of new technology and techniques in a lot more areas than a Lunar base would. Extraction and processing of minerals from an asteroid requires completely different techniques, and will undoubtedly face many unexpected problems. On the moon, you can use (modified) existing techniques. >+ The technology and facilities developed with a lunar base project would >+ greatly reduce the cost of developing open-space projects.

They probably would. I can imagine improvements in small pumps and other things associated with heat transfer. Techniques developed for turning lunar dust into shielding and structural elements should be useful, if not directly applicable to orbital structures. The handling of dust in a vacuum is probably going to be troublesome, gravity or no gravity. > Most of the processes would be totally different because of the gravity > well and differences in ores. That's in favour of building a lunar base first. You can apply a number of known techniques, rather than having to develop _everything_ all at once. A lunar mine can use draglines, hoppers, etc, with some modification from off-the-shelf designs. You can make buildings using good old concrete and steel construction. :) A zero-g mine is going to be a risky project; not something you want to base the success of _the_ major space development (the first one is critical). > Long term recycling in a closed environment, and teleoperation could both > be developed just as easily in open space as on Luna.

Only a UN treaty is stopping them. Sure, the profits are high and the costs of developing the technology is much lower than that required for mining asteroids. Much of the technology is already proven (in cold Arctic winters). Besides, are those companies itching to develop those oil fields now, or are they itching to stake claims for future exploitation? :-/ > No doubt the Moon has many old rocks, some at least as old as the last > major bombardment, but comets and asteroids are likely the home of even > older solar system materials, not just rocks. Asteroids hold valuable information about pre-planetary formation materials and conditions. The moon holds valuable information about the planetary formation process, which the asteroids can't provide.

The pressure increases more gradually, and the interior isn't as hot.

Are they doing that today? No? Perhaps they're waiting until there's some infrastructure first. Inexpensive transfer vehicles and resources might make the difference for a corporate proposal. Some near-Earth space economic activity (such as a Lunar base) would provide some markets for such things as volatiles from asteroids. The mere existence of a major space project reduces the risk of further projects. I get the impression that it is difficult to get funding/approval for a project that is totally new and unproven. Private investors might be more likely to invest in a space manufacturing station if there were people regularly working in orbit, and there were supplies and services in place for them to use. > For scientific and public interest, the only other body with evidence of > open water having moved on it's surface in recent geological time holds the > highest interest.

Those are definitely interesting, but they'd be a lot more practical to investigate if there was some infrastructure in place. How about a nice long-term plan for space exploration and development? I suggest: Lunar resource extraction base (to provide Al & O2, and to develop vacuum and transfer vehicle technology) Space stations (to develop zero-g experience/technology, and a market for space resources) Near-Earth asteroid exploration/exploitation (to gain access to more resources, such as carbon and water) Mars exploration I'd sprinkle small scientific missions through there as funding allows. Al-O boosters and radio/laser receivers on/around Luna could cut the cost of planetary probes. If exploitation of the near-Earth asteroids was successful, and markets for space resources were developed (ie. some space stations), then the exploration and exploitation of other asteroids, comets, and planetary bodies might be carried out by private companies. They're just waiting for someone else to take the first big risk, and "break the path". :) > A lunar base would be a mammoth undertaking. A cometary mining program > would be similarly large.

No, I see the Lunar resource extraction project as significantly cheaper than a cometary resource extraction project (don't forget transportation of resources), and one that provides a useful return, if not a profit. BTW, is water and hydrocarbons so much more valuable than O2, metals, and silicates? You need those metals and silicates for the construction of structures to hold people who will buy your volatiles. :) Profit is for private companies; government's responsibility is to provide infrastructure and other support. Even if the Luna project is unprofitable, the return from the projects that become feasible due to its resources and existence could provide a good return on the investment. -- Nick_Janow@mindlink.bc.ca ------------------------------ Date: 25 May 93 00:47:36 GMT From: Gopinath Kuduvalli Subject: Moon Base Newsgroups: sci.space It seems to me there would be plenty of commercial opportunities if routine travel to and from the moon could be established.

However, if the goal is the development of space, including industry and long-term communities, then it may make economic and political sense.

Who's the customer for the exploitation? Companies don't do exploration unless they think there is a reasonable chance of profiting from it in the long run. Precise definitions of "reasonable chance" and "long run" depend on the amounts of money involved... and the price tags attached to NASA-style exploration (the only type with a track record) are so ghastly that any rational company will want to see committed customers (willing to pay high prices) before sinking any money into this.
