Chapter Text
Curiosity's conference room's curved viewport looked out on DS9's docking ring with the station sitting close enough that the curve of the habitat ring filled a third of the window. The wall displayed schematics of a prototype tricorder rotating on the left, orbital imagery of the planet on the right, and between them a scrolling column of atmospheric and mineralogical data that kept refreshing every few seconds as the survey satellite's feed updated.
The coffee service on the side table had been picked over. Torren and Cat each had a mug. Another sat abandoned at the far end of the table near a forgotten PADD. Miles wasn't drinking anything. Admiral Tomak, a Vulcan, sat at the head of the table opposite Julian and had an untouched cup in front of him.
Julian was on his feet.
JULIAN: ...which is the first time since the Daystrom refit that anyone's had a tricorder capable of resolving through multi-band mineral interference, and the Daystrom unit is nine kilos and requires a power tether, so... not exactly field-deployable.
He gestured toward the rotating schematic without looking at it. The tricorder's internal architecture unfolded one layer at a time. First the casing, followed by the primary sensor array, and then the modified filtering stack.
JULIAN: The filtering stack is the piece we're testing. The algorithm compensates for baseline interference in real time. It builds a model of what the noise is doing, subtracts it, and shows you what's underneath. In clean environments it's redundant. You don't need it. The only way to know whether it works is to take it somewhere it has to work.
He crossed behind his chair, reached the viewport and turned.
JULIAN: Which brings us to the planet.
The orbital imagery showed a green-ansd-brown world with heavy cloud cover over the northern hemisphere and visible weather systems moving across a continental landmass. The interference overlay came up as a soft haze across the entire projection, showing variable density and shifting patterns.
JULIAN: Uncharted. Gamma Quadrant, roughly eleven light-years from the Idran terminus. A Federation probe did an orbital pass in '71, early in the exploration push. The data's been sitting in the catalog queue since. The war deprioritized a lot of routine science. Class-M, oxygen-nitrogen, temperate bands north and south of a tropical belt. Gravity point-nine-eight.
He tapped a control. The interference overlay brightened.
JULIAN: This is what makes it useful. Piezoelectric mineral deposits in the upper crust, interacting with a magnetically active atmosphere. The result is a broad-spectrum sensor haze...not dense enough to make orbit unsafe, but enough that the probe couldn't resolve anything below about forty meters of surface detail. Which means the entire orbital survey tells us there's a planet there and not much else.
TORREN: (leaning forward) Nothing at all? No structures, no...
JULIAN: No evidence of technology at the resolution we have. No radio emissions, heat signatures consistent with artificial sources, geometric patterns in the surface features, satellites, or anything indicating civilization, really. Which is not the same as saying there's nothing. It's... the instruments we have can't see anything. That's the distinction.
Tomak's hands hadn't moved.
TOMAK: Clarify that distinction, Lieutenant Commander.
Julian turned toward him, hands still moving as he spoke.
JULIAN: The probe's resolution floor is approximately forty meters. A settlement of small buildings, a spacecraft on the ground, a power signature under heavy shielding, a large structure... any of those could be present and invisible. Our working assumption is no civilization, because six years of catalogued passive data have produced no evidence of one. But the assumption is provisional.
TOMAK: And your protocol if that assumption is incorrect?
JULIAN: Standard first-contact holding pattern. The away team withdraws, the ship goes to yellow alert, we transmit a subspace notification, and we wait for Starfleet guidance. No contact without authorization.
Tomak's eyelids lowered a fraction.
TOMAK: Continue.
Julian nodded once and turned back to the displays. Miles, still not drinking anything, was silently watching the exchange with his arms crossed and his weight shifted to one side of his chair.
JULIAN: The test protocol. We put down in a temperate band in the northern continent. Coordinates selected for maximum interference density, which is also, not coincidentally, a heavily forested region with substantial mineral deposits at moderate depth. The away team deploys four prototype units. Chief O'Brien and Lieutenant Cat handle calibration; Ensign Torren and I run comparison scans against a baseline standard-issue tricorder. We map a defined area, return to the shuttle, upload to Curiosity, analyze.
Julian paused for just a moment.
JULIAN: Deployment is shuttle-based. The same interference field that makes the planet interesting makes transporter locks impossible inside the atmosphere. We've modeled it, and the signal degradation crosses threshold at approximately two kilometers above surface. So the shuttle goes down, the shuttle comes up. No beam-out option from the surface.
Miles shifted in his chair a half-inch. Nobody spoke.
JULIAN: Which means mission discipline on timing. The shuttle stays at the landing site with active engines; we're not leaving anyone without a ride. If the weather moves on us, we abort and come back when it clears. If any unit fails to check in at scheduled intervals, we collapse the perimeter and return to the shuttle. The planet is interesting. It's not so interesting that we're going to get clever about transport.
TOMAK: Environmental hazards?
JULIAN: Weather is the primary one. The planet has active convective systems. We've scheduled the deployment during a stable window, but we'll be monitoring. Secondary concerns are biological; the probe's spectroscopic data confirms an active biosphere, so we're treating it as a novel-pathogen environment. Standard decon protocol on return, full bioscan before any physical contact with surface materials.
TOMAK: And the biosphere itself? Fauna?
A half-second pause. Julian's hand came off the chair back.
JULIAN: Unknown at resolution. The probe didn't get anything useful below the size of a small building. We're packing as if we might encounter large wildlife... phasers type-two, standard issue. The away team is four officers, which is enough to maintain perimeter awareness without being a provocative presence.
TOMAK: Provocative to what?
Julian almost smiled, but resisted for the sake of professionalism.
JULIAN: Anything we can't currently see, Admiral.
Tomak considered that for a moment. He lifted his cup and set it down barely to the left of where it had been.
TOMAK: You have accounted for the parameters I would have raised. One remaining question. The prototype itself... in the event of a unit failure on the surface, is the filtering algorithm recoverable from the other three units, or does a loss of one unit compromise the test?
JULIAN: Recoverable. Each unit carries the full algorithm; they share calibration data in real-time through a local mesh, but the mesh is redundant. Losing one unit costs us cross-validation on that unit's readings. It doesn't compromise the test.
TOMAK: Then I have no further questions.
He rose. The away team rose with him. Tomak nodded to Julian and moved toward the door.
TOMAK: Good hunting, Lieutenant Commander.
The door closed behind him.
In the quiet that followed, Cat picked up her abandoned coffee cup from the far end of the table, examined it, and put it back down. Miles uncrossed his arms.
MILES: Good hunting.
He said it flat, to no one in particular. Julian turned toward him. Miles met the look.
MILES: What?
Julian looked back at the display. The planet kept rotating.
