Julian date 2459718, Friday. At ten in the evening Zhou Yan transcribed up the S value for line 162: 0.37.
The pen tip left the paper and she paused. She had drawn that line's blank cells at seven fifty-five in the morning; it had stood empty all day, like a question asked into a room where nobody picked it up. Now it was answered—and still 0.37. She closed the notebook and went to the water room to rinse her cup; coming back, a new mail sat on the duty computer, sent forty minutes before. Mateo.
The mail had no salutation. Three lines.
Line one: the negative-result list, forty-two stars, all negative results maintained. Line two: one added—LP 413-52, 11.3 light-years out, the catalog number my own, by distance order. Line three: the shallow cut hits it first; don't test the lens on the main print.
Underneath were four pages of PDF. Page one, a catalog screenshot—coordinates, proper motion, parallax, the parallax column boxed in red. Page two, the negative-result list, forty-two lines, one word at the end of each: binary. Magnetic field. Contaminated disk. Fast rotation. Binary. She counted down the rows one by one: binary appeared nineteen times. An empty line stood at the list's foot; in the number column, handwritten in, the forty-third: LP 413-52. The remarks column held four characters: cooled three hundred million.
Eleven point three light-years. She wrote the number on scratch paper and circled it. GY-1402 stood forty-one light-years out; confirmation of anything carved there would be seen by people outside this generation. Eleven point three light-years was different: the test body carves, and the confirming light walks eleven years four months back, landing in this generation's hands. That account Mateo hadn't put in the mail; she finished it for him and wrote it in the corner of the page: return leg, 4,127 days.
Saturday she photographed the corner and sent it to him. He sent back one word: correct.
The shallow cut used nothing newly built. The first of the calibration sequence's seventeen bodies, refitted ahead of schedule—no content, no encoding, only a profilometer aboard. Inside the engineering they called it calibration unit one; on paper it read shallow-cut test body. The launch window was set at Julian date 2459803, the first Saturday of September.
That month the budget's deferral began to run. The documents kept the three-file tone: the sixty percent cut from the initial appropriation would not be made up; every month of delay slipped the first-strike window four months. At the station they called it walking winded. Four months traded for one—anyone could do that arithmetic, and having done it, nobody said anything. Finance pinned the three tables to the corridor notice board; they hung there a month—nobody took them down, nobody stood in front of them; people passing put their eyes somewhere else. Mateo put it more sparingly at the weekly meeting: money stops one month, the window backs up four, and it backs up until the day the supplemental appropriation lands. Someone asked, and what if it never lands. He said: then it backs up forever. Whatever day it stops on, that day is the window. The supplemental came in January 2023; it had backed up six months; the first-strike window moved from May 2026 to May 2028. The new table was printed, and the footer line—this table shall be executed as scheduled—moved over as it stood, not one character changed. The three old tables came off the notice board, folded, filed into the archive box. The knowledge window grew two years with it, from forty-two to forty-four. Forty-four years on, she would be eighty-five. She wrote that number on the back of the calendar—no name, only the number.
The day the launch began there was no ceremony. The electric thruster on that rocky main-belt asteroid lit; the brightness curve folded into the deep-space monitoring network's routine reports as entry 4,171; nobody forwarded it.
One evening in early September, Zhou Yan opened her own livestream's back end. #OutsideMyWindow#, started in early summer, the poplar, two books wedged under the left of the camera. The viewer count had stood at four thousand a long time; these two days it had fallen to two digits. She paged through the viewer list: forty-one, nine of them gray avatars, hanging idle. The chat's last page stopped three days back—someone had asked: is the poplar okay. No answer. She paged back one more; still that line.
She stared at the back end a few minutes. Who comes to watch a window that says nothing. She moved the cursor onto close livestream, pressed, confirmed, confirmed again. The page snapped home; the recommendation slots held other people's streams—one selling tents, one watching clouds. Her account page stood empty, one line left: this user is not live.
