Hail Mary — Project

The story centers on , a middle-school science teacher who wakes up on a spacecraft with no memory of his name or how he got there. As his memories return through flashbacks, he discovers he is the sole survivor of a desperate, one-way mission to save Earth from "Astrophage"—a space-faring microorganism that is consuming the sun's energy and triggering a new ice age. Key Highlights

The story follows , a former molecular biologist working as a junior high school science teacher, who wakes up aboard a spaceship with no memory of who he is or how he got there . He quickly realizes he is the sole survivor of a three-person crew, light-years away from Earth . As his memory returns through flashbacks, Grace learns that humanity is facing an extinction-level crisis.

Eridians evolved under a thick atmosphere and see entirely through echolocation. He quickly realizes he is the sole survivor

Weir does something incredibly rare here: he creates an alien that is truly alien. The being, dubbed "Rocky" by Grace, has no concept of sight (his species navigates via echolocation and pressure detection). He lives in a high-pressure, high-temperature environment (100 degrees Celsius is comfortable for him), eats pure iron, and speaks in harmonic chords.
