Why Explore Space? A 1970 Letter to a Nun in Africa

Ernst Stuhlinger wrote this letter on May 6, 1970, to Sister Mary Jucunda, a nun who worked among the starving children of Kabwe, Zambia, in Africa, who questioned the value of space exploration. At the time Dr. Stuhlinger was Associate Director for Science at the Marshall Space Flight Center, in Huntsville, Alabama. Touched by Sister Mary’s concern and sincerity, his beliefs about the value of space exploration were expressed in his reply to Sister Mary. It remains, more than four decades later, an eloquent statement of the value of the space exploration endeavor. Born in Germany in 1913, Dr. Stuhlinger received a Ph.D. in physics from the University of Tuebingen in 1936. He was a member of the German rocket development team at Peenemünde, and came to the United States in 1946 to work for the U.S. Army at Fort Bliss, Texas. He moved to Huntsville in 1950 and continued working for the Army at Redstone Arsenal until the Marshall Space Flight Center was formed in 1960. Dr. Stuhlinger received numerous awards and widespread recognition for his research in propulsion. He received the Exceptional Civilian Service Award for his part in launching of Explorer 1, America’s first Earth satellite.
Dear Sister Mary Jucunda:
Your letter was one of many which are reaching me every day, but it has touched me more deeply than all the others because it came so much from the depths of a searching mind and a compassionate heart. I will try to answer your question as best as I possibly can.
First, however, I would like to express my great admiration for you, and for all your many brave sisters, because you are dedicating your lives to the noblest cause of man: help for his fellowmen who are in need.
You asked in your letter how I could suggest the expenditures of billions of dollars for a voyage to Mars, at a time when many children on this Earth are starving to death. I know that you do not expect an answer such as “Oh, I did not know that there are children dying from hunger, but from now on I will desist from any kind of space research until mankind has solved that problem!” In fact, I have known of famined children long before I knew that a voyage to the planet Mars is technically feasible. However, I believe, like many of my friends, that travelling to the Moon and eventually to Mars and to other planets is a venture which we should undertake now, and I even believe that this project, in the long run, will contribute more to the solution of these grave problems we are facing here on Earth than many other potential projects of help which are debated and discussed year after year, and which are so extremely slow in yielding tangible results.
Before trying to describe in more detail how our space program is contributing to the solution of our Earthly problems, I would like to relate briefly a supposedly true story, which may help support the argument. About 400 years ago, there lived a count in a small town in Germany. He was one of the benign counts, and he gave a large part of his income to the poor in his town. This was much appreciated, because poverty was abundant during medieval times, and there were epidemics of the plague which ravaged the country frequently. One day, the count met a strange man. He had a workbench and little laboratory in his house, and he labored hard during the daytime so that he could afford a few hours every evening to work in his laboratory. He ground small lenses from pieces of glass; he mounted the lenses in tubes, and he used these gadgets to look at very small objects.  The count was particularly fascinated by the tiny creatures that could be observed with the strong magnification, and which he had never seen before.  He invited the man to move with his laboratory to the castle, to become a member of the count’s household, and to devote henceforth all his time to the development and perfection of his optical gadgets as a special employee of the count.
The townspeople, however, became angry when they realized that the count was wasting his money, as they thought, on a stunt without purpose. “We are suffering from this plague,” they said, “while he is paying that man for a useless hobby!” But the count remained firm. “I give you as much as I can afford,” he said, “but I will also support this man and his work, because I know that someday something will come out of it!”
Indeed, something very good came out of this work, and also out of similar work done by others at other places: the microscope. It is well known that the microscope has contributed more than any other invention to the progress of medicine, and that the elimination of the plague and many other contagious diseases from most parts of the world is largely a result of studies which the microscope made possible.
The count, by retaining some of his spending money for research and discovery, contributed far more to the relief of human suffering than he could have contributed by giving all he could possibly spare to his plague-ridden community.
The situation which we are facing today is similar in many respects. The President of the United States is spending about 200 billion dollars in his yearly budget [more than $2 trillion in 2012]. This money goes to health, education, welfare, urban renewal, highways, transportation, foreign aid, defense, conservation, science, agriculture and many installations inside and outside the country. About 1.6 percent of this national budget was allocated to space exploration this year [less than .5 of one percent in 2012]. The space program includes Project Apollo, and many other smaller projects in space physics, space astronomy, space biology, planetary projects, Earth resources projects, and space engineering. To make this expenditure for the space program possible, the average American taxpayer with 10,000 dollars income per year is paying about 30 tax dollars for space. The rest of his income, 9,970 dollars, remains for his subsistence, his recreation, his savings, his other taxes, and all his other expenditures.
You will probably ask now: “Why don’t you take 5 or 3 or 1 dollar out of the 30 space dollars which the average American taxpayer is paying, and send these dollars to the hungry children?” To answer this question, I have to explain briefly how the economy of this country works. The situation is very similar in other countries. The government consists of a number of departments (Interior, Justice, Health, Education and Welfare, Transportation, Defense, and others) and the bureaus (National Science Foundation, National Aeronautics and Space Administration, and others). All of them prepare their yearly budgets according to their assigned missions, and each of them must defend its budget against extremely severe screening by congressional committees, and against heavy pressure for economy from the Bureau of the Budget and the President. When the funds are finally appropriated by Congress, they can be spent only for the line items specified and approved in the budget.
The budget of the National Aeronautics and Space Administration, naturally, can contain only items directly related to aeronautics and space. If this budget were not approved by Congress, the funds proposed for it would not be available for something else; they would simply not be levied from the taxpayer, unless one of the other budgets had obtained approval for a specific increase which would then absorb the funds not spent for space. You realize from this brief discourse that support for hungry children, or rather a support in addition to what the United States is already contributing to this very worthy cause in the form of foreign aid, can be obtained only if the appropriate department submits a budget line item for this purpose, and if this line item is then approved by Congress.
You may ask now whether I personally would be in favor of such a move by our government. My answer is an emphatic yes. Indeed, I would not mind at all if my annual taxes were increased by a number of dollars for the purpose of feeding hungry children, wherever they may live.
I know that all of my friends feel the same way. However, we could not bring such a program to life merely by desisting from making plans for voyages to Mars. On the contrary, I even believe that by working for the space program I can make some contribution to the relief and eventual solution of such grave problems as poverty and hunger on Earth. Basic to the hunger problem are two functions: the production of food and the distribution of food. Food production by agriculture, cattle ranching, ocean fishing and other large-scale operations is efficient in some parts of the world, but drastically deficient in many others. For example, large areas of land could be utilized far better if efficient methods of watershed control, fertilizer use, weather forecasting, fertility assessment, plantation programming, field selection, planting habits, timing of cultivation, crop survey and harvest planning were applied.
