NASA Priorities Out of Whack?
amerinese writes "Just last week, we saw a story on NASA reconsidering the fate of the DAWN mission, another reminder of the space agency's budget woes. Gregg Easterbrook over at Slate.com argues not only is the budget a little short, but NASA's priorities are all wrong. From the article: 'For at least a decade, it's been clear that the space shuttle program is a clunker. Nonetheless, NASA's funding remains heavy on the shuttle and the space station, while usually slighting science. This year's proposed budget for fiscal 2007 takes the cosmic cake.' Is NASA just not thinking creatively enough?"
It.....*is* Google...?
By now you should have guessed...I'm your magic negro.
Whilst I agree with the vast majority of this article, the planet finder project should be given a much higher budget, study of the earth should have a much higher priority, I think the author leaves the Near Earth Object study a little low on the list, I would think this should be at least number 2 on the list of priorities, first save the Earth from itself the study of moisture is important so this is fine, second save the Earth from a huge chunk of rock eliminating mankind, from there on down yes cool study other object in our solar system, study possible locations for other life out there.
Additionally I am not sure about the moonbase, until we get a definitive answer on the question of if water exists on the moon I don't see the point in building a base there, really we should be putting a lot more focus on studying the moon, what rare minerals can we find, is there any water anywhere that can be used to fuel spacecraft travelling further than the moon. These questions can all be answered with probes and possibly robotic landers we should be putting more effort into studying in this way before we even consider sending people back let alone building a base there.
I am interested in the study of the universe, I am curious about development of galaxies and black holes but I am more interested in protecting our species from an extinction level event either from us damaging the planet or from an asteroid wiping us out. It seems like NASA is really just trying to get popular support here. For the unknowing masses building a moonbase would seen really impressive, having mankind walk on the moon again would be a great advertisment for NASA, "hey look guys we still got it". Given the set backs they have experienced in recent years I can kinda understand their reasoning to feel like they need the public behind them again, but I think a report saying we have found a way to save the Earth would be a lot better for their publicity than a report saying we have some guys bringing more rocks back from the moon.

Cue the Get some priorities! trolls. :)
I'm not surprised, although I think they still manage to be more fiscally responsible and sensible than the rest of the US government as a whole. Barring the money sink that is the space shuttle and international space station (why do we still need this? Oh yeah, politics), they've had really successful projects. Just take the recent Mars rovers for a high-profile example.
Big things like rockets, airplanes, and space stations are popular with Bush's friends. Bush doesn't care about science, it's just for show to drum up political support.
How many probes could we launch with all that money? We could have probes flying all over the solar system. We could have fundamental research into remote robotics.
I've always thought that NASA should have a program that produces three types of probes, small, medium and large. And they should be modular, such that you can plug in all sorts of different sensors that use a standardized design.
There is no reason that through mass production, NASA couldn't be launching thousands of probes a year. If you're launching that many, they don't have to perfect. Launch 10 of them at every target, hoping five will end up working.
NASA needs to completely change their culture and use some intelligence for a change.
Sometimes it's best to just let stupid people be stupid.
It's what's sexy.
Climate research is not sexy. A manned moon base, a la Space 1999 is sexy.
Deep space exploration via robotic probe is not sexy. A mission to Mars, a la...well..Mission to Mars, is sexy.
If NASA wants any funding at all, it has to portray what it does as sexy. Little wonder that manned moon bases and missions to Mars are what they're trying to sell, regardless of the actual feasability of either goal.

People see shuttle launches on TV. And most will, at least, not protest the money being spent. But they might get pissy about billions vanishing into a black hole of government science whose results they cannot watch on TV. NASA's prioritization is, at least to some small degree, a slave to public opinion. Yet another reason why privitization of the emerging space industries will be helpful. Then, at least, informed people with money can set priorities as opposed to politicians who just want to get elected.
"I have never won a debate with an ignorant person." -Ali ibn Abi Talib
to know, as Mr. Easterbrook appears not to, that you do what the military tells you to do. Then tell the media whatever the hell you want.
The shuttle and space station don't help us get to the moon. The planned CEV is more of a step back to the Apollo designs. I think it is a simple matter that realigning the budget away from the shuttle and space station is admitting that the last couple of decades at NASA has been a waste, and they just can't bring themselves to admit that.
Thank goodness the folks at Slate have a better understanding of NASA's purpose than I do: I have a hard time figuring out where "environmental and climate research" is derived fomr "the National Aeuronautics and Space Administration." But then again, I've always been bad at figuring out acronyms.
TANSTAAFL
Here's an experiment: Find out what state NASAs big dollar items come from. Then look at who is on the committe that controls the NASA budget and what state they are from. Look for correlations. After that, we can talk about priorities at NASA.
If a bunch of engineers and hard scientists got together and decided how to spend NASA's budget most effectively, we'd see only automated missions. The data gathered would be wonderful, it would be efficient, and their budget would be cut in half the next year by Congress.
Manned exploration is the sizzle that sells the steak. You have to keep a manned program going to keep the short-attention-spanned taxpaying pinheads interested in space. If space is just drones and bots flying off to take soil samples and collect space dust, the money will get diverted to a subsidy to study how pet monkeys could be used to deliver nuclear warheads to a target or some other stupid Pentagon project.

Why spend all that time and treasure putting telescopes so far from humans and then spend even more time and treasure putting humans RIGHT NEXT to the damned things?
... sure, vibrations and dust are natural events there, but humans add more.
If you think having telescopes on the far side is good because it is out of the way of human pollution, then why for heaven's sake do you want to throw human pollution back into the mix as close as that?
The vibrations from human equipment, outgassing, dust raised
Good god almighty.
Robots would have to do 99.999% of the work anyway. What would humans add to either the construction or maintenance?

