I hate to rain on anyone's parade, but does anyone actually
believe this is going to happen? Given several states, and without going into any of these in detail--the state of the economy, the state of world affairs, the state of the deficit, the state of science in the present day, the multinational character of today's world economy, the direction that the American public's interest and imagination has taken since the '60s--does anyone actually think that we're going to actually see a moon base happening in the near future? I mean, sure, it *could* happen, anything's possible, but it's gonna take more than a glib election-year statement from the President to convince me that the show's on. The very first thing that is lacking in this situation, for this to occur, is idealism. Americans' hearts and minds, speaking in broad generalities, are not into this as they might have been back in the '60s. The second thing that is lacking is--a reason. Back in the '60s, as we all know, it was reason enough that the Soviets might take command of space away from the U.S. But today the reason to spend all this money is . . . ? There is nothing so critical, so pressing, that the money won't be siphoned to other more pressing concerns first. Even if there is a good, honest start to the project, it's so costly that over the time it takes to develop it, the money will be whittled away slowly, like Congress did to the space station. The once lofty goals will be constricted further and further as money is sucked here, there, and everywhere. Private enterprise might have a chance--profit is a strong incentive. But I don't see any private concern willing to invest all that money without government assistance of some sort, so we're back to square one. I mean, we couldn't even really get a working space station in orbit, at least not in the long-term sustaining way we originally envisioned it, and we're talking about a moon station? I don't think so. Time will tell, and I will be happy to be proved wrong, but--get real. |

Thanks. IIRC years ago NASA gave daddy Bush a half trillion dollar price tag for going to Mars. And 500 billion is what the hair spray heads on my TV news were saying. Am I correct in believing the Mars Reference Mission will be much cheaper? (I couldn't find any cost guestimates during my quick perusal of the URL) I've seen estimates from $30B to $50B. Certainly more than a 5% increase in NASAs current budget per year. Zubrin cites a NASA estimate of around $30Bn, as I recall; he cites his estimate of $20Bn for Mars Direct, and then claims if done privately it'd cost $10Bn. g Looking at the MRM - I've been trying to find a copy for a while, but the links I had were broked - it *is* more complex than Zubrin's plan, which in part would account for the additional cost - rather than develop an HLV, a hab, and an ERV, you need to develop an HLV, hab, ERV, MAV, and surface lab. Admittedly, the last is essentially a specialised refit of the hab, but still; it also calls for half as many launches again as a Mars Direct baseline. It does refer to a total cost, but doesn't give it; there is, however, an estimated cost breakdown, not covering unmnanned precursors or operations costs. "The Mars Study Team recognizes that, even with the significant reduction in the program cost achieved by this Team, the Reference Mission is probably still too expensive in today's fiscal environment. More work to further reduce these costs is needed." [Their subsequent recommendation is delightful - "Seek alternative solutions or effective approaches to cost reduction in each of the areas cited above. The efforts may require revolutionary changes throughout NASA, the aerospace industry, the United States, and the world."] The HLV seems to account for a quarter of the total cost - is $8-10Bn enough to develop something with about 200t throw-weight? -- -Andrew Gray |

![]() I say get a permanent industrial presence started on the moon and let corporations take over space exploration from there. You do realize how many decades this will be before it's true? And how much mass needs to be launched to the Moon before this becomes a reality? In the meantime if you can afford to launch that much mass to the Moon in a cheap enough fashion to be affordable, your cost to launch space probes becomes low enough as to not make it any more practical to launch than from Earth. OK, let's see if I can clarify this further. **** the probes. No more hard science at the expense of the American taxpayer. Yeah, the slide rule-and-pocket-protector set might get off on what happens to flat worms in 0 Gee, but we don't care. The point of space travel, in the end, is to enrich the lives of all humanity, not just the scientists working on the various projects. This is something that NASA has forgotten and of they don't figure it out soon, there might not be a NASA for much longer. So, in order to make space profitable, there needs to be industry there. There needs to be some sort of commercial interest in space aside from near earth satelites. The moon is a good start. Belt mining would be a better secondary goal. The point is that once you get the commercial ball rolling in the direction of space, science can hitch a ride on its coattails, not the other way around. Doc -- "I'm at peace with my lust.

NASA's $400G (not $500G) estimate for SEI was an "everything including the kitchen sink" project that included new Saturn V-class boosters, Shuttle II, an additional Space Station for orbital assembly, lunar exploration and bases, and a full base on Mars, not just exploration missions. Truly basically went to Capitol Hill and asked that everything on NASA's wish list since 1972 be funded. Predictably, he didn't get far on Capitol Hill, and Truly shortly thereafter was gone from NASA. Am I correct in believing the Mars Reference Mission will be much cheaper? (I couldn't find any cost guestimates during my quick perusal of the URL) Yes, much cheaper. While still expensive, the MRM has its feet grounded in reality somewhat better than SEI did. Brian |

Not what I would call "never." So, let me see if I get this straight. This means launching the stuff required to build them to the Moon, assembling/building them there and then launching them? Nope, you don't have it quite straight yet. It means launching the expensive, complex parts -- like the circuitry -- to the Moon, but the most massive parts (especially the fuel, and probably also the frame) would be lunar materials. In addition to being cheaper (once this lunar infrastructure is in place), you also have the benefit of a much gentler launch for your delicate instruments, as well as a more flexible development environment (i.e. you can build and store the thing in vacuum until launch, if necessary to avoid oxidizing any components). ,------------------------------------------------------------------. | Joseph J.

The plan is valid, you just need to change the starting date. Maybe 2017 instead of 2007. Brian The point to a reference mission is to continually update the projected project plan for the current status and capability. The date is *valid* with the caveat that it isn't carved in stone. It is simply a fairly realistic project plan in terms of delivery and cost. The Mars Reference plan was adjusted radically in the mid-1990's when in situ went into vogue. The problem with references missions is that you really need to stay on top of the plan and keep updating it. The thing that caught my eye is that it is fairly trivial to find a Mars Reference Mission on a NASA website. A google search for a Lunar Reference Mission gives the usual sort of mix of private groups and universities. It is also even possible to trace the monthly addendums to the Mars reference mission that occurred over much of it's life. How current is the Lunar Reference Mission? Is there even a Lunar Reference Mission on file? I know that there are hundreds, if not thousands, of individual papers about lunar development. But, there does not be the same sort of cohesive pattern that has emerged for Mars. |
