Chapter 1: Descent
I brace myself against the acceleration couch as Aegis—our lander’s AI—announces in a calm, female voice: “Altitude 1200 meters. Descent nominal.” My heart pounds in my ears. Through the small window above my seat, I see nothing but orange haze. We’re plunging blindly through Titan’s thick atmosphere, trusting radar and Aegis to guide us to a safe landing.
“Thrusters online… parachute release in three, two, one—” comes the AI’s voice. A sudden jolt snaps us against our harnesses as the drogues deploy. I grip the armrests. Across from me, Commander Raj Patel breathes steadily, eyes on his console. To my right, Jack Nguyen—pilot and engineer—murmurs, “Easy girl, easy,” as if soothing the lander. Valentina Benitez, our mission specialist, mouths a silent prayer. I’m Mira Alonzo, astrobiologist. Which is a fancy word for alien biologist. 
I catch Jack’s gaze and force a grin. “Still with us?” I quip. My voice trembles despite my attempt at humor. After seven years in transit, we’re finally here—Saturn’s largest moon. As an astrobiologist, I’ve dreamed of this moment since I was a kid devouring stories of alien worlds. Now I’m about to become the first human to set foot on Titan. Assuming we land and not splat.
“Main chute deployed. Descent rate 8 meters per second,” Aegis reports. The turbulence, or buffeting as the crew calls it, eases as the main parachute takes hold in Titan’s dense air. We’re descending slower now, drifting like a seed through a caramel sky. Outside, the haze thins slightly. I press my helmet to the window and catch a glimpse below: a dim, dusky landscape, tones of rust and brown. It looks flat—good. At least we won’t land on a boulder or in a methane sea. I exhale slowly.
“Hundred meters,” Jack calls, hands hovering over manual thruster controls in case Aegis needs help. My stomach does a somersault as we break through the last cloud layer. Titan’s surface appears in surreal clarity: an alien plain under an orange twilight. I see what might be rocks—rounded, dark shapes—and patches of lighter ground. A small lake glitters off to our left like a patch of ink. My breath catches. Lakes of liquid methane… It’s beautiful and terrifying.
“Touchdown in five… four…” Aegis continues. A slight crosswind rattles us; the AI fires a side thruster to compensate. I feel a final downward lurch. “…three… two…” Thump! The whole cabin shudders, then stills.
Silence. For a moment, none of us moves or speaks. Aegis breaks the hush: “Touchdown confirmed. Welcome to Titan.”
A laugh bubbles out of me, half joy and half relief. “We made it,” I whisper. Over the radio, I hear Mission Control clapping—except that’s just memory. There is no live cheering from Earth; they won’t even get our signal for over an hour. Right now it’s just us, alone on this frozen world.
Commander Patel unstraps and stands gingerly in the low gravity, a broad smile breaking through his stoic mask. “Alright, team,” he says, voice crackling with emotion, “Landing sequence complete. Let’s secure the lander and prepare for EVA.”
Jack whoops quietly as he and Valentina exchange a fist bump in microgravity slow-motion. I feel weightless—partly from Titan’s weak gravity (only one-seventh of Earth’s), but mostly from exhilaration.
Unbuckling, I float up slightly and then plant my boots on the deck. Everything in the cabin seems to move in slow, graceful arcs. A stray pen that escaped its Velcro tether drifts by my head. Titan’s gravity is so low, yet its thick atmosphere provides a gentle drag. It feels like I’m underwater and airborne at the same time.
“Careful,” Jack warns with a grin as Valentina nearly launches herself into the ceiling by pushing off too hard. “Gravity’s about 0.14g—don’t go jumping around just yet.”
Valentina chuckles, excitement evident on her face. “I can’t believe it. We’re actually here!” She peers through a porthole. “¡Dios mío! Look at that sky.”
