-
- @1 Dreaming of space-flight, and predicting its future, have
- always been favorite pastimes of science fiction. In my first science
- column for F&SF, I can't resist the urge to contribute a bit to this
- grand tradition.
- A science-fiction writer in 1991 has a profound advantage over
- the genre's pioneers. Nowadays, space-exploration has a past as
- well as a future. "The conquest of space" can be judged today, not
- just by dreams, but by a real-life track record.
- Some people sincerely believe that humanity's destiny lies in the
- stars, and that humankind evolved from the primordial slime in order
- to people the galaxy. These are interesting notions: mystical and
- powerful ideas with an almost religious appeal. They also smack a
- little of Marxist historical determinism, which is one reason why the
- Soviets found them particularly attractive.
- Americans can appreciate mystical blue-sky rhetoric as well as
- anybody, but the philosophical glamor of "storming the cosmos"
- wasn't enough to motivate an American space program all by itself.
- Instead, the Space Race was a creation of the Cold War -- its course
- was firmly set in the late '50s and early '60s. Americans went into
- space *because* the Soviets had gone into space, and because the
- Soviets were using Sputnik and Yuri Gagarin to make a case that
- their way of life was superior to capitalism.
- The Space Race was a symbolic tournament for the newfangled
- intercontinental rockets whose primary purpose (up to that point) had
- been as instruments of war. The Space Race was the harmless,
- symbolic, touch-football version of World War III. For this reason
- alone: that it did no harm, and helped avert a worse clash -- in my
- opinion, the Space Race was worth every cent. But the fact that it was
- a political competition had certain strange implications.
- Because of this political aspect, NASA's primary product was
- never actual "space exploration." Instead, NASA produced public-
- relations spectaculars. The Apollo project was the premiere example.
- The astonishing feat of landing men on the moon was a tremendous
- public-relations achievement, and it pretty much crushed the Soviet
- opposition, at least as far as "space-racing" went.
- On the other hand, like most "spectaculars," Apollo delivered
- rather little in the way of permanent achievement. There was flag-
- waving, speeches, and plaque-laying; a lot of wonderful TV coverage;
- and then the works went into mothballs. We no longer have the
- capacity to fly human beings to the moon. No one else seems
- particularly interested in repeating this feat, either; even though the
- Europeans, Indians, Chinese and Japanese all have their own space
- programs today. (Even the Arabs, Canadians, Australians and
- Indonesians have their own satellites now.)
- In 1991, NASA remains firmly in the grip of the "Apollo
- Paradigm." The assumption was (and is) that only large, spectacular
- missions with human crews aboard can secure political support for
- NASA, and deliver the necessary funding to support its eleven-billion-
- dollar-a-year bureaucracy. "No Buck Rogers, no bucks."
- The march of science -- the urge to actually find things out
- about our solar system and our universe -- has never been the driving
- force for NASA. NASA has been a very political animal; the space-
- science community has fed on its scraps.
- Unfortunately for NASA, a few historical home truths are
- catching up with the high-tech white-knights.
- First and foremost, the Space Race is over. There is no more
- need for this particular tournament in 1992, because the Soviet
- opposition is in abject ruins. The Americans won the Cold War. In
- 1992, everyone in the world knows this. And yet NASA is still running
- space-race victory laps.
- What's worse, the Space Shuttle, one of which blew up in 1986,
- is clearly a white elephant. The Shuttle is overly complex, over-
- designed, the creature of bureaucratic decision-making which tried to
- provide all things for all constituents, and ended-up with an
- unworkable monster. The Shuttle was grotesquely over-promoted,
- and it will never fulfill the outrageous promises made for it in the '70s.
- It's not and never will be a "space truck." It's rather more like a Ming
- vase.
- Space Station Freedom has very similar difficulties. It costs far
- too much, and is destroying other and more useful possibilities for
- space activity. Since the Shuttle takes up half NASA's current budget,
- the Shuttle and the Space Station together will devour most *all* of
- NASA's budget for *years to come* -- barring unlikely large-scale
- increases in funding.
- Even as a political stage-show, the Space Station is a bad bet,
- because the Space Station cannot capture the public imagination.
- Very few people are honestly excited about this prospect. The Soviets
- *already have* a space station. They've had a space station for years
- now. Nobody cares about it. It never gets headlines. It inspires not
- awe but tepid public indifference. Rumor has it that the Soviets (or
- rather, the *former* Soviets) are willing to sell their "Space Station
- Peace" to any bidder for eight hundred million dollars, about one
- fortieth of what "Space Station Freedom" will cost -- and nobody can
- be bothered to buy it!
