Yogi Rock is a rock on Mars that was discovered during the Mars Pathfinder mission in 1997, and named by Geoffrey A. Landis. The rocks found on the mission were named after famous icons and figures, and Yogi Rock was thought to resemble the head of a bear looking away from the spacecraft. As a result, it was named for the famed cartoon character Yogi Bear. Images of Sojourner approaching Yogi used in the opening credits of Star Trek: Enterprise made that television program the first science fiction television or film production to use footage taken on another planet.
