The radio came on.
"Hell."
Martha kept her eyes forward, concentrated on walking. Jupiter to one shoulder, Daedalus's plume to the other. Nothing to it. Just trudge, drag, trudge, drag. Piece of cake.
"Oh."
She chinned the radio off.
Click.
"Hell. Oh. Kiv. El. Sen."
"Shut up, shut up, shut up!" Martha gave the rope an angry jerk, making the sledge carrying Burton's body jump and bounce on the sulfur hardpan. "You're dead, Burton, I've checked, there's a hole in your faceplate big enough to stick a fist through, and I really don't want to crack up. I'm in kind of a tight spot here and I can't afford it, okay? So be nice and just shut the fuck up."
"Not. Bur. Ton."
"Do it anyway."
She chinned the radio off again.
Jupiter loomed low on the western horizon, big and bright and beautiful and, after two weeks on Io, easy to ignore. To her left, Daedalus was spewing sulfur and sulfur dioxide in a fan two hundred kilometers high. The plume caught the chill light from an unseen sun and her visor rendered it a pale and lovely blue. Most spectacular view in the universe, and she was in no mood to enjoy it.

Before the voice could speak again, Martha said, "I am not going crazy, you're just the voice of my subconscious, I don't have the time to waste trying to figure out what unresolved psychological conflicts gave rise to all this, and I am not going to listen to anything you have to say."
Silence.
The moonrover had flipped over at least five times before crashing sideways against a boulder the size of the Sydney Opera House. Martha Kivelsen, timid groundling that she was, was strapped into her seat so tightly that when the universe stopped tumbling, she'd had a hard time unlatching the restraints. Juliet Burton, tall and athletic, so sure of her own luck and agility that she hadn't bothered, had been thrown into a strut.
The vent-blizzard of sulfur dioxide snow was blinding, though. It was only when Martha had finally crawled out from under its raging whiteness that she was able to look at the suited body she'd dragged free of the wreckage.
She immediately turned away.
Whatever knob or flange had punched the hole in Burton's helmet had been equally ruthless with her head.
Where a fraction of the vent-blizzard–"lateral plumes" the planetary geologists called them–had been deflected by the boulder, a bank of sulfur dioxide snow had built up. Automatically, without thinking, Martha scooped up double-handfuls and packed them into the helmet. Really, it was a nonsensical thing to do; in a vacuum, the body wasn't about to rot. On the other hand, it hid that face.
Then Martha did some serious thinking.
For all the fury of the blizzard, there was no turbulence. Because there was no atmosphere to have turbulence in. The sulfur dioxide gushed out straight from the sudden crack that had opened in the rock, falling to the surface miles away in strict obedience to the laws of ballistics. Most of what struck the boulder they'd crashed against would simply stick to it, and the rest would be bounced down to the ground at its feet. So that–this was how she'd gotten out in the first place–it was possible to crawl under the near-horizontal spray and back to the ruins of the moonrover. If she went slowly, the helmet light and her sense of feel ought to be sufficient for a little judicious salvage.
Martha got down on her hands and knees. And as she did, just as quickly as the blizzard had begun–it stopped.
She stood, feeling strangely foolish.
Still, she couldn't rely on the blizzard staying quiescent. Better hurry, she admonished herself. It might be an intermittent.
Quickly, almost fearfully, picking through the rich litter of wreckage, Martha discovered that the mother tank they used to replenish their airpacks had ruptured.
Terrific. That left her own pack, which was one-third empty, two fully charged backup packs, and Burton's, also one-third empty. It was a ghoulish thing to strip Burton's suit of her airpack, but it had to be done. Sorry, Julie. That gave her enough oxygen to last, let's see, almost forty hours.
Then she took a curved section of what had been the moonrover's hull and a coil of nylon rope, and with two pieces of scrap for makeshift hammer and punch, fashioned a sledge for Burton's body.
She'd be damned if she was going to leave it behind.

"This is. Better."
"Says you."
Ahead of her stretched the hard, cold sulfur plain. Smooth as glass. Brittle as frozen toffee. Cold as hell. She called up a visor-map and checked her progress.
Only forty-five miles of mixed terrain to cross and she'd reach the lander. Then she'd be home free. No sweat, she thought. Io was in tidal lock with Jupiter. So the Father of Planets would stay glued to one fixed spot in the sky. That was as good as a navigation beacon. Just keep Jupiter to your right shoulder, and Daedalus to your left. You'll come out fine.
"Sulfur is. Triboelectric."
"Don't hold it in. What are you really trying to say?"
"And now I see. With eye serene. The very. Pulse. Of the machine." A pause.
"Wordsworth."
Which, except for the halting delivery, was so much like Burton, with her classical education and love of classical poets like Spenser and Ginsberg and Plath, that for a second Martha was taken aback. Burton was a terrible poetry bore, but her enthusiasm had been genuine, and now Martha was sorry for every time she'd met those quotations with rolled eyes or a flip remark. But there'd be time enough for grieving later. Right now she had to concentrate on the task at hand.
The colors of the plain were dim and brownish. With a few quick chin-taps, she cranked up their intensity. Her vision filled with yellows, oranges, reds–intense wax crayon colors. Martha decided she liked them best that way.
For all its Crayola vividness, this was the most desolate landscape in the universe.
She was on her own here, small and weak in a harsh and unforgiving world.
Burton was dead. There was nobody else on all of Io. Nobody to rely on but herself. Nobody to blame if she fucked up. Out of nowhere, she was filled with an elation as cold and bleak as the distant mountains. It was shameful how happy she felt.
After a minute, she said, "Know any songs?"
Oh the bear went over the mountain. The bear went over the mountain. The bear went over the mountain. To see what he could see.
"Wake. Up. Wake. Up."
To see what he could–
"Wake. Up. Wake. Up. Wake."
"Hah? What?"
"Crystal sulfur is orthorhombic."
She was in a field of sulfur flowers. They stretched as far as the eye could see, crystalline formations the size of her hand. Like the poppies of Flanders field. Or the ones in The Wizard of Oz. Behind her was a trail of broken flowers, some crushed by her feet or under the weight of the sledge, others simply exploded by exposure to her suit's waste heat. It was far from being a straight path. She had been walking on autopilot, and stumbled and turned and wandered upon striking the crystals.
Martha remembered how excited she and Burton had been when they first saw the fields of crystals. They had piled out of the moonrover with laughter and bounding leaps, and Burton had seized her by the waist and waltzed her around in a dance of jubilation. This was the big one, they'd thought, their chance at the history books. And even when they'd radioed Hols back in the orbiter and were somewhat condescendingly informed that there was no chance of this being a new life-form, but only sulfide formations such as could be found in any mineralogy text ... even that had not killed their joy. It was still their first big discovery.
