THIS Sunday Blog is about the book/movie Project Hail Mary. If you did not yet see the movie or read the book (or listen to the book) you might want to find an exit now.
In Andy Weir's novel Project Hail Mary (and its film adaptation), Ryland Grace is not a trained astronaut at the start. He's a former molecular biologist who became a middle-school science teacher. He gets pulled into the project because of his unique expertise on astrophage (the alien microbe threatening Earth's sun), based on his earlier controversial academic work about life not necessarily needing water.
Eva Stratt, the no-nonsense director of the international effort, recruits him early on. Over time, as the mission develops, Grace becomes deeply involved in planning and preparation for the Hail Mary spacecraft. He helps design experiments, trains the actual selected crew (the primary science specialist and backup) on the astrophage science they'll need, and participates hands-on in many aspects of the project.
Key reasons he knows the "astronaut training" procedures
Stratt plans for every contingency, including the possibility that something could go wrong with the primary crew. Grace effectively serves as a tertiary (third) backup science specialist all along, even though he has no intention of going on the one-way mission himself.
Because of this, he undergoes a lot of the same rigorous preparation and testing that the astronauts do:
- He participates in simulations.
- He tests equipment (including EVA/spacewalk suits and tools—he even acts as a guinea pig for some of those tests).
- He gets familiar with ship systems, procedures, zero-g operations, and other mission-critical skills under the guise of supporting the team or verifying the science setup.
In the story's present-day timeline (aboard the ship), Grace wakes from a long coma with amnesia. As his memories return through flashbacks, he pieces together his involvement and applies that accumulated knowledge to operate the spacecraft, perform EVAs, troubleshoot systems, and improvise solutions. His scientific mindset and prior hands-on exposure fill in the gaps. He's not magically an expert pilot, but the preparation he received (plus the ship's automation and his own ingenuity) lets him manage.
The book emphasizes this more explicitly than the movie in some spots: Stratt had been subtly ensuring he was 'as prepared as possible' because she always viewed him as a potential fallback. It's a classic Weir-style "competence through preparation and problem-solving" detail that makes Grace's solo survival plausible without turning him into a superhuman astronaut overnight.
So my wife and I enjoyed the movie. And I downloaded the book on Audible. (I highly recommend you do both). But on the drive home last night we talked about how Ryland Grace knew all of the Astronaut stuff - he was never trained! We could not stop thinking about this 'flaw' in the movie. So, this morning I did the Ryland Grace thing myself: I asked Grok and Gemini and a few of my other AI friends to help me to solve the riddle.
HERE IS THE POINT...
In the book, they do indeed go into much deeper detail as to how and why Ryland Grace was able to perform all of his Astronaut duties. In the movie, right up to the point he is forced aboard under an induced coma he keeps saying "I'm not an Astronaut! I was never trained! I don't know anything about anything!" A book on Audible with 16 hours of conversation would always have more detail than a 2 1/2 hour long movie, right? Ah so. Mystery solved.
Happy Ending: Ryland Grace figured it out. As they say over and over again: You are smart. You will figure it out.
Is there any better example of 'Distance Learning' than Project Hail Mary? Hmmm, maybe.
Once again, welcome home to the crew of Artemis II.
