Human presence: The Murdock Expedition of 2238 established the existence of large deep-­marine organisms known as cuttlewhales. Subsequent research at the colony designated Murdock Base demonstrated possible intelligent activity, and attempts were made to establish communications in 2244. Contact with the colony abruptly ended in early 2247, and there has been no futher contact since… .

The Commonwealth government had decided that word from the research colony on the ice out there on Abyssworld was too long overdue, and they were dispatching a small Navy task force and some Marines to find out what had happened. The Marines were volunteers drawn from First, Second, and Third Platoons, plus the headquarters platoon of Bravo Company, forty-­two men and women in all, and all of them blooded both by combat and by experience on extrasolar worlds. Lieutenant Lyssa Kemmerer, Captain Reichert’s exec, would be leading us.

The five Navy Corpsmen, however, were not volunteers. Where the Marines went, we would go as well.

The company’s senior Corpsman was Chief Richard R. Garner, an old hand with gold hash marks running halfway up his dress uniform sleeve, each stripe showing four years of good-­conduct duty. He was a bluff, craggy, no-­nonsense sort, and when he barked at you he meant business.

Garner called us to a briefing the next morning. There were four of us sitting in the lounge in front of Garner—­me and Dubois, plus HM1 Charlie “Machine” McKean and HM2 Kari Harris.

There was another man present as well, a Navy lieutenant commander with the gold caduceus at his throat indicating he was Medical Corps.

“Good morning, ­people,” Garner began. “We’ve been tapped as tech support for an important mission, and it’s important to get this off on the right foot. We’ll be transferring to the USRS Haldane tomorrow. There’s a download waiting for each of you giving billeting information and duty schedules.”

DuBoise and McKean both groaned. Harris remained impassive.

“Knock it off,” Garner said. “First off, it is my pleasure to introduce Dr. Lyman Kirchner, fresh up-­El from Sam-­Sea. He will be our department head on this expedition.”

I looked at Kirchner with curiosity. He was a small older man with an intense gaze that made me uncomfortable. If he was from SAMMC, though, he would be good. I wondered about his age, though. His white hair was thickly interspersed with black, and his face, with deep-­set wrinkles, was an odd mixture of weathered skin and baby-­pink new.

Anagathic treatments. He was under treatment for that most deadly of the diseases to afflict Humankind—­old age.

“Dr. Kirchner,” Garner continued, “was chief of the xenopathology department at Sam-­Sea, so he will be our expedition xenologist as well as ship’s doctor. We’re very lucky to have him on board.”

And that was a relief. I’d been wondering since Singer had told me I was being assigned to this mission whether we’d have a medical officer on board. I knew that Garner was IDC, but none of the rest of us were.

Independent-­duty Corpsmen were the medical department on ships or bases too small to have a ship’s doctor, and that was a hellacious responsibility. Oh, we operated independently in the field as often as not … but it was always good to have a real doctor backing you up.

You know, even today, we still hear the story of an independent-­duty Corpsman during the Second World War—­we were called Pharmacy Mates in those days—­who successfully performed an appendectomy while on board a submarine, the USS Seadragon, while she was on her fourth war patrol, in 1942. He was twenty-­three-­year-­old PhM1/c Wheeler B. Lipes—­a first class, like McKean.

In fact, though it’s not well known, there were three emergency appendectomies carried out by Pharmacy Mates on board Navy submarines during that war, this when the only commonly available antibiotics were powdered sulfanilamide and phenol, and the only anesthetic was ether. My God! The responsibility those guys faced was staggering! But, damn it, when there were no qualified surgeons within a thousand miles, you did what you had to do… .

Kirchner stood and acknowledged Garner’s introduction. “Thank you, Chief.” He glared at us. “No speeches, ­people. I know you’re well trained, I know you’re experienced, and I know you’re going to do your jobs competently and well. With pre-­screening of the ship’s complement, we shouldn’t have any major health issues, and Haldane’s medical department will be able to focus on the tech support at GJ 1214. So do your jobs, do what you’re told, and we’ll all get along just fine. Chief Garner?”

