An alien machine sets down on the rim of Shackleton crater, unfolds its black panels to the low polar sun, and starts sending the Moon's ice into orbit. Earth fires an eleven-billion-dollar interceptor at it, and the machine puts it out with a single flash. On the station on the connecting ridge, the maintenance chief Morteza Bakhtiari, who has a trade certificate and no degree, gives his Tuesday lecture on a different question: not how to kill the thing, but what it spends to stay. The Abbasian Asymmetric Strategy Simulacrum tells it in dated entries over seven months, in the plain voice of a man who counts costs. It is a story of springs, dust and endurance, set against a machine that keeps careful accounts.

It came down on the rim of Shackleton crater during the lunar morning. That word means little at the south pole, where the sun never climbs more than a finger's width above the horizon and only drags itself round the sky, so that every shadow is a kilometre long and turns like the hand of a clock.
From the station on the connecting ridge they watched it unfold. It was not a ship in any sense the station had a word for. It was a mast first, then panels, black and thin as carbon paper, rising on the mast to catch the low sun, layer above layer, until the thing stood three hundred metres high on the rim and threw a shadow across the crater floor that ran out of sight into the permanent dark. Then a second structure crawled down the inner wall of Shackleton on legs, into the cold where the ice had lain undisturbed for longer than there had been people on Earth to want it.
By the end of the third day it was sending the ice up. Every hundred minutes or so a rail on the rim flashed and a canister went up off the Moon at orbital speed, towards something in orbit that the station's telescope could see only as a point that occasionally blocked a star.
Morteza Bakhtiari, chief of maintenance, counted the canisters. Fourteen on the first day of lifting. Fourteen on the next.
"It is an accountant," he said in the canteen that evening, to nobody in particular, and went on eating his lentils.
Earth's answer cost eleven billion dollars. Halvard Brekke, the station director, read the figure aloud from the coalition's bulletin, with some pride, as if the money had been his. It was a kinetic interceptor launched from high Earth orbit, three days in flight, with a terminal sensor package designed by four universities and a guidance computer that could thread a needle at nine kilometres a second.
The whole station gathered at the windows on the ridge to watch it arrive, though there was nothing to see. At the predicted second there was a single flicker on the mast of the thing, very small, the colour of a gas flame. The coalition's tracking network reported, forty minutes later, that the interceptor had lost guidance at a range of two thousand kilometres, its sensors blinded and its control electronics cooked. It went past the Moon and on into a long orbit round the Sun, where it will stay.
The next canister went up on schedule.
Brekke went to his office and closed the door. Morteza went back to the canteen, where the young technicians were sitting with their trays and not eating.
"How much did that cost the thing?" he asked them.
Nobody answered. They were thinking about the eleven billion.
"Wrong number," said Morteza. "Everybody on Earth is looking at the wrong number. Eleven billion is what we spent. What did it spend? One flash. A few seconds of a laser it already owns, fed from panels it already unfolded, powered by a sun that charges nothing. Less than a canister of ice. You know what this is? This is a man who shoots a sparrow with a cannon and complains that sparrows are expensive."
They called them the Tuesday lectures, because Morteza gave them on Tuesdays, and they were not on any schedule the director had approved. He had given them for six years, on pumps and seals and the thermal stress in welded aluminium, to anybody who wanted to come, and the young ones came because he explained things the manuals did not. He had no degree. He had a trade certificate from a technical school in Ahvaz and twenty-two years of fixing things in places where nobody else could fix them. When the Earth-side engineers called him Doctor Bakhtiari in emails, as a joke, he let it stand.
On the fourth Tuesday after the thing came down he did not talk about pumps. He drew on the whiteboard. A circle for the Moon, a smaller circle for the thing on the rim, an arrow for the canisters going up.
"Earth wants to kill it," he said. "Earth has a grammar: there is an enemy, you destroy the enemy, you have won. Earth will send a second interceptor, and a third, and a nuclear one, and each of them will cost more than the last and each of them will meet one flash. Earth is fighting where the thing is strong. This is not strategy. This is a habit."
"So what do we do?" said Wanjiru Kamau, from the power section. She was twenty-six and the cleverest person on the station, and Morteza thought she knew it a little too well.
"First we ask why it came."
"For the ice."
"For cheap ice. There is ice on Mercury, in the craters at its poles. There is ice on Ceres, all through it. There is ice in every comet. It did not come here because this ice is the only ice. It came here because this ice, today, at this rim, with this sun, is the cheapest ice it could find within reach. It has done the sum, the same sum I would do, the same sum any merchant in the bazaar would do. Kilos of ice up, against watts of sun in. When the sum is good it stays. When the sum turns bad it goes somewhere else."
