MISSION HEATER
Wu Fengtse had chosen to ship out in a One. That had its advantages, and its faults. The biggest advantage was that if there was nothing to land on, and the only reward would be some kind of science bonus for observations, he could keep it all himself.
It didn't happen that way, though. When he came out of FTL drive, he found himself in orbit around a more or less Earth-type planet.
So Wu had to face the problem of every single prospector: If he took his lander down to the surface of the planet, no one would be left in the ship. If anything happened to him on the surface, no one would be there to rescue him. He was completely on his own.
His other problem was that "Earth-type" was only a very approximate description of the world he had to explore. "Earth-type" meant that the planet was about the right size, and that it had an atmosphere and a temperature range that permitted water vapor in the air, liquid water in its shallow seas, and frozen water on its colder parts. It wasn't heaven, though. Its colder parts included nearly all of the planet. Its best zone was around the equator, and that was not much unlike Labrador.
If there ever had been anything on any other part of its surface, it was now covered with thousands of feet of ice. There was no point in landing on a glacier; Wu had no way of digging down to whatever lay under it. After a lot of searching Wu found a bare outcropping of rock and landed there. By then he wasn't very optimistic anymore. The environment did not look promising—but his instruments gave him better news than he had expected.
There was a tunnel.
Wu had practiced tunnel entry. He even had the necessary equipment. Sweating the big power drills into place and erecting the bubble shelter that would protect it from the outside air took all of his strength, and enough time to use up the bulk of his supplies. But he got in.
It was a blue-lined tunnel.
That was discouraging, but as he moved along it he caught glimpses of other colors. When he got to a red segment he found a huge machine—later on, experts decided from his description that it had been a tunnel digger—but he didn't have the strength to lift it, or the equipment (or the courage, for that matter) to try to hack pieces off it. In the green part of the tunnel were bolts of what Wu first took to be cloth but turned out to be the crystalline sheeting the "prayer fans" were made of. In the gold was—the gold. There were stacks and stacks of little hexagonal Heechee-metal boxes, all sealed. All heavy.
Wu couldn't carry them all, and his energy was running out. He managed to get two of them back to the lander and then took off, with every intention of coming back in a Five.
Unfortunately, when he was safely back on Gateway it turned out that no Five would accept the program that had brought him there. Neither would any of the Threes or Ones that were lying in their docks, waiting for crews.
It seemed that only the One he had found the planet in would take him back.
That didn't work, either. Before he could requisition it and ship out again someone else had taken his One—on a one-way trip.
All Wu had, then, was the two little boxes, but it was their contents that bought him a home in Shensi province. One of them contained heater coils. They weren't operating, but they were close enough to working condition so that human scientists managed to tinker them going. (Later on better and bigger ones were found on Peggy's Planet, but Wu's were still the first.) The other box contained a set of gauges for measuring microwave flux.
Scientists puzzled over the gauges very diligently, but they asked the wrong questions. What they labored to ascertain was how they worked. It did not occur to any of them, just then, to wonder why the Heechee were so curious about millimeter microwave flux. If it had it might have saved a lot of people a lot of unnecessary confusion.
It was in a tunnel on an otherwise unprepossessing planet that one prospector found the first specimen of the Heechee tunneling machine. It was in a tunnel on the Luna-like satellite of a distant gas giant planet that another found the "camera" that the so-called "fire-pearls" served as "film." And it was in a tunnel that Vitaly Klemenkov found the little device that sparked a whole new industry—and earned him only a pittance.
Klemenkov's is a kind of hard-luck story. What he found was what human scientists came to call a "piezo-phone." Its main operating part was a diaphragm made out of the same material as the "blood-diamonds" that had littered the tunnel of Venus and many others. The material was piezoelectric: when squeezed it produced an electric current, and vice versa. Of course, there were plenty of blood-diamonds around, though no one had known before Klemenkov that they were basically raw material for piezoelectric devices. Klemenkov had visions of untold riches. Unfortunately, the main communications laboratories on Earth, subsidiaries of the cable and telephone and satellite corporations, developed the Heechee model into something they could manufacture themselves. Klemenkov took it to court, naturally—but who could fight the lawyers of the biggest corporations in the world? So he settled for a small royalty—hardly more, in fact, than an average emperor's income.
There was one other splendidly productive variety of place to find Heechee treasures. But no one knew that at first, although if they had thought of the example of Gateway itself they might have deduced it, and certainly no one knew that these rich lodes were, actually, traps. A woman named Patricia Bover was the first Gateway prospector to report finding one—and, as was so often the case, it did her little good.
