off the tap and leaves us coasting. The comet swells in our sights, a frozen enigma sweeping its signal across the sky like a lighthouse beam. We bring rudimentary senses to bear and stare it down on a thousand wavelengths.
We've lived for this moment.
We see an erratic wobble that speaks of recent collisions. We see scars—smooth icy expanses where once-acned skin has liquefied and refrozen, far too recently for the insignificant sun at our backs to be any kind of suspect.
We see an astronomical impossibility: a comet with a heart of refined iron.
Burns-Caufield sings as we glide past. Not to us; it ignores our passage as it ignored our approach. It sings to someone else entirely. Perhaps we'll meet that audience some day. Perhaps they're waiting in the desolate wastelands ahead of us. Mission Control flips us onto our backs, keeps us fixed on target past any realistic hope of acquisition. They send last-ditch instructions, squeeze our fading signals for every last bit among the static. I can sense their frustration, their reluctance to let us go; once or twice, we're even asked if some judicious mix of thrust and gravity might let us linger here a bit longer.
But deceleration is for pansies. We're headed for the stars .
Bye, Burnsie. Bye, Mission Control. Bye, Sol.
See you at heat death.

Warily, we close on target.
There are three of us in the second wave—slower than our predecessors, yes, but still so much faster than anything flesh-constrained. We are weighed down by payloads which make us virtually omniscient. We see on every wavelength, from radio to string. Our autonomous microprobes measure everything our masters anticipated; tiny onboard assembly lines can build tools from the atoms up, to assess the things they did not. Atoms, scavenged from where we are, join with ions beamed from where we were: thrust and materiel accumulate in our bellies.
This extra mass has slowed us, but midpoint braking maneuvers have slowed us even more. The last half of this journey has been a constant fight against momentum from the first. It is not an efficient way to travel. In less-hurried times we would have built early to some optimal speed, perhaps slung around a convenient planet for a little extra oomph , coasted most of the way. But time is pressing, so we burn at both ends. We must reach our destination; we cannot afford to pass it by, cannot afford the kamikaze exuberance of the first wave. They merely glimpsed the lay of the land. We must map it down to the motes.
We must be more responsible .
Now, slowing towards orbit, we see everything they saw and more. We see the scabs, and the impossible iron core. We hear the singing. And there, just beneath the comet's frozen surface, we see structure : an infiltration of architecture into geology. We are not yet close enough to squint, and radar is too long in the tooth for fine detail. But we are smart, and there are three of us, widely separated in space. The wavelengths of three radar sources can be calibrated to interfere at some predetermined point of convergence—and those tripartite echoes, hologramatically remixed, will increase resolution by a factor of twenty-seven.
Burns-Caulfield stops singing the moment we put our plan into action. In the next instant I go blind.
It's a temporary aberration, a reflexive amping of filters to compensate for the overload. My arrays are back online in seconds, diagnostics green within and without. I reach out to the others, confirm identical experiences, identical recoveries. We are all still fully functional, unless the sudden increase in ambient ion density is some kind of sensory artefact. We are ready to continue our investigation of Burns-Caulfield.
The only real problem is that Burns-Caulfield seems to have disappeared...