The best tool for the improvement of all these functions, undoubtedly, is the artificial Earth satellite. Circling the globe at a high altitude, it can screen wide areas of land within a short time; it can observe and measure a large variety of factors indicating the status and condition of crops, soil, droughts, rainfall, snow cover, etc., and it can radio this information to ground stations for appropriate use. It has been estimated that even a modest system of Earth satellites equipped with Earth resources, sensors, working within a program for worldwide agricultural improvements, will increase the yearly crops by an equivalent of many billions of dollars.
The distribution of the food to the needy is a completely different problem. The question is not so much one of shipping volume, it is one of international cooperation. The ruler of a small nation may feel very uneasy about the prospect of having large quantities of food shipped into his country by a large nation, simply because he fears that along with the food there may also be an import of influence and foreign power. Efficient relief from hunger, I am afraid, will not come before the boundaries between nations have become less divisive than they are today. I do not believe that space flight will accomplish this miracle over night. However, the space program is certainly among the most promising and powerful agents working in this direction.
Let me only remind you of the recent near-tragedy of Apollo 13. When the time of the crucial reentry of the astronauts approached, the Soviet Union discontinued all Russian radio transmissions in the frequency bands used by the Apollo Project in order to avoid any possible interference, and Russian ships stationed themselves in the Pacific and the Atlantic Oceans in case an emergency rescue would become necessary. Had the astronaut capsule touched down near a Russian ship, the Russians would undoubtedly have expended as much care and effort in their rescue as if Russian cosmonauts had returned from a space trip. If Russian space travelers should ever be in a similar emergency situation, Americans would do the same without any doubt.
Higher food production through survey and assessment from orbit, and better food distribution through improved international relations, are only two examples of how profoundly the space program will impact life on Earth. I would like to quote two other examples: stimulation of technological development, and generation of scientific knowledge.
The requirements for high precision and for extreme reliability which must be imposed upon the components of a moon-travelling spacecraft are entirely unprecedented in the history of engineering. The development of systems which meet these severe requirements has provided us a unique opportunity to find new material and methods, to invent better technical systems, to manufacturing procedures, to lengthen the lifetimes of instruments, and even to discover new laws of nature.
All this newly acquired technical knowledge is also available for application to Earth-bound technologies. Every year, about a thousand technical innovations generated in the space program find their ways into our Earthly technology where they lead to better kitchen appliances and farm equipment, better sewing machines and radios, better ships and airplanes, better weather forecasting and storm warning, better communications, better medical instruments, better utensils and tools for everyday life. Presumably, you will ask now why we must develop first a life support system for our moon-travelling astronauts, before we can build a remote-reading sensor system for heart patients. The answer is simple: significant progress in the solutions of technical problems is frequently made not by a direct approach, but by first setting a goal of high challenge which offers a strong motivation for innovative work, which fires the imagination and spurs men to expend their best efforts, and which acts as a catalyst by including chains of other reactions.
Spaceflight without any doubt is playing exactly this role. The voyage to Mars will certainly not be a direct source of food for the hungry. However, it will lead to so many new technologies and capabilities that the spin-offs from this project alone will be worth many times the cost of its implementation.
Besides the need for new technologies, there is a continuing great need for new basic knowledge in the sciences if we wish to improve the conditions of human life on Earth. We need more knowledge in physics and chemistry, in biology and physiology, and very particularly in medicine to cope with all these problems which threaten man’s life: hunger, disease, contamination of food and water, pollution of the environment.
We need more young men and women who choose science as a career and we need better support for those scientists who have the talent and the determination to engage in fruitful research work. Challenging research objectives must be available, and sufficient support for research projects must be provided. Again, the space program with its wonderful opportunities to engage in truly magnificent research studies of moons and planets, of physics and astronomy, of biology and medicine is an almost ideal catalyst which induces the reaction between the motivation for scientific work, opportunities to observe exciting phenomena of nature, and material support needed to carry out the research effort.
Among all the activities which are directed, controlled, and funded by the American government, the space program is certainly the most visible and probably the most debated activity, although it consumes only 1.6 percent of the total national budget, and 3 per mille (less than one-third of 1 percent) of the gross national product. As a stimulant and catalyst for the development of new technologies, and for research in the basic sciences, it is unparalleled by any other activity. In this respect, we may even say that the space program is taking over a function which for three or four thousand years has been the sad prerogative of wars.
How much human suffering can be avoided if nations, instead of competing with their bomb-dropping fleets of airplanes and rockets, compete with their moon-travelling space ships! This competition is full of promise for brilliant victories, but it leaves no room for the bitter fate of the vanquished, which breeds nothing but revenge and new wars.
Although our space program seems to lead us away from our Earth and out toward the moon, the sun, the planets, and the stars, I believe that none of these celestial objects will find as much attention and study by space scientists as our Earth. It will become a better Earth, not only because of all the new technological and scientific knowledge which we will apply to the betterment of life, but also because we are developing a far deeper appreciation of our Earth, of life, and of man.
The photograph which I enclose with this letter shows a view of our Earth as seen from Apollo 8 when it orbited the moon at Christmas, 1968. Of all the many wonderful results of the space program so far, this picture may be the most important one. It opened our eyes to the fact that our Earth is a beautiful and most precious island in an unlimited void, and that there is no other place for us to live but the thin surface layer of our planet, bordered by the bleak nothingness of space. Never before did so many people recognize how limited our Earth really is, and how perilous it would be to tamper with its ecological balance. Ever since this picture was first published, voices have become louder and louder warning of the grave problems that confront man in our times: pollution, hunger, poverty, urban living, food production, water control, overpopulation. It is certainly not by accident that we begin to see the tremendous tasks waiting for us at a time when the young space age has provided us the first good look at our own planet.
Very fortunately though, the space age not only holds out a mirror in which we can see ourselves, it also provides us with the technologies, the challenge, the motivation, and even with the optimism to attack these tasks with confidence. What we learn in our space program, I believe, is fully supporting what Albert Schweitzer had in mind when he said: “I am looking at the future with concern, but with good hope.”
My very best wishes will always be with you, and with your children.
Very sincerely yours,
Ernst Stuhlinger
Associate Director for Science

Everybody! on Mars…and a Global Golden Age

“Whitey on the Moon” was a thought-provoking poem sung by Gil Scott-Heron during the 1970s. It is important to keep in mind, first, NASA is incredibly diverse — and hopefully headed to more profitable destinations than the moon (asteroids for commercial development and Mars for cultural change, scientific advancement, and enlightenment). NASA’s current administrator, Charles Bolden, is a former Naval Academy grad, 34 year Marine Corps veteran, astronaut — and, a black man. We still have a long way to go but chances are the first person setting foot on Mars may be neither white nor male. Nor American.

