Strange action in the movie
I just saw the movie for the first time a few days ago, and there was something that made no sense to me. I was wondering if anyone might be able to explain it.
Near the end of the movie, when the crew realizes they need to slow down the ship to intercept Mark, the commander has the one astronaut travel, outside the ship, down the length of the ship to the forward airlock. There he goes inside where the computer technician hands him the bomb, which he then sticks to the door then goes back out and travels back down the length of the ship to his post.
Why didn't the computer technician stick the bomb to the door herself? There was absolutely no need that I can see for the other astronaut to make that dangerous journey outside twice.
