What is For All Mankind season 3 about?

Set in the 1980s and early 1990s, For All Mankind season 3 features a new goal: Mars. This time, though, the only way for the US to achieve the goal of making it to the red planet is by joining Helios and the Soviets in a three-way race. The only thing that matters is getting there first, even if it means banding together to do it. 

Mars is the next big stepping stone in the Space Race. A Mars outpost is essential to the future of space travel and the colonization of other planets, NASA is set on making sure that they get the job done no matter the cost–or the danger.

Here is the official For All Mankind season 3 synopsis:

"The red planet becomes the new frontier in the Space Race not only for the US and the Soviet Union, but also an unexpected new entrant with a lot to prove and even more at stake. Our characters find themselves going head-to-head as their ambitions for Mars come into conflict and their loyalties are tested, creating a pressure cooker that builds to a climactic conclusion."
