The science fiction series The Expanse originally aired on Syfy before moving to Prime Video, running for six seasons between 2015 and 2022. This meant there was a time when both The Expanse and For All Mankind were in production simultaneously. However, because they were made by different companies, the two shows don’t share a connected storyline, and likely never will. As of 2026, that remains the case. Interestingly, even though For All Mankind continues to be made and doesn’t appear to be ending soon, it’s also unexpectedly helping to keep interest in The Expanse alive.
