Back to the moon? When?
"Sylvia Else" wrote in message u... They're not quite as willing to risk killing people this time. Also, they're still trying to think of a convincing reason for actually going. B.S. The money simply isn't there to go as fast as we did during Apollo. NASA had essentially a blank checkbook for Apollo/Saturn development funding. They don't have that today.

"D. Orbitt" wrote in message ups.com... Also, you have to remember that much of the blueprints, all the tooling, the assembly lines, and almost all of the people that designed and built the 60's Apollo hardware, and all their skills, are long gone or retired and advanced in age. The blueprints aren't gone. That's an urban ledgend. Jeff -- "When transportation is cheap, frequent, reliable, and flexible, everything else becomes easier." - Jon Goff |

Back to the moon? When?
"John Schilling" wrote in message ... Mostly fear of failure. The surest way to never fail, is to never try, and while I expect NASA will eventually get around to trying to put a few more men on the Moon, they are going to delay as long as possible before starting each new step. B.S. It's lack of funding. NASA's peak funding was during Apollo/Saturn development. That level of funding has *never* returned and it *won't* return. The nation has different priorities today than it had when it was using NASA to show the world that the US was superior to the Soviet Union. No bucks, no Buck Rogers.

Even if you know it has been done before, that's not equal to being able to make it happen again quickly or easily, if you've lost the capacity to make those things exactly the same way. You have to reinvent a lot of the processes, find modern materials to replace stuff that's no longer available, or stuff that was not as safe (leather gaskets, anyone?) as modern replacements. You have to lay down a whole lot of infrastructure and start a flow of precursor materials, structures, and assemblies, a pipeline of materiel, and train up a whole new highly specialized workforce with skillsets that have been largely forgotten or have changed radically over time. It certainly is true that it isn't possible to start putting together F-1 engines at Canoga Falls next week. If, though, the desire were present to send astronauts back to the Moon to perform Apollo-like missions again as quickly as possible, rockets are still being built, and the Space Shuttle Main Engine could be pressed into service. The Shuttle, though, achieves thrust comparable to a Saturn V through the use of solid rocket boosters. So a new class of heavy-lift boosters will have to be designed almost from scratch, and it took time originally to proceed from the Gemini program's Titan to the Saturn. After all, rockets and missiles are still being built. Building something like the Lunar Module could be done without the need for special knowledge lost in the 1960s. So, while you have noted an important reason why it's taking longer than one naively might expect - since we already did it "from scratch" in nine years, we should be able to do it now in five. (And, after all, Titan rockets, like those used in Gemini, are still being made.) But a lot of things are not available off-the-shelf. Other posters have noted that the program is being done on a limited budget while NASA is busy with other activities. I suspect that is a larger part of the problem than the obstacle of having to repeat some work that was allowed to go to waste. But another part of it is that there is a desire to do it "right" this time. What was "wrong" with Apollo was simply its hasty discontinuance, and the failure to follow it up. These things weren't inherent flaws in Apollo itself, but in a way they can be seen as arguments against simply doing more of exactly what Apollo did, and then stopping again. What was "wrong" with it was its being a hang the expense crash program aimed at achieving prestige and not capability. The Air Force had a good solid research program going that ended up getting killed because of Apollo. If the Air Force had continued what they were doing at Edwards we'd likely have real capability by now. So the plan is this time to send larger Moon missions, as part of an effort to build a permanent base on the Moon. And to use the same hardware to send men to Mars. But since even the first step is being taken on a 20-year schedule, the chance of it being cancelled before anything happens... makes it hard to take it seriously. The fact that G. W. Bush's popularity is sagging has an effect on those odds. So the goal is to take at least a small step beyond Apollo - sending more people to the Moon, and for a longer mission. And to do it as a side pastime instead of a crash project. The wonder isn't that it's taking so long; the wonder will be if it ever happens. No point to it if the effort is not sustainable and at current launch costs it's not. -- -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

"Erich Kohl" wrote: First and foremost, let me just say that I do believe that the United States was actually on the moon. Kind of a silly thing to say. Of course we were, six times. However, I am in a debate with someone who wants to know why it's taking us (or anyone else for that matter) so long to go back there. After all, if it was done once before with 1960's technology and know-how, what's causing the delay in the expedition this time? Money. The Apollo program was an enormous expense, cancelled by the Nixon administration for exactly that reason, and it's never been politically viable to spend that much again (and still isn't now, which is why it's taking 20 years to do what was done in less than 10 back then). My theory is that it must have something to do with politics and budget, combined with the fact that it might not be as high of a priority as it once was when the U.S. was in an overt space race with the Soviet Union.

I have some news for you Google is in fact developing software which will help to classify pictures. As I said on the Moon this is largely academic. You can communicate a decision in 3 secs. On my recent hol;iday in Syria I saw cliffs from the coach. To a geologist these mean one thing water in the past. In fact the name of your most recent mess comes from such a cliff "Al Iraq". If I were to put "Al Iraq" into a search (we assume it understands Arabic) it would find all the places were there had been water (or methane in the case of Titan) at some time in the past. This is now under developmrent. As I said for most purposes this is academic although interesting. Transmitting the picture and having a decent attenna is a much more cost effective solution. However the question of how we test a hypothesis is interesting. Can we, for example, run a series of simulations and come up with a hypothesis that would explain the shape of rocks? Well in a sense we have. Start off with a black hole and some gas and hey presto we get a galaxy. We have indeed tested our hypothesis. BTW - The only geologist ever to fly on an Apollo mission was Harrison Schmidt. Geologists were at mission control, as they would be for a robot. : :Lunokhod was ven cruder.

Bandwidth, power, time delays, etc. People are still orders of magnitude better. But 3 secs is not long for a decision. Bandwidth (from the Moon) is easily HDTV. From Mars you have a delay. still a geological assessment is possible in a timely way. Anyway are you seriously twelling me that the best geologists would be on Mars. Ian, I really wish you'd learn something about what is actually possible given the current state of the art. It would keep you from posting oh so many silly things. You say a lot of silly things too. While we are on the subject of cliffs can anyone explain to me why Americans are capable of winning Nobel Prizes yet are such gits when it comes to managing their affairs. How can America time after time get itself involved in the messes it does? Yet win Nobel Prizes? -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson Yes there is nothing beyond 3KPa according to Bush.

Parker made the phosphor on my monitor glow in such a way as to indicate that: You say a lot of silly things too. While we are on the subject of cliffs can anyone explain to me why Americans are capable of winning Nobel Prizes yet are such gits when it comes to managing their affairs. Yes, Ian. We'll explain that to you right after you explain to us why you continue to bugger little boys. |
