Before April, the station closed out its last old account.
April's first package had been sent in January and arrived this month. In the depth column, for the first time, what was printed was not a number but a line of text: below threshold.
The threshold was 0.05 meters. A groove shallower than that, the instrument could not tell from the floor. Engineer Ma looked at the line a long time, then drew his extrapolation sheet from under the glass and added one more line beneath the last, in his own hand: January, below threshold. Done, he slid the sheet into an archive bag and sealed it. The sheet had sat pressed under glass for a year; it had reached its archiving day. The day anyone could have computed had come.
The extrapolation sheet had been made last spring. The night he finished the math he had traced the last line in heavier stroke and sent nothing to the group. At handover next morning he wiped the glass once, pressed the sheet back down, and said one sentence: The sheet's here. Whoever wants to look, look. In that year few had looked. Those who looked said nothing. In the cell where the line on the sheet ran to its end stood a year and month—no "zero." What he had written was: below threshold, or zero. The instrument's word stops at the threshold; past the threshold he would not say one word more.
No one at the station took it for bad news. Whether the groove was still there would have to wait for word from whoever could see. The ones who could see were on their way.
Kramer reposted an old news item, the press release from the day eleven years back when the shallow cut produced its result, with one line of his own: This time, there's no "It's carved" to wait for. His reposts these years had come to look more and more like archaeology. Ursula's avatar lit once, two minutes after the message went out, then went dark again, no words. Four years retired, her avatar had become a lamp at the station—it did not speak, it only said present.
The days on the countdown page shrank one at a time. First three digits, then two, then one. The week the digit count fell to one, people at the station started walking fast again, same as last November. That week everyone who checked a watch checked it twice—the first time for the time, the second to confirm the first. The duty officers stopped adding notes to the end of the daily report—since the format had switched to days, everything that could be noted had been noted. The rotation sheet ran at full load, seven people, seven days a week, the signature column re-papered monthly.
Zhou Yan went to the machine room every ten days to listen through the full sequence, forty-four impactors, half an hour. She spent the left ear sparingly; the listening check sat in the morning, one session a day. Afterward she took the equipment off and leaned on captions the rest of the day. The one taking over was a graduate student with good ears—three sessions a week shadowing her, half a notebook of notes. She signed the annotation rights to her listening-method files over to him with one line attached: What you hear, recheck first, then speak. The sequence since number 29 was rescheduled had been even for half a year. Each time she reached that stretch she still played it once more. Listen to anything even long enough and you start hunting for the uneven in it. She had told the graduate student: Hold it in. The uneven comes out on its own.
The vote was set two weeks before the window opened.
The standing legacy committee, final review of the content list for the impactor information vault. The list held a star catalog, the periodic table, the calibration headers of 20,041 synchronized-observation records, four minutes of audio. The image class kept one slot; seven candidates in the catalog; listed first was the one with open eyes.
How the picture entered the catalog took a small scroll of correspondence in the files. The vault team, screening images, came on a public story from four years back—among the illustrations, hanging on the background wall, was this one, captioned: the discoverer's office. The team wrote the artist to ask consent for candidacy. The reply was one page, few words: I consent to candidacy. If selected, no further interviews. The signature was no name—it was a plate number. The vault team spent half a day on that plate number and traced it to the door plate of a printmaking studio; the numbers matched. In the file, that one reply page was later checked out eleven times, and every time the stated reason read: verify plate number.
The dispute had been there from the day the catalog was printed. Seven candidates: a survey mosaic of Andromeda, an electron-microscope image of the DNA double helix, a photograph of a reef by the sea, a Song-dynasty star chart, a replica of the Arecibo message, a children's drawing—skies drawn by children everywhere, pieced into one wall. The seventh was the one with open eyes.
The opposition's case was laid out square: this is a vault for the whole species; a private work does not belong in it. Put a human face on it, and what the outside reads is a face. The artist had no standing, the work was too recent, the review cycle abnormally short. Someone said it more plainly: the first six belong to everyone; this one belongs to one person. The affirmative was one sentence, Mateo's: Twenty million entries in the vault, and all of them numbers. What's missing is a person who looks at the numbers.