- Manned space exploration itself has been oversold. Space-
- flight is simply not like other forms of "exploring." "Exploring"
- generally implies that you're going to venture out someplace, and
- tangle hand-to-hand with wonderful stuff you know nothing about.
- Manned space flight, on the other hand, is one of the most closely
- regimented of human activities. Most everything that is to happen on
- a manned space flight is already known far in advance. (Anything not
- predicted, not carefully calculated beforehand, is very likely to be a
- lethal catastrophe.)
- Reading the personal accounts of astronauts does not reveal
- much in the way of "adventure" as that idea has been generally
- understood. On the contrary, the historical and personal record
- reveals that astronauts are highly trained technicians whose primary
- motivation is not to "boldly go where no one has gone before," but
- rather to do *exactly what is necessary* and above all *not to mess up
- the hardware.*
- Astronauts are not like Lewis and Clark. Astronauts are the
- tiny peak of a vast human pyramid of earth-bound technicians and
- mission micro-managers. They are kept on a very tight
- (*necessarily* tight) electronic leash by Ground Control. And they
- are separated from the environments they explore by a thick chrysalis
- of space-suits and space vehicles. They don't tackle the challenges of
- alien environments, hand-to-hand -- instead, they mostly tackle the
- challenges of their own complex and expensive life-support
- machinery.
- The years of manned space-flight have provided us with the
- interesting discovery that life in free-fall is not very good for people.
- People in free-fall lose calcium from their bones -- about half a percent
- of it per month. Having calcium leach out of one's bones is the same
- grim phenomenon that causes osteoporosis in the elderly --
- "dowager's hump." It makes one's bones brittle. No one knows quite
- how bad this syndrome can get, since no one has been in orbit much
- longer than a year; but after a year, the loss of calcium shows no
- particular sign of slowing down. The human heart shrinks in free-
- fall, along with a general loss of muscle tone and muscle mass. This
- loss of muscle, over a period of months in orbit, causes astronauts and
- cosmonauts to feel generally run-down and feeble.
- There are other syndromes as well. Lack of gravity causes
- blood to pool in the head and upper chest, producing the pumpkin-
- faced look familiar from Shuttle videos. Eventually, the body reacts
- to this congestion by reducing the volume of blood. The long-term
- effects of this are poorly understood. About this time, red blood cell
- production falls off in the bone marrow. Those red blood cells which
- are produced in free-fall tend to be interestingly malformed.
- And then, of course, there's the radiation hazard. No one in
- space has been severely nuked yet, but if a solar flare caught a crew in
- deep space, the results could be lethal.
- These are not insurmountable medical challenges, but they
- *are* real problems in real-life space experience. Actually, it's rather
- surprising that an organism that evolved for billions of years in
- gravity can survive *at all* in free-fall. It's a tribute to human
- strength and plasticity that we can survive and thrive for quite a
- while without any gravity. However, we now know what it would be
- like to settle in space for long periods. It's neither easy nor pleasant.
- And yet, NASA is still committed to putting people in space.
- They're not quite sure why people should go there, nor what people
- will do in space once they're there, but they are bound and determined
- to do this despite all obstacles.
- If there were big money to be made from settling people in
- space, that would be a different prospect. A commercial career in
- free-fall would probably be safer, happier, and more rewarding than,
- say, bomb-disposal, or test-pilot work, or maybe even coal-mining.
- But the only real moneymaker in space commerce (to date, at least) is
- the communications satellite industry. The comsat industry wants
- nothing to do with people in orbit.
- Consider this: it costs $200 million to make one shuttle flight.
- For $200 million you can start your own communications satellite
- business, just like GE, AT&T, GTE and Hughes Aircraft. You can join
- the global Intelsat consortium and make a hefty 14% regulated profit
- in the telecommunications business, year after year. You can do quite
- well by "space commerce," thank you very much, and thousands of
- people thrive today by commercializing space. But the Space Shuttle,
- with humans aboard, costs $30 million a day! There's nothing you can
- make or do on the Shuttle that will remotely repay that investment.
- After years of Shuttle flights, there is still not one single serious
- commercial industry anywhere whose business it is to rent workspace
- or make products or services on the Shuttle.
- The era of manned spectaculars is visibly dying by inches. It's
- interesting to note that a quarter of the top and middle management
- of NASA, the heroes of Apollo and its stalwarts of tradition, are
- currently eligible for retirement. By the turn of the century, more than
- three-quarters of the old guard will be gone.
