Jacob Sullum | September 23, 2005
This week, after announcing a $104 billion plan for returning to the Moon for no particular reason, NASA Administrator Michael D. Griffin explained why money for rebuilding New Orleans should not be diverted from his budget:
There will be a lot more hurricanes and a lot more other natural disasters to befall the United States and the world in that time, I hope none worse than Katrina. But the space program is a long-term investment in our future. We must deal with our short-term problems while not sacrificing our long-term investments in our future. When we have a hurricane, we don't cancel the Air Force. We don't cancel the Navy. And we're not going to cancel NASA.
I am a science fiction fan and space enthusiast who hopes NASA critic Robert Park is wrong when he says "human space exploration is essentially over." But that does not mean I am prepared to force other people to fund my dreams. I see a distinction between the armed forces and NASA that Griffin seems to be missing: The Navy and the Air Force protect us from our foreign enemies, a central function of government for anyone who concedes the legitimacy of government at all, whereas NASA spends a lot of money on projects of dubious scientific value that are supposed to make us feel good. Given the relatively low cost of the unmanned missions that (as Park notes) offer the biggest scientific payoff, and given the emergence of a launch industry for both commercial payloads and space tourists, it seems NASA is necessary mainly to pay for projects that are not worth funding. If we were menaced by invaders from Alpha Centauri, I might change my mind.

If we were menaced by invaders from Alpha Centauri, it'd be a job for the Space Marines - not NASA.
You're fuding the distinction between scientifically valid NASA missions - like Mars Rover - which also aren't as immediately necessary as the Air Force, and boondoggles like the Moon mission.
Do you want to know more?
Seriously, though, just build a space elevator already.
I dunno. Didn't we actually get a lot of profitable and
time-saving technology out of the old space program?
And won't a second push for the moon be much different from the
first? I mean, isn't this kind of like saying it's pointless to
visit Australia twice, since you've already been there once?
"Do you want to know more?"
Watching Doogie splash gore everywhere while dressed in a Nazi-like
uniform was some of the best cinema in the '90s.
When did scientific value ever determine funding priorities. The reason for going to Mars is because someone thought it would sound neat when delivered in a State of the Union address.
My own personal fantasy is private sector space elevators mining
super-atmospheric solar power to convert seawater into hydrogen for
fuel cells, thus making them not just self sustaining but
profitable. Not being a scientist or an economist I have no idea
how plausible this is.
As for NASA, they should be throwing all they've got into an
asteroid detection and neutralization program. The sky is fucking
falling people! Its only a matter of time...
I heard somewhere that the second moon trip will be much more
expensive than the original Apollo program (factoring in inflation,
of course). But I haven't looked into it in detail.
Let's hope the abiogenic theory of oil is correct, cuz if it is
then maybe the moon trip can pay for itself. Yeah, I know, the
theory is dubious, and the expense would never be worth it, yadda
yadda.
Still, you gotta admit, it would be pretty frickin funny to build
oil derricks on the moon. Until the lunar residents start funding
terrorism. Then it would suck.
If we were menaced by invaders from Alpha Centauri, it'd be
a job for the Space Marines...
Heretic! Evey Imperial school boy knows that the Ordo Xenos with
the aid of the Space Wolves and Blood Angles orders of the Adeptus
Astares cleansed Alpha Centauri through the holy rite of
Exterminatus 12 score and 3 years ago!
Who do you serve, traitor! The Eldar? The Tau? Which Chaos lord do
you worship? Stay here while I fetch an Inquisitor!
I'd like to see interstellar "burials" for dead rich people. Blast 'em off and send 'em out of the solar system on a one-way trip to infinity. Sure beats a dirt nap and who knows: maybe someone or something will find them in a few million years. I'm serious.