Nasa was never about science. It was about putting people on the moon. The science talk is just a nicer lofty goal that hides the real goal: making sure nobody gets control of the moon other than the US.
If you control the moon, you have a major military strategic advantage, the ultimate high ground. You can catapult anything down, anywhere on Earth and nobody can stop you. So NASA's highest priority is making sure nobody gets ahead of the US on this technology.
Science has always been secondary. That was true during Apollo, that's still true now.
One of the arguments given for completing the ISS is that other nations have contributed to it, and it would not be in good faith for the US to stop working on it.
How much for us to just buy them out? I suspect much less than the cost of completeing it.
While there are points to be made about how the shuttle is a bad choice for space flight and science isn't getting the funding that's needed, this author clearly doesn't understand all the benefits of manned space flight. I mean seriously, saying that the moon is only interesting to geology postdocs? That all people do in space is to take each other's blood pressure? He clearly lacks ANY knowledge of the science and innovations we gain by reaching new frontiers. One of his references is to a radical writer's article that thinks Apollo missions stopped off it orbit before going on to the moon and fails to understand the concepts of where to get fuel, where to stage equipment and where to practice somewhere relatively close by. Now, not only are blogs spewing crap but "news" sites are too.
One can easily argue our national priorities are considerably out of whack. Easterbrook argues there are better places to spend the money than the projects which have been proposed. He might be right. But it's easy to argue that the proposed projects do have value.
A moon base might not help Mars exploration. But a moon base can begin the process of using lunar resources to support both exploration and human needs on earth. There's more to space than scientific exploration.
The James Webb Space Telescope might focus on the distant universe and questions of esoteric value. Planet finding, on the other hand, will have little real impact on humanity as well, at least in the near future. Both projects do have worth, however.
Of greater interest to me is comparing NASA funding to other things our society does. Back in October the Washington Post proposed canceling Bush's Vision for Space Exploration, and cited the need for health care for poor children as a worthier alternative. What few people recognize is that health care spending in the U.S. is 100 times the NASA budget. Health care spending is also increasing annually at multiples of the NASA budget. If poor children aren't getting decent health care, that's the fault of the health care industry, not NASA.
NASA, while far from perfect, does appear to be struggling to improve and is making some progress towards that end. It would be nice if other American activities -- for example education -- showed the same kind of work at improvement.

Unfortunately what I mean by popular backing is influencial Senators and Congress men protecting jobs and investment in several sites all over the country. Lean mean, robotic science projects don't generate this kind of big permenent infrastructure which drives it's own lobby in Washington.
A shuttle launch costs $1B in new costs. That's not including any share of past, paid-for, R&D. That's staff, expendable tank, refurbishing the solid boosters and shuttle engines, fuel, etc.
The Deep Impact mission (which smacked into a comet so we could analyze the dust) and the Stardust mission (which return fabulous samples of comet dust) together cost $600M or $700M complete. You could no doubt find a similar mission to bring it to an even $1B.
This is not counting any share of the cost of failed probes or failed shuttles.
Which do you think returned more bang for the buck?

That's a recent, but not the most egregious case of near-sighted budget failures within NASA. All the science programs are being gutted, despite them having been the most successful and cost effective programs in the current space sector. Dawn stood out because it would have returned a mere $30 million to the coffers, the bulk of the $370 million budgeted for the mission having already been spent. Obviously you have to get your $30 millions here and there if you want to save a few billion to increase spending for the manned spaceflight program, however, it looked farcical to throw away $340 million already spent and a mission within months of launch in order to get that particular $30 million.
Dawn may have stood out in that regard as an obvious budgetary foul-up, but its indicative of a culture within NASA of administration that appears to be pandering to the short-term will of elected politicians rather than medium to long term human goals. There's necessity there of course, in that the survival of much of the public science in NASA is in the hands of the politicans, but we currently appear to be throwing the baby out with the bath water. When you cancel a science program, you not only lose the science that you fought to get funding for, but you send a message back to the bean counters that they spent however many billions of dollars on projects that never came to fruition. If you want to build central governmant distrust of science funding, this is a good way to do it.
You can't launch and repair secret spy satellites with a space probe. That's why the Shuttle will continue until there's a replacement.

After all, people forget that NASA's height of popularity was when we were bogged down in an endless pointless war that we were losing, as the nation went bankrupt. A generation of kids grew up plastered to the TV set at each Moon launch.

Easterbook just doesn't get it. Earth observation is nice, but it can be done with existing technology - commercial space satellites, high atmosphere observation balloons and planes. It doesn't require the scientific and organizational might that NASA embodies. The moon base does have uses. Firstly, there is the study of human phisiology in space. Second, there is the construction of telescopes and sensors of various types to give us a much better understanding of space. Third, is the mining of HE3 (heavy helium) for propulsion purposes. Fourth, is a platform for other space operations. It is going to be expensive. No doubt.
I agree that the space shuttle is a problem. But I don't understand why he brings up the two disasters seen on TV. It is as though he thinks that the real disaster was the PR problems which resulted. If that is the case, he is only making it worse. What we need is a redesigned shuttle. The Shuttle is out of date. There are new technologies that could be harnessed to make it better. In addition, there is the very real problem that the shuttles wear out. They may be reusable, but that doesn't mean they are going to last forever.
I want to see more funding on long term programs, the far-out stuff like NERVA, anti-gravity, and the like. These are the kind of programs that NASA was chartered for.
Why were the wooden boats that sailed across the oceans funded?
We're living in the "bland" era of quarterly plans and short-term profits. And that era is rapidly coming to and end. If we don't start figuring out the technology, psychological and physiological implications for non-earth colonies then we won't be able to accomplish them when we need them. Which, at our current rate of resource consumption, won't be more than 20 years.
What do we want to be able to do in 50 years? A hundred? Not a "far out" question for younger generations who will, after advances in genetics (as in knowing how we damage ourselves) and bio-technology will likely be "middle-aged" then. We could choose to leave a good legacy...
Only if having a point of view is biased. Being human we all have our biases of course, and these naturally (mis)inform our viewpoints. But this doesn't license you to throw around the accusation of "bias" every time you see an opinion you don't like, because to be fair you'd have to tell the entire world including yourself to STFU.
No, the only behavior that merits this charge is the practice of bias.
Consider the following statement:
A hypothetical example of bias would be if the Earth monitoring missions had moved to a different agency, say, EPA, Mr. Easterbrook knew it, and chose not to mention it. Or if the programs had been phased out and replaced by more cost effective ones. In that case you can justify calling the article "biased".
This kind of bias is the sophisticated liar's lie; when you mislead by leaving out context, you can lie without actually saying anything untrue.