- This grim and rather cynical recital may seem a dismal prospect
- for space enthusiasts, but the situation's not actually all that dismal at
- all. In the meantime, unmanned space development has quietly
- continued apace. It's a little known fact that America's *military*
- space budget today is *twice the size* of NASA's entire budget! This
- is the poorly publicized, hush-hush, national security budget for
- militarily vital technologies like America's "national technical means
- of verification," i.e. spy satellites. And then there are military
- navigational aids like Navstar, a relatively obscure but very
- impressive national asset. The much-promoted Strategic Defence
- Initiative is a Cold War boondoggle, and SDI is almost surely not long
- for this world, in either budgets or rhetoric -- but both Navstar and
- spy satellites have very promising futures, in and/or out of the
- military. They promise and deliver solid and useful achievements,
- and are in no danger of being abandoned.
- And communications satellites have come a very long way since
- Telstar; the Intelsat 6 model, for instance, can carry thirty thousand
- simultaneous phone calls plus three channels of cable television.
- There is enormous room for technical improvement in comsat
- technologies; they have a well-established market, much pent-up
- demand, and are likely to improve drastically in the future. (The
- satellite launch business is no longer a superpower monopoly; comsats
- are being launched by Chinese and Europeans. Newly independent
- Kazakhstan, home of the Soviet launching facilities at Baikonur, is
- anxious to enter the business.)
- Weather satellites have proven vital to public safety and
- commercial prosperity. NASA or no NASA, money will be found to
- keep weather satellites in orbit and improve them technically -- not
- for reasons of national prestige or flag-waving status, but because it
- makes a lot of common sense and it really pays.
- But a look at the budget decisions for 1992 shows that the
- Apollo Paradigm still rules at NASA. NASA is still utterly determined
- to put human beings in space, and actual space science gravely suffers
- for this decision. Planetary exploration, life science missions, and
- astronomical surveys (all unmanned) have been cancelled, or
- curtailed, or delayed in the1992 budget. All this, in the hope of
- continuing the big-ticket manned 50-billion-dollar Space Shuttle, and
- of building the manned 30-billion-dollar Space Station Freedom.
- The dire list of NASA's sacrifices for 1992 includes an asteroid
- probe; an advanced x-ray astronomy facility; a space infrared
- telescope; and an orbital unmanned solar laboratory. We would have
- learned a very great deal from these projects (assuming that they
- would have actually worked). The Shuttle and the Station, in stark
- contrast, will show us very little that we haven't already seen.
- There is nothing inevitable about these decisions, about this
- strategy. With imagination, with a change of emphasis, the
- exploration of space could take a very different course.
- In 1951, when writing his seminal non-fiction work THE
- EXPLORATION OF SPACE, Arthur C. Clarke created a fine
- imaginative scenario of unmanned spaceflight.
- "Let us imagine that such a vehicle is circling Mars," Clarke
- speculated. "Under the guidance of a tiny yet extremely complex
- electronic brain, the missile is now surveying the planet at close
- quarters. A camera is photographing the landscape below, and the
- resulting pictures are being transmitted to the distant Earth along a
- narrow radio beam. It is unlikely that true television will be possible,
- with an apparatus as small as this, over such ranges. The best that
- could be expected is that still pictures could be transmitted at intervals
- of a few minutes, which would be quite adequate for most purposes."
- This is probably as close as a science fiction writer can come to
- true prescience. It's astonishingly close to the true-life facts of the
- early Mars probes. Mr. Clarke well understood the principles and
- possibilities of interplanetary rocketry, but like the rest of mankind in
- 1951, he somewhat underestimated the long-term potentials of that
- "tiny but extremely complex electronic brain" -- as well as that of
- "true television." In the 1990s, the technologies of rocketry have
- effectively stalled; but the technologies of "electronic brains" and
- electronic media are exploding exponentially.
- Advances in computers and communications now make it
- possible to speculate on the future of "space exploration" along
- entirely novel lines. Let us now imagine that Mars is under thorough
- exploration, sometime in the first quarter of the twenty-first century.
- However, there is no "Martian colony." There are no three-stage
- rockets, no pressure-domes, no tractor-trailers, no human settlers.
- Instead, there are hundreds of insect-sized robots, every one of
- them equipped not merely with "true television," but something much
- more advanced. They are equipped for *telepresence.* A human
- operator can see what they see, hear what they hear, even guide them
- about at will (granted, of course, that there is a steep transmission
- lag). These micro-rovers, crammed with cheap microchips and laser
- photo-optics, are so exquisitely monitored that one can actually *feel*
- the Martian grit beneath their little scuttling claws. Piloting one of
- these babies down the Valles Marineris, or perhaps some unknown
- cranny of the Moon -- now *that* really feels like "exploration." If
- they were cheap enough, you could dune-buggy them.
