Suggested correction: I don't think that is correct. When he first comes up with the idea to reroute the Hermes back to Mars he was thinking about/ working on the calculations for the original probe before it blew up.

Mistakes

Other mistake: During the storm scene in the beginning of the movie, the astronauts' faces inside the helmets are brightly lit, meaning there's a light source pointed directly in their face. That's something that would render them mostly blind and unable to see and appears to be nothing but a dramatic effect for the camera. (00:05:00 - 00:08:00)
