The Expanse (2015)

Earth, Mars and the Belt are one bad decision away from open war, with the United Nations and Mars exploiting the Belters for their resources. The military heart is Bobbie Draper, a Martian Marine Corps gunnery sergeant, and the main crew fly a captured Martian gunship they rename the Rocinante. Syfy canceled it after three seasons, Amazon picked it up, and it finished on its own terms with a sixth season, 62 episodes in all. It also won three Hugo Awards for Best Dramatic Presentation. Season one is a slow-building mystery; stick with it.
