For the better part of a decade, Apple TV+ has run an alternate twentieth century in which the Soviet Union reached the Moon first and the space race never stopped. Star City picks up that universe and crosses to the other side of it, telling the story from behind the Iron Curtain, from inside the program that, on our own timeline, came in second.

The series is the first spin-off of For All Mankind, and it trades Houston mission control for the closed Soviet world of cosmonauts, engineers and intelligence officers racing to put a hammer and sickle on the Moon. Rhys Ifans leads the cast as the Chief Designer, the position whose real occupant the Kremlin kept classified for years, the man asked to turn political promises into rockets that actually fly.

Star City comes from Ben Nedivi and Matt Wolpert, the writing partners who have steered For All Mankind season to season, working again with franchise co-creator Ronald D. Moore. The production is built by Sony Pictures Television with Moore’s Tall Ship Productions, the same creative core that turned a single counterfactual, a Soviet cosmonaut beating Apollo to the lunar surface, into one of streaming’s most durable science-fiction sagas. Moore brings the instincts that shaped Battlestar Galactica and Outlander: history bent just far enough to expose how people behave under impossible pressure.

A space race told from the side that lost

For All Mankind always watched the Cold War from the American hangar, where the shock of finishing second became the fuel that kept NASA reaching. Star City removes that comfort. The audience now sits with the engineers in the secret city outside Moscow, where success was a state secret and failure could end a career or a life. The Chief Designer has to keep a program running under the eyes of the Party while sending people into orbit on hardware no one outside the walls is allowed to see.

That vantage gives the show a different texture from its parent. It plays as a Cold War drama as much as a space story, full of surveillance, internal rivalry and the gap between what the Soviet program announces and what it can actually build. The title points at a real place. Star City, north-east of Moscow, is the settlement that trained the first humans to leave the Earth, and the series uses it as the pressure chamber where myth and machinery collide.

The faces inside the program

Around Ifans, the ensemble is built from the people official history rarely named. Anna Maxwell Martin plays Lyudmilla Raskova, Agnes O’Casey is Irina Morozova, Alice Englert appears as Anastasia Belikova, and Solly McLeod plays Sasha Polivanov. Their stories run from the launch pad to the listening posts, weaving together the cosmonauts who fly, the officers who watch them, and the families who are told almost nothing.

The casting leans on character actors rather than marquee names, which suits a show about a system that buried individuals beneath the collective myth. The drama lives in the distance between the public heroes the state needs and the private people who carry the risk, often without permission to feel afraid.

Where it sits in the For All Mankind universe

Star City shares its world with For All Mankind but stands on its own. A viewer who has never seen the original can start here, because the premise is clean: the Soviets are ahead, and the people inside the program know exactly how fragile that lead is. For returning fans, it fills in the half of the race the flagship series could only watch from across the ocean, and it does so without asking anyone to memorise a timeline first.

The alt-history engine stays intact. One changed outcome in 1969 still ripples outward, but here the ripples move through Moscow rather than Houston, reshaping careers, marriages and loyalties on the winning side of a contest that, in our world, ended the other way. The familiar question of the franchise, what would have happened if, gets a sharper edge when the answer belongs to the rival.

The first season runs eight episodes, releasing weekly rather than all at once, and carries a TV-MA rating that matches the franchise’s adult, politically charged tone. It arrives as Apple TV+ keeps building its identity around prestige science fiction, the genre that has given the service several of its most talked-about originals and a reason for viewers to stay between seasons.

The real test is tonal. For All Mankind asked American audiences to feel the sting of losing and then to cheer the comeback. Star City asks something stranger: to sit on the far side of that same race and want the people there to succeed. Whether an audience raised on the home team can make that switch is the question the new series quietly opens, and the one it has eight hours to answer.
