up together with her, all inside an epiphany of Red Mars, free of Earth, living on the primal planet that had been and could be again.
She sat down. This time it was not Sax who rose to debate with her, as it had been so many times before. In fact he was cross-eyed with concentration, looking at her open-mouthed, in an amazement that she could not interpret. They stared at each other, the two of them, eyes locked; but what he was thinking she had no idea. She only knew she had caught his attention at last.
This time it was Nadia who rebutted her, Nadia her sister, arguing slowly and calmly for interaction with Earth, for intervention in the Terran situation. She spoke of the need to compromise, the need to engage, influence, transform. It was deeply contradictory, Ann thought; because they were weak, Nadia was saying, they could not afford to offend, and therefore they must change all Terran social reality.
‘But how!’ Ann cried. ‘When you have no fulcrum you can’t move a world! No fulcrum, no lever, no force—’
‘It isn’t just Earth,’ Nadia replied. ‘There are going to be other settlements in the solar system. Mercury, Luna, the big outer moons, the asteroids. We’ve got to be part of all that. As the original settlement, we’re the natural leader. An unbridged gravity well is just an obstruction to all that – a reduction in our ability to act, a reduction in our power.’
‘Getting in the way of progress,’ Ann said bitterly. ‘Think what Arkady would have said to that. No, look. We had a chance here to make something different. That was the whole point. We still have that chance. Everything that increases the space within which we can create a new society is a good thing. Everything that reduces our space is a bad thing. Think about it!’
Perhaps they did. But it made no difference. Any number of elements on Earth were sending up their arguments for the cable – arguments, threats, entreaties. They needed help down there. Any help. Art Randolph continued energetically lobbying for the cable on behalf of Praxis, which was looking to Ann as if it would become the next transitional authority, metanationalism in its latest manifestation or disguise.
But the natives were being won over by them slowly, intrigued by the possibility of ‘conquering Earth’, unaware of how impossible this was, incapable of imagining Earth’s vastness and immobility. One could tell them and tell them, but they would never be able to imagine it.
Finally it was time for an informal vote. It was representative voting, they had decided, one vote for each of the signatory groups to the Dorsa Brevia document, one vote also to all the interested parties that had arisen since then – new settlements in the outback, new political parties, associations, labs, companies, guerrilla bands, the several Red splinter groups. Before they started some generous naive soul even offered the First Hundred a vote, and everyone there laughed at the idea that the First Hundred might be able to vote the same way on anything. The generous soul, a young woman from Dorsa Brevia, then proposed that each of the First Hundred be given an individual vote, but this was turned down as endangering the tenuous grasp they had on representative governance. It would have made no difference anyway.
So they voted to allow the space elevator to remain standing, for the time being – and in the possession of UNTA, down to and including the Socket, without contestation. It was like King Canute deciding to declare the tide legal after all, but no one laughed except Ann. The other Reds were furious. Ownership of the Socket was still being actively contested, Dao objected loudly, the neighbourhood around it was vulnerable and could be taken, there was no reason to back off like this, they were only trying to sweep a problem under the rug because it was hard! But the majority were in agreement. The cable should remain.

Ann felt the old urge: escape. Tents and trains, people, the little Manhattan skyline of Sheffield against the south rim, the summit basalt all torn and flattened and paved over … There was a piste all the way around the rim, but the western side of the caldera was very nearly uninhabited. So Ann got in one of the smallest Red rovers, and drove around the rim counterclockwise, just inside the piste, until she came to a little meteorological station, where she parked the rover and went out through its lock, stiff in a walker that was much like the ones they had gone out in during the first years.
She was a kilometre or two away from the rim’s edge. She walked slowly east toward it, stumbling once or twice before she started to pay proper attention. The old lava on the flat expanse of the broad rim was smooth and dark in some places, rough and lighter in others. By the time she approached the edge she was in full areologist mode, doing a boulder ballet she could sustain all day, attuned to every knob and crack underfoot. And this was a good thing, because near the rim’s drop-off the land collapsed in a series of narrow curving ledges, the drops sometimes a step, sometimes taller than she was. And always the growing sense of empty air ahead, as the far side of the caldera and the rest of the great circle became visible. And then she was climbing down onto the last ledge, a bench only some five metres wide, with a curved back wall, shoulder-high: and below her dropped the great round chasm of Pavonis.
This caldera was one of the geological marvels of the solar system, a hole forty-five kilometres across and a full five kilometres deep, and almost perfectly regular in every way – circular, flat-floored, almost vertically walled – a perfect cylinder of space, cut into the volcano like a rock sampler’s coring. None of the other three big calderas even approached this simplicity of form; Ascraeus and Olympus were complicated palimpsests of overlapping rings, while the very broad, shallow caldera of Arsia was roughly circular, but shattered in every way. Pavonis alone was a regular cylinder: the Platonic ideal of a volcanic caldera.
Of course from this wonderful vantage point she now had, the horizontal stratification of the interior walls added a lot of irregular detail, rust and black and chocolate and umber bands indicating variations in the composition of the lava deposits; and some bands were harder than those above and below, so that there were many arcuate balconies lining the wall at different elevations – isolated curving benches, perched on the side of the immense rock throat, most never visited. And the floor so flat. The subsidence of the volcano’s magma chamber, located some one hundred and sixty kilometres below the mountain, had to have been unusually consistent; it had dropped in the same place every time. Ann wondered if it had been determined yet why that had been; if the magma chamber had been younger than the other big volcanoes, or smaller, or the lava more homogenous … Probably someone had investigated the phenomenon; no doubt she could look it up on the wrist. She tapped out the code for the Journal of Areological Studies, typed in Pavonis: ‘Evidence of Strombolian explosive activity found in west Tharsis clasts’. ‘Radial ridges in caldera and concentric graben outside the rim suggest late subsidence of the summit’. She had just crossed some of those graben. ‘Release of juvenile volatiles into atmosphere calculated by radiometric dating of Lastflow marks’.
She clicked off the wristpad. She no longer kept up with all the latest areology, she hadn’t for years. Even reading the abstracts would have taken far more time than she had. And of course a lot of areology had been badly compromised by the terraforming project. Scientists working for the metanats had concentrated on resource exploration and evaluation, and had found signs of ancient oceans, of the early warm wet atmosphere, possibly even of ancient life; on the other hand radical Red scientists had warned of increased seismic activity, rapid subsidence, mass wasting, and the disappearance of even a single surface sample left in its primal condition. Political stress had skewed nearly everything written about Mars in the past hundred years. The Journal was the only publication Ann knew of which tried to publish papers delimiting their inquiries very strictly to reporting areology in the pure sense, concentrating on what had happened in the five billion years of solitude; it was the only publication Ann still read, or at least glanced at, looking through the titles and some of the abstracts, and the editorial material at the front; once or twice she had even sent in a letter concerning some detail or other, which they had printed without fanfare.
