Rocks everywhere, all carefully labelled and tracked by a full-time curator. Grad students were encouraged to discard whatever they didn’t absolutely need for the future, but Henry knew that no geologist would willingly give up a single grain of sand.

To Henry it felt like coming home, after the crush and squalor of the plane, the jangling confusion of his first jet-lagged encounter with Edinburgh.

The clean lab, where the Moon rock would be processed, was a couple of storeys up. Henry was expecting a close cousin of the Lunar Curatorial Facility back home at JSC.

Well, there was a small, cramped airlock chamber here, a couple of wooden doors, like JSC. But there were no bunny suits or hats. It was just another lab, dusty, lined with grubby-looking wooden benches. There were fume cupboards on the walls, with safety notices, but their doors were ajar. Mike said the room had mostly been used, previously, by oceanographers looking for trace elements in sea water, like osmium or helium. At least there were steel-and-glass glove boxes sitting on the antique wooden benches, cheerfully bolted in place. And there were rocks, nondescript lumps, inside each of the boxes.

There was nobody working here right now. Too early in the morning, maybe.

“…The samples here are mostly just dummies,” Mike said. “A couple of meteorites and stuff. We really wanted to learn how to handle the samples. The containers are under positive pressure. I mean, the interiors contain air at a higher pressure than outside, so if there is any breach of containment the lunar material would be blown outwards, rather than have earthly contamination blow inwards. By comparison, if we were looking at radioactive material the pressure would be negative — air would be sucked inside a box in a breach, so that radioactivity would be contained. We store the samples in ultra-dry nitrogen…”

I know, Henry thought as Mike chattered nervously on. I know.

The positive pressure made the gloves, of black rubber, stick out from the boxes like questing arms, two or three feet long. As Henry walked past, the gloves seemed to bat at his chest, blindly.

“This clean room,” said Henry mildly, “doesn’t seem too clean to me. The lab at NASA is like Fort Knox.”

Mike looked defensive. “We’re trying to establish positive pressure in the room as a whole, but we’re having some trouble.”

“Trouble?”

“It’s kind of leaky. We don’t have the funding you guys have. And—”

Henry laughed. “My friend, I couldn’t give a rat’s ass. Moon rocks are just rocks. We’ll just roll up our sleeves and scrape off the shit. What do you say? Come on, show me one of these fancy boxes NASA has paid for.”

Mike grinned, still nervous. He led Henry to a glove box.