The budget cuts wouldn't be so easy if Joe Sixpack understood what NASA was doing. If NASA could come out and show more end products that produced a better "wow" factor Joe would back them more.
Most people don't see the value in collecting comet dust. But if you show them something that NASA R&D is doing for them today they might buy into it more.
Government budgeting is a popularity contest. Give the people something they can get behind and support, not technobabble they don't care to understand.
If NASA could show the direct effect the have on earthbound technology people would want more. Maybe we can get Al Gore to claim that NASA invented the Internet.

There's another particularly good use for a moon base that I can think of: experience.
As of yet, we have no actual experience building on any environment other than our terran terrains. Prognosticators tell us that building on other planets with less human-friendly environments may become desirable some day (such as Mars). The moon is a (relatively) close place to build in a (relatively) hostile environment -- moreso than Mars in many respects. Building a moon base and keeping it inhabited for a time -- especially by inhabitants doing run-of-the-mill human functions, many of which (if history has anything to say about man) seem to go something like this:
- ...
- ...
- do something stupid
- ...
- die.
would help us to run into the sorts of problems we might also be likely to have on other planetsAnd while they're at it, building telescopes, doing low-G experiments, and all those other fun things could be accomplished as well.
Mars, or even a base on the moon, most certainly test our limits. We'll be putting more stuff on the moon than we ever had, landing on places that we never could. AS far as Mars goes, what bigger test of a limit do you need than that? If anything robots do not test our limits at all, but manned flight does. If a robot screws up, so what, but if a manned flight screws up, boom. For that reason, to echo Jack Kennedy: "We choose to go not because it is easy, but because it is hard."
And PS, we have to beat the Chinese back to the Moon, and to Mars.

How 'bout the last three decades. The shuttle was a clunker from the day they decided to use its present design. The concept is great. But, to me, it's all about the execution. The shuttle is a result of pure politics and all its encumbrances with just enough tech to bring the astronauts back alive most of the time. For NASA to function properly, it will have to become a serious issue to the voters, and right now they're too distracted by American Idol...or is it The Great Race?
What?
So yes they have some whacked priorties-that in essence meens that US Citizens have whacked priorties for science and grants funding.
I challenge anyone of you backseat slashdot readers to do better.
Let us not forget some of the associated programs are why we have some of the things we have now: Internet, TCP/IP Satalight TV, or even space probes to whine about at all.
If you think you can do better they're not hard to find -I'm sure a few people in washington would be glad to hear from you untill then...
NASA websites are supposed to have a 'last modified' date -- that one didn't. If you check the link, it goes to planning documents from 2002.

From the link they cite as a source, trim off the url down to 'codez'
(I don't know what they've done to the PDF, but you can't copy/paste from it cleanly
I'd still recommend looking that the PDF, as it seems to the only place on the Internet that has the full breakdown of the goals into the sub-goals -- see the Appendix, starting on page 43 (counting by the PDF, not by the document's internal numbering)
Build it, and they will come^Hplain.
Why not have NASA focus again on engineering (i.e. putting people in space is primarily an engineering task) that pushes the edge of what is possible (e.g. manned lunar/Mars/asteroid rondesvous, etc) and leave the earth science to other countries that have fewer ties between their poiticians and their science programs (how about somewhere that actually signed Kyoto?).
science is a religion
Unmanned space probes are cool, no doubt, but manned space flight is where it is at. We have to learn how to live off planet. There is a whole universe that, absent any proof of intelligent life, is ours for the taking, and using NASA to create some orbital mirror of satellites with which we can watch ourselves flex is boring. I don't fund NASA so some scientist who can't get a job making a cool product can do a thesis, I do it so that I can be inspired, and yes, manned space flight is inspiring.
I like the Space Shuttle. Yes, we can rail on about how it didn't meet its goals, how it was overhyped, but stop for a moment and look at what it actually is and does? It's practically a space station in its own right, it is so big. It launches like a rocket, lands like a plane, can bring back stuff in a fairly roomy cargo bay and has a cool robot arm. It's turned the notion of in-space assembly from the stuff of science fiction into ho hum routine. Before the space shuttle, we didn't even know if we could build a human space habitat. Sure, we could launch one, but build one? And we've done it.
I wish that we could build a newer shuttle, and, I wish we could send it to the Moon. I understand that CEV is better built for that. But, when they launch that CEV, look around inside, and compare it to the shuttle. The new CEV will have less room than the old shuttle.
BIG IS BETTER

13 billion. You say that as though it's an astronomical sum. To you and I, who measure things in hundreds or maybe thousands of dollars, it is. To the federal government, whose budget is in the trillions, and who can run deficits with near impunity, it's less than pocket change.
13 billion is less than 0.7 of the total federal budget. It's practically nothing. And it's one of the few government agencies that can actually produce real, tangible, ROI in terms of technology developed, not to mention the advances in our understanding of the universe, which can't be measured in dollars and cents.
Contrast your precious 13 billion to what else the government blows money on -- 553 billion on military expenditures (not counting veteran's benefits which account for another 76 billion). We've dropped 250 billion in just a few years on this Iraq war. Nearly 80% of the national debt is military related, and the interest alone nears 353 billion dollars. Per year.
And you're saying NASA is overbudgeted?
Yes, they could do a lot more if they funneled money into R&D for mass production, modular probes, fast cheap and out of control. But 13 billion is not really a lot to play with for a program that is, by its very nature, expensive. With mass production, you could possibly lower the manufacture costs per probe, but what about the not-cheap task of actually launching them, designing new ones, administration overhead, on and on?
When you think about all the stuff we have today that is a direct result of the space race, 13 billion is not asking a lot, and is far from being the most bloated of government spending.

