mattnyc99 writes "There's a serious feud brewing this week over the Bush administration's plan for a manned mission to the Moon as an eventual stepping stone to Mars. The Planetary Society, a top group of former mission managers, space-based scientists and NASA astronauts argues, is set to rebuke the Moon plan at a conference next month in favor of hopskotching an asteroid on the way to the Red Planet. Agency chief Michael Griffin issued an abnormally strong response to the society, calling it an overly political criticism of Bush for a plan that he says was 'the best legislative guidance NASA has ever had.' Either way, it's clear that the stars are aligning for the whole space race to be reconsidered as a new administration steps into the White House. So far Clinton and Obama (who just added his) are the only contenders with space proposals."

Why Space Exploration Is Worth the Cost 276 comments
mlimber writes "The Freakonomics blog has a post in which they asked six knowledgeable people, Is space exploration is worth the public cost? Their answers are generally in the affirmative and illuminating. For example David M. Livingston, host of The Space Show, said: 'Businesses were started and are now meeting payrolls, paying taxes, and sustaining economic growth because the founder was inspired by the early days of the manned space program, often decades after the program ended! This type of inspiration and motivation seems unique to the manned space program and, of late, to some of our robotic space missions.'"

Asteroid Missions May Replace Lunar Base Plans 237 comments
An anonymous reader alerts us to a story about efforts to modify the United States' space exploration plans to focus on asteroid missions rather than a lunar base. Scientists, astronauts, and former NASA division directors will be meeting next month to develop an alternative to the Bush administration's Vision for Space Exploration. We have previously discussed the possibility of a manned asteroid mission. Quoting:
"Numerous planetary managers told Aviation Week & Space Technology they now fear a manned Moon base and even shorter sorties to the Moon will bog down the space program for decades and inhibit, rather than facilitate, manned Mars operations--the ultimate goal of both the Bush and alternative visions. The first lunar sortie would be flown by about 2020 under the Bush plan. If alternative-vision planners have their way, the mission could instead be flown to an asteroid in about 2025."

I am very convinced that if some of the leading candidates get in with all their promises of health care and expanded benefits there won't be any money for NASA to do something big. It will simply fall by the way side because it simply doesn't get Congressmen or Presidents votes.
The best thing has already been done, the hard choice has already been made, axing the shuttle. Hopefully that expense relief won't be taken from NASA but I fear it will. Without the costly expenditures needed the money will probably go elsewhere.
If the main opposition is truly because "BUSH" wanted it then it speaks volumes for just how juvenile the opponents have become. We need a direction, it has to come from the Administration, as Congress no longer attempts to lead anywhere but schemes to keep themselves perpetually in office. NASA has been wandering, stuck with two spruce gooses. The shuttle and ISS. The ISS could flourish without the shuttle and we can hope it will. Yet I am very sure that with all the promises being made by candidates that NASA is the least of their concerns. We are seeing the greatest promised expansion of Federal power over our lives and people are cheering it on as if it were the latest American Idol contest.

The main opposition is because Bush wanted it, and then didn't fund it. He wants a positive legacy (since his *ahem* other legacy isn't looking so hot), but he didn't want to spend any of the political capital necessary to actually do it. It's like his suddenly trying to jump start the Middle East Peace Plan he'd been ignoring for 7 years, only here it's even easier to just "mandate" that it be done without doing anything substantive to accomplish it. He gets to seem like a visionary in the present, and if it somehow ever happens he can claim credit, and if not, nobody will remember that niggling detail of his Presidency anyway.
Bush's "Mars, Bitches!" plan, and resulting budget problems since now NASA had a huge new project to worry about and no additional money to do it with, was one of the factors that directly contributed to the scrapping of any Hubble repair mission.
You want to talk about generating enthusiasm? The continued operation of Hubble would generate ten times more interest than a moon/mars plan that in the most optimistic thinking of a hypothetical plan by a guy who had no intention of being around to see any of it turned into reality isn't going to do anything for a decade.

