There would be one nagging concern: the new KT-series rocket China is developing will be the world's most powerful rocket... That would be CZ-5xx, not KT. KT-1 is quite interesting in itself, but it is a Start-class vehicle, perhaps somewhat upgradable by adding strap-ons and things. http://www.astronautix.com/lvfam/lonmarch.htm |

news:sci.space.policy, Pat Flannery posted at Thu, 30 Oct 2003 04:09:19 :- The thing that's missing from all this is a rational reason to return to the Moon- it's lifeless, and we already know a fair amount about its geology; we can't afford a permanent manned lunar base because of the supply problem that such an endeavor would pose, and spending billions of dollars to get some more rocks is a vast waste of money. At least with Mars, we would get an inherently more interesting place to visit. The USA, using 1960's technology, needed under 7.5 years to go from Glenn-in-Mercury to Moon-Landing, with a delay of ?? caused by Apollo I. It is plausibly said that, without the sort of crash programme that was politically possible in those days, the USA could not possibly do it again, starting from now, in much less time. The Chinese have launched a 3-man vehicle, albeit containing only one man; its capabilities must be at least those of Gemini, first launched three years after Glenn. There must be a possibility of their reaching the Moon in this decade or soon after. Forty-Three may have in mind, therefore, that in order to be sure of not being beaten by the Chinese for the next Moon trip, it may well be necessary for the USA to start during Forty-Three Part I or II; and being beaten would be deeply embarrassing, and not something that he would wish to be seen as being responsible for. After all, he may be hoping that Forty-Four is in office 2009-2017, and is also Son of Forty-One. And he will be aware that, starting now, the PowerPoint engineering necessary before 2 Tue Nov '04 will be relatively cheap, easy, and safe; and a real effort before Nov '08 will only be needed if the Chinese are making progress enough to concern the average voter. Or, of course, there could be a more subtle plot behind it, intended to embarrass a Forty-Four who happens to be Mrs. Forty-Two. -- © John Stockton, Surrey, UK.

news:sci.space.policy, Dick Morris m posted at Thu, 30 Oct 2003 17:00:09 :- We certainly can't afford to build a lunar base with expendable HLLV's, You cannot maintain and build a Lunar Base without maintaining a "fleet" of suitable LVs; and since you cannot build indestructible LVs, you therefore can only do it if maintaining an LV construction capability. Such a capability can only be maintained if it is used. Therefore, the LVs *must* be expendable; and expended. That does not, however, mean that they must be single-shot. The vehicles, as far as practical, should be designed for a half-integer number of round trips; in other words, at end of full flight-worthiness, they should become Lunar resources rather than Earth junk. And a re-usable booster, when because of age no longer man-rated, can still be used as a launcher for inexpensive material. A quick test shows that a tonne of material which would currently (AIUI) be most welcome (suitably packaged) on ISS at present can be obtained merely by turning a kitchen tap on for an hour or so; and there must be much other material whose value in orbit is almost entirely the cost of putting it there, but which can be inadvertently launched into the Atlantic without much recrimination. -- © John Stockton, Surrey, UK.

First, Bush the Younger is not his dad. Second, the liberal Democrats don't run Congress. Third, Sean O'Keefe runs NASA, not Dick Truly. Also the plan is not a five hundred billion dollar monstersity, but contemplates a 7-10% annual increase in NASA's budget, which is doable. How can you know that? We haven't even seen a plan. If it costs them thirteen billion to develop an "orbital space plane" I can't wait to see the price tag for a lunar mission.

It could be there of course, but it's far from a sure thing. Ice is uncertain, but hydrogen is not -- the neutron spectra are pretty clear that there's plenty of slightly-buried hydrogen there.

A Proton/Ariane5/etc... size launcher can soft land around 6,000kg of cargo on the surface at a reasonable cost for supply purposes. Six tons? Could you document that and/or provide numbers?
