Project Hail Mary hits the big screen, this week on Planetary Radio.

I'm Sarah Al-Ahmed of the Planetary Society, with more of the human adventure across our solar system and beyond.

What would you do if you woke up alone in space

with no memory of who you are or how you got there?

But somehow, the fate of every living thing on Earth

depends on you figuring it out?

That's the premise at the heart of Project Hell Mary,

author Andy Weir's latest science fiction epic.

Now a major motion picture starring Ryan Gosling.

Matt Kaplan, our senior communications advisor and I,

will share our very first reactions to the film straight out of the theater.

Then we'll travel back in time to hear Andy Weir,

the author of The Martian, Artemis, and Project Hail Mary,

and the producer of this film,

as he tells us in his

own words what the story is really about in an earlier conversation with Matt. After that,

award-winning nature correspondent Alex Wittsey takes a critical eye to the science in the film.

Astrophysicist and Professor Nahum Arrav from Virginia Tech's Department of Physics walks us through

something life on earth will have to face someday, the actual death of our star. And finally, we'll close

with What's Up with Bruce Betts, our chief scientist. A quick note before we dive all the way in.
