What manner of creature are we? It took 100,000 years for humans to get inches off the ground. Then, astonishingly, it took only 66 to get from Kitty Hawk to the moon. And then, still more astonishingly, we lost interest, spending the remaining 30 years of the 20th century going around in circles in low earth orbit, i.e., going nowhere.
Last July, the unmanned Lunar Prospector probe was sent to find out whether the moon contains water. It was a remarkable venture, but even more remarkable was the fact that Prospector was the first NASA spacecraft, manned or unmanned, to land on the moon since the last Apollo astronaut departed in 1972. Twenty-seven years without even a glance back.
We remember the late 15th and 16th centuries as the Age of Exploration. The second half of the 20th was at one point known as the Space Age. What happened? For the first 20 years we saw space as a testing ground, an arena for splendid, strenuous exertion. We were in a race with the Soviets for space supremacy, and mobilized for it as for war. President Kennedy committed all of our resources: men, materiel, money, and spirit. And he was bold. When he promised to land a man on the moon before the decade was out, there were only eight and a half years left. At the time, no American had even orbited the earth.
The Apollo program was a triumph. But the public quickly grew bored. The interview with the moon-bound astronauts aboard Apollo 13 was not even broadcast, for lack of an audience. It was only when the flight turned into a harrowing drama of survival that an audience assembled. By Apollo 17, it was all over. The final three moonshots were canceled for lack of interest.
Looking to reinvent itself, NASA came up with the idea of a space shuttle ferrying men and machines between earth and an orbiting space station. It was a fine idea except for one thing: There was no space station. Skylab had been launched in May 1973, then manned for 171 days. But no effort was made to keep its orbit from decaying. It fell to earth and burned. We were left with an enormously expensive shuttleto nowhere.
The shuttle has had its successesthe views of earth it brought back, the repairs to the Hubble space telescope it enabled. But it has been a dead end scientifically and deadening spiritually. There is today a palpable ennui with space. When did we last get excited? When a 77-year-old man climbed into the shuttle in November 1998 for a return flight. That was the most excitement the shuttle program had engendered in yearsthe first time in a long time that a launch and the preparations and even the preflight press conference had received live coverage. Televisions were hauled into classrooms so kids could watch.
But watch what? The fact is that we were watching John Glenn reprise a flight hed made 36 years earlier. It is as if the Wright Brothers had returned to Kitty Hawk in 1939 to skim the sand once again, and the replay was treated as some great advance in aviation.
The most disturbing part of the Glenn phenomenon was the efflorescence of space nostalgiaat a time when space exploration is still in its infancy. We have not really gone anywhere yet, and we are already looking back with sweet self-satisfaction.
The other flutter of excitement generated by the shuttle program occurred a few years earlier when Shannon Lucid received the Congressional Space Medal of Honor for a long-duration flight in low earth orbit. A sign of the times. She is surely brave and spunky, but the lavish attention her feat garnered says much about the diminished state of our space program. Endurance records are fine. But the Congressional Space Medal of Honor? It used to be given to the likes of Alan Shepard and John Glenn, who had the insane courage to park themselves atop an unstable, spanking-new, largely untested eight-story bomb not knowing whether it would blow up under them. Now we give it for spending six months in an orbiting phone booth with a couple of guys named Yuri.
What happened? Where is the national will to explore? We are stuck along some quiet historical sidetrack. The fascination today is with communication, calculation, miniaturization, all in the service of multiplying human interconnectedness. Outer space has ceded pride of place to the inner space of the Internet. In fact, spaces greatest claim on our interest and resources currently rests on the fact that satellites allow us to page each other and confirm that 9:30 meeting about the new Tostitos ad campaign.
The excitement surrounding Shannon Lucids six months of sponge baths and Russian food aboard Mir is a reflection of the quiet domesticity of this inward-turning time. Perhaps it is the exhaustion after 60 years of world war, cold and hot, stretching right up to the early 1990s. The Seinfeld era is not an era for Odyssean adventures. Now is a time for home and hearththe glowing computer screen that allows endless intercourse with our fellow humans.
Another reason for the diminishing drive for planetary exploration is, perversely, the fruits of the moon landing itselfand in particular that famous photograph of earth taken by the Apollo astronauts during the first human circumnavigation of another celestial body.
Earthrise had an important effect on human consciousness. It gave us our first view of earth as it is seen from Gods perspective: warm, safe, serene, blessed. It created a kind of preemptive nostalgia for earth, at precisely the moment when earthlings were finally acquiring the ability to leave it.
It is no surprise that Earthrise should have become such a cultural icon, particularly for the environmental Left. It offered the cosmic equivalent of the call to Come home, America issued just four years after the picture was taken.
That photo and the ethos it promotedglobal, sedentary, inward-lookingwere the metaphysical complement to the political arguments made at the time, and ever since, for turning our gaze from space back to earth. These are the familiar arguments about social priorities: Why are we spending all this money on space, when there is poverty and disease and suffering at home?
