I've have a long essay in this quarter's issue of The New Atlantis, in
which I discuss the myths of the old space age. http://www.thenewatlantis.com/archive/6/simberg.htm |

... I've have a long essay in this quarter's issue of The New Atlantis, in which I discuss the myths of the old space age. http://www.thenewatlantis.com/archive/6/simberg.htm Nice, though one point I do question is your emphasis on reusability. Is this not picking winners? Can the market not decide this for itself? I suppose the suborbital tourist market tends to imply reusability, though there are other initial markets where reusability may not be so optimal. Personally I favour an even greater emphasis on flight rate and open organic type grass roots competition. Within the current limited market size, (which will not suddenly grow by many orders of magnitude overnight), it would be nice to be able to facilitate a smaller vehicle size. One which might sustain considerably higher launch rates even while starting from the current existing small market, though growing sustainably with it over time. Even now I see the Falcon development path leading on to the Falcon five. Where does launcher growth end? Space X is being sucked into the old ways. Given the opportunity, everyone seems to opt for bigger vehicles instead of higher flight rates. The existing launcher paradigm has created the existing market paradigm which is corrupting new launch initiatives back into the old launcher paradigm, it is a vicious circle. To break out of this I am wondering if on orbit assembly is actually the critical first step to high flight rates, and thereby CATS. Launcher growth prevents high flight rates. I suspect CATS might only grow from a market that discourages launcher growth. Pete. |

It's obviously too short for him to go into specifics (e.g. graphs showing the per flight cost of different types of designs as a function of flight rate). Instead, we have the tired old analogy of comparing space flight with air travel. Everyone has their own take on the specifics of this analogy and how this analogy really applies to space. Rand concentrates on flight rate, not on technology. This makes some sense as the technology in air travel has changed dramatically over time (from piston engines on wooden, cloth covered, open air bodies to high bypass turbofan jet engines bolted to pressurized bodies made of aluminum alloy and composites. In other words, air travel has long been a very active, profitable, industry, long before today's technologically mature passenger jet aircraft came into being.

Is this not picking winners? Yes. Can the market not decide this for itself? Sure, but my opinion is that we won't get costs low enough for tourists if we throw the vehicle away. If we don't get them low enough for tourists, we won't get them low enough to open up space (or have an "affordable" and "sustainable" VSE). To break out of this I am wondering if on orbit assembly is actually the critical first step to high flight rates, and thereby CATS. It may be, for orbital launchers. Launcher growth prevents high flight rates. I suspect CATS might only grow from a market that discourages launcher growth. That may be the case, which is another reason I oppose heavy lift. |

Another problem is with his call for abrogation of the 1967 Outer Space Treaty...one loopy sidelight of that would be that a country's airspace could continue up into outer space (this has already been somewhat done with the comsat positioning spaces in GEO.) and in theory you would need a country's permission to have your satellite pass over it, or the country it was passing over would have the right to destroy it. That was one of the early legal concerns that space law faced back in the late 50's; by letting Sputnik fly over the U.S. unopposed, the U.S. set a legal precedent that would pay big dividends when the era of the reconnaissance satellites arrived, as was pointed out in the book "The Heavens And The Earth". Rand's idea seems to be to let the government set financial rewards for individuals and corporations to develop private spaceflight into a workable form- if we are going to go with a nice free-market approach, then let's free the private side of the equation from the threat of _all_ government interference....by having it do whatever it wants to do all on its own.

Flannery made the phosphor on my monitor glow in such a way as to indicate that: Another problem is with his call for abrogation of the 1967 Outer Space Treaty Not abrogation--withdrawal or renegotiation. ...one loopy sidelight of that would be that a country's airspace could continue up into outer space No, as you say, overflight was accepted in 1957. If the OST was needed to resolve this issue, how did we manage for a decade without it? And even if it were a problem, it could be handled in the renegotiation.

I was digging around on Fortean Times breaking news and ran into this: http://www.stuff.co.nz/stuff/0,2106,3028490a11,00.html It appears that the Maori have gotten an early foot into the space ownership concept. :-D Rand's idea seems to be to let the government set financial rewards for individuals and corporations to develop private spaceflight into a workable form- if we are going to go with a nice free-market approach, then let's free the private side of the equation from the threat of _all_ government interference....by having it do whatever it wants to do all on its own. What's your point? To prevent the danger of creeping socialism ;-) , it would be best if business were to develop any private spaceflight capability by its own means, rather than an influx of public money...Burt Rutan made a spaceship on his own, Bill Gates could certainly develop a privately financed space access capability if he thought it was a good idea (hell, Gates could probably finance his own manned Mars expedition if he felt like it.), but I have doubts about the concept that we will develop this new technology of large-scale space access, and then it will develop into a worthwhile and profitable industry all on its own. About the only thing that might have a near-term economic impact that can be done in LEO over the next ten or twenty years would be large scale solar power satellites. The amount of weight that would have to carried to orbit to build those would require large, not small, carrier vehicles of the type you seem to favor... or are the Moon and Mars in the scenario you propose?

While you may think that SS1 is the greatest thing in the history of mankind based on your "opinion". SS1 is no way comparable to a Gemini either in technical capability or achievement. It most certainly can not be compared in anyway to the pioneering achievement of Alan Shephard and the American Space Program et al. I also note that you make the assumption that reusable vehicles are the way to go based on your opinions. Please be aware that these things can be mathematically evaluated much more closely, and as such there is no need for your uninformed opinions on the matter. The same can be said for your opinion poll reference especially when Market Analysis contradicts your statemetns. It's a shame you didnt take the time to actually research the subject before writing a bunch or personal opinion fradulantly passed off as an analysis. But then again, that would have made much of your statement a bnuch or horse hockey. |

I would agree, but there's no chance of public money not being involved in spaceflight, politics being what they are. I'm just attempting to divert it in a useful direction. About the only thing that might have a near-term economic impact that can be done in LEO over the next ten or twenty years would be large scale solar power satellites. Nonsense. We don't even know if SPS is economically feasible, and if it is, it's not likely done in LEO. As I said in my article, there is only one large-scale market for which the payloads are already built, and don't require other technological breakthroughs. |
