I saw an early clip from this show. They have their equivalent von Braun figure who dreamed up the nuclear rocket colony ship. He appears in a grainy black and white documentary film that the colonists watch on the anniversary of their launch.
I could not quite figure out what the central conflict of the show is. They've been in space for 50 years, in many ways still culturally stuck in 1962. I think there is a murder, and so my guess is that one of the main themes is that their social order is about to fracture and maybe they are going to start coming apart.
