Nostalgia for the Future: NASA'S Bid for a Space Industry Brad Linaweaver and Avery Davis PAGE 1 Like some marble statue, Columbia gleamed white in the sun. Only part of it could be seen from the press site, the rest obscured by the protecting gantry, but it was enough to draw breath from a journalist or two on first sighting its purity of aesthetic expression. Surely such a spacecraft must be a work of art - promising to fly as high as the dreams that gave it birth. Waiting for blast-off! How that phrase resonates down the corridors of this century. The amazement lies not so much in yesterday's science fiction being today's engineering, as in the transition occurring in the waking memory of so many. Multitudes of doubters have been confronted with history rushing to keep up with the once maligned sf. If there is a music of the spheres, then perhaps also there is an irony operating on as high a plane. Blast-off is a term peculiarly applicable to the Space Shuttle. Lift-off is how we should refer to the Apollo missions, those remarkable moon crafts riding into space on the sturdy backs of von Braun's brute Saturn V's, whole towers of metal creeping up the sky with a ponderous majesty. The Space Shuttle is a different breed of spacecraft, for reasons to be enumerated in this article. But for starters, Columbia was made to go up fast. How out of character for this paragon of speed to be delayed on the pad the morning of the first launch attempt, Friday, April 10. If only nine days earlier, no one could have resisted making the obvious joke. Since the actual delay had to do with the fifth computer (the back-up computer) being out of phase with the other four, maybe this difficulty with the software was a glitch thrown into the proceedings by an April Fool's Month. One million people came to see the maiden flight of the Space Shuttle. The resultant traffic jam proved more than the local authorities had anticipated. Once off the congested roads, the basic resourcefulness of people came to the fore. They had come prepared to camp the night. All up and down the shore of the Banana River were cars, trailers, trucks, tents, and photographic equipment aplenty. The latter were lined up as mute witnesses to the important event that was soon to follow. The NASA grounds were full of vehicles with car passes. Press vehicles had to run this gauntlet to make it through to the splendid view - and relative elbow room - offered by the press site. "T minus nine minutes and holding." Everyone heard it repeatedly. The time of the blast-off was to have been 6:50 a.m. Along about 9:00, some of the more pessimistic photographers in the press area were packing their equipment. The optimists waited. At 10:20 the launch was scrubbed. They would have to start a new cycle. The next launch window was Sunday morning. If NASA is the marriage of science and engineering, then it is also public relations and sophisticated advertising. A million groans were not ignored, but the safety of the astronauts and success of the mission had to be paramount. If humanly possible, NASA would try again that weekend. A million would-be space cadets made ready to try again as well. We returned to the press site at midnight on Saturday, a few hours ahead of the traf' tic piling up again. We almost hadn't made it through the first time, though waving our press credentials at every opportunity gave us an edge. With a second chance, we weren't going to take any undue risk. Besides, this was no time for sleeping (although a few hours could be grabbed as need be). Better to stand at the edge of Mosquito Lake, anticipating how the sound would be amplified over the water on a Palm Sunday morning. After the launch we would learn that both our hearts had sped up at the moment of ignition, as though the excitement of astronaut Robert Crippen (on his first flight, with a heart rate around 130) had reached out and touched us. The old hand, John Young, had a rate around 90. But Young's excitement would display itself upon exiting the ship after touchdown, as he happily punched the air and acted as though he couldn't wait to take the ride again. Such celebrations lay in the future, as we waited for the clock to reach 7:00 a.m. on April 12, 1981. NASA had used its time well to make the computers behave during the re-cycle. "The show must go on" applies to the technician as readily as to the actor. When the countdown made it past "T minus nine minutes," a cheer arose from the viewing area. At T minus five minutes, there was another cheer, and again at T minus two and T minus one. Then it began in earnest - closer came the number ten, to be followed by the countdown we have whispered in our childhood fancies a hundred times over. At the number of four, the voice announced there was ignition. The spectacle began. PAGE 1 PAGE 3 We watched it end back home. Reduced in size on the television screen, the coming down tn Caiifornta didn't begin to compare with the visceral impact of the going up from Florida. But then we saw the ftrst part live, and that somewhat biases our perceptons. Still, it was a spaceship taking off in the beginning, with all the connotations of old pulp covers; it was a plane coming down, The beauty was in the pin-point accuracy. If there had been a red 'X' painted on the landing strip, the Columbia would have touched it, a metaphor for the precision of the mission. At the press conference the astronauts fielded questions of a generally positive tone, even waxing poetic over the view from Columbia of the emerald seas of Earth. By and large, the press treated the Space Shuttle in an optimistic light. How often have we heard the cliche that the media only cares to report bad news? "What about all the good things?" those same plaintive voices wail, no doubt thinking of deeds performed by hordes of social workers. It is in the commonplace and the mediocre that the "good news" advocates find their examples. The lie is put to their charge by the coverage given a space shot. The good can be every bit as newsworthy as the bad, provided there is something exceptional about it. A great achievement is hard to ignore. The sound of a blast-off is loud, but