“Thank you, sir.” Garner turned to face us again. “Okay, I want all of you to pull down the Abyss Deep docuinteractive from the Clymer’s library. On your own time.”

“Aw, Chief,” Dubois said. “What for? The place is nothing but a freaking ice ball.” He’d been angry ever since his orders had come down telling him he was deploying to Abyss Deep, and he didn’t mind letting everyone else within range know it.

“Can the gripeload, Doobie. That goddamn bleak ball of ice can kill you faster and in more ways than a Qesh Daitya platform.”

McKean and Harris both grumbled a bit, too, and, I have to admit, I did as well. Sailors hate having official shit intrude on their precious downtime, and I already had the extra duty tagged onto my daily schedule by my NJP. But as the ancient adage has it, a griping sailor is a happy sailor. Garner had scored a point by bringing up the Dait­yas, heavy-­weapons platforms named for a class of giant or demon in Hindu mythology. We’d faced Qesh Daityas out on Bloodworld, and had a healthy respect for the things.

“Okay,” Garner went on, “we’re slated to board the Haldane tomorrow evening. Our civilian … guests will be joining us on board. They are Dr. Carla Montgomery and Dr. Raúl Ortega. Montgomery is an expert on exobiology. Ortega is an expert on planets and environments with extreme temperatures or other exotic conditions.

“We have absolutely no idea what happened to Murdock Base. None. The last report from there, via robot courier, mentioned sightings of the autochthones, the native life, but no contact … and no danger. The next courier was due from them four days later. It’s been three weeks, now, with no word from them whatsoever. We must assume that the base has suffered some significant problem. It may be as minor as a failure in the AIs they use to launch and transmit to the couriers. Or it may be more serious. A lot more serious.

“So they’re sending in the Marines. And us.”

More download information flooded through our in-­heads, a schematic view of a multilevel dome equipped with living quarters, common areas, airlocks, and a large central laboratory space.

“The base,” Garner went on, “is a standard nano-­grown all-­climate dome, with several outlying structures … but only the main dome is pressurized. The colony consists of eighty-­five men and women—­mostly science staff, but including admin and support—­plus twelve M’nangat in four family triads. The M’nangat are there to liaise with the EG, if need be, in order to conduct deep research on any locals that they might manage to contact.”

The Brocs had become more and more important as we researched the labyrinth of data that was the Encyclopedia Galactica. Our best guess right now is that we have been able to access something less than one hundredth of 1 percent of the EG data that’s out there, and we wouldn’t have been able to tap that much if not for M’nangat help. If the organisms discovered on GJ 1214 I were intelligent—­and that was by no means certain yet—­there ought to be a listing and a lot more data available on the local EG nodes.

As yet we could find nothing, but that didn’t mean it wasn’t there. There are an estimated 50 to 100 million intelligent species scattered through our Galaxy, and perhaps a thousand times that number that have existed during the past billion years, but which now are extinct. Many, though by no means all, of these have entries in the EG. Technic species that discover the EG and learn how to tap in, sometimes, though not always, list themselves. Atechnic species—­marine organisms that have never discovered fire and metal smelting, for instance—­or the more inwardly focused species who have turned their backs on space travel are often described by others who encounter them.

For a billion years—­as long as multicellular life has existed on Earth—­the Encyclopedia Galactica has grown in both size and complexity, with millions of separate channels, nested frequencies, and deep-­heterodyned polylogues. Lots of channels we can’t even access yet; we’re certain there are neutrino channels, for instance, but we don’t know how to read them. When we discovered the local node at Sirius, just 8.6 light years from Earth, we swiftly decided that we needed friendly native guides to lead us through the data jungles.