"We sent mission xyz to rondesvous with iron/nickel asteroid foo. We successfully used a solar oven to refine the material and produce x kg of steel alloy pqr."
I keep hearing about in-situ resouce utilization, but it's not going to happen if we just keep sending probes that take pictures and measurments and don't actually do anything. Science is important, but it is a lot easier to piggyback science on an engineering mission than it is to use science-only missions to pave the way for something useful. Science probes have their place, but how many probes do we need to tell us that there is water ice on the moon and Mars? If we did missions to take advantage of what we already know, it's not that big of a step to do the same thing in a different place (e.g. sending a mission to Titan after developing the technology on Mars and the moon would mostly require a bigger rocket and powerplant that doesn't rely on the sun).
science is a religion
The notion that we can actively affect earth's climate is ridiculous.
I say we get launch costs down and start building massive, massive projects in outer space. Inter-planetary cruisers, asteroid mining operations, giant orbiting greenhouses and what not. Start building city in the sky, make it possible for average joe to save a half mil and live in outer space. Then you can do all the earth observation you can handle.
When you set up a bureaucracy, expect it to act like one.
Self-preservation and growth are the goals, not accomplishing any 'mission' they may be charged with. That mission is useful rhetoric in gaining the real goals.
Bureaucracies are evolutionary systems, forms of life. They are as alien to individual humans as reptiles.
The Space Shuttle was a stupid idea from the beginning, and all of the problems were predicted in advance. In fact, few predictions were as bad as the reality has turned out to be.
The decision to build and operate the shuttle was NOT made for mission-related reasons.
If you want to have space explored, you must work to abolish NASA and repudiate all of the international treaties preventing corporations from making profits.
NASA has blocked, frustrated and foiled all attempts by other organizations to explore and exploit space.

The article's author seems to be arguing that NASA's main priorities should focus on areas of earth science. While I agree that earth science is important, I have to wonder how much NASA should even care about that stuff -- they are an aeronautics and space administration after all.
If I was head of another government department with a strong mandate for earth sciences (NOAA), I'd only want NASA's help to get some of my earth-pointing satalites up there and keep them flying -- and to stay out of the way beyond that.
So we have better ideas and better technology now. And we should move towards these better ideas and away from the old technology of the Space Shuttle. But keep in mind that we wouldn't have the better ideas and better technology today, were it not for the Space Shuttle Program.
"Crude and slow, clansman. Your attack was no better than that of a clumsy child."
The President names the head of NASA, the head of NASA sets the tone and agenda for the whole organization. Very rarely does the head of NASA not fall into line with the President's space policy (if he has one). Congress approves or disapproves the plan set forth under the direction of the NASA administrator. Thus the focus of the space program is directly traceable to the President's thoughts and goals in this area.
In addition to sending men to the moon/Mars being a good sound bite for the general public, manned missions tend to be heavily oriented towards a Florida/Texas locale with a subsequent influence on their economies. Considering the obvious interest our current President has in those states, it's one more reason (not the only one), this administration has focused on manned missions.
We need to find a better balance between manned and unmanned missions for NASA, I think the pendulum swings a bit too far in either direction sometimes, and now is one of them. They really do have a symbiotic relationship, and we have need of both. Apart from that, it's time to put the shuttle down and work on our next manned vehicle more seriously - there's no good reason to keep those things flying anymore, send one to the Smithsonian and call it a day.
The manned spaceprogram should be ended yesterday.
Complete waste of money.
Not one iota of useful has ever been done as a result of the manned space program. There is no reason to send people up to do pointless experiments on rats.
Furthermore, the shuttle is an outdated piece of junk. It is a crime to risk astonaut's life with it.
If you compare the good science that has been done with unmanned probes to the zilch that has been done on manned stations, you will see.
The manned program is politics and job creations- mostly in RED states like Alabama, Florida, and Texas.
Meanwhile they cut the real science- mostly in California which is BLUE.
NASA stands for National Aeronautics and Space Administration. NASA should only exist to "administer" funding to space and high altitude projects. Their mission should be similar to the FAA. The FAA does not build planes, does not do research into aerodynamics, nor do they fly planes. The FAA simply regulates air traffic and sets government policy on air traffic. NASA should do the same for space travel and space science. I am a space scientist and I shudder everytime I hear that NASA will be involved in a project. Not to mention that 13 billion dollars isnt that much when we are spending $200 a year on a selfish war!
Between the ISS and Shuttle ops, 40% of the budget goes to Lock-Mart and Boeing just to keep the ISS' lights on. Then 25% for technologies to support the Moon/Mars plan.
The remaining 35% ($5.3 bil) for space science can only go so far. Got existing missions to support/complete. Plus, this Administration ain't too hot on Earth science missions. The data returned tends to include a lot of climatology data they don't want to hear about, so it's cheaper to not collect the data in the first place, rather than twist researchers' arms after the fact.

