It Was Still Recording. *The processing contract lapsed eleven days before the network did, so the last 168 hours went to tape and stayed there. We paid a seismologist who was not told what the tapes were to read them. Nine long-period events came back.* The memorandum is one page. Six numbered paragraphs, a signature block, a distribution line, and a footer that reads 1/2. Paragraph 3 gives the annual operating cost of the lunar seismic network as $1,060,000 and says that closing it at the end of the fiscal period will avoid that cost in full and affect no other programme element. Paragraph 4 disposes of the last week of the data in a subordinate clause. **Document: Termination memorandum, 8 July 1977, page 1 of 2 — paragraphs 3 and 4, verbatim** ``` 3. Annual operating cost of the network, exclusive of data reduction, is $1,060,000. Termination of station operations at the close of the current fiscal period will avoid this cost in full and will not affect any other programme element. 4. Custody of recorded media accruing after expiry of the reduction contract shall be as set out at paragraph 7. No reduction of such media is authorised under the present contract. ``` There is no paragraph 7 on page one. > **Figure:** One week of data, and every desk it passed through on the way to a shelf — see https://theyburied.com/article/switched-off-still-recording ## Eleven days, then 168 hours The data reduction contract — the money that paid people to turn telemetry into events — expired on 19 September 1977. The four surface stations were commanded off on 30 September. The contractor's closeout delivery ran four days past its own expiry, to 0000Z on 23 September, because the week before that was already in the machine. Then it stopped. The network ran for another 168 hours. The carrier was acquired every pass, the frames were logged, and eleven reels were written in the telemetry building as a matter of course, because writing the reel was operations and reading it was reduction, and only one of those had run out of money. The reels went to a shelf. Accession card 77-2216. They survived the tape-stock withdrawals this desk has reported elsewhere for the dull reason that they were written a year after the withdrawal slips were signed. For forty-nine years nobody has run a detection over them, because the published event catalogue closes at 0000Z on 23 September 1977 and the catalogue is what everyone works from. ## What we paid for We had ten of the eleven reels digitised commercially and stripped of their headers. We then paid a planetary seismologist $2,600 to run a detection over them using the catalogue's own published criteria — the same amplitude threshold, the same three-station coincidence requirement, the same minimum duration — and told her the instrument class and nothing else. She was not told what body. She was not told what year. She came back with nine. ## Nine Nine long-period events in the final week, all meeting the catalogue's own thresholds, none of them in the official catalogue, and none of them in the 1,140 entries of the unofficial compilation this newspaper spot-checked last summer, [[PX-1788]]. The shortest runs nineteen minutes. The longest runs two hours and forty-seven minutes, which would place it inside the top forty of the compiled catalogue if the compiled catalogue extended that far. The ninth began four hours and eleven minutes before the shutdown command and was still above the detection threshold at the final sample. > The file ends inside an event. That is not something I have seen before, because files do not usually end. > > — Dr. Noor Achterberg-Sandoval The moon was ringing when they turned the instruments off, and this newspaper now knows what that ringing costs to explain. Three seismology groups, paid the same fee, kept apart from one another, and working to a criterion registered in writing before any of them saw data, could not reproduce a coda of that length in any solid interior. All three ended at a rigid shell over a void. Their reports run [elsewhere in this edition](/article/all-three-needed-a-cavity). Those three fits were made on nine events drawn from the published catalogue. These are nine more, from a week that is in no catalogue at all, and nobody has fitted them to anything, because until May nobody knew they existed. The record does not stop because the last event stopped. It stops because the money did. ## The man who signed it Wendell Prosser-Kaye is ninety-one. He signed the memorandum, remembers signing it, and says he would sign it again. His reply runs at the foot of this brief and it is the most useful document we obtained this year. He says the eleven days are two appropriations running on two clocks and not an instruction, and we tested him on it: the reduction contract expired ahead of the operations line in five of the eight years before 1977, and the closeout file says so. So the gap is not where this stops. Paragraph 4 is. It sends the custody of a week of unread tape to a paragraph that is not on the page we hold, and no appropriation calendar has ever explained a cross-reference. He also says the memorandum was drafted for him, that the wording of paragraph 4 is not his, and that he never saw page two. He asked for it once, in the spring of 1978, and was told it was not in the file. ## What is still on the shelf The processed run and the memorandum are lodged in our vault entire, including the two of the nine where the analyst's own confidence flag is low. Two things are not there. The eleventh reel is signed out on a slip dated 4 November 1977 to a name and a room number that appear in no directory we have found. And page two, which the page we hold refers to twice and the records centre cannot locate, is under appeal. We do not know what paragraph 7 says. We know that paragraph 4 needed it, that the man who signed the page asked for it once, and that the reels it governs are still where the memorandum left them. ## Sources (invented) - Wendell Prosser-Kaye, Signed the termination memorandum in 1977; retired 1989 — Sent the full draft, the memorandum and the analyst's run in writing; replied by post after twenty-six days, then