And yet that doesn't seem to be progressing with great rapidity, either. Yes, because almost nobody has tried. The only great progress seen in that department so far was the introduction of Russian launchers. We'll see how SpaceX does. It seems that EVERY new launch system I can remember promised to reduce cost of getting a pound to LEO to the $100 range. Uh, no, practically none of the new launch systems which were actually *carried through to operational status* made any such promise. (The EELVs made far less ambitious promises of very modest cost reductions.) "You can't win if you don't play." is still at least an order of magnitude away, even using 'old' Russian technology which they are willing to 'under price in order to get hard currency... Whether Russian launchers are actually underpriced is not clear. They *are* inherently cheaper than Western designs, due to more automation on production lines and much less manpower-intensive operations, even if you disregard the small matter of lower wages. Current costs for most launchers apparently are in the $5,000-$10,000 per pound range. Russian launchers are already well below that range, possibly a long way below it if you have a sharp negotiator and are doing something unusual (that is, something where they can't be accused of undercutting Western competitors if they offer you a big price break). In fact, the actual cost of getting a pound to LEO doesn't seem to have moved even a single order of magnitude over the entire history of real space launchers... Hardly surprising, given how little real innovation there has been in launcher design, and how few truly new launch systems have been developed, for most of that history. The stunning cost reductions in electronics in the same period were not achieved by refining production methods for vacuum tubes. Nor did they come from pioneering initiatives by vacuum-tube manufacturers. :Indeed, you can make a half-plausible argument that this is already true: :that even at today's launch prices, it makes sense to accept mass growth :to save engineering man-years. But not much. When the vehicles still cost you hundreds of millions of dollars, it simply doesn't make much sense to put 'cheap' payloads on them. When the payloads cost billions or even tens of billions to develop, it can and does make sense to buy more hundred-million launches to reduce development costs (even disregarding the possibility of launch-cost reductions via bulk discounts). Except in a few vaguely-mature areas like comsats, the payloads cost *much* more than the launches now. ...However, we have to face the fact that the overwhelming majority of taxpayers simply don't care about space and consider it a waste of money. The overwhelming majority of taxpayers like space exploration (hint: ISS is not doing exploration) and think modest funding for it is a good idea. What they don't support is the sort of funding that would be needed to do manned exploration the JSC way. The logical conclusion from that is that we can't do it the JSC way, not that we can't do it at all. ![]() :notable: the single strongest predictor of success was private funding, :mostly because it meant unified, consistent leadership throughout.) But to attract a lot of private funding there needs to be some significant economic advantage over current providers. Very few of the arctic expeditions promised any sort of economic return at all. Private funding doesn't have to mean profit-making ventures (although it does help -- profitable projects can easily get up into the billions, while non-profit private funding tends to top out in the low hundreds of millions, last I heard). -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |

If memory serves, there are a number of features in Antarctica named for various expedition sponsors. (And I just noticed, looking at a map, that among the mountains there is the mysterious "Executive Committee Range". I kid you not.) Selling naming rights would be hampered somewhat by the fact that names on astronomical bodies are not generally recognized until/unless approved by the IAU. That adds an element of uncertainty to the process. -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |

I remember original Shuttle promises of prices in the range of $100/lb to orbit. Then they started compromising. Even without compromises it wouldn't have reached $100/lb, or anywhere close to that.

It's highly unlikely it would have come down much even with one of the original designs - which would have shared many of the same maintenance and operating costs, and would have been even more more expensive to research, develop, and build.

The required flight rate to 'earn back' the development cost would have been too obviously beyond what future congresses would have funded. And that's the key problem with both a notional alternative STS and the alt.space movement - future launch rates are speculative as hell. You need to fly a lot of payloads (regardless of whether your launcher is expendable or reuseable) before your investment is paid back. Then you need to *keep* flying payloads at a high rate in order to remain profitable. (Or 'profitable' in the case of a government system.) If you can't fly enough annually, you end up in a 'coffin corner' - stuck between the unpleasant choice between raising your rates or going out of business. (It's hard to cut expenses significantly unless you've been less than bright in how you organized your business, the least likely people to 'get smart' and fix the problems.) D. -- Touch-twice life.