I wonder if even privatizing space will ever work. The fact is regardless of where you go, you have to make a living when you get there. What could I possibly produce on the Moon or Mars that would justify the resources necessary to put me there? Certainly, scientific research can probably justify the expense. But that can be done by robots or at most a small settlement of scientists. Its difficult to imagine the world ever getting so short of resources or space travel ever getting cheap enough to justify mining it several million miles away. The boldly go where no man has gone before stuff only goes so far. You have to have some economic justification for it and I can't see one ever arising outside a few niche areas like astronomy and tourism.
John-
One can imagine exotic manufacturing processes (especially
chemistry and biomaterials) that might be best done in zero-G. That
could justify orbiting platforms, especially if the orbiting
platforms also pull in tourism dollars. But I'm not an expert on
those zero-G applications.
Hypothetically, one can envision technological advances that might
make asteroid mining profitable, especially if those asteroids
turned out to have have elements that are rare in the earth's
crust. But that's all very speculative.
Mining on the moon or Mars seems much less likely to ever become
profitable, since there's the cost of pulling resources out of the
gravity well.
They should combine the Katrina money and the NASA budget and rebuild New Orleans on the moon. No hurricanes there.
Oh sure, wait until Alpha Centauri invades, and then fund NASA.
It'll be too late, and we'll all be farmed for our water.
Why do you hate Earth?
I dunno. Didn't we actually get a lot of profitable and
time-saving technology out of the old space program?
Plus Tang! You forgot Tang!
Would it not be more efficient to directly fund research into
profitable and time-saving technology, rather than wait for such
technology to emerge as a by-product of space exploration?
If that's the govt's role, that is...
Jacob,
If we were menaced by invaders from Alpha Centauri, I suspect that
it would be ordinary people like Ryan Asmussen from Matt Taibbi's
Katrina dispatch in the post above that would be on the front line
in helping retrieve people from their laser-scorched homes. NASA
and Michael Griffin would be as useless in that scenario as they
are now, but I bet you'd find that the "society of volunteer
rescuers" would get out there and do what needs to be done. Unless,
of course, the space invaders attacked the FEMA headquarters. Then
it's every bureaucrat for himself!
Over the years, I have gone from optimist to downright cynic in
regards to NASA and government funded space exploration. It's not
just the question of funding, but it's also the years upon years of
being told that our return to the moon or a Mars mission was only a
"decade" or so away. Notice how it's ALWAYS a decade away and this
has been going on since the 70s. After a while you can only take so
much until you realize that boyhood dreams of a spacefaring America
are just that, boyhood dreams. Yeah, pretty pictures from robot
probes are fun to trade with your fellow amatuer astronomers, but
there is no romance in sending a machine to do a man's work. No
drama. No opera.
Trouble is, manned space flight maybe one of those ventures that
maybe eternally too expensive for even the free market to handle.
As cool as asteriod mining, o'neil conlones, and diging for H3 on
luna sounds, the costs will proboably never pan out into profits,
keeping serious investors away. I guess I'm going to have accept
living in a world where
God, I hate growing up and having nothing to dream about
anymore.
Whoops, forgot to finish:
I guess I'm going to have a accept a boring world where everyone
has their feet all-too firmly planted on the ground.
I heard somewhere that the second moon trip will be much
more expensive than the original Apollo program (factoring in
inflation, of course).
Well, Griffin is estimating it will be about 55% the
cost of Apollo. How true that will turn out to be is anyone's
guess.
Didn't we actually get a lot of profitable and time-saving
technology out of the old space program?
That's the rumour. Problem is, when you start asking for specifics,
it turns out the many of the technologies that are credited to the
space program actually were developed by somebody else (Velcro,
Teflon, microprocessors, etc.).
One can imagine exotic manufacturing processes (especially
chemistry and biomaterials) that might be best done in
zero-G.
Unfortunately, "imagining" is mostly what you'd be doing. So far no
one has been able to identify a zero-G manufacturing process for
anything that couldn't be more economically replicated on
earth.
