Project: Ganymede is a military science fiction television series created by Noah Hawley and Freddie Goodwin for Disney+. Set in the late 22nd century, the series follows humanity’s first colony on Ganymede, a brutal corporate-run frontier orbiting Jupiter. When a terraforming engineer uncovers alien ruins buried beneath the moon’s ice, her discovery ignites a rebellion that threatens to collapse the fragile economic and political balance of the solar system.

Produced by Mob Productions and 20th Television, the series stars Florence Pugh as engineer Mara Ellison, John Boyega as ex-marine Rhys Kellan, and Oscar Isaac as Governor Halden Varra. The ensemble cast also includes Giancarlo Esposito, Hailee Steinfeld, Dacre Montgomery, Riz Ahmed, Jessica Barden, Pedro Pascal, Willem Dafoe, Tessa Thompson, Toby Kebbell, and Mads Mikkelsen.

The first season, consisting of eight episodes, premiered on February 17, 2029, and concluded on April 7, 2029. The show received critical acclaim for its world-building, performances, and grounded depiction of interplanetary politics.

Premise

In 2179, Ganymede—once a barren moon of Jupiter—has become humanity’s most ambitious off-world colony. Corporations control its cities, mining its ice to supply water and fuel for the entire solar system. Beneath its frozen crust, engineer Mara Ellison discovers the remnants of a non-human structure emitting quantum signals. Her find threatens to expose decades of corporate secrecy surrounding Ganymede’s origins.

As riots erupt across mining sectors and rebel factions rise against the conglomerate TerraDyne Systems, Ganymede’s survival becomes a warzone of shifting loyalties and buried truths. The deeper Mara digs, the more she realizes that the alien ruins may not be remnants—but warnings.

No. in season	Title	Directed by	Written by	Original air date
1	"The Ice Beneath"	Noah Hawley	Freddie Goodwin & Lauren Schmidt Hissrich	February 17, 2029 (2029-02-17)
Terraforming engineer Mara Ellison oversees Sector 12’s subsurface reactor when a drilling array ruptures a sealed chamber beneath the ice, revealing impossible geometric structures. After the incident, her supervisor orders silence, citing “classified geologic anomalies.” Meanwhile, Ganymede’s private security force suppresses a miners’ strike led by Rhys Kellan, a disillusioned war veteran. As Mara investigates a strange signal emitted by the chamber, her systems begin to fail—until the signal suddenly responds to her heartbeat.
2	"The Fault Line"	Hiro Murai	Noah Hawley & Tom King	February 24, 2029 (2029-02-24)
After the reactor breach, Mara is quarantined and interrogated by Governor Halden Varra, who claims her discovery could destabilize the colony’s neural grid. Rhys and his miners are conscripted into “emergency labor duty” to contain radiation, uncovering more ruins in the process. The TerraDyne board on Earth debates a cover-up. When Mara’s AI assistant begins repeating phrases in an unknown language, she realizes the ruins are transmitting—not broadcasting.
3	"Icebreaker"	Cathy Yan	Freddie Goodwin & Bryan Edward Hill	March 3, 2029 (2029-03-03)
The alien structure begins to destabilize the ice crust, triggering quakes across multiple domes. Rhys rescues Mara during a collapse, and the two reluctantly join forces. They discover that the signal frequency matches data from a classified military project known as GANYMEDE PRIME—initiated decades before the colony’s founding. In orbit, Commander Selene Voss of the Earth Defense Council orders a blockade of the moon.
4	"Fracture Zone"	Gareth Evans	Noah Hawley & Lauren Schmidt Hissrich	March 10, 2029 (2029-03-10)
The blockade cuts off supply routes as civil unrest erupts in Ganymede’s lower sectors. Varra imposes martial law, while Mara and Rhys infiltrate a TerraDyne data vault to access geological records. They uncover evidence that the company discovered the ruins years earlier and used the alien structure as a reactor template. Mara uploads the data to a rebel broadcast, exposing the truth to the colony.
5	"Pale Signal"	Leigh Janiak	Bryan Edward Hill & Tom King	March 17, 2029 (2029-03-17)
With the colony in chaos, Mara follows the alien signal to a deep subsurface vault. Inside, she discovers stasis chambers containing fossilized non-human entities connected to a living neural lattice. Rhys is captured by corporate forces and forced to reveal the rebels’ hideout. On Earth, TerraDyne’s CEO authorizes “Operation Purity,” a full sterilization strike on Ganymede.
6	"The Drift"	Karyn Kusama	Noah Hawley & Freddie Goodwin	March 24, 2029 (2029-03-24)
As orbital railguns align for the strike, the alien network activates. Ganymede’s magnetic field collapses, cutting off all communications. Mara connects herself to the neural lattice, witnessing visions of the species that built it—creatures that once used the moon as a seed world. The signal expands, reaching Earth’s satellites and triggering mass power surges. Rhys and the rebels fight to evacuate civilians before the bombardment begins.
7	"Echo of the Sun"	Freddie Goodwin	Lauren Schmidt Hissrich & Tom King	March 31, 2029 (2029-03-31)
Mara awakens from the link with her consciousness partially fused with the alien network. She experiences time dilation across multiple possible futures, seeing Ganymede terraform itself autonomously. Varra’s fleet launches the sterilization strike, but the alien lattice redirects the energy into Jupiter’s atmosphere, creating an auroral storm visible from Earth. Humanity’s understanding of energy physics is shattered overnight.
8	"The Last Transmission"	Noah Hawley	Freddie Goodwin & Bryan Edward Hill	April 7, 2029 (2029-04-07)
Ganymede’s surface is reborn as a living biosphere, with alien flora spreading across the ice. The survivors rebuild under a new dawn. Mara’s body is missing, but her voice continues through the lattice—guiding the colony as both human and machine. In the final scene, an encrypted broadcast from Jupiter’s magnetosphere reveals a matching signal on Europa, suggesting the ruins were only the beginning.

Production

Development

Project: Ganymede was developed by Noah Hawley and Freddie Goodwin under Mob Productions in collaboration with 20th Television. The series was conceived as a grounded exploration of off-world colonization and corporate militarization in the 22nd century. Hawley described the show as "a space-western about survival, capitalism, and the lies we tell to call something home."

Principal photography began in early 2028 at Pinewood Toronto Studios, with extensive use of practical sets and volumetric LED environments for Ganymede’s domed cities. Gareth Evans and Karyn Kusama directed select episodes, bringing different tones to the militarized and existential halves of the story.

Themes

Hawley and Goodwin designed Project: Ganymede to contrast the idealism of colonization with the exploitation behind it. The alien ruins were intended not as invaders, but as a metaphor for humanity uncovering its own buried history—an ancient reflection of greed and survival. The series blends political drama with speculative science, emphasizing moral ambiguity and the cost of progress.

Release

The series premiered on Disney+ on February 17, 2029, releasing weekly until April 7. Marketing highlighted the show’s grounded tone and large ensemble cast, positioning it as a successor to hard science fiction dramas like The Expanse and Blade Runner 2049.

Reception

The first season received critical acclaim for its performances, atmosphere, and philosophical storytelling. Critics praised Florence Pugh’s portrayal of Mara Ellison and the show’s focus on scientific plausibility over spectacle. Some reviews noted pacing issues in mid-season episodes but commended the finale for its emotional weight and open-ended mythology.
