The Martian

Today we went to see a movie called The Martian. It is about an astronaut who is on Mars with his team and there is a huge storm. He gets knocked out by some debris and the crew thinks he's dead so they head home. Turns out he wasn't dead so now he is trapped on Mars with a limited food supply. He tries to grow potatoes and when he tries to make water with 2 hydrogen and one oxygen he uses solid hydrogen and liquid oxygen to make water. Unfortunately he forgot to account for the extra oxygen he had been exhaling so it kinda blew up in his face. He had a rover and inside of the rover there was a camera recording his progress. And I noticed that that camera was a Go Pro. I thought the movie was really amazing and it was based off of a book. And most of the calculations in the book were correct except for the first storm that the astronaut got knocked out in. The astronaut's name was Mark Watney and he was played by Matt Damon. I bet the book would be great too.
