I suspect that much of the technical stuff in Project Hail Mary is probably also right on the money. He gets off on relativistic physics, orbital mechanics, and the history of manned space flight.

HAIL MARY ANDY WEIR SOFTWARE
After all, for much of his life, Weir was a software engineer and an amateur rocket scientist. But I’m pretty sure most of what he wrote was factual. I let him fudge a few things (such as Martian sandstorms) for the sake of the story. Now, I took a lot of Weir’s science in The Martian on faith. Needless to say, Grace needs much more science than Watney did. In Project Hail Mary, the timeframe is expanded and contracted by relativity, and the distances are measured in billions of miles and light-years. The distances are measured in millions of miles. In The Martian, the timeframe Watney deals with is months and years. Through a series of flashbacks, memory jolts, and brilliant reasoning, he figures out that there is more at stake than potatoes or his own life.

In Project Hail Mary, Ryland Grace awakens on a spaceship without knowing how he got there or if he is even an astronaut. For one thing, he has to grow potatoes in a place where nothing grows. In The Martian, the protagonist, astronaut Mark Watney, is accidentally stranded on the Red Planet and must use all his scientific knowledge to survive until Earth can mount a rescue mission and save him. As he proved in his breakout novel, The Martian, Weir can spin a yarn and make a reader think. (That’s not a misprint you’ll have to read the book - which I hope you do - to get the pun.) In fact, its author, Andy Weir, has many detractors who point out that his writing style leaves much to be desired, his humor is borderline juvenile, and he can be politically preachy.Īll of this is somewhat true, but it’s beside the point. Project Hail Mary is not everyone’s cup of Tau.