not even it can drown out critics of space expeditions. Supporters of a space program (be it governmental or privately funded) sometimes grow tired of their own litany, eagerly listing the spinoffs as though they were the justification for the human race taking its next important step in the evolution of an interstellar species. Talking about the dollars and cents is essential, nonetheless. There must be reasons to go to space in the here and now if the rhetoric of, say, Proxmire is to be deflated. The good senator does more than oppose government financing for space: he jeers at the very idea of man going to space in the first place. We suggest that he reflects the anti-technology attitude. NASA is in the unenviable position of begging government favor. Many divergent interests carefully watch its accomplishments. The Air Force distributed a folder of material to the press entitled "Department of Defense Support of: Orbital Flight Test #1." Imaginative minds in the Pentagon (yes, there are some) are already considering the particle beam and laser weapons systems the Space Shuttle will enable them to develop and deploy. Meanwhile, the scientists are concerned with the knowledge they may acquire through using the shuttle for research. In the current economic climate, it is likely that science and the military will reach some sort of compromise, as they so often must. The Space Shuttle is the most economical spacecraft ever developed, but it will still cost a pretty chunk of change to use. NASA is proud of Columbia. It marks a major step forward in cost effectiveness for the agency. The orbiter maybe used about a hundred times, the boosters about ten. To have a tremendous rocket vehicle that was used only once (as in the days of Apollo) was a symbol of one-mission-at-a-time thinking. That space travel is the cheapest form of travel known was lost on the man in the street. His idea of space travel cost included the expense of breaking away from Earth's gravity well. The adventure of going to the moon was sufficient to keep public interest and support alive, however. The Space Shuttle promises a greater adventure: a Mars ship could be constructed in space, designed for use in space only (aside from the landing shuttle), and no fuel would be wasted fighting Earth's gravity. Such a trip would rekindle public interest in space overnight. But how soon will it be done? Dare we hope by the end of the century? In the meantime, there are immediate projects on the drawing board. As has been said many times before, the Space Shuffle Is the first space truck. The economic advantages are obvious: crews will be able to go into space to repair unmanned satellites in orbit. If need be, satellites could be returned to Earth for overhauls. Nearly every type of satellite will be orbited and maintained by shuttles: communications, meteorology, environmental protection, navigation, fishing, farming, mapping, oceanography, and of course surveillance. Most important of all will be hungry Solar Power Satellites that in time could solve the energy problems of the world by sending the product back via microwave or laser. What's more, such salellites could lead to a self-supporting program. The really interesting area is in what the Space Shuttle promises to science. Astronauts are scientists as well as good pilots of spaceships. NASA has looked for people, however specially trained for the task at hand, who are basically generalists, able to draw upon a wide variety of fields. With permanent space laboratories as part of a comprehensive space station program, specialized scientists without intensive astronaut training will conduct experiments in space. The same goes for the expertise required by industrial projects. And eventually come the tourists! More than instruments will ride the shuttles. A permanent station to be put in low Earth orbit will be the SOC, or Space Operations Center (Skylab need never have fallen). Its primary purpose will be scientific. In addition to carrying out experiments, this station will be a base for the construction of more ambitious structures further out in geosynchronous Earth orbit. This will be the start of permanent space habitats. (Consider what that will teach us about self-contained ecologies.) As unglamorous as Columbia might have appeared to some - jumping up, orbiting low, then coming back down like a pogo stick - the grand, mad dashes into the void will come out of a down-to-earth shuttle program. PAGE 3 PAGE 2 You saw it before you heard it. Even the most experienced journalist must be without words... at first. The flame started at the bottom, the ship began to rise, exhaust fumes welling up... all before the sound struck the chest. It was a deep thunder, not as bone-crackingly loud as a Saturn V going up in the Apollo days, but still a sound that spoke to the marrow, and reverberated in the body. The sight that accompanied that sound - the shuttle climbing the sky on a pillar of long, bright flame - made the onlooker smile in joy or gape in wonder, but the face could not remain unaffected. How it sped on its way, leaving behind the purest white contrail, as if a cloud had been turned sideways and set upon the ground. We could see the orbiter, the main tank to fuel its engine, and one of the thruster shells clearly as the ship rotated in flight until the orbiter was lost from view behind the tank, The visibIlity was excellent. Before the onlookers could believe it was gone, all that remained was the billowing white column. The contrail snaked off... we had lost sight of Columbia. Then suddenly the miracle of the craft made itself plain. Someone shouted, "There it is, off to the right!" It had gone so far, so fast, that now it was a daytime star, a dot of light that appeared to be moving down the sky, but that was only because It was so far along on its trajectory that the distance tricked the eye. "Jeezus, look at that thing go!" "Go, baby, go!" "Whooeeeeeee!" "Wow!" Cries of exclamation filled the air, as the echo of thunder died away. Then it was time to look at monitor screens, to see the boosters jettisoned, leaving the main tank and Columbia herself to escape the