We are in a race against time against catastrophe. This planet is a death trap that history (as attested in the fossil record) has shown time and again in mass extinctions, supervolcanoes, tsunamis, asteroid impacts, ect. The only way we are going to survive long term is to establish manned colonies and spread out in the universe, and we are behind schedule! Our manned space program is not a frivolous waste of time and rescources. What better science can be done by a rover that cannot be done better by a trained geologist on site? No rover or probe sent to the moon ever did a better job than the apollo astronauts, whose scientific accomplishments are often glossed over or ignored. Plans are afoot to construct a huge array of antennas on the lunar farside making the most awesome radio telescope ever concieved, but It WILL NOT get built without MANNED spaceflight! It is hyperbol to suggest that science funding is being permanently cut. The manned program needs more rescources NOW to re-establish capability to leave earth orbit (that we foolishly discarded 35 years ago after spending billions to develop it! At the same time They must finish the space station to meet international obligations and only the shuttle can do the job. This is only a temporary situation. The Shuttle WILL be retired in 2010, and after the CEV and associated boosters are developed their operating costs will be far lower than the shuttle. More of NASA's budget will then be available for a more robust science program. And as I have said, you will not be able to beat the science that can be done by astronauts, on site. But the most important thing is, in the wake of NASA's scientific explorations establishing infrastructure, private concerns for mining, construction, tourism, what have you, will follow, and the first space colonies will get started.
The shuttle was designed as a cold war tool to ferry spy sats to space and construct what was then an cold war platform in space (the space station), when the station was found to be really expensive, it was nexecssairy to re-define its role as international and get funding for other coutries.
The demensions of the cargo bay were intentionally designed to fit most spy and air force size sats (Nasa objected, said it was too big and would cost way too much), it therefore should be those two agencies that should pay most of the bills for running and paying for the R&D of building the shuttle (and it's replacements). That is only fair as basic sience programs like the Hubble telescope sufferd (amd still do), these programs had to wait 10 years of delays so that mill and spy sats could constanlly get launched. (programs like Seti even got pollitically made fun of and cancelled, but now we have signs that life could possibly exist in other parts of the solar system and most likely, in other star systems!)
If Nasa was funded properlly, we would have multiple Hubbles up there and not just 1 Hubble and dozens of equivallent cold war spy sats, we would have descent funding of Seti research (look at all the signs of life we are starting to find (mars, moons of other planets), the possibility of LOTS of planets around other solar systems like earth), and we waste Nasa's resources funding spy stuff and not exploring space/solar system.
Talk about two-faced, those gung-ho millitary amdinistrations that talk about tighening belts and the good old private sector can't get their facts and thinking straight about how their pet projects (mill air force and spy) should be funded from mill and spy budgets only, (ie: not steal from Nasa and then call Nasa names, cut it's funding etc.).
They blame Nasa while NOT privatizing the shuttle (privatinzing would relfec the real costs of the truck shuttle, then they should charge these real costs to air force and spy agencies, and following thier own tired mantras of "it's not the goverments role to do..etc., but it's Nasa's role to waste it's money funding a big space truck?? (stupid, stupid, makes no sense))
A hit, a very palpable hit!
Infuriate left and right
NASA = an academic welfare program to keep PHD's working. The wrap their work in beauracracy to explain why their work output is just as low as real academia. Its actually a step down from academia since they don't have grad students to do their work for them. Just another pork project from the Great Society.
$13 BILLION a year should be enough to launch a robotic probe to every planet and moon in the solar system, one to three probes launches per year.
Amen. People like this author bug me, so I'm going to rant for a bit.
Ok, so you missed out on the "Shuttle to Retire by 2010" headline by about 2 years. Also The fact that they are working under a mandate to develop a new crew vehicle and a new versatile heavy launch vehicle means nothing to the author. I'll ignore the international committment to the ISS involved here, because you did too, but this next quote is a doozy.
Yes, we all know that NASA hates taxpayers. "Hey all you people who pay our salaries...you suck! This isn't about learning new things or expanding human presence. It's about burning money...muahahaha."
You forgot about Clementine (NASA) and Smart-1 (ESA). Lemme make a comparison: Since the wrap up of the Apollo missions (the data of which is still being studied, to answer another paragraph from the article), there have been twice as many missions dedicated to studying the moon (not counting earth based observations/experiments or pre-apollo missions) as there have been to Mercury, Pluto, Uranus, and Neptune combined, ever. Plus, right now, during this supposedly sad time in exploration, missions to Pluto and Mercury are on their way, tripling the count!
Let's start with an argument illustrating how little you know about where science is now (trying to understand how the world works by exploring what happened 10^-33 seconds after the universe began...knowledge extremely useful in understanding and manipulating fundemental particles), and finish up with a show-stopping point about the project name. They then try to trump it's worth by comparing it to the delayed TPF, a mission which overlaps the Kepler Observatory in many aspects and looks for earth sized planets we don't expect to even be able to see directly for decades, and neither of these offer the same thing JWST does.
Wait a second, didn't you say we learned nothing from the moon trip except how to survive in space (a lesson which arguably has perhaps some value if we truly want to become spacefaring)? How is the moon a milestone in light of that statement? And are you saying all of these long-term microgravity experiments in genetics, fluid mechanics, combustion, biology, etc are almost worthless? What about engineering advances, like rockets designs still in use today?
Ok, I'm wasting too much time here, but further fallacious arguments the author makes or implies is that earth science can only happen from space (wow...just wow) and can only come from NASA projects, and that we're not spending enough learning how to deflect asteroids we don't even know are heading for our planet. That last one is easy for people to be concerned about, but the scale of all proposed methods compared to the probability of an impact makes for a really low benefit/cost ratio. Currently, NASA is focusing on cataloguing threats, rather than spending tons money on an umbrella that is full of holes for a place that goes thousands of years between rains.
Earth observation is nice, but it can be done with existing technology - commercial space satellites, high atmosphere observation balloons and planes. It doesn't require the scientific and organizational might that NASA embodies.
Well, it requires scientific and organizational might of some kind. Earth observation doesn't have the kind of commercial payoff that makes it an attractive venture for companies. Generally speaking, a government agency needs to take the lead in such an endeavor if it is to be done holistically. NASA is the de facto leader in this area for the US, and the point of the article is that they have botched the job.
The moon base does have uses. Firstly, there is the study of human phisiology in space.
Which can also be done much more cheaply in Earth orbit.
Second, there is the construction of telescopes and sensors of various types to give us a much better understanding of space.
Okay, I'll give you that one.
Third, is the mining of HE3 (heavy helium) for propulsion purposes.
He3? Heavy helium? For propulsion purposes?? I think you need to take Chemistry over again. He3 is not "heavy" helium -- it's one neutron lighter than He4. Or perhaps you meant heavy hydrogen, H3, aka tritium. Good luck making an engine that runs on that. Plasma physicists and engineers have been trying to make nuclear fusion work as a source of energy with deuterium-tritium interactions for decades now. Lots of progress, but still no reactor. It's a tough problem.
Fourth, is a platform for other space operations. It is going to be expensive. No doubt.
