“Before MARS” tells the story of Hana and Joon Seung, identical twin sisters who will grow up to be central characters in the global event series, “MARS” on National Geographic. Set in the present day, “Before MARS” focuses on the young twins’ move to a small town and the events that will one day inspire Hana to join humankind’s first expedition to another planet. Like the linear channel series, this short film focused on the theme of “home” and the characters’ lifelong desire to find their way in a foreign environment. “Before MARS” was released on all of Nat Geo’s digital platforms three weeks prior to the MARS broadcast premiere as a companion to the main series, and was promoted throughout the length of the series as a way to go deeper into the story of two of the series’ key characters.
