Apple TV+ has given a green light to more For All Mankind.

The speculative space drama series will return for a fifth season, according to the streamer today.

Additionally, a spin-off series, Star City, from For All Mankind creators Ronald D. Moore, Matt Wolpert and Ben Nedivi is planned.

“Our fascination with the Soviet space program has grown with every season of For All Mankind,” said executive producers Wolpert and Nedivi. “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. We could not be more excited to continue building out the alternate history universe of For All Mankind with our partners at Apple and Sony.”

“With each new season, For All Mankind continues to build out a fascinating world and capture global audiences through high quality storytelling that has been so skillfully developed by Ron, Matt and Ben,” said Matt Cherniss, head of programming for Apple TV+. “There is so much to explore, and we, along with our partners at Sony, can’t wait to dive into this next chapter of the engrossing ‘For All Mankind’ universe.”

Star City is described as a propulsive, paranoid thriller that takes us back to the key moment in the alt-history retelling of the space race — when the Soviet Union became the first nation to put a man on the moon. But this time, we explore the story from behind the Iron Curtain, showing the lives of the cosmonauts, the engineers and the intelligence officers embedded among them in the Soviet space program, and the risks they all took to propel humanity forward.

All four seasons of For All Mankind are now streaming globally on Apple TV+.