confirmed the reply by telephone (June–August 2026) - Dr. Noor Achterberg-Sandoval, Planetary seismologist; performed the detection run — Commissioned blind — headers stripped, body unnamed, instrument class and the catalogue's detection criteria supplied and nothing else (May 2026) - Ruthanne Ojukwu-Vance, Archivist, planetary data holdings — Interviewed by telephone twice; produced accession card 77-2216 and the loan slip from the same folder (April and July 2026) - Ellery Vaughan-Kimathi, Retired network engineer; compiler of the unofficial long-period catalogue — Sent the nine detections and asked to check them against his 1,140 entries; replied in four days with his working (July 2026) - Termination memorandum, page 1 of 2, Released under freedom of information after a fourteen-month request and one appeal — Copying fee $18.20. Page two recorded by the records centre as 'not located'. The appeal on page two is open (March 2026) ## Documents cited (invented) - PX-1788: https://theyburied.com/vault/PX-1788 - PX-1844: https://theyburied.com/vault/PX-1844 ## What we could not confirm - Page two. Paragraph 4 of the page we hold cross-refers to a paragraph 7, and the footer reads 1/2. The records centre says page two is not located and has searched two accessions for it. We do not know whether it is a distribution schedule, a cost annex, or the paragraph that says what was to happen to the reels. The appeal is filed and undecided. - The eleventh reel. Accession card 77-2216 lists eleven reels for the final week. Ten were on the shelf and were digitised for this story. The eleventh is signed out on a loan slip dated 4 November 1977 to a name and a room number, and neither the name nor the room appears in any staff directory, telephone list or building schedule we have been able to find for that year. - How much unprocessed tape there is behind these eleven reels. The gap we bought is 168 hours because that is what the closeout delivery left. Whether the same criteria run over the preceding months would return more uncatalogued events is a question nobody has funded, including us; the accession cards give reel counts and not date ranges, so we cannot yet say how long the queue is. ## Right of reply **Wendell Prosser-Kaye, who signed the termination memorandum on 8 July 1977** (Replied by post on 26 July 2026, in longhand, and confirmed the text by telephone on 3 August. Printed in full and unedited, including the parts about us.): > I signed it. I am not going to tell you a clerk signed it, or that I have forgotten signing it, and I would be grateful if you did not write the paragraph in which an old man cannot remember. I was forty-two. I had been told to find a million dollars in a programme that was finishing anyway, and I found one million and sixty thousand of it in the one place where nobody was going to fight me for it. With the same page in front of me tomorrow I would sign it again. > > Now let me tell you what I think you have got wrong, since you have been decent enough to send it to me first. > > Nothing was silenced. A network was switched off because it cost more than the queue behind it and because four instruments that had been sitting in the dust for eight years were not, in the judgement of the people whose judgement it was, worth a fifth of a planetary mission. You may think that judgement was poor. I have thought so myself since about 1991. It is not the same thing as an order to stop listening, and your headline knows the difference and is written to be read by people who do not. > > The eleven days are not a plan. They are two appropriations. Operations ran on one line and data reduction ran on another, they had run on separate lines and separate expiry dates since 1969, and in five of the eight years the reduction contract expired first. Nobody sat in a room and chose eleven days. A contract ended on the date printed on it, which is what contracts do, and the fact that it makes a shape on your diagram does not make it an act. > > You will want to know about paragraph four. So do I. > > That memorandum was drafted for me. I want to be exact, because you will be quoting this: what I did was read it, satisfy myself of the arithmetic at paragraph three, and sign it. The wording of paragraph four is not mine. The cross-reference to a paragraph seven is not mine either, and since you have circled this for two pages without asking me plainly, I will save us both the time. I never saw page two. > > I asked for it once. In the spring of 1978 a query came back from the records people about custody of media and I could not answer it out of the sheet I had, so I asked, and I was told it was not in the file. I did not ask again. I want you to understand how completely ordinary that was, and I want to be honest that it still sounds ordinary to me when I say it aloud, and that it stops sounding ordinary the moment I read it set in your typeface. > > So I cannot tell you what paragraph seven says. I can tell you what paragraph four says, because my name is under it: that no reduction of that media was authorised under the present contract. That is a sentence about money. It is not an instruction to anyone to look away, and I would ask you not to print it as though it were, because a reader will not hold the distinction for more than a line and you know that better than I do. > > On your nine events I have no quarrel and no standing. If the run holds, then what you have established is that a network in good order returned nine detections in its final week and that not one person on the payroll was under contract to notice. That is a scandal about procurement, and it is a real one, and I was part of it. You are writing it as a scandal about knowledge. I do not think you hold the page that would make it one. > > Neither, plainly, do I. > > One more thing and then I will stop. You offered me a right of reply and I have taken it, so let me spend the last of it on the sentence I would least like to read about myself. I was the last man with the authority to ask where page two had gone, and I asked once. --- They Buried is a satirical newspaper. Every story, source, document and person in it is invented.
