This is one of the best series I have seen in recent times. I could barely stop watching it and finished it within 2 days. The story is told in a really compelling way, touching on the human side of the astronauts. All the actors gave top notch performances and the story has a bit of everything: those tense moments, really touching bits and it is laced with humour as well. This is a really lovely series and I cannot recommend it highly enough. I loved it so much!