It is a maddening question because, while often offered in good faith, it entirely misses the point. Poverty and disease will always be with us. We have spent, by most estimates, some $5 trillion trying to abolish poverty in the United States alone. Government is simply not very good at solving social problems. But it can be extremely good at solving technical problems. The Manhattan Project is, of course, the classic case. As are the various technological advances forged in war, from radar to computers.
Concerted national mobilization for a specific scientific objective can have great success. This is in sharp contrast to national mobilization for social objectives, which almost invariably ends in disappointment, waste, and unintended consequences (such as the dependency and deviancy spawned by the massive welfare programs and entitlements of the sixties and the seventiesthe Lefts preferred destination for the resources supposedly squandered on space).
But more exasperating than the poor social science and the misapprehension about the real capacities of government is the tone-deafness of the earth-firsters to the wonder and glory of space, and to the unique opportunity offered this generation. How can one live at the turn of the 21st century, when the planets are for the first time within our grasp, and not be moved by the grandeur of the enterprise?
NASA administrators like to talk about science and spinoffs to justify the space program. Well, the study of bone decalcification in near-earth weightlessness is fine, but it is hardly the motor force behind President Kennedys ringing declaration, We choose to go to the Moon. That is not why we, as a people and as a species, ventured into the cosmos in the first place.
Teflon and pagers are nice, too, and perhaps effective politically in selling space. But they are hardly the point. We are going into space for the same reason George Mallory climbed Everest: Because it is there. For the adventure, for the romance, for the sheer temerity of venturing into the void.
And yet, amid the national psychic letdown that followed the moon landings and is still with us today, that kind of talk seems archaic, anachronistic. So what do we do? We radically contract our horizons. We spend three decades tumbling about in near-earth orbit. We become expert in zero-G nausea and other fascinations. And when we do venture out into the glorious void, we do it on the very cheap, to accommodate the diminished national will and the pinched national resources allocated for exploration.
The reason NASA administrator Daniel Goldin adopted the faster, better, cheaper approach is that he was forced to. He was rightly afraid that when you send a $1 billion probe loaded with experiments and hardware and it fails (as happened to the Mars Observer in 1993), you risk losing your entire congressional backingand your entire program. He had little choice but to adopt a strategy of sending cheaper but more vulnerable probes in order to lessen the stakes riding on each launch. Probes like the Mars Polar Lander.
When the Mars Polar Lander disappeared last month, the country went into a snit. The public felt let down, cheated of the exotic entertainment NASA was supposed to deliver. The press was peeved, deprived of a nice big story with lovely pictures. Jay Leno, the nations leading political indicator, was merciless. (If youre stuck for something to get NASA for Christmas, you cant go wrong with a subscription to Popular Mechanics....But theyre not giving up. NASA said today theyre gonna continue to look for other forms of intelligent life in the universe. And when they find it, theyre gonna hire him.) And Congress preened, displaying concern, pulling its chin and promising hearings on the failure of the last three Mars missions. This will be a bit of Kabuki theater in which clueless politicians, whose greatest mathematical feat is calculating last weeks fund-raising take, will pinion earnest scientists about why they could not land a go-cart on the South Pole of a body 400 million miles away on a part of the planet we had never explored.
In other words, we are in for a spell of national bellyaching and finger-pointing which will inevitably culminate in the crucifixion of a couple of NASA administrators, a few symbolic budget cuts, and a feeling of self-satisfaction all around.
The biggest scandal of the Mars exploration projects is not that a few have failed, but the way the nation has reacted to those failures. A people couched and ready, expectant and entitled, armed with a remote control yet denied Martian pictures to go with their Today show coffee, will be avenged.
Who is to blame for the Mars disasters? Not the scientists, but the people who will soon be putting them on trial.
Landing on another planet is very hard. And landing on its South Pole, terra incognita for us, is even harder. As one researcher put it, this is rocket science. Look at the history of landers on Mars, professor Howard McCurdy of American University told the Washington Post. Of twelve attempts, three have made it. The Soviets lost all six of theirs....Mars really eats spacecraft.
Something this hard requires not just technologywhich we havebut will, which we dont. And national will is expressed in funding. Since the glory days of Apollo, space exploration has progressively been starved. Today, funding for NASA is one fifth what it was in 1965, less than 0.8 percent of the federal budget.
And not only has the overall NASA budget declined, but so has the fraction allocated to both manned and unmanned exploration of the moon and the planets. The budget has been eaten by the space shuttle and the low-earth-orbit space station being built two decades late to finally provide a destination for the wandering shuttle.
Then there is what NASA calls mission to planet earth, a program devoted to studying such terrestrial concerns as ozone, land use, climate variability, and such. A nice idea. But it used to be NASAs mission to lift us above ozone and land and climate to reach for something higher. The whole idea of space exploration was to find out what is out there.
