For All Mankind explores what would have happened if the global space race had never ended. The series presents an aspirational world where NASA astronauts, engineers, and their families find themselves in the center of extraordinary events seen through the prism of an alternate history timeline — a world in which the USSR beats the U.S. to the moon.
Season 5 picks up in the years since the Goldilocks asteroid heist. Happy Valley has grown into a thriving colony with thousands of residents and a base for new missions that will take us even further into the solar system. But with the nations of Earth now demanding law and order on the Red Planet, friction continues to build between the people who live on Mars and their former home.
