Season Three is the third season of Syfy's The Expanse. It premiered on April 11, 2018, and continued airing each Wednesday until June 27, 2018, consisting of thirteen one-hour episodes. The twelfth and thirteenth episodes were aired together as part of a double-episode finale night. Syfy aired limited commercials that finale week in the U.S. market whereas Space in Canada ran normal commercials.

Production began in May 2017. The team began filming on July 12, 2017[4] and completed principal photography late in the night on December 5.[5]

The third season is based on the remaining half of Caliban's War and centers on Abaddon's Gate.


As the war between Earth and Mars ignites across the solar system, the terrifying next phase in the evolution of the protomolecule threatens the very existence of humanity. Caught in the middle, the Rocinante crew struggles to deal with tensions amongst themselves.