The cost of the Mars Polar Lander was $165 million. In an $8 trillion economy, that is a laughable sum. Waterworld cost more. The new Bellagio hotel in Vegas could buy eight Polar Landers with $80 million left over for a bit of gambling. To put it in terms of competing space outlays, $165 million is less than half the cost of a shuttle launch. For the price of a single shuttle mission (launch, flight time, landing, and overhead) we could have sent two Mars Polar Landers and gotten $70 million back in change.
Planetary exploration is so hamstrung financially that the Polar Landerwhich NASA last week officially declared deadsent no telemetry during its final descent onto the planet. That was to save money. Well never know what went wrong. Adding a black box, something to send simple signals to tell us what happened, would have cost $5 million. Five million! That doesnt buy one minute of air time on the Super Bowl.
The hard fact is that the kind of cheap, fast spacecraft NASA has been forced to build does reduce the loss in case of failure. But it increases the chance of failure. You cannot build in the kind of backup systems that go into the larger craft we sent exploring in the past. The Viking missions that 25 years ago touched down on Mars and gave us those extraordinary first pictures of its surface, and the Voyager spacecraft that gave us magnificent flybys of the entire solar system, typically cost 10 to 20 times more than the new faster, better, cheaper projects.
It is a travesty that the very same Congress that has squeezed funding for these programs will now be conducting the inquisition to find out why this shoestring operation could not produce another spectacular success. But we cant just blame the politicians. This is a democracy. They are responding to their constituency. Their constituency is disappointed that it received no entertainment from the Mars Polar Lander, for which the average American contributed the equivalent of half a cheese burger. If we had had the will to devote a whole cheeseburger to a Mars lander, it could have been equipped with redundant systems, and might have succeeded.
The fault, dear Brutus, is not in our stars, but in ourselves. What then to do? If we are going to save resources in acknowledgment of the diminished national will to explore, we should begin by shutting the maw that is swallowing up so much of the space budget: the shuttle and the space station. It is not as if we have nowhere to go but endlessly around earth. Recent discoveries have given us new ways and new reasons for establishing a human presence on the moon and on Mars.
Until a few years ago, it could have been argued that a moon base was impractical, and human Mars exploration even more so. But there is evidence that there may be water on the moon (in the form of ice, of course). And water, there as here, is the key to everything. It could provide both life support and fuel. Similarly, the fact that there is ice on Mars has led to a revolution in thinking about how we can travel there and back. Instead of carrying huge stores of fuel, which would make the launch vehicle enormously expensive and cumbersome, we could send unmanned spacecraft ahead. They would land on Mars and turn the water into life support and fuel. (If you split water, you get hydrogen and oxygen, precisely the gases that you need for life and for propulsion.) Astronauts could travel fairly light, arriving at a place already prepared with life-sustaining water, oxygen, and hydrogen for the flight back.
The moon and Mars are beckoning. So why are we spending so much of our resources building a tinker-toy space station? In part because, a quarter-century late, we still need something to justify the shuttle. Yet the space stations purpose has shrunk to almost nothing. No one takes seriously its claims to be a platform for real science. And the original ideahatched in the 1950sthat it would be a way station to the moon and Mars, was overtaken in the sixties when we found more efficient ways to fully escape earths gravitational well.
The space stations main purpose now appears to be ...fostering international cooperation. It became too expensive for the United States to do alone, and so we decided to share the cost and control. It provides a convenient back door for American funding of the bankrupt Russian space program. We send Russia the money to build its space station modules. This is supposed to promote friendship and keep Russian rocket scientists from moving to Baghdad.
The cost to the United States? Twenty-one billion dollars, enough to support 127 Polar Landers. Instead of squandering $21 billion on a weightless United Nations (dont we have one of these already?), we should be directing our resources at the next logical step: a moon base. It would be a magnificent platform for science, for observation of the universe, and for industry. It would also be good training for Mars. And it would begin the ultimate adventure: the colonization of other worlds.
In 1991, the Stafford Commission recommended the establishment of permanent human outposts on the moon and on Mars by the early decades of this century. Rather than frittering away billions on the space station, we should be going right now to the moonwhere weve been, where we know how to go, and where we might very well discover life-sustaining materials. And from there, on to the planets.
In the end, we will surely go. But how long will it take? Five hundred years from nowa time as distant from us as is Columbusa party of settlers on excursion to Marss South Pole will stumble across some strange wreckage, just as today we stumble across the wreckage of long-forgotten ships caught in Arctic ice. Theyll wonder what manner of creature it was that sent it. What will we have told them? That after millennia of gazing at the heavens, we took one step into the void, then turned and, for the longest time, retreated to home and hearth? Or that we retained our nerve and hunger for horizons, and embraced our destiny?
