Space & Exploration
Project Hail Mary
Ryland Grace wakes aboard a spacecraft with two dead crewmates, no accessible memories, and only fragmentary evidence of his mission. As he reconstructs his identity and purpose, he learns that Earth faces catastrophe from Astrophage, an extraterrestrial organism that is diminishing the Sun’s output. His destination, Tau Ceti, may hold the explanation—and a possible remedy. The novel combines an amnesia mystery, a sequence of scientific puzzles, and a first-contact story whose emotional center is an unexpected partnership. Andy Weir turns experiments, engineering improvisation, and competing planetary needs into suspense while asking whether courage is an inborn trait or a choice made under pressure.
