'For all mankind' shows if the space race continued; brings to heart what these people felt after going up and to the moon only to be stuck in earth orbit maximum for the next 40 years.
In the second season they show new spacecraft designs that are based on actual proposals. Like the Sea Dragon super heavy-lift launch vehicle.
They also introduce androgynous mating system that is very similar to International Docking System Standard (IDSS) https://www.internationaldockingstandard.com/
What I particularly like about the show is how technology advances more quickly in their timeline - e.g. electric car, cell phones in the 1980s.
1G (analog cellular networks) already existed. NASA administrator might have had Motorola DynaTAC 8000X in 1983 even in our timeline.
EV car that runs 60 miles with a single charge is a real change to our timeline, but believable if the investment into EV would have been huge (needed in the moon and space in large quantities).
Overall, the worldbuilding that went into that show is impressive. Many events in the show actually happened, but are resolved differently or have different consequences.
It is a great show.
The radiation storm on the Moon was very nice, very mesmerizing, but story-wise, it was squandered. The heroism scene was mediocre.
Ronald Moore did great with Galactica, but this show is a mixed bag. Not that great.
Also, somehow they don't do good music in shows these days. It is too generic and forgettable.
