The Expanse is a TV show based on the science fiction book series of the same name by James S.A. Corey.

Set 200 years in the future, humanity has colonised the solar system. With Mars and Earth on the brink of war, the OPA (Outer Planets Alliance) is caught in the middle, fighting for Belter rights. Characters from various factions are drawn into a conspiracy that threatens all of humanity, as they try to protect their own people.

On Ceres, Detective Joe Miller searches for a missing Earther Julie Mao. Meanwhile the crew of the Canterbury discover a new threat when responding to a distress beacon on an abandoned ship.

The Expanse is often described as a critically acclaimed show, with a cult following particularly among members of the STEM (Science, Technology, Engineering and Mathematics) community. A large amount of fan activity focuses on discussion of theories, episodes and characters; with fans of the books and TV series organising on sites like Reddit.

Fans of show often refer to themselves and their fandom as Screaming Firehawks. It's a name that character Alex Kamal originally suggested in canon, for the ship that eventually became the Rocinante.

Cosplay is a popular activity among Expanse fans. Many cosplay their favourite characters at conventions, with Mars, OPA and Cantebury uniforms common. In October 2018, fan Christina Ward organized The Expanse Cosplay Week 2018 on Twitter. Submissions were taken on Twitter using the hashtag ExpanseCosplayWeek2018. See @ExpanseCosplay.

The Expanse Fandom Exchange was organized by Tumblr user the-roci in 2018. The exchange was open to several different types of creative format, including fics, gifsets, fanart, playlists and vids. See Announcement post.

#Save the Expanse

Midway through the third season, Syfy announced that it would not be renewing The Expanse for a fourth season. Many reports suggest that the decision was influenced by the fact Syfy did not hold the streaming rights for the series, and not enough fans were watching the show live.

Fans immediately began to organise a campaign to save the expanse. An online petition encouraging Netflix or Amazon to pick up the series gained over 130,000 signatures. Crowdfunding campaigns raised money to fly a Save the Expanse banner over Amazon studios, and to launch a model of the Rocinante ship to the edge of space.[1] Several celebrities who are Expanse fans, including George R.R. Martin, Will Wheaton and Patton Oswalt, tweeted their support for the series.[2]

The cast and crew of the Expanse were also very active on social media during this time, particularly Cas Anvar who plays Alex; thanking fans for their campaign and encouraging live viewings.

Amazon picked up the Expanse season 4 in May 2018.[3] In July 2019, the streaming service gave the series an early renewal for a fifth season, before its fourth season had aired, leading to much fan speculation.[4]

Common Tropes & Storylines

  • Martian Sponsorship Programme AU: A very small number of works employ this AU setting, which was originally created by Szcay. In this AU, Mars lost the war against Earth. Martian expatriates are now required to have an Earther sponsor in order to work and live outside Mars. These works can be dark fics and resemble Slavery AUs.


Examples Wanted: Editors are encouraged to add more examples or a wider variety of examples.


  • White Collar War Crimes by Szcay, An AU where the protomolecule has been destroyed, but it has already disturbed the balance of the system. Earth and Mars are launched into war, lasting only a few bitter months before Mars is defeated. Now the unchallenged masters of the system, Earth demands reparations from the defeated nation that affects the crew of the Roci in ways they couldn’t imagine. (Amos Burton/Alex Kamal)
