Sax switched off his screen after one such depressing hour, and joined Michel for supper out in his rover.
Theres no such thing as a fresh start, he said as he put water on to boil.
The Big Bang? Michel suggested.
As I understand it, there are theories suggesting that the the dumpiness of the early universe was caused by the earlier-dumpiness of the previous universe, collapsing down into its Big Crunch.
I would have thought that would crush all irregularities.
Singularities are strange outside their event horizons, quantum effects allow some particles to appear. Then the cosmic inflation blasting those particles out apparently caused small clumps to start and become big ones. Sax frowned; he was sounding like the Da Vinci theory group. But I was referring to the flood on Earth. Which is not as complete an alteration of conditions as a singularity, by any means. In fact there must be people down there who dont think of it as a break at all.
True. For some reason Michel was laughing. We should go down there and see, eh?
As they finished eating their spaghetti Sax said, I want to get out in the field. I want to see if there are any visible effects of the mirrors going away.
You already saw one. That dimming of the light, when we were out on the rim Michel shuddered.
Yes, but that only makes me more curious.
Well well hold down the fort for you.
As if one had physically to occupy any given space in order to be there. The cerebellum never gives up, Sax said.
Michel grinned. Which is why you want to go out and see it in person.
Sax frowned.
Before he left, he called Ann.
Would you like to, to accompany me, on a trip to South Tharsis, to, to, to examine the upper boundary of the areobio-sphere, together?
She was startled. Her head was shaking back and forth as she thought it over the cerebellums answer, some six or seven seconds ahead of her conscious verbal response: No. And then she cut the connection, looking somewhat frightened.
Sax shrugged. He felt bad. He saw that one of his reasons for going into the field had to do with getting Ann out there, showing her the fellfields himself. Showing her how beautiful they were. Talking to her. Something like that. His mental image of what he would say to her if he actually got her out there was fuzzy at best. Just show her. Make her see it.
Well, one couldnt make people see things.
He went to say goodbye to Michel. Michels entire job was to make people see things. This was no doubt the cause of the frustration in him when he talked about Ann. She had been one of his patients for over a century now and still she hadnt changed, or even told him very much about herself. It made Sax smile a little to think of it. Though clearly it was vexing for Michel, who obviously loved Ann. As he did all his old friends and patients, including Sax. It was in the nature of a professional responsibility, as Michel saw it to fall in love with all the objects of his scientific study. Every astronomer loves the stars. Well, who knew. Sax reached out and clasped Michels upper arm, who smiled happily at this unSaxlike behaviour, this change in thinking. Love, yes; and how much more so when the object of study consisted of women known for years and years, studied with the intensity of pure science yes, that would be a feeling. A great intimacy, whether they co-operated in the study or not. In fact they might even be more beguiling if they didnt co-operate, if they refused to answer any questions at all. After all if Michel wanted questions answered, answered at great length even when they werent asked, he always had Maya, Maya the all-too-human, who led Michel on a hard steeplechase across the limbic array, including throwing things at him, if Spencer was to be believed. After that kind of symbolism, the silence of Ann might prove to be very endearing. Be careful, Michel said: the happy scientist, with one of his areas of study standing before him, loved like a brother.
Sax took a solo rover and drove it down the steep, bare southern slope of Pavonis Mons, then across the saddle between Pavonis and Arsia Mons. He contoured around the great cone of Arsia Mons on its dry eastern side. After that he drove down the southern flank of Arsia, and of the Tharsis bulge itself, until he was on the broken highlands of Daedalia Planitia. This plain was the remnant of a giant ancient impact basin, now almost entirely erased by the uptilt of Tharsis, by lava from Arsia Mons, and by the ceaseless winds, until nothing was left of the impact basin except for a collection of areologists observations and deductions, faint radial arrays of ejecta scrapes and the like, visible on maps but not in the landscape.
To the eye as one travelled over it, it looked like much of the rest of the southern highlands: rugged, bumpy, pitted, cracked land. A wild rockscape. The old lava flows were visible as smooth lobate curves of dark rock, like tidal swells fanning out and down. Wind streaks both light and dark marked the land, indicating dust of different weights and consistencies: there were light, long triangles on the southeast sides of craters and boulders, dark chevrons to the northwest of them, and dark splotches inside the many rimless craters. The next big dust storm would redesign all these patterns.
