This review is based on all 10 episodes. Not bad at all. The pros: If you're a space fan, it's a must watch. It has good idea for a space vehicle. Although a lot of stuff isn't based on real science or NASA procedure, the story is about ordeals that Mars travelers face. Stuff may break down, people may break down, etc. The acting was very good and the "home front" stories were also good. Cons: Some stuff was just not believable, like whenever rank and protocol were thrown out the window. It was amateurish compared to what has gone on space, and astronauts did not always act like the best people their countries could offer. It felt like a high school drama sometimes. But overall, a very entertaining series. Bring on Season 2!!