Expensive. And totally impractical. The only way it would work is if you found an abundant source of fuel and construction materials on the moon that are easy to harvest and to use. (Taking the fuel and material to the moon to use it there is a losing proposition.) And even then, you'd have to construct a significant infrastructure to do the harvesting, smelting, construction, etc. Starting from Earth really does make more sense.
Big organisations need the little guys as well as the big guys. Now you might want to tune up the organisation, but don't trash it all. There's a lot of little guys keeping the machinery running. Try telling the army to sack everybody apart from its combat troops and see where you are in six months...
As someone who is closely involved in the James Webb Space Telescope (JWST), I find the way that Easterbrook chooses to pitch it against Terrestrial Planet Finder (TPF) quite peculiar. He thinks that looking for the first galaxies that formed in the Universe with JWST is esoteric, which in some senses it may well be, but searching for planets around other stars with TPF is, for all practical purposes, equally so. Both goals are, nevertheless, very exciting and inspiring.
In fact, JWST is a general purpose observatory in much the same way Hubble is, and will enable a very broad base of astronomy, from cosmology at high redshift in the early Universe, all the way back to the formation of planetary systems in our own Galaxy, and to the study of objects in the Kuiper Belt of our own solar system. Again, practically speaking, these are all esoteric and yet you only have to look at the public's fascination with the enormous number of astonishing discoveries that Hubble and other astronomical telescopes have made to realise that such things play a vital role in our philosophical understanding of our part in this vast Universe.
With regards the idea that JWST is somehow NASA's spolied child, keep in mind that the US astronomy community identified it as its number one priority in the most recent Decadal Review of the National Academy of Sciences, along with the European and Canadian communities: NASA is following through on this outside recommendation. Of course, there are grave problems in the NASA space science budget and no-one likes to see missions cut or delayed, and yes, there have been cost overruns on JWST (albeit largely due to non-technical issues outside the JWST project's control), but it's simply wrong to believe that NASA has somehow made its difficult decisions in a vacuum.
Most astonishing though is Easterbrook's naive assertion about gravy train aerospace contractors building the JWST: just who, exactly, does he think is going to build TPF? A couple of University of Podunk astronomers and a dog? TPF is, if anything, even more technologically challenging than JWST and can only be built by many of the very same aerospace contractors: it's bonkers to think otherwise.
Finally, on naming the former Next Generation Space Telescope after James Webb, while, I remember very clearly the moment that was announced by NASA and yes, it was a bit of a shock. All the same, it's important to remember that Webb put in place much of NASA's space science program at the same time as running Apollo, so his credentials are respectable at the very least. In any case, get over it: let's get the JWST done and launched, and answer some of those fascinating esoteric questions.
First of all, 13B is ONE YEAR. Next year is paid for by ANOTHER 13B. Second of all, do the math. Let's say we need 10,000 people to manage the probe program (managers, engineers, secretaries, etc). Let's say it costs 100K per employee, just to be generous. That's only a billion dollars. That leaves another 12 billion.
You're very ignorant about where NASA spends its money. Almost all of it goes to multi-year projects, and most of it goes into hardware and fundamental science research. Nothing at NASA gets done in a single year -- period. The scale at which they operate and the technology that they work with cannot be invented, launched, and complete its mission in a single year's time. If you want to look at where NASA spends its money, go straight to their FY2007 budget request. Let's look at some highlights.
Their "Science" budget primarily covers their space probes for $5.3 bil. This is what you would fund exclusively in your proposal. Their "Exploration Systems" budget primarily covers technology development for manned and unmanned exploration of the surface of celestial bodies as well as propulsion and life-support research for $3.9 bil -- most of this goes to next-generation shuttle-replacement development. Running the Shuttle, the ISS, and miscellaneous space flight support goes under "Space Operations" for $6.2 bil. The rest is eaten up in "Cross Agency Support," "Aeronautics Research," and the "Inspector General" for $1.2 bil.
The Science budget goes the operation and development of space probes and telescopes. Probes in development range from $40 million to $443 million per year of development. The James Webb Space Telescope is the most expensive project at $443 mil. in 2007 and will cost a total of $4.5 billion dollars (over 1/4 of this years budget if paid for all at once). Just running the two Mars probes is costing $85 million in operational costs.
The cheapest mission I could find (per this year's budget) is the Magnetospheric Multiscale Mission, which will send up 4 identical satellites to take 3D images of the magnetospheric boundary. It costs $40 million this year, but it will run $700 million total including $140 million for the actual instrument. NASA projects are not cheap (though they're nothing compared to war and social programs).
Of course they cost $100 million -- NOW. That's because they're designed and custom-built every friggin' time. It's an incredibly wasteful and stupid method of construction. If you made three standardized types that were EXACTLY the same, except that you could plug standardized modules into it, you would save immense amounts of money. It's called "mass production", perhaps you've heard of it.
Sensor development is the majority of the cost of the probe. Power, propulsion, communication, etc. systems are already mostly standardized. You don't see mass manufacturing savings until you start getting above hundreds of units, generally speaking. Now, exactly what kind of missions do you imagine NASA using hundreds of identical space probes for that all carry the same kind of sensory equipment?
There aren't any. Every time we send up a single probe it's because that's the best information we can get with the technology currently available to study an object. If we sent up two probes, then we'd have the exact same quality of information in (for the sake of argument) half the time. However, time isn't our biggest cost here -- it's the launch costs, followed by the sensor costs (both R&D and production), and followed by the personnel costs for R&D and for operating the probe once it's active.
When we send future missions, we want to get better data, so we design new sensors. Space launch is so expensive that there's no point in sending up redundant space craft to accomplish what we could have done with one alone.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
They get to follow the whim of the current crop of politicians who decide on crazy wasteful goals. The cold war is over, there is no opponent to outrace to get somewhere in space using the most resources humanly possible. They need to refocus on practical stuff but what politician cares about that?
My gripe is NASA is becoming like the Soviet space program. It is becoming more secretive and reducing the science. OK so we had Apollo and its goal was not about science. However, we did not cut aeronautics and science during Apollo. We also figured it is better to have Apollo astronauts well trained in geology so they don't look stupid wandering the lunar surface.
Another gripe I have is everybody, and you know who you are, talk a lot about manned lunar and mars missions, or moon bases, etc. Well, as far as I'm planning such missions is a waste of time. A big rocket is needed, something the size of Saturn V (probably need something bigger), what we have now and what is planned is too small!!!!! In the 1960s, rocket scientists knew we had to have something big that can vault at least 100 tons (mass) to the moon (much of the mass is fuel). Russians did have a lunar spacecraft (the Soyuz) and were training cosmonauts for moon missions. But they did not put in enough effort to their N1 rocket, so they didn't go anyplace besides LEO.
I think NASA should be honest and say there really is not much science on ISS and Shuttle. But they should not cut back on other science and aeronautics. OK so money is tight but cutting back is a good way to piss off a bunch of people except for those in Texas and Florida. You gotta give everyone a piece of the action though the current administration doesn't seem to get it.
Countries that stop exploring become third world countries, Great Britain for example. Therefore as painful as it is, you gotta keep some human presence in space and at least have robots visit other planets.

