Beck is one tough cookie. In one moment, he decides to go against his orders and perform a risky maneuver, even though it could lead to a very nasty death. This is something we see time and time again over the course of The Martian.

It might sound new agey, but it's 100% true. Mark's story inspired countless individuals to join the cause and aid in his rescue, each making their own sacrifices—big and small—over those two years. Everybody contributed to getting him home, in their own way.

Finally, we get a brief glimpse of Mark's family. Although it's easy to get caught up in the suspense of Mark's exploits, we can't forget the real psychological strain they must take on his loved ones. Like Mark, however, we're separated from their perspective and unable to fully understand their feelings on this ordeal.