I see a distinction between the armed forces and NASA that
Griffin seems to be missing: The Navy and the Air Force protect us
from our foreign enemies, a central function of government for
anyone who concedes the legitimacy of government at all, whereas
NASA spends a lot of money on projects of dubious scientific value
that are supposed to make us feel good.
Not entirely true. If our competetors, such as Russia and China,
are establishing a miliary presence in space, then if behooves us
to acquire the technology to counter them. Of course, right there
you have an argument for folding the space program back into the
military. Which, from the perspective of a space buff, isn't an
entirely bad idea. Look at the budget the military gets, as opposed
to the budget NASA gets.
Unfortunately, "imagining" is mostly what you'd be doing. So
far no one has been able to identify a zero-G manufacturing process
for anything that couldn't be more economically replicated on
earth.
Agreed. My goal was to identify plausible and implausible future
scenarios, not urge anybody to invest right now.
For now, the only profitable uses for space seem to be
communication and observation satellites (and probably some other
satellite uses that I'm not thinking of) and perhaps tourism. Long
term, maybe exotic manufacturing. Maybe. If asteroids yield exotic
minerals and the price is right, one can see that. But mining the
moon and Mars seems very, very unlikely.
Pig: Also look at the neat stuff the military develops, as opposed to NASA. The military might be bloated, but at least they contract with private companies to make neat toys. The M1-A1, the F-22 Raptor, UAVs...look at the progress military technology has made since the early 80s, then look at NASA still flying that damnable shuttle, and tell me who has a better model. But, yeah DoD does get a lot more money, which probably helps them hire the expensive outside contractors.
Pig Man,
"Didn't we actually get a lot of profitable and time-saving
technology out of the old space program?"
"That's the rumour. Problem is, when you start asking for
specifics, it turns out the many of the technologies that are
credited to the space program actually were developed by somebody
else (Velcro, Teflon, microprocessors, etc.)."
Hey now! What about that writes-in-any-position pressurized space
pen? Huh, what about that?
God, I hate growing up and having nothing to dream about
anymore.
Why? You can still dream big government dreams.
Alpha Centauri, eh? If we're very very unlucky, we'll be hit by
Santiago hellbent on revenge and riding mind worms. Or it will be
Miriam who will make all the unconverted undergo nerve stapling
until they see Jesus 24/7.
I'm hoping for Deidre since she'll institute government-sponsored
free love. Of course you guys are boring enough to wish for Morgan
and his uncanny ways of turning even fungal blooms into pure
profit.
I think historically NASA was mostly about getting young U.S.
students interested in engineering, generally. (EG, my father
worked on some arcane aspect of the moon landing, and 20 years
later he talked me into getting an engineering degree -- so there
is one anecdote).
Now that the US can import low cost foreign engineers, there seems
to be a lot less reason for NASA.
The Apollo program gave us spray-on cheese.
And why can't I find any Tang?
If we were menaced by invaders from Alpha Centauri, I might
change my mind.
What if we could win the game
by colonizing Alpha Centauri?
I'd much rather spend the money building bigger and better space observatories. At least they can produce data that helps mankind understand how the universe works. In comparison, going to the moon is like driving 12 hours out of the way to see the country's second biggest ball of twine.
I think the manned space program ought to be turned over to the
Air Force. There may eventually be a need for manned aircraft
capable of defending the US in near Earth space, so let the Air
Force take over that work. (Although even that need may not be
great, since there is a lot of work being done developing unmanned
vehicles.)
There's no need to send humans back to the Moon anytime soon, even
as a stepping stone to Mars. (And there's no need to go to Mars now
at all.) Robots can do most of the work of humans plus some things
humans can't do, so let NASA continue sending robotic explorers
into space. Or maybe even turn that work over to NSF, and convert
NASA back to NACA.
Someday in the far future the Moon may serve as a launching
platform for sending vehicles into deep space, using a magnetic
rail system as Heinlein described in "The Moon Is A Harsh Mistress"
(powered of course by Martin-Douglas Sun Power Screens). Then (and
only then?) will it make sense to try to go to Mars, Jupiter,
etc.
