NASA's New Mission to the Moon
mattnyc99 writes "Popular Mechanics has a new, in-depth preview of NASA's Orion spacecraft, tracking the complex challenges facing the engineers of the CEV (which NASA chief Michael Griffin called 'Apollo on steroids') as America shifts its focus away from the Space Shuttle and back toward returning to the moon by 2020. After yesterday's long op-ed in the New York Times concerning NASA's about-face, Popular Mechanic's interview with Buzz Aldrin and podcast with Transterrestrial.com's Rand Simberg raise perhaps the most pressing questions here: Is it worth going back to the lunar surface? And will we actually stay there?"
Will we go back to stay? not if it's for science only, IMHO it will take private companies to make space travel, including exploting the moon for it's resources, to make this 'permanent'. NASA has no where in it's mandate to do anything except research.
What for? Surely this is just another presidential exercise in sticking it to the Commies?
True, but there are other benefits. Learning how to colonize space would be a biggie in my book. Besides, if we can't go to the moon, we don't stand a chance at going to Mars, Europa, Titan, or possibly beyond our solar system. The moon is the first step.
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.
As the folks at Goddard expained it during the Moon Math student competition, "When you go camping, isn't it a good idea to try setting up the campsite in your backyard first, 600 inches away, so you can try out everything, or run back in the house if you forgot your flashlight, make sure you remember to bring everything, and *THEN* go camping for real to somewhere 600 miles away?"
That's a largely non-obvious reason for using the same basic vehicle for both mission sets.
"Win treats sysadmins better than users. Mac treats users better than sysadmins. Linux treats everyone like sysadmins."
Funny how after 30 years of listening to people say "when will we go back and who will that be?" now people are saying "Is it worth going back to the lunar surface?" How did this reversal of thinking happen?
We have a lot more information than the last 3 moon attempts. Time was the only answer you could know about right and wrong was what you could think of on your own based on what you saw in the sky and how much spare cash you had.
Now the answers for everything are downloadable. You don't need to come up with your own answers because the internet has the answers for you. The change in where our information comes from has changed our opinions.
...though, methinks that this whole "return to the moon" wouldn't even have been brought up had the Chinese not boasted about what they hope to accomplish.
It is by my will alone my thoughts acquire motion; it is by the juice of the coffee bean that the thoughts acquire speed
Would it be worthwhile to launch space missions from a lunar base? It would seem to me that because of the lower gravity you would need less power to reach escape velocity - or am I incorrect in this? That could be one potential bonus of going back to the moon.
so give it to people who are willing to work for it rather than some crappy rat hole like welfare. I'd much rather support engineers than drug addicts. With the best answer to me being "Don't fucking take my money in the first place!!!"
Paying taxes to buy civilization is like paying a hooker to buy love.
building a colony at a Lagrangian point makes a lot more sense than going to the moon especially as a way station to Mars http://en.wikipedia.org/wiki/Lagrangian_point
The moon is the first step.
Why? Colonizing the moon is a drastically different undertaking from colonizing Mars. The moon is essentially a vacuum. It's cold. It has no useful resources to speak of (and no, He3 won't be useful any time soon). 1/6th Earth's gravity. And it's fairly close.
Meanwhile, Mars has water. And abundance of minerals. A thin atmosphere containing useful gases. A surface temperature that actually breaks the freezing point occasionally. Double the gravity of the moon. And it's so far away that getting there has proved to be a surprisingly difficult undertaking.
Honestly, the idea that colonization of the Moon will tell use anything useful about colonizing Mars is, frankly, silly. The methods that would be used for the two projects are *completely* different. Meanwhile, we can't even build a self-contained biosphere on *Earth*! Maybe we should try tackling that drastically simpler task before we start planning Moon bases.
In that case, I hope the Chinese boast more often about big, hairy, audacious space goals.
Even under the most dire/optimistic scenarios a lunar facility isn't gonna be much of a viable 'lifeboat' for generations yet. Indeed if things go seriously awry it's probably the most untenable place to be for any calamity except a fast-acting/highly-virulent/fatal terrestrial biohazard, and then you'd likely just get to live somewhat longer and die a premature death of a different cause. After a terrestrial catastrophe a lunar facility likely won't contribute much to future generations but an interesting monument. Rather a planet of 6 billion with a huge biosphere has so much more in the way of odd nooks & corners for refugees & resources.
Except a lunar facility is going to be markedly different then anything space-based. Significant gravity, a surface, 2 week bright/dark cycles, huge dust & debris issues; except for lack of atmosphere they're almost entirely different problem sets. A space station is certainly the better R&D environment for spacefaring development. As to Martian R&D Earth as good, and substantially cheaper/more-amenable venue then the moon offers.
Except that asteroids are probably a far better materials supply source and can be got roboticly, with their materials easier separated, refined, and then sent on to Earth in space then from the moon. Furthermore while He3 is promising we've yet to achieve fusion that could take advantage of it and those power sats would probably do as good a job with less complexity then a lunar-fueled terrestrial fusion system anyhow.
Except any manned base is going to be fouling up the local environment and require far more support then just installing spares & alternatives for everything. Again, the moon is good, space is likely better.
Because the moon is the only possible frontier? Not our oceans, deserts, mountain ranges, arctic & antarctic regions? Not more abstract frontiers like science, technology, sociology, psychology, diplomacy, etc.?
I'm honestly not trying to be contrarian but your reasons strike me more as rationalizations. Nearly all could be done better/cheaper using unmanned systems or directly in space. I'd hate to see a lunar base become another dead end like our hopelesly compromised space station, doing expensive science of minimal import or quality.
I don't read ACs: If a post isn't worth so much as a nom de plume to its author then I wont bother either.
The idea of landing a man on the moon was initial conceived in 1960. Kennedy made his famous speech in 1961. By 1969, NASA had launched and recovered Apollo 11.
Flash forward to 2007. Presumably, we know how to get to the moon, since we've done it before. Computing and aerospace technology have both advanced considerably in the intervening 46 years. But now, instead of getting there in less than 10 years, they want to take 13?
Something is seriously wrong with this situation.
God invented whiskey so the Irish would not rule the world.
Yes, yes, and yes. The problems you mention have no chance of destroying all life in the universe (to our knowledge). Keeping all life on one planet does have that chance.
Life itself is more important that starving orphans. There, I said it.

