Actually the expanse, for all mankind, and the martian are my erm ... I guess holy trinity of modern hard(ish) sci fi about space exploration. There is a lot of overlap in the fandoms of each and each series references each other to give a very unofficial shared universe feel. For example:
The expanse has had references to the USN Jamestown which is from For All Mankind (it was a model in the expanse in an office of a thing -trying to avoid spoilers - that appears in FAM)
The expanse had a ship named the MCRN Watney (Mark Watney is the name of the character in the Martian)
The Authors of each series have praised the other series and jokingly said that it's the same timeline/universe. I know it's not really but in my head cannon it is and I really LOVE that timeline.
I'd HIGHLY recommend all three as they are my favorite media properties.
The Foundation Series is really great (at least for the first 3/4). Its books obvious but the ideas are so good. The dialogue and characters are a bit basic, but it’s more than made up for by the story.
