The Expanse (TV series)

The Expanse is an American science fiction television series developed by Mark Fergus and Hawk Ostby, based on the series of novels of the same name by James S. A. Corey. The series is 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), police detective Josephus Miller (Thomas Jane), 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 state of cold war.

The Expanse has received critical acclaim, 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. Ahead of the fifth season's release, Amazon renewed the series for a sixth and final season in November 2020, which is scheduled to premiere on December 10, 2021.

Hundreds of years in the future, the Solar System has been colonized by humanity. 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 confederation of the asteroid belt and the moons of Jupiter and Saturn.

Season 1

Chrisjen Avasarala, a United Nations executive, works to prevent war between Earth and Mars. Ceres police detective Joe Miller is sent to find a missing young woman, Julie Mao. The space-freighter Canterbury and the Martian Navy flagship Donnager are destroyed by Unknown Stealth Ships. James Holden, Naomi Nagata, Alex Kamal and Amos Burton escape in a Martian gunship named the Tachi. They subsequently rename the ship Rocinante which becomes the main setting of the series. The crew of the Rocinante, with Miller's help, investigates and eventually discovers a biohazard that kills off most of the humans on the asteroid Eros, including Julie.

Season 2

Martian Marine Bobbie Draper fights an inhuman figure on Ganymede and later, during peace talks between Earth and Mars, becomes a protégé of Avasarala instead. 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 completely disassembled 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 gets reunited with his daughter. The protomolecule forms the Ring, a structure which takes an orbital position beyond Uranus, and the race begins between all three governments to send their ships through. After a crazy Belter racing ship slingshots through the Ring at high speed, the ring believes the high speed humans and objects to be dangerous. Through Miller, Holden tries to shut off this low speed rule of the ring, and convince the protomolecule that humanity is not a threat.

Season 4

A large rush to other solar systems with habitable worlds opened up, accessible now via the Ring. 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 that has been settled by these Belter refugees, called Ilus. The settlers have been joined by an officially backed scientific expedition with private military support, often leading to violence between the two groups. The crew tries to ease the tensions, but fails, and decide to find out what is happening on the planet and where the previous civilization has gone. With the help of Miller, Holden reactivates the ancient structure, setting off a chain of cataclysmic events. Efforts to terraform Mars also begin to wane as ready-made habitable worlds are now available, as Bobby Draper realizes.

Season 5

A deadly conspiracy threatens Earth, as the crew of the Rocinante pursue personal missions while their ship is in drydock 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 amasses a Belter fleet, and attacks Earth through stealth shielded asteroids.

Season 6

The six-episode sixth season will premiere on December 10, 2021.

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 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.

Ahead of the fifth season's release, Amazon renewed the series for a sixth and final season, on November 24, 2020. 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.


On August 21, 2014, Thomas Jane, Steven Strait, and Shohreh Aghdashloo were attached to the series as Joe Miller, James Holden, and Chrisjen Avasarala. 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. Additionally, Anvar will not return for the sixth and final season after receiving multiple sexual misconduct allegations.


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.


The show's soundtrack was composed by Clinton 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.

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. Prior to the series premiere, Mark Fergus spoke of the series' 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 has "space western vibes".


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.


Critical response

Season 1

On Rotten Tomatoes, the first season has a score of 78% with an average rating of 7.10 out of 10 based on 45 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' stereotypical characters but credited it with tackling "issues of class, representation and exploitation" and a convincing design. At, 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." The season received a rating 91 out of 100 on Metacritic based on reviews from 4 critics indicating "universal acclaim". Writing for Den of Geek, Michael Ahr gave it a 5/5 review and wrote, "With its brilliantly crafted, multilayered plot, The Expanse season four proves itself worthy of Amazon's rescue in a nearly perfect season." Sadie Gennis of TV Guide also praised the fourth season, giving it a score of 4.5/5.

Season 5

On Rotten Tomatoes, the season has a score of 100% with an average rating of 8.8 out of 10 based on 30 reviews. The site's critical consensus reads, "The Expanse's many threads come to a head in an excellent fifth season that expertly capitalizes on everything that makes the show work while setting the stage for an epic final season." The season received a rating 82 out of 100 on Metacritic based on reviews from critics 5 indicating "universal acclaim".

Aftershow and podcast

Beginning December 16, 2020, Wes Chatham and Ty Franck started hosting weekly programs that feature behind-the-scenes information about the series, first as The Expanse Season 5 Aftershow after each season's episode. Then, after season aired, they continued on Wednesdays as audio/video Ty & That Guy Podcast, covering each series' episode, from The Expanse S1E1, additionally discussing their inspirations from genre culture and occasionally on other days of the week having guests, not related to the series.
