And when she is approached about the chance to help save Earth, she is forced to question what she thinks she know OR IN WHICH a tour guide and a school teacher are humanity's last hope (I DO NOT OWN PROJECT HAIL MARY, I ONLY OWN CHARACTERS NOT PREVIOUSLY ESTABLISHED)

"I- Cathy, I never got over you even after fifteen years, what on earth makes you think I could get over you now?!" . . . From the very moment a young, shy and awkward Ryland Grace was approached by Catherine in the beginning of middle school, she had already captivated him in a way no one else before had. They were both young and naive, navigating through puberty together and questioning some of life's grandest mysteries at the ripe age of thirteen. Their friendship bloomed into a beautiful, tender connection built on trust and acceptance of one another. She would laugh at his silly jokes and listen to his rants, he would pay attention to every single detail about her. To him she was unique, special and very dear. Someone he deeply admired and harbored strong feelings for - feelings that he never dared name aloud. But their friendship would be brought to an abrupt end when Catherine is forced to move to another state due to her father's profession. Fifteen years would pass, a decade and a half without ever seeing, until fate would bring them together again, working in the same building with new challenges for the future.

One Solar System One Milky Way And one dying sun. Ryland Grace is a scientist/teacher who never wanted to be a hero, just someone solving problems in a quiet lab and to teach his children, far from the end of the world. But the world is ending anyway. Katlynn Briar always felt like she was destined to achieve something big for humanity. But when she finally gets the chance, it doesn't feel like triumph-it feels like weight. Like every answer she finds costs something she can't put back. But the universe doesn't care. When the Hail Mary project shifts from theory to reality, choices disappear. Governments decide. Orders are signed. And Ryland Grace is taken from Earth whether he is ready or not. They don't have a choice. Katlynn Briar is still there in the silence after the launch decision-watching the world continue as if nothing has changed, while everything inside her already has... And somewhere out in the dark, a ship turns toward the stars carrying one man who never wanted to leave...

Dr. Corinne Kennedy, a doctor and researcher, wakes up on a spaceship with amnesia, only to realize she is humanity's last hope to stop an alien microbe from eating the sun and freezing Earth. However, she is not alone. this fic is cross-posted on quotev (@.romantical) and ao3 (@.allthecheesesticks)

Humanity is dying, and Mira Bennett wakes aboard an unfamiliar spacecraft with no memory of how she got there. The only other living person on the ship is Ryland Grace - an anxious, endlessly rambling scientist who feels strangely familiar in ways neither of them can explain. As fragmented memories begin resurfacing, Mira uncovers the truth behind the Petrova crisis, the mission that carried them across the stars, and the unsettling realization that her connection with Ryland began long before either of them opened their eyes aboard the Hail Mary. Somewhere in the silence of deep space, survival may depend on more than science alone. Started: 5/19/2026

Ryland Grace doesn't remember his past. Lyra Novak doesn't remember Ryland Grace. Both of those things are a problem. Because somehow, humanity surviving becomes the easier part. Or: two touch-starved scientists with memory loss accidentally speedrun emotional intimacy aboard a spaceship without even noticing.

After the Solivagant takes an unintended trip across space-time and dumps Captain Y/n L/n in a universe that's not her own, she's left with a barely working ship, dead crewmates, and a fraction of her resources. Drifting through the vastness of deep space and with death nipping at her heels, Y/n is certain that the Solivagant will soon be her tomb. But life isn't done with her, yet. Rescued from the geospace of Erid's orbit, Y/n finds herself in the bio-dome of fellow human Dr Ryland Grace. Someone she knew, but also a stranger, a cosmic clone from a mirror Earth. As Y/n's body slowly heals, so does her heart. Can she find a new crew on Erid? TLDR: Rocky adopts another weird dog

Waking up in deep space with just herself and another man makes Clara Hayes instantly not trust him. There's no Earth. No backup. No clear explanation. Just a failing mission, a silent universe, and Dr. Grace-who seems just as lost as she is. Neither of them remember how they got there. No past they can fully access. No answers they can trust. Just instincts they don't understand and a shared mission that feels too important to ignore: save Earth. As they follow a mysterious signal across space, they're forced to rely on each other while trying to figure out who they are and why they were sent. But memories don't return clearly. They come back in flashes-feelings, fragments, names that almost surface before disappearing again. For Clara, one stands out more than the rest: a sister she can't quite remember, but can't stop feeling like she lost. The closer they get to the truth, the more everything starts to shift-not just the mission, but them. Because remembering doesn't just give answers. It changes everything.

After an incident on her spatial trip, Siena Gianessi finds herself on Erid, sixteen light-years away from Earth. Not only does she discover a whole new planet but she also meets Doctor Captain Ryland Grace, the savior of humanity. She always imagined him tall and mysterious, not awkward and talkative. Waiting for her spaceship to get fixed, she has no other choice than to live with the only other human on Erid. And maybe it's not that bad.
