# USS Kestrel FRG-07 > The bridge display of the deep space research frigate USS Kestrel, holding station at an anomaly at Barnard's Star in 2166. An interactive science-fiction story told through an interface: eight screens of live readings, a captain's log, a crew of sixty-two and real physics. The Kestrel is a deep space research frigate. In March 2166 Fleet sends her to Barnard's Star to survey an anomaly that twice hid the star's light for eleven minutes. She arrives in June, finds four contacts keeping station around the anomaly, and sends the probe PRB-3 across its edge. The probe answers from inside. Each reply arrives eleven minutes earlier than light could bring it, about three minutes before the request is sent. The reader stands the watch. The story is in the readings: a silent relay, a jammed airlock, a fifth contact closing, an echo that counts down. Each screen holds one small fact, and the facts meet in the reader. ## Facts - Ship: USS Kestrel, hull FRG-07, 320 m long, 84 m in beam, 62 aboard. - Commanding officer: Captain Ilse Varden. - Setting: Barnard's Star, six light-years from the Sun, from March to July 2166. - Form: one web page.

Relay 04 is silent. - [Probe](https://kestrel.wellcrafted.pro/#probe): The probe PRB-3 inside the anomaly: its telemetry, its spectrum with one line at 8.42 GHz, and replies that arrive eleven minutes early. - [Watch](https://kestrel.wellcrafted.pro/#watch): The watch bill and schedule, the change of watch, and the echo as spacetime diagrams, one a day since 6 July 2166, when the replies were first timed: the reply reached the ship before the ping that caused it, and each day it arrives later, toward the light-time return. - [Crew](https://kestrel.wellcrafted.pro/#crew): The register of sixty-two by department, and the pages of eight named crew with their portraits and recorded personal logs. The reader works through every log as a security officer, and each entry is marked read once opened. A duty roster lists all sixty-two aboard by department, station and watch. - [Life](https://kestrel.wellcrafted.pro/#life): Life support and the cryo pods: air, radiation dose, the cryo plant and a console for each pod. Pod two holds a rating in for cold exposure from the A3 lock. - [Anomaly](https://kestrel.wellcrafted.pro/#anomaly): The anomaly itself as a radial display, with an instrument of hexagon tiles that sends tones into it, and the chrono tunnel: each note and its reply slide back into depth, the reply landing at the echo's measured return, ahead of the light-time. ## The captain's log Kept by Captain Ilse Varden. 11 entries, oldest first. On the display each entry is read aloud. ### Sealed orders 14/03/2166 (day/month/year) · Ceres Yard · Sol Sealed orders opened at 0600. Kestrel is detached from the Fourth Survey Group and assigned to Barnard's Star, six light-years out. The long-baseline arrays report the star's light disappearing twice for eleven minutes and then returning. Fleet command wants an investigation at close range. I wonder what could hide a star for eleven minutes. This is going to get interesting. We carry a full science complement and a full battery. Department heads are briefed. All hands have leave to settle their affairs before we sail. ### Departure 19/03/2166 (day/month/year) · Outbound · Sol Cleared the yard at 0412 on the main drive. Sixty-two aboard, stores for fourteen months, three probes in the hangar. The crew is in good order. Several are on their first deep transit, and the section chiefs have orders to watch them closely through the first weeks. The first month of quiet is the hard part. They will find their feet. ### Relay chain 02/05/2166 (day/month/year) · Deep transit Seventh relay away astern. The chain carries our reports home and brings Fleet command's orders out to us across six years of light. Relay 04 is slow to answer its handshake. Engineering suspects a cold oscillator and is monitoring. I am adding a daily check of the whole chain to the watch orders. One slow relay in twelve is worth watching. ### Arrival 27/06/2166 (day/month/year) · Barnard's Star · heliopause Out of transit at the edge of the system at 0215. The anomaly holds four light-minutes sunward of our position. It is a dark disc against the star field. My first thought is a black hole. Radar, infrared and the gradiometer all read background, with zero measured pull. The gradiometer measures tiny changes in gravity. A black hole should give us something to measure. Standing order: compare the ship's strontium clock with the relay-chain time signal every watch. Engineering has the chronometric compensator armed to engage at a drift of one part in a billion. We hold position until Dr. Raman's team has measured the anomaly. ### First survey 30/06/2166 (day/month/year) · Barnard's Star · 0.9 AU Four hard contacts are orbiting the anomaly. Each has the radar cross-section of a cutter. They hold formation while the