Marta McFly's ship was sabotaged by Griff Tannen's grandson Ziff Tannen, but Jules and Verne came to the rescue with MSC's prototype ship, the MSC Jennifer. With the help of Doc and Clara, Marta saved the ship and returned to Earth safely. Marta was also the head of the McFly Space Cruises company, which owned the MSC Jennifer and presumably the McFly Space Center from which the ship departed. She hired an impersonator of her great-grandfather Marty to perform his music on her cruise ship.