Second, your concept of the middle east peace process seems to mimic a headline news blurb. Bush and his administration has been working for middle east peace since the start of his first term. It wasn't until recently that he actually took a trip there outside of US military bases and war zones.
You can argue not enough or soon enough, or a combination of both and be correct. But claiming he didn't care or didn't find is a little disingenuous. It may seem like that to you if your mostly paying attention to headline news and the sorts (some call it the drive by media) so I can understand the position.You mean the arguments about being risky and so on were a bunch of lies? Tell me, what costs has NASA created that has zapped up close to 12 billion dollars in less then 3 years without producing a vehicle yet? Last I head NASA wasn't in the habit of waisting money or am I wrong about that? Oh yea, I remember now, NASA has been ignoring the budget redirections and Congress has been earmarking portions of the funding and spending the money on anything they damn well pleased which caused the hubbub about Bush re-redirecting funds about a year or so ago. Hardly a problem because of lack of funding, Maybe lack of oversight of congress pilfering for their contributers and rogue NASA officials.
I'm actually surprised that your even blaming this on Bush too. It seems that the democrats are the ones wanting to cut NASA's budget. They wanted to pull 500 million so they could 1.3 billion to the global AIDS fund. Instead, they ended up placing the 2007 funding at 2006 levels. I think they are just as hard if not harder on NASA then any republican congress. It all depends on who's contractors are donating money and who is in power at the time I guess. This seems hardly a one sided issue though.Isn't there a repair mission already scheduled for the Hubble? I think it is slated for 2008 and will replace the batteries, gyroscopes, a spectrograph, and the main camera which should put it back in operation until at least 2013.

1) There is very little technical overlap in designs between a lunar and martian based program. The Moon has no atmosphere. That means no atmospheric braking. A lander landing on the Moon is radically different than one landing on Mars since the lunar one has to use only rockets to slow its descent. The Martian one can use rockets and parachutes as well as glide. Also, the lack of an atmosphere means that the Moon can not as easily provide oxygen or fuel as Mars, where those products can be pulled directly from the atmosphere. The Moon requires regolith mining to obtain any materials.
2) The transfer vehicle to the Moon is going to be able to complete the trip within 120 hours, or 240 hours if you have to do a return. That is easily within the range of not needing to recycle. You can just load up with consumables and then replenish at either end of the trip. The Martian vehicle will have to have some pretty hefty recycling technology.
3) The day/night cycle on the Moon is vastly longer than that of Mars. Mars is pretty close to that of Earth. Solar power is not even remotely practical on the Moon. (Except in the polar regions where it s theorized that would be possible to find spots where you have continual daylight). If you want to go somewhere other than the poles on the Moon for any duration, you are looking at needing a new generation of nuclear power. Which would also be useful on Mars, but there is a tradeoff there in terms of mass and other factors.)
4) I am back to "There is no atmosphere on the Moon" because it keeps impacting multiple areas. One of the problems that needs to be solved is HVAC type issues. Keeping things warm or cold. The Moon has no atmosphere, hence no convective heat transfer. All heat transfer is radiative or conductive. That necessitates a completely different thermodynamic paradigm than would be possible on Mars.
5) In terms of Human factors, the Moon is 1/6th gravity and Mars is 1/3th. That means items on Mars weighs twice as much as that on the Moon. The lunar space suits can not be worn on Mars as they are too heavy. New ones need to be designed. (We're also back to "The Moon has no atmosphere". Space suits need to be able to maintain a steady temperature inside. Since a lunar space suit is essentially a thermos when you consider it is in vacuum, all you have to worry about it shedding excess heat. On Mars, you are essentially enveloped by a fluid - the atmosphere - which has a temperature and can carry away excess heat.)
Actually, the reason for the asteroid mission instead of the lunar one is simple. It will require essentially the same type of spaceship that is required to get to Mars. The lunar base only has about 20% overlap with Mars technologies and - honestly - for those 20%, Earth is as good an analog as the Moon. When you develop a technology to go to the Moon, that is what you are developing. You are not developing one for Mars.
Essentially, you get the Moon and Mars for only twice the amount as getting the Moon or Mars.

