Apple TV is officially taking For All Mankind behind the Iron Curtain. The streamer has dropped the first trailer for Star City, a new spin-off set in the same alt-history universe, but told entirely from the Soviet side of the space race. If For All Mankind asked what might have happened if the Soviets beat the US to the moon, Star City leans into that question by moving the camera into the forests outside Moscow, inside the closed city where cosmonauts, engineers, and KGB handlers live, work, and quietly watch each other.

The show lands on Apple TV on Friday, May 29, with a two-episode premiere followed by weekly drops through July 10, so it is being treated as a proper summer event series rather than a small side project. It runs eight episodes, and Apple is very clearly positioning it as a “bold” expansion of the For All Mankind universe instead of a one-off curiosity bolted onto a successful sci-fi brand. For fans, that means this is not a prequel movie or a character special; it is a fully fledged drama that is expected to stand on its own while still rewarding anyone who has spent four seasons watching NASA scramble to catch up.

The trailer itself wastes no time making its pitch. Instead of familiar Mission Control desks, we get dim corridors, surveillance rooms, and cramped Soviet control centers humming with analog tech. The editing style leans hard into thriller territory: tight close-ups, whispered conversations, coded language, and the constant sense that someone is always listening just out of frame. If For All Mankind is a space race drama with political edges, Star City immediately comes across as a paranoid spy thriller that happens to be obsessed with rockets.

Apple is calling it “a propulsive, paranoid thriller” that rewinds the timeline back to that first pivotal divergence: the Soviet Union, not the United States, puts the first man on the moon. But this time, we are not watching the landing on grainy TV inside American living rooms; we are embedded with the people who made it happen and the state security machine built to control them. The series promises to track cosmonauts, engineers, and intelligence officers all living in the same sealed ecosystem, each with their own conflicting loyalties to country, family, science, and basic survival.

Fronting that tension is an impressive cast. Rhys Ifans, fresh off House of the Dragon, plays the Chief Designer, described as the driving force behind the Soviet space program – think brilliant, volatile, and indispensable in all the worst ways. Opposite him is BAFTA winner Anna Maxwell Martin as Lyudmilla Raskova, the steely head of the KGB surveillance division at Star City, whose job is to keep the dream of Soviet space dominance alive by making sure no one steps out of line. Agnes O’Casey plays Irina Morozova, a newer recruit in that surveillance apparatus, inheriting a role previously glimpsed in For All Mankind and now getting real narrative weight. Rounding out the ensemble are Alice Englert, Solly McLeod, Adam Nagaitis, Ruby Ashbourne Serkis, Josef Davies, and Priya Kansara, giving the show a mix of familiar prestige TV faces and rising genre names.

Behind the camera, this is not a spin-off farmed out to a random new team. Star City is once again coming from Ronald D. Moore alongside Ben Nedivi and Matt Wolpert, the trio that built For All Mankind into one of Apple’s most acclaimed original dramas. Nedivi and Wolpert are back as showrunners and executive producers, with Moore and Maril Davis producing via Tall Ship Productions, and Sony Pictures Television staying on as the studio partner, just like the flagship series. That continuity matters: it suggests the alt history rules, the long-term story arcs, and the sense of grounded engineering detail that define For All Mankind will carry over rather than being softened for an easier thriller.

If you have not kept up with For All Mankind, the quick primer is that its universe branches from a single “what if”: the USSR beats the US to the first crewed lunar landing, and instead of the space race cooling after Apollo, it accelerates. Over four seasons, the show has pushed that divergence forward through the 1970s, 80s, 90s, and beyond, using real hardware, real historical figures, and very fictional missions to Mars and the asteroid belt to explore politics, gender, economics, and corporate power. Star City plugs into that same lineage but goes back toward the beginning, turning the Soviet program – something mostly glimpsed from afar – into the main stage.

Nedivi and Wolpert have said their fascination with the real “Star City” – the closed cosmonaut training complex outside Moscow – kept growing as they researched storylines for the main series, especially once they learned just how secretive and self-contained that community was. It is a dream setting for drama: a town that technically does not exist, full of national heroes who cannot talk about their work, watched by people whose entire job is to ensure nothing leaks beyond the barbed wire. That makes Star City an ideal vehicle to explore a recurring question in this universe: how much risk are you willing to take for the chance to push humanity further into space, and what does it cost you when the state owns both your ambition and your fear?

From a pure streaming strategy perspective, Star City is a very Apple move. Since launching Apple TV back in 2019, the company has treated a handful of shows as core pillars – Ted Lasso, Severance, Silo, and For All Mankind chief among them – then built out worlds around those brands instead of chasing massive libraries. The numbers back up that approach: Apple Original series and films have racked up hundreds of awards and thousands of nominations in just a few years, with For All Mankind consistently showing up on “most underrated” and “best sci-fi of the decade” lists. A good spin-off gives Apple a way to deepen that universe without asking newcomers to binge four full seasons first; if Star City lands, you can imagine it doing for For All Mankind what Better Call Saul did for Breaking Bad or what Andor did for Star Wars.

It also helps that the release window is smart. A late May launch positions Star City to catch viewers who are between big spring finales and the heavier fall rush, especially those already in the Apple ecosystem via hit shows like Silo season three or the latest prestige dramas. A weekly cadence helps fuel word of mouth and theory culture that genre TV thrives on, giving fans time to pick apart alt history details and speculate on how events in this Soviet focused story might ripple back toward NASA in future seasons.

For longtime For All Mankind fans, the promise here is obvious: more of the same meticulous alt history worldbuilding, but finally told from inside the rival program that has been shaping the story from the shadows. For newcomers, the trailer plays almost like a standalone Cold War thriller – you could go in cold, understand the stakes, and then decide if you want to jump into the larger saga. Either way, Apple clearly wants Star City to be more than optional homework; it is pitching this as the next big sci-fi drama in its lineup, with rockets, secrets, and a whole lot of pressure building under that sealed Soviet sky.
