In Defense of Space Exploration
MIT-TECH ^ | January 29, 2004 | Matt Silver

Posted on 01/28/2004 9:33:24 PM PST by Cincinatus' Wife

While many in the MIT community are likely thrilled by President’s Bush’s newly announced initiative to return men to the moon, others remain more skeptical. Echoing arguments voiced this week by Democratic hopefuls in New Hampshire, some cynically suggest that, among other things, the plan is an election-year gesture, it will cost too much money, our national resources and attention should be focused on other areas (such as health-care), and that, in short, the gains from human space exploration are really not worth the effort. While such rhetoric may sound good on a campaign platform, it ignores the details of the initiative and overlooks both the tangible and intangible benefits that exploration provides. Let’s take a moment to review both the plan and benefits of space exploration in general.

First, is this an election-year stunt? The simple answer to this question, unless one puts party politics before national interest, is: who cares? Let us determine the merit of the plan based on its substance, not based on who articulated it.

Regarding cost, let’s put some things in perspective. NASA’s FY03 budget was roughly $15.5 billion. The Bush initiative calls for $1 billion in new funds spread over the next five years, and $11 billion re-allocated from existing NASA programs, resulting in an increase of $200 million a year. For comparison, the U.S. will spend roughly $400 billion on defense in 2004 -- more than the next fifteen countries combined. Congress has recently tabled the $328 billion Consolidated Appropriations Bill for FY04, which includes no less than $10.7 billion in earmarks. These are funds dedicated to particular congressional districts, often benefiting little more than a specific congressmen’s election effort. California will soon have a “bus project for Mickey Mouse at Disneyland in Anaheim,” courtesy of Uncle Sam. I hope the implication is clear: if federal over-spending worries you, the $200 million NASA initiative should not be your first concern.

Those opposed to space programs will here point out that federal over-spending in one area does not justify it in another. There are many reasons, however, why that increase and the plan that goes with it constitute wise resource allocation. First, the initiative opens the possibility for much needed change at NASA. The Columbia tragedy threw light on major internal and organizational problems at the agency. The Columbia Accident Investigation Board report describes the tragedy not as an isolated incident, but as symptomatic of a broken safety and management culture in which innovation and safety often take a back seat to bureaucracy and political infighting. The bold mandate for an $11 billion internal re-organization coming from the highest levels of government will finally give NASA headquarters the authority to cancel unnecessary programs, streamline operations not consistent with the stated goal, and override political pressure that otherwise stifled change. In short, an increase of $200 million a year will greatly improve the current $15 billion annual investment in space exploration, and give NASA much-needed direction. I’m not sure the bus project at Disneyland gets the same bang for its buck.

Some, of course, maintain that the U.S. should simply not be involved in human space flight to begin with. This brings us to the classic argument of whether human space exploration in general is a good thing, worth reviewing in light of the current plans.

First, money spent on space research and development does not disappear into thin air. It goes toward creating knowledge, jobs, new businesses, and technologies, many of which have direct application to other activities. This is the spin-off argument. A moon initiative will require increased sophistication in, to name a few areas, solar-power generation, cryogenic technologies (cooling and storing liquefied gas), and human-robot interaction. These advances in the state-of-the-art will benefit energy, environment, health care, and many other areas. Many of the capabilities required for human exploration are synergistic with defense needs. Bush’s initiative will likely lead NASA and the Department of Defense to pool resources, lowering development costs for both agencies.

There will also be important scientific returns. The NASA Hubble Space Telescope has literally changed our understanding of the universe. A telescope on the moon, shielded from both solar and earth radiation, has the potential to see further into the universe than anything previously built. During the Apollo moon landings, we arguably learned more about lunar geology and the solar system in general than we could have in many decades of robotic probes. This kind of science merits government funding.

An often-ignored benefit of space activities involves its capacity to increase international cooperation and generate goodwill. A return to the moon will bring the international community together in an activity that pits man against the cosmos. An international effort will not only lower costs through the pooling of resources, it will create concrete links between the U.S., Russia, Japan, Europe, even China; and this will have tremendous symbolic over-tones.

Last, but certainly not least, while space enthusiasts often point somewhat apologetically to the benefits described above in order to justify space exploration, there is a deeper reason for their fascination. It is the same reason that gives space exploration its great symbolic weight -- the innate human desire to learn more, to see more, to explore the unknown. While this need does not easily find its way onto a budget sheet, it has an important place in society.

