"The Expanse" space TV series may be over, but it still lives on as a fandom among astronauts as a video game prequel released on Thursday (July 27).

International Space Station astronaut Andreas Mogensen's love of the series came to light when "The Expanse" was canceled after Season 3 on its first network, Syfy. The Danish citizen wrote a tweet in May 2018, lamenting "Say it ain't so!" of the series' apparent demise. 

Mogensen told Space.com he found himself, unawares, joining a growing Twitter campaign to keep the series going as the showrunners shopped their concept to other buyers — which clearly worked as Season 4 aired in 2019 on Amazon Prime.

"I had just started watching 'The Expanse' and absolutely loved it, especially the attention to detail, especially when it comes to human physiology," Mogensen, a European Space Agency astronaut, told Space.com on Tuesday (July 25) during a press conference for his next mission, SpaceX Crew-7.

Crew-7 includes Mogensen, NASA astronaut Jasmin Moghbeli, Japan Aerospace Exploration Agency astronaut Satoshi Furukawa, and Konstantin Borisov of Russia's space agency, Roscosmos. The quartet will launch from NASA's Kennedy Space Center at 6:56 a.m. EDT (1056 GMT) no earlier than Aug. 17. You can watch the events live at Space.com, via NASA Television.

"The Expanse" ran on Syfy for its first three seasons and then Amazon Prime for its final three. It is based on a series of novels under the pen name James S.A. Corey (a joint effort of Daniel Abraham and Ty Franck). The novels and series alike follow the far future of humanity, when settlements are all over the solar system and coming into conflict with each other.

While the series finished for good in January 2022, a continuation started up Thursday in video game format."The Expanse: A Telltale Series" by Telltale Games will release five prequel episodes of the series between July and September for PlayStation 4/5, Xbox X/S/One and Microsoft Windows.

Mogensen will be in space while the video game is released, and didn't directly answer a Space.com question about whether he plans to do a rewatch of the series during his limited spare time. But he did praise the accuracy of the franchise.

"They had taken account of how our human bodies would be affected by being born and growing up in the asteroid belt," he said. "I thought that was really fascinating. It was one of the first science fiction series that I knew that had gone into that detail."

Mogensen wasn't the only astronaut asking for "The Expanse" to keep going. NASA astronaut Rick Mastracchio tweeted in 2018 during the save the series campaign during a break from supporting a cargo mission with Northrop Grumman's Cygnus spacecraft. (By coincidence, Mastracchio today works for Northrop Grumman.)

"It's an inspiring show and fun to watch. Check it out," Mastracchio tweeted.

Scientists working on NASA missions have also supported "The Expanse" over the years. For example: Robert Hurt, an astronomer who does visualizations for NASA at the California Institute of Technology (Caltech), did a space trivia contest with show cast members in 2019.

A 2017 public panel about the science of "The Expanse" featured several real-life scientists with agency connections, including Jessie Christiansen, an astronomer at the NASA Exoplanet Science Institute at Caltech, and Seth Shostak, a senior astronomer at SETI Institute (which regularly works with NASA.)
