For All Mankind S3E3 Review: The Race Hardens Into a Blackmail
The three-way scramble to Mars compresses two years of schedule into eight months, and the season's quiet love story turns into a coercion file.
For All Mankind has always argued that ambition and damage are the same engine running in two directions. The third season’s third hour pushes that thesis hard. NASA, Helios, and the Soviet Union are now all launching for Mars in 1994, two years ahead of plan, and the people who have to make that math work — Margo Madison, Ed Baldwin, Danielle Poole, Aleida Rosales — get pulled into decisions that look like opportunity until the next scene shows what they cost. By the time three rockets light their engines in the same two-week window, the show has quietly converted its longest-running professional friendship into a national-security crime.
A schedule cut in half by political vanity
The cold open sets the stakes by reframing what we thought was a Mars race. Helios announces a 1994 launch. President Hart, who inherited Reagan’s NASA from the season’s first hour, refuses to come in second. Wrenn Schmidt’s Margo Madison walks into a conference room full of engineers and tells them Sojourner 1 will be ready in two years instead of four. Bill Strausser calls it building the Parthenon in a day. Aleida Rosales has the answer in her notebook: launch the pre-supply outside the standard window, slingshot it past Venus, and let MIT’s published trajectory math do the rest. It is the kind of save the show treats as routine for its engineering protagonists, and it lands the way every Aleida save lands — quietly, before the room has noticed she has solved it.
The political theater around the decision is where the hour first shows its teeth. A presidential debate clip puts Governor Clinton against the incumbent on whether Mars-rushing is worth billions when food programs exist. The Soviet announcement, delivered through a translator who quotes Lenin about workers of the world, is staged as the third party in a competition that two years ago was a two-horse race. The show keeps cutting to network anchors framing this as a sprint. The engineers know it is a forced march, and they know the forced march is the point — the political class needs the picture of three rockets in the same sky more than it needs any single mission to succeed.
Phoenix learns to listen to its commander
The Phoenix walkthrough scene is the episode’s most quietly important hand-off. Joel Kinnaman’s Ed Baldwin tours the Helios ship with Edi Gathegi’s Dev Ayesa, who is selling him on gourmet MREs and fifteen crew slots and the idea of putting a poet on Mars. Ed laughs at the poet. He does not laugh when Dev tells him the flight control systems are fully automated and the only pilot the ship technically needs is its commander. Ed’s response is the speech the season has been waiting for him to give. Thirty million miles from Earth, eight-minute comms lag, system failure means improvise or die. Dev listens. Then he walks onto the assembly floor and tells the crew to stop building. He says he made a mistake. They will rework the flight systems per the commander.
This is the show’s first sustained look at how the Helios collective actually behaves under pressure, and Dev’s posture — public correction, no defensiveness, immediate cost absorbed — is meant to read as the opposite of how NASA’s bureaucracy would handle the same disagreement. The episode is not naive about it. Dev’s collective is also the place that just offered Karen Baldwin a recruiting role and watched her flip a NASA engineer in an afternoon. The flat hierarchy works because the money is generous and the founder is charismatic, not because the model has been stress-tested. But the scene gives Ed a reason to believe the choice he already made was right, and it gives the audience a clean contrast to the next forty minutes of NASA’s internal damage.
Karen and the cost of being Margo’s girl
Shantel VanSanten’s Karen Baldwin walks into the Outpost and offers Aleida Rosales a hundred thousand a year, double her NASA salary, plus stock options, plus the Helios pitch about no titles and no decrees from above. Coral Peña plays the moment as recognition rather than temptation. Aleida points at her shelf, at the moon rock Margo arranged for her to receive, and tells Karen that being known as Margo’s girl is a small price to pay for having come from Parras de la Fuente and ended up holding lunar regolith. Karen takes the no with grace. The scene works because it is not really about money. It is about whether the person who saw you first deserves your loyalty when the person who sees you now is offering more.
