Three weeks had passed since Arthur first committed to the transmission array as a genuine, parallel project alongside everything else Sanctuary One demanded of him, three weeks that had felt, in retrospect, considerably longer than their actual span given how much careful, incremental progress they'd required — stolen hours here and there between the greenhouse's ongoing maintenance, the beetle population's continued expansion, and the routine, accumulated work of simply keeping an entire settlement running. He'd built the array in careful stages, exactly as he'd built everything else on this planet — the expanded power capacity first, then the antenna structure itself, fabricated from salvaged components he'd repurposed with an ingenuity he found himself, by now, almost taking for granted.

He'd fabricated the antenna's core structure from a repurposed section of the ship's original communications dish, badly damaged in the crash but salvageable enough, with considerable patient reworking, to serve this new and considerably more modest purpose. The power supply had demanded a separate expansion of the thermoelectric array's capacity, requiring him to divert a portion of the crystal stock he'd otherwise been saving for future irrigation improvements — another in a long line of trade-offs this planet seemed determined to keep asking of him, each new ambition drawing on resources some other project had claimed first.

He stood before the finished assembly this morning with a specific, cautious pride, running through GAIA's final diagnostic sequence before committing to the array's first genuine test.

"GAIA, confirm current transmission capability."

"Transmission array operational. Estimated effective range: approximately one hundred twenty kilometers under current atmospheric conditions, representing sixty percent of the distance required to reliably reach the detected signal's estimated origin point."

Sixty percent. Arthur absorbed the figure with a complicated mixture of satisfaction and frustration — three weeks of careful, dedicated work, and still short of what the project actually needed to accomplish its stated purpose. He'd known the number before GAIA confirmed it, having run the same calculation himself more than once during the array's construction, but hearing it stated plainly still carried a different weight than his own private estimate had. He'd known, going in, that a single construction phase likely wouldn't achieve the full required range, but the confirmed shortfall still landed with a specific, deflating weight after everything the array had already cost him to build.

"What would it take to close that remaining gap?"

"Further range extension would require additional antenna surface area, exceeding current material availability, or a more powerful transmission source than the array's current power supply provides. Estimated additional development time: two to three weeks, contingent on locating suitable supplementary material."

Two to three more weeks. Arthur turned the estimate over, weighing it against the specific, growing urgency that had built alongside every signal detection over the preceding days — the amplitude increase he'd first noticed the night of the greenhouse's completion, subsequent readings that had continued showing gradual, incremental strengthening, and GAIA's increasingly confident, though still carefully hedged, assessment that the source was likely drawing measurably closer rather than simply transmitting with improved clarity.

"How much has the signal actually strengthened, cumulative, since we started tracking it?"

"Cumulative signal strength has increased by approximately three hundred percent since initial detection three weeks ago. Current trend, if extrapolated linearly, suggests the source may be approaching a distance within reliable detection range of our current transmission capability within the next several days, though this extrapolation carries considerable uncertainty."

Arthur sat with the projection a long moment, feeling the specific tension between GAIA's careful scientific hedging and the plain, human urgency the underlying trend suggested. He'd noticed the pattern himself over the preceding days, watching each night's reading climb steadily past the last, and had told himself, each time, not to read too much into a single data point — advice he found considerably harder to follow now that the accumulated trend across three full weeks left less room for alternative explanation. Whatever was out there, moving closer at whatever pace and for whatever reason, might be within reach of his current, imperfect transmission capability within days — considerably sooner than the two to three weeks a properly completed, full-range array would require.

"If I transmit now, at sixty percent range, what's the actual probability it gets received?"

"Current probability estimate: moderate, contingent heavily on the source's own receiving sensitivity and its actual current distance, both of which remain unconfirmed. A more powerful array would substantially improve this probability. However, given the observed trend toward decreasing distance, current capability may prove sufficient within a narrowing window."

Moderate. Not the confident, high-probability outcome a fully completed array might have offered, but not negligible either — a genuine, uncertain chance, weighed against a delay that might allow the signal's source to pass beyond whatever window of proximity currently existed, if the underlying trend didn't simply continue indefinitely in his favor. Arthur turned the word over several times, testing it against every risk calculation two months of survival on this planet had taught him to run instinctively by now.

Arthur walked the short distance from the array to the small table he'd built weeks earlier, its two chairs standing exactly as they had since the evening of his first real harvest, and sat there a long while, turning the decision over with the same careful weighing he'd applied to nearly every significant choice since the crash — the caution that had kept him alive through countless earlier crises, set against a hope he'd been quietly, deliberately cultivating for weeks now, unwilling to let either pure recklessness or excessive caution make this particular decision for him without his full, deliberate consent.

He ran his fingers along the table's edge as he thought, a habit he'd developed without quite noticing when it started, and found himself, for perhaps the first time, genuinely grateful for the two-chair design's persistent, quiet presence in his daily routine — a physical reminder, sitting right in front of him, of exactly what he stood to gain if this particular gamble actually paid off.

