1952 Colliers' article: "Man Will Conquer Space Soon!"
Some of the best scenes in HBO's From Earth to the Moon were about how the engineers tackled designing the LM and expositing all sorts of things about the technical challenges. I still enjoy the show, but I really wish they catered to the space-nerd audience a little more by spending a little less time on interpersonal drama.
The biggest for instance: in our timeline gay rights advances were able to piggy back on other civil rights advances and waves of feminism. In getting major civil rights and feminist victories early in space it seems like not as much happens "on the ground" as it did in our world, especially with regard to follow up rights such as gay rights.
The next biggest and certainly much more obvious is that the Cold War is much, much worse and international politics a bit more fraught and MAD overall.
There's lots of little other things like earlier backslides in immigration policies. There's deep implications that tobacco companies won for longer and there's less EPA power and there's a lot less public awareness of radiation concerns and carcinogens. (Things that stopped, for instance, real world Project Orion from anything like tests in Earth's atmosphere.)
So much of these details are easy to miss in the background, and again I don't know how much is intentional commentary versus accidental bits of world building. A lot of people joke about all the Beatles Reunion Tour of the 90s stuff as evidence that the world building of FAM has overly generously been "super optimist utopia" the show claims to have created, but if you actually pause some of the headlines and stories there's a lot of nasty stuff, too, including a lot of interesting digs into that same Reunion Tour with shades of "aged rockers past their prime who don't like each other anymore don't bring anything new or exciting to label requirement to tour again".
I can't fault the show for being optimistic and it's a big reason I tune into the show because I want that "competence porn" of smart people doing cool smart things. I don't think the intent is "utopian" though, I think the writers understand if all the smart people are busy doing smart stuff in space, there's fewer smart people on the ground and some of that bleeds into the world building and I appreciate that as a viewer.