Lots of fun comments here, but this is a serious subject.
1. Exploration always pays off---unless you give up on it. The
Chinese were set to explore the world in the 1200s in huge ocean
going fleets, and then politically gave up on it. If they hadn't,
Columbus would have met the Great Khan of the Caribbean!
http://www.pbs.org/wgbh/nova/sultan/explorers.html
2. It's all about will, not cash. We went from launching things
that weighed maybe fifteen pounds into low Earth orbit to landing
two guys and an electric golf cart on the moon---in ten years. So
it'll take us MORE time NOW? Failure of the will, again, with the
ever-loving press telling us why we can't do things, as
always.
3. Profits in space/robots in space. False argument. We don't know
all we can do. Poke fun at microgravity research if you wish. Look
at how we STILL don't know if there is life on Mars. The robots
have gone and looked, and every one of them needed to do things it
would take a person about five minutes to do. And life on another
planet would tell us a great deal about life on this one. Finally,
being able to protect the planet from asteroid or comet impact is
vital---and we do little about it.
Cash value? If a 100 meter rock hit Los Angeles, how much damage,
and how much to "fix" it all? Now compare it to the money it would
cost to have prevented it in the first place.
It's like folks at my university, who hate to pay for service
contracts...even though fixing the equipment when it is broken is
hideously expensive...they just don't want to pay for the
upkeep!
4. Fools in NASA---of course! They are just looking after their
paychecks. We need vision, not paperwork. Too many bureaucrats, too
few engineers.
5. I like Jerry Pournelle's idea for private industry: offer a cash
prize (like the X-Prize did) for the first company to accomplish a
specific goal: launch three humans to orbit, return them safely,
and do it again two weeks later....and so on. To be honest, it
worked in the early days of aviation!
Sorry for the long post. I had my dreams of space travel stolen by
politics. What are frustrating to me are the negativists and the
politicians.
Thanks for listening...

Well, in response to thoreau, the latest pop-sci for what it's
worth has a story estimating the new moon shot at 100Billion
between now and 2020.
It seems according to that story and others that in fact Nasa is
running two programs in paralell. One that runs the space contracts
the old fashioned way: that is, awarding giant contracts to the
well known aero-space companies based on proposals they submit and
contract bids, and a second program that has private firms
developing technology for their own good and Nasa giving them
grants based on proven successes and meeting certain
criteria.
The first program is designed to replace the shuttle program, and
the second is designed to obtain a cost effective back-up and small
payload vehicle for maitnenance and rescue missions along the lines
of the Soyuz capsule.
In response to linguist:
Yes and no.
Many of our technologies may be owned invented and patented by
private corporations (thank god Nasa has certified that special
sleep foam though) but it is not unreasonable to argue that
companies like Dow, DuPont, et al. would not have devoted research
and resources to those areas of study without the space program and
the potential for profits. Certainly the demand and pay-off for
high strength high temperature ceramics was hugely influenced by
the space prgram.
Unfortunately the latest pop-sci also mentions that the current
lead design for a new crew capsule is extremely similar to the
original Apollo capsules. It seems this mission so far may be an
attempt for NASA to go backwards for a little while to see if they
can figure out where they missed a more promising turn-off.

can figure out where they missed a more promising turn-off.
NASA does have a purpose, but it is very limited compared to the
missions they attempt today. The Shuttle is the piece-o-crap that
it is because the Air Force (in return for giving up their own
space program) demanded something big enough to put spy satelites
into high orbit. That was the right decision for the Air Force, but
a bad move for "Mars Rover NASA".
NASA should do stuff like Hubble and Cassini. That's good science
right there, and there isn't any other government agency with a
clear mandate to do it. Who else would have sent the Mars probes?
No one. If private industry ever feels like enough of the risk has
been sucked out of space ventures to make it worth it, it will be
because NASA trailblazed the way. Government does play a useful
role in such endeavors, as the examples of Queen Isabella funding
Columbus and President Jefferson funding the "Corp of Discovery"
(aka, Lewis & Clark) should demonstrate.
