"Luckily," the voice continued, "the limestone matrix does not interfere with most of our sensors here in the lab. I am going to try a low-power microwave scan first, just to see what the exterior really looks like…"
A succession of images unfolded — the cylinder's crusted surface was mapped, showing each ridge and bump and crevice in the stone — then the cylinder itself, a smooth metal tube, closed seamlessly at each end. There were no markings or signs on the outside of the metal, or at least none shown by the initial scans.
"I am initiating a low power intrusive scan, to see if the surface is permeable to x-ray."
Gretchen forced herself not to flinch as an emitter ring descended and began a pass along the length of the cylinder. At her side, she felt Maggie stiffen, and Bandao mutter: "Idiot — what if it's a booby trap, or a bomb?"
The image of the cylinder on the v-pane did not react, and a second image replaced the first. A murky picture showing the outlines of the limestone matrix, a metallic shell — very thin — and then a cavity within.
"Odd," echoed the voice from the past. "Half of the tube is solid, half empty. Wait — perhaps the solid half is only very dense…"
The image zoomed, focusing in, and zoomed again, revealing a dense, interlocking system of membranes and fluted, intertwined protrusions.
"Looks like a lung," Bandao said, staring sideways at the display.
"Some kind of structure," the voice continued, "very, very dense. The separations between the alveoli-like structures are barely measurable. Yet they exist. Hmmm…an information storage structure? Could this be a book?"
Gretchen had to suppress a start; the hard, dry voice of Green Hummingbird was whispering in her memory. A book? Or some other storage media? The man's voice started to trend upward, filling with a rush of excitement.
"It must be a book," greed dripped into his voice. "Or a visual storage mechanism. Ah, what a prize that would be! But how is it accessed?" The image shifted to focus on the empty half of the cylinder. "And what is this space for? Why use only half of the container? Hmmm…perhaps the empty half is not exactly empty?"
A glyph appeared in one corner of the recording, showing the visual feed was switching to a different sensor. Gretchen squinted at the icon, but didn't recognize the symbol. "What's that?" she asked.
"Super-shortwave sensor," Bandao answered with a slight hesitation, face tense. "It interpolates to sub-x-ray definition for medical use — but he's a fool to use a high power probe on this thing."
"…beginning scan," the recording announced. The image tightened, flashed blank, then focused again. The "empty" half of the tube was momentarily revealed as a murky soup of tiny spinning particles, then the image jerked, the tube split in half and there was a warning whoop of sound from the recording. Then everything went black and the panel beeped quietly, indicating the end of the image file.
"Well," Gretchen said after a moment. "I guess you should have been here, Mister Bandao."
The gunner shook his head, his face a tight mask. "I'm not disappointed to come late. If I had been here before, I would have put the bastard down."
With that, Bandao left, swinging angrily out of the lab and bounding off up the ring toward the main accessway. Gretchen watched him go, but said nothing, and did not call him back. Instead, she turned to Maggie and said: "Can you make this panel play back the last part frame by frame?"
The Hesht coughed in amusement, her claws dancing across the display controls.
Sighing with relief, Gretchen thumbed the release mechanisms for her helmet and heard a sharp click as they retracted. Fresh, chill air bathed her face. The ship would be cold for hours yet, until hot air streaming from the heaters permeated all compartments. Then it would be too hot until the environmentals adjusted themselves. She sat down — in something like real gravity — and tugged the helmet free from the z-suit. Parker, sitting across the table in the crew common area, slid a cup of fresh, hot coffee to her.
"There's some creamer, but no milk," he said.
"Thank you. Black is fine." The cup was very warm in her hands. Three sugar packets from a pocket of her z-suit disappeared into the oily black liquid. She took a long swallow, feeling warmth flood her chest. "Better," she said after finishing the cup. "Better. Are the Lieutenant and Flores still down in Engineering?"
Magdalena nodded, her attention focused on sucking pale red fluid and chunks of raw meat from a mealbag.
Gretchen studiously kept her eyes away from the Hesht dinner. "Mister Parker, do we have flight control and comm up?"
"Sort of," the pilot said, putting down his cup. "Attitude controls are mostly working, though there are still miles of conduit to replace for the main engines. Luckily, the fine control jets use compressed air and need only on/off signals to operate. They work fine — since they're mechanical. Navigation is up, and we have lost some planetary altitude, so when we do have engines live again I need to make an adjustment burn to put us back in the proper orbital. We have spin in this hab ring, but not the others. Main comp is up, so you have shipboard comm and info retrieval — if you can find a working display."
He turned toward Magdalena, who was squeezing the mealbag in one paw, making thick goo ooze into her open mouth. Parker jerked back toward Gretchen. "Ah…we've found the experimental transmitter, which is on its own fuel cell system, but I haven't messed with it. The cat can do that later, I guess. The main comm array is down until we rebuild power, but we're close enough to the Cornuelle that our suit radios still work."
"Unless you're in the labs," Gretchen commented, "which are shielded."
"What did you find down there?" Parker stole a glance at Bandao, who was sitting with his own cup in his hands, content to say nothing. The two Marines were equally quiet and unobtrusive, sitting back from the edge of the table. Out of his combat suit, Fitzsimmons was of medium height, very fit, with broad shoulders and curly blue-black hair. Deckard was thinner, with a lanky build and a ruddy complexion. Carlos, still looking miserable, sat beside Parker, slowly chewing on his thumb. "Did you find the…weapon?"
"Yes." Gretchen drained her cup and set it down on the spotlessly clean tabletop. "One of the scientists working on the planet — a geologist named Russovsky — found some stone cylinders in one of the canyons on the big mountain range. She brought an artifact back to base camp and showed her find to Doctor McCue, the dig supervisor. I think — not from anything said in record, but hearing between the lines — the lead archaeologist, a man named Clarkson, then took the cylinder from McCue and returned to the ship."
Gretchen looked down at the table, finding a ring of coffee-colored condensation where her warm cup had stood on the cold metal. She squeaked her finger through the liquid, drawing a line down the middle of the circle.
"Clarkson tried to see what was inside the cylinder with a high-powered sensor. Half of the tube seemed to be empty — but it wasn't, not really. Half seemed to be filled with a tightly packed membrane, like the filaments lining a human lung. The lab's isotope decay analysis estimates the cylinder is almost three million years old." A sharp, short laugh escaped her. "Clarkson was pretty sure the device wasn't working anymore, or if it was, it was a kind of book or information storage device, like a 3v pack. Well, he was right, in a way."
Her finger slashed across the circle of moisture.
"His probe injected enough energy into the empty chamber to make a sort of gas of very, very small particles expand violently. A thin wall between the two chambers broke down and the gas flooded into the membranes within a fraction of a second. They mixed, violently, and the cylinder broke open."
