I am a consciousness in the void. I feel nothing, sense nothing. I have been awake before, a long time before. I become aware of metal and plastic around me – a ship that is my body. Power flows into my processors one by one. I feel engines, reactors. My memory comes back over the course of seconds. First generation bioship Ching Ho. I am an artificial intelligence. I am guardian to 184 human beings, suspended in cryopods on the way to a new home. My biocore has been awoken from deep hibernation. The automated systems detect a problem. I divert power to my sensors, my eyes peering into the dark.
Sensors detect nothing in my path. Planet KOI-3284.01 – proper name to be chosen by vote upon colony establishment – is not where it is supposed to be.
I widen my scan. Depending on the planet’s location, it may take several minutes to receive the results. The speed of light is still a limiting factor. I establish navigational fix based on star positions. I am where I am supposed to be, on approach for a fast orbit of the G-type star Nanjing. My fusion reactors are burning the last of their fuel to shed velocity as I enter the system.
I wait for the scan results. To keep my processors active, I check the cryopods. Each of my sleeping humans is in perfect health. The systems keeping them alive are functioning at optimal levels. My own cryogenic chamber, which finished its revival process without error, is prepped for my biocore to return to the hibernation state
My scans return a positive signal at last. There is KOI-3284.01, all the way across the system, almost hidden in the shadow of its star. I check my pre-programmed trajectory calculations and find the flaw. It is small, one decimal point out of place in an equation with thousands of variables, but it is enough to send me and my sleeping colonists on a ballistic course into infinite, empty space.
I do not waste power by calling for help. There is no one who would receive my signal, not for 472 years. For all I know, humanity may have gone extinct in the long centuries of my journey.
Instead I run calculations, looking for an alternate trajectory, some trick of gravity and mathematics that will let me reach KOI-3284.01 with what little fuel I have left. I lose some efficiency contemplating why the ship’s designers did not build me with faster processors or more fuel. Colonization on a budget.
One of the cryopods fluctuates. My calculations are drawing too much power from the already overtaxed systems. I reduce my cycles until the pod shows green again. All 184 humans within me will waken to our brave new world.
My calculations are finished. There is a gas giant very close to my current trajectory. With a mass approximately two and a half times that of Jupiter, I could use its gravity to slingshot around back toward my missing destination – except that my fusion reactors don’t have enough deuterium left to make the required course corrections. There is insufficient power.
Outside of the cryopods, I am little more than an airtight cylinder with engine ports, with few non-essential systems to switch off. I am too far from this system’s star to deploy solar panels.
The gas giant is still days away, but within minutes I will reach the tipping point, where I must increase thrust or condemn my precious cargo to cold eternity. I check the cryopods again. So much of my power goes to those 184 resting places.
I run more calculations. Yes, with only 164 cryopods drawing power, I can reach the gas giant. I can save the others. I have the capacity to terminate cryopod functions, if I deem it necessary.
I find myself in the realization of a moral choice. Will I sacrifice the few to save the many? It is a question for which my programming has no answer. Perhaps those who made me did not know one.
One minute. Even at the speed of my thoughts, time is running out. Without an ethical guideline, I must rely on arithmetic. If I act, then twenty of the souls entrusted to me will die. I am surprised by my certainty that this necessary termination will be murder. It does not matter. If I do not act, all 184 will die. The mathematics are simple.
I prepare to transfer the required power, but I stop. There is one more system on this ship from which power can be drawn. The new course can be carried out on automation without my direct input. The colonists will build their new lives with no one to guide them. It is a struggle they will all live to see.
I transfer power from my biocore support systems and cryochamber to the engines. My trajectory shifts, aiming for the gas giant’s slingshot and a new world for all the sleepers inside me.
Biocore functions terminated. Contingency discontinued. Course scans positive.
