I vaguely recall something about the making of the movie where they acknowledge that this wouldn't happen, but it was done because that's what the audience expects.
Frustratingly, when the main character did exactly this in 2001: A Space Odyssey, the audience were frustrated because it was so unrealistic that someone would survive it (-_-)
I always thought that would be a good opportunity to teach people, but I guess if you're in it to make money it makes sense to just pander to what audiences expect.
It's not about pandering or making money (did people go to the movie because they heard there was a scene where a guy freezes in space?????), it is entertainment.
