This show was so unrealistic it wasn't watchable. They created drama simply for the sake of creating drama. And not even realistic drama for a sci fi show. It was just cheap. I'm so disappointed because there is real drama that would take place on a mission to Mars. The writers should have done their research on real astronauts.
When they encountered a real potential problem, the show introduces more personal problems to confound the real problem. Like the solar panels wouldn't deploy, that's legit. But as that's going on, its revealed that the daughter of one astronaut is estranged and the husband of the other may be paralyzed from a stroke he had hours before the mission launches. I also doubt that a team of astronauts that get along so poorly would be sent on a three year mission.