anomaly drifts. The clock comparison remains at zero drift every watch. There is no measurable time dilation at this range, which makes the black-hole explanation less likely. Battery moves to standby and the sensor watch is doubled. ### Probe away 03/07/2166 (day/month/year) · Barnard's Star · 0.6 AU PRB-3 launched from the hangar at 1120. Screen lit, both thrusters answering, clean separation. The probe crosses the edge of the anomaly in two days. Telemetry will be monitored on channel A. ### Airlock fault 05/07/2166 (day/month/year) · Barnard's Star · 0.6 AU The aft lock in A3 jammed at the exact minute PRB-3 crossed the edge of the anomaly. The bay shows a pressure drift. All hands are accounted for and the bay is closed off. The B1 sample containers also warmed at that same instant. Two independent systems changed state together. We have no explanation for the connection. ### The echo 06/07/2166 (day/month/year) · Barnard's Star · holding PRB-3 is answering from inside the anomaly. The probe is intact and fully functional. The replies arrive eleven minutes before the requests that caused them. Raman calls this an advanced signal. The ship's clock remains synchronized with the relay chain, so the effect is in the signal path rather than the ship. Relay 04 has also gone quiet. Kestrel is holding position. ### The spectrum 07/07/2166 (day/month/year) · Barnard's Star · holding The anomaly produces no detectable radio emission of its own. The only narrowband signal coming back is our 8.42 GHz carrier. It is returning our transmission. The echo lead is also shrinking, from eleven minutes toward seven. The science team is fitting the trend now. ### The schedule 08/07/2166 (day/month/year) · Barnard's Star · holding The watch schedule now contains an entry reading PRB-3 RECOVERY, 0412. That is the minute we cleared the yard at Ceres. Someone or something has put our departure time into our schedule. A frost ring has formed in A3 measuring 5.9 meters across, the same diameter as the docking collar on the far side of the ship. Engineering confirmed the measurement with two methods. The echo trend reaches zero on 14/07 at 0600 if the current rate continues. ### The fifth contact 09/07/2166 (day/month/year) · Barnard's Star · holding A fifth contact is inbound from the direction of the relay chain. It has the same radar cross-section and return signature as the four objects around the anomaly. The four have remained stationary for nine days. The fifth is moving toward us. The echo lead has fallen another eighty-four seconds and the current fit reaches zero on the thirteenth. Raman thinks the anomaly is alive and learning from us. Reyes and Raman independently give the fifth contact an arrival date of the thirteenth. I am keeping the ship at readiness. ## The crew 8 of the 62 aboard have a page. Each keeps a personal log. ### Ilse Varden Commanding officer · COMMAND · service number K-0071 · 23 yr · Kestrel 3 yr · born Tromsø, 2124 Ilse Varden grew up in Tromsø above the Arctic Circle, where her father ran the harbour pilot boat and her mother taught navigation at the fisheries college. She joined the Fleet at nineteen as a watchkeeping officer and spent her first commission on ore haulers between the Belt and Mars, where she learned, in her own words, to be bored carefully. Her first command was the relay-laying run to Wolf 359 in 2151: fourteen months out, eleven relays laid, nobody lost. The second was a survey of the Kuiper mining lanes that ended with her ship towing a stricken freighter home for six weeks. Fleet gave her the Kestrel at Ceres in 2163, fresh from her refit in the yard, with the sealed-orders commission already on the books. The crew know her by two habits. She walks the whole ship at every change of watch, and has done so for twenty-three years, which means she knows every hatch that sticks and every rating's name. And she reads the logs of her predecessors, all of them, on every ship she has commanded; on the Kestrel there were none, so she has been writing them for whoever comes next. She has a daughter at the fisheries college in Tromsø and has not seen the town in nine years. She keeps a photograph of the pilot boat in her cabin and nothing else on the walls. Standing order: Hold station at the hold-off and keep the crew whole until Fleet answers. Watches for: The frost ring closing before the echo reaches zero. #### Personal log, 14/03/2166: Orders The orders are simple: investigate, record, hold half an AU clear, return. I have entered the date in my own log so there is a second record of when we received them. #### Personal log, 09/07/2166: The fifth The fifth contact matches the four objects around the anomaly and is approaching from the direction of home. Fleet has no record of it. I asked Raman and Reyes independently for an arrival date. Both give the thirteenth. We stay here until we understand what is coming. ### Tomás Reyes Executive