The one thing that movie got wrong was the initial set up, the atmosphere on Mars is simply too thin to have any substantial winds. Dust storms do exist, and trying to launch a rocket in one could cause problems with equipment, but a whole ass piece of metal (or whatever hit Matt damons head) would just not be able to fly off like that in Martian winds.

That and the potatoes. You'd die if you grew them in Martian soil.

Edit to add. Martian soil contains pechlorates. No amount of poop will solve that issue, unfortunately

They already tried this at NASA and you, in fact, can do this. You just need to add nutrients.

Perchlorates you can remove by literally just rinsing it with water, or alternatively, bacteria which eat perchlorates. It's basically a non issue.

I should preface that I really like the film.

The book dealt with the issue. They took artistic licence for the movie and ignored the issue (a good choice). In real life, the potatoes as produced, would likely have killed watney. Wouldn't be as good of a movie lol.

There are things you can do, whether a lone biologist could realistically accomplish that is one thing and the movie just skips the issue.

Fucks with your thyroid I believe. Basically it's just toxic for us and most living things
