OTOH, the cost of these missions is likely to be such that there isn't any other way to do it, unless the U.S. wants to spend 5% of GDP on space exploration. Agreed. But the scientific community needs to get a bit of perspective. If we develop space, and get a decent amount of infrastructure and long-term living-and-working population in orbit and on the Moon and a more varied (and cheaper) selection of launchers, then those missions which are hideously expensive now will be considerable less expensive. It makes sense to focus on getting a significant offworld presence first, and *then* do those offworld pure-research experiments that give insights into cosmology and whatnot. ,------------------------------------------------------------------. | Joseph J.

For that kind of money NASA will very hard pressed to get anyone on the moon alive and back let alone Mars. So yes, I believe very few new missions will be funded, if at all. Ignoring Mars (which clearly was not a priority in the rumored announcement -- and quite rightly so), there is no reason a vibrant lunar base couldn't be maintained for that amount. Of course, whether it could be done for that amount *by NASA* is another question. I do have a deep concern that these ambitious new goals might be approached with NASA's business-as-usual methods, in which case, they will almost certainly fail (or be long, drawn-out, partial successes, like ISS). But OTOH NASA needs to take a convervative stand on accomplishing these feats. That means it shouldn't try to invent wholly new technologies, but merely adapting existing technology to fit the need. I would argue it shouldn't do either one. Instead, it should act as a customer, offering to pay $X for the safe delivery and return of three crew members to a certain point on the Moon, $Y for a subsequent mission of the same requirements (where Y X), etc. Let the companies trying for these prizes decide whether it's better to invent new technology, or use something off the shelf. ,------------------------------------------------------------------. | Joseph J.

The orbital flights would conduct photo reconnaissance of the Martian surface before sending landing craft, What exactly would be the point of this? Anyone? I found this a little odd also. If you want long duration experience, do you really have to go to Mars orbit to get it? There's no substitute for propulsion and power systems being tested in their target environment. |

"John Cody" writes: I'm not wholly against the idea of a crewed Mars orbital mission (particularly if it includes flybys/landings on Phobos and/or Deimos as a bonus). It was the mention of 'photo reconnaissance of the Martian surface' as the primary aim (as opposed to Phobos science or the real-time teleoperation of Martian robots) that confused me. Is there *really* anything useful we could learn about Mars that could be obtained by the early 21st century equivalent of an astronaut pointing a Hasselblad at one of the LM windows? When you're flying back anyway you can avoid sending all data back via the DSN bottleneck (and just take along a rack of harddisks). If you look at the earth surface mapping missions (using STS) you will easily see that the sheer amount of data gathered with some instruments are a real showstopper otherwise. That does not require a crew. |

(although this would not prevent the lander from relying on Mars-manufactured fuel). The journey to the Moon's surface is totally pointless in my opinion. The ISS is a far better platform to test a year long mission, hardware performance, reliability and servicability in space. Where else would you perform long term experience exercises in a low gravity, low pressure environment? |

Good to see the full text of the story; all the news outlets have edited out
vital bits, like when Shuttle would be shut down. After completing Station construction was my guess, but it's good to see it confirmed. Good work on getting this story out, Keith and Frank! Some implications I see... First, the current NASA manned space organizations are seriously and fundamentally broken, see the CAIB Report for details. Any major new initiative that depends on them absent radical reform is going to end up like Shuttle and Station - years late, billions over budget, and producing systems so complex and fragile as to be at best of marginal actual utility in the field. The current NASA was built on the hasty ad-hoc Apollo structures that should have been discarded with the end of that project. Instead, for over thirty years they've been set into ever-accumulating bureaucratic concrete. The result may well be unreformable for all practical purposes - certainly the backsliding after Challenger, the prolonged mess of Station, the loss of Columbia, and the current organizational attempts to pay only lip-service to the CAIB reforms don't bode well. My take is, reforming the main current NASA manned space organizations, JSC, KSC, and MSFC, would be like trying to shovel out the Augean stables with a teaspoon. The only NASA option with a reasonable chance of success is to start new organizations elsewhere and slap the NASA logo on their buildings, while winding down and pensioning off the existing NASA manned space bureaucracies. I see two key litmus tests for whether this new Return To The Moon Then On Outward policy has a chance of succeeding, one near-term and one a bit farther off. First, where will the new CEV, Crewed Exploration Vehicle program be run from? I understand that JSC, KSC, and MSFC each already have their own OSP program offices. These need to be radically trimmed if not shut down entirely, and CEV run out of a fresh-start new place. Second, what will happen to the current massive Shuttle operations bureaucracies after Station is assembled and Shuttle shut down? These need to be wound down and pensioned off, with a new outfit set up to run the return to the Moon missions. If CEV is handed to the existing organizations that have screwed up Shuttle, NASP, X-33, and SLI over the years and are currently working on OSP in what is at best a very nervous-making absence of external scrutiny, it's a very bad sign. If Return To The Moon is handed to the lineal unreformed descendants of the Shuttle operations organizations that brought us Challenger, Columbia, and a half-dozen missions a year at a half-billion a mission, forget ever seeing a practical permanent return. All the preceding my humble but moderately informed opinions... Henry Vanderbilt |

What if this means "No more galileos, cassinis and space telescopes UNTIL" those can be launched from lunar surface ? But this is essentialy the same as never, as things stand or are even projected. You must have a very limited definition of "never". We could be launching craft from the lunar surface in 20 years easily. If in a hurry, then 10-15 years. Not what I would call "never." It means long delay or even cancelation of real science projects over a bunch of unneeded footprints. No, it means delay or cancellation of science projects in favor of real development of space. And I say, great! The first thing the Bush administration has done (or at least, been rumored to be claiming to do) that I've agreed with. Frankly, I really don't care all that much how much dark matter and dark energy there are in the cosmos. But the fact that the total lunar population is zero, and I couldn't take a vacation there even if I were a billionaire -- these things I *do* care about. We need to get off this rock, and to provide abundant clean energy to the poor saps who are still here. Science projects isn't going to do either of those, but space development will. ,------------------------------------------------------------------. | Joseph J.
