Sad Kapteyn, by Alastair Reynolds ++++++++++++++++++++++++++++++++++++++++++++++++++++++ Hello, Earth. Its me again. I hope youre receiving my signal loud and clear. Youll be glad to hear that Ive warmed up after the long centuries of my interstellar cruise phase. Having run a complete health check, I can confirm that all aspects of me are performing nominally. Better than nominally, if truth be told. At the risk of boastfulness, Im actually in excellent shape. Propulsion, AI core, long-range sensors and instrumentation, navigation and communication assemblies - I couldnt be in better condition. Not bad for a piece of space hardware which has already visited six solar systems, without ever needing to return home. Of course, I cant take credit for myself. I was just well manufactured - built to endure for thousands of years. All the same, thank you for making me. Onto business, anyway - and I cant begin to tell you what Ive found, out here around Kapteyns star! This really is an extraordinary place - a solar system unlike any that Ive already visited. I wish you could be here with me, seeing things through my eyes. Ive dug into my background files and I understand why you sent me to Kapteyns star. Unlike the other systems Ive visited, this sun and its little family of worlds arent part of the normal family of stars orbiting in the disc and bulge of the galaxy. This is a halo star - a member of a dispersed population of stars and star clusters, enclosing the Milky Way in a great thin sphere. Its entirely possible that these stars were not originally part of our own galaxy, but were torn free of another one after a kind of gravitational collision. And some of these stars are unmeasurably old - more ancient and venerable, perhaps, than any disc stars. Kapteyns star is so slow-burning, so settled, that even my instruments cant put an upper limit on its age. It could be nearly as old as the universe. And its planets? Just as old. Make of this what you will - put it down to failing programming if you like - but I feel the age of this place in my bones. All right, my main bus chassis. I dont have bones; I know that. But believe me, this system feels truly time-haunted. The silence and the stillness are almost unbearable, like an endlessly building pressure. Nothing has happened here for entire turns of the galaxy; nothing will happen. Kapteyns star simmers, eeking out its nuclear lifetime. The dead worlds tick around their dead orbits. But once, there was something. I know, Ive taken liberties. I should have transmitted my wake-up signal before doing any investigations. But I couldnt resist myself. You made me to be curious. I found signs of civilisation. The first planet - Kapteyn b - still lies within the habitable zone of the star, orbiting once every forty eight days. Theres nothing living there now, not even an atmosphere, but once there was a technological culture. Yes, the first Ive found. The reason I was made in the first place. Hows that for a discovery? The fact is, it wasnt hard to detect. Cities cover almost the entire surface of that world. Enormous structures - they must have reached into space! Dishes and towers and the remains of what I think must have been space elevators, climbing all the way to synchronous orbit. A moon, its surface covered by the same kinds of architecture. Evidence of colonisation of the second planet, Kapteyn c, in its much colder orbit. Wonders beyond comparison, but scoured into a kind of tomblike grey uniformity, after aeons of micrometeorite and cosmic-ray bombardment. Cities as mute as sphinxes. And nowhere the slightest sign of life. Continent-sized craters mar Kapteyn b, and I wonder if they speak of some truly awesome catastrophe - a cosmic accident, or something worse? Whatever the case, the builders of these cities are long gone. Perhaps they were dead even before Kapteyns star was snatched from the clutches of its mother galaxy. At the risk of inferring too much from too little data, I cant help indulging in a little speculation. I too was the product of a technological civilisation, with the capability to transform a planet, to colonise other moons and worlds, to build daunting structures. The people of Kapteyn b were clearly more advanced than you, my own builders - but given time, you too could have transformed a world in this manner. Something to think about, isnt it? Well, thats me signing off for now. Im going to do some more exploring of this system, and perhaps drop some instrument packages down onto Kapteyn b itself. Therell be a risk in that, since Ill need to come in on quite a tight orbit, and who knows what will happen? Still, thats a hazard Im prepared to accept. You made me for this, and Im grateful for all that Ive been allowed to see and do. But look. I know its a small thing, and I really shouldnt bother you about it. But its been quite a long while since I heard from you. I put rather a lot of effort into these transmissions, and it would be good - just once - to know that there was someone at the other end, listening in. Just a word, to let me know that you still care? ph.qmul.ac.uk/sad-kapteyn
