Defying Gravity

Just think of ABC’s “Defying Gravity” as “Grey’s Anatomy” in space.

Here, characters talk about their love lives and lust after each other over experiments instead of surgeries and in spacesuits instead of scrubs.

The show, which premieres at 9 p.m. Sunday, even has its own Meredith and Derek in the form of star-crossed astronauts Maddux Donner (Ron Livingston, “Office Space”), a flight engineer, and Zoe Barnes (Laura Harris, “Women’s Murder Club”), a geologist.

The show takes place in the year 2052, just as eight astronauts from five countries are leaving for the trip of a life-time: a six-year “grand tour of the solar system,” during which time they’ll visit seven planets (first up: Venus) and travel eight billion miles in the International Space Organization’s (ISO) Antares ship.

Other astronauts on the flight include, among others, Donner’s best friend, and Antares’ commander, Ted Shaw (Malik Yoba, “New York Undercover”), whose wife also works for ISO; Zoe’s best friend, Jen (Christina Cox, “Blood Ties”), a biologist, and her husband, Rollie; and the show’s comic relief, physicist Steve Wassenfelder (Dy-lan Taylor), whose frequent use of the word “dude” reminded me of “Lost’s” Hurley.

That’s not the only thing that was reminiscent of the cult series.

“Defying Gravity” also employs flashbacks — to Donner’s previous mission to Mars, which has left him scarred, and to this current group of astronauts as they trained for the Antares mission — and there’s an overarching, possibly supernatural mystery surrounding the flight.

Complications arise almost as soon as the ship blasts off, and the higher-ups at ISO keep talking about “it” and what “it” wants for the mission. I have no clue what that’s all about, but I’m intrigued.

The supernatural feel continues when Zoe starts hearing the sound of a baby crying on the — maybe haunted? — ship. Is it all in her own, tortured mind, or is the unknown entity “it” responsible?

I, for one, want to find out.

Take this show for what it’s worth. It’s not going to win any Emmys, or even much critical acclaim, but it’s good, fun summer entertainment.
