So it all comes down to this. We review the season finale of “For All Mankind,” which puts the fate of the world in the crucible and makes us ponder the power of individual decisions when great systems seem intent on destroying one another. In addition to the dramatic life-and-death decisions, the plants at the bar are dead, Kelly has finished her essay, and we’re given a tantalizing look at what the 1990s might bring. Onward to season three! Host Jason Snell and Dan Moren.

Things are getting pretty serious. The clash of civilizations between the U.S. and the Soviets begins to boil on Earth, in space, and on the surface of the moon. Karen continues making interesting personal decisions. Dani reveals herself to be an old-school “Star Trek” fan. Ellen’s future complicates her present. And how about that cliffhanger?! Like we said, things are getting pretty serious. Host Jason Snell and Dan Moren.

Things keep getting more tense! This week Karen owns her ability to make terrible decisions, Gordo vanquishes an old nemesis, Sally Ride is not amused, there’s a meet-cute in a mock-up, and Kelly tries banh mi for the first time. Oh, and there’s a fateful incident on the moon. Host Dan Moren and Jason Snell.
