A Shot in the Dark by Deborah L. Davitt (Analog, January-February 2021)1 has as its protagonist Dominic Vadas, a solo prospector who works on Titania (a moon of Uranus), humanity’s farthest away outpost. The only company this committed loner has is an AI called Enara, who interrupts his work to tell him that there is an incoming message from their bosses, the UN Space Control Agency—they ask Vadas to fuel up his ship and intercept an exo-solar object that has entered the solar system. There is then further disruption to Vadas’s routine as he prepares to depart, when he gets a message from a woman claiming to be his daughter. After the ship gets underway Vadas sends a reply that describes his short relationship with the woman’s mother and how it ended. Vadas later learns that he is not only a father, but a grandfather too.
The rest of the story sees Vadas receive further messages from both the woman and UNSCA as he approaches the exo-solar object. As Vadas gets closer to the object it soon becomes apparent that it is (spoiler) a spaceship of alien construction and, after some cautionary hand wringing from UNSCA, he goes EVA to explore. Then, after an external and internal examination of the object, Vadas takes samples back to the ship and comes to the conclusion about what the alien object is:
Back on the Resolution, he examined his finds in the airless vacuum of the cargo bay, using a microscope. UNSCA had yet to call in to scold him, for which he was grateful. They might not, once he sent them his current results. “Bacteria,” he finally assessed.
“Some of them might still be viable,” Enara noted. “Some have formed endospores. Control will likely assess this as a weapon of biological warfare between long-gone civilizations.”
Dominic thought about it as he stripped out of his EVA suit. Thought about his daughter, whom he’d never met. The grandson he hadn’t known he had. A shot through the dark of time, a chance connection of genetic material spanning worlds. Like all life, really. “Panspermia,” he said out loud, sitting down by the controls. “That’s what this is. Not a weapon. I’d be willing to bet that whoever they were, they sent these out by the thousands. Hoping that someday, they’d land on a planet with decent temperatures and at least the start of an atmosphere. And when they did, they’d eject their payload and start life on that planet. And that life would adapt to its surroundings, and adapt its surroundings to it. Slowly. Very slowly.” p .51
After this intuition the object comes to life, deploys solar sails, and starts heading towards Uranus for a gravity assist that will slingshot it further into our solar system. UNSCA greets this news with alarm and wants him to boost the craft out of the system, but Vadas sends a broadcast stating that humanity should pause and give the object a chance before treating it as hostile—i.e. be open to possibility. Then he asks his daughter for photos of his grandson.
This is a solid piece that successfully combines an interesting character study, a relationship dilemma, and an interesting SF story.
