The European Space Agency Co-Designed a Video Game About the End of Earth. It Launches April 28.

On April 28, 2026, the European Space Agency will release a video game. That sentence should stop you for a second. ESA, the same agency that landed Philae on a comet and is currently tracking the Artemis program from Darmstadt, put its name on a third-person action-adventure about two astronauts stranded on a hypothetical ninth planet. The game is called Aphelion, it is made by French studio Don’t Nod, and it is the first time a major space agency has publicly co-designed a narrative game from the ground up.

Most space games want you to blow things up. Aphelion wants you to survive a catastrophe that scientists think is plausible. That difference is the whole story.

The Premise Is a Peer-Reviewed Nightmare

The setup: by 2060, Earth is uninhabitable. Humanity’s last shot is Persephone, a theorized ninth planet at the edge of the Solar System. ESA sends the Hope-01 mission, two astronauts named Ariane and Thomas, on a one-way scientific expedition. The ship crashes. Ariane wakes up on the surface. Thomas is hurt. There is something out there that is not human.

Persephone is not a random sci-fi planet. It is lifted from the Planet Nine hypothesis, the astronomical theory that there is a massive undetected planet in the outer Solar System, nudging Kuiper Belt objects into weird orbits. Caltech researchers have been chasing this ghost since 2016. Don’t Nod wrote a game around it and handed the planetary stats to ESA physicists to stress-test.

Persephone’s published data sheet reads like a homework assignment: diameter 11,480 km, mass 4.77 × 10²⁴ kg (about 80 percent of Earth), gravity 0.8G, icy composition, a very long eccentric orbit. Those numbers are not flavor text. They dictate how Ariane jumps, how her suit behaves in vacuum, how light hits the ice.

Why ESA Said Yes to a Video Game

Space agencies do not co-develop entertainment products. They consult on documentaries, license footage, send astronauts to late-night shows. Actually sitting in a writers’ room with a narrative studio, reviewing scripts for scientific accuracy, is new territory. ESA’s public statement frames it as “grounding the depiction of space exploration in real scientific knowledge and humanistic values,” which is press-release language for “we wanted to stop Hollywood from inventing the laws of physics again.”

The practical side is recruitment. NASA has been panicking for a decade about the median age of its engineering workforce. ESA is in a similar spot. Gen Z kids do not grow up watching Apollo footage, they grow up watching streamers. If a kid spends 20 hours on Persephone and walks away thinking orbital mechanics are cool, that is a funnel ESA cannot buy with recruitment ads.

It also lines up with a real moment in space exploration. Artemis II just broke a 55-year-old distance record set by Apollo 13. The Moon is being remeasured in real time, with new craters being catalogued that erased older ones. Public appetite for space stories is back, and ESA would rather feed it with something accurate than watch Netflix produce another show where spaceships bank like airplanes.

Don’t Nod Is the Right Studio for This

If you picked a random AAA studio to make a game with the European Space Agency, you would probably get a cover shooter where aliens scream and the astronaut has a bionic arm. Don’t Nod is different. The Paris studio made Life Is Strange, Tell Me Why, Vampyr, and Banishers. Their portfolio is narrative-forward, emotionally heavy, often slow. They care about character interiority. They are famously allergic to bombastic action.

Their new trailer, aired at the ID@Xbox showcase on April 22, doubles down on that. It focuses on Ariane’s grief. It hints at the past relationship between her and Thomas. It shows her alone in vast frozen panoramas with an entity called the Nemesis hunting her from off-screen. This is a stealth-exploration game with action sequences, not a shooter with lore. The studio’s public pitch is that Aphelion sits at the intersection of exploration, traversal, and tense hiding, not combat.

There is a risk here. Narrative games have a weird relationship with commercial success. The Last of Us Online was killed when it was 80 percent complete because Sony could not model the live-service math. Aphelion is a linear, single-player, story-first product in a year when Ubisoft is remaking Black Flag with live-service hooks and Starfield is getting a second chance on PS5 via free weekends. A slow, sad sci-fi game about guilt and ice is not the obvious April 2026 hit. It is the bet.

The Literary Sci-Fi Lineage

Don’t Nod has been open about the references. Interstellar, The Martian, Ad Astra, Arrival. That lineup is not accidental. All four films treat space as lonely, cold, and scientifically uncooperative. All four have an astronaut confronting a personal emotional problem wrapped in a cosmic one. Aphelion is trying to port that mood into playable form.

The closest gaming ancestor is Alien: Isolation. Same stealth pressure, same “one creature you cannot kill, you can only evade.” The difference is tone. Isolation was claustrophobic horror in corridors. Aphelion is agoraphobic horror in wide frozen plains, under a sky that at 1000+ AU from the Sun would look nothing like Earth’s.

The Question Nobody Is Asking

Here is what makes Aphelion weird in the best way: the game assumes Earth dies. Not as a twist. Not as a surprise third-act reveal. The premise is that by 2060, we have already lost, and the last functional institution is ESA, trying a hail-Mary mission to a planet that might not even be there.

That is a dark starting position for an agency co-branded product. ESA did not have to sign off on “Earth is uninhabitable by 2060.” They could have asked for “Earth is badly damaged” or “Earth is evacuating” or any of the softer framings space agencies usually prefer. They did not. The pitch they approved is bleak.

Read that however you want. One reading is that ESA scientists, unlike ESA comms, are tired of dancing around the math on climate and biosphere collapse and wanted a mainstream narrative product to state the timeline in plain language. Another is that they just thought the story was good. Either way, a video game is about to drop with a space agency’s blessing that says, in not very coded terms, we have 34 years to figure something out.

The cat on the windowsill does not care about Planet Nine. He cares about the sunbeam moving across the floor. There is something honest about that. Ariane is going to spend her entire game trying to survive on a planet that may not exist, because the one that does exist has run out of time. The cat, meanwhile, is winning.

Aphelion launches April 28, 2026, on PC, PS5, and Xbox Series X|S. Day one on Game Pass. Physical edition in July. Bring a jacket.