As for resource distribution: NASA’s budget is 18 billion a year, which is less than one half of one percent of the Federal budget. 18 billion is still a vast sum — even in comparison to 1.2 trillion squandered in Iraq. Everyone involved in the space program is acutely aware of competing worthy social programs; questioning proper allocation of funds will always be appropriate.  (Including the lowering of taxes and encouragement of private enterprise….)

Every single cent passing through the government could be immediately allocated to pressing life-saving needs. Stoplights, street signs, ambulances, body armor, medications, etc., are immediately useful — equally important long-term investments include education, weather satellites, medical research, national parks, air traffic control, and so on. In this triage ‘balancing’ of immediate and long-term humane compassionate interests, we decide to allocate funds for commercialization of near-Earth resources, increased scientific understanding of our universe, and the establishment of a self-sustaining, permanent Martian civilization.

50 billion to send the first settlers to Mars will do more to propagate Freedom and Tolerance in the Middle East than trillions squandered in Iraq. In the future when humans on Earth reflect upon the reality of persons living on Mars — who are enjoying their lives, progressing and thriving…while not giving a damn about returning Messiahs or Mahdis a planet away in Jerusalem or Medina — there could then be a cultural renaissance here on Earth. This could result in redirection of resources on Earth — from culture wars to real problems such as: poverty, illiteracy, conservation, etc.

The interesting thing is: this Global Golden Age could be the result of cultural change, not direct scientific advancement. Once humans are living on Mars, they will scientifically explore it to our benefit here on Earth and their immediate interest on Mars. In our current culture wars we have tried everything else…if it only takes a few boots on Mars, why not use them to jumpstart enlightenment here on Earth?

Lyrics to “Whitey on the Moon” by Gil Scott-Heron:

A rat done bit my sister Nell
with whitey on the moon
her face and arms began to swell
and whitey is on the moon
I can’t pay no doctor bills
but whitey is on the moon
ten years from now I’ll be payin’ still
with whitey on the moon ya know?
the man just upped my rent last night
cause whitey is on the moon
no hot water, no toilets, no lights
but whitey is on the moon
I wonder why he’s uppin’ me? cause whitey is on the moon
well I was givin’ him 50 dollars a week
and now whitey is on the moon

Taxes takin’ my check
the junkies make me a nervous wreck
the price of food is goin’ up
and as if all that crap wasn’t enough a rat done bit my sister Nell
with whitey on the moon
her face and arms began to swell
with whitey on the moon
with all that money I made last year
put whitey on the moon
how come I aint got no money here?
Hmmm whitey on the moon
ya know I just about had my fill
of whitey on the moon
I think I’ll send these bills air mail special to
whitey on the moon

Help can’t even help now
and whitey is on the moon
aid for my brothers and sisters
how whitey is on the moon
guess we’ll just sit by dyin’
with whitey on the moon
dogs have better luck at their tails tryin’
whitey is on the moon
fed up us people are
and whitey is on the moon
the slogan poverty or bust
later to whitey on the moon

Bob Zubrin’s Closing Statements at the 13th Annual International Mars Society Convention (Twitter: #MSC2010 )


Mars Society Executive Director Lucinda Land: And most of all I want to thank you for coming here, ’cause I know it’s a costly thing to travel and to — I appreciate your time and your effort — and the expense of coming to our convention — and I really appreciate that you’re here and showing your support.  And I look forward to seeing you next year, um, at our convention in Dallas.  For the final statements I’d like to turn it over to Dr. Robert Zubrin. Please welcome him, thank you.

Mars Society President Bob Zubrin: So, ah, I’d just like to reiterate, and ah, this is not pro forma, my thanks to the people who organized this conference — who made it possible, the Ohio chapter especially — but also, of course, Pat Czarnik, Lucinda, and others that aren’t even here — Sue Martin and Freya Jackson…this stuff, it doesn’t happen by itself, and um, this was really a bang up job, and, I’m really grateful to the people who put up the effort. No one got a dime to get things done, and, a lot was done. So. I might want to mention on the subject of money we did raise about 11,000 dollars last night at the banquet, and uh, that’s a good thing — and that is also, obviously needed, but a demonstration of the kind of commitment that is needed more broadly and makes everything happen.

Now, um, lots been said at the convention here, and, there isn’t really that much to add, ah, that hasn’t been said, nevertheless it’s useful to underline the subject: we’re in a battle, um, it’s a big battle, ah, it’s an important one. We have an — possibilities for things to move in very different directions at this point.  The situation was thrown into flux, ah, when Bush and Griffin left office — there was a certain program which was in place that — ffhhwwwwwt —  was ripped up…and that program was not perfect from our point of view. Not — hardly. Anyone who’s been to these conventions knows that I’ve been quite critical of many aspects of it, but at least it was something– but at least it would have given us a heavy lift booster, a capsule, an interplanetary throw stage — about half the hardware set we would have needed to go to Mars. At least it was a way to have some form of progress in our space program.

The, um — what happened in February — it was a put up job! — John Holdren, Barack Obama’s Science Advisor — a long time enemy of human spaceflight, a long time enemy frankly of industrial civilization and technical progress — you can verify that, if you look up the books which he has co-authored with a man named Paul Ehrlich who’s an ardent advocate of the whole zero-growth thesis, that human growth need to be stopped, human growth, population growth, technical growth — this has all got to stop. And in fact he calls the United States an “over-developed country” that needs to be de-industrialized. If you read these books — they’re amazing — whenever they use the word “progress” they put it in quotes. And…in other words they can’t even say the word progress with a straight face. “Our more advanced civilization…” blah, blah, blah.  Okay? Out of their deep concern for the people in Africa they want to prevent them from having to live in the conditions that we live in today…ah — and would prefer, actually, that it go the other way.

