The For All Mankind universe, Apple TV+’s sprawling alternative-history epic, has always operated on the currency of “what if.” By diverging from real-world history at the moment the Soviet Union landed the first man on the moon, the series established a butterfly effect that has spanned decades, continents, and eventually, planetary bodies. Now, with the premiere of the highly anticipated prequel series Star City, showrunners are peeling back the layers of the early Cold War space race, offering a granular look at the Soviet side of the lunar divide.
While the show is ostensibly a character-driven drama about the men and women behind the Iron Curtain, astute viewers have begun to notice a recurring pattern in the nomenclature. As the series progresses, a compelling theory has emerged: Sasha Polivanov, one of the primary cosmonauts introduced in the early episodes of Star City, may be the biological father of the beleaguered Martian Governor Leonid Polivanov, a pivotal figure introduced in For All Mankind Season 5.
Main Facts: A Generational Space Odyssey
The narrative architecture of Star City is designed to mirror the intensity of the For All Mankind Season 1 zeitgeist, albeit through a Russian lens. We are introduced to a cast of characters who are, in many ways, the inverse of the American dreamers we saw in the parent series. Where the Americans had the cocky, media-savvy Ed Baldwin, the Soviets have a complex roster of ambitious, often ruthless, and highly disciplined figures.
Among these is Sasha Polivanov, portrayed by Solly McLeod. Sasha enters the narrative as a daring, albeit somewhat reckless, cosmonaut. He represents the "new guard" of the Soviet space program—technically proficient but prone to the kind of human error that the rigid Soviet system attempts to crush.
The crux of the theory lies in the timeline and the shared surname. For All Mankind Season 5 introduces us to Leonid Polivanov (played by Costa Ronin), the embattled governor of Mars. Leonid is a man defined by the weight of his office, struggling to maintain order as the Martian revolution begins to boil over. Given that Star City is set in the 1960s and For All Mankind Season 5 is set in the 2010s, the age gap is mathematically sound for a father-son dynamic.
Chronology: Bridging the Decades
To understand the likelihood of this connection, one must look at the timeline of the Soviet space program as established by the For All Mankind universe.

- The 1960s (Star City): Sasha Polivanov is in his prime, a young, bachelor cosmonaut tasked with pushing the boundaries of Soviet reach. His narrative arc is currently dominated by his forced, state-mandated marriage to Anastasia Belikova (Alice Englert), the Soviet Union’s first woman on the moon. This marriage is not one of affection, but of optics—a strategic move by the Soviet government to create a "power couple" of the stars.
- The 1970s–1990s (The Intervening Years): This period in the franchise’s history is filled with the expansion of the lunar colonies and the political instability of the USSR. If Sasha and Anastasia were to have a child during this window, that individual would be coming of age exactly when the space race transitioned from a sprint to a long-haul colonial effort.
- The 2010s (For All Mankind Season 5): Leonid Polivanov is established as a former cosmonaut turned politician. This trajectory—from the cockpit of a spacecraft to the halls of Martian governance—is a classic trope in the For All Mankind universe, where the “hero” astronauts of the past inevitably become the bureaucratic or political leaders of the future.
Supporting Data: The Evidence in the Details
The strength of this theory does not rest solely on the shared surname, though in a show as meticulously crafted as For All Mankind, surnames are rarely accidental.
The Career Path
Leonid Polivanov is explicitly stated to have a history as a cosmonaut. For a character to rise to the level of Martian Governor, he would need the prestige of a storied career in the Soviet/international space program. If Sasha Polivanov is indeed his father, it stands to reason that Leonid would be raised in an environment where the "culture of the stars" was the family business. The pressure to live up to a father who was a pioneer of the early space race would provide an excellent psychological foundation for the character we meet in Season 5.
Strategic Casting and Narrative Echoes
The showrunners have demonstrated a penchant for "re-introducing" legacy characters. We have seen characters like Sergei Nikulov reappear in later seasons, playing significant roles in the shifting geopolitical landscape. By placing a "Polivanov" in the 1960s and another in the 2010s, the writers are clearly inviting the audience to draw a line between the two.
Furthermore, the character of Sasha is currently defined by his volatile relationship with his wife, Anastasia. If the writers choose to introduce a son into this toxic domestic environment, it would heighten the dramatic stakes for Star City, showing us the generational trauma that creates the stoic, perhaps even cold, political figure that Leonid becomes on Mars.
Official Responses and Creative Direction
While Apple TV+ and the creative team behind the For All Mankind franchise—headed by Ronald D. Moore, Ben Nedivi, and Matt Wolpert—have remained tight-lipped regarding specific character backstories, they have been vocal about the "shared DNA" of the two shows.
In recent interviews, the producers have emphasized that Star City is not merely a spin-off but a fundamental expansion of the For All Mankind lore. "Everything we put on screen in Star City has a ripple effect," a representative for the production recently hinted. While they have not explicitly confirmed the Polivanov lineage, they have encouraged fans to pay close attention to the domestic lives of the cosmonauts, noting that "the personal is always political" in their version of the Cold War.
Implications: The Weight of History
If the theory holds true, the implications for both series are profound.

For ‘Star City’
This connection would transform Sasha Polivanov from a supporting character into a foundational pillar of the franchise’s long-term narrative. It would force the audience to view his reckless behavior and his forced marriage through a lens of inevitability. We are not just watching a man navigate the dangers of space; we are watching the patriarch of a family that will eventually shape the future of human habitation on Mars.
For ‘For All Mankind’
For viewers of the parent series, this revelation would add a layer of tragic irony to the Martian revolution. Knowing that Leonid is the product of the early Soviet space race—a time of optimism and brutal state control—makes his current struggle to govern a dying or rebellious colony feel more poignant. It suggests that Leonid is not just a politician; he is a man trapped by the legacy of his parents, tasked with managing the very expansionism that they pioneered.
Thematic Resonance
At its heart, the For All Mankind franchise is about the cost of progress. By linking a 1960s cosmonaut to a 2010s politician, the show is highlighting the cycle of history. The same idealism that drove Sasha to the brink of death in the early days of the space race is the same idealism that, when matured and hardened by years of bureaucracy, results in the complex, compromised leadership of the Martian colonies.
Conclusion
Whether Sasha Polivanov is confirmed as the father of Leonid Polivanov in the coming episodes of Star City remains to be seen. However, the pieces of the puzzle are laid out with such deliberate precision that it is difficult to see this as anything other than a planned connection.
As the show continues to drop new episodes every Friday, fans should keep a watchful eye on the personal milestones of the Polivanov household. In the world of For All Mankind, the smallest detail—a name, a date, a quiet conversation in a Soviet apartment—often serves as the spark for the next great revolution. For now, we are left to watch the stars, waiting to see how the sins and triumphs of the fathers are visited upon the sons, one orbit at a time.
