Stopping the moving dot did not stop the home.

Darae paused the automatic display. The timestamp beneath it, recording the last actual observation, stayed unchanged. Catalog explained that it had updated a predicted position, not received fresh sensor data. The intake screen had not gone out into space and watched the missing hours.

It was the evening twelve days after the first rescue. After the Safety Office’s short reply, she contacted its duty officer. All twenty-three residents were at Raon. Neither the five main modules nor S-6 held anyone. First she needed to distinguish what kind of danger had arisen.

“Has a collision been confirmed?”

“No. We’re recalculating prediction uncertainty because of a tracking gap.”

That did not confirm that everything was unharmed, either. Darae deleted EMERGENCY EVACUATION from her proposed resident notice. There was no report of danger to their present living space at Raon.

The briefing was beside the north port. Mujin had arrived first to check scheduled flight material. An observation officer opened two sets of data in different colors. Main habitat and S-6 had moved differently since the rescue; they could not become one dot today.

A little over four hours had passed since the last accepted observation. One scheduled observation had overlapped the bright edge of Earth, preventing adequate identification. A measurement from another route had arrived, but review had not established which object it showed. It had not been used to confirm a new position.

“So there’s data that didn’t arrive, and data that arrived but we can’t use.”

“Yes. Neither turns a predicted point into a new observation.”

Smooth movement on the screen came from calculation. It was no fresh confirmation that the object occupied that exact place. Through an observation gap, position and velocity errors could grow in subsequent predictions.

Darae looked outside. A light as small as a star passed the window. Seeing it did not establish Sai’s position. Giving a visible speck the name of your own possession was surprisingly easy.

The officer displayed an elongated region around the main habitat’s predicted path. A possible close passage overlapped another object’s predicted region. Lines crossing on a drawing did not alone mean collision: positions at the same time, their uncertainties and observation quality mattered together.

“Could it have gone farther while we weren’t looking?”

“We need to narrow the possible range again. I won’t give the risk as one precise number from the current material.”

The officer wrote neither SAFE NOW nor COLLISION IMMINENT. The need for further observation was clear. The existing review of a voyage for external inspection of the unoccupied facility again carried a condition: current tracking data.

Mujin folded his flight schedule.

“We won’t follow this prediction alone. After new observations, we’ll match the approach target and abort conditions to them.”

He did not offer to shorten Narae’s preparations and give chase. Return fuel could not make up for an observation gap. Darae asked whether the lost-and-found office must suspend all work while Safety filled it. The duty officer asked her to maintain preserved property and resident support.

Work inside Raon continued while steps toward Sai slowed. She confirmed the handover for her own duty staff. Faulty 7-B, original card and packaging remained under emergency preservation, without a restarted deadline. S-6’s three support items remained at their unoccupied locations. The second sound candidate and coolant pump stayed in specialist maintenance storage at Raon. An uncertain position was no reason to move property arbitrarily.

During the briefing, one measurement under identification review was ruled unsuitable. It was more likely to belong to a neighboring object and would not enter this update. The uncertainty region widened. New information could leave a prediction less precise when unsuitable data was properly excluded.

“Has it disappeared?” Darae asked.

The officer shook their head.

“We have the last actual observation and the current prediction. We have not accepted this particular measurement as a new observation of the target.”

Her question had been too large. A box briefly hidden beyond a shelf did not receive a LOST stamp. Yet she had quickly attached disappearance to the home outside.

The next independent observation opportunity was arranged within available time on the existing network. Nobody created a new sensor on the spot. Another route and responsible officer were assigned if the first failed. Residents were not expected to stay up all night making both produce results.

Before contacting Haeseong, Darae checked what could be shared. Residents needed the uncertainty affecting a possible home, without another object’s entire flight data. Safety supplied a relevant summary and the time of the next status notice.

Haeseong received her call in the habitation ring’s common space. He still distinguished his own opinion from everybody’s answer.

“Does this mean we can’t recover what we left inside?”

“Approach is currently unapproved. Destruction of the property hasn’t been confirmed. More tracking data is being sought.”