But the space program is — of course — the…well, the space program is two things, isn’t it. NASA…the government program — which after all is the main space program which actually exists — as opposed to the private one, which we’re all hoping will emerge — but the one which has existed up to now is the NASA program. And it has two sides to it, doesn’t it. There is — as its opponents say — this huge wasteful bureaucracy and it does wasteful things and it is bureaucratic and you name it — on the other hand, there is NASA as the symbol, of the pioneer spirit, there is NASA as the symbol of the “can do” American spirit: WE CAN DO ANYTHING.

And…ah…of self-reliance, ingenuity — the ability of progress to make things possible that were never possible before. Okay…and…ah, after all…when we went to the moon what was it fundamentally saying? “FREE PEOPLE CAN DO ANYTHING. THERE IS NO CHALLENGE THAT’S BEYOND US.” And there are no limits to human aspirations, and human aspirations do not need to be constrained in order to, ah, fit within certain limits, that some people might want to impose upon us. There’s those two aspects. So what?

So, NASA — not as bold as it was in the 60s by any means — but still, under the previous plan, we’re returning to the moon — “Ok, we’re returning to the moon. We’re going back to where we were the last time we made that statement” — and presumably we would go on from there. And they killed that program. And they killed it: will malice of forethought. Look, there has been a certain number of people in this country, who have said, “We have other needs, the space program is absorbing all this enormous amount of money” — even though frankly it’s not all that much, it’s half of a percent of the Federal budget at this point — but still, “19, 20 billion dollars is not pocket change, we would like to spend it on something else.” I can respect that point of view. There are other needs to be met and one could debate what the money should be spent on.

But — they didn’t do that. They didn’t cut NASA’s budget in order to spend the money on social programs. Or housing projects or highway repairs or body armor for the troops — or tax reductions. They didn’t cut the NASA budget at all — they just aborted the program. Okay. And instead of having NASA spend its money to restate — what it said before, to restate that America still has the right stuff — that we still adhere to the pioneer spirit, that we’re still willing to take great risks to do great things, and prove that the impossible is possible…okay…they ah, said, “Fine. We’ll give you the money, because we know all you really care about are your jobs — so we’ll give you three billion a year to refurbish the Shuttle launch pads after the Shuttle stops flying.” I’m not making this up.

Originally they wanted to kill the Orion altogether — but finally when there was push back — they said, “Well, look, we understand, you don’t want to be able to send Americans to orbit…all you care about are your jobs, so we’ll give you your jobs, you can have your Orion money, we don’t care, just so long as it cannot take astronauts to orbit — so we’ll give you an Orion that goes down and not up. I mean this is: incredible. I mean I’ve never seen anything like this. Carter — wrecked the space program — but at least he spent money and spent it on something else. We can argue about whether that was a good idea — I don’t think it was — but at least it was…ah, ah, on the level, in the sense of saying, “I want to take this money and spend it on something that I think is more valuable.”  Instead, “Well, okay…you don’t like the Shuttle program shutting down, so why don’t we keep the Shuttle program going except we won’t fly any Shuttles, or, maybe we’ll fly one.” You know…and, so, this is incredible. It is…degrading. Okay, to NASA. It is degrading to everyone in NASA to be told this: “You’re only objecting to the shut down of the program because it’s your paycheck — ‘well, we’ll give you your paycheck, how’s that? We just don’t want you to accomplish what you claim you’re trying to accomplish.'”

Think how degrading that is. And yet they cynically do exactly that. And, ah…now, you know, uh, Cicero said, “Gifts make slaves.” Okay. You give people handouts — and they become depended, they loose their integrity, they loose their self-reliance, they loose their ability to do anything. Okay. The, the — and they become something less than what they were before. And the space program…if we have a space program, which is just taking handouts — its not being asked to do anything — its going to become something less than it was before and visibly so.

And, while it was debatable whether we should be spending four billion dollars a year on a Shuttle program that was launching six Shuttles to orbit a year — because that really is frankly pretty inefficient, at Shuttles, at, say, 750 million a launch — to launch the same thing a proton could launch at 70 million each — it becomes surreal when one talks about paying 4 billion dollars a year to launch 1 Shuttle, or, no shuttles. Okay? Ah…and…redecorate the pads. Because all you people really care about is the jobs….

“This is not space exploration this not a space program, and you people are not engineers you are welfare recipients.”

The…ah…so…now…the positive side of this…was that it was sufficiently outrageous that it outraged a lot of people.  A lot of people.  People in Congress — people in the President’s own party — Neil Armstrong, who’s been a total recluse for the past, you know, 40 years — came out and said, “I can’t accept this!”  This guy has never said anything. Okay? Um…he came out and said it.

Now…we were…true to form…basically first to denounce this policy. First. I am proud to say. Okay. First to denounce the Augustine policy — the Augustine board was created — John Holdren appointed the Augustine, appointed members of the Augustine commission, and they reported to him. He told them when they gave him the answers he wanted. Okay.

This thing with the flexible path? What’s that?? Flexible path. Let me tell you something, I worked for Norm Augustine at Martin Marietta Company.  And he did not believe in the flexible path then. He did not believe in having programs have no schedules. He did not believe in programs having no specific goals. This is not Norm Augustine’s management philosophy in anything that he actually cares about.

So to say that this is the program that the Space Shuttle — that the space program should adopt: no concrete objectives, no concrete goals, “work on interesting things and let us know when you are ready to do something”…okay…sure…”we’ll just give you money and you don’t have to do anything, by any particular time.” No. This is a put up job. I denounced it in Space News as a Path to Nowhere when they were basically enunciating it, and then of course when the administration came out with it as their policy.

But now, we have allies. We have allies precisely because the policy is so bad. Okay…ah.  They have outraged so many people, and that has created flux in the situation. If they had just come out with something that was half bad — we would have been left isolated. The…a lot of people would have said, “I guess that’s okay, that’ not too bad, let’s move on…” but no, it’s been too crazy.

So we have first the Senate committee and now the full Senate — dominated, almost 60 percent by members of the President’s own party — pass, okay, a…authorization bill that…completely contradicts the administration’s policy. Says, “No! It is wrong! We are not doing it!” Okay…ah…now…unfortunately…okay, it compromises. Because…well, you know, “they’re saying we get nothing, we’d like something, something is better than nothing…and we’re willing to compromise.”

But still, they’ve got a bill in there with money to develop heavy lift. We have to get that to pass. Okay. We have to deliver this defeat, okay, to the Obama administration, and, ah, let them know what the score is. That they can’t just take a major American institution — that, even more than an institution — a symbol, of a great American value. The pioneer spirit.

