For All Mankind: how did Molly Cobb die? The answer starts two seasons earlier

Here's the full timeline — it spans three seasons:

• Season 1 — Molly becomes the first American woman in space and on the Moon with Apollo 15. A trailblazer, partly inspired by real-life aviator Jerrie Cobb of the Mercury 13.
• Season 2 — A solar storm on the lunar surface leaves Molly with a lethal radiation dose and progressive blindness.
• Season 3 — Blind and sidelined from NASA, Molly is called back for one last job — and doesn't make it out alive.

The solar storm (season 2)

In the season 2 premiere, set in 1983, a massive solar flare hits the Moon while Molly and Dutch astronaut Wubbo Ockels are out on the surface, too far from base to make it back. Molly reaches a lava tube for shelter — but sees Wubbo's rover has flipped, leaving him injured and exposed. She leaves her radiation dosimeter badge behind in the cave and goes out into the storm to drag him to safety.

It's a decision that defines everything that follows. Molly absorbed an enormous dose of radiation — the show deliberately never specified exactly how much — and because she left her badge behind, no one knew the true extent of it. She developed normal-tension glaucoma as a direct result. Her eyesight deteriorated across the rest of season 2, and by the time season 3 picks up in the early '90s, she's fully blind.

"I don't know that she's had a death sentence per se," executive producer Ronald D. Moore told TVLine, "because we are also positing advances in technology."

Technology wasn't the problem. The bomb was.

The JSC bombing (season 3 finale )

In the season 3 finale, "Stranger in a Strange Land," a domestic extremist group — including the wayward Jimmy Stevens — detonates a bomb at the Johnson Space Center. Karen Baldwin (Shantel VanSanten) is killed in the blast. Molly, who'd been called back into the building to help guide Ed Baldwin through a dangerous Mars landing, survives the initial explosion.

What happened next is where it hurts. Molly used her blindness as an advantage — she was already accustomed to navigating without sight, so the smoke and darkness didn't disorient her the way it did everyone else. She led survivors through the wreckage to safety, feeling along the walls.

Then, instead of leaving with them, she turned around and went back in.

Her death was confirmed off-screen, via a newspaper headline revealing that her body had been recovered seven days later.

Why was it off-screen?

Executive producer Ben Nedivi explained in a 2022 CinemaBlend interview that the writers always intended to bring Molly back late in season 3 and felt her death carried more weight when delivered through the quiet reveal of the headline rather than a dramatic on-screen scene. The rebuilt space centre was renamed the Molly Cobb Space Center — a pointed detail, given that the real Jerrie Cobb, who partly inspired the character, was once barred from entering NASA's doors as an astronaut.

The woman who wasn't allowed in now has her name on the whole building.
