Jeff Williams
Jeff Williams asked Andy Weir:

Did you feel at any point (or points) in the novel that you might need to use inaccurate science as a plot driver to give the story more 'oomph,' or was that never a problem?

Andy Weir Yes. I tried to keep it to a minimum but I did cheat in a few places.

See this question for why the sandstorm would not cause any problems: https://www.goodreads.com/questions/2...

Also the radiation shielding they had is completely fictional technology.