You know…we went to bat for Hubble against Sean O’Keefe. And it wasn’t just that he was willing to destroy 4 billion dollars worth of the tax payer’s property — which was criminal — but, that he was, undermining — abandoning — two or three critical things. One, NASA as an organization committed to the exploration of the Universe, when they’re abandoning their premiere instrument, their premiere project. Abandoning NASA as an embodiment of the pioneer spirit. –I mean, after all, how’s NASA ever going to the moon or Mars if it is afraid of ever going to Hubble? “This is too risky for us.” I mean, this was the explicit reason: it is too risky for us. Literally, the excuse was: fear. And to say this is the level of timidity at the leadership that was accepted — the philosophy — of an organization which is supposed to be committed to exploration. Okay? And then that takes you to the broader issue — well, two broader issues: which is, the value of the search for Truth and the commitment to…Courage.

Courage is a virtue. Okay? It’s one of the four classical virtues. Justice, courage, wisdom, moderation. Those are the four virtues. Christians add faith, hope, and charity. But these are the four virtues of the Ancient Greeks. And this — Courage — is a fundamental virtue. It is a virtue, without which, none of the other virtues are operable. It is arguably the most important virtue. Okay…it does no good to be Just, if you lack the courage to do Justice. It does no good to be wise, if you lack the courage to do what you know you should do. And so forth. –He was willing to abandon that.

And then finally — Hubble — it is not just a scientific achievement, it is a symbol, of humanity’s commitment, to the search for Truth. It is in a sense the most noble artifact of the 20th Century. It is for us what the Gothic cathedrals were…to…the people of the high Medieval ages, to symbolize their most highest ideals and the aspirations of that civilization. This is the greatest thing for us. You know, people five hundred years from now are not gonna look at our paintings from this period of time — Jackson Pollack — I tend to doubt very much they will think very much of our popular music. And they won’t care at all about our various geo-political struggles among nations — most of which will no longer exist, in their current forms. But they will look at Hubble, and the images it brought back of the Universe, and say, “These people were noble.” –And he was going to abandon that.

And similarly, NASA, as the human space flight program — as an institution — is not merely what it does…okay…because frankly, except for Apollo and Hubble it hasn’t done that much. Okay. But…it’s…it is what it stands for in terms of defining who we are. It’s about who we are. Okay? That’s what it is. That’s why Americans support NASA — fundamentally — it’s not the weather satellites…it’s not the reconnaissance satellites…it’s to some extent — they do like getting back the images of the Mars Rovers and things…and they are curious about some of the answers we’re getting, and they’re hopeful about opening up a new frontier in space, yes…but ultimately it is about who we are.

Yes, we do this because this is who we are — and frankly, this is who we have to be if we are ever going to open the space frontier. So, what you had here, was, an attack on not just NASA but on the American identity. The identity of the pioneers of a frontier. Okay. The…um — so it’s got to be repelled.  With, losses to the enemy. So this is the immediate crisis. I think we can win it. We won Hubble — we were the first people to stand up for Hubble, except for astronomers. “Oh you’re astronomers, of course you want a stupid telescope.” Okay…we were the ones who said, “okay, there are issues here that go way beyond the issues of Mikulski’s district.”

This is about who NASA is — this is about who America is. And this is about — this is not just about — you know, Ares 1.  I don’t care about Ares 1.  You know, frankly I was never that enthusiastic about it — I thought Orion was oversized…it should have been sized down to fit on an Atlas Five, which we have. And so on…you can make all sorts of criticisms like this — but ultimately, they didn’t say that…they didn’t rationalize or try to improve Giffin’s argument…they just said, “This is not who we are.” Okay. Umm…well…it’s got to be who we are…we’ve need to win this.

We’ve got to do what we’ve done on several occasions in the past — which is to take the trouble and go and meet with Congressmen in their home offices…and this is entirely possible to do…and talk to them about this. The bottom line is…NASA needs to have a goal…a goal that is proximate enough to give meaning to its activity…that goal should be Humans to Mars. And the first and most critical — ah, piece of technology that needs to be developed, that is, heavy-lift. Okay. The, the, the — and, and the Senate bill has the money to do it. So, bottom line is, we want you to support that. We go in there and give briefings to Congressmen and they ask us, “What do you want us to do?” –That is what we want you to do. That’s what we would like them to do now.

We’d like them to go further — sure. We’d like them to be champions for our vision — okay, of course…this country needs to set its sights on Mars…we need to embrace the challenge that has been staring us in the face since 1973 and which we have largely shirked. Okay. We need to do that. Okay, we — I mean look, we have everything we have because of our predecessors who had the guts to come across an ocean and build a civilization in the wilderness. A Grand Civilization. Which, not only includes a continental nation committed to liberty — and, whose bayonets have held up the sky for liberty around the world for the past half-century — but, a place that tens or hundreds of millions of people have come to realize liberty for themselves. A place which has demonstrated liberty to the world, so that its fundamental values have been emulated around the world — and laid out the future for humanity in that respect. A place whose inventors have created the modern world — because — it is a place that embraces challenges in all areas, okay, a county that was responsible for inventing electricity, and the telegraph,and the telephone — and I might add, two inventors who came from Ohio: Thomas Edison, who was born here, and of course the Wright brothers, who gave us flight, and gave us motion pictures, and all kind of things — and, furthermore, made the statement that: progress is good, and, that there are no barriers, to a people who embrace challenge in this way — and are wiling to not accept that things are impossible. Okay. Flying. Flying into the air, flying to the moon.

We chose Dayton because as different as the Wright brother’s accomplishment is from the Saturn Five they were both at least in one sense completely emblematic of the same thing — I mean, human flight, realizing an age old dream, reaching for the moon. They were two things which were considered emblematic of what was impossible. They were age old expressions of what was an impossible thing. Okay. And one was invented here, the other was piloted by a guy born here. But — this is the values we’ve got to defend, okay; this is…the message that counts.

And..you know…we are not that many people, but, um, all great things start as little things, all great movements start as small movements. Okay, and, it is…the advocates of ideas — which are not generally accepted — who are those who move humanity forward. Those people who are content with the world as it is, leave the world as it is.