- No one lives in space stations, in this scenario. Instead, our
- entire solar system is saturated with cheap monitoring devices. There
- are no "rockets" any more. Most of these robot surrogates weigh less
- than a kilogram. They are fired into orbit by small rail-guns mounted
- on high-flying aircraft. Or perhaps they're launched by laser-ignition:
- ground-based heat-beams that focus on small reaction-chambers and
- provide their thrust. They might even be literally shot into orbit by
- Jules Vernian "space guns" that use the intriguing, dirt-cheap
- technology of Gerald Bull's Iraqi "super-cannon." This wacky but
- promising technique would be utterly impractical for launching human
- beings, since the acceleration g-load would shatter every bone in their
- bodies; but these little machines are *tough.*
- And small robots have many other advantages. Unlike manned
- craft, robots can go into harm's way: into Jupiter's radiation belts, or
- into the shrapnel-heavy rings of Saturn, or onto the acid-bitten
- smoldering surface of Venus. They stay on their missions,
- operational, not for mere days or weeks, but for decades. They are
- extensions, not of human population, but of human senses.
- And because they are small and numerous, they should be
- cheap. The entire point of this scenario is to create a new kind of
- space-probe that is cheap, small, disposable, and numerous: as cheap
- and disposable as their parent technologies, microchips and video,
- while taking advantage of new materials like carbon-fiber, fiber-
- optics, ceramic, and artificial diamond.
- The core idea of this particular vision is "fast, cheap, and out of
- control." Instead of gigantic, costly, ultra-high-tech, one-shot efforts
- like NASA's Hubble Telescope (crippled by bad optics) or NASA's
- Galileo (currently crippled by a flaw in its communications antenna)
- these micro-rovers are cheap, and legion, and everywhere. They get
- crippled every day; but it doesn't matter much; there are hundreds
- more, and no one's life is at stake. People, even quite ordinary people,
- *rent time on them* in much the same way that you would pay for
- satellite cable-TV service. If you want to know what Neptune looks
- like today, you just call up a data center and *have a look for
- yourself.*
- This is a concept that would truly involve "the public" in space
- exploration, rather than the necessarily tiny elite of astronauts. This
- is a potential benefit that we might derive from abandoning the
- expensive practice of launching actual human bodies into space. We
- might find a useful analogy in the computer revolution: "mainframe"
- space exploration, run by a NASA elite in labcoats, is replaced by a
- "personal" space exploration run by grad students and even hobbyists.
- In this scenario, "space exploration" becomes similar to other
- digitized, computer-assisted media environments: scientific
- visualization, computer graphics, virtual reality, telepresence. The
- solar system is saturated, not by people, but by *media coverage.
- Outer space becomes *outer cyberspace.*
- Whether this scenario is "realistic" isn't clear as yet. It's just a
- science-fictional dream, a vision for the exploration of space:
- *circumsolar telepresence.* As always, much depends on
- circumstance, lucky accidents, and imponderables like political will.
- What does seem clear, however, is that NASA's own current plans are
- terribly far-fetched: they have outlived all contact with the political,
- economic, social and even technical realities of the 1990s. There is no
- longer any real point in shipping human beings into space in order to
- wave flags.
- "Exploring space" is not an "unrealistic" idea. That much, at
- least, has already been proven. The struggle now is over why and
- how and to what end. True, "exploring space" is not as "important"
- as was the life-and-death Space Race struggle for Cold War pre-
- eminence. Space science cannot realistically expect to command the
- huge sums that NASA commanded in the service of American political
- prestige. That era is simply gone; it's history now.
- However: astronomy does count. There is a very deep and
- genuine interest in these topics. An interest in the stars and planets is
- not a fluke, it's not freakish. Astronomy is the most ancient of human
- sciences. It's deeply rooted in the human psyche, has great historical
- continuity, and is spread all over the world. It has its own
- constituency, and if its plans were modest and workable, and played
- to visible strengths, they might well succeed brilliantly.
- The world doesn't actually need NASA's billions to learn about
- our solar system. Real, honest-to-goodness "space exploration"
- never got more than a fraction of NASA's budget in the first place.
- Projects of this sort would no longer be created by gigantic
- federal military-industrial bureaucracies. Micro-rover projects could
- be carried out by universities, astronomy departments, and small-
- scale research consortia. It would play from the impressive strengths
- of the thriving communications and computer tech of the nineties,
- rather than the dying, centralized, militarized, politicized rocket-tech
- of the sixties.
- The task at hand is to create a change in the climate of opinion
- about the true potentials of "space exploration." Space exploration,
- like the rest of us, grew up in the Cold War; like the rest of us, it must
- now find a new way to live. And, as history has proven, science fiction
- has a very real and influential role in space exploration. History
- shows that true space exploration is not about budgets. It's about
- vision. At its heart it has always been about vision.
- Let's create the vision.