atmosphere. Time for more instant replays than a week's worth of football games. Time for read-outs and statistics and a hundred voices talking at once. Everyone knew it was perfect - as Young would later describe the ship: "It just performed superbly." There was a good will at that press site unadulterated by cynicism. People of such widely divergent interests had come to experience the same thing: politicians (space advocate Jerry Brown among them), popular entertainers (John Denver, Pat Boone, Nichelle Nichols, Steven Spielberg, George Lucas), science fictioneers Jack and Eva Chalker, Joe and Gay Haldeman, C,J. Cherryh, David Kyle), Air Force brass, and even a troop of cub scouts. The crews from CBS, NBC, ABC, the BBC, and Atlanta's CNN were as caught up in the event when it finally happened as the kids in the Star Wars T shirts. On television, even Dan Rather smiled. There was much to be pleased about as the Space Shuttle demonstrated for the world to see what a true aerospace vehicle means: to takeoff like a rocket, maneuver in Earth orbit like a spacecraft, and land like an airplane. First of all, as if to make up for Friday's delay. the mission worked even better than NASA had anticipated. Commander Young said that it was so nominal that it was phenomenal. This time the five guidance, navigation and control computers were in synchronlzation. The rocket engines developed more thrust than they had calculated, which means Columbia could have carried five hundred pounds more payload into orbit. This presages well for the next mission. As for the recovery of the solid rocket boosters, they floated fine and will be re-used as planned. (The remains of the external tank cascaded down within ten miles of the targeted area, which is very good indeed,) Once in orbit, the reaction control system, used for maintaining spacecraft attitude, also outdid expectations by using less propellant than had been allotted. It is the age of economy-minded space missions, or as Young said: "You don't want to run out of gas on your way to orbit." The best news concerned the tiles. After some insulating tiles fell off the OMS pods (Orbiting Maneuvering System) during the launch, worry was expressed about the tiles forming the protective layer on the belly of the craft. Without them Columbia would have become an unwanted meleorite upon re-entry, al la Bradbury's "Kaleidoscope." With 34,000 tiles to dissipate temperatures up to 2300 degrees Fahrenheit, their function to protect the orbiter's aluminum body, these silica fiber blocks offered better protection than any other material considered, The design of the Space Shuttle was especially difficult because so much of what it had to do was new, and they had to get it right the first time. Columbia was born of a new kind of approach. It used to be that rocket vehicles were made by expending prototypes, the engineers learning from smoking failures on desert sands. In the early days there was no other practical way to handle the wild fires in a rocket's tubes. The trouble was with guidance. Each subsequent launch would incorporate fixes from previous failures, this cycle to be repeated until a launch achieved complete success. The unprecendented difficulty of the Space Shuttle was the need to design a rocket vehicle that would succeed on its first flight with astronauts aboard. The shuttle was a new configuration, the orbiter with liquid fuel engines piggy-back riding on an External Tank, with two solid fuel rocket boosters strapped to the ET for extra oomph! This was the first manned flight to use any solid rockets - when they start up, they can't be turned off. The most dangerous part of the mission was probably re-entry and landing. After the tiles did their job, it was up to John Young to handle the manual part - a dead stick glide in a ninety ton plane, glowing hot underneath from the friction of re-entry. Using S turns to slow down, the last leg of the trip was an unmotorized exercise in pure flying for man and computer. No wonder Young looked so happy when he came out. He had had fun! The Columbia exhibited an excellent glide ratio (i.e., more lift and less drag). This means that the shuttle should be able to land on conveniently short runways instead of requiring the long strip they used this time. It also increases the number of contingency landing sites in event of an emergency. PAGE 2 PAGE 4 Perhaps the most intriguing project for the near future of the Space Shuttle program is the Space Telescope. It will be the most powerful ever built not because of size, but due to its location. Limited by the atmosphere through which they must peer, the largest ground based telescopes cannot see more than two billion light years. In orbit, the Space Telescope will see fourteen billion light years, photographing objects fifty times fainter. The boon to astronomy will be incalculable. It will see quasars well enough to investigate their properties. Might not such data unlock the secrets of little known energy processes? The telescope will also be used to look for planets orbiting nearby stars. Some consider that the greatest benefit will be to learn more about the age of the universe. ST will mark as great an advance for modern day astronomy as Galileo's telescope did for his time. And all this will come from an unmanned telescope, controlled from the ground, but launched into orbit and serviced by the Space Shuttle. This one is scheduled for 1983. At last mankind is getting a permanent foothold in space. As that orbiting telescope looks farther than the eye can see, the question is raised: how soon will we follow its gaze? We must never forget how diverse are the motives that will inspire the exodus from Earth: the scientist lusting after knowledge; the colonist hoping for a second chance; the military rattling its sabers against new horizons; the businessman seeking celestial profits; and finally the pilots who simply want to guide their wonderful ships to alien shores. For whatever the reasons, the human race is m'aktng the journey! -30- Brad Linaweaver has writttn previously for Fantastic ("The Competitor," July, 1980). This is his first contribution to Amazing.
