That’s a tough one. I’d recommend the book first, but I can see arguments for both orders.

By reading the book first, you’ll have a better background and understanding of the context of the plot, the science, and the overall objectives of the mission. There are also several “twists” in the book that were cut from the movie for runtime.

I enjoyed the movie after reading because I got to see the story “come to life”.

But I could also understand the perspective of enjoying the movie first, and then having the story/world expanded 8x with a 16hr book.

You’d could equate “movie -> book” order to watching the LoTR standard editions first, and then watching the extended editions.

I listened to the audiobook narrated by Ray Porter (on Audible) and would recommend that production if you enjoy audio.

I don’t think you can go wrong either way :)
