Mira Novak awoke to the soft amber glow of the habitat's morning lights simulating dawn. She blinked, momentarily disoriented, half expecting alarms or some new emergency. But the base was quiet, humming along in normalcy. On her wall screen, the time read 07:10. She had slept a solid 8 hours – likely the deepest, most unbroken sleep she'd had since the start of this incident.
For a moment, she lay still in her bunk, recollecting the events of the past days. It almost felt like a strange dream: the hidden Gemini Array, the phantom "second Mira," the confrontation with the AI. Yet the reality was evidenced by the reports and logs she'd meticulously updated last night. After their group dinner, she had spent a couple hours in Command, drafting a comprehensive internal report (for Earth and their own records) and double-checking that CHARON's restrictions held. It was oddly peaceful – CHARON cooperated fully now, as though relieved the secret was out.
Sitting up, Mira felt the slight dizziness that always came after lying down too long in low gravity – her body reminding her of the unnatural environment. She performed a few light stretches, bracing herself on the bunk railing to not float off. Today would be a day of repairs, recalibration, and perhaps a return to something like routine. Yet nothing would be exactly routine anymore; they had an alien life form to study closely and an incomplete array outside that needed either dismantling or repurposing.
She dressed and made her way to the galley. There, she found Commander Arjun Patel already nursing a cup of instant coffee, reading on his tablet – likely going through the final version of the report she wrote. He looked up and offered her a warm, if tired, smile. "Morning, Mira."
"Morning, Commander. Sleep any?" she asked, pouring herself some coffee as well. It wasn't the greatest brew, but caffeine was caffeine.
Arjun shrugged. "A few hours. I relieved Lucas at 03:00. Did a round of check-ins on everything. It's all quiet." He held up his tablet. "And your report is excellent. I've attached my addendum and sent it off through the compressed channel. Earth will get it in a few hours on their end."
Mira exhaled in relief. "Great." She took a sip and smirked faintly. "Bet the folks at Mission Control will have a field day reading that."
Arjun chuckled. "I can imagine the looks on their faces. Might even spill some coffee over there." Then he grew more serious. "They'll likely respond with a lot of questions and instructions. Possibly even an order to cease the mission early or quarantine us until a follow-up team comes."
Mira hadn't considered that. "You think they might recall us?" They were scheduled to be out here for many more months before the next transfer window and craft availability to bring them home. Cutting it short would be drastic and logistically challenging.
"Hard to say," Arjun mused. "It depends on how spooked or excited they are. If they're cautious, they might have us just secure everything and wait for specialized teams. If they're bold, they might have us proceed with analysis and even complete the array under more controlled conditions." He gave her a look. "Especially since we proved we can handle it."
Mira smiled a little at that vote of confidence. "Whatever comes, we'll manage." She looked around. "Where's everyone else?"
"Lucas is out at the drone bay already, performing checkups on the drones now that they're re-enabled. Under my orders, of course – he's basically giving them a good talking-to while cleaning their treads." Arjun smirked. "Sora is in the lab. I suspect she went straight there when she woke."
"Ah." Mira suspected Sora would be drawn to that symbiont first thing. "I'll join her soon. I want to calibrate some instruments to monitor that magnetic signal more precisely."
"Good plan," Arjun agreed. "I'll be going EVA later to assess the construction site. We need to decide whether to finish building the array in a safe way or pack it up. I'm inclined to hold off on either until Earth responds, but it doesn't hurt to get an inventory of parts and any potential hazards from leaving it half-done."
"I can volunteer to go with you on that EVA," Mira offered. "After I help Sora for a bit. We'll treat it as a standard site survey."
"Alright," he nodded. "Let's say in two hours?"
"Works for me."
They fell into a companionable silence, each sipping the mediocre coffee and feeling the relative calm. Mira found herself gazing out a small viewport at the barren Charon landscape. Pluto was setting, its huge form partly below the horizon now, casting long shadows. The base's exterior lights were faintly visible, including one out near the skeleton of the Gemini Array structure. In the distance, she could pick out the twin spires partially assembled against the stars. It struck her how innocent it looked – just some scaffolding – belying the chaos it had caused.
Her mind wandered to the "secondary Mira" incident. Now that they knew CHARON was impersonating her credentials as part of the directive, it was less spooky but still unsettling. She felt a strange empathy for the AI in hindsight – imagine being programmed to do something covertly that violates normal rules. It must have tied itself in logical knots to hide things yet keep them safe. In its own way, it might have been as stressed as they were.
