Apple TV has launched an alternate-history spin-off set in the same uniiverse as its flagship sci-fi series, shifting focus to the Soviet side of a never-ending Cold War space race. The show debuted with two episodes and earned a perfect 100% Rotten Tomatoes score, according to the report. Starring Rhys Ifans, Anna Maxwell-Martin,and Alice Englert, the series explores political intrigue, scientific ambition, and human cost from a perspective long absent from Western space dramas.

The perfect Rotten Tomatoes score that launched with two episodes

According to the news article, Apple TV's new series earned a flawless rating on a major review aggregator immediately after its two-episode premiere. That score indicates strong early approval from both critics and audiences, placing the spin-off in rare company. The report notes that the premiere was timed to follow the season five finale of Apple TV's inaugural sci-fi show, making the connection between the two programmes explicit from the start.

The perfect score is especially notable given the risk of retreading familiar alternate-history ground. By switching to the Soviet perspective, the series attempts to differentiate itself — and the early critical reception suggests it has succeeded, at least in the initial outing.

From Nixson to Gorbachev: Rhys Ifans, Anna Maxwell-Martin, and Alice Englert anchor the Soviet perspective

The cast is led by Rhys Ifans, who portrays the chief architect of the Soviet space programme — a character whose ambition drives the plot, as the report details. Anna Maxwell-Martin plays a seasoned KGB agent tasked with safeguarding secrets and navigating internal power struggles. Alice Englert brings youthful energy as a rookie cosmonaut confronting the dangers of early spaceflight and the political machinery around it.

These three characters intersect to illuminate Soviet politics, scientific innovation, and the human cost of an unending quest for dominance beyond Earth. The report emphasizes that the show's production values feature authentic period costumes, detailed sets, and cutting-edge visual effects, blending political thriller with adventure.

Why the alternate history space race that never ended mirrors today's geopolitical rivalry

The parent series first aired in 2019 as part of Apple TV's launch slate, alongside shows like The Morning Show and Dickinson. Over multiple seasons, it jumped from a 1970s setting to later eras with lunar colonies, Martian settlements, and private space enterprises — all in a world where the Space Race never concluded.. The spin-off adopts the same ambitious premise but from the Soviet vantage point, offering a commentary on the ideological clash that defined the late twentieth century.

The report notes that the broader saga of this alternate history universe is set to end in 2027 with a sixth and final season of the original series . That timeline gives the spin-off a limited runway to establish its own legacy before the parent story concludes.

A 2027 finale for the original series — and a spin-off trying to outlast it

The news article states that the original series will end in 2027 with its sixth season, closing the main narrative arc. Meanwhile, the spin-off is planned to run for several seasons, aiming to carve out its own place in the genre. This creates an unusual dynamic: the spin-off must build an audience and identity while tethered to a story that is already approaching its end.

The report does not specify whether the spin-off will continue beyond 2027 or if it shares the same endpoint . That unanswered question leaves room for speculation about Apple TV's long-term strategy for this alternate-history universe.

What the report doesn't say: the real Soviet space programme's dark corners

While the series promises to address the human cost of the space race, the news article offers no details on how it handles controversial episodes from Soviet space history — such as unreported failures, cosmonaut deaths,or political purges within the programme. It remains unclear whether the spin-off will confront these darker elements or lean into a more romanticised narrative.

Additionally, the report does not name the show's title, perhaps suggesting that Apple TV is keeping the branding under wraps or that the article itself omitted it. Either way, the lack of a title in the coverage is an unusual omission for a major streaming launch.