He asked for the notice to reach residents who wanted it through their chosen individual routes. He did not suggest sparing relocation applicants needless worry. People leaving also had possessions inside.

The woman with the leaf container checked her cooking-support inquiry. Darae read its entry aloud: a continuing personal-property preservation request, without a promised retrieval voyage.

“I’m not asking you to fetch it now. Don’t go into danger for my pots. But don’t tell me later that it wasn’t mine.”

Darae kept both statements. Concern about flight safety was not abandonment of property rights. One consent obtained from a representative could not shorten a person’s longer answer.

Returning from Safety, Mujin checked the preparation line at the north port. Narae’s work lights were on; no departure signal showed. A maintenance worker passed with a fuel checklist. Darae moved out of the passage.

“From outside, it looks like a ship just waiting.”

“There’s work while we decide not to go. We just don’t record it as having gone.”

He handed his preparation sheet to its custodian and changed shift. The plan was not for one person to endure the same chair until an observation reply arrived.

While he finished, Darae edited the notice in the port rest area. A transport worker by the window saw the elongated region and asked whether a large new cargo rack had been attached. She explained that it showed position uncertainty, not the home’s physical shape.

Residents might read the picture the same way. Before sending it, she checked the legend with Safety. The officer supplied an existing explanatory diagram distinguishing the main habitat’s outline from its uncertainty region. She sent the legend too, instead of a cropped screen. An easy picture did not acquire an accurate meaning by itself.

Her meal pouch sat halfway inside a restraint pocket. Near the axis, a hand accustomed to weak weight could release the contents while opening it. She secured tray and body, then loosened the lid. A cold vegetable fragment caught at the opening. Reaching hastily made her body turn slightly out of the seat.

She shortened her restraint and caught the fragment. When the three-knock call sounded, she closed the pouch first. It was an ordinary office inquiry, not Safety’s emergency alarm. Dropping everything for every sound could lose the thing immediately before her.

“You need to eat today to check things tomorrow,” Mujin said opposite her.

“No observation, so I’d apparently settled for predicting dinner too.”

They laughed and finished eating. A long wait was no reason to leave the evening of people living at Raon blank as well.

Back at the office, the owner of a small tool received that afternoon was waiting. Darae pushed the moving dot out of her thoughts. He described the white mark on its handle. She compared two candidates and confirmed physical receipt. Something seen today could have today’s observed location and actual recipient recorded.

She linked Safety’s notice to Catalog’s prediction display. Beside AUTOMATIC POSITION, last actual observation and prediction update now appeared on separate lines. This was a work setting reducing misreading, without expanding the software’s abilities or giving it an observation function of its own.

At shift change, she explained that the next status notice would arrive at night. The incoming worker opened the contact sheet. Maru’s name remained under SAI COMMUNICATIONS, copied from the rescue’s old sheet into the follow-up form.

Everyone knew Maru was now at Raon. Yet a symbol beside the name still meant CONTINUOUSLY AVAILABLE, as though the apprentice should interpret and relay professional observation notices through the night.

“Connect tonight’s reception to Safety’s adult duty officer. Resident notices go through the support staff’s established route.”

The worker changed the actual recipient and obtained acknowledgment. No call asked Maru’s guardian to take over night work. Maru’s personal inquiry route remained. Removing a name from a roster did not remove that person’s right to speak.

Safety’s night notice reconfirmed the next observation booking and the absence of an accepted update. No new position had yet been confirmed, and no additional action was required from people at Raon. Darae told her successor that today’s blank remained blank. Waiting for an answer did not make it complete.

As she prepared to leave, Maru sent a message through the guardian: would calls stop arriving under that name tonight? When Darae said yes, a photograph followed of the old communications notebook. Beneath NIGHT, small handwriting crowded a rectangle.

I could read it fastest.

Darae stopped before praising such diligence. A child who read quickly and a child required to read every night were different facts.

She added the old contact sheet to preparations for tomorrow’s shared-duty meeting. Professionals had to narrow the unobserved hours. The nights of those waiting through them could not be filled with one young person’s name.
