1) “MasterChef,” 8 p.m., Fox. These are home-chefs from the U.S., but the emphasis is global. Four five-person teams will be chosen, representing roots in Europe, Africa, Asia-Pacific and the Americas. The opener is Europe, including family links. One chef’s grandma finished 14th in 2015; another (shown here) saw her husband finish fifth in 2021.
2) “Nova,” 9 p.m., PBS. Now that TV has covered the return of the Artemis II moon mission, it’s time for an overview. This documentary looks at the unmanned Artemis I and the adjustments that were made afterward. It follows through to the flight and return.
3) “Nature,” 8 p.m., PBS. Wrapping up a two-week documentary, it’s time to release the oldest elephant orphans, age 7, into the wild. But new work arrives quickly — a baby elephant that fell into a water hole … an orphaned zebra … and one of the 7-year-olds, back with an injury. It adds up to a genltly emotional story of good people, ready to rescue.
4) “Scrubs” season-finale, 8 p.m., ABC. This revival finally brings Jordan Sullivan (Christa Miller) back. She’s been a hospital board member and Dr. Cox’s wife; they divorced … but resumed the relationship and lived together. Now she shows up during a chaotic day. That’s followed by date night on “Abbott Elementary,” which wraps its season next week.
5) “Titanic” (1997), 6 p.m., Paramount Network; rerunning at 10:30. Also at 8 p.m., Showtime. Choose your time to catch this epic. The rare film that triumphed in both big-deal visuals and intimate drama, it won 11 Academy Awards, including best picture.