officer · FLIGHT · service number K-0184 · 17 yr · Kestrel 3 yr · born Valparaíso, 2129 Tomás Reyes was born in Valparaíso and went to sea at sixteen on his uncle's coastal freighter before the Fleet took him at twenty with a helm rating and no patience. He flew shuttles at Luna for two years, then transferred to deep survey, where patience is the whole job. He was flight officer on the Alder and then the Tern, both survey ships, both long commissions, and qualified on every helm station the Fleet has, including two it no longer uses. He is known for teaching: every junior watchkeeper on the Kestrel has stood a watch with Reyes beside them saying nothing until they got it right. He keeps the watch bill, the ship's running order and, in his own notebook, the burn numbers for every way out of wherever the ship is. He argues the margin with the captain in private and never in front of the watch, and when she decides against him he carries the decision as if it were his own. His wife Marisol teaches music in Valparaíso. Their daughter is nine. He has her school concerts sent up the relay chain and plays them in his cabin with the door shut. Standing order: Keep the helm within the hold-off on thrusters alone, every watch. Watches for: Eleven days of station-keeping on a drive at idle. #### Personal log, 19/06/2166: Watch bill I have tightened the watch bill for the hold-off. Four-hour watches, single watches for all hands, and junior helm paired with someone who has kept station before. The crew is adjusting to the transit. The schedule should keep everyone sharp without wearing them down. #### Personal log, 09/07/2166: The case The fifth contact reaches us on the thirteenth. Three fixes give me a trajectory using Gauss's method. Three observed positions are enough to work out where an object is. A curve fit through the later fixes gives the same arrival date. I recommended breaking station and making for the relay chain. The captain is holding position. I have the escape burn ready if that changes. ### Mara Ekwueme Chief engineer · ENGINEERING · service number K-0203 · 19 yr · Kestrel 2 yr · born Enugu, 2126 Mara Ekwueme trained as a reactor engineer at Enugu and spent twelve years in the Fleet yards at Ceres, where she rose to lead the refit teams. She has rebuilt the drive spines of nine ships. The Kestrel was the last of them, and the one she asked to sail with, which the yard had never had an engineer do before. She told the yard superintendent she wanted to know whether she had done the work right. The crew believe the truer reason is that she did not trust anyone else to look after the ship, and they are not wrong. She knows the Kestrel from the keel out, and the feed line she welded on the drive spine at Ceres is the one she touches on her rounds. They say she can hear a pump going wrong from two decks away. She can. She was deaf in one ear as a child and had it repaired at eleven, and she says that having heard nothing for a while, she has never since taken a sound for granted. She measures everything twice, writes both numbers down, and does not round. The ring in A3 has been five point nine meters on every measurement she has taken, and she has taken one every day. Standing order: Keep the reactor at three quarters and the ship ready for a full burn, for as long as it takes. Watches for: The containers in B1 warming with both coolers running. #### Personal log, 02/05/2166: Her I refitted Kestrel at Ceres and know the ship's systems well. The feed line is holding and the reactor is running normally. Tanaka asked why I sailed on a ship I had repaired. I wanted to see how the work held up under a real mission. #### Personal log, 09/07/2166: Idle B1 is gaining heat that I cannot account for. The cryocoolers are operating normally, and the measured heat balance leaves an unexplained input. The frost ring in A3 is 5.9 meters across. Tape and laser agree. Curious. That is the same diameter as the docking collar on the far side of the ship. The captain asked how quickly I can take the reactor from idle to a full burn. Forty minutes safely, twelve if she accepts the risk. The chronometric compensator has been armed for twelve days and has never detected time dilation. ### Kavya Raman Science lead · SCIENCE · service number C-0012 · Civilian · Kestrel 1 yr · born Bengaluru, 2131 Kavya Raman is an astrophysicist, born in Bengaluru, trained at the Indian Institute of Science there and then at the long-baseline observatory on the far side of the Moon, where she spent six years. It was her analysis that first showed the lost starlight at Barnard's Star: a patch of sky a few arc-seconds across where the star's light simply stopped, with nothing in front of it. She published, was disbelieved, published again with three more years of data, and was believed. When the Fleet drew up the Kestrel's commission she asked to come and look, and the Fleet, which does not often carry