There are a couple things that NASA does NOT need to do. One is the
Space Shuttle. The only thing that's used for today is getting
people to the ISS and back. That's overkill. The Shuttle is
practically a space station all by itself. If we're set on keeping
ISS up there smaller rockets with 4-man capsules will do the job
just fine (see t/Space as an example). For anything that needs a
heavy load (like the Air Force's space hardware), heavy lift
boosters like the Delta IV are a much better way to go. Boosters in
development, such as SpaceX's Falcon, would do the same job for
cheaper.
What REALLY had to go though is NASA's Command & Control
organization and culture. There is simply no reason they have to do
everything in house with hundreds of engineers and thousands of
support staff. That's a 1950's business model, and it has to go. So
does cost-plus contracting. NASA needs to adopt the most efficient
organization model it can, and then constantly improve on it. That
might be asking too much of a government agency, but they'll take
their budget thousands of times further than they could imagine if
they ever do.
I mean, isn't this kind of like saying it's pointless to
visit Australia twice, since you've already been there
once?
well....
It's all about will, not cash. We went from launching things
that weighed maybe fifteen pounds into low Earth orbit to landing
two guys and an electric golf cart on the moon---in ten years. So
it'll take us MORE time NOW?
Just as the atomic bomb would not have been developed in 1945
without World War II, the moon landing would not have happened in
1969 without the Cold War.
The 1960's space race was a one-time miracle of political
circumstance -- a battle in the Cold War -- a repeat of which
should be neither expected nor wanted. The political will to pay
for real space advances ended just as NASA ossified. In fact, I
suspect that the former strongly led to the latter as reduction in
funding and future projects meant beaurocrats had to reorient to
protect their own turf rather than target the next leap.
Regrading the cost of the space program in Apollo days to
now-a-days, this is my favorite tidbit:
NASA spent thousands (millions?) of dollars developing a pen that
wrote in outerspace. What did the Russians do?
They used pencils.
DOH! What are the odds we've learned to be more efficient?
What did the Russians do? They used pencils.
Arguably, this urban
legend is a good example of what NASA should be doing: making
simple specifications that private interests meet at their own
expense.
They're going to take our money in taxes anyway, better a moon base amnd some asteroid habitats than a bridge to nowhere in Alaska or 5 million in aid to Chad.
This is one of those issues that's tough for libertarians.
Obviously, we'd all rather have the private sector leading the way,
without all of the bureaucratic flab that is NASA. On the other
hand, the importance of establishing a permanent manned presence in
space is quite high. And, to be frank, if the U.S. doesn't do it,
some other country will, and we absolutely cannot afford to cede
space completely to a competing nation.
I'm hopeful that private efforts in the U.S. will end up taking
over the new space race, but there's no telling for sure. If NASA
is smart, it will focus much more on figuring out a cheap method
for reaching orbit (maybe hopping on to the America's Space
Prize contest bandwagon) than on rehashing Apollo. I'm quite
impressed with the possibility of constructing a space elevator or
a space fountain, either of which would be insanely cheaper than
rockets, and NASA seems to finally be interested in these advanced
lift options. If we're lucky, the private efforts will be so
successful that NASA can be pushed aside; then the real exploration
and exploitation of space can begin in earnest.
I've already found a nice piece of land that I want to buy on Mars.
Though I plan to pay less since I've learned than the Earth will
obstruct my view of Venus.
Funding human spaceflight improves our odds of surviving as a
species. Apparently one meteoroid the size of a VW could take us
back to the stone age, or worse. No off-world colonies, no backup
plan.
Nobody ever thought the Virginia colony would amount to anything.
Boy were they wrong. Hate to say this, but it was "the vision
thing."
Somebody will eventually go to the moon -- if it's not us, it will
be the PRC. If we cede this to them, we might as well just accept
that we're a has-been civilization.
