Syfy is returning to outer space and bringing along Battlestar Galactica‘s Tricia Helfer in this first trailer for its upcoming miniseries thriller Ascension.

Ascension debuts Nov. 24 on Syfy, and though it’s billed as a limited series, I suspect if the show is successful that it could expand (like Battlestar after its original remake miniseries).
