In Defense of Human Spaceflight

“And from the crew of Apollo 8, we close, with good night, good luck, a Merry Christmas, and God bless all of you, all of you on the good earth.” Frank Boreman Apollo 8 “Robotic exploration is to real exploration as masturbation is to glorious, loving sex.”- Anonymous Nothing is more irrelevant than the supposition, even if true, that robots can carry out space exploration better than humans can. The exploration of space is not only a matter of thrust ratios, frequencies and angstroms; it is a matter both of our survival and of our spiritual and moral growth as a species. Are we merely dust that through some accident of cosmic proportions has become aware of itself? Are we the only life in all the long, lonely, light-years? Or are we travelers in time and space on a journey searching for “The Meaning of it All?” That search proceeds outward in every direction every day. Down into the microbe and the most basic bits of life, outward into the heavens at the limits of visual, X-ray and radio telescopes. In the quiet moments when we contemplate the universe in our individual lives, whether in a monk’s meditation at a monastery, a child’s prayer or the appreciation of some wild and untouched place. This is the distinction between us and our machines. The plucky rovers on Mars are not plucky- that is anthropomorphism. Nor are they exhilarated by the awe and mystery that reaches from, “the inner mind to the Outer Limits.” They will never call back from Mars saying, “Mars is so cool!” and refer to anything more than the temperature. They are not self-aware. They have no possibility of an existence after this, no chance that they could ever be more than they are at this moment.
Can’t we get our thrills secondhand? No. A camera is not an eye and a rover is not a person. Does anyone believe that Sojourner on Mars had the impact of Neil Armstrong’s “One small step for man?” on our moon? We go to the ocean depths, the clouds and the vacuum beyond, not merely for commerce, not only to fight our battles, but to gain new perspectives on our condition, and ourselves new measurements for our awareness. To anyone who has seen the Mona Lisa in person, seeing it on TV or in an art book is meaningless. The original cannot be captured, it must be experienced.


Perhaps a better example came from my own experience.  My wife and I were walking at the wonderful Asheville zoo.  We were on a stairway; unbeknownst to us we were just outside the lion’s exhibit.  A lion roared.  I’ve heard the MGM lion do it at movies for years.  But this wasn’t a recording.  It was a real lion at point blank range and it bypassed our conscious minds to hit our hindbrains first.  My wife flew up the stairs in a blur.  Black belt that I am, I snapped around in a fighting stance faster than ever before.  A classic example of fight-flight reflexes, for all that my only chance against the lion would have been to choke it to death by stuffing myself down its gullet.  You can watch “Animal Planet” until hell freezes over and it will not for one instant, approximate the reality of what is like to hear a lion roar in person.

There are of course the usual arguments against humans in space.  But let’s start with an examination of that statement, “humans in space.”  Humanity is now and has always been “in space.”  The thing in the sky is a G-2 main sequence star perhaps halfway through its lifespan.  Its attributes govern every second of our existence on this ball of rock we live on.  We are in space every moment of our life.  The so-called “realists” who think of space as something outré, that doesn’t involve them, suffer from myopia of epic proportions, like an astronomer who looks through the wrong end of a telescope.

Space has and can intrude on even their parochial world in an instant.  October 29, 2003 - the Halloween Storm - spawned auroras that were seen over most of North America.  Extensive satellite problems were reported, including the loss of the $450 million Midori-2 research satellite.  A huge solar storm impacted the Earth, just 19 hours after leaving the sun.  Days later on November 4, 2003, one of the most powerful X-ray flares ever detected swamped the sensors of dozens of satellites, causing satellite operations anomalies.  Astronauts hid as deep as they could go in the International Space Station, but still reported radiation effects including ocular “shooting stars.”

Meteor Crater lies thirty-five miles from Flagstaff, Arizona.  It dates from an impact 50,000 years ago.  We were here.  We just weren’t under that one as humans hadn't reached North America.  Which is good, as this was a 2.5 megaton wake-up call.  That was utterly dwarfed by the 1908 event in Tunguska, Siberia.  That event, thought to be an airburst of a bit of cosmic flotsam, was in the 10-15 megaton range, right up there with a strategic-level hydrogen fusion bomb.  These cosmic marbles aren’t gone and there is nothing that says Earth’s orbit is sacrosanct from them just because we have cell phones, cable TV and it would be gosh darn inconvenient for us to stop a thirty-five mile long rock at 45,000 mph. 

Mars is due to get one of those later this year.  It will come in over one of the Mars rovers, who will not note it with anything other than detached mechanical efficiency, if their limited instrument packages allow them to take any note at all.  We will get to see it on TV, but there, my friends, for the grace of God, go we.

