What is project hail.mary rocky?

Project Hail Mary is a science fiction novel written by Andy Weir. The book was published on May 4, 2021, and is Weir's third novel after "The Martian" and "Artemis". The story follows Ryland Grace, a lone astronaut who wakes up with amnesia aboard a spacecraft bound for the Tau Ceti star system. As he pieces together his memories, he realizes that he has been sent on a mission to save Earth from an extinction-level event caused by a microbe that feeds on sunlight and is spreading rapidly throughout the solar system.

The title of the book is a reference to a hypothetical last-minute attempt to save a desperate situation, as if throwing a "Hail Mary" pass in football. The story deals with themes of isolation, memory, and the resilience of the human spirit in the face of overwhelming odds.

The novel has received positive reviews from critics and readers, with praise given to its scientific accuracy, humor, and compelling characters. It is currently being adapted into a film by MGM, with Ryan Gosling attached to star as Ryland Grace and Phil Lord and Chris Miller set to direct.
