Pretty much the worst news you can receive, Life on Mars fans: the ABC drama has been canceled.

An insider told Michael Ausiello that the network has told the show's producers it will not be ordering a second season.

The silver lining is that writers should have enough to time pen a legitimate series finale. Unlike Pushing Daisies, Dirty Sexy Money, Eli Stone and other recently-canceled shows, ABC will actually air the show's remaining episodes this spring.