Granted, the space program, particularly as (historically)
administered by NASA is a boondoggle. At least it's supporting
scientists, engineers and people who actually *produce* something,
like miniaturized electronics. No, NASA didn't "invent" much, but
contractors working to NASA spec with NASA bucks did.
Liberal do-gooders hate the space program because it's "elitist."
Not a good reason in itself, but satisfying. They'd piss the money
away on social programs that would ultimately produce more people
needing social programs...
Pig Mannix - My guess about Griffin's prediction is "way the
hell off". The shuttle worked exactly the same way: low cost!
frequent flights! And we know how it turned out, costing way more
than predicted and flying way less than predicted. I recently did a
paper on knowledge management within NASA, and the conclusion I
came to, basically, was that NASA never changes unless it becomes
politically impossible not to change; the Moon race was
one of those times, although it was probably also helped by the
fact that NASA was fairly young.
I, like many of you, grew up with dreams of space travel, but by
now I have a different way of looking at it. Supporting NASA
because you like space exploration is like supporting the DMV
because you like cars.
Seriously, though, just build a space elevator
already.
I'm intrigued by this "airship to orbit" concept that I
stumbled across the other day. And it looks like something that can
be done at relatively low cost. (The Web site is a little hokey,
but maybe they're just spending their money where they think it's
most critical.) And safer than rockets, too.
Check out the PDF on the side. "Seven years to completion,"
folks!
And since, last I heard, H&R is only allowing one link per
post, I'll use another post to acknowledge that ...
... the "airship to orbit" concept does have its doubters:
http://en.wikipedia.org/wiki/Orbital_airship
Also, these
guys have their own take on the concept, and their "artist's
conceptions" are way, way more cool.

is part of its charm.)
FUCK! I only had ONE hreffed link in
this post originally, and it still got filtered into limbo. I guess
you can't even have more than one URL in a post, hreffed or
not?
What I meant to say was:

I think there's a hell of a lot of work to do down here on Earth
before we start spending any more money on space travel.
OK I don't really think that. Frankly I'm really for spending money
on space travel, because I'm getting tired of living on the same
planet as Paul Anka and Barry Manilow.
There is no comparison between colonizing N America and setting
up a colony on the Moon. Basic necessities like air, food, and
water could be easily obtained; the colonists lifestyle was not
radically different from what they left behind.
A better analogy would be to compare it to colonizing Antarctica.
Both are extremely harsh environments that will quickly kill you if
you make a mistake or your equipment breaks down. And the main
reson for going there is scientific knowledge; there's not a lot of
wealth coming from the South Pole.
If Columbus could have used robot ships to bring spices back
from India, would he have gone in person? I think not.
From deep space, the only stuff of value is information. That can
now be obtained without going in person.
Ask me again in a thousand years, and I may have a different
opinion.
Deadhead:
There is no comparison between colonizing N America and setting up
a colony on the Moon...
That's very easy to say looking backward from the early 21st
century. I think you're overlooking how different the worldview of
the early 17th century englishman was from your own.
Basic necessities like air, food, and water could be easily
obtained; the colonists lifestyle was not radically different from
what they left behind.
Air and water, yes. Food, no. There was serious malnutrition in the
Jamestown colony the first year. And it was radically different
from what they left behind. [sfx: buzzzer]
Clueless:
If Columbus could have used robot ships to bring spices back from
India, would he have gone in person? I think not.
Your first sentence betrays a woeful lack of historical knowledge.
The bit about the spices was just a pitch to the money men;
Columbus was all about the exploration. Your second sentence is
quite amusing, although I assume unintentionally so. [sfx:
buzzzer]
Thanks you both for being on the show, and enjoy your year's
supplies of Rice-A-Roni(r)...
Tonio, you're being silly. The life skills of farming and
hunting that the colonists used back in England were all they
needed to survive in the new world. They did not need any new
technology in order to survive, just better planning -- like
finding out what winters were like.
