I am astounded that many have marked down this episode and this season because of the personal drama stories and political issues it touches. If you have watched from S1 you'd realised that this is a show that reimagines history (social, political and scientific) based on the premise that USA did not land on the moon first and that the space exploration program continued without it being mutilated by the politicians and bean-counters. Everything changes after this premise - the Space program contributes to massive changes in society and science! Also the personal stories of the participants are just as important! If those viewers who complain about the personal stories and the politics of the show want to watch a show focused only on space exploration then they'd better switch to one of the many space documentaries. The beauty of this show is that it shows the joy, pain, agony, conflicts, death and triumphs of the protagonists taking part in the space program. It is not a documentary.
