Check engineering at the door, but a lot of it is visually comparable. I view it in the same vein as The Right Stuff. Not accurate, but captured the feelings of the times. Things like the orbit altitude and inclination of Hubble vs. ISS are off. Spacesuit wise, lots wrong, but I can only see that because I worked on the real ones. Every astronaut I know that has gone to see it has said similar things. With all of that said, it's my favorite movie this year.