Well, let's see. 1/6th gravity might be nice for some things. It does equate to 1/6th the difficulty in managing heavy objects. Vacuum is, amazingly enough, common for many likely working environments in space. We need practice; better to do it around a developed moonbase with medical facilities, manufacturing and so on than around some asteroid that has a lot of something we want, plus vacuum. It's not necessarily "cold", by the way, it is in vacuum, which is something else entirely. There is plenty of energy falling on its surface from which heat can be gathered. And power. In any case, it isn't like you're going to lie on the surface naked. Another thing is it is closer than anything else, and once we have a base there, going other places is a lot less costly -- launching from a 1/6th gravity well is much less costly than launching from a 1G gravity well. Not just into space in general, but to Mars, to Earth orbit, moon orbit, everywhere. There have been many suggestions about how to mine the moon's resources and get worthwhile products from them. Once there and we get a little practice, I have little doubt there would be more of the same. If materials can be obtained to build spacecraft, for instance, then we're WAY better off with a moonbase. It's a great place for telescopes, too. And RF research. And vacations (I'd love to have a 1/6th G environment to practice martial arts in, or to have sex in, or even to just turn backflips in.) As for creating a self-contained biosphere, you know what they say about necessity being the mother of invention.
I've fallen off your lawn, and I can't get up.
I don't know where you got your information, but the moon has - at some point in it's orbit - the same relative velocity as the earth with regard to mars. This is unavoidable, as the moon orbits the earth, if you'll recall. Launching at the appropriate time will ensure no loss with regard to the moon's orbit. However, with 1/6th the gravity well, the same amount of energy will result in a higher velocity, or less energy the same, with regard to a trip to mars from there as compared to the earth. It's just math. And of course, there is no air resistance, no weather, and little air traffic to contend with.
How about not making the terrifically dim assumption that we can only do one of those at a time? Do you fall over when you chew gum? Sheesh.

Okay, perhaps I'm missing something, but in order to launch from the Moon to Mars, you need to get fuel to the Moon first. You can't make fuel on the Moon, after all. There's nothing to make it from. So you have to lift it out of Earth's gravity well. So, let's say you do that. So you burn a bunch of fuel to get a bunch more fuel out of Earth's gravity well and deposit it on the moon. Then, you launch from the Moon, burning yet more fuel to climb out of the Moon's gravity well, and a bunch more to make the shot to Mars.
So, tell me... where is the savings, here?
I'd mod you up, but I can't, so instead I'll just argue the opposite.
Let's assume that all the money in the OECD spent by space agencies gets pumped into working on the aid shortfall, assuming the 0.7% GDP goal is the proper goal. That's about a $24 billion drop in a $50 billion bucket. The rest could be made up by a goodly chunk of Microsoft profit money, leaving them $10 billion. However, this is only assuming that the 0.7% is the only goal. There's also the problems of health care (that leftover $10 billion could give the 45 million uninsured Americans about $218 per year). Afterwards comes education, housing, and the impoverished in the OECD that would be overlooked by our 0.7%.
So the $24 billion would be a step in the right direction, but you forget what we buy with that money: a look over the next hill. The Chinese explored for a bit, arriving as far afield as East Africa and beginning colonies around their area of the world. They nearly dominated the East. After 30 years of this, they turned inwards and burned their fleets trying to achieved Confucian inner perfection. That insular behavior undid the progess achieved under their age of exploration. The Chinese never achieved the perfection they sought. In contrast, Europe achieved the wealth and power it sought, whether for good or ill, and now it and its transplant nations (the rest of the OECD) are the most prosperous in the world.
The $24 billion we spend wouldn't eliminate poverty if spent on poverty, but it may if it's spent on reaching upward and outward.
What's this? Another weblog? On transit?
Sextant? For the same reason I would want to take one with me on a sailing trip to Hawaii. Yes I have a GPS and a backup GPS on my boat. I also know some one who had two GPS units fail while en route across the Pacific. Had to fall back on dead reconing (using the knot log, clock and compass)
If the on-board computer smokes you would need the sextent to measure your orientation.
Most of Africa would kill to get what the poor in the US have.
The only people starving in the US are nuts (anorexics, bulimics, crazy street people that won't take help).
We spend millions per year on free health care for fat 'poor' people. There are no fat poor people (truly poor).

You are, of course, correct in that little distance is gained if the moon was to be used as a waystation to Mars. I had read the gp to mean that the moon is closer environmentally to Mars. It is a better place to R&D the technologies we would want to take with us to Mars. Whatever habitat module, vehicle, and local resource extraction NASA comes up with for Mars, should be tested on the moon first.
