The Energia has been launched only twice, however, which is a quite low number to have confidenxe in it. It is clear that the Moon/Mars program is going to be international, with Russia playing a role. A space intiative by Dubya is *not* repeat *not* going to be an international effort. It would be unversally seen as US-prestige-project (at least outside the US), and noone who could add something substantially helpful is going to do so. Maybe some countries like Botswana might add their full space expertise... Assigning the heavy lifting job to the Russians would provide a major boost for their economy and national prestige (important not directly to the program but to Russia's position in the world w.r.t. the US), and give us the payload capability we need at almost certainly a lower cost than developing new hardware in the US. I can't prove that last, but it makes sense, looking at program costs and engineering salaries in the US versus those in Russia. We might save billions of dollars by reviving the Energia. Russia does not have the money to start a Energia production line, and it seems to be the consenus around here in ssp that the US are not going to spend taxpayer money abroad. And heavy-lift capacity has both a public-reltions angle (my launcher is bigger than yours) and a military one as well, so it seems unlikely that this part of the mission is going to be contracted outside the US. The Energia is modular and adaptable to both side-mounted and inline stack configurations, making it a very flexible launch system. Both Boeing and Lockheed have worked with Russian engineers and hardware to develop new profitable launch systems. So it is possible they would not oppose such an arrangement with respect to Energia and might even propose it as an option. So go ahead, what's wrong with this picture? (I know you started thinking up obvious counter-arguments at the first sentence.) Well, You concentrated a bit too much on technology and economy. Both do not seem to be relevant to those in Washington DC. Regards Robert Kitzmueller |

[deleted] A Saturn V-class launcher really may not be necessary. It may prove much more cost-effective to use heavy EELVs and on-orbit assembly, I don't know. A Shuttle-class 2-stage VTOL RLV can do the job, with the addition of an LEO refuelling capability. Just refuel the Orbiter stage in LEO and it can do the TMI/TLI burn.

As far as I know, the Energia launch pad and processing buildings still exist, as well as some mothballed Energia stack elements. (I have seen an estimate of $100M for refurbishing the Energia launch pad.) The documentation and tooling necessary to revive the program still exist, as they do not for the Saturn V. Many of the engineers who worked on the program must still be in business. I wonder who made that estimate. :-) In terms of the Saturn V, the documentation DOES exist. The tooling does not. However, much of it would be replaced anyway. I think the biggest problem would be finding a place to store/build the S-ICs. Of course if you shut down the Shuttle, then you have the VAB. And can just back modify LC-39. Everything old is new again. Of course, I'm not sure HL is the way to go. Especially with NASA wanting to do it. Patrick |

Robert Kitzm=FCller wrote in message ... True. I do see your point. It is worth noting two things, though--the launcher performed perfectly on the first launch, even though the payload did not, and also performed perfectly on the secon= d launch; and the Saturn V had only two launches behind it (IIRC) when it was used to send the Apollo 8 crew to the moon. =20 An Energia revival would of course include extensive testing. Well I agree to what You write above. I also think that Energia would be the best choice made on purely technical terms, even if not without issues.

I think both versions are incorrect. If you= are saying something else, please re-phrase. A bit of both, I think. Bush will invite other countries, but only on=20= his own terms, which might not look too pleasing to others. I rather suspect they are going to be either calculated to be not too inviting or unwittingly treading on the sensibilties of prospective partners. (With Bush, you can never be too sure...). And a lot of countries which did in the past collaborate with the US on spaceflight will not be too eager anyway, for a lot of different reasons. Lets look at the main contributors to ISS, who are/we=20 USA, Russia, Japan, Germany, France, Italy. So the US take the initiative. Who will follow? (Taking into account it is likely to hurt ISS: maybe no more shuttle flights to launche Kibo and Columbus, as well as solar cells=20= etc... maybe just reduced shuttle flight rate and cutting US build=20 modules if there are still any left to be cut - anyway the money has=20= to be taken from somewhere) Russia? Maybe, but they do not have that much money to spend by themself, at least not enough for reviving a production line of launchers bigger than anything needed on the commercial market. Germany and France? After being insulted repeatetly? When their ISS module is still on the ground, while the US and russia have all the modules they are willing to fund in orbit? Japan? Which also would suffer from any cut on ISS, and which has economic problems enough to bow out without offending anyone? Italy? Maybe, but I do not see them paying for Energia anyway. Their space budget (and GNP) is a lot less then that of others. Again: Those countries which would come into my mind collaborating with the US have a lot to lose if ISS suffers for it, which seems inevitable to me, and some may remember some insults, Bush related ones as well as space related ones (look at the stories of ISS and Spacelab for starters). The UPI story mentioned Ariane and Soyuz. I doubt Keith Cowing made that part up, and I doubt his sources said it just for fun. I have yet to see something firm on the whole issue... Russia does not have the money to start a Energia production line, a= nd it seems to be the consenus around here in ssp that the US are not going to spend taxpayer money abroad. =20 This consensus may only be apparent, or it may be real and incorrect.= The US spends billions of taxpayer dollars abroad every year--more so= last year than usual. Not on big ticket items with high visibility. I would be fine with a stictly US program, anyway, and I bet a majority of Americans would be fine with one too. But I think it's unlikely. We have a hard time holding a grudge. If You say so... And heavy-lift capacity has both a public-reltions angle (my launcher is bigger than yours) and a military one as well, so it seems unlikely that this part of the mission is going to be contracted outside the US. =20 If Congress is presented with alternate plans to a) buy Russian rockets and save billions, or b) use rockets built by American worker= s and pay accordingly, it will be interesting to watch how they vote. Districts with heavy aerospace presence will tend to vote differently= than those without. The issue would be muddled very soon, assuming anyone would present Plan A at all to the congress. Of course the Russians might present us with a breathtaking markup (a= s they have before) and I hope we would balk in that case. The russians are going to charge as much as they can, as proper capitalists should... Well, You concentrated a bit too much on technology and economy. =20 True; politics could make the whole thing academic anyway. Politics *is* going to make the whole thing academic anyway. A Saturn V-class launcher really may not be necessary. It may prove much more cost-effective to use heavy EELVs and on-orbit assembly, I don't know. So You say the discussion is moot anyway?

Assigning the heavy lifting job to the Russians would provide a major boost for their economy and national prestige Trouble is, if the American taxpayers are paying for the program, they will expect the jobs to stay at home. And since every penny spent on imports has to be earned by the sale of exports, and we can't (although I admit the U.S. has tried) force people to buy our products, the response to an increase in imports is to throw people out of work until they can't afford imported products, when tariffs are not permitted by treaties such as the WTO. If Russia could get rid of organized crime - instead, there are suspicions it has friends in high places in government - or at least reduce it to the dull roar it is in the U.S., one can't ask more of Russia than we do - making it stronger might be less of a dangerous thing.
