Historical comparisons
Obviously historical comparisons have their weaknesses, but with that
caveat, what does the commercial passenger space industry look like to you? More like the begining of the airline industry, or more like the development of the supersonic aircraft by the US,Europe and Russia in the 60's and 70's? Obviously one industry turned out fairly sucessful while the other died a slow lingering death. Or perhaps you think a totally differant historical scenario is appropriate, or none at all. Thoughts? |

I don't really think the experience of zero gravity is going to drive a great wave of expansion. The reality is that space is just an inhospitable enviornment for human beings. It will never make a lot of economic sense to bring too many humans there; this given the fact that humans will be outperformed by thier technological creations sometime in the next half century. Of course, I could imagine machine intelligence bringing some humans to populate a terraformed Mars as a kind of humorous experiment... like a 22nd century TV show. What are the humans doing today, 35RE3? ...Look at that kid ride his rover! Personally I'm rather partial to the idea of populating the galaxy with various levels of intelligence, including unmodified human intelligence. This makes no economic sense, but it would have the merit of being a lot of fun. We could populate Europa with mermaids (just kidding). |

Obviously one industry turned out fairly sucessful while the other died a slow lingering death. Or perhaps you think a totally differant historical scenario is appropriate, or none at all. Thoughts? There are similarities to the beginning of the commercial air transportation industry - but differences. There is an apparent market for adventurous people who might have to decide between scaling Mount Everest or getting their (commercial? tourist?) astronaut wings. But there will apparently be few space passenger firms, and when airlines started there were many companies in many countries. Many of them started with surplus military aircraft. What is going to be the result of the first accident or two? The world is so less tolerant of error now. There are going to be no surplus spacecraft (on the market). My guess is that the market will slowly accelerate (so to speak) but that they will make it. The trip into space will certainly take less time away from your primary pursuits than will an ascent of Mount Everest or similar adventure travel. The market will not be motivated by the old Cold War competition, it will be a commercial competition. But it is going to take some time for the companies to break even. Certainly Paul Allen will not get his money back - he seems to have made a massive donation to get the industry started. I hope he gets to fly in space a couple of times - just to reward him.

Obviously one industry turned out fairly sucessful while the other died a slow lingering death. Or perhaps you think a totally differant historical scenario is appropriate, or none at all. Thoughts? Asked "What do you think about the American Revolution", Vietnamese general Giap said "It's too soon to tell.". The aerospace movement is one seamless continuum. Nature doesn't see the distinctions you portray. There was no moment that dinosaurs became birds -- they became ever more birdlike and ever less dinolike until what you see is birds but no dinosaurs. People observing birds flew kites, then made man-carrying kites, then engine powered kites. There was no moment when man transcended kites to airplanes. Kites became more planelike and less kitelike, although there are plenty of flying powered kites still today, and unpowered manlifting kites as well still seen in the skies. Catapults threw rocks, then flaming objects, then bombs. Flaming objects became self-propelled and catapulted themselves. Fireworks and pyrotechnics used gunpowder to push themselves, then push objects like bullets and cannonballs. The fireworks and pyrotechnics didn't turn into guns and cannons, they still exist every 4th of July. Jets and rockets came into existence due to expansion, not displacement of their predecessors. Jets and rockets are only really different in that one is air-breathing and the other carries it's oxidizer. Jets, cruise missles and ballistic rockets were all developed at once, while cloth-covered wooden planes still flew, and cloth-covered wooden planes still fly. The expansion of diversity does not require extinction of the earlier. Crocadillians and sharks watched the dinosaurs come and then watched them go. There is no commercial passenger space industry but every person who ever got their astronaut/cosmonaut wings has been a space tourist. Space is a harsh, demanding, unforgiving environment. There never has been a time when non-working travellers were welcome there and there isn't any prospects that they will be welcomed soon, if ever. There may never be a time when human deadweight is welcome in space. If you have nothing to contribute while in orbital space then there aren't any good reasons to lift you there. Sub-orbital joyrides of 15 minutes is another diversification, not a displacement of anything. It is not appropriate to even call it "commercial passenger space industry". It is doubtful that sub-orbital jaunts will become more orbital-like and less amusment-park ride-like. SSTO requires a rethinking that is more fundamental than any of the plans posted in public to date. None of these can morph into the kind of orbital docking and re-entry vehicles that will provide the ladder to the planets and stars. If anything they are money sponges sucking dry the funding sources and a distraction from what will work. |

