Aether’s communications system returns to operation through Sully and Thebes’s painstaking calibration of a replacement dish, bringing a long stretch of silence to an end. The first recovered signal is telemetry from the probe on Europa: proof that the repair has restored a working link, and that the crew’s costly spacewalks accomplished their purpose, even as they continue to wait for a call from home.

The outage and the repair

Aether’s main communications dish broke away while Sully was scanning for signs of Earth. After a cacophonous bang, the comm. pod fell silent; when Sully rebooted its machines and checked their connections and stored telemetry, everything aboard the pod appeared normal. The failure was outside the pod: she saw the dish drift away from the ship. The equipment’s sudden absence made communication infrastructure visible as a fragile chain of hardware and labor rather than a dependable background service.

Replacing the dish required spacewalks. During the work, Devi’s suit scrubber failed because its lithium hydroxide cartridge had failed, and she died before she could return to the airlock. Sully remained outside to finish installing the bolts and get back to the ship. The communications repair was therefore bound to a profound loss: the new system would serve its purpose, but only after the crew had paid for it with Devi’s life.

Bringing the system back online

For Sully, work on the replacement system offered a narrow refuge from grief. She and Thebes spent the morning in the comm. pod, concentrating on the task rather than discussing the spacewalk. Sully feared that a gesture of sympathy might send her back into hiding and the repeated memory of Devi drifting away; fixing the communications system was what she could manage.

That afternoon, a week after the original dish broke away, the crew received their first signal. It was telemetry from their probe on Europa. Sully checked her machines one by one, confirming that they were receiving properly and saving the incoming data to the hard drive. The recovered signal showed that the spacewalks had achieved their directive: the effort had yielded something beyond the loss itself.

Calibration and what the signal means

The first reception was only a beginning. Sully and Thebes tested the new system, adjusted gain, and tinkered with squelch settings. The signal gradually became clearer and its feedback softer. By the end of the day they had calibrated the equipment as well as they could; its reception was as good as it would ever be. If anyone was trying to call Aether, the crew had made it possible to hear them.

The recovered Europa telemetry was not a message from Earth, nor did it resolve the crew’s uncertainty about what awaited them. Sully stayed after Thebes left, listening despite recognizing that there was nothing out there to connect to yet. Still, having done their part made her feel less alone. She could no longer make the silence her responsibility: the system was ready, and the next signal, if one came, was beyond her control.

Grief alongside restored function

The technical recovery did not erase the loss that accompanied it. Sully continued to remember her grip on the dish mast and the helplessness of being unable to prevent Devi’s death. She also wondered whether Devi had noticed the falling oxygen levels and chosen not to say anything, a question she knew she would never be able to answer.

Earlier, Sully had withdrawn from her crewmates, answering their visits with the promise of tomorrow because she could not face that day. The work of restoration brought her back into the shared mission, while Thebes’s quiet presence let her focus without requiring her to explain her grief. Aether’s communications system was operational again, but its return mattered for more than the technical link: it gave the crew a prepared channel through which a distant voice might reach them, without pretending that hope was the same as contact.
