Hollywood science often gets a bad rap because, well, it’s Hollywood and they insist on “looks cool” versus “is cool because it just fucking is”. But! Sometimes they actually do their research, talk to some people who know some stuff or adapt a book by a guy who knows what he’s talking about. For those who’ve already seen it and loved it, NASA has an interesting post about real technologies featured in The Martian (which I am dying to see).