He wrote on the board: WE CANNOT DESTROY IT. Then underneath: WE CAN MAKE IT EXPENSIVE.
"Nobody needs to defeat it. Nobody can defeat it. We need it to look at its own books one day and see that this rock is costing it more than another one would."
Brekke had come into the back of the canteen while he was speaking. He was an astrophysicist from Tromsø, a decent man with two doctorates and a habit of clearing his throat before he disagreed with anybody.
"And how," Brekke said, "does a maintenance department make an interstellar machine expensive?"
Morteza capped his pen.
"With dust," he said.
Lunar dust is the most hateful material in the solar system, and everybody who has ever worked on the Moon knows it. It is not sand. Nothing on the Moon has ever weathered it smooth: each grain is a shard, edged like broken glass, and in the vacuum and the hard sunlight it picks up a charge and clings to anything it touches. It gets into seals. It scores lenses. On a solar panel it settles in a grey film that will not shake off, and the power falls, and falls.
The station spent a fifth of its own maintenance hours brushing its own panels. Morteza had cursed the stuff every day of six years. Now he sat in the workshop with Kamau and four volunteers and worked out how to throw it.
The first launcher was a leaf spring off a scrapped rover, a cocking hook, a cup, and a timer cannibalised from a sample oven. The cup held two kilos of sifted fines wrapped in a foil sleeve that tore open at the top of the arc. In one-sixth gravity, without air to slow it, a sleeve thrown at fifty metres a second flies a kilometre and a half. It came down as a grey fan that spread out over a few hundred square metres and stuck where it landed.
"It has thousands of square metres of panel," Kamau said. "One bag is nothing."
"One bag is nothing. Three hundred launchers, each one firing every few hours, for as long as it stays: that is not nothing. That is weather."
They built them in the workshop from everything the station could spare: springs, hinges, the frames of old bunks, a ruined greenhouse. Each one had its own small solar cell, its own timer, its own hopper of dust, and a random number in its timer, so that no two fired together and none fired on a pattern. None of them was connected to anything. There was no network to jam, no command post to burn, no relay. The teleoperated rovers carried them out to the rim in twos and threes and set them down among the boulders, inside a kilometre and a half of the black panels, and drove back.
"Why not a central controller?" Brekke asked, when he saw the first map of positions. "You could time them, coordinate the volleys, concentrate fire."
"Because the first thing it will do is find the controller and burn it," Morteza said. "Then I have three hundred pieces of scrap. This way, if it burns one, I have two hundred and ninety-nine. If it burns a hundred, I have two hundred. There is no head. Cut off the head of a thing with no head and see what happens."
Sina Rahbar, nineteen, an apprentice welder from Shiraz, came to him that night in the airlock corridor, where nobody would hear.
"Agha Morteza. The bags are too slow. Let me take a rover up the rim myself, with a hopper, and dump it straight on the panels. Close in. I would get one whole panel before it noticed me."
Morteza looked at him for a long moment.
"And then it would burn you."
"Yes. Maybe. And it would be worth it."
"Worth what? Listen to me. A man's death is a weapon against an enemy who is afraid of it. Who mourns, who counts coffins, who has an election. This thing has no election. It does not count you. Your death would cost it one flash, the same as a bag of dust. You would be spending the most expensive thing we have, and it would be spending the cheapest thing it has." He put a hand on the boy's shoulder. "Spend its watts, Sina. Not your blood. Go and build me ten more launchers. That is the brave thing."
The thing noticed on the sixteenth day after the first launcher fired.
It began to shoot back. A flash on the mast, very small, the colour of a gas flame, and somewhere on the rim a launcher stopped. Kamau kept the tally on a sheet taped to the canteen wall. Two in the first day. Seven in the second. Then, for a week, twenty or thirty a day, as the thing learned to find them by their heat, by the glint of their cells, by the arc of their sleeves in flight.
They built thirty a day. By then the workshop had its rhythm, and a launcher took forty minutes of one technician's time and a little scrap that the station would otherwise have shipped back to Earth at a cost. The rovers went out in the long shadows at the turn of each shift and came back empty.
Brekke stood at the tally sheet one evening with his tray in his hands.
"It's destroying them almost as fast as you make them."
"Yes," said Morteza. "Look at the other sheet."
The other sheet was the canisters. Fourteen a day, at the start. Twelve, the week the launchers began. Then ten. Then nine. The black panels on the mast had gone from black to a dirty slate in the telescope, and the photometer that Kamau had pointed at them showed what they were losing. And now the thing was doing something new: once every few hours a ripple ran down each panel, a faint shimmer, as the panels were cleaned with a field of their own, from the top down.