It would be possible to send people to the Moon, or Mars, for a
brief period of time, taking all the food, water, and air they
need. But why? There's no reason to send people; send robots. If
the robots find something that makes it worthwhile to send people,
the Earth will send people.
Here's an idea for you: stick to game-show hosting, and let us
scientists and engineers figure out what to do in space.
Dedskin, I think Mark Martin and the unnecessarily combative
Tonio are closer to the truth.
We think the colonization of the Americas wasn't as challenging
colonizing space because we lack the perspective of those earlier
colonists. Just being able to feed yourself or keep yourself from
freezing in the winter wasn't something you could take for granted
(in Europe or America). The settlers required their equivalent of
"high-tech." Sailing across the Atlantic was not a cheap, everyday
thing.
There are economic gains to be made in space, and a role for human
beings. We already take weather and communication satellites for
granted; I think the next big space industry will be Earth-orbit
tourism. (If people are willing to pay for it, it's wealth.)
Next, heavy industry -- and humans will be needed for supervisory
roles, at least. (And we'll need to build places for them to live.)
For power, there's intense sunlight that doesn't turn off every 12
hours or on stormy days. For raw materials, it's cheaper to lift
what we can from the Moon's surface and bring it to Earth orbit,
than to bring it from Earth's surface. The Moon's surface is
basically pulverized silicon, aluminum, and oxygen compounds. In
some ways it's easier to mine bodies in space for metals
-- you don't have to dig up a forest full of Bambis and spotted
owls to get at it.
If you can haul one asteriod in from the Asteroid Belt, you have
supplied the world's demand for iron and nickel for many decades,
if not centuries.
Trivia: Do you know that the Earthly economy already relies upon
the Asteroid Belt as the source of at least 10%-20% of the world's
nickel? (And a lot of copper and platinum.) Two billion years ago,
an asteroid about 5-10 miles wide hit the region that is now
Sudbury Ontario and made a nice deposit. That became one of the
biggest single sources of nickel for what used to be called the
Free World.
Robots may be our scouts, but once you have an economy built up Out
There, I don't see it as being entirely run by automation. And of
course, there's the libertarian imperative -- some people will want
to put some physical space between themselves and a world where
things are a bit too over-regulated.
Having said all that, I don't think NASA should be in charge of all
this. I think private individuals like Burt Rutan, Gary Hudson,
Richard Branson and Peter Diamandis should be.
I think if the Apollo program hadn't been run as a government
project spurred by the Cold War, we would just now be making plans
to send people to the Moon. I think Apollo was a false step, made
when we didn't yet have the technology for a sustained effort. Neil
Armstrong was our Leif Ericson, but we haven't seen our Christopher
Columbus, let alone our William Penn.
Stevo Darkly,
Not to pooh pooh excessively, but, even if I were Pecos Bill, I
don't think you could hire me to lasso an asteroid and ride it to
Earth.
A comment by Burt Rutan here would be nice.
Stevo-
To be fair, building living quarters for asteroid miners will be
somewhat more expensive than building living quarters for miners on
earth.
And while roads and trucks or trains and railroad tracks to haul
metals from mines to cities aren't cheap, neither are
spacecraft.
So I'm not holding my breath for asteroid mining.
Then again, I do concede that in some future day the costs could
change considerably. I think space tourism is on the verge of
viability, and will spurn the developments that might some day lead
to asteroid mining.
So I have big hopes but I'm not ready to invest yet.
thoreau, conceded, but I think it's inevitable that costs of
mining on Earth (including environmental preservation costs) will
get relatively higher and the costs of getting people into space,
and keeping them alive there, will become relatively less
expensive. At some point, the balance will shift, and someone will
decide it's less expensive to start mining the Moon or asteroids
than the Earth.
Ruthless: A comment by Burt Rutan here would be
nice.
Perhaps significantly, I couldn't find a statement by Rutan where
he explicitly buys into a grand vision of human being settling the
Solar System beyond the Moon.
