Andy Weir

A lone astronaut is on a desperate, last-chance mission to save the earth from disaster in this incredible new science-based thriller from the #1 New York Times bestselling author of The Martian. 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. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but a computer and two corpses for company. His crewmates dead, his memories fuzzily returning, he realizes that an impossible task now confronts him. Alone on this tiny ship that's been cobbled together by every government and space agency on the planet and hurled into the depths of space, it's up to him to conquer an extinction-level threat to our species. And thanks to an unexpected ally, he just might have a chance. Part scientific mystery, part dazzling interstellar journey, The Hail Mary is a tale of discovery, speculation, and survival to rival The Martian--while taking us to places it never dreamed of going.

Gravity doesn’t just “go away” when you’re in orbit. In fact, the gravity you experience in orbit is pretty much the same as you’d experience on the ground. The weightlessness that astronauts experience while in orbit comes from constantly falling. But the curvature of the Earth makes the ground go away at the same rate you fall. So you just fall forever

It’s a weird feeling, scientific breakthroughs. There’s no Eureka moment. Just a slow, steady progression toward a goal. But man, when you get to that goal it feels good.

And just like that another climate denier is born. See how easy it is? All I have to do is tell you something you don’t want to hear.

For fifty thousand years, right up to the industrial revolution, human civilization was about one thing and one thing only: food. Every culture that existed put most of their time, energy, manpower, and resources into food. Hunting it, gathering it, farming it, ranching it, storing it, distributing it…it was all about food

It’s rare to find a scientist who is also a good administrator

Antarctica used to be a jungle. For millions of years it was as lush as Africa. But continental drift and natural climate change froze it over. All those plants died and decomposed. The gases from that decomposition—most notably methane—got trapped in the ice.”

Also bin ich ein Mann Mitte dreißig, der allein in einem kleinen Apartment lebt, ich habe keine Kinder, aber ich mag Kinder sehr. Mir gefällt nicht, wohin das führt... Lehrer! Jetzt erinnere ich mich! Gott sei Dank. Ich bin Lehrer.

»Tja, jetzt bist du nicht mehr allein, Freund«, sage ich. »Wir sind beide nicht mehr allein.«

“I penetrated the outer cell membrane with a nanosyringe.”

“No!” I said. “Well. Yes. But it was a scientific poke with a very scientific stick.”

A lone astronaut must save the earth from disaster in this incredible new science-based thriller from the #1 New York Times bestselling author of The Martian. 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.

A Novel

Good. The science was the cool the plot was cool.

Loved this book - it was interesting, funny and at times very touching. Or simply - Amaze amaze amaze :)

A Big Mac is a burger with no real substance. It was purely made to taste good and appeal to the masses.

Project Hail Mary is literary equivalent. A book that leaves no lasting impression and boils down to pure competence porn. The plot’s loop is as followed: problem occurs, and three pages later, it is immediately resolved. Whenever Weir writes himself into a narrative corner, the rock thing just pulls a solution out of his ass, which is lazily payed off as the “galaxy’s greatest engineer” or something about the magical mechanics of Xenoite.

Andy Weir is great at coming up with plots, but someone needs to tell him to ease up on the "problems" that arise along the way.

I know: problems are what make a story interesting. If Frodo just tossed the ring in an unguarded volcano, which was in his backyard, it wouldn't make for a great trilogy. With Weir, however, I think someone needs to tell him that each plot point should probably only have one problem and solution.

Like I did with "Annihilation", I will try not to compare this to the film; but there's no denying that the filmmakers' choices of streamlining the plot were wisely chosen cuts. Do we really 

 the section where Grace borrows fuel from the beetles? It's not very interesting, it just showcases how smart he is, but that's also like 80% the way through the book; I think we know he's a smart guy several hundred times over by then.

And that's not the only instance, it happens plenty of times before and even again AFTER this, just before the very end. It's extremely clunky and starts to feel like science-thesaurus ramblings, or worse, Weir just masturbating his space-obsession factoids and brilliance in front of everyone barely-disguised as plot.

This book has horrible pacing issues. Someone needs to tell Weir about story beats and how to chill out a bit on throwing in yet another problem that needs a solution explained tediously.

BUT, this book shines in its partnerships and cooperation. In an attempt to avoid spoilers, I'll say there are many cute moments in the book and brief bits of action are written pretty well. And again, the overall plot and its mechanisms are good ones.

I won't be reading his third book. "The Martian" was a better movie than book and so was this. A pattern is emerging: when the "Artemis" movie comes out, I'll just pretend it's original.

I do not recommend "Project Hail Mary", the book. I do recommend the movie.

If I was rating this book critically, I’d probably give it less than five stars. But luckily, I don’t read to critique. 

I wish I could describe this book in a way that could communicate how I felt when I was reading it. Quite literally, my life felt brighter for a week because I knew as soon as I got home I could keep reading Project Hail Mary. It was so fun in a way that a lot of the more existential nihilistic stuff I usually read isn’t, it was genuinely refreshing. Grace and Rocky’s relationship was so pure in a why that most franchises that delve into the realm of aliens aren’t. Rocky isn’t hostile, Astrophage (despite being the main “antagonist”) isn’t hostile and they’re never assumed to be - Hail Mary nails the sense of wonder in the pursuit to find and communicate with extraterrestrial life without all the fear and violence most alien heavy media tend to drift towards.