Space capable rockets can double as strategic weapons systems. That's
because any rocket system that can place a payload in orbit around the Earth, can also place that payload reliably on any point ON the Earth. Also, tthe same technology that makes lightweight space reactors, and nuclear rockets possible also allows the construction of nuclear weapons systems. So, any space faring technology is also simultaneously capable of building WMDs and delivering them to any point on planet Earth. We live in an era where missile proliferation is controlled along with controls on nuclear weapons and nuclear material processing technologies. This need to contain iknowledge, information and skills hurts the natural development of space faring technologies by business. One outcome of this control regime is the adoption by governments of cost-plus contracting for space launch systems. This virtually guarantees that commercial space systems will be subsidized and gives the government ultimate control over these systems. This is a good thing if all you want to do is contain the proliferation of missile technologies. So, if we desire the commercialization of space travel we must first change the control paradigm and methods for missile and nuclear technologies. We would also do well to allow the ownership of space based assets and resources by people and business. Once these changes are in place I believe industry will discover what they must do in order to make commercial use of interplanetary resources and assets. Generally speaking what they must do is invest in rocket propulsion technology to reduce the cost of imparting momentum to payloads. With an exponential decrease in the cost of momentum achieved by business we will see vast changes in what we do in space. Since the Earth's surface bears a nearly fixed momentum relation to other pointsin the solar system, we can even predict the broad outline of development possible. 1) small suborbital payloads - ICBMs 2) small orbting payloads - satellites 3) large cislunar payloads - manned spaceflight And we've stopped there. But we can see, 4) very large interplanetary payloads and beyond that, we traverse this arc again, but at far lower costs, 5) privately owned suborbital ballistic travel 6) spaceship in every garage 7) space homes orbiting the Earth 8) interplanetary space homes Since the bulk of humanity will reside on Earth until steps 6 and beyond, the development of space faring technologies by commercial entities will result in a range of global services. These include; 1) ICBMs - world peace - end of large global conflicts 2) satellites - world communication and information - internet 3) early manned spaceflight - world view - environmental movement Right now we are developing ever more sophisticated satellite systems. We went from point to point satellite communication to systems that broadcast from a single point to many recievers (XM, Sirius, etc.) and eventually will have systems that will carry out multipoint communications - (satellite telephone, satellite broadband) Development of large space launchers like the old Nova rocket plans, but at low cost in reusable form, could make solar power satellites a reality. Future developments include the use of nuclear pulse propulsion systems to deflect asteroids from collision with Earth, and the use of the same technology to move rich asteroids into Earth orbit. Once there, these asteroids can be used as feedstockfor orbiting industries, manned by remotely controlled robots directed from workers anywhere on Earth, with products made in space and delivered to any point on Earth in minutes. Nulcear Pulse spacecraft will launch large factory systems into orbit and very large power systems into orbit as well as carry out construction of cities throughout the solar system - cities supported by the same system of space production developed for Earth's population. Very low cost rockets, made of propulsive skins and powered by space borne laser systems, will put a flying machine in every garage capable of suborbital travel to any point on Earth in a matter of minutes. Extension of this technology will permit easy attainment of orbit. Space factories over time will grow to build large pressure vessels at low cost and these will be used as farms to grow food and fiber for humanity. These vessels will also be adapted to space homes. With the low cost availability of luxurious space homes with areas approaching that of a small county, people will flock to space developments while continuing to work the factories remotely, but from space. The production of very large solar pumped laser arrays from solar laser cells orbiting inside the orbit of Mercury, will allow the capture of vast quantities of solar energy at extraordinarily low cost. This beamed energy will power industry throughout the solar system, and give wing to the space homes orbiting Earth. This will permit laser propelled homes to fly throughout the solar system with ease. Penultimately, these payloads will use vast solar pumped laser energy to power laser light sails on interstellar journeys. Laser arrays around other stars will power space homes and factories there as well. Ultimately, once human settlements have spread to the nearby stars, laser light sail spacecraft will be operated together from different star systems to create a high energy high mass collider of monumental proportions. Iron 56 shaped into appropriate forms will be collided at greater than 1/3 light speed at a predetermined point and time. The colliding masses will compress to create ultra dense materials. These engineered black holes will be made in collections and be caused to interact. These interactions will be studied. Ultimately, there will be a new sort of engineering possible. The engineering of black hole dusts. These dusts will be charged and discharged and interact gravitically and magneticaly and electrically - and a new sort of device will be possible. One that can distort and affect time and space directly. With this technology is may be possible to tap zero point energy, to build time violating regions, and perhaps make copies of devices created from zero point energy directly. If the last becomes possible, these devices could become quite common. Otherwise, they'd be quite rare. The difference this last bit of knowledge would make, if it exists, would be like the difference between finding and tending fires and being able to start a fire yourself. With the ability to affect space and time directly it may be possible that superluminal travel and time travel is possible. In that case humanity would be able to fill all of space and time - and all parallel spaces and times - if the many worlds interpretation of quantum theory are correct. If such is possible that may explain where everyone is - answering Enrico Fermi's paradox. Rising living standards mean lower birth rates, and space technology means larger range - together this means lower density of human numbers. |

"H2-PV NOW" :

If anything they are money sponges sucking dry the funding sources and a distraction from what will work. Here you fell into your own trap. By *you* adding the requirement that orbital craft must be SSTO *you* made the jump from sub-orbital to orbital design into a tough job. But infact a number of the sub-orbital designs are single stage as they are planned and adding a booster (second stage) will the next logical step to making these designs into orbital craft. Other suborbital designs are already planning to be using two stages and may just require a bigger booster to reach orbit. Yes, I know about the major problems for return. But what I am doing is showing that you had set up your own strawman agruement when you try to slip in the requirement that the craft be SSTO. CATS does not need SSTO, it needs frequent flights.

It is not appropriate to even call it "commercial passenger space industry". Of course it is. It's an industry that takes passengers into space, for pay. Especially as most of the protagonists want to develop the model further. It is doubtful that sub-orbital jaunts will become more orbital-like and less amusment-park ride-like. Actually, it's doubtful that they will not. Just about the first commercial use for aeroplanes was for passenger joyrides. SSTO requires a rethinking that is more fundamental than any of the plans posted in public to date. And people who think that SSTO is necessary for low-cost reliable launch need to do some rethinking themselves. People do get fixated about this for some reason. Space travel is very new, and the eventual configuration eventual lower cost access to orbit is difficult to predict. The SSTO model certainly seems to require some significant technological advances in materials science at the very least before it becomes viable. |
