That’s how the Big Three – Heinlein, Asimov, and Clarke – saw atomic power, wasn’t it?
Yeah, they did, and they’re not wrong. I still think that in the real world, our best bet for regular interplanetary travel is going to be ion propulsion, which requires a huge amount of energy, and so that’ll be reactors. This isn’t weird, way off in the middle of nowhere, made up science; this is real stuff. Humanity has put ion propulsion craft into space and used it, but if you scale that up big enough that you can have a passenger spacecraft, then you’re going to need to scale up the energy production. So, pretty much nuclear reactors are the only way to get that much energy out of such a small amount of weight.
The novel has a very non-traditional structure, essentially starting at two different time points, and unfolding from there in tandem. Was Project Hail Mary a difficult book to plot?
It wasn’t difficult to plot once I decided to use that structure, but it was a very difficult decision to go for that structure. I hate flashbacks. I always tell aspiring writers: “Don’t use flashbacks. Nobody likes them.” One of my main problems with flashbacks is, I’ll be really invested and interested in a story that’s going on, then suddenly we’re off somewhere else. We were over here doing neat stuff, now you’re over here doing boring stuff. This is a book, it’s entertainment, not a lesson. So, flashbacks often feel to me like you’re out playing with your friends and your mom tells you to come in and clean your room.
But I realized that this story, if told linearly, would be really weird. The whole scientific mystery which leads to the creation of the Hail Mary, and then the launch, is interesting, but it’s not a book… and so the flashbacks skip over the years. There’s this scene, and then the very next flashback you see will be two years later after that. The whole book would be really disjointed. From the second act on, it’s a completely different book. And so, I couldn’t think of any way to do this other than flashbacks. I’m like, “If I neat out the backstory bit by bit so that the stories kind of converge, and I’m constantly revealing new information in the flashbacks, then the flashbacks are compelling as well,” and just had the two stories come together at the end.
If this had been poorly executed, it would have been a very difficult read, but I felt no jarring at all due to the jumping backward and forward in time. I found myself looking forward to the next flashback, then getting back to the Rocky and Ryland show. I was also delighted to find there’s a lot of humor in there.
