Requiem for the Once-Imagined Future 674
Carl Bialik from the WSJ writes "The underwhelming Discovery mission has the Wall Street Journal Online's Real Time columnists lamenting the space program's failure to realize the sort of intergalactic exploration they once imagined as kids through the works of Arthur C. Clarke and Robert Heinlein. Considering the Viking landers were digging around Martain soil back in 1976, 'we figured the place would be necklaced with orbiters and cris-crossed by rovers by now. Maybe there'd even be astronauts (or cosmonauts or taikonauts) tracing the courses of unimaginably ancient rivers.' Instead, we get a mission whose highlights were 'a) it came back; and b) an astronaut pulled bits of cloth out from between tiles.' At this rate, the columnists fear the innovations of the future won't be much more exciting: 'Maybe Real Time 2030 will fret about how our college kids do little more than steal full-res holographic porn when they're not getting their financial identities stolen by cyber-jihadists eager to build more backpack nukes.'"

For the most part, supply and demand takes care of that, so we don't really need a separate energy budget. As energy gets scarcer, the price rises and we use less of it in order to stay within our financial budget. When the electric bill starts to hurt, you start remembering to turn off your lights.
The main problem is that technological development is sufficiently slow that it tends to lag behind need. By the time the price of oil and gas is high enough to encourage investment in development of alternative energy sources, we can't wait another ten or twenty years for the technology to mature. So we have to be investing in basic energy research all along, and building the infrastructure a bit before it is really cost-effective.

It is misleading to extrapolate short term price fluctuations, which tend to reflect global politics and production quotas more than actual oil and gas reserves. In any case, the cost of fuels will not rise indefinitely, because eventually they will become competitive with fuels produced by renewable energy sources, and price will plateau. An additional source of energy in the medium term is likely to be nuclear power, because with newer reactor designs, and greater awareness of the environmental damage from combustible fuels, the hazards of nuclear power no longer look quite so daunting.

Those wackos are extreme examples, granted, but it seems like they're also symptomatic of larger societal problems.
I'm ready to pick up and keep moving, though, and I think a lot of people of my generation are. We never saw a moon landing; it happened before we were born and, frankly, even if we went back it would seem like old hat. "Yeah, Earthrise. Great, never seen that before". We read about this shit in the *history* books, man. But that's not a bad thing: I suspect a lot of us wouldn't find the concept of, say, mining asteroids as exotic as the Boomers would, and maybe that's all we really need. And hey, if that's possible, if that improves our lot, maybe it'll finally be that human advance where, once it starts, it just continues on and on.
Of course, speaking of the Boomers, I fear that my generation (I'm 28) might be one of those unlucky historical examples of one which didn't get to do jack shit because they were so busy catering to the needs of their wealthy elders while trying to patch up the disasterous debts they left us.

The biggest problem would be mustering the needed level of international cooperation. No doubt the cost of the program would be too much for even the richest nations to go it alone. How many years would go by before enough nations could get together and decide on a plan of action? What would the USA do if 20 years down the road more accurate estimates of the impact point proved that the asteroid was going to impact on the other side of the globe? Would the USA withdraw its participation? I'd like to think not but I've lost much of my faith in American largess. Anyway, balancing an enormous economic drain versus the morality of allowing a serious disaster to occur to someone else (possibly an enemy) would be a serious quandary for any nation.
The problems are certainly surmountable; in theory. The world's track record regarding other crises is spotty at best. How much progress have we made at:
eliminating controllable diseases,
controlling global population growth,
controlling greenhouse gas emissions?
The list goes on and doesn't even address the more important but tougher issues like war and poverty. I'm sure someone will come up with a good example where the world got together and solved a problem but overall history shows little that it's rare and difficult.