In fact, a quick Google search throws up a long list of articles from TNR, The Atlantic, and Slate.com, etc., following a similar theme. This guy has been chipping away on this line for a long time now...
Lets not honor are agreements with other antions.
We are obligated to get certian thing for the space station up there, and right not the shuttle is all we got to do it.
Yes, NASA need a bigger budget.
Yes, the space shuttle needs replacing. Persoanlly, I think the 'space plane' way of getting up and down is the way to do it. That's another topic.
But we have commitments.

I think NASA has out lived its usefullness.
I disagree provided NASA's goals are framed in terms of basic exploratory science. The number of things we can learn about our own planet potentially has long-range economic benefits. Of course, we can't say it definitely has those benfits until we perform the science. Climate satellites have a huge potential to discover what effects the burning of fossil fuels has on global weather patterns, yet funding for these satellites is being cut.
This is completely nonsensical to me.
I'm suprised your comment was marked "insightful." Slashdot has been around for nearly 10 years; you'd think the moderators would know what a weak troll looks like.
I disagree.
The priorities are different, but not wrong.
There is a lot of He 3 in the moon, of which say a truckload can produce electricity for the whole of America for 1 full year.*
How do we get it? By mining.
How do we mine it? By having a moon base.
How do we transfer it here? By shuttles.
Simple.
And if NASA can bring back that much He3, then I guess funding for NASA is going to be much much higher for future missions.
*Considering that fusion is going to be a reality in 10 years, of course.

NASA is a pork machine, with a side of election year razzle-dazzle.
I'm as big a fan of space exploration as there is, and my dearest desire for humanity is for us to stop spending so much time trying to kill each other and instead pursue our destiny in space.
But NASA isn't going to do it for us, not the way it's structured now.
Still, it's better than most anything else we've got.
Screw your moonbase. I'm gonna make my own moonbase, with blackjack... and hookers...

The shuttle has been out of whack from day one. Fairly common knowledge also.
Design was driven by funding instead of what was needed.
You claim to be a space scientist, but you seem rather ignorant of how and why NASA was originally formed. Your post sounds as though you believe that NASA originally consisted of a bunch of bureaucrats whose sole purpose was to adminster grants awarded to corporations and educational institutions, and to set government policy on activities in space. This has always been a part of NASA's mission, but it is not the sole reason for NASA's existence. When NASA was formed in 1958, it maintained 3 research laboratories - it now has 10 such laboratories. Scientific research and the development of spacecraft and spacecraft instruments have always been a part of the NASA organization. Some work was contracted out in the past, as it is today, but NASA has always employed its own scientists and engineers.
...inventing a warp drive, flying it over just above the earth to wait for the Vulcans to pass by and have a First Contact with them, was the first priority.
:)
No?
And the impossible is: 1) Sending a 1 ton probe to Alpha Centauri (that would get there within 50 years:) (requires nuclear propulsion)
2) Sending a people to Mars (requires cheper alternatie to rockets - Linear accelerator/Space fountain/etc)
3) Building a space elevator (requires novel materials - mass produced infinite carbon nanotubes)
Im tired of rockets. Things are going nowhere with rockets, that they havent been before.
They sure are out of whack. It has been clear the shuttle has been a clunker since the 1970's. That 65 feet of man-rated cargo bay has been a disaster all along. I worked for NASA in the 1970's and it has always been a problem. It has cost too much, it has killed two crews so far, and it costs $500M + per launch to do nothing.
We get at least 10 times the bang per dollar with well defined robotic missions as with manned missions that have been useless tourism. Those are NASA's figures. I think the economic advantage to robots is more, having been there when this shuttle mess was conceived.
If you want manned missions, define a coherent mission for them. Going and being a tourist is not the answer. We have to define missions that involve people going into space to *stay*. They are not going to be visitors; they are going to be colonists. Otherwise stay on the ground and and use robots.
The "dark" side of the moon is a terrible place for an optical telescope (where you can probably safely read optical as extending from IR to X-ray.)
It's not dark all the time-- it's just that the moon is tidally locked to the earth so we never see the backside, but it sees plenty of sun, which gives it huge temperature swings, which isn't good for precision optical alignment.
There's also stuff like meteor impacts to deal with-- they cause vibrations and kick up dust.
And then there's the gravity well that you have to drop all the sensitive equipment down without breaking it. It's not like mars, where there's at least a little atmosphere for braking. On the moon you have to do all the braking yourself. It adds both mass and complexity (risk) to a space mission.
Floating out in space (earth trailing like Spitzer, or L2 like WMAP or the planned JWST) is pretty benign by comparison.
There might be ok arguments for an array of radio telescopes, but they're probably least likely to be built there due to the large size/mass of stuff that you have to transport.
The best NASA can manage is four flights a year, if they are lucky with tiles and other refurbishing. If they had no shuttle, they could lop off 5-10 billion dollars a year from their budget. Whether you bill that money to one flight, all flights, or the first flight, it's still way too damned much money for so little functionality. The most expensive expendable rockets are, I think, around $200M.
And NASA is now talking of mothballing the space station as soon as it is complete. This all belongs in Alice in Wonderland. They will spend $25-50B building something they intend to stop using as soon as it is built. They could send 100 probes for the same amount of money.
Someone ought to be shot.
Infuriate left and right
This makes it a shame that you started with NASA does environmental and climate research to please a voting constituent [sic] that would otherwise be opposed to space research. which is basically horseshit.
Dude, space scientists have been committed to climate research from before there was a NASA. Do ya know why?
Evidently not.
Because agribusiness, oil companies, large contractors, port managers, the military, and lots of others count on accurate weather data.
Remember the Normandy invasion? Before your time. A couple of guys going up a beach while some other guys tried to kill them. The whole thing was scheduled around the weather reports.
Howsabout farms. Heard of those? Bad predictions of climate change over, say, ten to twenty years, means first of all deeply fucked yields, low to zero profit, and, sometimes, as a couple of people in Louisiana, Alabama, and, oh, did I mention six or seven midwestern states have been learning, flooding bad enough to destroy the entire infrastructure. And then there's what climate change is doing to actual grownup, non-hippie concerns like real estate values, the accelerating disintegration of the permafrost-supported highways and oil pipelines and, oh, pretty much everything else north of, say, Alberta.
Now, I could go on about such non-hippie concerns as the possible incipient collapse of several major crops, starting with bananas, or the scrambling going on in the lumber industry or the thousands of deaths a year from mudslides in places like the Philippines and Central America or the very real and immediate problems port facilities around the world are facing from increased storms and rising sea levels or the increases in skin cancers or the military importance of better air and water turbulence data but it would probably just confuse you.
You just go on along and buy yourself some beach real estate in, say, Tuvalu, and when you're drowning during an "anomalous" storm, drop me a line and we can discuss this again.