civilians, carried her. She is the only member of the science team who has been outside the hull. She went out with the deck crew to seat the second probe's dish because she wanted to see the dark patch with her own eyes, wrote "patient" in her notes, crossed it out, and put it back. She checks every calibration three times and is the first to say when she does not know. The crew trust her for the second thing more than the first. Standing order: Find one thing the anomaly gives off that is its own. Watches for: That everything it returns is ours. #### Personal log, 11/04/2166: Outside I went outside with the deck crew to install the second probe dish. Barnard's Star was visible off the port bow, with the anomaly beside it. Until now I have studied that dark patch as an occultation, a temporary loss of starlight on a light curve. Seeing it directly changes the scale of the problem, but not the measurement. #### Personal log, 09/07/2166: Five I think the anomaly has two different masses. Gravitational lensing gives us nineteen solar masses. The motion of the four objects gives us less than two thousandths of an Earth mass. I checked both calibrations three times. The two measurements describe completely different amounts of gravity. I don't know how both can be true. The echo is also moving toward zero. The last four days point to the thirteenth. The anomaly is returning our signals and information from the ship. I think it is learning from us. I don't have a mechanism for that yet. So I need another prediction. If I'm right, the response will not be a reflection but something new. ### Signe Halvorsen Sensor officer · SENSORS · service number K-0416 · 9 yr · Kestrel 3 yr · born Bergen, 2136 Signe Halvorsen comes from Bergen, from a family that kept the lighthouse at Marstein for four generations until it was automated. She grew up listening to the sea on a bad radio and says that is where she learned to find a weak signal in noise. She trained as a sensor officer at the Fleet school in Stavanger and served on two patrol ships in the inner system before the Kestrel, where she has run the bow array for all three years of the commission. She wrote the sweep routine the scope runs now, in her own time, because the issued one lost contacts in the sidelobes and nobody else minded. She logged the four contacts on the first sweep after the ship made the hold-off, and has tracked them every pass since. She loses nothing twice: when C-03 dropped out of the sweep, twice, she found it again both times, logged where it had been, and did not believe for a moment that it had gone anywhere. She is patient in a way that reads as quiet. Her grandmother told her the sea always tells the truth, in its own time, and she has started to think her grandmother was talking about something else. Standing order: Hold the four contacts in the sweep and log the fifth every pass. Watches for: A fifth contact with no drive, closing every pass. #### Personal log, 30/06/2166: First light Four objects are orbiting the anomaly. Radar gives us their range, velocity and cross-section. Cross-section is the apparent size an object presents to radar. All four are consistent with cutter-sized craft. They appeared on the first survey and have held position since. I still don't know where they came from. #### Personal log, 09/07/2166: The fifth The fifth contact is identical to the four objects around the anomaly. Same radar cross-section, same return signature, same correlation peak. The correlation peak is how closely two radar returns match. This one is effectively exact. The difference is that this one is moving toward us at 247 kilometers per second. The fleet register has no match. I can tell you what it looks like. I can't tell you where it came from. ### Kofi Imani Ship's surgeon · MEDICAL · service number K-0287 · 10 yr · Kestrel 2 yr · born Kumasi, 2130 Kofi Imani qualified as a surgeon at Kumasi and joined the Fleet medical service at twenty-six, mostly, he says, because the ships had better operating theatres than the hospitals he could get into. He served on a hospital ship at Mars during the Hellas outbreak and then on two survey ships before the Kestrel. He is the ship's surgeon and its medical officer, which means sixty-two people, four cryogenic pods, and a sickbay with eight beds. He sees every member of the crew once a month whether they like it or not, and has a way of asking how someone is that makes them answer. He has never put a person into one of the pods, and runs the readiness cycle on them in turn, a reference profile cooled, held and rewarmed, so that if the day comes they will work. He would like to finish the commission without using one and says so to the pods when nobody is about. He keeps the sleep figures for the whole crew and puts them in the report, and the captain reads the report. He is the only officer who calls her Ilse, and only in sickbay. Standing order: Keep the four