"GAIA, if I wait for the full-range array, what's the actual cost of that delay? Best case and worst case."

"Best case: two to three weeks additional construction results in a considerably more reliable transmission capability, improving success probability substantially regardless of the source's exact position at that time. Worst case: the source continues its apparent approach and either passes beyond effective range before the improved array completes, or changes course entirely, rendering the delay's benefit moot."

Arthur turned the two scenarios over, recognizing in them the same fundamental uncertainty that had defined nearly every significant decision on this planet — no perfect information available, only careful weighing of probable outcomes against the specific cost of waiting versus acting. He thought, sitting there at his two-chair table, of every time in his old life he'd let caution and the pursuit of a more perfect, more certain outcome cost him a window that mattered — the promotion he'd delayed pursuing until someone else claimed it first, the reconciliation with his sister he'd kept postponing until pride made it considerably harder than it needed to be, the conversation with Mira he'd told himself he'd have once he'd found exactly the right words, right up until there was no longer any opportunity left to have it at all. Each of those missed windows had felt, at the time, like the responsible, careful choice. In hindsight, every single one of them had simply been fear wearing caution's more respectable clothing.

He stood from the table finally, the decision settled in a way that felt considerably more solid than the uncertain variables underlying it might have justified. He made his decision with a clarity that surprised him, given how genuinely uncertain the actual variables remained.

"We transmit now. Sixty percent range, moderate probability, whatever the current array can actually manage. I'm not waiting three weeks for a perfect signal and risking it passing us by entirely." He said it aloud, deliberately, wanting to hear the decision spoken rather than simply settled in his own head.

"Acknowledged. Preparing transmission sequence. Recommend a simple, clearly structured signal — mathematical constants, prime number sequences, or similarly unambiguous patterns that would be recognizable as artificial and intentional regardless of the receiving party's specific technology or language."

Arthur spent the remainder of that morning working with GAIA to construct exactly such a signal, a careful, deliberate sequence built from patterns any technologically capable receiver should, in principle, recognize as evidence of intentional, artificial origin rather than natural noise — the same logic, he reflected, that had first convinced him the signal he'd been tracking wasn't simply atmospheric interference, now applied in reverse, crafting something equally unmistakable to send back.

He found the composition process oddly moving, more so than the purely mathematical content might have suggested it should be. Every prime number and constant GAIA encoded into the sequence carried, beneath its clinical precision, the same simple message he couldn't quite bring himself to encode more directly: someone is here, and they noticed you, and they wanted you to know it. He supposed that was, in the end, the only message that actually mattered in a first transmission like this one — everything else could wait for whatever conversation, if any, eventually followed.

By early afternoon, with the transmission sequence finalized and the array's next available window approaching, Arthur found himself standing before the assembly with a nervousness he hadn't quite anticipated, given how many considerably more physically dangerous moments this planet had already put him through. This felt different — not a risk to his own survival, but a genuine, vulnerable act of reaching outward, extending something of himself toward an uncertainty he had no way of controlling the response to, if a response came at all. He recognized the particular quality of the nervousness, once he named it honestly to himself: it felt less like the practiced calm of engineering risk assessment and considerably more like the specific, exposed vulnerability of confessing something to another person for the first time.

"GAIA, transmission window opens in five minutes," he said, more to steady his own nerves than because he needed the reminder.

Arthur used the interval to walk a slow circuit of the array, checking connections one final time not because he expected to find anything wrong, but because the physical activity gave his restless hands something to do besides simply waiting. He found himself, more than once during those five minutes, catching his own breath held longer than necessary, a small physical tell of nervousness he hadn't experienced with quite this specific flavor since long before the crash. He thought, standing there in the strengthening afternoon light, of every time he'd hesitated before saying something that actually mattered to another person, weighing the words too carefully, waiting for a more perfect moment that had, more often than he wanted to admit, simply never arrived. He thought of Mira, of every conversation he'd postponed until postponing had become its own kind of answer, an answer he'd never actually intended to give.

He checked the clock once more, the final minute counting down toward the transmission window's open. He was not going to make that particular mistake with this. Whatever was out there, whatever the actual odds of it hearing him, he intended to have at least tried to say something rather than let caution's endless refinement cost him the window entirely, whatever the outcome turned out to be.

"GAIA, transmission window open. Send it."

"Transmitting."

The confirmation carried no particular drama, no dramatic hum of power or visible change in the array's quiet operation, simply GAIA's flat, factual confirmation that the careful sequence he'd spent the morning constructing was now, in whatever form radio waves actually took, moving outward across the two hundred kilometers separating Sanctuary One from wherever its intended recipient currently stood. There was something almost anticlimactic in the silence of it, Arthur thought — no visible beam, no audible hum, nothing to mark the moment beyond a small, steady readout confirming output within expected parameters, as though the universe itself had decided this particular milestone deserved no more fanfare than any other routine system check. Arthur stood before the array for the full duration of the transmission window, watching the readout confirm steady, uninterrupted output, and felt, once it finally concluded, a specific mixture of relief and renewed, sharpened uncertainty.