He is focused right now on getting people affordably into Earth
orbit, and on space tourism. He does think it will become
accessible to thousands of ordinary people a year -- one of his
slogans is "space for the rest of us."
And note! Devising an affordable way to get from Earth's surface to
Earth orbit isn't just the first small step. It's the first
great big step. Once you achieve that, you're very close
to opening up the entire Solar System to colonization.
Jerry Pournelle tells a story about a conversation that a younger
SF writer (it might have been Pournelle himself) once had with
Robert Heinlein. The younger writer was struggling with an idea for
an SF story. For the plot to work, he needed a ship that could
readily get from Earth's surface to Earth orbit, but not go so far
as the Moon. The writer saw he had a plausibility problem. "After
all," he said, "once you get to Earth orbit, you're halfway to the
Moon."
"No," said Heinlein, "You're halfway to anywhere."
The younger did the math and saw that "Heinlein was very nearly
right." The energy (or more precisely, the delta vee) you need to
get from Earth surface to orbit is about the same as you need to
get from Earth orbit to orbit around nearly any other body in the
Solar System.
Unfortunately, if you go in a slow but minimum-energy manner, you
have the problem of keeping people alive during the trip -- not a
minor obstacle.
But it's very interesting to read the book Project Orion
about a "nuclear pulse" spacecraft that was proposed in the 1960s.
Basically, the thing would have pushed itself along by throwing
nuclear bombs out its tailpipe and letting the epanding explosion
hit a giant shock-abosrber plate. The book is a very interesting
read about the project's possibilities and problems. Tecnically, a
single Orion could have let us haul a big colony to Mars, all in
one piece, in a matter of weeks -- except it was totally
unsuitable, for safety reasons, for launching from Earth's surface.
Primarily for bystanders. You don't want a bunch of nukes exploding
in the atmosphere. You don't want to explain that it would raise
global risks of cancer even a very tiny fraction of a percent. And
if one bomb failed to go off after being ejected while the craft
was still climbing to orbital velocity, that would be, um,
problematic.
If Orion could be built in and launched from Earth orbit, however
-- or to be extra safe, built and launched from the Moon -- it
could be the Conestoga wagon of the Space Age.
Anyway, even Rutan believes people will routinely fly at least as
far as the Moon, and soon. I found this quote (but lost the
URL):
"The goal is affordable travel above low earth orbit. In other
words," he [Rutan] explains, "affordable travel for us to go to the
moon. Affordable travel. That means not just NASA astronauts, but
thousands of people being able to go to the moon."
In the longer term, Rutan hints at being a technological optimist,
when he says: "I have often said that confidence in nonsense is a
requirement for creativity."
Admittedly, you can go too far with that. But if humans do settle
other worlds, it'll be done by people who believe we can, not by
people who believe we can't.
Stevo D,
There may emerge a good economic reason for humans to head for
space. I'm thinking mining is too prosaic.
More likely would be rumors of a Fountain of Youth or something
like that up there.
Dedskin and Ruthless: I apologize for the unwarranted and
childish personal attack in my 9/25 post. I also apologize to
everyone for lowering the level of discourse on H&R.
Sorry.
Stevo: Thanks for pointing this out in a gentle and constructive
manner.
Dedskin: You certainly deserved to get in a shot at me. For the
record: I am a real scientist, though not in an aerospace-related
field.
Tonio,
Apology accepted, and by the way you're one of the few bloggers
I've ever seen who've done that; shows integrity.
Stevo D and others,
I think you're forgetting that in Apollo the Moon travellers had to
throw away 98 percent of their ship to get there. Contrarily ocean
sailing had been around for over two hundred years, and these ships
could carry months' worths of provisions and a storehouse of
tools.
I'm not saying humans won't venture into and colonize space
someday, I just don't see any reason, for now, to spend billions to
go to the Moon, or Mars, or the Asteroid belt. Send robots. Then if
they find something worth sending humans to develop, it will get
done.
