High Launch Costs - Result of Physics?
John Ordover wrote: Here's a big clue for you John, the market and the production capacity developed side by side. As microprocessors became more popular the fixed production costs got amortized over larger numbers of parts, lowering the per part cost. Of course. But nothing in space is becoming more popular - in fact, comsats are -less- popular than they were. This is either simple ignorance or a somewhat strange way of twisting words around. Comsats are providing greater and greater deliverable bandwidth and communications circuits. The only way you can claim that comsats are less popular than they were is if you are either referring to the current investment market or have some figures indicating that the rate of increase is greater for terrestial communications. Do you have any references to back up your claim? Mike Walsh |

Walsh made the phosphor on my monitor glow in such a way as to indicate that: John Ordover wrote: Here's a big clue for you John, the market and the production capacity developed side by side.

Actually, for thousands of years, you could walk from England to the
US - how do you think the Native Americans got there? Did they start from England, or Europe for that matter? Notice I said "Massachusetts" not "North America." Eg, I was referring to the colonization in relatively recent history, not prehistory. You couldn't walk the Atlantic in 1621. You'd paddle over to the mainland of Europe (if you don't have boats of some kind, you can't be in England in the first place) If the Bering Strait was dry, wouldn't the Channel also have been? Colonization was practical because you could easily live off the land and in fact had natives to trade with. The natives were as likely in some places to attack you as trade with you. There was, as I said, food, water, and air. And your grandkids will have the knowhow to produce these from local resources on moon/Mars/Ceres (take your pick). It will be about as iffy as new-world colonizers in 1621. They also had problems of adapting to new survival conditions (as regarded climate and agriculture). |

At last I realize why we disagree on cost estimates for development of a space transport. You believe the Space Shuttle is a good data point; I believe it is an incredibly lousy data point from the economics point of view. In the context of what I was discussing when I made this particular comparison I believe the "baseline knowledge" I was referring to was the aerothermodynamic environment on re-entry of a winged body vehicle. I maintain that integrating the propellant tank results in a much more benign reentry environment as a result of much lower planform loading. The effects, IMO, tend to compound: lower temperatures yield lighter TPS and that leads to lower planform loading that leads to lower temperatures, etc. And as far as economics goes, it is a real data point. Got any others? No. But I'd rather consider the set of data to be empty --rather than a set containing only bad data points. The only other ones that can be used are capsules such as Mercury, Gemini, Apollo and Soyuz. Which we probably both agree aren't appropriate. The basic problem is that the only real data points are incredibly lousy from an economics point of view. However, if you re-read my post you should realize that wasn't what I was describing. OK. When it comes to Shuttle, my fuse is probably too short. My main observation is that our relative orientation with respect to acceptable data may explain the gap between us on cost estimates for what may be possible. That doesn't meen that you may not be right; moreover, you are entitled to your opinion with respect to what are reasonable cost estimates --the range of which are probably very unpredictable at this time. I just hope to be somewhat convincing that the low end of the range should not be dismissed as completely impossible.

What is likely is that this Ordover chap is some college undergraduate even further down the learning curve then I was when I jumped on this list when I was 16. He probably (almost definitely) misunderstood a few popular consumption articles about the financial woes of Iridium and Teledesic, and took it to mean all comsats, not understanding the difference between satellite phones for instance, and satellite TV, satellite radio, other forms of satellite communications, imaging satellites, etc. I'm guessing this because of his statement about how there aren't any applications that a satellite can do that a cell tower can't do for less. This may be partially true for one small niche market, but obviously false for many other markets (especially the earth observation markets). I think he's just a clueless fool who grabbed hold of one little piece of information and think it makes him wiser than anyone else. Unfortunately this is all too common these days. I guess the good news is that there are many people who aren't this way. ~Jon |

Fortunately, my newsserver seems to not pass along messages from AOL users. I think this is one of the more effective troll filters invented.

But I guess the important point is that we don't
need to prove anything to the Ordovers of the world. I am exactly the kind of person you have to convince if you want investors who would just as soon invest in cheese as space. You have to show the short-term profit return. You throw out terms like "infrastructure will be developed" that seem to assume that infrastruture will appear from nowhere, at no cost, by magic. The reality is that the infrastructure you describe is wildly expensive, and no one wants to pay to put it in place. |

I kinda look forward to the day sometime soon when we can put Ordover's
quotes up next to the "geniuses" that said that heavier than air flight, rocketry, and personal computers were either impossible or useless. You may have a very long wait. I've been waiting for Moon exploitation on some kind of grand scale since it was first suggested in 1969. Since then, we've done -nothing- to move that forward, and aren't doing so now. In the 70s we had a Mars lander and a space station. In the 21st Century we have a.... couple more Mars landers and a Space Station. No progress in -decades- toward exploiting the Moon. Again, what is the short-term, immediate payback that will interest private investment in the large space structures you suggest? Be more specific than "not as hard as Ordover thinks." What -exactly- is the profit making plan - 100% profit within five years - that you will wow investors with so they'll put up the money for the intermediate stages? Name one product of which we are short of on Earth that can be more cheaply made on the Moon, and sold at a great profit. |
