of future space programs, I would like to present three

so-called "alternative futures", not just for the United

States, but for the world. I think which future becomes

reality may depend to a surprisingly significant extent

on what is decided in the near future by the relatively

few members of this committee (compared to over 4,000 million

members of the human species). It is perhaps appropriate

that this question originates in the House of the people

rather than with the Senate, the President, or even the

United Nations.

One possible future is for NASA to continue at its

present more or less subdued pace. In light of the testimony

at these hearings "spelling out" the great opportunities

space offers to industry, employment, and the human condition

this approach is clearly irresponsible and will not be

discussed further herein.

The other approach, then, is for NASA to quicken its

pace

perhaps, for example, taking a realistic and flexible

2

step-by-step approach such as that previously detailed
in these hearings by Gerard K. O'Neill or G. Harry Stine.

The real question in my mind therefore becomes whether

we will treat the so-called "high frontier" program as a

space program or a people program. By "treating it as a

space program", I mean looking at it from a narrow technological short-run point of view which no doubt will aid industry, increase employment, and probably improve the human condition and devoid of any overarching long-term ethical (rather than technical) goal. I propose a more comprehensive human long-term "high frontier" program with an explicitly stated

overall ethical goal and time table to strive for.

Does it really make much difference whether we take

a "space program" or "people program" approach? I suggest
it may be one of the most important decisions in the history

of the human species.

It is not often we get a chance to eliminate all human

poverty and end all war. Specifically, for the first time in human history we now have via space and space science

the practical means to acheive what the social scientists

have only speculated about. We may not get another chance

in centuries, if ever. There are realistic reasons why we

can stop spreading poverty and war beyond our tiny planet

when we have been unable to end it aboard ship. As urban

planners have noted

it would be easier to build a new

3

city rather than have to work with a decaying old one.

Re "fighting" the population problem and giving "utopia" (democracy) a fair chance, the settling of America (not

merely the slow evolution of Europe ) was the road (unconsciously)

taken. The difficult job of settling the American frontier

seemed to a lot of people at the time to be a silly, nutty

idea. The United States has been called the first new nation,

And because we were new, we could idealistically but perhaps

for the first time realistically give our ideals a fair
( "neutral") chance. At the time, the miraculous results
greatly surprised a large number of supposedly intelligent

level-headed people.

But we have come a long way in 200 years. The question

today is not whether a non-democratic government is a necessary

evil. Democracy was very idealistic

but perhaps it needed

a new land, a new frontier, to also prove itself realistic.

Today the question is whether we will end all human poverty

and war. With only a few exceptions, space scientists admit

that technologically we theoritically can end all human

poverty via "the high frontier", possibly by the mid-21st

century

There are no doubt various space programs (past, present,

future) which are exceedingly justified. These programs

are not discussed herein. The program herein under discussion

should more properly be viewed as a people program, not

[ocr errors]

a space program. A few points to keep in mind about this

program:

1. Whether the program costs $50 billion or $500 billion

(how does one put a price on ending all human poverty and

war?), once the initial development (say, a few decades

at most) is done

no further funds will be required.

The space habitats will be entirely sef-sufficient, will more than pay for themselves, and will without any additional

funds manufacture more and better habitats.

2. The habitats will eventually prove to be not only

Earth-like (grass, trees, etc.) but even better than
Earth (no pollution, complete control over environment, etc.)
They will be homes in space, not "space capsules".

3. Eventually, but, likewise, in the foreseeable future

(before the mid-21st century, if we so decide now)

millions,

even billions (not just thousands) will be living in space.

4. This "people program" will greatly improve the

lives of people on Earth re employment, energy (directly or indirectly), population, resources, and environment.

5. The space habitats may to some extent decrease

the felt need of people or nations to "steal" from another.

6. The space habitats will allow-encourage social

diversity and experimentation, including ethical and existential evolution of the individual.

7. To be successful, the program will have to be multi