So we have a critical role, as small as it is, as modest as our financial resources might be — we nevertheless represent an idea, which is coming to be as powerful a dream as humans flying in the air once was. The — not just the Freedom of the skies, the Freedom of the Universe. The Freedom of a society fundamentally without limits. That is not limited to one planet — that has before it this enormous prospect of an infinite universe of worlds. The Beichman Group is going to give their results in January — my guess is they’ll report hundreds of planets.  These won’t be Earth-like yet because they’re too close to their sun — but a year later, when they’ve had more time and the planets can go longer periods, there’ll be more and more and more.  We live in an infinite universe of worlds — and, the ability to show then, that these are attainable…that…ah, that they are not an infinite universe which is out of reach, but an infinite universe which is fundamentally within reach.

This is ultimately what the significance of Mars is: that we do not live in a limited universe of limited resources where human aspirations need to limited to conform to such limits, and various regulatory authorities need to be empowered to enforce the acceptance of such limits, and so forth; but rather: we live in a world of infinite possibilities, where, rather than human existence needing to be preserved by suppressing human aspirations and humanFreedom, rather human existence can be enhanced to the greatest by endowing as many people as possible with Freedom and the skills and education required to use it. And ultimately everything hinges on this. Everything. The issue here is — I’ve commented on this in the past, but I just need to restate it. This thing is more important than Mars colonies, as such — as important as they may be. This thing is about the general view of the future people now have. And the general view of the future that the people now have will determine their actions not in the future — but today. 

Is it a good thing or a bad thing that the sons and daughters of Chinese peasants are going to college and becoming scientists and engineers? The person who says, it is — that there are limited resources in the world, says that is bad. That development of countries like China and Egypt should be surpressed — “because these people are going to be as rich as us, they’ll be as educated, they’ll have automobiles and they’re going to use resources and oil and all this stuff and we’ve got to do everything we can to screw them up. Okay. So they do not get what we have.” Okay. On the other hand…if you believe, that, the resources accessible to humanity are determined only by our creativity then you say it is a wonderful thing that the sons and daughters of Chinese peasants are becoming scientists and engineers. Okay. Because right now, America with four percent of the world’s population, is creating half of the inventions in the world.  And — as honorable as that may be, and as proud as an American I may be of that fact — that is not a good thing, that is a bad thing.

Human progress is being slowed down by the fact that most of the world — the potential — of most of those people to make contributions to progress is limited, by their lack of development, and by their lack of freedom. And — the…it would be a great thing for us — just imagine all the progress there could be, and the advance of the human condition there could be — if all these people all over the world who are now unable to contribute to progress, because of their circumstances, were.

So, at that point you say, “Well, we’re friends with the Chinese. We don’t need to go to war over oil — or try to wreck their economy, or them viewing us as trying to wreck their economy. This goes both ways by the way…I mean, these views, they become global. If everyone believes that resources are limited — you have a world in which every Nation is the enemy of every Nation, every race of every race, and ultimately every person of every person. Every new baby born in the world is a new enemy because it’s going to eat something you want to eat. Okay…its a world of hate, and tyranny, and ultimately its a world of war.

If, on the other hand, people understand, that, wealth is not something that exists in the ground — it’s something that’s created with our minds. That human beings fundamentally are not destroyers but creators…then, every nation is ultimately the friend of every nation, and every race of every race…and ever new person born into the world is not a threat but a new friend.

And this is the mental framework which will determine whether we make the 21st Century the greatest era of human progress or a century of hell. That’s the choice before humanity, our specific role…is to use, the Mars Project, to demonstrate, once again, the virtue of humanity. Thank you.

I think I’ll close it…if you have questions for me I’ll just hang out in the lobby.  Thanks for coming, see you all in Dallas next year.

Curiosity and Cameron

“I think any kind of exploration should always try to acquire the highest level of imaging. That’s how you engage people — you can put them there, give them the sense they’re standing there on the surface of Mars.”

.
For obvious reasons the pro-active visionary heroics of Oscar-winning director James Cameron have become a running theme on this blog. The director of “Avatar” and many other sci-fi flicks, “Titanic,” and technologically demanding undersea documentaries, is now helping NASA develop a high-resolution 3D camera for the next Mars rover, SUV-sized Curiosity, due to launch in 2011.

.
Remember the beautiful Mars imagery NASA’s Mars rover, Spirit, captured during its journey to the Red Planet? Now imagine high-definition color 3D video from the surface of Mars at eye-level, in motion, at walking pace: sunrises and sunsets, stars after midnight, vistas stretching for miles.

.

Zoom lenses will allow for “cinematic video sequences in 3-D on the surface.”
.
“The fixed focal length [cameras] we just delivered will do almost all of the science we originally proposed. But they cannot provide a wide field of view with comparable eye stereo. With the zoom [cameras], we’ll be able to take cinematic video sequences in 3D on the surface of Mars. This will give our public engagement co-investigator, James Cameron, tools similar to those he used on his recent 3D motion picture projects,” said Michael Malin of Malin Space Science Systems, Inc, the company which developed the Mastcams.

.
“[NASA Administrator Bolden] actually was really open to the idea.  Our first meeting went very well. It’s a very ambitious mission. It’s a very exciting mission. (The scientists are) going to answer a lot of really important questions about the previous and potential future habitability of Mars.”
.
“We so desperately need not to blow it,” Cameron said of the first opportunity in decades to consider moving human exploration beyond low Earth orbit. Cameron has lamented that space exploration stalled — because of political compromises — after the Apollo moon landings. Rather than being a jumping off point to future great adventures, the space shuttle and International Space Station ultimately “formed a closed-loop ecosystem for self-justification.”
.
Now, the agency has a chance to move beyond that and chase mankind’s “greatest adventure” — landing humans on Mars.
.
“Where does the money come from? From working people, with mortgages and kids who need braces. Why do they give the money? Because they share the dream.” They need reasons to stay engaged: from telling them the ways space exploration has provided them with tools that improve their daily lives to helping them to be more interactively involved in the missions.
.
NASA’s focus has been on hardware instead of people, partly because the agency shields its people from the public. Instead, in an era when American kids and adults need inspiration, NASA needs to do a better job of selling its astronauts and scientists as heroic people.
.
“Our children live in a world without heroes,” he said. “Your kids need something to dream about. We need this challenge to bring us together.” I think that any kind of exploration should always try to acquire the highest level of imaging. That’s how you engage people — you can put them there, give them the sense that they’re standing there on the surface of Mars.”
.
“The [1997] Sojourner Rover became a character to millions of people, a protagonist in a story. How long is it going to survive, could it perform its mission? It wasn’t anthropomorphic in any way, there was absolutely no emotion in a little solar powered machine that was being commanded from eighty million miles away, and yet people thought of it as a character. The reason we thought of it as a character is that it represented us in a way. It was our consciousness moving that vehicle around on the surface of Mars. It’s our collective consciousness — focused down to that little machine – that put it there. So it was a celebration of who and what we are. It takes our entire collective consciousness and projects it there – to that point in time and space. That’s what the Sojourner Rover did.”
.
“I was involved in a private company that was going to try to land two rovers on the Moon. That collapsed in the dot com crash – they ran out of money. I’m loosely involved with people who are going to be doing future robotic missions to Mars. I’m involved in terms of imaging, and of how imaging might be improved in terms of story telling. I’ve been very interested in the Humans to Mars movement –the ‘Mars Underground’ — and I’ve donea tremendous amount of personal research for a novel, a miniseries, and a 3-D film.”
.
Mars is real, non-threatening, a living character with which humanity must become familiar and comfortable. Stay tuned for a forthcoming post explicitly about Cameron’s Mars film work, yet again.