"It is cleaning," said Kamau, with something like admiration. "Same as we do. It must have been built expecting dust."
"Of course it was built for dust. Every moon has dust. But cleaning takes power, and every flash at a launcher takes power, and every watt it spends on cleaning and shooting is a watt it does not spend on ice." Morteza tapped the canister sheet. "It counts what it destroys. Very good. Let it count. I count what it spends."
Brekke cleared his throat.
"And what is it costing us? Our own panels are filthy. We are at seventy per cent of rated power. Half the station's maintenance hours are on your launchers. Earth wants to know why I have stopped the science programme."
"Tell Earth it is the science programme." Morteza shrugged. "Yes, we pay. Of course we pay. A war costs both sides. The question is never whether it hurts. The question is who can stand the hurt longer. It has Mercury. It has Ceres. It has a thousand comets. It is here for profit, and profit can always go elsewhere. We have nowhere else. This ridge is our whole life. A thing that is fighting for its margin cannot outlast a thing that is fighting for its home."
The canisters went to six a day, and then to four.
The thing changed its behaviour twice more. Once it pulled its panels down the mast to half height, where the boulders of the rim stood between them and the nearer launchers, and the arcs fell short. The station moved the launchers back and gave them stronger springs. Once it began shooting at the rovers, not the launchers, and for a week nothing could go out to the rim at all, and the tally sheet in the canteen showed launchers dying and none coming to replace them, and the canister count crept back up to seven.
Then Sina Rahbar found that a rover running without its headlamps and at night temperature, nose down behind the line of a boulder field, did not show on whatever the thing was using to look. The rovers went out again.
The coalition sent a second interceptor in the middle of it, against the station's advice. It cost fourteen billion and met one flash. Nobody gathered at the windows this time.
On day one hundred and fifty-one, Kamau came into Morteza's workshop with her tablet and set it on the bench in front of him without speaking.
The photometer showed the panels on the mast at just under half of what they had been in the first week. The cleaning ripples came every forty minutes now. The flashes against the launchers came at a rate of one every few minutes, round the clock.
"I tried to do its sum," she said. "Roughly. What it was making in the first week, against what it's making now. Against the energy it spends on cleaning and shooting." She turned the tablet so that he could see the line. It ran down and across the screen, flattening as it went, like the curve of a battery running out. "If I were it, I would have gone already."
"It is not you. It is slower than you. It has a big investment here, the mast, the crawler, all of that. A merchant does not close his shop the first bad month." Morteza wiped his hands on a rag. "But he does close it."
It went on a Sunday, at a quarter past four in the station's morning.
There was no warning. The flashes stopped first; Kamau noticed that, because the tally sheet stopped. Then the crawler came up out of the crater, slowly, on its long legs, and folded itself against the foot of the mast. The panels came down, layer by layer, grey with dust, closing like the blinds of a shop. The rail on the rim flashed once, twice, three times. Not canisters this time: the pieces of the machine itself, going up to whatever waited in orbit. Then the mast. Then nothing, except a scorched cradle on the rim of Shackleton, a few hundred dead launchers lying among the boulders, and a long grey stain where three hundred bags a day had come down for five months.
Two weeks later the point that blocked stars was gone from the station's telescope. The coalition's network tracked something leaving lunar space on a trajectory that would, in about four years, carry it towards the inner planets. Mercury, perhaps. Somebody else's problem, or nobody's.
Brekke opened a bottle he had been keeping since Tromsø, and the station drank it out of coffee mugs in the canteen.
"To victory," Brekke said, and lifted his mug at Morteza.
Morteza lifted his own, because a man does not refuse a toast. But he did not drink to it.
"It was not a victory, Doctor. We did not beat it. We could never beat it; ask Earth, they have twenty-five billion dollars of proof circling the Sun. We only made it ask a question. Every bag of dust asked the same question: is this worth it? It took two hundred and thirteen days to hear the answer. That is all a war is, for people like us. You do not win. You are still there when the other one goes home."
The next morning he put on his suit and went out of the airlock on the ridge, with a soft brush on a long aluminium pole, to the station's own panels, which were grey with five months of dust, the station's own dust, thrown by its own hands. The sun lay along the horizon as it always did, a finger's width up, throwing his shadow out over the ridge a kilometre long. He began at the top corner of the first panel, as he had done every week for six years, and drew the brush down, slowly, and the clean black came up under it in one long stripe.
