“Project Hail Mary” by Andy Weir – Review

By: Angie Haddock

Ryland Grace is the sole survivor on a desperate, last-chance mission–and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.


This is the third official full-length novel from Andy Weir, who is mostly known for having written “The Martian.” (Even if you didn’t read that one, you may have seen the Matt Damon movie version.)

If you’re familiar with Weir’s other works, you will find this to fit right in. It’s heavy on science (and math), and comes in just under 500 pages. It also focuses on a character who needs grit and ingenuity to survive his circumstances, and it’s full of humorous asides.

The actual plot is entirely different than that of “The Martian” or “Artemis,” obviously, but how much can I tell you without being spoiler-y?

The story goes back and forth between what Grace is doing on his spaceship, the Hail Mary, and what happened on Earth before the ship’s launch. In these flashbacks, both Grace and the audience learn what his mission is, and why he’s involved.

That second part turns out to be a bigger deal than you’d think. More on that later.

We learn that our sun is being attacked by a small organism that humans name “Astrophage.” It’s reducing the sun’s energy/light output, which puts Earth on track for catastrophe in approximately 26 years. (Even a slight reduction in the Earth’s temperature will cause crop failures in some areas, leading to collapses of food chains and extinction of various species. It’s like current discussions of climate change, except with everything getting colder.)

Grace is a junior high biology teacher. So how does he end up on a space mission? We learn first how he got involved in researching astrophage, which makes slightly more sense. As the preparations ramp up for figuring out how to deal with the astrophage problem, Grace stays with the team determining what to do next. At this point, he knows more about astrophage than anyone else, so this still makes sense. We don’t learn how he actually ends up on the ship until we’re 80% through the book, and… it’s a total gut punch.

While this mystery keeps you guessing in the flashbacks, the real joy of the book happens in the segments on the ship. Grace has traveled to another solar system that seems to also have astrophage present, to see what’s happening there and if it can help Earth in any way. He’s been asleep for most of the trip, but now has to find what he’s looking for – once he remembers what that is. This is not as lonely and boring as one might think, but I don’t want to give away what happens. Let’s just say it’s fun, sometimes heartbreaking, and ultimately pretty awesome.

I am a classic right-brained person who is not great at science-y things, therefore I took this one kind of slowly. I didn’t look up the things he was talking about, to try to understand the science behind it. I know Weir is known for doing a good job with this stuff, overall, despite fictionalizing where needed. I just kicked back and enjoyed the ride. And it’s totally one you can enjoy, if you like science fiction at all.

This is sure to be another blockbuster under Weir’s belt, and it comes out today, May the Fourth. I was able to read an advanced copy through the publisher, Random House, and Netgalley.