In the second hour someone brought up the picture's history. Before it stood nineteen years of closed eyes; she had drawn closed-eyed people for nineteen years, and the first open one she gave to now. Someone on the opposition said that was more reason not to choose it—a private turning. Kramer was in his seat. He said: Every entry in a star catalog is a private turning—where else would the numbers come from. And: The first six were made by people without names. This one only happens to have one. The room went quiet. Before the vote one last objection was raised: what if it reads as provocation—eyes open, looking back at them. Mateo said: We're throwing forty-four lumps of iron at a star, and what keeps us up at night is that it might find our looking too straight. The stenographer later copied that line out on its own; whose habit that was, no one knew.
Before the vote she recused herself. The picture was her daughter's; she was an interested party; a slash went through the signature field. She said nothing the whole session. At the close, someone in the corridor asked her view. She said: Someone in my family drew it. I keep my mouth shut.
The vote was by roll call, one vote per house, each house raising its card as its name was read. The first three—the survey mosaic, the double helix, the reef—passed without dissent. The star chart took one objection, reason given as "already a common holding"; no argument. The Arecibo replica passed with more than half; someone moved to add the transmission year as an annotation; carried. The children's drawing wall passed unanimous—the loudest objector raised his card too. The seventh: when its name was read, the room held quiet a few seconds, then house by house the cards moved. Nine houses raised. Four did not. Of the four, one attached a line to the record: No objection to the content—only to the haste. The stenographer copied that one in full.
Nine to four. In—first place in the image class. One rider passed: the seventh would travel with an added print from the closed-eye years, the artist's choice. The chosen piece got no vote; the artist's wish was executed as given.
Waiting for the elevator after the session, Mateo stood beside her and said: From now on there's a person in the vault. She said: The vault was always people. He nodded and stepped in first. Before the doors closed he said: I know. I mean—from now on, they can be seen.
The vault's physical form was etching: thirteen impactors carried the content, faces up. Once landed they would sit unmoving, face up, weathering counted in hundred-million-year units. She later read as far as the line on etching density in the technical description, took one look, and set the description down—pressed into that face smaller than a palm was an order of magnitude more than the whole cabinet of paper records in Shanghai. A cabinet of paper, pressed into a fingernail.
Saturday video. She told Zhou Yao the result of the vote.
Zhou Yao's end was quiet a while. The workshop lamp behind her; a row of new blocks leaned on the rack, all wrapped facing in. Her master had stopped coming last year; he had left her the keys and said from now on the work in this room was hers to schedule. Zhou Yao's first question was: How big will it be cut. Zhou Yan typed: To the scale of the original, reduced to the carrier's limit. The eyes take up less than a millimeter. Zhou Yao said: A millimeter is enough. She thought, then added: Don't touch up the eyes. Cut each stroke as it comes; leave the place where the knife broke, too.
Zhou Yan said: All right.
Zhou Yao sat a while longer, then said: The closed-eye ones—if one can come along, bring one. Zhou Yan asked why. Zhou Yao said: They're the nineteen years in front of it. Without those nineteen years, no one would know this open one. Zhou Yan typed the sentence out one character at a time, and when it was done asked nothing more.
The signature field the committee had asked about by letter. Zhou Yao's reply: sign the plate number. The block has a number, the number has a ledger, the ledger sits in the workshop's book. No person signed. The committee complied. When the catalog was reprinted, what stood under the seventh was a string of plate numbers, nothing else. A reporter traced it to the door; Zhou Yao pasted a sheet of paper on it: the studio receives no visitors. The signature there was a plate number too.
When the etched vault faces passed final inspection, they were photographed. The vault-face photo of the seventh impactor was printed twice—one into the archive, one mailed to the artist. The photo came printed together with a magnifying lens; under the lens, the space that eye took up was little larger than a grain of sand. Saturday video, Zhou Yao held the photo to the camera and looked a long time, and said: It's there. That was all. She stood the photo on the block rack, leaning against the closed-eye print she had chosen—the last one from the nineteenth year, a sleeping profile. The two hung side by side, one closed, one open, with a roll call between them.
