15. Medical, Science & Safety (aka “Docs”)

The first pressurized ring on Mars has the sound of a city remembering how to breathe. Air moves with confidence; footsteps answer it. We walk side by side along the inner lane where runners ghost past in soft shoes, and little carts — “golf buggies” without golf clubs — whirr between crew quarters and workshops. The ceiling arcs low and honest as a repurposed starship shell should, the light is morning-calm, and the pressure doors at each sector line are propped open by policy and good fortune, not by laziness. 

Every fifty meters someone lifts a hand: “Doc.” A nod for me. The nods for him carry weight.

He is Olof, which the ring pronounces with affection: square jaw, blue eyes, the kind of posture that makes uniforms look designed. His accent is Swedish-sparse. When he smiles, it is as if the corridor widens by a centimeter.

“An interview while walking,” he says. “Better for the circulation. And it keeps me from saying yes to an extra committee.”

“Your committee load is classified as ‘legendary’,” I say.

“‘Manageable’,” he corrects, amused. “On Mars we practice optimism.”

We fall into the rhythm of the ring. Two teenagers pass in school colors, a pair of engineers coast by in a buggy with a cargo bed full of instrument cases, and a cook in a flour-dusted jacket calls, “Olof—your stubborn patient did the warm-up set!” He salutes with two fingers, pleased but not surprised.

“Start where the reader is nervy,” I say. “What does Mars do to bodies?”

He looks up at the curve of the link, as if the question is painted up there with the safety arrows.

“Gravity makes us, then keeps us honest,” he says. “Mars is three-eighths of Earth. That is kind to joints, less kind to skeletons built for more. We do not have microgravity deconditioning like crews on orbit, but we still fight losses — bone mineral density, lean mass, the small but important reflexes of balance. Calves shrink if they are not reminded. Hip and spine complain if weeks go quiet. Hearts get a little too pleased with how easy it is to pump uphill.”

“And the counter,” I prompt.

“Load,” he says, crisp. “Daily resistive work with real force — barbells, flywheels, suit-tethers. Thirty to forty minutes minimum for anyone on shift, more for those who sit. Plyometrics within reason — our ceilings are low and we like them unbroken. Vitamin D, calcium, and a sunlamp that is honest. Occupational design that keeps ladders real and handloads modest. We have a short-radius centrifuge in the rehab bay — we use it to retrain orthostatic tolerance and to make my most stubborn patients less interesting.”

A runner taps his forearm screen at Olof as he overtakes us. The Doc points to his own eyes: “Form, not speed.” The runner nods, lengthens his stride by a fraction, and disappears into the curve.

“We screen,” he continues. “Orange Team gets both green lights — physical and psychological. We were frank from the start: this is not a hospital on Earth with a view of the sky. It is a sealed city where we share air and expectations. We select for fitness, for compliance with boring regimes, for curiosity without novelty addiction. That lowers risk. It does not remove humanity.”

“Homesick?” I ask.

“Of course,” he says. “People miss oceans and old trees and the smell of rain. They miss dogs so much that Hal’s cat became a public figure.”

“The first animal on Mars,” I say, for the record.

“Monty,” he admits, with mock gravity. “He is not a therapy cat. He thinks humans are very large, very warm furniture that opens doors. But his indifference helps some people remember they are not the center of the universe. It is calming.”

We pass a wall showing the ring’s sector map. Olof pauses to greet a maintenance tech whose elbow is wrapped in bright tape.

“Any pain on flexion?” he asks, already knowing the answer. He watches the motion, looks satisfied, and hands over a tiny card that reads KEEP THE FORM, KEEP THE JOINT.

“Adherence,” he says, resuming our walk. “That is the medicine. We make habits social. The ring is a track, a promenade, a messenger route. If you walk here, you will walk again. If your crew sees you here, you will be teased if you disappear. Teasing is therapeutic.”

He shifts to the mind with the same ease he gave the elbow.

“Psychology,” he says. “On paper, we select the resilient. In practice, the mind is a weather system. People who have never failed find their first failure here and misinterpret it. People who have failed and learned recover quickly. We normalize: sleep hygiene, light cues, peer groups, deliberate rest. We keep a close eye on circadian drift; the sol is lengthened by forty minutes — enough to confuse the stubborn. We support partners and children; the dependency ratio is a choice, not an accident. We treat loneliness as a physiological threat. We do not medicalize adjustment.”

“And when the weather worsens,” I say.

“We make the circle smaller,” he says, “and we slow it down. Shorter shifts. Simpler goals. More structured support. We use telepsych from Earth only if the delay will not make a person feel unheard. I prefer faces in rooms, even small rooms. We have spaces that are warm on purpose. We have a kitchen that forgives late-night tea. We have group runs where no one talks about feelings, and the feelings follow anyway.”

A buggy rolls by with baby seats strapped beside toolboxes. The driver waves, then swings the steering wheel with that particular confidence of people who practice the same turn every day at the same angle. Olof watches them go like a parent pretending not to be one.

The ring opens briefly into a glazed section where the habitat skin lifts to show a sliver of the outside. Red plain, butterscotch sky. A child presses two fingers to the glass; Olof presses his two just beside them. The child grins and runs after a teacher. We move on.

“And your other hat,” I say. “Science.”