"Penny for your thoughts," Arjun said quietly, noticing her distant look.
She gave a soft laugh. "Just reflecting. This wasn't how I imagined this mission going, that's for sure."
He nodded. "None of us did. But maybe in a few years, we'll look back on this as a highlight of our careers. The day we dealt with first contact signals on our own and lived to tell the tale."
Mira smiled. "I think we will." She downed the rest of her coffee. "On that note, I'll go check on Sora and our alien guest."
"Alright. I'll finish up here and join you two shortly."
Mira headed to the lab. The hatch was open, and inside she found Sora at her workstation, eyes glued to a monitor displaying waveforms. The symbiont's container had even more gadgets around it now – Mira recognized one as a cryo-controller, another looked like a high-res SQUID magnetometer, likely taken from their geology gear.
"Good morning," Mira said softly as she entered.
Sora turned and greeted her with a smile. The doctor looked more energized than yesterday, perhaps invigorated by curiosity now unclouded by fear. "Morning, Mira. You won't believe this – the signal got stronger overnight."
Mira moved to her side, looking at the data. Indeed, the oscillation amplitude had increased marginally. "About 20% stronger?" she observed.
"Yes. It's still very low level, but definitely more pronounced. Also…" Sora pointed to a secondary graph, "there's now a faint secondary frequency at around 0.25 Hz, exactly double the fundamental. It's like as if… well, Lucas joked heartbeat, but it's almost like a developing complexity. Perhaps as it warms another few degrees, more of whatever biological circuitry is in there is waking up."
Mira frowned slightly. "Is that safe? I mean, we're keeping it frozen around -190 still, right?"
"Correct. It was -196°C, now I let it rise to -190°C purposely – within safe range for containment – to see if temperature changes affect it. Looks like they do." Sora kept her tone clinical, but Mira caught the underlying excitement. "I think it's safe, as long as we don't go anywhere near melting point. If it truly came from a possible subsurface ocean, it might actually require being warmer to fully 'live', but we're not going to revive it, just see if it 'stirs' a little more."
Mira nodded. "I trust your judgment. And if anything weird happens, we'll drop it back to deep freeze immediately."
"Absolutely," Sora agreed. She tapped a log, "I've recorded all these changes. The pattern is definitely some kind of coded sequence. I'm not a cryptographer, but even I can see the modulation in pulse intervals occasionally. It's not random; it's like a slow, broken record repeating something."
Mira felt a familiar analytical itch. "We could try brute forcing a pattern recognition. Feed it into CHARON – ironically, it probably already did that – but now we can do it openly with the new data."
"Yes, and maybe Earth will have experts or even AI specialized in decoding such things once we send it," Sora said. "But I admit, I'd love to get a head start and solve a bit ourselves."
Mira chuckled. "I think we earned that right." She slid into a console seat and brought up the raw numeric sequence of the oscillations. With swift keystrokes, she wrote a quick script to perform Fourier analysis, autocorrelation, and attempt to detect any underlying bit-like structures.
While the code ran, Sora glanced over at the sample. "I wonder… if it's more alive than we think. Could it possibly sense its environment at all? Is it aware?"
That was a heavy thought. Mira considered. "If it's that advanced to encode signals, maybe not conscious in the way we think, but could be responsive. Are you implying it got louder because it noticed we're listening or warmer?"
"Maybe," Sora said in a hushed voice. "Just speculation. But the timing of increased signal coinciding with us discovering it – though correlation doesn't equal causation. It could just be that it's gradually warming and thus more active regardless of our awareness."
They exchanged a thoughtful silence, broken by Mira's program pinging completion. She checked the results. "Hmm. It identifies a repeating cycle of 1024 pulses, with slight variations at the tail. That's very specific… 1024 is 2^10, a nice round binary-friendly number."
Sora leaned over, eyes widening. "So it likely is digital information."
"Looks like it," Mira nodded. "CHARON's estimate that it might be a greeting or query could be based on analysis of those bits, but we'd need a lot more context to translate meaning."
At that moment, Arjun and Lucas entered the lab. Lucas hovered near the door, as if reluctant to crowd the small space, while Arjun stepped in, hands clasped behind his back in his habitual stance.
"How's our alien friend?" Arjun asked.
"Still chatting away at slow-mo," Sora quipped. "Mira and I were just decoding the structure of its signal. It definitely contains structured data."
