reach should exceed his grasp, or what’s a heaven for?”
    Alexander Ignatiev did not believe in heaven. But he thought he knew what hell was like.

    As he entered his quarters he saw that at least the cleaning robots had finished and left; the sitting room looked almost tidy. And he was alone.
    The expedition to Gliese 581 had left Earth with tremendous fanfare. The first human mission to another star! Gliese 581 was a very ordinary star in most respects: a dim red dwarf, barely one-third of the Sun’s mass. The galaxy was studded with such stars. But Gliese 581 was unusual in one supremely interesting way: it possessed an entourage of half a dozen planets. Most of them were gas giants, bloated conglomerates of hydrogen and helium. But a couple of them were rocky worlds, somewhat like Earth. And one of those—Gliese 581g—orbited at just the right “Goldilocks” distance from its parent star to be able to have liquid water on its surface.
    Liquid water meant life. In the solar system, wherever liquid water existed, life existed. In the permafrost beneath the frozen rust-red surface of Mars, in the ice-covered seas of the moons of Jupiter and Saturn, in massive Jupiter’s planet-girdling ocean: wherever liquid water had been found, life was found with it.
    Half a dozen robotic probes confirmed that liquid water actually did exist on the surface of Gliese 581g, but they found no evidence of life. Not an amoeba, not even a bacterium. But that didn’t deter the scientific hierarchy. Robots are terribly limited, they proclaimed. We must send human scientists to Gliese 581g to search for life there, scientists of all types; men and women who will sacrifice half their lives to the search for life beyond the solar system.
    Ignatiev was picked to sacrifice the last half of his life. He knew he would never see Earth again, and he told himself that he didn’t care. There was nothing on Earth that interested him anymore, not since Sonya’s death. But he wanted to find something, to make an impact, to keep his name alive after he was gone.
    Most of the two hundred scientists, engineers and technicians aboard Sagan were sleeping away the decades of the flight in cryonic suspension. They would be revived once the scoopship arrived at Gliese 581’s vicinity. Only a dozen were awake during the flight, assigned to monitor the ship’s systems, ready to make corrections or repairs if necessary.
    The ship was highly automated, of course. The human crew was a backup, a concession to human vanity unwilling to hand the operation of the ship completely to electronic and mechanical devices. Human egos feared fully autonomous machines. Thus a dozen human lives were sacrificed to spend five decades waiting for the machines to fail.
    They hadn’t failed so far. From the fusion power plant deep in the ship’s core to the tenuous magnetic scoop stretching a thousand kilometers in front of the ship, all the systems worked perfectly well. When a minor malfunction arose, the ship’s machines repaired themselves, under the watchful direction of the master AI program. Even the AI system’s computer program ran flawlessly, to Ignatiev’s utter frustration. It beat him at chess with depressing regularity.
    In addition to the meaningless title of senior executive, Alexander Ignatiev had a specific technical task aboard the starship. His assignment was to monitor the electromagnetic funnel that scooped in hydrogen from the thin interstellar medium to feed the ship’s nuclear fusion engine. Every day he faithfully checked the gauges and display screens in the ship’s command center, reminding himself each time that the practice of physics always comes down to reading a goddamned dial.
    The funnel operated flawlessly. A huge gossamer web of hair-thin superconducting wires, it created an invisible magnetic field that spread out before the starship like a thousand-kilometer-wide scoop, gathering in the hydrogen atoms floating
