Laurence Fishburne hosts the new series “History’s Greatest Mysteries” (History, 9 p.m.) which revisits still-puzzling tales of the last century or so. First off is the hunt for D.B. Cooper, the name given for the 1981 hijacker who got away with the cash he demanded only to be never seen again in what is called the only unsolved skyjacking in U.S. history. Eric Ulis, pictured left, is back scouring the Pacific Northwest woods. 

What would have been a swell Saturday night viewing — the launch of Crew-1 by SpaceX and NASA to the International Space Station — has been postponed because of weather. It’s been rescheduled to Sunday night on Discovery and Science channels, where it will be one of a wealth of offerings. 

Just as it gets cold, “Earth’s Great Seasons” (BBC America, 8 p.m.) moves to spotlight summer. 

On the second episode of “The Cult of the Family” (Starz, 8:30 p.m.), children rescued from the cult go back to their normal lives, while the cult leader is sought by detectives. 

“Eli Roth’s History of Horror” (AMC, 10 p.m.) categorizes scary movies into nine distinct categories.
