Don't expect to see good science reflected here. I don't think that the producers engaged any real engineers to consult on technical aspects. For example: Astronauts reentering the space ship after an EVA are required to 'decompress' in the air lock for 20 minutes. Astronauts exiting the ship need to wait in the airlock, in their suits, for 60 minutes. Why this is done is not explained. Yikes.
