The Expanse is an American science fiction television series developed by Mark Fergus and Hawk Ostby for the Syfy network and is based on the series of novels of the same name by James S. A. Corey. Set in a future where humanity has colonized the Solar System, it follows a disparate band of protagonists – United Nations Security Council member Chrisjen Avasarala (Shohreh Aghdashloo), cynical detective Josephus Miller (Thomas Jane), and ship's officer James Holden (Steven Strait) and his crew – as they unwittingly unravel and place themselves at the center of a conspiracy that threatens the system's fragile peace, while dealing with existential crises brought forth by newly discovered alien technology.

The Expanse received positive critical response, with particular praise for its visuals, character development and political narrative. It received a Hugo Award for Best Dramatic Presentation and three Saturn Award nominations for Best Science Fiction Television Series. Syfy cancelled the series after three seasons. Amazon later acquired the series, producing three more seasons, with the series concluding with its sixth. The series premiered on December 14, 2015 on Syfy, with the series finale being released on Amazon on January 14, 2022.

Setting

Hundreds of years in the future, humanity has colonized the Solar System. The three largest powers are the United Nations of Earth and Luna, the Martian Congressional Republic on Mars, and the Outer Planets Alliance (OPA), a loose political confederation of colonies scattered across the asteroid belt and the moons of Jupiter and Saturn. The United Nations is a militaristic, ultra-capitalist society with authoritarian undertones, while the Martians have evolved into a corporatist culture. Both ruthlessly exploit and oppress the "Belter" populations of the OPA to gain control of their valuable natural resources.

Season 1

UN Deputy Undersecretary Chrisjen Avasarala works to prevent simmering tensions between the United Nations and Mars from erupting into all-out war. Ceres police investigator Josephus "Joe" Miller is tasked with finding a missing young woman, Julie Mao, who has ties to the OPA. The Canterbury, an industrial ice-harvesting ship, and the Martian Navy flagship Donnager are destroyed by unknown stealth ships. James Holden, Naomi Nagata, Alex Kamal, and Amos Burton survive both attacks and escape in the Tachi, a Martian gunship. They rename the ship Rocinante, which becomes the main setting of the series. The crew of the Rocinante, with Miller's help, investigate and eventually discover a biohazard that kills off most of the humans on the asteroid spaceport Eros, including Julie. Chrisjen sends her family away after realizing that a faction within the UN is responsible for the demise of both ships.

Season 2

The crew of the Rocinante, along with members of the OPA, attack the station responsible for the biohazard on Eros. Learning that it is an extra-solar bio-weapon known as the protomolecule, they attempt to destroy Eros. Miller becomes trapped there and dies when it crashes into Venus. Martian Marine Bobbie Draper fights an inhuman figure on Ganymede and later, during peace talks between Earth and Mars, becomes a protégé of Avasarala. The crew tries to help a father, Prax, find his daughter. In the process, they encounter and kill a figure akin to the one that Draper fought, now known as a "protomolecule hybrid", developed by Jules-Pierre Mao. A research ship, sent to Venus to investigate the crash of Eros into the planet, is stopped dead in the atmosphere and dismantled by the protomolecule.

Season 3

The UN declares war, as Earth and Mars send science vessels to investigate what is happening on Venus. Political tensions soar as the OPA is recognized as the government of the Belters and Prax is reunited with his daughter. The protomolecule forms the Ring, a structure which takes an orbital position beyond Uranus, and all three governments race to send their ships through. After a Belter racing ship slingshots through the Ring at high speed, the ring believes the high speed humans and objects to be dangerous and activates defenses that threaten humanity. Through Holden, a projection of Miller tries to shut off the defenses of the ring and convince the protomolecule that humanity is not a threat. The ring reveals itself to be a massive network of wormholes to other solar systems, each containing a habitable earth-like planet.

Season 4

A land rush to other star systems with habitable worlds begins, with thousands of planets accessible via the Ring's wormholes. Refugee ships from the Belt and overcrowded Earth are stopped at the gateway. A ship runs the blockade, and the crew of the Rocinante are sent through the portal to investigate the situation on the exoplanet, called Ilus. The settlers have been joined by an officially backed scientific expedition with private military support, leading to frequent violence between the two groups. The crew fails to ease tensions and decides to find out what is happening on the planet and where the previous civilization has gone. With the help of Miller, Holden reactivates an ancient structure, setting off a chain of cataclysmic events. Efforts to terraform Mars wane as habitable worlds are available.