Going Nowhere: Give NASA the Destination MARS!

From an essay in the Spring 2010 print edition of “The New Atlantis,” an article titled Going Nowhere by Robert Zubrin, President of the International Mars Society:

“The shuttle-era record is [not] impressive; it resulted in no new technologies of importance and reached no new destinations — despite the fact that the agency’s budget for the past twenty years has been approximately the same, in inflation-adjusted dollars, as that which it enjoyed during the Apollo period. In the Apollo Mode, NASA’s efforts are focused and directed; in the Shuttle Mode, the space agency’s efforts are random and entropic, shuffling along without a purpose, always buffeted by political winds.

Without the guidance supplied by a driving mission, under the new Obama space policy, another ten years and more than a hundred billion dollars will be spent by NASA’s human spaceflight program without achieving anything significant. We may take part in another twenty flights to low-Earth orbit, but there is no new world there to explore. Together with the Russians, we have already flown there some three hundred times over the past half-century. Spending a king’s ransom to raise that total to three hundred twenty hardly seems worthwhile.

But it must be remembered that NASA’s average annual budget from 1961 to 1973, during the years when the agency flew all the Mercury, Gemini, Apollo, and Skylab missions, as well as scores of lunar and interplanetary probes, was about $19.7 billion (converted to today’s dollars). That figure is very close to NASA’s current budget.

Mars is the closest world that truly has the resources needed for human settlement. For our generation and those that will follow, Mars is the New World.

Four decades of stagnation in space is enough. If any progress is to be made, a course must be set. Leadership is required. President Obama should reject the timid proposal his administration floated in February, which would mark the end of the American human spaceflight program, and should instead take the side of audacity and hope — by committing NASA to reach for Mars in our time.”

Note the Destination Boring People Advocate…Isaac Asimov debate at the Hayden Planetarium (thanks to Landmark Pictures)

Factual corrections to points made by Paul Spudis: eight week round-trip missions to NEAs have been proposed (see earlier posts on this blog); most asteroids rotate at very, very low speeds; most do not have “co-orbiting clouds of debris;” resources will be collected at asteroids and processed in artificial ‘gravitational’ environments at LEO.  These are exciting, solvable engineering challenges.  Solvable.

Bob Zubrin:
“From a technical point of view, we’re much closer today to sending humans to Mars than we were to sending men to the Moon in 1961. […] While there are resources on the moon there are vastly more on Mars. There’re continent sized regions on Mars that are 60% water in the soil. There’s complex geological history which has created mineral ore. There’s carbon, which is necessary for life and for plastics. There’s nitrogen. There’s a twenty four hour day. […] The reason why it is important to do something as hard as exploring and ultimately settling Mars, is because of what it would do for opening up and creating the prospect of a human future with an open frontier rather than a limited frontier of a world of limited resources, in which choices are becoming ever closer and smaller and freedom is ever more limited.

“As far as robots versus humans despite the fact that I am a robot guy, you can’t send humans out to explore the solar system soon enough — for me. As an example, what our magnificent robots have accomplished for six years on Mars — Paul is a geologist — Paul and I could’ve done it in about a week. Okay? So robots fall far short of what you can do with humans. […] I firmly believe the best exploration and the most inspiring exploration can only be done by humans. […] Asteroids have very low gravity so you don’t have to go down into a gravity well and come back out again. There are asteroids that are incredibly rich in carbon, there are asteroids that are incredibly rich in metalic minerals: iron, nickel, and all sorts of trace elements. So everything Paul Spudis is talking about on the moon, you can get it better on an asteroid. Asteroids are an incredibly rich source of raw materials. […] There’s a lot more to mine on asteroids than there is on the moon.” 

If Lunar advocates were at a bar they’d drink alone. Soda. After having attended several space-related conferences each year for over a decade, one characteristic of moon-first advocates which has been unfailingly predictable: they are boring as hell.

James Cameron…Lone Voice in the Wilderness

James Cameron, the writer and director of “Avatar” and “Titanic,” served on the NASA Advisory Council from 2003 to 2005, and has led 6 deep ocean expeditions.  He is currently a co-investigator on the Mars Science Laboratory Mastcam team and a lifetime member of the Mars Society.  (This commentary also appeared in the February 5 edition of the Washington Post.)

Rockets Run on Dreams

.
What do rockets burn for fuel? Money. Money that is contributed by working families who have mortgages and children who need braces. And why do the American people support our efforts in space? Because they still believe, to some extent or another, in that shining dream of exploring other worlds. So it could be said that rockets really run on dreams.

.
The exploration of space is the grandest adventure challenging the human race. As a filmmaker I have celebrated this greatest of dreams in my movies and documentaries, and I remain as passionate about the discoveries ahead as I was when I was a kid. So it was with some trepidation that I waited for the NASA budget to be unveiled this week. I was concerned that amid the nation’s fiscal crises, space exploration would fall off the priority to-do list. But the new NASA budget reveals a pathway to a bright future of exploration in the coming years. It simply reflects the deep changes and hard decisions necessary to accomplish that goal.

.
Last year President Obama instructed the Augustine commission to report on the likely prognosis for NASA’s exploration activities. After months of study, the conclusions the panel released last October were gloomy. The Constellation program, implemented in XXX and designed to put humans back on the moon by 2020, could not possibly succeed within that timeframe or for the budgeted amount, it reported.

