Going … going … gone. Television’s summer is officially under way, giving viewers their final opportunities to catch repeats of the series that won’t be returning next fall.

Friday’s most recent casualties include a once-popular show about God; a comedy once considered so essential to ABC’s future it survived star John Ritter’s untimely death; a military-themed drama with a 10-year track record; the last or at least the latest installment of the most popular sci-fi TV franchise of all time; a rude comedy misfire from “Passion of the Christ” producer Mel Gibson; and an offshoot of the can’t-miss “Law & Order” empire.

It’s now official: Friday nights have become the Bermuda Triangle of television.

So here’s a brief roundup of seven doomed shows airing repeats tonight: The family reflects on the car accident that left Kevin paralyzed on “Joan of Arcadia” (7 p.m., CBS); Cate throws a mortifying prom party on “8 Simple Rules” (7 p.m., ABC); Archer and crew preside over the decommissioning of the Enterprise on the two-hour series finale of “Star Trek: Enterprise” (7 p.m., UPN); the nasty lady next door needs help on “Complete Savages” (7:30 p.m., ABC); a war wound may have come from friendly fire on “JAG” (8 p.m., CBS); Claude makes a lousy match on “Less Than Perfect” (8:30 p.m., ABC); Kibre takes on the vigilante killer of a child molester on “Law & Order: Trial By Jury” (9 p.m., NBC).
