The summer drama suffered a sizable ratings drop in its second season.


CBS is trimming its summer roster.


The network has canceled drama Salvation after two seasons.


The Alex Kurtzman-produced series centered on an MIT grad student (Charlie Rowe) and a tech superstar (Santiago Cabrera) who brought a Pentagon official (Jennifer Finnigan) a staggering discovery — that an asteroid was just months away from colliding with Earth. The show followed the three as they searched for a way to divert the asteroid, stop a nuclear war and save humanity before time ran out.


The show's second season suffered a sizable ratings drop. Salvation averaged a same-day 0.3 rating among adults 18-49, down 40 percent from season one, and 2.67 million viewers, down 24 percent. It took three days of delayed viewing for the series to match its same-day numbers from the previous year.


Jacqueline Byers, Rachel Drance and Ian Anthony Dale also starred. The sci-fi series had returned with a 13-episode sophomore run in July and wrapped in September.


Salvation was one of Kurtzman's three CBS TV Studios series, which he produced in association with Kurtzman's Secret Hideout. He is also an exec producer on Hawaii Five-0 and CBS All Access' Star Trek: Discovery. Liz Kruger and Craig Shapiro served as showrunners and exec produced with Kurtzman, his producing partner Heather Kadin, Stuart Gillard and Peter Lenkov.


The cancellation of Salvation means that as of now, CBS has no returning scripted shows on its summer 2019 slate. The network has new series Blood & Treasure on tap for summer and could also extend one or more of its midseason dramas into the summer, as it did with Elementary and Code Black in 2018.
