The Clasp in the Garden Module

Fabrice wakes before the lights come on. In the garden module of the station, there is no morning and no evening. The lamps follow a plan, and the plants follow the lamps. He floats through the hatch with a water bag in one hand and a notebook in the other.

The module is small, and it smells of leaves and warm earth. Green walls of lettuce cover the left side. Dwarf wheat grows in neat rows above the door. At the far end, three tomato plants climb their wires toward the light. They are the pride of the whole crew.

Fabrice has worked here for five months. He knows every plant by its smell. He checks the water tubes first, then the roots, then the leaves. He writes numbers in his notebook with a pencil on a string. Everything on the station must be tied to something, or it drifts away.

Around his neck hangs a thin silver chain. At the end of it is a small pendant in the shape of a seed. His daughter gave it to him on the morning of his launch. "Keep it close," she said. "Then you will always bring something green home." He has worn it every day since.

The trouble is the clasp. It is a tiny hook that was never made for a place without weight. On Earth, the chain hangs down and holds it shut. Here, the chain floats, and the hook slowly opens by itself. This has happened four times this week.

This morning it happens again. Fabrice bends over the lettuce, and he feels the chain slide away from his skin. He turns quickly. The seed pendant drifts across the module, slow and bright, straight toward the grille of the air vent. If it touches the grille, the fan will pull it in.

He pushes off the wall and flies after it. His fingers close around the chain one hand's width from the vent. The fan hums. His heart beats hard in his ears. He stays there for a moment, holding his daughter's gift, and breathing slowly.

"That was close," says a calm voice from the hatch. Sven, the station engineer, hangs in the doorway with a toolbag. He has a long grey beard that floats around his face like a small cloud. "I heard you shout. Was it the necklace again?"

"The clasp," Fabrice says. "It opens every few hours. One day I will not catch it."

Sven floats closer and looks at the chain. He turns the little hook between two fingers. "This clasp is too weak for life up here. I can fix it, but I have two ideas, and both are good."

Fabrice waits. He knows that Sven likes to explain things slowly.

"The first idea is a tiny screw clasp," Sven says. "I can print one in the workshop tonight. You close it with a small tool, and it will never open by itself. But when you want it off, you can take it off."

"And the second idea?"

"No clasp at all. I make the chain into one closed loop, just big enough to go over your head. Nothing to break. Nothing to open. But you cannot take it off without cutting it."

Fabrice laughs. "Both are good. That is the problem."

"Take your time," Sven says. "I will be in the workshop until dinner." He pushes off the doorframe and glides away.

All morning, Fabrice works and thinks. He thins the lettuce. He measures the wheat. He pollinates the tomato flowers with a small soft brush, one by one. Every time he stops, his hand goes to the pendant, to check that it is still there.

At first he likes the screw clasp. It would let him take the chain off at night, or when he works with the nutrient liquid. A loose chain near the fans can be dangerous. And on the day he flies home, he must take everything off for the long ride. A loop he cannot remove sounds like a trap.

Then the middle of the day comes, and he tries an experiment. He takes the pendant off and puts it on the shelf beside his notebook. He ties it down with a loose bit of string, like a careful person. He works for ten minutes on the tomato wires. When he turns around, the string is loose, and the seed is drifting past the lettuce.

He catches it again. He does it a second time, to be sure. The third time, he does not need to be sure. Every time he puts it down, it leaves him.

He thinks about this while he eats lunch from a silver bag. He thinks about how the clasp was never the real problem. The problem was the moment when the necklace was not touching him. On this station, nothing stays where you put it. The only things that stay are the ones you keep on your body.

In the afternoon, he finds Sven in the workshop. The room is full of small drawers and soft lamps. A printing machine hums in the corner, building something thin and white.

"I have decided," Fabrice says. "I want the closed loop."

Sven raises one grey eyebrow. "Even though you cannot take it off?"

"I do not want to take it off. That is what I learned today." Fabrice tells him about the shelf, the string and the drifting seed. "Every time I put it down, I lose it. If I never put it down, I never lose it."

"And on the day you go home?"

"Then you can cut it, and I will thank you." Fabrice smiles. "My daughter will help me choose a new chain. She will like that more than a clasp."

Sven nods slowly. He takes the necklace and holds it under a small lamp. With a tiny heat tool and a steady hand, he joins the ends of the chain. The silver glows for a second. He lets it cool in the air, then checks the join with a magnifying glass.

"It is smooth," he says. "You will never feel it." He lifts the chain and slips it gently over Fabrice's head. The pendant floats up for a moment and then settles against his chest.

Fabrice touches it. It feels the same as before, and also completely different. It feels finished.

Late that evening, the lamps in the garden module slowly dim to their night colour. Fabrice floats alone between the green walls. The lettuce leaves move gently in the soft air from the vents. Beyond the small round window, the Earth turns, blue and white, very quiet.

At the end of the module, the biggest tomato is changing colour. This morning it was green. Now one side is pale orange, like the first light before dawn. Fabrice floats beside it and watches. The silver seed rises a little on its loop. It rests against his shirt, bright in the lamplight, beside the slow green and gold.