Data is the lever, rigor the fulcrum, brains the force that drives it all.
Depends on how you define "doomsday scenario", there, cobber.
Some Native Americans were predicting the destruction of their civilizations back in the mid-1700s but nobody much listened. Same thing re the decimating of the buffalo, passenger pigeon, dodo, and so on.
Greek politicians and scholars were predicting their own downfall and the conquest by Rome *way* before it happened. IIRC, some pretty insightful predictions were made about the time Pyrrus was creating a new word for useless battle triumph.
Michael Brown tried to warn Dubya before Katrina but Shrub just yawned.
When Japan attacked Pearl Harbor one of their own admirals made a famous comment about "waking the sleeping tiger" that was none too happy and basically spot on.
And before that a U.S. military analyst had predicted Japanese imperialist island-hopping decades before it happened.
The sinking of a ship like the Titanic was laid out in great detail by a period writer.
Dozens (at least) of known examples exist of predictions of aircraft hitting the World Trade Center.
Plenty of Celts and, later Highlanders, predicted the triumph of the Romans and later, English.
And on and on and on.

NASA is caught in a trap. It has the ISS, which has to be the biggest white elephant of all time. It was going to be a dubiously useful space lab at one point, but since it has been down-scaled it has no point at all. It can only house a few crew now who must spend almost all their time on maintenance. The ISS has cost something like $50 billion. And for what? Just ask yourself - what does it DO for $50 billion. Not much.
Then there is the other piece of 'white' hardware, the Shuttle: why are we still bothering with it given.
1) It's enormous per-launch expense (~$1bn).
2) It's now dubious safety.
Well, the reason is the I in ISS. The US is committed to launching the components of the ISS built by international partners. This commitment is bound by international treaties. So NASA can't cancel it. Only the government could ever do that. However, both the Shuttle AND the ISS should be cancelled now rather than throwing more good money after bad.
Normally I wouldn't care about money being wasted on such things. I am not a US citizen, so I don't really have any right commenting on what you do with your own money. But the problem is that it is now affecting science missions in a BIG way, and I do care about that. NASA has worked out that they basically have this situation:
1) ISS + Shuttle.
2) Moon and Mars as human destinations, need new hardware (CEV etc).
3) Science missions (robotic probes, telescopes, etc).
Choose two.
They HAVE to choose 1+2 because they are bound to persue these by the US government - 1 because of international treaties and 2) because the President said so.
So it's up to American Citizens to let their representitives know that the real priorities should be (in my humble opinion):
3) and a new one: get the cheapest way to earth orbit - fund EXTERNAL research into space elevators, SSTO, TSTO, disposable launchers (SpaceX stuff) projects etc. Don't stop 'til you can launch people to LEO for $1million.
The only problem with this is that it would leave the US without access to orbit for longer which may be politically unacceptable - but it's no different from the current situation anyway.
Just my thoughts.
PS. I am referring to it as 'white' hardware purely because NASA human flight stuff always seems to be white. Oh yeah, and why did the first shuttle launch have a white fuel tank and later ones have an orange one?
I'd be satisfied if we could send a ten KILO probe to Alpha Centauri if it could take pictures and come back within, oh, a hundred and fifty years.
I'd guess that if somebody with their sh*t together and the right funding and staff (let's say the almost accepted applicants from Blue Origin) could get a one ton ship on the way in fifteen years. Start with a goal of sending multiple round-trip explorer robots to the moon within three years, the asteroid belt within five years, to the Kuiper belt within ten years, robot landers to the asteroids within eleven years, and then launching an interstellar probe by year fifteen.
Maybe I'm overoptimistic, but if so only by about ten years for the whole series if we assume redesigns based on performance of previous probes. Though this timeline assumes no NASA control at all, purely private organizations under private control.
Fifteen to twenty-five years to the launching of the first interstellar explorer. Think about it.

they decided killing people or research into killing people more efficiently was much more profitable...
I hate to tell you this, AC, but the vast majority of all technological advancements that you have around you today in some way was spurred along by teh concept of using the technology to kill people more efficiently or helping those who try to kill people more efficiently.
It reminds me of the scene in the film "Manhatten Project" when the military man asked Lithgow if he thought that the lab was there for his intellectual stimulation because the reality was that it was there to help kill more people more efficeintly.
If you have a hard time with that concept I'm afraid you're SOL because that's the truth behind most of your "neat" gadgets today.

What makes the opinions of a physicist regardign an engineering endeavor so wonderful?
It would be like a ENT commenting on the workings of a Physical Therapist
Scientist=!Engineer.
(that holds for orbital launch, the g there is to get the dimensionality right)
So, lets take a 1 tons probe (nuclear reactor for power, lasers for comunication, instruments), 60 000 sec specific impulse for the rocket engines that would fling it towards Alpha Centauri (doable with Orion nuclear engine - the nuclear propulsion system that we have reserached mostly at the moment - in the '60s) and total launch weight of 200 tons (equal to the weight of the space station). end speed is then 11 000 000 m/s.
Proxima Centauri is 4.3 light years away = 4e16 meters
So, the probe would get there in about 120 years :)
Perfectly doable with all the knowledge, technology and resources we have (and have put to good use for other applications) today
I agree, as you can see from my comment further down in the post. My point was that I'll take anything I can get at this stage of the game. Even a probe, any probe, scheduled to take five hundred years there and back would make me very happy as it would force us to address the technical issues involved and give kids something to aspire to as they work out what they want to do with their lives.
As for your mission duration numbers, I'd say that with ten years to design and build we should certainly be able to cut that down to fifty if it's done as a government mega-project. Given the idiocies we spend money on now, I might even agree that NASA should put exploratory money into next year's budget for such a probe.
But my point was that we don't have to wait for NASA at all. A far smaller organization with far less pork and distractions, getting experience by building a succession of probes going farther and farther within the solar system, using that learning curve as they go, could start today, be launching useful probes in five years, and interstellar not too long after that.
And I can guarantee you that Rutan, and/or Bezos and/or Branson and/or any of the several dozen other contenders think the very same thing.
Hell, if I had the resources that would certainly be on my radar.
