Nevertheless, this is history in the making. Martin-Green is the first black woman ever to lead a Star Trek show. There have been black women ship captains, and strong supporting characters, before her, but none of them have ever been the center of the story. Even though she's not a ship captain to start, I think we can expect her career trajectory to head that way as the series develops.