Perhaps he wants more capable rovers (ignoring that the current ones gave us a treasure trove of info)? Then don't divert money into manned spaceflight, which is incredibly expensive. Even as is, it won't be long before we get to see Mars Science Laboratory on the Red Planet - a rover the size of an SUV which can take drive around, take core samples, do complete isotopic and minerological determination of samples, and even burn coatings off a rock with a laser from a distance to do spectral analysis.
Speaking of manned spaceflight, his desire to have people trudging over the red planet ignores one sad, but true fact: chemical energy density isn't getting any better. We somewhat peaked out on fuel potentials in the 1960s. Now, there have been small improvements - for example, strained-ring hydrocarbons may replace kerosene - and there are some interesting "high ISP/high density" fuels that they're trying to stabilize (such as alane - stabilized aluminum hydride); however, the sky is not the limit as far as fuel density goes. And, as chemical fuels look to be our way of getting off the planet any time soon...
So, what can we advance, as far as getting payload off the Earth is concerned? We've improved engines, but there's only so much performance that improved heat management and refined shapes will get you. We can advance materials, but while we have some great "potential" materials on the horizon (such as nanotube composites and CVD diamond), and superalloys have been coming down in price, we're not the leaps-and-bounds beyond top-tech 1960s materials that would help.
So, in short, lugging payloads into space on disposable rockets remains expensive. Reusables were supposed to change this, as fuel is cheap; however, at least our first-gen reusable had serious maintenance problems (will a next-gen reusable be better? We'll have to wait and see).
This is simply the problems on getting large payloads off of Earth. Getting humans to Mars and back safely requires a complex system of precursor missions, engine and power plant development, habitation R&D, lots and lots of shielding research (the "bremsstrahlung issue" from GCR still hasn't been solved), getting reliable long-term use versions of *almost all* of the things that keep breaking on ISS (oxygen generation, water reuse, spin stabilization, etc - you can't just ship up a new one), "large mars entry craft" development (the atmosphere is nothing like ours, and we've only dropped in small craft, which are easier to deal with), dust handling (Mars dust is particularly nasty, with its electrostatic potential and tiny grain size), return fuel generation (optional), and dozens of other issues that the Apollo astronauts never had to deal with.
In short, the Mars mission is much more complex than Apollo, and yet, our rocket technology, bound by physical constraints and the requisite constraints of a spiral development process, has not come that far. Hence, the cost is high, the immediate payback low, and thus securing funding for it has, to this date, not occurred. It's not a difficult thing to understand. Meanwhile, our various robotic probes and telescopes keep dumping back copious amounts of valuable data to Earth, while tech keeps on advancing at its "slow and steady" pace.

Eastern Europe was *devastated* by World War II, and was under the control of the Soviet Union for much of the Cold War. The result being that the area never truly recovered from the war and only now under the European Union is seeing any progress. Western Europe was also badly damaged, but had many important advantages: it had the United States to bolster its regrowth, and the population loss wasn't as great as in the East.

Yes, there are going to be circumstances beyond each of some individuals' control, and you can be born to parents that simply don't care whether or not you grow up into a someone who can feed herself. But to the extent that we do put resources into helping out people in those situations, we're not excluding doing the more magnificent things of which we, as a species and especially as an adventuresome culture, are capable.
I usually try to avoid politics and social debates
And, given the breathtakingly adolescent tone saturating most of those conversations (especially on slashdot) I can hardly blame you, but none of the cool nerdy stuff we love happens in a vacuum. Without weaving it into the wider cultural landscape (and the resources therein), the cool nerdy stuff would barely escape a handful of college labs. So fans of all things nerdly need to truly understand the larger societal and politcal contexts in which technology gets funded, used, praised, villified, and considered (too often) mutually exclusive with warmer, fuzzier "humanities" issues.
If you haven't noticed, though, I'd consider the progress of technology on all fronts to be the single greatest contributor to the conditions in which the potentially "hungry" live in the US. By conditions, I mean, as opposed to, say, that of those poor bastards in Niger, literally dropping dead from lack of food. In the US, you pretty much cannot drop dead from lack of food unless you want to, or are so addled/sick that you can't grasp what's being offered to you. Every city in the country at least has a place to obtain a meal for those that ask, and it's only through even grander technological feats that we polish the efficiencies and productivity that make that largess possible.
Besides, it's not like the money spent on space programs is actually packed up in boxes and launched into space. It mostly pays people, all of whom themselves buy houses, hire carpenters, rent videos, take the occasional vacation. Certainly some of their effort, put solely into making, say, an MRI machine so cheap and safe that we wouldn't think twice about using it on everyone with a sniffle, insurance or not, might lower the cost of health care a touch. But for that to happen meaningfully, we've got to take the lawyers out of healthcare first. It's not the lack of healthcare for a family that's really horrible, it's the fact that a lawsuit over someone else's test regimine, or the insistence on the use of fantastically costly drugs can burn up more "healthcare dollars" for one family than basic good care for 50 families would otherwise cost.
Of course, if everyone who owns a Bentley were to sell them, buy a Scion, and use the extra cash to buy 40 Scions for other people, there'd be less complaining about car ownership, either. But we're not a culture that prohibits the Bentley-ables from celebrating their prowess at basketball, charisma as an actor, insight at founding Google, or willingness to risk a lot on commercial space ventures, and nor should we be.