Grace is a dorky, nerdy and overwhelming hopeful character who was an absolute joy to read. His contrast with Stratt was excellently executed, and when they dropped 

 bombshell (in the last 100 pages of the book no less), I genuinely cried along with Grace. That made his actions for the previous 400 pages feel so much more meaningful than they already did and made each choice he made after all the more impactful. And not to mention him going back for Rocky. Oh my god. I cried for at least 10 minutes.

Rocky was a pleasure too. His manners of speech were so funny, and I love the way Weir made sure to capture his body language in such a believable way. His willingness to sacrifice himself from Grace because of what happened to his crew resulted in another 10 minute crying episode. 

Even the side character, though very minimal, felt just fleshed out as their protagonist counterparts. I loved Dimitri and Leclerc.

All in all, an amazing book. Andy Weir, you’ve outdone yourself again.

Project Hail Mary by Andy Weir is a high-stakes space sci-fi adventure that's heartwarming as well as heartbreaking. The book has been on my list for years, but I was a bit hesitant to read it... unsure if it could live up to the hype. And I’m glad, it did.

It’s about Ryland Grace, a middle-school science teacher turned astronaut (who wakes up alone on a spaceship with no memory of his mission), and “Rocky,” an engineer from the planet Erid. As Grace’s memories return, he realises he’s Earth’s last hope for destroying a star-eating microbe called Astrophage.

This is one of those rare sci-fi stories that feels both wildly imaginative and oddly believable. Yes, the story seems quite real... something that can actually happen someday. Unlike many sci-fi, the science in Project Hail Mary felt real, not just futuristic tech.

It’s conversational, sarcastic and filled with some nerdy enthusiasm that I could see myself in. The book was funny and engaging throughout. Plus, it made scientific concepts feel approachable, giving you an idea of how physics, space science and astronomy work in general. It was all charming for me... knowing how things work just for the sake of knowing them.

The story alternates between Grace’s present-day survival in the Tau Ceti planetary system and flashbacks to his days on Earth. Even with these constant timeline shifts, it never felt confusing. The transitions were smooth.

Rocky, the alien engineer, was a lovable character. The communication at the beginning felt quite adorable, almost like talking to a baby and figuring out what they want to say. Project Hail Mary might become my favourite science fiction (ever) just because of the Grace-Rocky friendship.

If there’s one slight downside to the book, it’s that the space part felt like it ended a little too soon. I wanted more moments of Grace and Rocky running science experiments and building new things.

But no complaints. The book left me smiling at the ending. Fully satisfied, content to heart. And I’m writing this all still teary-eyed.

Project Hail Mary is definitely a recommendation. But beware, it’s gonna ruin other space sci-fi books for you. It’s part survival thriller, part science deep-dive, and part story about friendship. The info-dumps may feel a bit too much, but they don't drag the story a lot.

I’m having a hard time writing a review that would do this book justice.

The whole thing just felt so human. Even with all the science and space stuff, it really comes down to connection, trust, and doing what you can for those you love.

The characters are so lovable and relatable. My face was leaking but the ending was everything I needed and more. 

So worthy of the hype. I can’t wait to finally go see the movie now!

my secondary school science knowledge was used more making sense of this book than it’s ever been in yEars

probably first sci fi book i’ve properly read and ,,, i did prefer the movie :: more dumbed down but just my speed with the right amount of heart.

i do just love bros being bros : the earnestness & pure intentions of rocky to just,, care for grace ?? because it’s obvious that he would!! not because it’s an obligation ?? gets me every time yeah maybe they are ”good people”

Read it before the movie came out. I loved it. even the science stuff. the movie skips a lot of science and reasoning and few important events, the book is always much better. this was my first scifi book and i will definitely pick more like these now.

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.

All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.

And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.

Or does he?

rocky, grace, and their friendship is everything to me

Love the creativity and the thoroughness of the book. I was sucked in for at least 4/5ths but the last bit felt hard to get through. There’s a twist - there’s always a twist - and I felt the author leaned in to science too deeply during that twist, losing my attention a bit. I wanted drama in the last part, not to follow a science lesson.

Sarah Wilson

A great adventure and a new take on sci-fi that really engaged me more than other sci-fi books have in the past. The characters were compelling as well as the story. Definitely worth a read.

The friendship carries this whole story. Outside of that, it’s not really anything we haven’t seen before. Still adorable.

Me senti assistindo um filme enquanto lia e que privilégio é saber que vou ver o filme ainda essa semana??!? Legal demais, passa longe de qualquer coisa que eu já li, em questão de gênero e de tudo, sinceramente. A quantidade de eventos fazem o livro ser uma grande montanha russa de acontecimentos e emoções, mas eu não poderia imaginar um final melhor. No fim das contas, ele nasceu para ser professor, um grande homem que ensinou e aprendeu com o Rocky, um ser completamente novo em todos os sentidos. Estou impactada como futura professora!

getting deeply attached to a metal space spider who asks to be fisted was not on the agenda for the big 2026. neither was crying bc of a sci-fi book, but here we are. absolutely spectacular.

This might have been the best audiobook I’ve listened to this year. ROCKY IS MY GOAT. ROCKY IS FRIEND!!!

did not expect to cry over a sci fi book but here we are!