Season 5

A deadly conspiracy threatens Earth, as the crew of the Rocinante pursue personal missions while their ship is in dry dock at Tycho Station. Draper and Avasarala investigate the Martian military's ties to a growing threat from a rogue faction of Belters. Marco Inaros, the rebel leader, assembles a Belter fleet and attacks Earth with stealth-shielded asteroids.

Season 6

Holden and the crew of the Rocinante fight alongside the Combined Fleet of Earth and Mars to protect the Inner Planets from Marco Inaros and his Free Navy. The combined fleet, allied with the ships of Camina Drummer and other Belter forces, defeats Marco and the Free Navy by antagonizing an unknown alien presence. On a distant planet, a young colonist discovers animals that can resurrect her dead sibling.

Production

Development

The Expanse is based on the novel series of the same name by James S. A. Corey, a pen name of the authors Daniel Abraham and Ty Franck, who also serve as writers and producers for the show. The first novel, Leviathan Wakes (2011), was nominated for the Hugo Award for Best Novel and Locus Award for Best Science Fiction Novel. On September 4, 2013, The Expanse was optioned for television by Alcon Television Group. On April 11, 2014, Syfy announced a straight-to-series commitment to a television adaptation of the book series, and ordered the production of 10 one-hour-long episodes for the first season. On that date Syfy President Dave Howe commented: "The Expanse is epic in scale and scope and promises to be Syfy's most ambitious series to date". Mark Fergus and Hawk Ostby wrote the pilot and served as writers and showrunners alongside Naren Shankar.

Terry McDonough was revealed to be directing the first two episodes of the series in October 2014. In May 2015, before the first season aired, writing commenced for a second season, which was ordered in December 2015. The second season of The Expanse premiered on February 1, 2017. On March 16, 2017, The Expanse was renewed by Syfy for a 13-episode third season to air in 2018. Four digital comics based on the books and tying into the television series have been published by ComiXology. The first focuses on the origin of James Holden and was released February 1, 2017. The next three, highlighting the origins of other characters are: Naomi Nagata, released April 19, 2017; Alex Kamal, released May 24, 2017; and Amos Burton, released July 12, 2017. The show's title sequence was animated and directed by Australian studio Breeder and its VFX team.

Cancellation and renewals

Alcon Entertainment produces and finances the series. It sold three seasons to Syfy, which canceled the series in May 2018. Fans protested the cancellation, gathering over 100,000 signatures for an online petition. They lobbied Amazon Studios and Netflix to greenlight the fourth season and a crowdfunding campaign paid for an airplane to fly a "#SaveTheExpanse" banner around Amazon Studios. Celebrities including Wil Wheaton, George R. R. Martin, Patton Oswalt and Andreas Mogensen supported the campaign. Amazon Prime Video picked up the series for a fourth season, which was released on December 12, 2019. In July 2019, Amazon renewed The Expanse for a fifth season, which premiered on December 15, 2020.

On November 24, 2020, ahead of the fifth season's release, Amazon renewed the series for a sixth and final season. Filming started in late January 2021. However, the authors of the novels and writers on the series, Daniel Abraham and Ty Franck, have stated that they view season 6 as a "pause" rather than a conclusion and that Alcon Entertainment "is very committed to the IP", Alcon's Andrew Kosove and Broderick Johnson said that they are "considering all kinds of interesting possibilities". On October 8, 2021, it was announced that the sixth and final season would premiere on December 10, 2021.

In January 2023, it was announced that the continuation of the series, set between Babylon's Ashes and Persepolis Rising, would be adapted into a 12-issue comic book series, The Expanse: Dragon Tooth.

