Multiple sources are confirming that ABC has canceled my beloved Life on Mars. Per an insider, the network advised the show's producers earlier today that it would not be ordering a second season. The heads-up will allow them to make this year's season finale a series finale, thus leaving no questions unanswered. And unlike Pushing Daisies, Dirty Sexy Money, Eli Stone, etc., all indications are that ABC will actually air this series finale. We're making progress, people!