"Transmission complete. Full sequence delivered without interruption."

"And now we wait."

"Correct. Recommend continued monitoring of the established signal window for any change in the source's transmission pattern that might indicate receipt and response, while maintaining current development priorities in the interim."

Arthur nodded, absorbing the recommendation's characteristic, sound caution, and made his way back toward the greenhouse to check on the Starfall Baobab's continued germination progress, forcing himself back into the day's other necessary work rather than simply standing at the array, willing a response into existence through sheer, anxious attention.

The greenhouse offered its own small, welcome distraction — three sprouts now visible in the carefully stabilized soil, their pale, curled shapes pushing up through ground he'd tended with two months of accumulated expertise, a small, tangible proof that patient cultivation continued its own steady work regardless of whatever uncertainty hung over the signal he'd just sent outward. He knelt beside them a while, grateful for something immediate and concrete to focus his attention on rather than the diffuse, unanswerable question now hanging over the northeastern horizon. He spent an hour on routine maintenance, checking humidity levels and confirming the ventilation modification's continued effectiveness, before finally allowing himself to return to the array for one more check before evening settled in fully.

"GAIA, any change in the signal pattern since transmission?"

"No change detected. Signal recurred at the established interval, with amplitude consistent with the most recent readings. No indication of response to today's transmission."

No immediate response. Arthur absorbed the confirmation without the sharp disappointment he might have expected, recognizing, even in this first uncertain hour, that a response — if one came at all — would likely require time to travel, to be composed, to make its own journey back across whatever distance still separated Sanctuary One from wherever the signal originated. He reminded himself, standing there, of every other patient wait this planet had already taught him to weather — the seeds that took days to show any sign of germination, the storm that had to run its own course regardless of his impatience — and made a deliberate effort to extend that same hard-won patience toward this considerably more personal uncertainty. He'd sent something outward today, deliberately and with full knowledge of the uncertainty involved, and that act itself, regardless of whether an answer ever actually arrived, felt like its own kind of accomplishment.

He opened his personal log that evening with a specific steadiness he hadn't quite managed in the anxious hours since the transmission.

*Sent our first signal today. Sixty percent range, moderate odds, no guarantee it even reaches whatever's out there, let alone gets understood or answered. I decided not to wait for the perfect version of this project, the one that would take three more weeks to build and might miss the window entirely.*

*I keep thinking about every time in my old life I waited for perfect conditions before saying something that actually mattered — waited for the right moment with Mira, the right opening with my sister, the right circumstances that never quite arrived because I kept holding out for certainty instead of just speaking while the chance was actually in front of me. I'm done doing that. Whatever this signal turns out to be, whoever or whatever eventually answers it, I wanted to make sure I'd actually tried rather than let my own caution cost me the chance to find out.*

*There's a version of me, two months ago, who would have spent the full three weeks perfecting this array before ever risking a transmission, terrified of sending something imperfect out into the unknown. I understand that impulse. I don't think it actually serves me anymore. Perfect and silent has never once, in my whole life, been better than imperfect and honest.*

*No response yet. I don't expect one immediately. But I sent something real out into the dark today, deliberately, with my eyes open about the risk of silence coming back instead. I think that's worth something on its own, regardless of what comes next.*

He closed the file and stepped outside one final time before settling in for the night, looking out toward the northeast horizon where the array now stood ready for its next transmission window, and found himself, despite the day's genuine uncertainty, settling into sleep with a specific, hard-won peace — the particular calm of a man who had finally acted on a hope rather than merely holding it, and could now simply wait to see what that action actually brought back to him.

He thought, drifting toward sleep, that whatever tomorrow brought — silence, continuing uncertainty, or something else entirely — he would meet it having already done the one thing he most regretted never doing in every relationship he'd let slip away before this planet forced him to finally learn better. He had spoken first. Whatever came next was, for once, not a question of his own courage but simply of what waited to answer it.

GAIA Protocol — Current Readouts Biomass Index: 3.5% Oxygen density: 0.4% Air humidity: 0.9% Subzone: Sanctuary One — Level 2.0 (Transmission array operational at sixty percent effective range; first outbound signal sent — no response detected as of this reading)

Somewhere across the two hundred kilometers separating Sanctuary One from whatever waited beyond it, a deliberate, careful signal now traveled outward into the gathering dark, carrying with it two months of patient hope from a man who had finally decided that trying mattered more than waiting for certainty that might never actually arrive.

Tomorrow would bring whatever it brought. Tonight, Arthur Vance slept more soundly than he had in weeks, the particular rest of a man who had finally stopped merely preparing to reach out, and had actually reached.