.
In response, the president and NASA have crafted a bold plan that truly makes possible this nation’s dreams for space. Their plan calls for the full embrace of commercial solutions for transporting astronauts to low Earth orbit after the space shuttle is retired next year. This frees NASA to do what it does best: deep space exploration, both robotic and human. By selecting commercial solutions for transportation to the International Space Station, NASA is empowering American free enterprise to do what it does best: to develop technology quickly and efficiently in a competitive environment.

.
As Peter Diamandis, chairman of the nonprofit X-Prize foundation, said in a recent blog, “The U.S. government doesn’t build your computers, nor do you fly aboard a U.S. Government-owned and -operated airline. Private industry routinely takes technologies pioneered by the government and turns them into cheap, reliable and robust industries.” When the shuttle is finally retired after more than three decades of service, the United States will be dependent on the Russian Soyuz to get our astronauts to the International Space Station, at a cost of $50 million per person. But under the new NASA plan, private industry will take over this capability within a few years, much more quickly than Constellation would have, and at a competitive price.

.
The money saved will be plowed into research and development of robotic explorers that will act as precursors and technology demonstrators, paving the way for human exploration of the moon, asteroids and Mars. Additional funding has been committed to the development of advanced propulsion technology, which can bring down the cost of spaceflight. And the space station’s lifespan will be extended several years, which in turn will increase the science yield and satisfy our international partners. This international cooperative effort is important as a model for how future large-scale missions will be organized and funded. In addition, money is being made available to both Earth and planetary science, which can help us understand climate change on our own world and the alien processes at work on some of the other worlds in our solar system.

.
Over the past 15 years, I have gotten to know a lot of people at NASA while working on projects to advance space and ocean exploration. I’ve found that many, if not most, started as starry-eyed childhood dreamers. Maybe they loved science-fiction stories, with their promise of alien worlds, or maybe they were geeks like me, peering through a telescope in the back yard until their moms yelled again for them to come inside, “it’s a school night!” They grew up to become engineers, brilliant planetary scientists and steely-eyed missile men, who collectively have pushed our human presence out to the moon and our robotic presence not just to Mars but to the outer reaches of the solar system. I applaud President Obama’s bold decision for NASA to focus on building a space exploration program that can drive innovation and provide inspiration for the world. This is the path that can make our dreams in space a reality.

New York Times Favors MARS FIRST!! $&%# the $*&@ Moon!

In its lead editorial February 9, the New York Times called on the Obama administration to make human missions to Mars the goal of the American human spaceflight program. A complete discussion of the current political situation and potential initiatives for dealing with it will be held at the 13th international Mars society convention, August 5-8, 2010, Dayton Mariott, Dayton, Ohio. Registration for the conference is now open at www.marssociety.org.

Commenting on the administration’s new space policy released February 2, the Times said:

A New Space Program

February 8, 2010

President Obama has called for scrapping NASA’s once-ambitious program to return astronauts to the Moon by 2020 as a first step toward reaching Mars. That effort, begun by former President George W. Bush, is behind schedule and its technology increasingly outdated.

Mr. Obama is instead calling on NASA to develop “game-changing” technologies to make long-distance space travel cheaper and faster, a prerequisite for reaching beyond the Moon to nearby asteroids or Mars. To save money and free the agency for more ambitious journeys, the plan also calls for transferring NASA’s more routine operations — carrying astronauts to the International Space Station — to private businesses.

If done right, the president’s strategy could pay off handsomely. If not, it could be the start of a long, slow decline from the nation’s pre-eminent position as a space-faring power. We are particularly concerned that the White House has not identified a clear goal — Mars is our choice — or set even a notional deadline for getting there. The National Aeronautics and Space Administration and Congress need to keep the effort focused and adequately financed.

The most controversial element of the president’s plan is his proposal to scrap NASA’s mostly Moon-related technology programs that have been working to develop two new rockets, a new space capsule, a lunar landing capsule and systems for living on the lunar surface. Those efforts have been slowed by budgetary and technical problems. And at the current rate, the Moon landing would likely not occur until well after 2030. The technologies that looked reasonable when NASA first started in 2005 have already begun to look dated.

A lunar expedition would be of some value in learning how to live on the Martian surface but would not help us learn how to descend through Mars’ very different atmosphere or use that planet’s atmospheric resources effectively. Nor would it yield a rich trove of new scientific information or find new solutions for the difficulties of traveling deeper into space.

The president’s proposal calls for developing new technologies to make long-distance space travel possible: orbiting depots that could refuel rockets in space, lessening the weight they would have to carry from the ground; life-support systems that could operate indefinitely without resupply from Earth; new engines, propellants and materials for heavy-lift rockets; and advanced propulsion systems that could enable astronauts to reach Mars in a matter of weeks instead of roughly a year using chemical rockets.

Leaping to new generations of technology is inherently hard and NASA’s efforts may not bear fruit in any useful time period. To increase the odds of success, Congress may want to hold the agency’s feet to the fire and require that a specified percentage of its budget be devoted to technology development.

The idea of hiring private companies to ferry astronauts and cargo to the space station is also risky and based on little more than faith that the commercial sector may be able to move faster and more cheaply than NASA. The fledgling companies have yet to prove their expertise, and the bigger companies often deliver late and overbudget.

If they fail or fall behind schedule, NASA would have to rely on Russia or other foreign countries to take its astronauts and cargoes aloft. That is a risk worth taking. It has relied on the Russians before when NASA’s shuttle fleet was grounded for extensive repairs. It would seem too expensive for NASA to compete with a new rocket designed to reach low-Earth orbit — far better to accelerate development of a heavier-lift rocket needed for voyages beyond, as NASA now intends.

The new plan for long-distance space travel also needs clear goals and at least aspirational deadlines that can help drive technology development and make it clear to the world that the United States is not retiring from space exploration but rather is pushing toward the hardest goal within plausible reach.

We believe the target should be Mars — the planet most like Earth and of greatest scientific interest.

Many experts prefer a flexible path that would have astronauts first travel to intermediate destinations: a circle around the Moon to show the world that we can still do it; a trip to distant points where huge telescopes will be deployed and may need servicing; a visit to an asteroid, the kind of object we may some day need to deflect lest it collide with Earth. That makes sense to us so long as the goal of reaching Mars remains at the forefront.

At this point, the administration’s plans to reorient NASA are only a proposal that requires Congressional approval to proceed. Already many legislators from states that profit from the current NASA program are voicing opposition. Less self-interested colleagues ought to embrace the notion of a truly ambitious space program with clear goals that stir all Americans’ imaginations and challenge this country’s scientists to think far beyond the Moon.
