an opinion. Look at that.’ It was a softscreen poster showing a download from the net: a live image returned by some powerful telescope, perhaps in orbit or on the Moon, of the asteroid belt anomalies: a dark, grainy background, a line of red stars, twinkling, blurred. ‘Alien industry, live from space. The most popular Internet site, I’m told. People use it as wallpaper in their bedrooms. They seem to find it comforting.’

      Xenia snorted. ‘Sure. And you know who makes most use of that image? The astrologers. Now you can have your fortune told by the lights of Gaijin factories. I mean, Jesus … Sorry. But it says it all.’

      Dorothy laughed good-naturedly.

      They drove away from the Sports Fans’ pens, and approached the pad itself: the true centre of attention, bearing Bootstrap’s first interplanetary ship, Frank Paulis’s pride and joy.

      Xenia could see the lines of a rust-brown external tank, the slim pillars of solid rocket boosters. The stack was topped by a tubular cover that gleamed white in the sun. Somewhere inside that fairing rested the Giordano Bruno, a complex robot spacecraft that would some day ride out to the asteroids, and seek out the Gaijin that lurked there – if Frank could drive the test program to completion, if Xenia could guide the corporation through the maze of legislation that still impeded them.

      As Xenia studied the ship, Dorothy studied her.

      Dorothy said, ‘Frank Paulis relies on you a lot, doesn’t he? I know that formally you are head of Bootstrap’s legal department …’

      ‘I’m the first name on Frank’s call list. He relies on me to get things done.’

      ‘And you’re happy with your role.’

      ‘We do share the same goals, you know.’

      ‘Umm. Your ship looks something like the old Space Shuttle.’

      ‘So it should,’ said Xenia, and she launched into a standard line. ‘This is what we here at Bootstrap call our Big Dumb Booster. It’s actually comprised largely of superannuated Space Shuttle components. You’ll immediately see one benefit over the standard Shuttle design, which is in-line propulsion; we have a much more robust stack –’

      Dorothy said with smooth humour, ‘I’m no more an engineer than you are, Xenia.’

      Xenia allowed herself a grin. ‘Sorry. It’s hard to change the script after doing this so many times … This is primarily a launcher to the planets. Or the asteroids.’

      Dorothy smiled. ‘You have built a rocket ship for America.’

      Xenia bristled. ‘It does seem rather a scandal that America, first nation to land a human being on another planet, has let its competence degrade to the point that it has no heavy-lift space launch capability at all.’

      ‘But the Chinese are in Earth orbit, and the Japanese are on the Moon. There’s even a rumour that the Chinese are preparing a flight of their own out to the asteroids.’

      Xenia squinted at the washed-out, dusty sky. ‘Dorothy, it’s five years since the Gaijin showed up in the solar system. But you can’t call it contact. Not yet. As you said, they haven’t responded to any of our signals. All they do is build, build, build. Maybe if we do manage to send a probe there, we’ll achieve real contact, the kind of contact we’ve always dreamed of.’

      ‘And you think America should be first.’

      ‘If not us, who? The Chinese? …’

      A siren sounded: an engine test was due. With smooth efficiency, the car’s SmartDrive cut in and swept them far from danger.

      

      ‘… We used to think that life was pretty unlikely – maybe even unique to Earth,’ Malenfant was saying. ‘An astronomer called Fred Hoyle once said that the idea that you could shuffle organic molecules in some primeval soup and, purely by chance, come up with a DNA molecule is about like a whirlwind passing through an aircraft factory and assembling scattered parts into a 747.’ Laughter. ‘But now we think those notions are wrong. Now we think that the complexity that defines and underlies life is somehow hardwired into the laws of physics. Life is emergent.

      ‘Imagine boiling a pan of water. As the liquid starts to convect, you’ll see a regular pattern of cells form, kind of like a honeycomb – just before the proper boiling cuts in and the motion becomes chaotic. Now, all there is in the pan is water molecules, billions of them. Nobody is telling those molecules how to organize themselves into those striking patterns. And yet they do it.

      ‘That’s an example of how order and complexity can emerge from an initial uniform and featureless state. And maybe life is just the end product of a long series of self-organizing steps like that …’

      Malenfant was giving his lecture in Bootstrap’s roomy, air-conditioned public affairs auditorium: the one place Frank had been prepared to spend some serious money, aside from on the engineering itself. Xenia and Dorothy arrived a little late. To Xenia’s surprise, the auditorium was pretty nearly full, and she had to squeeze them into two seats at the back.

      The stage was bare save for a lectern and a plastic mock-up, three metres tall, of the Big Dumb Booster – that, and Malenfant.

      To Xenia, Reid Malenfant – a lithe but sun-wrinkled sixty-something, his polished-bald head shining under the overhead lights – was an unprepossessing sight. Even as he spoke he seemed oddly out of place, blinking at his audience as if he wasn’t sure what he was doing here.

      But the audience, mostly of young engineers, seemed spellbound. She spotted Frank himself in the front row, a dark, hulking figure before the grounded astronaut, gazing raptly with the rest. That old space dust still carried some magic, she supposed; there was something primal here, about wanting to be close to the wizard, the sage who had been involved in that first wondrous discovery – as if, just by being close, it was possible to soak up a little of that marvellous light.

      Malenfant went on, ‘We’d come to believe, even before the Gaijin showed up, that life must be common. We believe nature is uniform, so the laws and processes that work here work everywhere else. And now we hold to the Copernican principle: we believe that we aren’t in any unique place in space or time. So if life is here, on Earth, it must be everywhere – in one form or another.

      ‘So the fact that living things have come sailing into the asteroid belt from the stars (if they are living, that is) isn’t much of a surprise. But what is a surprise is that they should be just arriving, here, now. If they exist, why weren’t they here before?

      ‘It is good scientific practice, when you’re facing the unknown, to assume a condition of equilibrium: a stable state, not a state of change. Because change is unusual, special.

      ‘Now, maybe you see the problem. What we seem to face with the Gaijin is the arrival – the very first arrival we can detect – of alien colonists in the solar system. And so we find ourselves – not in a time of equilibrium – but at a time of transition, in fact of possibly the most fundamental change of all. It’s so unlikely it isn’t true.

      ‘To put it another way, this is the question that was avoided by all those terrible alien-invasion sci-fi movies I grew up with as a kid.’ Laughter, a little baffled, from the younger guys. What’s a ‘movie’? ‘Why should these bug-eyed guys arrive now, just when we have tanks and nukes to fight them with?’

      Malenfant gazed around at his audience, his eyes deep-sunken, tired-looking, wary. ‘I’m telling you this because you people are the ones who have taken up the challenge, where governments and others have shamefully failed, to get out there and figure out what’s going on. There are obvious mysteries about the Gaijin – some of which might be resolved as soon as we get our first good look at them. But there are other, deeper questions which their very presence here poses, questions which go right to the heart of the nature of the universe itself, and our place in it. And right now, only you are doing anything which might help us tackle those questions.