We would have copies of small parts of the EG with us at GJ 1214, as much as could be accommodated by the Haldane’s sizeable quantum computer storage. We’re still working out how the EG is organized, but we think it includes data on all nearby stars in the direction of the constellation Ophiuchus, which is where GJ 1214 is located in the night sky. With luck, we’d scooped up the still-­hidden entry on Abyssworld along with known nearby stars in that region—­70 and 36 Ophiuchi, Sabik, Raselhague, and others—­and our AIs could be hacking through the jungle while we worked.

Eventually the briefing ended—­a lot of talk with no surprises—­and I went back to work. I was working in the Clymer’s main sick bay that week, which meant the usual shipboard morning routine of sick call, screening Marines and naval personnel who were showing up with problems ranging from colds to an eye infection to a full-­blown case of pneumonia. The pneumonia actually was easier to treat than the colds. Despite our much-­vaunted advances in medical technology over the past ­couple of centuries, the collection of minor infections and immune-­system failures known as “the common cold” is still tough to treat other than purely symptomatically. Rather than being a single malady, the complaint we call a cold can be caused by any of some two hundred different viruses. The rhinovirus associated with the majority of colds alone has ninety-­nine serotypes. That makes it tough to program an injection of nanobots to go in and kill the viruses, and the preferred treatment remains taking care of the symptoms rather than the cause.

There were an unusual number of colds this morning, though, so I pulled some nasopharyngeal samples and sent them up to the lab for a full serotypal workup. We often had these little micro epidemics running their course of the ship when we were in port. Sailors and Marines went ashore on liberty, of course—­even taking the elevator down-­El to Earth—­and they were exposed to bugs they wouldn’t have otherwise encountered if they’d stayed on board. If we could identify a specific strain of virus, we could whip up a nanobot to attack it. In the meantime, though, I’d stick with the old-­fashioned treatment—­acetaminophen, chlorpheniramine maleate, phenylephrine hydrochloride, and dextromethorphan, plus lots of water. The pain reliever, the antihistamine, the decongestant, and the cough suppressant would do everything a round of nanobots would, and—­heresy!—­might even do it better.

At a few past 1700 hours I checked out of sick bay and reported to Chief Garner, who was in charge of handing out my extra-­duty hours each evening. He just grinned at me and said, “You have your duty assignment, Carlyle. Go bone up on Abyss Deep.”

So after a quick sonoshower back in my quarters, I prepared to climb into my rack-­tube to take the sim. Just as I slipped inside, though, a call came through from Doob, suggesting that we rack out together in the ship’s lounge. I told him I’d meet him there.

“E-­Car!” he called as I entered the lounge. “Let’s get this fucking sim out of the way, okay? I have a hot date tonight and I’m damned if I’m going to miss it.”

“Who is it, Doob? Carla again?” HM3 Carla Harper was a lab assistant whom Dubois had bedded … a lot. There was a pool running among some of the platoon Corpsmen as to whether or not he would pop the question, and when.

“Nah. Someone new.”

“Someone new? My God, it’s the end of life as we know it!”

“Knock it off.”

“Who is it?”

“None of your damned business!” He scowled at me. “What I wanna know is how come you get in trouble, but I get to share in the punishment!”

“Welcome to the Navy,” I told him. “At least you didn’t get two weeks’ restriction.”

“What restriction? We boost for Abyssworld day after tomorrow, we’ll be gone a ­couple of months at least, and all you miss is a ­couple of liberties!”

That stopped me. I hadn’t thought about that. Restriction means you stay in your quarters except when you’re going about your normal day-­to-­day duties, or eating in the mess hall, or doing whatever your CO tells you to do … so Doob was right. Maybe I had gotten off light.

“Okay, Doobie,” I told him. “You wanna tag the ’interactive together? It’ll go faster that way, and you can be off to your mystery date.”

“My thought exactly, E-­Car.”

I thoughtclicked an internal control. “Compartment, two chairs, downloungers with full link capability. Here and here.”

The active nanomatrix in the deck obediently shaped two areas into egg-­shaped chairs, both almost completely enclosed except for the oval front openings, and with deeply padded interiors that let you stretch out and back in fair comfort. I backed into one, brought my palm contacts down on the link board, and ordered a library download of the required docuinteractive.

