“Uh, hi, this is BladeNinja43. I was wondering just what it is that you guys are hoping to discover out there.”
“That’s an extremely good question,” Alan lied. “And the answer is: We don’t know! This is a voyage of discovery, and we’re engaged in what’s called ‘pure science.’ Now, time and time again, the purest research has turned out to be extremely profitable. But we’re not looking that far ahead. We’re just hoping to find something absolutely unexpected.”
“My God, you’re slick,” Lizzie marveled.
“I’m going to edit that from the tape,” Alan said cheerily. “Next up.”
“This is Mary Schroeder, from the United States. I teach high school English, and I wanted to know for my students, what kind of grades the three of you had when you were their age.”
Alan began. “I was an overachiever, I’m afraid. In my sophomore year, first semester, I got a B in Chemistry and panicked. I thought it was the end of the world. But then I dropped a couple of extracurriculars, knuckled down, and brought that grade right up.”
“I was good in everything but French Lit,” Consuelo said.
“I nearly flunked out!” Lizzie said. “Everything was difficult for me. But then I decided I wanted to be an astronaut, and it all clicked into place. I realized that, hey, it’s just hard work. And now, well, here I am.”
“That’s good. Thanks, guys. Here’s the third, from Maria Vasquez.”
“Is there life on Titan?”
“Probably not. It’s cold down there! 94° Kelvin is the same as -179° Celsius, or -290° Fahrenheit. And yet… life is persistent. It’s been found in Antarctic ice and in boiling water in submarine volcanic vents. Which is why we’ll be paying particular attention to exploring the depths of the ethane-methane sea. If life is anywhere to be found, that’s where we’ll find it.”
“Chemically, the conditions here resemble the anoxic atmosphere on Earth in which life first arose,” Consuelo said. “Further, we believe that such pre-biotic chemistry has been going on here for four and a half billion years. For an organic chemist like me, it’s the best toy box in the universe. But that lack of heat is a problem. Chemical reactions that occur quickly back home would take thousands of years here. It’s hard to see how life could arise under such a handicap.”
“It would have to be slow life,” Lizzie said thoughtfully. “Something vegetative. ‘Vaster than empires and more slow.’ It would take millions of years to reach maturity. A single thought might require centuries… .”
“Thank you for that, uh, wild scenario!” Alan said quickly. Their NAFTASA masters frowned on speculation. It was, in their estimation, almost as unprofessional as heroism. “This next question comes from Danny in Toronto.”
“Hey, man, I gotta say I really envy you being in that tiny little ship with those two hot babes.”
Alan laughed lightly. “Yes, Ms. Hong and Ms. O’Brien are certainly attractive women. But we’re kept so busy that, believe it or not, the thought of sex never comes up. And currently, while I tend to the Clement , they’re both on the surface of Titan at the bottom of an atmosphere sixty percent more dense than Earth’s, and encased in armored exploration suits. So even if I did have inappropriate thoughts, there’s no way we could…”
“Hey, Alan,” Lizzie said. “Tell me something.”
“Yes?”
“What are you wearing?”
“Uh… Switching over to private channel.”
“Make that a three-way,” Consuelo said.
Ballooning, Lizzie decided, was the best way there was of getting around. Moving with the gentle winds, there was no sound at all. And the view was great!
People talked a lot about the “murky orange atmosphere” of Titan, but your eyes adjusted. Turn up the gain on your helmet, and the white mountains of ice were dazzling! The methane streams carved cryptic runes into the heights. Then, at the tholin-line, white turned to a rich palette of oranges, reds, and yellows. There was a lot going on down there—more than she’d be able to learn in a hundred visits.
The plains were superficially duller, but they had their charms as well. Sure, the atmosphere was so dense that refracted light made the horizon curve upward to either side. But you got used to it. The black swirls and cryptic red tracery of unknown processes on the land below never grew tiring.
On the horizon, she saw the dark arm of Titan’s narrow sea. If that was what it was. Lake Erie was larger, but the spin doctors back home had argued that since Titan was so much smaller than earth, relatively it qualified as a sea. Lizzie had her own opinion, but she knew when to keep her mouth shut.
Consuelo was there now. Lizzie switched her visor over to the live feed. Time to catch the show.
“I can’t believe I’m finally here,” Consuelo said. She let the shrink-wrapped fish slide from her shoulder down to the ground. “Five kilometers doesn’t seem like very far when you’re coming down from orbit—just enough to leave a margin for error so the lander doesn’t come down in the sea. But when you have to walk that distance, through tarry, sticky tholin… well, it’s one heck of a slog.”
“Consuelo, can you tell us what it’s like there?” Alan asked.
“I’m crossing the beach. Now I’m at the edge of the sea.” She knelt, dipped a hand into it. “It’s got the consistency of a Slushy. Are you familiar with that drink? Lots of shaved ice sort of half-melted in a cup with flavored syrup. What we’ve got here is almost certainly a methane-ammonia mix; we’ll know for sure after we get a sample to a laboratory. Here’s an early indicator, though. It’s dissolving the tholin off my glove.” She stood.
“Can you describe the beach?”
“Yeah. It’s white. Granular. I can kick it with my boot. Ice sand for sure. Do you want me to collect samples first or release the fish?”
“Release the fish,” Lizzie said, almost simultaneously with Alan’s “Your call.”
“Okay, then.” Consuelo carefully cleaned both of her suit’s gloves in the sea, then seized the shrink-wrap’s zip tab and yanked. The plastic parted. Awkwardly, she straddled the fish, lifted it by the two side-handles, and walked it into the dark slush.
“Okay, I’m standing in the sea now. It’s up to my ankles. Now it’s at my knees. I think it’s deep enough here.”
She set the fish down. “Now I’m turning it on.”
The Mitsubishi turbot wriggled, as if alive. With one fluid motion, it surged forward, plunged, and was gone.
Lizzie switched over to the fishcam.
Black liquid flashed past the turbot’s infrared eyes. Straight away from the shore it swam, seeing nothing but flecks of paraffin, ice, and other suspended particulates as they loomed up before it and were swept away in the violence of its wake. A hundred meters out, it bounced a pulse of radar off the sea floor, then dove, seeking the depths.
Rocking gently in her balloon harness, Lizzie yawned.
Snazzy Japanese cybernetics took in a minute sample of the ammonia-water, fed it through a deftly constructed internal laboratory, and excreted the waste products behind it. “We’re at twenty meters now,” Consuelo said. “Time to collect a second sample.”
The turbot was equipped to run hundreds of on-the-spot analyses. But it had only enough space for twenty permanent samples to be carried back home. The first sample had been nibbled from the surface slush. Now it twisted, and gulped down five drams of sea fluid in all its glorious impurity. To Lizzie, this was science on the hoof. Not very dramatic, admittedly, but intensely exciting.