I remember looking up at comet Hale-Bopp during its last approach to Earth.  While others were enjoying the cosmic light show (and I won’t claim to be immune to that) I did realize that I was looking at global species extinction mere light-minutes away, had the orbit been a little different.  A miss is as good as a mile with cosmic bowling but you are playing for all the marbles.  When you look at the moon, realize that you are looking at a body created because something hit the good earth we’re standing on, hard enough to tear that bit off and hurl it into the sky.  If that is too big for you, too out there and distant for your contemplation, go stand by Upheaval dome in Utah. 

But a mere chunk of rock is survivable.  It’s not likely to get all of us.  Though it could.  Even if it didn’t wipe us all out, would a technic civilization ever arise again?  We’ve mined most of the easily reachable resources around.  Could we start over again?

There are greater terrors in space that could whiff out our planet like a child blows out a candle on a birthday cake.  We can protect ourselves and our genetic heritage from some of them.  Asteroids might be pushed or blasted away from us but if a gamma ray burst goes off in our local area of space, well, game over.  Even basic levels of local space control will entail investment in infrastructure in space that dwarf all we have done to date.  We will need stations and not merely something like the International Space Station, but true factories, colonial stations and deep-space ships.  This can’t be thrown together from nothing, despite what Bruce Willis’ did in “Armageddon.”



Some of the “robot-firsters” will decry manned space, their advocacy exceeding that of Asimov’s Susan Calvin, “It’s too expensive.” They will be joined by the social engineers, “We need all the money to solve our problems down here on Earth.” 

Disabuse yourself of the notion that if all Earth’s miniscule space budgets were plowed into the social budgets of countries, that there would be a measurable decrease in the world’s problems.  Trillions have been poured into anti-poverty programs.  Whether this has been effective or not is a discussion for another place- however one must notice that poverty, ignorance and warfare are doing quite well.  If they were a stock they might have gone up like you hope your 401K would.  In any event, the world’s space budget is a mere rounding error on social spending.

Even more fundamentally, the two issues are unrelated.  Space is a technological battle with a social component.  Poverty is a political and social problem and far less a scientific one.  It is related to the nature of our species and its existence.  Or as my Dad put it in the most basic terms, “ If at the beginning of time you gave everyone in the world a refrigerator, at the end of the first month there would be those with a thousand refrigerators and those with none.”  And so it will always be.

Space is not simply a hole into which money that could be better used for food stamps or worker retraining is flushed.  It fundamentally helps economies and the poor.  The single most powerful example of this is the weather satellite.  Storms that sank ships and destroyed cities are now spotted early enough for avoidance and evacuation.  Farmers have the ability to plan for weather and crop management in a way their ancestors could not have dreamed of. 

Communication satellites make the world one huge party line.  The president of the United States and the premier of China can speak in real-time.  A doctor in New York City can diagnose and help treat an appendectomy in Antarctica.  On a more basic level, electronics have become so reliable they are almost taken for granted.  We have computer chips, solar cells, biomedical sensors, cell phones, blackberrys and laptops from the space program’s drive for technology.

Other may piously intone that we should not go out in to space until we get our act together as a species.  The idea that we must somehow correct all of Earth’s ills or somehow evolve to a pure state of political organization is naiveté.  Or if it is not, it may well be that in exploring space we will gain the perspectives needed to allow change to come.  Perhaps we will truly come to see Spaceship Earth as the small fragile place it is, with no safe place to leave our hazardous junk and no crew who are unimportant.  Earthrise on the moon made a seachange in how we see ourselves and our little blue marble.  The rise of the world-wide ecological movement has some root in the arid soil of the moon.

But there is no sign on the cosmic rollercoaster that says you must be this tall and morally evolved to take this ride.  I do not see our species changing that much as we head to the stars.  We are man most mortal and doomed to die (for all we are putting it off as far as we can each generation).  We will lie, pollute and corruptly make our way among the stars.  And why not?  We were not made as angels and we will not become angels anytime soon.  We were not required to be angels when we left the cave, when we left Africa, when we walked the land bridge into America and when we sailed from Europe.  The sanctimonious, who set themselves over the rest of us in judgment, will probably never find us fit enough for the stars.  Had it been left to them we’d still be in caves. 

Our machines are our tools and servants, good ones too.  We will take them with us and occasionally send them ahead for there will be hells in the galaxy that no mother’s child should face.  We will leave some of those to our mechanical friends.  But if our footprints do not overtake their tires and tracks, if we do not confront God’s handiwork and wrest from it the “meaning of it all” then we might have as well stayed home with our Xbox, playing HALO and watching Lucas and Spielberg’s more interesting pictures of space.  Or perhaps in the anteroom to Hell we will meet the dinosaurs-they will look at us and say with sympathy born of a mutual fate.  “Asteroid?  Bummer.  So you didn’t have a space program either?”