Of course, I'm overshooting the topic at hand (Mars), but this is the undercurrent beneath our greatly protracted exploration of our environment. Complicating the fact is that Mars appears to be an essentially dead planet, in which case it's difficult to get people to pay attention when you want to spend (from their perspective) a billion dollars to study rocks on another planet. There is no real, juicy carrot at the end of the stick.
Meanwhile, our future is mapped by Asimov, Bester, Heinlein, Stephen Baxter, et al... most of whom were scientists. So I find myself amused at their dismissal of the soft sciences, from which I believe they could have drawn some temperament. There's just no way, in my opinion, that the human race is going to spread its wings just because it can. Perhaps I'm overly cynical, but I don't think we'll get our asses of this rock until we've almost completely ruined it. And by then, it may be too late.
Because in our community, we take intelligence for granted. No, we really do. How many times a day do you find yourself extremely aggravated at the sum of stupidity you deal with on a daily basis? That's because you're encountering the general public, which on the whole is a pretty average bunch of people. But it is this group that holds the reins of the future, for better or worse, primarily through the buying decisions they make and how they choose to conserve, either through recycling or not leaving the tap on when they brush their teeth.

Oh but we'll have to go up there and it'll take forever to build! No it won't. Robots, people! I remember reading in Discover around 1992-93 or so about a new all-electrical process someone had developed for extracting materials from sand. He had a bunch of little robots running around the desert building solar cells out of the raw silicon. The moon's got that in spades, and aluminum for the connections. Yeah the efficiency won't be great but who cares when you have an entire MOON (or even half a moon) of them?
How do we get the robots there? Send some. But it won't be enough! Self-replicating. Is this really such a hard challenge? We're seeing basic steps towards it today. Tell me it would cost more than a major space program like a Mars trip to get it working and on the backside of the moon.
How does the power get back? "Laser". But won't it cook the earth? Not if you lock the depression angle so it can only hit geosynchronous orbit and not cross the earth.
But won't people abuse it and fight over it? Declare the moon array itself public domain. Make all the receiving sattelites privatized to create competition and prevent government death rays. Make all the ground stations government owned to prevent slum-shopping for placements by over-greedy immoral corporations. There, you have a case for competition and a nice construction project for all those 3rd world equator countries with the best views of orbit.

Point the lasers the other way and use them with sails or to power ion drive systems. We'd be mining the asteroid belt with Mark 2 replicating robots in no time. Then we have unlimited energy AND unlimited resources.

With virtually free power, post-problem pollution fixes are cheap enough to work. Want to educate everyone? What kind of network can you run when you don't need to worry about electrical losses? Want to cure cancer? There's some promising work with antimatter. Build accelerators to produce it, more efficient ones than the general-purpose kind we have now. Don't want them on earth? Put them on the moon too, make a bigass one around the equator, ship the people there on vacation. Want to get rid of that threatening asteroid headed for earth? Zap it with a petawatt or two before it passes Mars and watch the vapor pressure push it away. Maybe into a nice orbit where we can strip mine it.

The worse case is that we continue what we've been doing with the shuttle program -- funding enough to keep our manned space flight program treading water, but not enough to make real progress.
Better to phase out the manned program as our ISS commitments wind down, than to spend just enough money to maintain a stagnant program. Stagnation is a waste of time, and dangerous.
