Summer drama “Salvation” has been renewed for a second season at CBS, the network announced Wednesday.

Season 2 will air in the summer of 2018 and will consist of 13 episodes. The series centers on Liam Cole, an MIT grad student, and Darius Tanz, a tech superstar, who bring Pentagon official Grace Barrows a staggering discovery – that an asteroid is just months away from colliding with Earth. Now with the added threat of nuclear war on the horizon, they work together with Secretary of Defense Harris Edwards to find a way to divert the asteroid, stop the war and save humanity before time runs out.

The series stars Santiago Cabrera, Jennifer Finnigan, Charlie Rowe, Jacqueline Byers, Rachel Drance, and Ian Anthony Dale. Liz Kruger, Craig Shapiro, Alex Kurtzman, Heather Kadin, Stuart Gillard and Peter Lenkov are executive producers for CBS Television Studios in association with Kurtzman’s production company, Secret Hideout.

The series drew decent ratings for a summer series on CBS, with Season 1 averaging a 0.52 rating in adults 18-49 and 3.5 million viewers per episode in the Nielsen Live+Same Day ratings. That puts it a nose above the third season of “Zoo” (0.51, 2.7 million) and the live-action game show version of “Candy Crush” (0.51 2.2 million), both of which also aired this past summer. In Live+7, the season averaged a 0.7 and 4.9 million viewers per episode.