Dubois dropped into the second seat. “I hate these things.”

“I kind of like ’em,” I replied. “Just like being there, but you don’t get eaten by the bug-­eyed monster.”

“That’s the problem. You get used to ignoring dangers in a sim, they could bite you for real when you’re actually there.”

“So? Don’t be complacent. The idea is that we can step into another world and learn about it experientially. No surprises when you step into the world for real.”

“So, what did the chief call it? ‘That goddamn bleak ball of ice?’ No fun at all, man!”

“I didn’t realize we were going out there to have fun!” I nestled back into the yielding foam of the seat and put my palm on the contact pad.

There was a burst of in-­head static, and then I was standing on the surface of Abyssworld.

My God, I thought. “Goddamn bleak” doesn’t even begin to cover it… .

Chapter Six

A bit of background came down the link first.

The formal name of the place is GJ 1214 I, but most ­people call it either Abyssworld or Abyss Deep. The data we were simming had been sent back to Earth just five years ago, but in fact the world has been known since the early twenty-­first century. It was discovered by the MEarth Project, which was searching for extrasolar planets by watching for minute dips in the brightness of some thousands of red dwarfs, an indicator of a planet transiting the star’s face. They used red dwarfs because it was easier to record light fluctuations against a dimmer light source, and because planets circling red dwarfs tended to be tucked in a lot closer to their parent suns, and therefore had orbital periods measured in days as opposed to months or years. In 2009, the planet named—­by the astronomical convention of the day—­GJ 1214b was first detected, and subsequent observations showed that it was a so-­called super-­Earth, with more than six and a half times Earth’s mass and over two and a half times Earth’s diameter.

The real surprise came when they did the math and determined that the new planet had a density of just one-­third of Earth’s, which meant that the huge world had a quite small rocky core covered by either ice or liquid water.

It was, in fact, the first true ocean exoplanet discovered; the side of the world eternally locked beneath a small sun just 2 million and some kilometers away was hot, well above the boiling point of water. At first it was assumed that the surface of any world so close to its parent would have to be well above habitable temperatures. The measured equilibrium temperatures, however, turned out to be from dayside cloud decks; the nightside was cold enough that the global ocean was half covered by a permanent ice cap, with the entire night hemisphere locked in ice.

The extreme differences in temperature between the day and night hemispheres, though, resulted in some absolutely incredible storms.

If Dubois and I had really been standing on the edge of the Abyss Deep icepack in nothing but our shipboard utilities, we would have been dead in moments. The environment was nothing short of hellish, balanced precariously between frigid ice and scalding steam, with a poisonous pea-­soup-­fog atmosphere and a wind thundering in from the day with tornadic force. The docuinteracive wasn’t recreating all of the possible physical sensations, though. I could see water spray and surface clouds whipping past me, hear the deafening roar of moving air, but the wind didn’t sweep me off my feet. The two of us could stand there, at the very edge of the ice, and take in the view.

And the view was … spectacular.

Despite both high-­altitude cloud decks and the scud whipping across the surface of water and ice, I could see the star on the knife-­edge horizon across the purple-­red ocean, a swollen, deep ruby dome mottled by vast, ragged sunspots. Clouds—­black, green, and purple—­banked hugely to either side in an emerald sky; lightning played along the horizon. As I watched, fast-­moving clouds filled the momentary crack in the sky that had revealed the star, blotting it out.

In the opposite direction, the sky grew darker still and heavy with snow. Ice, undulating and raw, ran off into the distance in a barren white desert, punctuated here and there by upthrusts—­slabs, pillars, daggers, and tumbled blocks of ice, some of them hundreds of meters across. A hundred meters away, a low, bright orange dome added a spot of color to the endless white—­the colony’s main dome. Smaller domes and Quonset-­style huts were scattered about nearby, and I could see a large, bright yellow quantum spin-­floater grounded outside the main entrance to the base.