Sax drove over the low stone waves with great pleasure, down down up, down down up, reading the sand paintings of the dust streaks like a wind chart. He was travelling not in a boulder car, with its low, dark room and its cockroach scurry from one hiding place to the next, but rather in a big, boxy areologists camper, with windows on all four sides of the third-storey drivers compartment. It was a very great pleasure indeed to roll along up there in the thin, bright daylight, down and up, down and up, down and up over the sand-streaked plain, the horizons very distant for Mars. There was no one to hide from; no one hunting for him. He was a free man on a free planet, and if he wanted to he could drive this car right around the world. Or anywhere he pleased.
The full impact of this feeling took him about two days drive to realize. Even then he was not sure that he comprehended it. It was a sensation of lightness, a strange lightness that caused little smiles to stretch his mouth repeatedly for no obvious reason. He had not been consciously aware, before, of any sense of oppression or fear but it seemed it had been there since 2061, perhaps, or the years right before it. Sixty-six years of fear, ignored and forgotten but always there a kind of tension in the musculature, a small hidden dread at the core of things. Sixty-six bottles of fear on the wall, sixty-six bottles of fear! Take one down, pass it around, sixty-five bottles of fear on the wall!
Now gone. He was free, his world was free. He was driving down the wind-etched tilted plain, and earlier that day snow had begun to appear in the cracks, gleaming aquatically in a way dust never did; and then lichen; he was driving down into the atmosphere. And no reason, now, why his life ought not to continue this way, puttering about freely every day in his own world lab, and everybody else just as free as that!
It was quite a feeling.
Oh they could argue on Pavonis, and they most certainly would. Everywhere in fact. A most extraordinarily contentious lot they were. What was the sociology that would explain that? Hard to say. And in any case they had co-operated despite their bickering; it might have been only a temporary confluence of interests, but everything was temporary now with so many traditions broken or vanished, it left what John used to called the necessity of creation; and creation was hard. Not everyone was as good at creation as they were at complaining.
But they had certain capabilities now as a group, as a a civilization. The accumulated body of scientific knowledge was growing vast indeed, and that knowledge was giving them an array of powers that could scarcely be comprehended, even in outline, by any single individual. But powers they were, understood or not. Godlike powers, as Michel called them, though it was not necessary to exaggerate them or confuse the issue they were powers in the material world, real but constrained by reality. Which nevertheless might allow it looked to Sax as if they could if rightly applied make a decent human civilization after all. After all the many centuries of trying. And why not? Why not? Why not pitch the whole enterprise at the highest level possible? They could provide for everyone in an equitable way, they could cure disease, they could delay senescence until they lived for a thousand years, they could understand the universe from the Planck distance to the cosmic distance, from the Big Bang to the eskaton all this was possible, it was technically achievable. And as for those who felt that humanity needed the spur of suffering to make it great, well they could go out and find anew the tragedies that Sax was sure would never go away, things like lost love, betrayal by friends, death, bad results in the lab. Meanwhile the rest of them could continue the work of making a decent civilization. They could do it! It was amazing, really. They had reached that moment in history when one could say it was possible. Very hard to believe, actually; it made Sax suspicious; in physics one became immediately dubious when a situation appeared to be somehow extraordinary or unique. The odds were against that, it suggested that it was an artefact of perspective, one had to assume that things were more or less constant and that one lived in average times the so-called principle of mediocrity. Never a particularly attractive principle, Sax had thought; perhaps it only meant that justice had always been achievable; in any case, there it was, an extraordinary moment, right there outside his four windows, burnished under the light touch of the natural sun. Mars and its humans, free and powerful.
It was too much to grasp. It kept slipping out of his mind, then reoccurring to him, and surprised by joy he would exclaim, Ha! Ha! The taste of tomato soup and bread; Ha! The dusky purple of the twilight sky; Ha! The spectacle of the dashboard instrumentation, glowing faintly, reflected in the black windows; Ha! Ha! Ha! My oh my. He could drive anywhere he wanted to. No one told them what to do. He said that aloud to his darkened AI screen: No one tells us what to do! It was almost frightening. Vertiginous. Ka, the yonsei would say. Ka, supposedly the little red peoples name for Mars, from the Japanese ka, meaning fire. The same word existed in several other early languages as well, including proto-Indo-European; or so the linguists said.