I join her at the window. Outside, a faint light filters through orange smog. It’s like late afternoon on Earth after a dust storm, dim and coppery. In the distance Saturn’s enormous silhouette looms as a darker patch in the sky, but the haze hides its rings. The ground directly below our lander looks yielding, maybe a mix of ice grains and hydrocarbon sand. There’s no sign of movement—no aliens waving hello, just an eerily still landscape.
Commander Patel’s voice comes through my helmet earphones. “Mira, run the post-landing diagnostics with Aegis. Jack, begin power transfer from descent batteries to the reactor. Valentina, prep the EVA suits.”
“Roger that,” we chime almost in unison. I head to the console and tap the screen. “Aegis, give me a status report.”
“All systems stable, Dr. Alonzo,” the AI responds. “External temperature: -178 degrees Celsius. Surface pressure: 1.45 atmospheres. Wind speed: 4 kilometers per hour from the east. Lander integrity holding at 100%.”
She—the AI’s voice module has a pleasantly wry tone—continues with a checklist of data. I scan the numbers, feeling a giddy satisfaction. Those figures match what we expected from decades of remote measurements. Still, seeing them here, now, on my screen, means our new home is real. Harsh, cold, but real.
“Telemetry looks good,” I report. “We’re sitting pretty on level ground. No significant tilt.”
“Radiothermal generator is active, reactor start-up in progress,” Jack adds. He’s flipping switches above his head. “We’ll have full power and heat soon.”
“Good. Let’s hope the heater keeps our butts warm out there,” Valentina says from behind, wrestling a suit pack out of storage. “It’s colder than my ex’s heart on this moon.”
I snort a laugh. Trust Valentina to crack a joke about her divorce minutes after landing on an alien world. Commander Patel even chuckles quietly. The tension of descent is melting into excitement.
Jack pats the control panel affectionately. “And good girl, Aegis. You stuck the landing.”
“I aim to please,” the AI responds. Is it my imagination, or does she sound smug?
Patel claps Jack on the shoulder. “Great piloting as backup, Mr. Nguyen.”
Jack shakes his head. “All Aegis. I just watched.”
“Record shows you were prepared to take over if needed,” Aegis counters primly. “Though I appreciate the compliment.”
The banter between Jack and the AI makes me smile. Early in the journey, he spent long hours fine-tuning Aegis’s landing algorithms with her. They’ve become a bit like an old married couple—ironic, since one of them isn’t human.
I float toward the small airlock where Valentina is lining up our Titan EVA suits. They’re bulky outfits, cobalt-blue in color to stand out against Titan’s orange backdrop. Unlike Moon or Mars suits, these aren’t pressurized like a balloon—Titan’s air pressure is actually higher than Earth’s. Instead, the suits are heavily insulated and sealed against the toxic hydrocarbons. Each has an integrated backpack life support system and a full-face helmet with a heated visor to prevent fogging or frosting. They look cumbersome, but without needing high pressure, they’re a bit more flexible than the ones we used on the Moon.
Valentina catches me admiring the gear. “Ready for a stroll, Mira?” she asks, eyes gleaming. We’ve done countless practice EVAs in simulators and vacuum chambers, but this will be the real deal.
I nod, feeling a childlike grin stretch across my face. “Let’s suit up.”
My hands tremble slightly as I help him lay out the suits. Outside, through the hull, Titan beckons. In minutes, I’ll be stepping into that alien sand. A shiver of anticipation runs through me. Titan’s surface… I wonder what we’ll find?
I glance at the others. Jack and Commander Patel are double-checking instruments one last time. Valentina is humming a Spanish tune under her breath—probably to calm her nerves. I realize I’m holding mine.
Exhaling, I flip on my suit’s internal radio. “This is Dr. Mira Alonzo, preparing for the first human EVA on Titan,” I say softly, mostly for the historic thrill of it. My voice echoes in my helmet. “Wish me luck.”
“You’ll do great, Mira,” Aegis replies gently in my earpiece. “All vitals are green.”
Patel gives me a thumbs-up across the cabin. Jack offers a playful salute. And with that, I climb into the airlock, heart pounding with excitement for what lies beyond the hatch.