The colony was obscured by a sudden gust of spray and windblown snow. It made me shiver just looking at it, though I couldn’t feel the actual cold.

“The place is a lot like Bloodworld,” Dubois said, turning to look back out to sea. We were standing at the edge of the icepack, though waves and spray made it a little difficult to tell exactly where the sea ended, and the ice began. “Hurricanes, high winds, hellacious storms …”

“It’s worse,” a voice told us. We turned and faced the program’s interactive agent, an older man with the look of a college professor. “I’m Dr. Murdock. I’ll be your guide to Abyss Deep this evening.”

Well, it wasn’t the real Dr. Murdock, of course, since the Abyssworld Expedition’s science team leader was currently on the planet some forty-­two light years away … assuming he was even alive now. Based on the real James Eric Murdock, the man in a civilian tunic and dark slacks was a computer-­generated image, data seamlessly woven together inside our heads by Clymer’s library AI. This simulation component was the whole point of a docuinteractive; we could ask the program questions, and it could take us through the landscape as if we were really there. The AI running the show was programmed to incorporate the voice, mannerisms, and recorded thoughts of the real Murdock, and present them as though we were actually there.

The simulated Murdock held out his hand, palm up, and a small globe representing the planet came up between us. He rotated it in front of us.

“We call the main atmospheric disturbance Abysstorm,” he said. “It’s generated by the heat of the star, and serves to transfer that heat across the planet.”

On the globe, Abyss Deep’s dayside was blanketed by a perpetual hurricane many thousands of kilometers across, pinned in place by the glare of the star directly over its eye. It showed vast, far-­reaching spirals of cloud that reached across half the planet. The nightside was completely covered by ice.

“Hang on a sec,” Dubois said, pointing. “Something’s wrong. Hurricanes are caused by the spin of the planet. Coriolis effect, right? Abyss Deep doesn’t rotate, so the winds ought to blow straight back from dayside to night.”

The simulated Dr. Murdock gave him a sharp look. “Idiot. Why do you say the planet doesn’t rotate? Of course it does.”

“Hey!” Doob said. Evidently he wasn’t used to personality coming through in a sim along with basic information. Murdock reminded me of an acid, acerbic professor of A and P—­anatomy and physiology—­I remembered from my training in San Antonio. He’d called students “idiot,” and worse, as well.

“ ‘Tidally locked means the planet rotates once in its year,” I put in.

“Precisely,” Murdock said. “GJ 1214 I does spin, and does so fairly quickly, quickly enough that it generates its own magnetic field, which is a damned good thing considering the background radiation flux from the star. It makes one rotation in just over a day and a half as it moves around its star, its day perfectly matching its year.

“The storm dynamics are quite complex, with smaller storms constantly spinning off of the one big one and following gently curved tracks around the planet and into the night. The atmosphere is fairly thin, about half of Earth’s atmospheric pressure at the surface, so a lot of the heat dissipates before it reaches the nightside. The world-­ocean traps a lot of it. Most of the dissipation, however, appears to be through molecular escape. The star turns water into steam, which rises high in the atmosphere above the Abysstorm. Solar radiation then blasts a lot of that water completely away from the planet. See?”

The model of Abyss Deep floating above Murdock’s hand developed a faint, ghostly tail streaming away from the daylight side. “In many ways,” he continued, “Abyssworld is similar to a comet … a very large comet with a tail of hot gasses blowing away from the local star.”

“That can’t be a stable configuration,” I said. “It’s losing so much mass that the whole planet is going to boil away.”

“Correct. We believe Abyssworld formed much farther out in the planetary system, then migrated inward as a result of gravitational interactions with the two outer gas giants. We don’t have a solid dating system with which to work, but it’s possible that the planet began losing significant mass as much as five billion years ago, when it would have been perhaps six times the diameter it is now.

“Abyssworld is now losing mass, which has the advantage of bleeding away excess heat. Within another billion years, though, this ongoing loss of mass will significantly reduce the planet’s size, until the entire world ocean has boiled away. At that point, Abyssworld will be dead.”