Re:Objections (Score:5, Insightful)
OK, you've listed all the non-advantages for a moon program. Now how about some advantages?
1) by developing technologies for hard vacuum, you are in a sense prepping for one of the hardest parts of the Mars mission, that is, a months/years long transit time. You have a nearly perfect platform for testing technologies outside of the Van Allen belt(s), exposing them for long durations to solar heating and occluded cooling. Note: developing the tech for an asteroid mission is essentially saying that 'we can already do this part' - can we? Reliably to put a crew's lives at risk over extended periods of time?
2) long-term value: geopolitical, military, commercial, geographic - as you dismissively point out, there are theoretically (only!) 2 places where solar power access is continual. Possibly more importantly these two places (the poles) are also the only places where the sun, the earth, in fact the entire ecliptic (north or south) is in clear line of sight. How much are those two spots worth today? How much will they be worth in a century? Want to surveil deep space while having a straight line-of-sight link to earth? Want to have a launch point for a flinger that could theoretically put lunar materials anywhere in the earth-moon system with the simplest ballistic solution? I'd argue that being the first with a permanent base there has an INCALCULABLE value over longer timespans. And if you have the first base on one pole, it's not a giant stretch to put a second one on the other pole and monopolize both. The lunar poles - for near-earth space - are practically 21st Century Suez or Panama canals in their strategic value.
3) raw materials: again, a lunar base in the longer term answers one of the bigger questions to space exploitation. Tossing something up to an orbiting factory or processor module is trivial from the moon, and the effectively limitless raw material (including rather important oxides) doesn't hurt. Going to an asteroid lets you explore, but bringing that back where it could be usefully exploited is an ENTIRELY larger project with propulsive technologies we aren't even CLOSE to having.
Personally, if I were looking at it as a game of Civ or something, I'd say the asteroid is probably the cheaper, higher payoff short range program. The lunar base is the more expensive, slower-to-develop programs that ends up being the incontestable game-winning economic- and military-power multiplier in the endgame.
Needless to say, I don't see nearly the value you do in an asteroid mission. I see THAT as the 'flash in the pan' while the idea of a lunar base is the investment-growth option, for Mars certainly, but also for decades if not centuries further on.

What else, pray tell, did you think was going to be our motivation? Altruism? The beautiful view?
Organisms, including those that fly spaceships and use computers, compete with other organisms for resources. It's a zero-sum game. Those who compete best win, and are able to then pass some advantage to their children to give them a leg up in their own competition. Securing any advantage is good, securing that advantage while denying it to your competitors is logically BETTER.
Either program - lunar or asteroidal - is going to cost hundreds of billions of dollars. Now, those dollars could be spent on many other things that are beneficial to our people or yes, our country. When deciding where to spend those dollars, I bloody well HOPE that someone is doing some sort of cost-benefit-time analysis. And if those dollars can be spent giving us something that is an advantage to us in terms of commercial, scientific or even - shudder to think of it! - military, doesn't it stand to reason that's worth pursuing?
Unless of course you're one of those starry-eyed Utopians who believe that somehow we're gong to evolve into a future where people don't compete? Then you're simply irrelevant to the conversation, because if that's the case, there's no reason to spend the resources on space exploration in the first place when there are so many other pressing immediate human needs here on earth.

The whole national obsession with the space program drove the interest in science which bootstrapped a generation of scientists and engineers. It was not space per se that did this, but the obsession that saw Apollo models hanging from the ceiling in every second kid's bedroom.

At least part of that position was stated to be that a manned Mars mission could be a cooperative effort between the US and the Soviet Union. i.e. A political goal. That's an aspect that doesn't apply quite so much now.
Also, at that time, the Planetary Society was a lot less keen on manned missions than robotic ones. Friedman, Murry and Sagan (the notable founders) were all veterans of the highly successful unmanned planetary probe missions. They tended to view the manned program as a very expensive method that tended to take money away from the robotic probes.
Others disagreed with this viewpoint. The National Space Society, for example, (also populated with former astronauts and space scientists though no one as much of a household name as Sagan) tended to take a more pro manned space viewpoint.