She laid the phone face-down on the desk and went to sleep. The next day Eli asked why she'd closed it; she couldn't get any words out, pointed at her ear, waved a hand. Eli didn't ask again; he turned back to his feed.
In January she went and had the MRI. The slot Dr. Shen had held—he had held it half a year, held it until he himself was about to be transferred away. The registration slip still carried last year's stamp. The films came out; he pointed out the internal auditory canal to her: narrow, both sides, the right worse. He said it was structural—narrow from birth, not something the noise had done; the noise had only moved it up. She asked: moved what up. He said: the right ear's highs you've already lost—above eight kilohertz, the audiometer at its maximum, no response. She asked about the hiss. He said the hiss sounds from inside; when the hearing collapses it stays; you will simply hear it less and less clearly. She thought a moment and said: then it's keeping me company. Dr. Shen didn't take that up; on the chart he wrote: recheck in two years. He closed the chart and added one line: with this illness of yours, the man reading the film knows before you do. She asked what that meant. He said: the structure is sitting there in the open; which way it goes, the film will dare to say before I do. She didn't ask again. She knew that two years on she would still be saying the same thing: another day.
Saturday evening video. Zhou Yao was twelve and took up most of the frame. Zhou Yao asked: what's the test star called. Zhou Yan said: LP 413-52. Zhou Yao said that was far too long—I'll draw it a name. She really did take out paper and pen, drawing as she talked: the two letters for eyes, the numbers for hair. Done, she held it up to the camera. Zhou Yan looked a long time. In the frame her daughter's eyes were closed—Zhou Yao draws everything with its eyes closed; had for two years. Her ex-husband asked something from outside the frame; Zhou Yao turned back to answer him, the voice gone to mush. Zhou Yan pushed the volume to the top before she made out what Zhou Yao was saying: she can't hear you—type.
That line was typed into the dialog box, her ex-husband's hand. Zhou Yan replied: I can see.
Julian date 2460204, 12 October 2023: the first cut, locally. In the engineering's phrasing, nothing happened that day: the test body unfolded into plasma eleven point three light-years out, the profiler laid down its first image—and all of it had to wait for the light to finish walking 4,127 days before Earth got its turn to see. The station put no one on duty for it; telemetry arrival was a matter of February 2035, and the duty roster already ran to that year, its cells empty, one column filled in ahead of time: Xiao Ma.
Xiao Ma was no longer called Xiao Ma—Engineer Ma, twenty-nine, the one in charge of the shallow-cut data. A year and more before, on night shift, he had worked out 468,000 years by hand, circling the data with exactly the stroke Zhou Yan had once used to circle the shoulder; she had never told anyone that. The first thing he did taking over the roster was mark the return date in red, then add one line of remarks after it: two packets, same road; the road can't open a gap. She asked what that meant. He said: the first packet was sent the day the carving was made, the second fourteen months later at recheck; both walk the same eleven-point-three-light-year road, so the interval between arrivals on the ground is still fourteen months. The light path cancels. She said: then why mark it. He said: in case someone takes it for good news coming early.
That day she went back early. In the corridor she ran into Eli coming out with the feed bucket, his face wrong. Lao Wu was failing. She followed him into the little room behind the machine room. The tank water was clean enough to hurt the eyes; Lao Wu lay on his back on the tank floor, antennae strung loose. The notch on his shell still measured two millimeters—two years: it had grown to two millimeters and never grown again. He had molted halfway and stopped; a split had opened between cephalothorax and old shell, and there he had stopped. Eli said he had still moved once toward dawn. Zhou Yan crouched down to look at the split. A crayfish molts by levering the shell open first and pulling itself out through the split; only out does it count as new. Lao Wu had pulled halfway. She said: should we help it. Eli said no—one touch and it breaks; only its own strength can do it.
