I do have a huge collection of video games. I have every piece of software that was available when we built the ship. I’m sure they can keep me busy for a while.

I check the Taumoeba farms. All ten of them are doing just fine. I feed them Astrophage from time to time, just to keep them healthy and breeding. The farms emulate Venus’s atmosphere, so as the generations of Taumoeba go by, they’ll get even better at Venusian life. After four years of this, by the time I drop them off at the planet, they’ll be well suited for it.

And yes, I’ve already decided I’ll drop them off. Why not?

I have no idea what kind of world I’ll be returning to. Thirteen years have passed on Earth since I left, and they’ll experience another thirteen before I get back. Twenty-six years. All my students will be adults. I hope they all survive. But I have to admit… some probably won’t. I try not to dwell.

Anyway, once I get back to my solar system, I may as well swing by Venus and drop off the Taumoeba. Not sure how I’ll seed it, but I have a few ideas. The simplest is just to wad up a ball of Taumoeba-infested Astrophage and throw it at Venus. The Astrophage will absorb the heat of reentry and the Taumoeba will be released into the wild. Then they’ll have a field day. Venus must be Astrophage-central by now, and lord knows Taumoeba can get right to work once they find their prey.

I check my food stores. I’m still on schedule. I have another three months of real, edible food packs left, and then it’ll be coma slurry from then on.

I’m reluctant to go back into a coma. I’ve got the genes to survive it, but so did Yáo and Ilyukhina. Why risk death if I don’t have to?

Also, I can’t be 100 percent sure I correctly reprogrammed the course navigation. I think it’s right, and whenever I spot-check, I’m still on course toward home. But what if something goes wrong while I’m in a coma? What if I wake up and I missed the solar system by a light-year?

But between isolation, loneliness, and disgusting food, I may be willing to take those risks eventually. We’ll see.

Speaking of loneliness, my thoughts turn back to Rocky. My only friend now. Seriously. He’s my only friend. I didn’t have much of a social life back when things were normal. Sometimes I’d grab dinner with other faculty and staff at the school. I’d have the occasional Saturday-night beer with old college friends. But thanks to time dilation, when I get home all those folks will be a generation older than me.
