over UHF stations on the ground. In her bubble helmet she had a hundred and eighty degree vision, and she had a great sense of freedom. She knew that when she returned to the cabin, after the EVA, it would seem constricting, absurdly confining.

      As she gazed at Earth – at all of humanity, save for the six on orbit with her on Columbia and a handful on Station – she felt some of the tension drain out of her, as if it was being drawn up to the planet. She felt lifted out of the web of concerns that dominated her life: the difficulties of her career, the frustrating pace of the space program, her unsatisfactory relationship with Jackie, her daughter, the blizzard of hassles that made up every day, mail and balky technology and her car and her apartment and accounts she had to pay and …

      No wonder people get hooked on this, she thought.

      ‘Okay, EV2, Houston. Coming up to your three hundred feet limit.’

      ‘Copy that.’ Three hundred feet was as far as she could allow herself to travel. Moving away from Columbia, Benacerraf was actually entering a slightly different orbit. If she went much further, return to the orbiter would become a full-scale rendezvous, a matter of complex course correction manoeuvres.

      She passed out of the shadow of the wing, and into sunlight; her EMU seemed to glow.

      ‘I see your light, Paula,’ Lamb called.

      ‘I’m pleased to hear it, Tom.’

      ‘EV2, Houston. Confirming your ground-to-MMU direct link is operational.’

      ‘Thank you.’

      ‘And your transponder beacon is functioning.’

      ‘Copy that.’

      ‘EV2, Houston. You have a lot of green-eyed people watching you; looks like you’re having a lot of fun.’

      ‘Sure. This is working very nicely. Ah, I’m glad I’ve got old Brer Rabbit out here with me, out in the briar patch where he belongs.’

      She heard Lamb chuckle at that, back in the payload bay. She was aping the first words he’d spoken on the Moon.

      

      Most astronauts got off the active list after four or five flights. They moved out into industry, or up into some kind of program management position within NASA. What kind of man was it who would keep on subjecting himself – and his family – to the grind of training, two years for every Shuttle mission, the enormous dangers of the missions themselves, flight after flight, year after year, logging up the spaceflight hours well into his sixties, endlessly defying the survival odds?

      She’d even formulated the thought that maybe Lamb wasn’t actually good for anything else. To stay in the office you had to resist promotion, after all. You had to demonstrate sustained mediocrity. John Young, the other great surviving Moonwalker, had been taken off the active roster when he’d been so vocal in criticizing NASA safety procedures after Challenger.

      Besides, all that ancient astronaut-as-Cold Warrior garbage from the 1960s, which still clung around NASA, just did not cut any ice with Benacerraf. It had nothing to do with the future of space travel as she saw it, which could only be about a steady, logical and gradual expansion of the space frontier, beyond Earth. Or even with the actions required of NASA, the space agency, to survive in a future of decreasing funding, increasing irrationality, a growing sense of military threat from China and elsewhere which was causing the ancient Cold Warriors to come rearing from their bunkers once more …

      It might take all of her career to build the Space Station; she might never get to see another human being walk on the Moon. Well, that was fine by her. Space was a damn difficult place to work.

      But as long as Lamb, and one or two others, still hung around, you still had the hero-centered distortion of the whole organization. As if everything that had happened after 1972 had been a long, dull coda. Even the Mission Controllers and their backroom staff were mostly aviation people of some kind, she was finding; and a startling number of the controllers – who were supposed to be there as specialist engineers or scientists – would apply to join the astronaut office at every recruitment round, regular as clockwork.

      … But all that was before she’d begun to train with Lamb for this flight, STS-143. Before she’d sat with him through hours of sims, observed his prowess at the antique complexities of the Shuttle system, seen him demonstrate his calm control in the abort options. Tom Lamb could handle things, she’d come to realize. His old-fashioned jock bull hid a central, deep-rooted competence.

      As she’d been strapped into Columbia’s flight deck for her first launch, she’d been grateful for Lamb’s calm voice, responding to the ground. If anyone could get her home alive, it would be Tom Lamb.

      And anyhow, now she was up here, she started to see his point of view.

      

      She swung herself around, and faced back down into the payload bay. She blipped her left-hand controller to slow her rotation.

      Columbia’s cabin was above her head, the tail section below her feet. The starboard wing was in the shadow of the sun; the big Stars and Stripes on the port wing was obscured by the open bay doors. Her eyes were dark-adapted to Earthlight, so she could see no stars beyond the orbiter. Columbia was like a complex toy, brilliant white and silver, set against complete blackness.

      At first glance Columbia looked faintly ridiculous: that fat, boxy body, the patchy coloration of the thermal protection system, the snub nose, those thick wings and that huge tail: Columbia was like an airliner stranded in space, its aerodynamic surfaces useless in vacuum. Columbia, the first of the five Shuttle orbiters built – and so the most primitive – weighed all of a hundred and eighty thousand pounds dry. You had to haul all that mass up into orbit, and back down again, every flight, to deliver just fifty thousand pounds of payload to orbit.

      And after thirty flights Columbia was showing her age. She could see how the white-painted hull was scarred and battered, the slight discolorations between the tiles, the scuffs on the windows that sparkled in the sunlight, the stains on the thermal fabric lining the payload bay.

      But all of that seemed to fade from her awareness, as she saw the orbiter drifting serenely against the blackness of space. Bizarrely, Columbia looked as if she belonged up here.

      The Shuttle system was the technology of the 1970s, still flying in the ’oos, with the hard wisdom of the intervening years built into it. And, realistically, no replacement system in sight. Columbia was fresh paint over rusty, obsolescent technology. But somehow, up here, she was able to make out the 1960s von Braun dream of spaceplanes which the orbiter embodied.

      Her throat hurt. Damn it, she felt as if she was going to cry.

      The light around her changed. The shadow of the starboard wing was growing longer. Columbia was passing into another forty-five minute night.

      ‘… Hey, Paula,’ Tom Lamb said now. ‘Scuttlebutt from home. Some double-dome from JPL is saying he’s found life on Titan.’

      ‘Really?’

      ‘So they say. Nice place to hear about it, huh.’

      ‘Yes,’ she said.

      … She turned again, to face Earth.

      At the rim of the planet she could see the airglow layer, a bright layer of oxygen radiating at the top of the atmosphere, like a false horizon. The lights of cities, strung along the coasts of the land, looked like streetlights scattered along a road. There was a thunderstorm over central Africa, and she could see lightning sparking constantly, over cloud systems spanning thousands of miles. The lightning propagated through the clouds like a living thing, growing and spreading; its glow shone from beneath the layer of cloud, and she could see three-dimensional structure within the cloud, edges and swirls of purple.

      The leading edges of Columbia glowed, a faint orange, in an aura a few inches thick. The glow came from a thin hail of atoms of atomic oxygen, interacting with the orbiter’s surfaces.

      Even here, she thought, they were