The next morning Lao Wu was dead. Eli lifted him out; the old shell stayed on the tank floor. He said: I'll keep the shell. The shell is proof that it grew. The empty tank wasn't taken away; the water went on being changed. Until the year Zhou Yan transferred out, that tank still stood there.
At the year-end meeting someone proposed tightening the recheck cycle for the shallow-cut profilometer, from once every fourteen months to once every six. Ursula, at her video tile, said: no need. Measure the second time first. Don't reason with it. The minutes took them down as they stood.
The ten years after that were stretched straight by waiting.
December 2024, local month fourteen: the companion relay ran its recheck and sent the second packet out. This happened eleven point three light-years away; Earth had no way whatever of knowing. That day, as usual, she transcribed the S value—line 1,075, 0.37.
Early in 2031 she left the station for the engineering data group; the S table passed to the duty sequence. Mateo signed the handover sheet and attached one condition: Zhou Yan checks it once a week. She moved house as well. Moving day she packed the S table's originals into the archive box—the pages furred at the edges from turning, line 1 through line 3,200-odd, all of it her handwriting. After the duty sequence took over it went to print, format as before, one line a day. That winter Old Tang phoned: the old man passed last month. He paused, then said: I turned the lamp off for him. She stood on the balcony holding the phone until her feet went numb. That night's S line she made up the next day; it never broke.
Zhou Yao sat her entrance exam in 2024 and applied for fine arts. The choice form was sent over for her to read; she read it three times and said on the phone: quite good. That was all she said. Her ex-husband put in a word from the side: her own decision. Zhou Yao grabbed the camera over and said: Mom, the things I make from now on—will they last a long time? Zhou Yan asked why she asked. Zhou Yao said: the teacher says prints keep for a few hundred years, oils longer. Zhou Yan said: depends on what you carve it onto. Zhou Yao laughed and said then I'll have to pick good wood. She came back to that conversation many times afterward; every time she meant to say something, and didn't.
2033: Amina stepped down as secretary general of the Long Night framework. A reporter asked about that thing she had been writing for eleven years. She said: still writing; no deadline. The farewell press conference ran forty-one minutes; that sentence held four seconds of them. Two years later that thing's whereabouts were unknown; it was not on the office clearing-out list.
At the 2034 physical, the left ear began its slide at four kilohertz. The doctor laid the two audiograms side by side for her: the right one had collapsed back in 2022; this left one was walking down the same slope. She asked how many years. He said: that depends how well you protect it. She said: I protect it very well. The doctor didn't take that up; on the chart he wrote: recheck in two years. She laughed. Another day, she said. This time the doctor understood, and laughed too. The hiss she had long since stopped counting—stopped at day 4,000. After the right ear collapsed it was still there, only it had changed its way of sounding, like something behind a wall.
Some things hadn't moved in twelve years. The draft called "Shoulder" still lay in 3t, its timestamp stopped at October 2021, its file size 2,041 bytes; each year she glanced at its properties in passing—unchanged. The 2004 duty-log page had been digitized; the scan's resolution fell short, and the difference between the two pens beside the word Noted had become harder to see on screen than it was on paper. She saved that page three ways: one to Old Qiao's successor, one to the archive room, one she kept herself. Physical evidence doesn't age; it only slowly gets harder to see.
The year the left ear began its slide she was fitted with a hearing aid; the right ear got none—there was nothing left to aid. At meetings she sat in the front row and read lips. Mateo noticed, and had his briefing font enlarged two sizes; beyond that he said nothing.
Julian date 2464331, 16 February 2035, 4:17 in the morning: the first packet arrived.
What arrived was radio—first to the antennas, then to decoding, then to the screen. The signal had walked eleven years and four months without one pause on the road; the ones who paused were the people. The people who had waited eleven years and four months sat unmoving through the minutes of its landing. On duty was Xiao Ma. At 04:19 he finished the checksum; at 04:31 he woke the whole group. By the time Zhou Yan arrived, eleven people stood in the machine room; no one spoke. On the screen, the profile: one groove, 210 meters long, 6 wide, 3.4 at its deepest, and on either lip a plume sediment ridge 0.8 meters high. The depth map was colored by scale; the groove floor ran dark red. It's carved. That was Xiao Ma's post to the group—no punctuation after it.