Casting

In July 2014, Thomas Jane was cast as Joe Miller. In August 2014, Steven Strait and Shohreh Aghdashloo's attachment to the series as James Holden, and Chrisjen Avasarala was announced. October of that same year, Dominique Tipper, Cas Anvar, Paulo Costanzo, and Wes Chatham were cast as Naomi Nagata, Alex Kamal, Shed Garvey, and Amos Burton while Jonathan Banks and Jay Hernandez were announced to be guest starring in the series. One month later, Shawn Doyle was cast as Sadavir Errinwright, while Chad L. Coleman and Jared Harris were cast in the recurring roles of Fred Johnson and Anderson Dawes, respectively. Frankie Adams was cast as Bobbie Draper for the second season in April 2016. On January 21, 2020, Keon Alexander, Nadine Nicole, and Jasai Chase Owens (who portray Marco Inaros, Clarissa Melpomene Mao, and Filip Inaros, respectively), were promoted to the main cast for the fifth season. Later, Lily Gao was cast in a recurring role as Nancy Gao for the fourth and fifth seasons, a candidate for UN secretary-general. Anvar did not return for the sixth and final season after being the subject of multiple sexual misconduct allegations.

Filming

Produced by Alcon Television and The Sean Daniel Company, principal photography on the first season started on October 29, 2014, in Toronto and concluded on March 27, 2015. The second season filmed between April 13, 2016, and September 12, 2016. Filming for season 3 began on July 12, 2017. In February 2019, cast member Lyndie Greenwood announced that the fourth season concluded filming. Filming for the fifth season began on September 23, 2019, and ended on February 21, 2020. Production on the sixth season took place between January 27, 2021, and May 7, 2021. It was impacted by COVID-19 pandemic restrictions, as was post-production of the fifth season.

Title sequence

The title sequence of the series has been lauded by reviewers for its ability to elegantly and wordlessly convey important information about the worlds in which the series takes place. The title sequence was created by Breeder, a motion graphics design studio in Brisbane, Australia. Drawing comparisons to the opening sequence of Game of Thrones, Jason Morehead of Opuszine notes that not only does it depict the development of Earth's expansion into the solar system, it introduces the viewer to the political dynamics within the series. "Earth is the old guard, intent on controlling the system and her former colonies; technologically advanced Mars is driven to become a paradise; and the Belt is fighting to keep from being treated as a second-class citizen by both Earth and Mars."

While the title sequence does change visually as the series progresses, the lyrics that accompany Clinton Shorter's title theme – written and performed by Lisbeth Scott – remain the same. Scott noted in a post on Facebook that her words were drawn from Norwegian, though she apologized for any errors in syntax, grammar and pronunciation.

Music

The show's soundtrack was composed by Shorter. The first season's soundtrack dubbed The Expanse Season 1 – The Original Television Soundtrack, consisting of nineteen tracks, was released by Lakeshore Records, on May 20, 2016, via iTunes, and on May 26, 2016, via Amazon.

Language

Main article: Belter Creole

The Belter characters speak Belter Creole, an invented language created for the show by linguist Nick Farmer; these characters speak English with a distinctive accent. As explained in one article, "People who have migrated to the Belt come from all over Earth speaking dozens of languages, and they're often isolated for years at a time on remote mining stations. To communicate, they evolve a creole called Belter, which becomes the lingua franca for what is essentially the solar system's new proletariat."

Release

The pilot episode was screened at San Diego Comic-Con in July 2015. In the United States, seasons 1 to 3 of The Expanse were broadcast by Syfy and streamed on Amazon Prime Video. In Canada, these seasons aired on Space and streamed on Crave. In New Zealand, these seasons aired on Sky. In all other countries where Netflix is available, seasons 1 and 2 were streamed until September 2018. On February 8, 2019, Prime Video took over exclusive distribution of the first three seasons worldwide in preparation for premier of the fourth season in 2019.

Reception

Critical response

Season 1

On Rotten Tomatoes, the first season has a score of 78% with an average rating of 7.1 out of 10 based on 46 reviews. The site's consensus states: "The Expanse blends sci-fi elements and detective noir into a visually compelling whole, though it takes a few episodes for the story to capture viewers' intrigue." The first season received a rating of 65 out of 100 on Metacritic based on reviews from 23 critics, indicating "generally favorable reviews". Reporting on the pilot screening, io9's Lauren Davis declared herself "blown away" by The Expanse, appreciating its "incredible sense of scale" and its "deeply thought out future world that reflects on our present one, with high production values and characters who speak and act like real people". Max Nicholson of IGN characterized the pilot as "grim and dramatic", and a "very dense hour of television", with the terminology and large cast sometimes difficult to follow for viewers unfamiliar with the novels, but highlighted the pilot's "gorgeous" visuals and effects reminiscent of Battlestar Galactica, Dune and Firefly. Writing for Variety, Maureen Ryan was unimpressed by the first four episodes "awkwardly linking a series of somewhat muddled stories" and the series's stereotypical characters but credited it with tackling "issues of class, representation and exploitation" and a convincing design. At Tor.com, Justin Landon highlighted The Expanse's "bold and unique cinematography" and its claustrophobic, discomforting set designs, as well as the "extremely faithful" characterization, but remarked that the patois spoken by the Belters, the natives of the asteroid belt, made the series difficult to follow.

