Folks hoping to see more of Apple TV Plus’ For All Mankind series are in for a treat, but the streamer is working on more than just a new season.

Today, Apple announced that For All Mankind has been renewed for a fifth season that will continue to chronicle the alternate history of a world in which the Soviet Union is the first nation to put a man on the Moon and the United States set out to catch up with its rival. Following the show’s season 4 finale, news of the renewal doesn’t exactly come as a surprise, but Apple also revealed that executive producers Matt Wolpert and Ben Nedivi are working on a new series titled Star City, which will dig deeper into the live of the Soviets who changed the arc of human history.

In a statement about the new show, Wolpert and Nedivi described how — as For All Mankind’s story jumped 10 years into the future with each season — their fascination with the concept of the Soviet space program continued to grow. And with the original series set to jump another decade in its fifth season, it felt like a prime time to also look back at the space race from the Soviets’ perspective.

“The more we learned about this secret city in the forests outside Moscow where the Soviet cosmonauts and engineers worked and lived, the more we wanted to tell this story of the other side of the space race,” the pair explained. 

Described by Apple as a “propulsive, paranoid thriller,” Star City will focus on the cosmonauts and engineers who poured their lives into the Soviet Space program in order to realize a dream that didn’t always seem possible. Aside from Wolpert and Nedivi, who will showrun the new series, no other details about Star City’s creative team, cast, or premiere date have been announced as of yet. There’s also no word on when For All Mankind’s fifth season will debut, but now feels like a pretty solid time to get into the show if you’ve been holding out.
