need it to be a fraction of a degree warmer than everything else around it.”
The display screen flickered and the ghostly blob of attenuated Polk molecules was replaced by a thermal map that was a deep blue-black. Wilson gave the thermal map his attention.
“So you’re looking for something that’s ever so slightly above absolute zero,” Schmidt said.
“Space is actually a couple of degrees above absolute zero,” Wilson said. “Particularly inside a planetary system.”
“Seems like an irrelevant detail,” Schmidt said.
“And you call yourself a scientist,” Wilson said.
“No, I don’t,” Schmidt said.
“Good thing, then,” Wilson said.
“So what happens if it has entropied out?” Schmidt said. “If it’s the same temperature as everything else around it?”
“Well, then, we’re screwed,” Wilson said.
“I don’t love your bracing honesty,” Schmidt said.
“Ha!” Wilson said, and suddenly the image in the display pitched inward, falling vertiginously toward something that was invisible until almost the last second, and was an only slightly lighter blue-black than everything around it even then.
“Is that it?” Schmidt asked.
“Let me change the false color temperature scale,” Wilson said. The object, spherical, suddenly blossomed green.
“That’s the black box,” Schmidt said.
“It’s the right size and shape,” Wilson said. “If it’s not the black box, the universe is messing with us. There are some other warmer objects out there, but they’re not the right size profile.”
“What are they?” Schmidt asked.
Wilson shrugged. “Possibly chunks of the Polk with sealed pockets of air in them. Right now, don’t know, don’t care.” He pointed at the sphere. “This is what we came for.”
Schmidt peered closely at the image. “How much warmer is it than everything around it?” he asked.
“Point zero zero three degrees Kelvin,” Wilson said. “Another hour or two and we would never have found it.”
“Don’t tell me that,” Schmidt said. “It makes me retroactively nervous.”
“Science is built on tiny variances, my friend,” Wilson said.
“So now what?” Schmidt asked.
“Now I get to tell Captain Coloma to warm up the shuttle, and you get to tell your boss that if this mission fails, it will be because of her, not us,” Wilson said.
“I think I’ll avoid putting it that way,” Schmidt said.
“That’s why you’re the diplomat,” Wilson said.
VII.
The discussion with Captain Coloma was not entirely pleasant. She demanded a rundown of the protocol used to locate the black box, which Wilson provided, quickly, his eye on the clock. Wilson suspected the captain hadn’t expected him to locate the black box within the time allotted to him and was nonplussed when he had, and was now trying to manufacture a reason not to let him at the shuttle. In the end she couldn’t manufacture one, although for security reasons, she said, she didn’t release the shuttle pilot. Wilson wondered, if something bad happened to the shuttle while it was in his possession, what good it would do to have a shuttle pilot on board the Clarke . But in this as in many things, he let it go, smiled, saluted, and then thanked the captain for her cooperation.
The shuttle was designed for transport rather than for retrieval, which meant that Wilson would have to do some improvisation. One of the improvisations would include opening the interior of the shuttle to the hard vacuum of space, which was a prospect that did not excite Wilson, for several reasons. He pored over the shuttle specifications to see whether the thing could handle such an event; the Clarke was a diplomatic rather than a military ship, which meant it and everything in it had been constructed in civilian shipyards and possibly on different plans from those of the military ships and shuttles Wilson had become used to. Fortunately, Wilson discovered, the diplomatic shuttle, while its interior was