The B-side of the same conversation goes the other way. Karen finds Bill Strausser later, and Bill says yes. The episode lets us watch Aleida find out he is leaving in the trench, surrounded by photos of his first day at NASA, and the goodbye is the episode’s most tender beat. Bill calls himself an old shoe. He says Karen called him a “get” and admits how good that felt to hear after thirty years of being the guy the room takes for granted. He tells Aleida she is going to be a great flight director. The show is not punishing him for leaving. It is making the point that Margo’s circle does not hold everyone equally, and that the founders’ generation has been so focused on the mission that some of the people building it have been quietly starving for recognition.

The Sergei trap closes on Margo
The season has been threading Margo’s IAC encounters with Sergei Nikulov as the show’s slowest-burn romance, going back to the moon-base detente of season one. This episode pays off the eight-year flirt in the cruelest way the show could have chosen. They meet in London at the IAC. They drink. Sergei asks to use her hotel restroom and walks out of it asking her to kiss him. The scene is gentle. She says yes. He stops, breathes shakily, and asks her for the Sojourner nuclear engine design, because the Soviet cooling system is failing, because his superiors will not accept missing the 1994 window, because the only way they stay relevant is to launch.
Margo says no. The refusal is the cleanest line Wrenn Schmidt has been given all season. Anything nuclear is outside the scope. She does not want another Buran. She tells him she is sorry and she leaves. Then the show pulls the rug. A KGB agent knocks on her door, walks Sergei into the room, and lays out nine years of classified information she has passed to him “in the interest of space travel and international peace.” She refuses to be blackmailed. The agent, played with surgical politeness, then has Sergei choked in front of her until she is begging him to stop. He hands her a phone number. He tells her to take a day.
This is the hour’s pivot. The Sergei plotline was the show’s argument that two engineers on opposite sides of the Cold War could push each other’s programs forward in good faith. The agent’s monologue about Korolev and the gulag reframes that decade of trust as a recruitment file. Margo returns to Houston, tells her assistant to cancel a record-store order and refuse a cabinet secretary, and the next scene is the rocket launches. The show does not yet say what she will do with the phone number. It says she now lives inside a problem with no clean exit.
What this episode argues
The hour’s argument is that the people the public will remember as the heroes of Mars ‘94 are already paying private prices the public will not see. Ed gets the ship he wants and loses Kelly to NASA in the same dinner. Danielle pulls Danny’s flight status to save his life and is overridden by Ed within hours. Aleida turns down generational money and loses her oldest workplace friend the same week. Margo refuses to sell her engine and is told the friendship that defined her career was an intelligence operation. The launches at the end of the hour are the show’s victory lap, and the show stages them over a Soundgarden track because it knows the victory has already cost more than the audience has been told.
Underneath that is a quieter argument about what kind of person Mars is going to belong to. Ed brings Danny Stevens onto Helios because Karen and Ed cannot bear to let Gordo’s kid sit in a Houston jail. Kelly tells her father she needs to do this on her own. Danielle warns Ed that not everything can be cured by a trip to outer space. The founders’ generation is making rosters out of grief and loyalty. The younger generation is making them out of science. The show has not yet told us which set of choices will survive the trip, but it has begun to grade them.
Verdict
This is the episode where season three commits. The two-year schedule compression gives every plot a clock. Phoenix earns its commander a real chair on the flight deck. Sojourner gets the trajectory it needs. Helios poaches the engineer NASA could not afford to lose. The Sergei reveal is the kind of move the show has been quietly setting up for two seasons, and the staging — the gentle bathroom proposition, the immediate ask, the agent waiting in the corridor — gives Margo a corner she has never been in before. Krys Marshall continues to be the conscience of the hour, and the late beat where she begs Ed not to put Danny on Helios is the most honest scene the show has written about what astronaut-family solidarity actually breaks under.
A few seams show. Danny Stevens’s pool-trespass arc is staged efficiently but lands as a checklist of the warning signs the show needs the audience to register before the season’s later choices about him pay off. Kelly’s pivot to NASA is sold by Cynthy Wu without much runway to ground it. And the triple-rocket-launch montage is the kind of crowd-pleaser this series can do in its sleep. None of it overrides what the hour pulls off. The race to Mars has hardened from a slogan into a coercion file, and the people building the ships are about to find out what they signed.
Rating: 8.6/10