The week after the vote, the station lived its ordinary days.
The museum wrote: at the wall of paper-record cabinets, visitors had grown, and the question asked most was—why are those two cells empty. The museum answered by the book: ink blot, not a number. Someone unsatisfied pressed: does that count as missing. The museum passed the question to her. She wrote back: It's not a lack. It's as-is. The museum printed the sentence at the end of the docents' script. Lu Weiming heard of it and sent word through someone: Good answer. Don't change it.
The left-ear recheck came due, a mid-April appointment; she went as scheduled. The low frequencies were still there; the fall had slowed against the previous two years. The doctor said: It wants to hold out until that day too. She didn't take that up, only asked: How much longer will it hold. The doctor said: At this rate, longer than you think. She entered the sentence as line seven of the listening-method file: low frequencies, longer than you think.
The gatekeeper's register started a new volume. The graduate student brought his own equipment into the machine room for the first time, signed in, and under purpose first wrote listening, thought a moment, and added one word: listening, learning. The gatekeeper looked at it and said: Your teacher's line was short too.
The day the window opened was April 29, a Thursday. Hu Yisu's shift.
The window ran eleven days: first impactor in, last impactor out, two hundred-odd hours between. Window is an engineering word; it means the margin left for error—every arrival follows the table, and the table leaves each one a door. The door opened on April 29.
The afternoon at the station went on as usual. Boiler-room maintenance, the spring calibration of the feed line wrapping up, one extra dish in the canteen. No one said what day it was; the extra dish was itself the whole of it. An old-timer at the serving line added one sentence: They served this dish twenty years ago too, the day the broadcast went up. The cook said: I remember. That was all. Same recipe—what it was twenty years ago is what it is now.
At ten in the morning she had checked the S table as always and signed. Signed, she gave the line number one more look: line 7,395. The first line had been entered twenty years ago, in the small hours of that morning. Ten-thousand-odd 0.37s—one person, one pair of hands, one line a day—kept down to today.
Handover at five thirty. The handover record ran to the forty-fourth; last line: Full chain in orbit. Nothing pending. Signatures, two rows—the one handing over and the one taking it. The one leaving wiped his chair before he went. The chair wasn't dirty.
The S table checked to line 7,395. 0.37. Signed.
She capped her pen and sat in the machine room a while. She had listened through the tones of the forty-four stars once that morning; all walking, all even. The photocopy of that list in the 3t folder she hadn't touched these past days—some words are saved for later, and today was not their day.
The desk calendar she had turned once in the afternoon. The folded corner of the April page had been folded a year ago. What she wrote on the calendar that day was not a date but a number: one. The day the countdown reached one. Today she flattened the page out to look; the crease had been pressed dead and would not smooth. The mark stayed in the paper. She closed the calendar and left it alone.
At night the machine room held more people than usual. No one had called them; no one left. Chairs ran short; the latecomers stood against the cabinets. Hu Yisu was on console; the others treated him as not there—on duty he was part of the machine. After eleven thirty the room held nothing but the ventilation and the clock.
At 23:40 the first one entered the window. The number on the countdown page stopped at zero; it jumped to no other word. The duty log turned to a new page; the duty officer wrote the window number at the head, then the frame number. The first frame was empty—by the table, the first impactor's terminal maneuver lay twenty-seven hours out; tonight it had only walked through the door. An empty frame still gets recorded. The procedure said so: the record starts from zero. Hu Yisu had added that line half a year before. He had given his reason once, when he wrote it: back when we were checking Wangshu-7, what we lacked most was the first frame. The first frame is the frame where there is nothing. Nothing, too, has to be written down.
At the console, the screen's light fell on the notebook in Hu Yisu's hand. The notebook was new; the first page held the frame number. At 23:41 he wrote 001, closed the notebook, and said to the man beside him: Logged.
No one spoke. After a while the young man standing against the cabinets left first—morning shift tomorrow. Then, one at a time, the rest went, each giving a nod toward the console on the way out. She left last. Before the door she looked back once: the screen lit, the frame number stopped at 001, and the next line was twenty-seven hours away.
Day one of the window. First frame. 001.
