Outer space, also known as deep space or space, is the void that exists between celestial bodies, including Earth.
In 1866, Clara Clayton came down with diphtheria and was quarantined for three months. Her father, Daniel Clayton, placed a telescope by her bed, which she used to look at the Moon and the stars — igniting her love in astronomy and science.
In the 1870s, Daniel Clayton tried to introduce Clara to young men from good families, but she was always reading From the Earth to the Moon and other Jules Verne novels, so the relationships never worked out.
In 1885, Clara discussed with Emmett Brown their mutual love for Jules Verne novels, and they viewed the Moon and the stars through Clara's telescope — during which Clara appeared to know where a lot of the constellations were, and also pointed out the Moon crater Copernicus to Doc.
In 1992, Doc went into space to fix a satellite, in exchange for free premium cable service.
In 2091, Marta McFly ran the McFly Space Center. Her solar sail ship, the MSC Marty, was sabotaged by Ziff Tannen. The ship was saved by Jules and Verne Brown, who traveled into the future to save their parents, who were aboard the ship at the time.