pods ready and the crew fit for the burn home. Watches for: Being asked whether the frost is spreading. #### Personal log, 28/03/2166: Rounds Sixty-two aboard, sixty-two seen. Two have sleep problems and one has a persistent wrist injury. No one is medically restricted from duty. The four A2 pods are operating within their reference profiles. I will continue the baseline tests through the transit. #### Personal log, 09/07/2166: Sleep The crew is sleeping less and taking longer to fall asleep than during transit. The change is across the crew, including the officers. I compare each person with their own normal sleep pattern. That tells me how much this has changed them. Everyone remains fit for duty. They are tired, and the reason is obvious. The captain asked how quickly I can prepare all four pods. Forty minutes. If I have to use them, I will have to decide who goes in them. ### Rémi Dubois Chief of the deck · DECK · service number K-0095 · 21 yr · Kestrel 3 yr · born Marseille, 2124 Rémi Dubois was a deckhand on the Marseille tugs at fifteen and a bosun in the Fleet by twenty-five. He has served on six ships, run the deck on four of them, and says the Kestrel is the quietest, which from him is a complaint. He runs the bays, the hangar and the lock crew: everything that opens to the outside and everything that moves through it. He launched PRB-3 from the hangar cradle himself, by hand, because the auto sequence wanted a confirmation he did not have the patience for, and it was the cleanest release the ship has had. He is thorough and says little. His crew drill until the drill is boring, and then they drill again, and when something goes wrong on the deck it is usually over before the bridge has heard of it. The outer lock door jamming open with nothing wrong in it is the first thing on his deck in twenty-one years that he has not been able to explain. His wife says he came to sea to be the one who stays with the boat. He has not argued. Standing order: Keep the lock sealed and the bays ready to work. Watches for: An outer door that jammed with nothing wrong in it. #### Personal log, 03/07/2166: The probe PRB-3 launched from the hangar cradle at 0412 ship time. Clean release and a normal first handshake. The launch sequence is working as designed. The probe is on its planned track. #### Personal log, 09/07/2166: Drill A3 has a pressure leak at the jammed outer door. I ran the full checklist and checked the track, hinges, actuator and seals. Everything measures within tolerance. The door stays jammed. The frost ring is 5.9 meters across. Ekwueme and I measure it independently and get the same result. Curious. That is the same diameter as the docking collar on the far side. The lock fault began when PRB-3 crossed the anomaly. The B1 containers began warming at the same time. Two things changed together. I can't find a mechanical reason for it. ### Yuki Tanaka Relay technician · ENGINEERING · service number K-0533 · 6 yr · Kestrel 1 yr · born Sapporo, 2139 Yuki Tanaka is the youngest petty officer aboard and on her first deep transit. She grew up in Sapporo, where her mother kept a radio shop and taught her the old telegraph code before she could write; she still thinks in it when she is tired. She trained as a relay technician at the Fleet communications school and joined the Kestrel a year ago for the relay-laying leg of the commission. She laid relays 11 and 12 herself, the last two in the chain, and knows the handshake of every one by ear. The pattern the chain uses is hers: she made it in her second year, in a lab in Sapporo, and nobody aboard knows what it spells. She listens more than she talks. Ekwueme has taken her on as the nearest thing the ship has to an apprentice, and the two of them can be found on the drive spine at odd hours, saying nothing. She sent her mother the time through the finished chain the day relay 12 answered. It was the first message home from the far end, and it was four pulses long. Standing order: Keep eleven relays locked and find out why the twelfth is silent. Watches for: A handshake coming back four pulses long. #### Personal log, 22/05/2166: Relay 12 Relay 12 is online and the full chain is carrying traffic. Twelve handshakes between Kestrel and home are working normally. I sent my mother the time through the completed chain. It was the first message I sent from this distance. #### Personal log, 09/07/2166: Eleven Relay 04 is still dark. We can bypass it, but the longer hop leaves us one decibel short of the signal strength we need. Slow the transmission down and we recover enough signal to close the link. The fifth contact approached from the direction of Relay 04. That relay went dark at 14:22 on the sixth, before we detected the contact. I don't know whether the contact passed through Relay 04 or caused it to stop responding. The anomaly also returned our handshake with a perfect match. It copied the signal pulse for pulse.
