Time's Eye by Arthur C. Clarke, Stephen Baxter

radio project, by comparison, was aimed at establishing communications that could enable them to survive; what use were all these images? Kolya didn’t feel the need to justify himself. There was surely nobody else in a position to do it—and Earth, he felt, deserved a witness to its metamorphosis.
    And besides, as far as he knew, his wife and boys were gone. If that were true, then what was the point of
anything
they did?
    The climate seemed restless: great low pressure systems prowled the oceans, and pushed their way toward the land, spinning off huge electrical storms. Seen from space the storms were wonders, with lightning flickering and branching between the clouds, releasing chain reactions that could span a continent. And at the equator clouds stacked up in great heaps that seemed to be straining toward him, and sometimes he imagined the
Soyuz
might plunge into those thunderheads. Perhaps the sea and the air had been as churned up as the land. As the days wore by the seeing slowly worsened. But, oddly, the increasing obscurity made him feel better about his situation—as if he was a child, able to believe that the badness had gone away if he couldn’t see it.
    When it got too hard to bear Kolya would turn to his lemon tree. This tree, bonsai small, had been the subject of one of his experiments on the Station. After the first day in the
Soyuz
he had dug it out of its packaging and now kept it in the little space under his seat. One day, aboard great liners sailing between the worlds, people would have grown fruit in space, and Kolya might have been remembered as a pioneer in a new way of cultivating life beyond the Earth itself. Those possibilities were all gone now, it seemed, but the little tree remained. He would hold it up to the sunlight that streamed in through the windows, and sprinkle precious water from his mouth onto its small leaves. If he rubbed the leaves between his fingers, he could smell their tang, and he was reminded of home.
    The strangeness of the transformed world beneath its pond of air contrasted with the cozy kitchen-like familiarity of the
Soyuz
, so that it was as if what they saw beyond the windows was all a light show, not real at all.
    About midday on that tenth day Sable stuck her head, upside down, out of the hatch to the living compartment. “Unless you two have another appointment,” she said, “I think we need to talk.”
    The others huddled in their couches, under thin silvered survival blankets, avoiding each other’s eyes. Sable twisted into her place.
    “We’re running out,” Sable said bluntly. “We’re running out of food, and water, and air and wet wipes, and I’m out of tampons.”
    Musa said, “But the situation on the ground has not normalized—”
    “Oh, come on, Musa,” Sable snapped. “Isn’t it obvious that the situation never is going to
normalize
? Whatever has happened to the Earth—well, it looks as if it’s stuck that way. And we are stuck with it.”
    “We can’t land,” Kolya said quietly. “We have no ground support.”
    “Technically,” Musa said, “we could handle the reentry ourselves. The
Soyuz
’s automated systems—”
    “Yeah,” Sable said, “this is the Little Spaceship That Could, right?”
    “There will be no retrieval,” Kolya insisted. “No helicopters, no medics. We have all been in space for three months, plus ten unexpected days. We will be as weak as kittens. We may not even be able to get out of the descent compartment.”
    “Then,” Musa growled, “we must ensure we land somewhere close to people—any people—and throw ourselves on their mercy.”
    “It’s not a good prospect,” Sable said, “but what choice do we have? To stay on orbit? Is that what you want, Kolya? To sit up here taking pictures until your tongue is stuck to the roof of your mouth?”
    Kolya said, “It might be a better end than whatever awaits us down there.” At least he was in a familiar environment, here in this