Season 2

On Rotten Tomatoes, the season has a score of 95% with an average rating of 9 out of 10 based on 21 reviews. The site's critical consensus reads, "The Expanse's second season offers more of the show's excellent signature production values while increasing character development and politically thrilling narratives." On Metacritic, it has a score of 77 out of 100 based on 5 reviews. Writing for io9, Katherine Trendacosta noted how the show had become "shockingly prescient", insofar as many of the issues and ideas explored by The Expanse mirrored contemporary trends in global politics. Brian Tallerico, in "Why The Expanse Is the Best Sci-FI TV Show You're Not Watching" for Rolling Stone, praised the show for its contemporary political relevance and called its willingness to mix tones, and its protagonists, laudable. He summarized that at its core, The Expanse was all about people responding to fear – fear of the other, fear of the new, fear of inequality, fear of death. Writing for 13.7: Cosmos & Culture, a blog hosted by NPR, astrophysicist Adam Frank praised the show and its writers for the scientific realism. He wrote that "more than any other TV space-themed show, it gets the science right".

Season 3

On Rotten Tomatoes, the season has a score of 100% with an average rating of 8.6 out of 10 based on 26 reviews. The site's critical consensus reads, "Building on earlier potential and extending character arcs throughout a solidly crafted third season, The Expanse continues to impress – and shows no signs of abating." Michael Ahr of Den of Geek said the series "wowed fans with its complex characters, its political intrigue, its attention to scientific authenticity, and its stunningly good visual effects, and with several more books in the series that inspired the show, there's plenty more source material for the adaptation to explore in future seasons." Liz Shannon Miller of IndieWire praised the performances of Coleman and Strait in the absence of the Joe Miller character, saying "In general, while the mid-Season 2 departure of Joe Miller (Thomas Jane) and his wonderful hats does leave a bit of a vacuum, the ensemble has coalesced nicely, with both established performers like Chad L. Coleman and relative newcomers like Strait settling into their roles." Speaking about the premiere, Kevin Yeoman said, "All in all ... season three begins by dramatically raising the immediate stakes of the story without drastically altering the dynamics of the show itself."

Season 4

On Rotten Tomatoes, the season has a score of 100% with an average rating of 9 out of 10 based on 34 reviews. The site's critical consensus reads, "Smart and thrilling as ever, The Expanse's fourth season doesn't miss a beat, successfully navigating network changes without losing any of its rich character work or narrative complexities."

Scientific accuracy

The Expanse was widely praised for its scientific realism and technical accuracy, with executive producer Naren Shankar – a former PhD student in applied engineering – being credited for effectively applying his knowledge of physics and engineering. The show's depiction of stealth technology, uncontrolled decompression, the vacuum of space, and spacecraft propulsion were singled out for praise, with other reviewers arguing that the show effectively prepared viewers for future scientific developments.

Genre and themes

The series has been described as a space opera by critics. Emily VanDerWerff of Vox describes the first season of the series to be a "blend of science fiction and noir-infused detective drama, with a backdrop of political intrigue". Vice has referred to the series as a "sci fi noir mystery-thriller" and as hard science fiction. Opposed to the latter, the source books' authors defined their approach as aiming for a "Wikipedia level of plausibility". To complicate the plot, they kept inertia realistic, as well as light speed delay, which solved a "cellphone problem" for the show.

Prior to the series premiere, Mark Fergus spoke of the series's Western themes: "Everywhere is kind of back to the frontier rules so it gives us all that stuff back that we lost. Cellular technology. You can get a little more Western about it." The fourth season, according to the writers, also had "space Western vibes".

Analyzing the show, Tech Times wrote that The Expanse "...is more than just a science fiction show about people traveling the solar system in spaceships. It ... covers ... politics, poverty, oppression, discrimination, and the struggle for resources in harsh environments."