No livestream. Ursula's line—the day I count it out, nobody opens a livestream—still lay pressed on the engineering's memo page; twelve years on, no one had touched it. Hu Yisu was awake that pre-dawn too; he opened the old 2022 desk clip, pinned it, and eleven minutes later took the pin off. She learned of that later, from someone's screenshot.
Mateo had joined no wake-up call. He downloaded the full packet himself and reran the profile; two hours later he posted the two versions side by side: identical. Kramer asked for the raw data; the next day the full set went to him, checksum frames included. Someone asked whether to hold a press conference. Mateo said: wait for the second packet.
At ten that morning the canteen television was playing a montage of old news, the sound off; the captions rolled to the fifth clause of the 2022 proposal, and when the second half of the last sentence came up, a young duty watcher copied it out onto the whiteboard, and at the sentence's end drew a check mark. Nobody erased it. The line stayed on the whiteboard to month's end, until the next round of duty rosters was pinned over it.
The S table that day stood at line 4,775. 0.37.
The second packet came fourteen months later. Julian date 2464758, 17 April 2036, 3:06 in the morning.
In those fourteen months no one brought up the shallow cut. Not forgotten—simply not mentioned. It held a fixed line in the engineering's weekly: LP 413-52 telemetry cycle normal. Checking the S table each week, Zhou Yan gave that line one glance in passing, then went on checking her numbers. Window day was a Saturday; Xiao Ma on duty, two cups of coffee standing on the desk—one his, one that nobody drank.
Xiao Ma on duty again. This time he woke no one; first he stacked the two profiles together and ran the difference map, and only at 04:50 posted it to the group. Zhou Yan had been shaken awake by the phone; the hearing aid wasn't in; the world was flat; the screen's light was the only sound.
The difference map had one color only. The groove was still there—still 210 meters long, still 6 wide. In the depth column, 3.4 had become 2.9. The sediment ridges on either side stood 0.3 meters lower. The polyline of the groove lip had rounded over by one layer in the plot, like a line traced a second time.
Half a meter shallower.
No one spoke. Ursula was online; she sent one line only: measure the third time first. Someone asked what was pushing it flat—thermodynamics or the shell's stress, evaporation or creep. She replied: none of that guessing. Mateo came online last and posted one line: the recheck cycle changes from fourteen months to ninety days; the third packet arrives October 2037. Then that account went gray. Kramer took away both full packets, saying he'd have his student run a forward model; his annotation ran half a sentence: we'll talk when the model can't keep up with the data.
After daybreak Zhou Yan printed both profiles and pinned them side by side on the lightbox. She looked a long time. That half meter of shallowing was like the ring a cast leaves on the forearm after the cast comes off—don't rub it, don't touch it, and in a month it smooths itself flat. Skin is alive; under the dent there is something pushing it away. But the shell is dead—dead three hundred million years. Dead things have no underneath.
Saturday evening video. Zhou Yao was twenty-six, at a printmaking studio in the south; the camera held steady; the background didn't shake. She held up a newly cut print for Zhou Yan: a person with closed eyes, standing before a pane of lit glass, two sheets of paper pinned to the glass. She said: it's of you. Zhou Yan asked why the eyes were still closed. Zhou Yao said: when I start carving I mean to open them; the knife goes down, and they close anyway. The captions were on, jumping line by line. Zhou Yan watched that line and nodded.
The video hung up, she went back to the lightbox. On the difference map she drew three pencil circles: one around the 2.9, one around the stretch of lip where the polyline had rounded, one around the 0.3 the sediment ridge had lost. Done, she turned the record book to a fresh page and wrote up the day's date and the line number.
Line 5,202. 0.37.
