Get ready for a good old fashioned movie debate, because the women of NASA have weighed in on the best and worst space movies, and it is causing a lot of discussion online. BBC interviewed a number of women at NASA to ask them what they thought of space-themed movies, as well as some TV shows, and true to their scientific roots, they tended to opt for more scientifically accurate movies.

The Martian, Hidden Figures, and Apollo 13 got the highest praise from NASA women, which is not surprising since two out of three of them are based on true stories. And a lot of scientists tend to be sci-fi nerds, so it’s not surprising they also chose movies like Star Wars and Star Trek which aren’t really based in science but make no claims to be.

As far as the worst movies, they tend to go after near-future stories that pretend to rely on science but really don’t, like the Bruce Willis movie Armageddon. They also really didn’t like Gravity, the Sandra Bullock and George Clooney thriller, noting that Bullock’s character was able to easily move between orbits and did not wear a diaper as astronauts would. Also, NASA as a whole wasn’t pleased with the movie because it shows everything going wrong and might cause people to lose confidence in the work of NASA scientists.