Stanford historian Wyn Wachorst has noted that the mythic and poetic possibilities unearthed by the space programs of the 20th century have changed us forever. Some argue that the imagery of the Apollo program -- the Earth floating above the lunar surface in a sea of black -- sparked a sea change in society that eventually resulted in the environmental movement. Exploration serves a purpose. It expands our awareness and conception of the possible. It reminds us with unparalleled immediacy that, after all is said and done, life is about more than the sum of our budgets, and that there is more to know.

Money should be spent on health care and means-tested social programs, and hundreds of billions of dollars each year are. But an important point often eludes those who argue adamantly that every last nickel should be spent on such programs: major advances --advances that benefit all humans -- rarely occur if society itself does not grow, and this can only be achieved if while we look inward at the problems before us, we do not forget to look outward and take some risks.

Virtually all we have learned from space we have learned from unmanned space vehicles. Putting man in space has taoght us almost nothing. Send more Rovers everywhere.

The robots can only tell us what they are programmed to tell us. That may be allot, but it's not the whole story.

Imagine the moon landing - without the people, using only the technology of that time period. The impact on mankind would have been what?

I think we are missing out on things on mars for the same reason, the robot has no imagination or intuition and the human kind is not intimately connected to what it does.

The current round of probes can not pick up a rock of any size and look at what's underneath it. It can't toss a stone and marvel at how it flies in the lower gravity. It can't feel the sand or relate what its surrounding to anything on earth. The cameras will only show so much, a man could see more, from more perspectives in several seconds than the probe can see all day.

We are missing allot by not being there, just what? There is no way to tell until we go.

The ability to put people in space can be a very useful tool. Likewise the Shuttle's ability to bring large amounts of cargo down from orbit. When those abilities are not needed, however, manned Shuttle missions are a waste of money compared with the cheaper alternatives.

One word...bullcrap.

You obviously have no clue about the technology we have available for this project. If anything, it's too long in it's timetable. We can do a permanent moon base in 5-7 years easy.

You have a computer, Google it...do the research.

To some research.

First, it would be a small contingent of scientist on the moon. Second, they can use fuels cells and tap into the moon's water table (it has one) in the north and near the dark side. These fuel cells would create power and provide oxygen to be mixed with nitrogen tanks for breathable air.

They will move around to the dark side to set up and build a radio telescope that isn't interferred with by Earth/Sun problems. A clear channel out to the universe without the atmospheric interference would be amazing.

A mid-orbital platform between the moon and Earth would be built to manage the transfer of supplies. And it would serve as a future Mars starting point. And they'd send up payloads to build a nuclear engine to get to Mars faster than we do now.

We have the technology and would have even more once the private sector is given contracts to create better ideas.

And it wouldn't cost billions and billions like Apollo or the Space Shuttle. Again, just do some simple research.

Try NASA's website or TechCentralStation.com or Space.com and just read.

I appreciate your concerns, but you are way off. It's much easier than you understand.

Nuclear engines are not expensive. Sending supplies to the moon isn't expensive.

There are already dozens of firms with viable ideas and means if they had funding. $11 billion can do a lot.

I'm an optimist, you're a pessimist so we can agree to disagree on the subject. Again, do some more reading and you'll be surprised. For example, hydrogen/oxygen fuel cells work both ways...you use water to extract the hydrogen and oxygen and then combine them again to create power. It's not much different than the technology they want to use for cars.

Oh, btw, welcome to FreeRepubic. Hope you enjoy the site and contribute often. Goodnight.

You're right. Let's just give up. It costs too much and it's too hard.

With all due respect, those rovers have a tendency to break down - a lot and often. Humans can adapt to new situations and fix broken equipment - think Apollo 13 mission. Contrast this fact with the techies on the ground at JPL trying to jimmy that Erector set / RC car they've got on Mars to even radio home.

Would we fly all our radiation shielding from earth. Would the base use fossil fuels, nuclear or solar.

Dirt is free, makes great radiation shielding and there is plenty of it on the moon.

The best choice would be nuclear for base power. Solar is doable, but would require batteries/fuel cells for the 2 week night.

I assume we will be constructing the mars craft on the moon.

Not anytime soon, and not unless access to space gets much, much cheaper. Yes, at least initially, this will just be the space station in a different place.

It may have ice crystals mixed into the soil at the poles. The soil would have to be processed to retrieve it, non-trivial task at best.

wouldn't it be sweet if we built the first space elevator on the moon, where it can be shorter and used that to get material to a lunar orbit or L1 shipyard and make space colonies and mars ships, and counterweights for earth based space elevators?

oh wait, the moon spins around like once every 2 weeks right? hm, that means it would probably need an even longer space elevator than earth, which is spinning a lot faster.