Carefully he got in the big bed at the back of the compartment, in the hum of the rovers heating and electrical system, and he lay humming to himself under the thick coverlet that caught up his bodys heat so fast, and put his head on the pillow and looked out at the stars.
The next morning a high pressure system came in from the northwest, and the temperature rose to 262° K. He had driven down to five kilometres above the datum, and the exterior air pressure was 230 millibars. Not quite enough to breathe freely, so he pulled on one of the heated surface suits, then slipped a small air tank over his shoulders, and put its mask over his nose and mouth, and a pair of goggles over his eyes.
Even so, when he climbed out of the outer lock door and down the steps to the sand, the intense cold caused him to sniffle and tear up, to the point of impeding his vision. The whistle of the wind was loud, though his ears were inside the hood of his suit. The suits heater was up to the task, however, and with the rest of him warm, his face slowly got used to it.
He tightened the hoods drawstring and walked over the land. He stepped from flat stone to flat stone; here they were everywhere. He crouched often to inspect cracks, finding lichen and widely scattered specimens of other life: mosses, little tufts of sedge, grass. It was very windy. Exceptionally hard gusts slapped him four or five times a minute, with a steady gale between. This was a windy place much of the time, no doubt, with the atmosphere sliding south around the bulk of Tharsis in massed quantities. High pressure cells would dump a lot of their moisture at the start of this rise, on the western side; indeed at this moment the horizon to the west was obscured by a flat sea of cloud, merging with the land in the far distance, out there two or three kilometres lower in elevation, and perhaps sixty kilometres away.
Underfoot there were only bits of snow, filling some of the shaded crack systems and hollows. These snowbanks were so hard that he could jump up and down on them without leaving a mark. Windslab, partially melted and then refrozen. One scalloped slab cracked under his boots, and he found it was several centimetres thick. Under that it was powder, or granules. His fingers were cold, despite his heated gloves.
He stood again and wandered, mapless over the rock. Some of the deeper hollows contained ice pools. Around midday he descended into one of these and ate his lunch by the ice pool, lifting the air mask to take bites out of a grain and honey bar. Elevation 4-5 kilometres above the datum; air pressure 267 millibars. A high pressure system indeed. The sun was low in the northern sky, a bright dot surrounded by pewter.
The ice of the pool was clear in places, like little windows giving him a view of the black bottom. Elsewhere it was bubbled or cracked, or white with rime. The bank he sat on was a curve of gravel, with patches of brown soil and black dead vegetation lying on it in a miniature berm the high-water mark of the pond, apparently, a soil shore above the gravel one. The whole beach was no more than four metres long, one wide. The fine gravel was an umber colour, piebald umber or He would have to consult a colour chart. But not now.
The soil berm was dotted by pale green rosettes of tiny grass blades. Longer blades stood in clumps here and there. Most of the taller blades were dead, and light grey. Right next to the pond were patches of dark green succulent leaves, dark red at their edges. Where the green shaded into red was a colour he couldnt name, a dark lustrous brown stuffed somehow with both its constituent colours. He would have to call up a colour chart soon it seemed; lately when looking around outdoors he found that a colour chart came in handy about once a minute. Waxy almost-white flowers were tucked under some of these bi-coloured leaves. Further on lay some tangles, red-stalked, green-needled, like beached seaweed in miniature. Again that intermixture of red and green, right there in nature staring at him.
A distant wind-washed hum; perhaps the harping rocks, perhaps the buzz of insects. Black midges, bees in this air they would only have to sustain about 30 millibars of CO2, because there was so little partial pressure driving it into them, and at some point internal saturation was enough to hold any more out. For mammals that might not work so well. But they might be able to sustain 20 millibars, and with plant life flourishing all over the planets lower elevations, CO2 levels might drop to 20 millibars fairly soon; and then they could dispense with the air tanks and the facemasks. Set loose animals on Mars.
In the faint hum of the air he seemed to hear their voices, immanent or emergent, coming in the next great surge of viriditas. The hum of distant voices; the wind; the peace of this little pool on its rocky moor; the Nirgalish pleasure he took in the sharp cold Ann should see this, he murmured.
