Fine, you pay for it.
EDIT: Sorry, realized a split-second after I posted this how rude that comment is. I don't mean anything toward you personally. I just think something as expensive as going to the moon should serve some greater purpose than "remember that we went there before." I think the huge budget cuts NASA has endured are criminally stupid and short-sighted, but what specifically do we gain by going back to the moon at this point?

In the short term, sure. After a frost in Florida, which caused the Challenger disaster, there should have been a more flexible launch window to recheck everything. But a 7 year goal to go from where we are to the moon, when in 1969 it took 8 years, should be relatively easy if we really are as advanced in that time as we let ourselves believe. It shouldn't even require much of an increase in NASA's budget.SlyReaper wrote:Putting inflexible deadlines on rocket launches has historically proven to be an absolutely disastrous idea.

That's another silly idea, since we still need to get all the materials for the rocket out of Earth's gravity well to begin with. We gain nothing by moving them to the moon first unless the idea is to use resources on the moon to construct the bastard. And if there's one thing we learned from the Apollo and subsequent robotic missions, it's that there's fuck all on the moon that's useful. The mass of the refining equipment we'd have to lug over there would be far in excess of any energy saving we'd gain from a moon launch.
No, if the idea is to build an interplanetary spacecraft, the only way I see that being feasible is to construct a ship in orbit. Something like the ISS, but with engines.

That was Von Braun's dream before the Apollo Officials abandoned the Earth-Orbit Rendezvous in favor of the Lunar Orbit model. The space shuttle program, if it had been as successful as it was conceived to be, would have already made such a goal feasible. Unfortunately, the plan of having 50 missions per year with a reusable space shuttle lived up to a tenth of that goal.
SlyReaper wrote:The new heavy launcher NASA are building should do the job, lofting ~70 tonnes of payload per launch. Like I said, we already know we can do it because we built the ISS, and Mir and Skylab before that. All we need to do is apply those same principles, and add an engine module, some fuel tanks, and lay out the whole thing so as to be able to survive the acceleration from the engines.
Uncle Sherm wrote:How far has our Rocket Technology come? How would a Falcon 9 Heavy compare to the Saturn V in terms of power and efficiency? How much farther do we need to go before we can contemplate a manned mission to another planet? All questions that can be answered by a real organized effort to go to the moon.

It's an order of magnitude cheaper, and that could come down even further if they can manage to recover their spent stages for reuse, as they have planned.

I don't even see this one, really. By first approximation, space is hell. What kind of disaster could possibly make Earth worse to live on than the rest of the solar system already is? Even the dinosaur-killing meteorite left Earth with a breathable atmosphere, moderate temperatures, plenty of water, radiation shielding, etc. Indistinguishable from paradise, compared to any place off-planet.

You can't compare the costs of a proven rocket with one that is, at the time of writing, still fictional. Paper projects *always* come out cheaper! Even if SpaceX can deliver everything it promises, on time and on budget - which historically, it hasn't been able to - Falcon Heavy is a considerably smaller rocket than Saturn V.
EdgePenguin wrote:Or for that matter, Long March 9.
If we are going to be comparing launch systems that haven't flown yet, look at what the Chinese are doing. With Long March 5 and its derivatives close to flying, they are looking to the next step - which is a super heavy lift rocket. Incidentally, I think the LM-5 is capable of putting a Shenzhou capsule on a free return trajectory around the Moon on its own, and should be flying by 2014. If the Chinese choose to race, they would have a good shot at being able to send a person around the Moon before Falcon Heavy is ready to do the same, and could well have LM-9 ready before the only comparable launch system in development, the SLS, is available.
Soralin wrote:True, but the Falcon Heavy isn't really that far off from being launched. I mean, They've launched a few Falcon 9's and those have costs around $50m or so I think, and a Falcon Heavy is basically a Falcon 9, with 2 additional Falcon 9's strapped to the sides of it (the first stages of them at least), and a crossfeed system. So there's not a whole lot of extra stuff or changes in manufacturing that need to be done to make it work. And yeah, you do need 3 of them or so to beat the Saturn V for lifting capacity, but it's still looking quite good in terms of $/kg.
[/quote]Yeah, looking at the stats, it looks like Long March 5, or at least the larger variants of it, could do that. Although a Delta IV Heavy should be capable of doing that too. And there actually is a planned launch of Orion on a Delta IV Heavy in 2014, but Orion is quite a bit heavier, and so you'd probably need more than that to lob it around the moon. Falcon Heavy is planned to launch a year earlier, and their Dragon capsule was already designed to be able to handle atmospheric re-entry from a lunar return. Although SpaceX would presumably need someone to provide funding for such a mission to them, so having the capability of doing so, and actually doing so, are two different matters there. But yeah, China has definitely been making good progress with its rocketry
EdgePenguin wrote:I can't imagine there being political will in the US to do it quickly. Delta IV/Orion is I think simply a high altitude Earth orbit, not a shot around the Moon. It will test if Orion can handle re-entry from interplanetary missions. Falcon Heavy probably won't be called upon, as NASA seems to like SLS for this mission, with the aim of doing it in 2019.

As another poster asked, "what can it hurt?". It can hurt money. Money we could be using to protect our environment so we don't destroy the only sustainable place for human life we're likely to realize in our existence. Money can save lives. Quite frankly, it "hurts" lives. To put it bluntly, you kill people by sending Edgear Mitchell to the moon.
Compare the amount of money it costs to launch 100 rockets with the amount of money it takes to invade and occupy 1 country, or bail out 1 bank. Then tell me it costs a lot of money to send people to the moon.

Seriously, the Apollo program cost significantly more than, for example, the first Gulf War and the RBS bailout combined, with none of the upsides.

Well, it wouldn't necessarily have to be funded by NASA.A number of people paid like $20 million to visit the ISS, and the Dragon can fit 7 (although that might get a bit crowded on a long flight). I'm sure there are a few people out there who would be willing and able to pay for a trip around the moon.

How do you propose to make those leaps of technological progress without actually investing in said technology?
Puppyclaws wrote:Well since I don't believe in magic, I don't think it's possible for those leaps of technological progress to happen. I'm pretty sure we are not going to get past the problem of limited resources. So I am not interested in throwing money in that particular black hole, so to speak.
Ghostbear wrote:The costs for Apollo include all R&D spending in them, even though it included a lot of developments that were useful outside of the mission (integrated circuits, fuel cells, rocket technology advances, etc.),
Think of how amazingly useful satellites are in the modern world, yet they might as well have started off as orbiting trophy stands.

Even with things not be based directly on that technology doesn't really mean that it didn't contribute to the advancement of that technology. Sure, they might have abandoned RTL* and the Saturn launchers, but that doesn't prevent other technology families from incorporating the lessons learned with them. From my quick reading, it would seem to me that the requirements of the Apollo missions meant that Saturn was a poor fit for a general purpose rocket, but they still would have learned more about rocketry in general while designing it. You would expect the same with integrated circuits; a lot of knowledge there might have been RTL specific, but there would also be a lot learned that could be applied to ICs in general. It wouldn't be implausible to me to think that they might have decided, in part, on what to switch to afterwards based on their experiences with trying to make RTL work as an IC.
Zamfir wrote:But they didnt develop those things afterwards with the lessons incorporated. They partially even predate Apollo. TTL was developed for air-to-air missiles in the early 1960s, then became big with the cheap 7400 stuff from Texas Instruments. At that time, the Apollo computer was still under development.