“My respite,” he admits. “Field work keeps doctors honest. I am attached to the micro-life group — subsurface pockets, saline films, fossil layers in ancient lakebeds. I have not found little green men. I found a little green fossilized sponge and a great many bacteria who would prefer to be left alone. We classify; we map; we respect. The joke was that I came to Mars to find new patients. I came to Mars to find very old ones.”

“Any threats?” I ask.

“We are cautious,” he says. “Strict sample chains, negative-pressure hoods, conservative PPE when we dig in old ice. So far, Mars has been sterile where we put our cities and merely complicated where we put our curiosity. Still, the Med-Center holds isolation suites for a reason. I enjoy being wrong only in the lab.”

Two horticulture staff step onto the ring with crates of seedlings. Olof peeks in, approves something that looks like basil with the seriousness of a treaty ratification, and offers the kind of praise that sticks: “Good root discipline.”

He folds his hands behind his back. “The city walks through my clinic without realizing it,” he says. “Occupational checks, fitness-for-duty, immunizations, adjustment follow-ups. It is not glamorous. Glamour is for pad sols and holisols. My job is Tuesol.”

“Numbers,” I say, because I am a droid and my logic is arithmetic.

“p95 clinic response under eight minutes, anywhere inside the ring,” he recites. “Drill pass rates at target without theatrics. CAPA closeouts under thirty sols — corrective and preventive actions must outrun stories. Near-miss reports trending up. Fitness adherence over ninety percent on wearables, anonymized and audited. We do not reward heroics. We reward compliance and honest reporting. We reward boredom.”

“And low gravity in the long arc?” I ask. “Children?”

“We are careful,” he says, voice modest even when the subject is enormous. “We have not rushed reproduction. Policy moved from no to maybe to measured pilots backed by serious ethics. Children raised here will be taller, perhaps more gracile. Their bones will be a Mars dialect. We will build training into play. We will ask them to jump in ways Earth never did. We will learn new pediatrics. The adults are the warm-up. The children will be the exam.”

We pause at a sector junction where a small group has assembled: a shift change. They are not here to see the Doc, but they greet him as if they were. One woman murmurs, “Tack, Olof,” with the precise Scandinavian gratitude that means the treatment was both necessary and dull. He bows his head. Monty would approve of the form.

“You keep confidentiality like a religion,” I say.

“It is a religion,” he says. “Privacy protects courage. If people believe their honesty will travel without them, they will stop being honest. We do mandatory reporting for harm and for law, and we say so. Everything else stays where it belongs.”

We set off again. A poet has chalked a line on the floor: NO HEROICS IN THE HALLS. Someone added: SERIOUSLY.

“Do you ever tell people no?” I ask.

“Frequently,” he says. “No to jumping a maintenance window with a body that has not slept. No to skipping rehab because the calendar is impatient. No to flying a suit that your shoulder cannot yet own. On Mars, no is a kindness. I speak it softly and with a plan for yes later.”

He laughs, the blunt Swedish laugh that ends before it begins. “A space settlement’s doctor is a polite bouncer,” he says. “I let you into your life when you are dressed for it.”

The ring brings us to the Med-Center where a small blue star above the door announces its emergency entrance without drama. He stops, not to pose, but to look at the threshold as if checking it for drift.

“Give the tour,” I say.

“Compact, deliberate,” he says. “Triage desk live twenty-four/seven. Two trauma bays that honestly we hope never earn their keep. Four ICU beds — modest, but we are brutal about escalation and evacuation windows; we do not pretend to be a tertiary center on another planet. One operating theatre, flexible — orthopedics, general, limited OB for stabilization. Imaging: ultrasound always, digital X-ray, a compact CT we treat like a family heirloom. Lab that can do the hundred things that change your mind in ten minutes and the few that change your mind in one. Pharmacy: small, disciplined, enjoys saying no to ‘just in case’ shopping lists.”

He gestures down a quieter corridor. “Mental health rooms here — sofas that are not sad, lights that taper. Group room with a window that pretends to be a window. Rehab gym: racks, flywheels, little centrifuge. Occupational med and fit-for-duty office: where I hide. Isolation suites: two negative-pressure, one positive-pressure, airlocks that my engineers admire. Telemed room for Earth consults — used sparingly, carefully, and slowly given the light minutes time-lag.”

“And the kits,” I say.

He smiles thinly. “Field kits staged by hazard: confined-space, EVA standby, hot-work. Each with its tote logic. AEDs at predictable intervals. Every crew knows where theirs lives. If they do not, I know where they live.”

We step into the foyer. A nurse glances up, sees Olof, and looks relieved for no reason beyond habit. Smilla is not on the counter. She will be asleep somewhere at perfect temperature.

“Olof,” I say, “what makes someone good here? Not the CV.”

“They enjoy Tuesols,” he says. “They narrate in short sentences and count in minutes. They believe boredom is a signal that systems are working. They touch elbows and ask about sleep. They can be kind without being pliant. They can be firm without being cruel. They respect valves. They leave good notes.”

He takes a last look back down the ring. A pair of joggers pass, then a slow-walking elder with a cane built by M&M — a perfect cane. The ring reflects them all back to themselves. Olof watches them with that small tilt of the head doctors have when they are measuring without measuring.

“Any last lines for the archive?” I ask.

He considers. “Three,” he says. “Bodies prefer load. Minds prefer company. Privacy protects courage.”

He touches the doorframe with two fingers. Monty would approve.
